Il problema della categorie logiche è stato affrontato fin dall’antichità greca, principalmente ad opera di Aristotele, ma è nel Novecento che l’interesse per lo studio dei processi di categorizzazione ha avuto uno sviluppo decisivo. A partire dalle analisi filosofiche di Wittgenstein nella prima metà del secolo scorso, si è arrivati negli anni ‘60 e ‘70 a un approccio empirico nello studio dei modi in cui l’essere umano interpreta e concettualizza il mondo circostante. Ogni volta che parliamo, applichiamo un preciso processo cognitivo per individuare, definire, organizzare gli elementi del discorso, sia a livello linguistico che a livello concettuale. Questo elaborato intende riassumere gli approcci principali allo studio e alle teorie di tale processo, mettendo in rilievo in particolare il ruolo dei modelli cognitivi nell’espressione linguistica. Il nostro utilizzo del linguaggio, infatti, è strettamente collegato a delle rappresentazioni concettuali dipendenti dal nostro ambiente, dalla nostra cultura e da altri fattori extralinguistici.

Full textAbstract:
Lo studio realizzato ha avuto l’obiettivo di analizzare la fattibilità del riciclo e riutilizzo di rifiuti e svolgere l’analisi ambientale di tre casi studio che ad oggi sono destinati in discarica in quanto non riciclabili dalle attuali filiere, dunque tali rifiuti non sono utilizzati come materie prime seconde.
I tre casi studio sono stati oggetto di 3 progetti di ricerca finanziati da fondi pubblici che hanno avuto l’obiettivo di valutare l’applicabilità delle diverse strategie di utilizzo come materie prime seconde e gli impatti ambientali del riciclo.
Il primo caso studio si è focalizzato sul riciclo e riutilizzo di materiali contenti amianto, in particolare sono state valutate le emissioni atmosferiche relative al processo termico di trattamento, e la conseguente valutazione ambientale in base alla normativa vigente e conseguente valutazione degli impatti ambientali con metodo LCA.
Il secondo caso studio ha permesso di valutare la fattibilità del riciclo di plastiche dure domestiche non da imballaggio. È stata dimostrata la possibilità di separare le diverse plastiche dure per densità, inoltre è stato possibile ottenere un blend con buone proprietà meccaniche composto da plastiche post-consumo e plastiche post-industriali. L’analisi LCA ha permesso di valutare una considerevole riduzione degli impatti ambientali comparati con la produzione di nuova plastica vergine.
Il terzo caso studio ha preso in analisi la possibilità del riutilizzo di cellulosa proveniente da Assorbenti per uso personale (PSA) ottenuta dal processo di riciclo brevettato da Fater S.P.A.. I test svolti durante il progetto hanno permesso di valutare l’utilizzo della cellulosa riciclata sia per la realizzazione di pannelli isolanti sia come cellulosa in fiocchi. È stato dimostrato come la cellulosa riciclata ha le stesse proprietà della cellulosa vergine per l’isolamento termico di edifici e come l’applicazione di pannelli isolanti è un valido metodo di utilizzo con un contenuto impatto ambientale.The aim of the study was to analyse the feasibility of recycling and reuse of waste and to carry out an environmental analysis of three case studies that are currently destined for landfill because they cannot be recycled by the current supply chains and are therefore not used as secondary raw materials. The three case studies were object of three research public projects aimed to assessing the applicability of different strategies to use as secondary raw materials and the environmental impacts of recycling. The first case study focused on the recycling and reuse of materials containing asbestos. In particular, the atmospheric emissions related to the thermal treatment process were evaluated, and the consequent environmental impact assessment using the LCA method. The second case study assessed the feasibility of recycling household hard plastics. The possibility of separating the different hard plastics by density was demonstrated, and it was possible to obtain a blend with good mechanical properties composed of post-consumer and post-industrial plastics. The LCA analysis showed a considerable reduction in environmental impacts compared to the production of new virgin plastics. The third case study analysed the possibility of reusing cellulose from Absorbent Health Products (AHP) obtained from Fater S.P.A.'s patent recycling process. Tests carried out during the project allowed to evaluate the use of recycled cellulose both for the production of insulating panels and as cellulose flakes. It has been demonstrated that recycled cellulose has the same properties as virgin cellulose for the thermal insulation of buildings and that the application of insulation panels is a valid method of use with a low environmental impact.

Full textAbstract:
In questo lavoro si è voluto mostrare lo sviluppo di nuove tecniche per la diagnosi del tumore alla mammella, in particolare la tecnica di imaging a microonde.
Fra le varie metodologie di imaging della mammella, la Microwave Imaging è particolarmente interessante in quanto sfrutta il contrasto nelle proprietà elettromagnetiche dei tessuti.
Questa emergente tecnica offre numerosi vantaggi per le pazienti eliminando la compressione della mammella tipica delle mammografie a raggi-X, e l'uso di radiazioni ionizzanti e dannose per l'uomo.
Per tali motivi, la ricerca in campo biomedico, dal 2000 in poi, si è interessata particolarmente all' uso delle onde elettromagnetiche nel range delle microonde per ottenere immagini diagnostiche.
Il presente lavoro si propone di illustrare lo stato dell'arte attuale nel campo dell'imaging a microonde, descrivendo dettagliatamente i vari prototipi sviluppati in tutto il mondo, e infine esporre i risultati che i vari gruppi di ricerca hanno ottenuto.
Anche se la tecnica, per le sue potenzialità, dovrebbe avere un largo uso clinico, solo pochi dei sistemi realizzati sono stati testati su pazienti a scopo diagnostico.

All’interno delle produzioni ceramiche nello stile di Kamares, che caratterizzano le fasi protopalaziali del Bronzo Medio a Creta (XIX-XVIII sec. a.C.), è possibile individuare alcune classi che mostrano chiari rimandi a prototipi in vasellame metallico, determinati da una serie di caratteri skeuomorfici.
A partire da un esame sulle produzioni fini che presentano queste caratteristiche, questo lavoro si è particolarmente occupato della ceramica con decorazioni impresse tramite uno stampino, ripetute in sequenza.
Accanto al catalogo sistematico degli esemplari, in gran parte inediti, si sono indagati i dati offerti dalla diffusione e dalla cronologia relativa, gli aspetti di carattere tecnologico legati alla produzione e i rapporti con altre classi di materiali come la glittica.

Le tecnologie di fabbricazione additiva permettono la produzione diretta di prodotti e componenti pronti per l'uso, indipendentemente dalla loro complessità di forma. Questo porta all’esplorazione di nuove metodologie progettuali e produttive.
In questo elaborato vengono presentate la progettazione e la realizzazione di prototipi di alcuni componenti di un sedile per aereo passeggeri. Sono stati ri-progettati il tavolino e il porta bicchiere del sedile presi da un modello CAD già esistente, in modo da renderli un unico pezzo con meccanismi non-assembly, ovvero tale che più componenti risultino già collegati da cerniere create direttamente nella stampante e che non richiedono l’assemblaggio. Questo metodo permette di creare facilmente e velocemente varianti di prototipi per la valutazione dell’interazione e dell’usabilità ottimizzando tempi e costi.

Lo scopo di questo lavoro di tesi è stato lo studio e la realizzazione di un sistema di basso costo per l’analisi automatica dei parametri spazio-temporali del cammino. Il sistema è costituito da un PC, una webcam e da uno a tre smartphone, basati su sistema operativo Android; gli smartphone sono stati usati essenzialmente come sensori accelerometrici per misure temporali, mentre la webcam ha permesso misure spaziali. Sul Pc è stato realizzato un software che guida l’utilizzatore nel processo di acquisizione ed elaborazione dei dati, permettendo la visualizzazione dei segnali sia in real-time che durante le fasi di elaborazione; sono state implementate inoltre altre funzioni di supporto come la calibrazione del sistema accelerometrico e della webcam e la visualizzazione dei dati in 3D. Il sistema provvede autonomamente a tutte le fasi, dall’acquisizione all’elaborazione, pertanto nessun software esterno è richiesto per effettuare ulteriori elaborazioni.
Nella realizzazione del sistema la prima fase è stato lo sviluppo di una piattaforma software di base, su cui installare diverse applicazioni per i diversi tipi di movimento che si intendeva studiare. La seconda fase è stata la realizzazione di varie applicazioni sulla piattaforma per studiare diverse situazioni connesse al cammino che sono:
• Protocollo Timed Up and Go, misura dei tempi di alzata da una sedia, percorrenza di 3m, rotazione, ritorno e seduta;
• Misura di lunghezza, larghezza e durata di passo per un soggetto che cammina su pavimento utilizzando markers riflettenti colorati;
• Misura di lunghezza, larghezza e durata di passo per un soggetto che cammina su tapis-roulant utilizzando markers riflettenti colorati;
• Misura di lunghezza, larghezza e durata di passo per un soggetto che cammina su tapis-roulant senza utilizzare markers;
• Acquisizione contemporanea di punti nello spazio 3D, relativi all’intersezione del corpo in movimento con dei piani di luce laser paralleli al suolo, per misurare le successive posizioni nello spazio del tronco inferiore.The purpose of this PhD thesis has been the study and the realization of a low cost system for the automatic analysis of the spatial-temporal parameters of gait. The system consists of a PC, a webcam and from one to three smartphones, based on the Android operating system; smartphones were used primarily as acceleration sensors for measuring time, and the webcam has been used for spatial measurements. The system software guides the user throughout the process of data acquisition and processing, allowing the display of signals in both real-time and during processing; other support functions have been implemented such as accelerometer and camera calibration and to display data in 3D. The system works in a completely automatic way. In the realization of the system the first phase has been the development of a basic software platform, on which to install different applications for different types of movement that is intended to study. The second stage was the development of various applications to study gait in various situations which are: • Timed Up and Go protocol, measuring the times needed to stand up from a chair, to walk for three meters, to turn, to come back, and to sit down; • Measurement of length, width and duration of steps for a person walking on the floor using colored reflective markers; • Measurement of length, width and duration of steps for a person walking on a treadmill using reflective markers colored; • Measurement of length, width and duration of steps for a person walking on a treadmill without using markers; • Simultaneous acquisition of points in 3D space relative to moving body segments, by means of linear lasers.

Full textAbstract:
Il lavoro ha avuto come oggetto l'indagine sui rotori a resistenza
ad asse verticale. L'approccio seguito ha coinvolto sia l'evidenza
sperimentale che la modellazione numerica. I due approcci sono
complementari: il modello numerico, mettendo alla luce le cause
fluidodinamiche del meccanismo di conversione energetica, conduce
alla definizione del rotore. I test sperimentali si sono occupati di
elementi esterni al rotore e difficilmente ripetibili nel modello
numerico. Per questo gli obiettivi si sono differenziati per i due
approcci.
Nei test sperimentali svolti in galleria del vento si è voluto
determinare le configurazioni in grado di migliorare le prestazioni
di un dato rotore. Nelle analisi numeriche si è studiato il campo di
moto e quindi ipotizzate nuove geometrie rotoriche. Il rotore di
riferimento per entrambi gli approcci è un Savonius “classico” a pale
semicircolari dritte, con schermi di estremità per riprodurre la
bidimensionalità del modello numerico.
Le prestazioni sono valutate in curve CP-lambda; il primo è il
coefficiente di Potenza, il secondo è il rapporto tra la velocità di
rotazione e quella del flusso incidente.
La configurazione sperimentale che risulta migliore è quella che
adotta contemporaneamente schermi, convogliatore e deflettore. Il CP
massimo vale 0.3, ossia +25% rispetto al riferimento.
I risultati CFD hanno evidenziato due geometrie: il Savonius
classico senza albero centrale e un modello definito “a profilo
invertito”. Per entrambi il CP massimo vale circa 0.29 senza
l’utilizzo di appendici esterne.
Infine è stata realizzata una postazione di prova all'esterno per
test su modelli full-scale di sistemi alimentati da fonte eolica.
Essa è composta da una piazzola per i prototipi, una torre
meteorologica di 10 metri e una postazione Sodar-Rass.
E’ emerso che il sito è caratterizzato da brezze locali per gran
parte dell'anno e una direzione prevalente di 330 gradi.
La postazione esterna è funzionante e attualmente un primo
prototipo di lampione eolico è oggetto di studi sperimentali.This work is focused on drag driven vertical axis wind turbines. The study involved both experimental measurements and numerical analyses. The two methods are complementary: CFD analyses allow us gain an insight into the rotor's fluid dynamics that lead to energy production. The experimental measurements allow us to evaluate the elements that are difficult to put inside a numerical model. For this reason the two approaches have different aims. The experiments have been performed in a closed circuit wind tunnel. They investigate the configurations that could improve the performance of a given rotor. The numerical analyses were conducted to improve the flow field knowledge and to design new rotor's geometries. Both approaches started from a classic Savonius rotor equipped with semi-circular straight blades S-shaped, with end plates to replicate the two-dimensional effects of the numerical model. The performance were evaluated with CP-lambda plots, where CP is the Power coefficient and lambda is the rotation velocity versus wind speed ratio. The best experimental configuration correspond to the reference rotor with conveyor and deflector: its CP max was 0.3, with +25% gain with the respect of the reference rotor. CFD analyses have shown two best geometries: the classical Savonius without the central shaft and a new geometry defined as “reversed profile”. They have both a CP maximum around 0.29 without any external appendices. Finally an external test station was build up to perform experimental measurements on full-scale small wind turbines models. It is composed by a test station for prototypes, a 10 meters meteorological mast and a Sodar-Rass station. It was found that the site is characterized by local breezes blowing most of the year and a prevailing direction of 330 degrees. The external station is operational and an urban lamppost prototype supplied by wind energy and is currently the subject of experimental studies.

Full textAbstract:
Il presente elaborato propone un metodo di calibrazione alle basse velocità degli anemometri a filo caldo utilizzati nella galleria del vento presente al C.I.C.Lo.P.E. (Center for International Cooperation in Long Pipe Experiments) dell'Università di Bologna, potenzialmente estendibile ad applicazioni più generali.
In seguito ad un'analisi teorica approfondita della fattibilità di una calibrazione alle basse velocità, si è dimensionato e realizzato un prototipo in P.V.C. a geometria convergente-divergente, ritenuto in grado di produrre un flusso uniforme in uscita tale da garantire una soluzione al problema della calibrazione all'interno della test-section della galleria. Completata la fabbricazione del componente si è condotta un'analisi sperimentale, con l'ausilio del C.A.T. (Coaxial Air Tunnel) presente nell'hangar della Scuola di Ingegneria, sede di Forlì, del flusso generato internamente al divergente del calibratore.
Nonostante si sia rilevata, mediante lo studio sperimentale condotto, una non perfetta uniformità del flusso uscente dal componente, i risultati riscontrati hanno permesso di inquadrare approcci e soluzioni atti ad un'ottimizzazione del calibratore, lasciando ampio margine di miglioramento ai fini della calibrazione alle basse velocità mediante il metodo descritto.

Questo lavoro di tesi partendo da un'analisi bibliografica delle tecnologie di batterie più avanzate allo stato solido e a flusso, sottolinea le potenzialità delle batterie metallo aria in particolare Li/O2 per applicazioni stazionarie e per il veicolo elettrico.
L'ottimizzazione delle prestazioni delle batterie a flusso richiede un'accurata ingegnerizzazione del disegno di cella e studi di fluidodinamica per la valutazione dell'impatto dei flussi sul funzionamento della batteria. Le cadute di pressione attraverso la cella generano, infatti, una perdita di potenza che deve essere minimizzata mediante opportune geometrie di cella.
Lo scopo di questa tesi è la modellizzazione e la valutazione sperimentale delle cadute di pressione attraverso prototipi di laboratorio di celle Li/O2
L’analisi dei disegni di celle a flusso proposte in letteratura ha permesso di realizzare un primo prototipo ottenuto con stampa 3D cha ha evidenziato come un intelligente geometria di cella permetta di ridurre drasticamente le cadute di pressione anche con sistemi viscosi quali gli elettroliti organici utilizzati nelle batterie a più alta energia specifica.
L'integrazione tra simulazioni numeriche e prove elettrochimiche su celle Li/O2 reali ha permesso di proporre il disegno di un terzo prototipo di cella sempre con l'obbiettivo di massimizzare la potenza netta della cella.
Da sottolineare che l'accuratezza della descrizione fluidodinamica nei prototipi virtuali studiati ha avuto conferma dalle misure sperimentali effettuate.
Questa tesi pertanto contribuisce a dimostrare come gli approcci numerici utilizzati siano metodi estremamente potenti per accelerare l'attività di prototipazione di batterie redox a flusso avanzate, in particolare metallo aria, e per portare tali tecnologie a raggiungere valori di energie e potenze specifiche superiori rispetto allo stato dell'arte.

Inbyggda system blir allt vanligare i dagens samhälle. De inbyggda systemen finns i nästan allt nuförtiden, från diverse fordon till leksaker för barn.
Dagens teknik innebär bland annat att gårdagens lösningar kan realiseras på en bråkdel av den tidigare ytan. Allt mer blir ytmonterat med mindre och mer komplexa kretsar. Detta är inte alltid till utvecklarnas fördel då montering av prototypkort blir en svår och/eller dyr process.
Målet är att ta fram ett inbyggt system med en ARM-processor. Systemet ska innehålla USB-OTG, ethernet, minne av olika slag som FRAM och microSD samt en display med pekskärm för användargränssnitt. Projektet omfattar allt från komponentval till test och verifiering med programkod.
Tiden räckte inte till för att få med alla delar som planerats. Resultatet av projektet blev ett prototypkort och två små programsekvenser, en som blinkar två lysdioder på kortet och en som skriver ut en bild på displayen.
Detta inbyggda system är i första hand till för utvärdering av ARM-processorer för Mikrodidakt AB.

Full textAbstract:
Enligt statistiken år 2010 fanns det 26 individer sett från en grupp på 100.000 som var tilldelade oxygenbehandling i hemmet. Oxygenbehandlingen tillför en bestämd mängd oxygen till bäraren då möjligheten att själv förse sig med rätt mängd för överlevnad hämmats. Den dominerande sjukdomen till oxygenbehandling i hemmet är KOL, kroniskt obstruktiv lungsjukdom. Som namnet antyder är det en kronisk sjukdom som ger inflammatoriska förändringar i lungans bronkioler. Dessa förändringar minskar andningsytan vilket resulterar i att individens andningskapacitet reduceras. Projektet använde metoder från dynamisk produktutveckling med användaren i fokus. Detta för att få fram en funktionell prototyp som kunde användas utav avsedd målgrupp och uppfylla det syfte, mål och krav som ställdes på projektets resultat. En viktig komponent som projektet därför arbetade med var insamling av data. För detta användes olika metoder som kunde tillskaffa sig information från både användare och förskrivare av oxygenbehandling. Samtliga av de metoder som användes var beprövade sedan tidigare och projektet kunde därför med fördel genomföra intervjuer, observationer, matrisuppställningar, riskanalyser samt användartester på patienter med oxygenbehandling. Prototypen som togs fram i projektet resulterade i att avsedd målgrupp kunde utföra testmoment på den utan att det förekom risker med användandet. Resultatet uppfyllde därför syftet och målet med projektet som riktade sig mot att patienter skulle få möjlighet till att förflytta den syrgasslang som används vid oxygenbehandling. Vidare kunde slutsatsen dras att resultatet uppfyllde patienternas önskemål om att ta fram en möjlighet till förflyttning av syrgasslangen i hemmet samtidigt som det besvarade de frågeställningar som projektet strävade efter att besvara. Det fanns inga befintliga lösningar på det problem som beskrevs i projektet och det gav möjlighet att framställa en första prototyp som uppfyllde syftet och målet.According to statistics, in 2010 there were 26 individuals seen by a group of 100,000 who were depending in home oxygen therapy (HOT). Oxygen treatment adds a certain amount of Oxygen to the patient because the ability to breathe correctly and sufficiently is negatively affected. The dominant disease that leads to HOT is COPD, chronic obstructive pulmonary disease. As the name suggests, it is a chronic disease which gives inflammatory changes to the lung bronchioles. These changes affect the breathing surface which results in that the individuals’ respiratory capacity becomes reduced. The project used methods from dynamic product development with the user in focus. This to obtain a functional prototype that could be used by the target group and to fulfill the purpose, goals and requirements set for the project's results. An important component of the project therefore was to work with the collection of data. For this, various methods were used to obtain information from users as well as prescribers of HOT. All of the methods used have been tested earlier and proven reliable. This project collected information from interviews, observations, matrix arrays, risk analysis and usability testing in patients with HOT. The prototype developed in the project resulted in that the target group could perform live test without any risks during testing. The results showed that the aim and objective for the project were fulfilled, expressed in that patients would be able to move the oxygen tube used in HOT. It was further concluded that the results fulfilled the patients' desire and opportunity to move the Oxygen tube in their home and at the same time answered the questions that the project was to answer. There were no existing solutions to the problem which is included in the project, but it was possible to develop a first prototype that met the purpose and object of the project.

So far, the department did not have such kind of equipment. Thus, developing the new, it will be possible to improve the study quality, whereas is will be easier to explain the operation of complicated processes. Herewith, similar virtual experimentation was performed using electrical circuit simulation software. However such method of teaching was idealised, therefore it did not meet the reality very much. It was intended to develop two different laboratory equipment sets in relation with the requirements of the Power Electronics course. These include SCR control and voltage inverter modules. In the initial stage, the respective electrical circuits were simulated using “MULTISIM”. Further, the real electrical circuits were designed, made and tested. The simulation and real systems analysis results were in good agreement. The descriptions of the equipment were prepared, which can be used for the laboratory practice. The students will have to perform respective tasks and measurements and familiarise themselves with the principles of power electronic circuit operation. Conclusions: The equipment testing results were in conformity with the theory, therefore they are operating appropriately. Students will be able to obtain appropriate knowledge concerning power electronics devices in the real environment. The price of production of the... [to full text]

This report is a product development project of a ball launcher as requested by Sörmons HundklubbLKk. The project har been carried out as a thesis for the Bachelor of Science for the Innovation anddesign engineer program at Karlstad University.The client wished to begin training in a dog sport called Flyball. This sport can be likened to a relayrace where two teams of dogs race against each other. One dog per team runs along a path, leapingover obstacles, up to a ball launcher. When the dog jumps at the ball launcher to stop its momentumand turn back, a ball, launched about two feet, is to be caught by the dog. The dog then returns thesame way along the track as it came to switch with the next dog on the team. The last dog who finishfirst wins for their team.Due to large costs when importing a ball launcher, and the product not being available in Sweden,the client wanted a Swedish version developed. The goal was to minimize the price with the criterionto maximize longevity.The work of the project has followed the product development process as studied at KarlstadUniversity, with great influence by idea generation techniques, analog and digital sketching, 3Dmodeling and mechanical drawing techniques. Construction of the prototype has been carried out inthe workshop at Karlstad University with an evolutionistic design approach. A combination of lateralthinking for creativity and vertical thinking for logic and confirmation was used throughout theproject.The result of the project was a prototype that could be tested in a real environment at the dog cluband was confirmed to function as desired. Due to the availability of material at the workshop,construction of the ball launcher was possible at no cost to the client. This was a request, althoughnot a requirement for the project.The client also wanted to keep the prototype which was constructed to use within the club fortraining purposes. Therefore the ball launcher was completed to a finished prototype after projectclosure.Denna rapport behandlar ett produktutvecklingsprojekt av en bollutslungare på uppdrag av SörmonsHundklubb LKk.

Full textAbstract:
This bachelor thesis aims to present an overview of the performed steps to construct and program a prototype of a mechanical mirror. The idea of a mechanical mirror is that a camera captures an image that is translated into pixels of different brightness values. The brightness values are later displayed by metal plates, acting as pixels, rotated to different angles to reflect a corresponding light from a lamp. The pixels together shape grayscale images based on the frames captured by the camera. A prototype was constructed successfully. Tests showed that its purpose to move according to the captured image was fulfilled although adjustments could be made for the light to reach all the pixels to a greater extent. The angle span for the pixels turned out to be between 32°and 44°, which proved sufficient for their purpose. The reason for a difference in angle spans between the pixels was due to minor construction errors and was not an issue of functionality for the mirror. The refresh rate of the mirror, which could be described as the frequency at which the pixels rotate and shape an image, was set to 25 frames per second. This allowed the mirror to mimic movements in front of it without much delay while not exceeding the frame rate of the camera, which capture at a frame rate of 30 frames per second. The camera was therefore the vital limitation for the refresh rate of the mirror.Detta kanidatexamensarbete har syftet att presentera en översikt av de steg som genomfördes för att konstruera och programmera en prototyp av en mekanisk spegel. Idén med en mekanisk spegel är att en kamera läser in en bild som sedan är översatt till pixlar med olika värden på ljusstyrka. Dessa ljusstyrkor visas sedan av metallplattor, vilka agerar som pixlar, som roterar till olika vinklar för att reflektera motsvarande ljus från en lampa. Pixlarna formar tillsammans gråskalebilder baserat på de bilder som kameran läser in. En prototyp konstruerades framgångsrikt. Test visade att dess syfte att röra sig i enlighet med den inlästa bilden uppfylldes, dock finns plats för justeringar för att ljuset från lampan ska nå pixlarna i större utsträckning. Pixlarnas vinkelomfång visade sig bli mellan 32°och 44°, vilket konstaterades vara tillräckligt för deras syfte. Skillnaden i vinkelomfång mellan pixlarna berodde på mindre konstruktionsfel och påverkade inte spegelns funktionalitet. Spegelns uppdateringsfrekvens, vilket kan beskrivas som frekvensen med vilken pixlarna roterar och formar en bild, sattes till 25 bilder per sekund. Detta tillät spegeln att härma rörelser framför den utan stor fördröjning utan att överstiga kamerans bildhastighet, som läser in med en bildhastighet på 30 bilder per sekund. Kameran var således den begränsade faktorn för pixlarnas uppdateringsfrekvens.

Denna uppsats är ett projekt där målet var att utveckla en beta-prototyp för en beteendeanalysanordning för hundar. Enheten använder rörelsespårningssensorer för att analysera och förutsäga dess beteende. Examensarbetet började med att analysera kundsegmentet och definiera designriktningen baserat på den grunden. Detta följdes sedan av konceptutveckling, realisering och utvärdering. Detta inkluderade traditionella designmetoder och designförfaranden där designerna utvärderades och modellerades. Detta var en mycket iterativ designprocess som följdes av Moldflow-analyser. Prototyper gjordes vid KTH: s Prototypcenter, där olika versioner tillverkades i FDM-skrivare och validerades. Beta-prototypen producerades senare med SLA-skrivare och validerades med avseende på vattentäthet. Dropptest simulerades med ANSYS för att bestämma deformationen av enheten när de släpps och resultaten pekar på att enheten med god marginal befinner sig inom acceptabelt deformationsintervall. Moldflowanalyserna belyste aspekter av designen som krävde ytterligare modifieringar för att förbättra produktens tillverkningsbarhet.This thesis is a project where the aim was to develop a beta prototype for a behaviour analysis device for dogs. The device uses motion tracking sensors to analyse and predict its behaviour. The thesis project started with understanding the customer segment and defining the design direction on that basis. This was then followed by concept generation, realisation and evaluation. This included traditional design methodologies and design procedures where the designs were evaluated and modelled. This was a highly iterative design process which was followed by FEA and Moldflow analyses. Prototypes were made at the KTH prototyping centre, where various versions were made in FDM printers and validated. The beta prototype was later produced using SLA printers and validated for waterproofing. Drop test was simulated with Ansys to determine the amount of deformation in the device when dropped, the results point out that the device is well within an acceptable deformation range. The Moldflow analyses highlighted aspects of the design that required further modifications to improve the manufacturability of the device.

Full textAbstract:
This master thesis was made at the Institute of Technology Stockholm and is a part of a robot hand project called 10-X with the aim to develop a low-cost robot hand that is light and strong.
The project specification is to further improve the ability to control the robot hand in a user friendly way. This has been done by implementing a controller, earlier used and developed at KTH, which is intuitive and easy to customize after the needs in different kinds of grasps. To make the controller easy to use an user interface has been made.
Before the implementation of the controller was made on the real hand it was tested and development on a simulation created in MATLAB/simulink with help from a graphic physics engine called GraspIt! The movement of the robot finger is effected of the force from a leaf spring and a tendon that bends the finger. Also the finger is exposed of contact forces and all these components had to be modeled in the simulation to make the finger act properly.
Detta examensarbete är genomfört på KTH Stockholm och är en del av ett projekt, kallat 10-X, vars syfte är att utveckla och ta fram en robothand som är lätt och stark samtidigt som den är billig.
Projektets målsättning är att vidare förbättra och utveckla möjligheten att kontrollera robothanden på ett användarvänligt sätt. Detta har gjorts genom att implementera en regulator, tidigare utvecklad och använd på KTH, som är instruktiv och lätt att anpassa efter olika typer av grepp. För att göra regulatorn enkel att använda har ett användargränssnitt skapats.
Innan regulatorn implementerades på den riktiga robothanden utvecklades och testades den på en simuleringsmodell, skapad i MATLAB/simulink med hjälp av en grafisk fysikmotor GraspIt! Rörelsen hos ett robotfinger påverkas av krafter från en bladfjäder och den lina som böjer fingret. Fingret utsätts också för kontaktkrafter och alla dessa komponenter blev modellerade i simulatorn för att få fingret att bete sig korrekt.

RECCO AB är ett företag som utvecklar räddningssystem för lavinolyckor. Systemet fungerar genom en RFID tag (reflektor) och en detektor. Detektorn känner av reflektorn som sitter på jackan, hjälmen, skon eller pjäxan upp till 200 meters avstånd eller 30 meter genom snön. Detektorn används av erfaren lavinräddningspersonal. RECCO ska implementera reflektorer i vandringsskor för att söka efter människor som är i skogen och uppe i bergen. Syftet med examensarbetet är att utveckla en skotestmaskin som ska kunna testa livslängden på reflektorn. Bakgrundsundersökningen genomfördes genom en informationssökning om biomekanik i ben och fot, olika benrörelser som kan påverka skon, olika typer av vandringsskor och olika skotestmaskiner som finns ute på marknaden idag. Genomförandet av projektet inleddes genom ett test för att undersöka hur stora krafterna är som påverkar reflektorn i skon. Testet genomfördes med en tryckkänslig sensor och en Arduino UNO. Den maximala kraften på reflektorn blev 7.1 N. Därefter gjordes en brainstorming som resulterades i sju olika koncept. Koncepten vägdes emot varandra med hjälp av en PUGH matris, som resulterade i att ett koncept valdes att gå vidare med. Analysen av konceptet genomfördes med Solidworks, Matlab och ADAMS. Med SolidWorks gjordes detaljerade ritningar och ett montage av modellen. Med Matlab gjordes beräkningar på lagerhus, glidlager, kulbussning och motor. ADAMS användes för att simulera rörelsen och för att verifiera Matlab-beräkningarna. Resultatet av slutprodukten blev lyckat. Maskinens rörelse och de påverkande krafterna på reflektorn efterliknar testet som genomfördes i början av projektet. Eventuella förbättringar som kan utföras är inköp av en starkare motor för att uppnå en mer konstant hastighet eller ett svänghjul för att minska påfrestningarna på motorn. För vidare arbete på slutprodukten kan RECCO programmera en strömbrytare som stänger av motorn vid uppnått antal cykler.RECCO is a company that develops rescue system for avalanche accidents. The system works by a RFID tag (reflector) and a detector. The detector senses the reflector that is attached to jackets, helmets, shoes and ski boots up to 200 meters or 30 meters through the snow. The detector is used by experienced avalanche rescue groups. RECCO will implement reflectors in hiking shoes to search for people who are in the woods and in the mountains. The purpose of this master theses is to develop a shoe test machine to be able to test the service life of the reflector. The background study was performed by an information search about the biomechanics of the leg and foot, different leg movements that may affect the shoe, different types of hiking shoes and several shoe test machines available on the market today. The implementation of the project began with a test to examine how large the forces are on the reflector acting in the shoe. The test was conducted by a pressure sensitive sensor connected to an Arduino UNO. The maximum force on the reflector was 7.1 N. This was followed by a brainstorming session that resulting in seven different concepts. The concepts were then evaluated against each other using a PUGH matrix, which resulted in a concept for further development. The analysis was conducted using SolidWorks, Matlab, and ADAMS. Detailed drawings and assembly of the model were made using SolidWorks. The calculations were made on bearing housings, plain bearings, linear ball bearing and the motor using Matlab. ADAMS was used to simulate the movement and to verify the Matlab calculations. The result of the final concept was succeeded. The machine's movement and the influencing forces on the reflector mimic the performed test that was made at the beginning of the project. Improvements that can be done is to change to a more powerful motor to achieve a more constant speed or a flywheel to reduce the strain on the motor. For further work RECCO can program a switch that turns off the motor when the number of cycles are achieved.

Full textAbstract:
Kravhantering vid agil mjukvaruutveckling är en utmaning som allt fler företag ställs inför.Prototyper, modeller som liknar tilltänkta slutprodukter, kan användas för att inhämtaviktig information om det som ska utvecklas. För att beskriva hur lik en prototyp är dentilltänkta slutprodukten används begreppet verklighetsfaktor. Studiens syfte är dels attöka kunskapen kring prototypanvändning i agil mjukvaruutveckling, dels att undersökavilken effekt en prototyps verklighetsfaktor har då prototyper används i diskussioner inomkravhantering. En fallstudie görs på företaget Exsitec där personal intervjuas angående prototypanvändning i mjukvaruprojekt. Två prototyper utvecklas sedan med låg respekti-ve hög verklighetsfaktor och används som diskussionsunderlag i intervjuer. Studien visar att användning av prototyper i mjukvaruprojekt kan bidra till ökat förtroende hos kun-der, förbättrad kommunikation med kunder och kan förenkla att uppnå konsensus mellan olika intressenter. Vidare kan de, beroende av hur de används, bidra till helhetsbilden avprodukten och fungera som dokumentation. Studien påvisar även några, om än subtila, skillnader i den information som samlas in med hjälp av prototyper med låg respekti-ve hög verklighetsfaktor. Hög verklighetsfaktor tycks medföra att fler krav samlas in, men göra respondenter mindre benägna att vilja komma med förslag på mer omfattandeförändringar.Requirements Engineering (RE) in Agile Software Development (ASD) is a challenge thatmany face and several techniques exist when doing so. One such technique is prototyping, when a model of a product is used to gather important information in software develop-ment. To describe how much a prototype resembles the product the notion of fidelity is used. The aim of this study is to contribute to research regarding prototyping in ASD,and to examine the effect of a prototype’s fidelity when using prototypes in discussionsduring RE. A case study is performed at the company Exsitec where staff are interviewedregarding prototyping in software development. Thereafter, two prototypes of low andhigh fidelity are developed and used in interviews as a basis for discussion. Based on thisstudy, the use of prototypes in software projects can help customers trust the process,improve communication with customers, and facilitate when trying to reach consensusamong different stakeholders. Furthermore, depending on how they are used, prototypescan contribute to understanding the big picture of the requirements and can also serve asdocumentation. The study also shows some, albeit subtle, differences in the informationcollected using prototypes with low and high fidelity. The use of a high fidelity prototypeseems to generate more requirements, but makes interviewees less likely to come up withlarger, more comprehensive requirement changes.

Full textAbstract:
Today we use an obsolete way of handling information regarding which student and/or teacher is attending which class/lab/seminar, attendance is written down on a piece of paper and collected so that an administrator can manually enter this information to some data processing system. This method is far from optimal and demands a lot of time and resources from administrators, teachers, and students. Correct gathering of attendance is important since it is required for specific parts of some courses. We propose to automate the collection of this attendance data, thus enabling students and teachers to simply swipe their NFC-enabled KTH access card in order to enter their name on an attendance list. This will be achieved by creating an application that adds a student to an attendance list by reading information using a NFC/RFID reader and mapping the card’s UID to a KTHID (a locally unique identifier used within the university) using a database. The resulting attendance list should be formatted in such a fashion that it can easily be uploaded to systems such as KTH Social and Daisy. Ideally these systems will be extended so that instructors/teachers can use this attendance list to automatically create the appropriate entries in these systems to record the student’s participation in the indicated activity – in the process avoiding a lot of manual labor and improving the accuracy of the process. An additional problem is that there is currently no unified system that connects the KTH access card database (BRAVIDA) to the KTH LDAP database (which stores information about KTH students, faculty, and staff). This means that each student’s access card UID must manually be added to a database together with the student’s KTHID. However, once this database entry has been made, we can then map from a card number to a KTHID (or the reverse). The purpose behind and expected result of this thesis is a functional prototype of an application that creates an attendance list by reading data from the student or teacher’s access cards using a NFC reader. This will hopefully stimulate further digitalization in KTH and also encourage more courses to utilize such access card based attendance lists. The result should be less manual effort by students, faculty, and staff, as well as more accurate and timely filing of attendance information for courses.I dagsläget använder vi en föråldrad metod för att hantera information kring vilken student och/eller instruktör som närvarar vid vilken föreläsning/laboration/seminarie, närvaron skrivs ner på en bit papper som samlas ihop och skickas till en administratör som sedan manuellt får mata in den här informationen i de olika databehandlingssystemen. Denna metod är långtifrån optimal och kräver en massa tid och resurser från administratörer, lärare och elever. Att den insamlade informationen är korrekt är viktig eftersom den är ett krav vid vissa kurser. Vårt förslag är att insamlingen av närvaroinformation automatiseras, genom att studenter och lärare enkelt kan dra sina KTH access kort för att mata in sitt namn på en närvarolista. Detta kommer att genomföras genom utvecklandet av en applikation som lägger till en student i närvarolistan genom att läsa av kort genom en NFC/RFID läsare och mappning av kortens UID till ett KTH användarnamn (användarnamnet är unikt inom KTH) med hjälp av en databas. Närvarolistan som genereras som ett resultat av programmets körning skall vara formaterad på ett sådant sätt att den enkelt kan laddas upp till system som KTH Social och Daisy. Idealt skall applikationen vidareutvecklas så att instruktörer/lärare kan använda närvarolistan till att automatiskt lägga till rätt post i de systemen för att lagra information om studentens närvaro vid en viss aktivitet - med mål att undvika mycket manuell inmatning samt öka noggrannheten kring processen. Ett ytterligare problem är att det i nuläget inte finns något system som kopplar KTH:s databas för accesskort (BRAVIDA) till KTH LDAP databasen (som lagrar information om KTH studenter, fakultet och personal). Detta betyder att varje användares accesskorts UID måste läggas till i en databas manuellt tillsammans med studentens KTH användarnamn. Emellertid är det så att när posten väl är inlagd i databasen, så kan vi mappa mellan accesskorts UID till KTHID(eller motsatsen). Detta examensarbete har resulterat i en fungerande prototyp av en applikation som skapar närvarolistor genom att läsa av data från studenter och lärares accesskort med hjälp av en NFC läsare. Detta kommer förhoppningsvis att stimulera ökad digitalisering inom KTH och dessutom motivera fler kursansvariga att använda accesskortsbaserade listor. Resultatet bör förhoppningsvis bli mindre manuellt arbete för studenter, fakultet och övrig personal samt mera precis och snabbare insamling av närvaroinformation.

Full textAbstract:
Träbyggande har stark historisk förankring i Sverige. För drygt ett sekel sedan sattes ett förbud in mot att bygga hus i fler än två våningar i trä på grund av den ansedda brandrisken materialet medförde. Vid Sveriges inträdande i EU år 1994 togs det gamla beslutet bort och utvecklingen inom träbyggandet för flerbostadshus har därefter fått en rejäl uppgång. Utvecklingen har medfört ett modernare sätt att bygga, från att tidigare ha byggt allt på byggarbetsplatsen till montage av prefabricerade väggmoduler. Med detta tillvägagångssätt har byggandet både kunnat säkra en högre kvalitet samt effektiviserats. Ett företag som arbetar med prefabricerade väggblock är Isotimber. Deras väggblock är unik på det sätt att de endast innehåller trä, för att uppnå ett högre isolervärde har råvaran trä kombinerats med urfrästa luftspalter. Isotimber har haft en önskan att utveckla sin produkt eftersom de fastskruvade kassetterna som bildar ett enhetligt väggblock separerar vid lyft. Lyftpunkterna har placerats genom borrade hål i väggblocken med genomförda lyftstroppar, ett tillvägagångssätt som Isotimber önskat förändra. Tvärkrafterna som uppstått vid lyften har verkat diagonalt mot väggblocken och antal lyftpunkter har varierat. Studien har riktat sig mot att utveckla det befintliga väggblocket samt studera om lyft har gått att utföra på ett annat sätt än i dagsläget. Lyftpunkternas placering har även granskats. Resultatet av produktutvecklingen har lett till att en limträbalk har placerats i överkant av blocken. Det har medfört att lyftpunkter har förflyttats till limträbalken där håltagning för stroppbanden kommer att utföras. Antal lyftpunkter har blivit beroende av väggblockens spännvidd och de tvärkrafter som uppstår vid lyft skall inverka vertikalt mot väggblocken. Resultatet av den nya väggblocksprototypen har krävt dimensionering av limträbalk vid lyftpunkter samt infästningarna mellan väggblock och limträbalk. Väggblockets förändringar har bidragit till ett smidigare montagesystem. Den monterade limträbalken kan även anses ge en mindre nedböjning i väggblocket. Lyftpunkterna har blivit fler med bestämda avståndsintervall för att motverka separationer mellan de ihopskruvade kassetterna i väggblocken.Building with wood has a strong historical anchorage in Sweden. Just over a century ago, a ban was imposed on building houses on more than two floors of wood due to the perceived fire risk caused by the material. At Sweden's accession to the EU in 1994, the old decision was removed and the trend in the construction of wooden houses for multi-family houses has subsequently increased dramatically. The development has resulted in a more modern way of building, from building everything on the construction site to the assembly of prefabricated wall modules. With this approach, construction has been able to ensure a higher quality and efficiency. A company that works with prefabricated wall blocks is Isotimber. Their wall blocks are unique in that they contain only wood, in order to achieve a higher insulation value, the raw material wood has been combined with milled gaps of air. Isotimber has had the desire to develop its product because the screwed cassettes that forms a uniform wall block, separates during the lifts. The lifting points have been placed through drilled holes in the wall blocks with inserted lifting straps, an approach that Isotimber wishes to change. The transverse forces that have occurred during the lift have acted diagonally against the wall blocks and the number of lifting points has varied. The study has been aimed at developing the existing wall block and to study whether lifting could be done in a different way than today. The position of the lifting points has also been examined. The result of product development has led to a laminated wooden beam being placed above the blocks. This has meant that lifting points have been moved to the laminated wooden beam where perforation for the straps will be executed. The number of lifting points has become dependent on the width of the wall blocks, and the transverse forces that arise during lifting must be vertical to the wall blocks. The result of the new wall-block prototype has led to dimensioning of the laminated wooden beam at the lifting points, as well as the connections between the wall block and the laminated wooden beam. The wall block changes have contributed to a smoother mounting system. The laminated wooden beam can also be considered to give a smaller deflection in the wall block. The lifting points have become more at fixed range intervals to counter the separations between the screwed cassettes in the wall blocks.

Į prototipines baltumo ir juodumo konceptų reikšmes (baltas, -a – sniego spalvos, visai šviesus, juodas, -a – visiškai tamsus, kaip anglis) remiasi nemažai metaforinių reikšmių. Šio magistro darbo tikslas – išskirti skirtingas ir bendras baltumo ir juodumo metaforines reikšmes, būdingas lietuvių ir anglų kalboms. Tyrimo medžiagą sudaro lietuvių kalbos tekstyno grožinės literatūros blokas ir anglų kalbos tekstyno medžiaga.
Išanalizavus tekstyno medžiagą nustatyta, jog prototipinės juodo reikšmės: tamsus, neperregimas, tankus, gilus; nešvarus, suteptas; rasė, gymis; rūšies pavadinimas; kava, arbata; metaforinės reikšmės: nešvarus, nedoras; prastas apie maistą (tik lietuvių kalboje); blogis: a) viduje išgyvenamas (emocijos); b) bauginantys, tragiški, nelaimingi įvykiai, su jais sietinos vietos; sunkus, kasdienis; neteisėta veikla, tokios veiklos rezultatai; simbolinės reikšmės: artėjančios nelaimės simbolis; nelaimės pranašai (blogio simboliai); gedulo simbolis.
Tekstyno medžiagos analizė parodė, jog prototipinės balto reikšmės: šviesa; perregimas, bespalvis; švara; tuštuma; rasė, gymis; rūšies... [toliau žr. visą tekstą]Every language has colour terms, but different amount of them depending on extra linguistic features. Linguist B. Berlin and P. Kay analysed dozens of languages and determined that there were only two colour terms (dark and bright) in the first stage of language evolution. Bright is represented by white and dark is represented by black. Many metaphoric meanings are based on prototypical meanings of concepts of whiteness (white – of colour of snow, very bright) and blackness (black – very dark, like coal). The goal of this master thesis is to determine common and different metaphorical meanings of whiteness and blackness characteristic for Lithuanian and English languages. The research material is collected from corpuses of Lithuanian and English languages. The data of the analysis of both concepts showed, blackness and whiteness in most cases are used to identify a feature of colour, i.e. prototypical colour meaning. But it also revealed a number of cases when the colour term does not denote a colour feature, but it is used metaphorically, with objects lacking the colour feature. The analysis has also revealed the importance of the symbolic meaning in the research of the colour concepts. The concept of Blackness in both languages is perceived similarly. Prototypical meanings are the following: dark, lacking light, impenetrable, soiled; used to characterize dark skin pigmentation; certain object in black colour (blackcurrant, black bread and etc.); (coffee or tea) without...

Full textAbstract:
Målet med detta examensarbete har varit att utveckla en app med en algoritm för att mäta rotationshastigheten hos en prototyp för en spirometerlösning till en låg kostnad för smart- telefoner. En förstudie har gjorts av smarttelefoners användbarhet för att mäta hälsotillstånd och vilka alternativa lösningar och algoritmer som finns för att mäta rörelsedetektion. I detta arbete har en app med en algoritm utvecklats för att detektera rörelser och mäta rotations- hastigheten hos spirometerprototypens turbin filmad med en smarttelefonkamera. För att metoden ska fungera är det viktigt att rotationshastigheten understiger hälften av kamerans fps (bilder per sekund). Rotationshastigheten hos turbinen måste därför begränsas och det behövs en kamera som klarar minst 120 fps för att fånga rörelserna i prototypens turbin.Arbetet har resulterat i en fungerande algoritm för att bestämma turbinens rotationshastighet. Den utvecklade algoritmen detekterar topparna i en PPG (photoplethysmogram). För att minska beräkningstiden och för att öka noggrannheten analyserar algoritmen färgintensiteten i ett begränsat område, ett s.k. ROI (Region of Interest) i varje bild. Det finns stora möjligheter att använda denna algoritm för att fortsätta utvecklingen av detta alternativa sätt att utföra spirometritester.The goal with this bachelor thesis was to develop an application with an algorithm to measure the rotation speed of a prototype, as a low-cost solution for measuring spirometry with a smartphone. In a pilot study it was investigated how a smartphone can be used to measure health and what algorithms there are to detect motion in videos. After the pilot study an app with the function to record a video by using the camera of a smartphone and then use an algorithm to detect the rotation speed in the spirometry-prototype’s turbine was developed. To make it work it is important that the rotation speed is low enough so it does not exceed half of the cameras fps. Therefore, to capture the rotation speed of the spirometry-prototype’s turbine the rotation needs to be limited and a smartphone with a camera with at least 120 fps is required.The result of this work is an algorithm that can measure the rotation speed in the spirometry prototype turbine. The algorithm is detecting the peaks in a PPG. To minimize the computation time and to increase the accuracy the algorithm analyses the colour intensity over a ROI in every frame. There is great potential to use this algorithm to further develop this alternative method of measuring spirometry.

En la actualidad las empresas automotrices centran sus esfuerzos en la realización de productos enfocados en el rendimiento y confort y que es ofrecido a los usuarios. Debido a esto, es necesario incluir dispositivos que brinden al usuario la capacidad de configurar estos mismos, y por ende, permitan el control del funcionamiento del dispositivo basado en los requerimientos actuales del operador. Las interfaces Humano-Máquina (HMI) tienen como objetivo capturar como base las indicaciones recibidas por un operador humano el cual ingresa cierto tipo de parámetros al dispositivo y éste realiza acciones como respuestas a los deseos del usuario. Los radios de reproducción de audio implementados en los automóviles tienen como función principal de operación el entretenimiento de los pasajeros a bordo del carro, realizando la reproducción de varios formatos de audio en las bocinas propias del vehículo con la premisa principal de eliminar cualquier tipo de distracción al conductor generada por la operación manual del radio. Para lograr este objetivo, las empresas utilizan varias formas de evaluación del producto con el fin de perfeccionar los sistemas que harán parte de un automóvil teniendo en cuenta la opinión de los posibles usuarios.(cont.) Una de estas técnicas de evaluación utiliza la simulación de prototipos físicos en aplicaciones virtuales, las cuales ofrecen al interesado características similares a las presentadas por los dispositivos en tiempo real. La simulación de autoestéreos permite conocer las respuestas de operación, entregadas por el radio, al realizar procedimientos de selección de modos de reproducción, búsqueda de estaciones de radio o canciones, reconocimiento y reproducción de dispositivos externos de almacenamiento de audio, etc. El uso de la herramienta RapidPLUS como interfaz de simulación permite elaborar aplicaciones compactas que en cierto modo recrean el entorno grafico de la aplicación y el funcionamiento básico del radio. Esta tesis plantea la elaboración de varias aplicaciones virtuales por medio de este software que simulen las operaciones y modos incluidos en el manual de funcionamiento del radio proporcionado por la empresa Volkswagen de México..

Full textAbstract:
Although Set-top-Boxes(STBs) are widely deployed today to connect a media source to a display (traditionally a television set), the market is changing due to the introduction of Internet Protocol Television, Over-the-Top streaming devices, gaming console, home theater Personal Computer, smart TV, etc. There is an evolving concept of a Home Media Center (HMC). This HMC provides consumers with an integrated home media environment and experience. This thesis explores the transition from STBs to HMCs. The specific questions that this thesis project answers are: What will a future HMC look like? What will its functions be? What interfaces and protocols will it use? Who will make these HMCs? How can STB vendors evolve to be HMC vendors or will they simply cease to exist? This thesis project designed and evaluated a hypothetical HMC prototype based upon current technology trends and user expectations. This prototype was used with 68 volunteers to identify and prioritize the most important features that a HMC should provide. Based upon the most important of these features a conceptual HMC prototype is designed to define a HMC product roadmap for 1, 3, and 5 years. This roadmap is used to project the economic impact of HMCs on the current STB industry. This economic analysis considers Sweden as the target market. This thesis could be used by current STB vendors to define their own company specific roadmaps to support their transition to the future HMC market.Aven digitalboxar är spridda i dag för att ansluta en mediakälla till en bildskärm (traditionellt en TV) är marknaden förändras på grund av införandet av Internet Protocol Television, Over-the-Top streaming anordningar, spelkonsol, hem teater Personal Computer, smarta TV osv. Det finns en framväxande begreppet Home Media Center (HMC). Detta HMC ger konsumenterna ett integrerat hem mediemiljö och erfarenhet. Denna avhandling utforskar övergången från digitalboxar till HMC. De specifika frågor som detta examensarbete skall besvara är: Vad kommer en framtida HMC se ut? Hur kommer dess funktioner att bli? Vilka gränssnitt och protokoll kommer den att använda? Vem kommer att göra dessa HMC? Hur kan digitalboxar leverantörer utvecklas vara HMC säljare eller kommer de helt enkelt att upphöra att existera? Detta examensarbete designar och utvärderar en hypotetisk HMC prototyp baserad på nuvarande tekniktrender som användarnas förväntningar studie. Denna prototyp användes med 68 frivilliga att identifiera och prioritera de viktigaste funktionerna som en HMC bör ge. Baserat på de viktigaste av dessa funktioner en konceptuell HMC prototyp kommer att utformas för att definiera en HMC produkt färdplan för en, 3 och 5 år. Färdplanen kommer att användas för att projicera de ekonomiska konsekvenserna av HMC på den aktuella digitalboxar industrin. Denna ekonomiska analysen kommer att överväga Sverige som målgrupp. Denna avhandling kan användas av nuvarande digitalboxar leverantörer för att definiera sina egna företagsspecifika färdplaner för att stödja övergången till den framtida HMC marknaden.

Full textAbstract:
The goal of this thesis project is to improve industrial system testing efficiency. The thesis is mainly focused on the field of telecommunication. Testing is one of the most important steps before selling a product to customers and testing is also an important component of after sale maintenance. The work load for testers can be decreased and more projects could be carried out in parallel, if the testing efficiency can be improved. The thesis project is carried out within the Ericsson Product Development Unit (PDU) Packet Core System Test section. The goal is to improve the system testing efficiency of the Evolved Packet Gateway, as system testing has gradually become one of the bottle necks for the whole product release. Ericsson wants to accelerate its pace in releasing new products to the market and releasing new software to their customers. An initial investigation was made to get a clear view about how the complete system testing procedure is currently carried out and then, an analysis was made based on this information. Ideas were collected for a proposed new implementation and finally a prototype for the most useful ideas was developed and evaluated to show how the system testing efficiency can be improved. Finally, these ideas were proved to be valuable for Ericsson PDU Packet Core System Test section and two of them have been adopted and are already under developing.Målet med detta examensarbete är att förbättra effektiviteten inom industriell systemtestning. Avhandlingen är främst inriktad på området för telekommunikation. Testning är ett av de viktigaste stegen innan försäljning av en produkt till kunder och testning är också en viktig komponent under underhållsfasen. Genom att förbättra effektiviteten i testerna kan arbetsbelastningen för testare minskas och flera projekt genomföras parallellt. Examensarbetet har utförts inom Ericssons produktutvecklingsenhet (PDU) Packet Core, avdelning System Test. Avhandlingens mål är att effektivisera systemtestning av Evolved Packet Gateway (EPG), eftersom systemtest gradvis blivit flaskhalsen för hela produktens release. Ericsson vill påskynda takten som de släpper nya produkter på marknaden och ny mjukvara till sina kunder. En första undersökning gjordes för att få en tydlig bild av hur systemtest utförs för närvarande och därefter, gjordes en analys baserat på denna information. Idéer samlades in för att föreslå en ny implementering och slutligen utvecklades en prototyp av en specifik idé och den harutvärderats för att visa hur effektiviteten hos systemtest kan förbättras. Slutligen, var dessa idéer visade sig vara värdefullt för Ericsson PDU Packet Core System Test avsnitt och två av dem har antagits och håller redan på att utveckla.

Full textAbstract:
En la actualidad, el problema de la vulnerabilidad de la vivienda y la calidad en su diseño y construcción sigue siendo vigente por la continua informalidad en su desarrollo y ejecución. Lo que nos indica que la mayoría de estas nuevas viviendas van a ser autoconstruidas por los habitantes de estas localidades sin ningún tipo de asesoría o referente técnico. Esto se agrava, cuando se considera que los que ejecutaran estas viviendas no cuentan con las habilidades y conocimientos técnicos mínimos para una buena práctica constructiva. Generándose con ello una vulnerabilidad estructural, así como un uso deficiente en su habitabilidad.
La presente tesis tiene como objetivo, desarrollar un prototipo de vivienda social de construcción progresiva para el Cono Norte de Lima. La propuesta destaca que el prototipo de vivienda social de construcción progresiva más adecuada, es la de un diseño de modelo integrado sumamente sencillo y practico en su aplicación, bajo el enfoque, de plantear primero la modulación estructural y luego las demás especialidades; basado en el cumplimiento de los parámetros normativos de la zona, y la normatividad en el diseño de la arquitectura, de estructuras, instalaciones sanitarias e instalaciones eléctricas.
La metodología usada, es de enfoque cualitativo, sustentada, en explorar y describir los hechos, para luego generar perspectivas teóricas de solución, para ello se buscará información a través de fichas de inspección, encuesta de campo, fotografías y análisis planimétrico.
Finalmente, el aporte de esta tesis es determinar el prototipo de vivienda social de construcción progresiva modular en lima, para contribuir especialmente a la solución de la autoconstrucción y sus efectos en la vulnerabilidad y habitabilidad en las viviendas.At present, the problem of housing vulnerability and quality in its design and construction remains in force due to the continuing informality in its development and execution. This indicates that most of these new homes will be self-built by the inhabitants of these locations without any advice or technical reference. This is aggravated, when it is considered that those who run these homes do not have the minimum technical skills and knowledge for a good constructive practice. Generating with it a structural vulnerability, as well as a poor use in its habitability. This thesis aims to develop a prototype of social housing of progressive construction for the Northern Cone of Lima. The proposal emphasizes that the most adequate progressive construction social housing prototype is that of a very simple and practical integrated model design in its application, under the approach, of first proposing structural modulation and then the other specialties; based on the fulfillment of the normative parameters of the area, and the normativity in the design of the specialty of architecture, structures, sanitary installations and electrical installations. The methodology used is of a qualitative, sustained approach, in exploring and describing the facts, and then generating theoretical perspectives of solution, for this information will be sought through inspection sheets, field survey, photographs and planimetric analysis. Finally, the contribution of this thesis is to determine the prototype of modular progressive construction social housing in Lima, to contribute especially to the solution of self- construction and its effects on vulnerability and habitability in homes.

iProspect is a global digital marketing agency and work primarily with search marketing. They were the first search engine marketing agency in the world when the company started up 1996 in Boston, Massachusetts, and the first in Sweden to offer services in search marketing after establishing themselves on the Swedish market the following year. iProspect can be found in the södermalm office in south central Stockholm. They are a comprehensive agency within search and offer everything from search engine optimization and sponsored links to advertising on social media. They’re goal is to lead developments in search marketing and to keep ahead of competition. To do this they must constantly challenge themselves. The market is constantly evolving and new services are offered regularly. This report describes the development of a design document for a mobile application for increased knowledge and for sharing knowledge about a new service from iProspect . The service in question, attribution, is already sold today by iProspect in markets abroad and the ambition is to do so also in Sweden as soon as there are resources in the form of "know-how". The draft design document should evolve to include their employees with increased knowledge of how attribution can be applied as a service. During the execution of this work, interviews, usability tests with prototypes and observations were made and conducted. Based on the methodology and the work process, the results have been analyzed and discussed. Hopefully the application will be of use prior the implementation process of the new service.

This project was carried out using a product development process for Mitab, a furniture manufacturer in Tranås. The company mainly produce products for public spaces. RAL is a chair in their collections and it is designed mainly for public spaces. There is a need to assemble the chairs with each other at different context. The purpose of this project was to develop a link between the chair seats. The main focus of the project was to come up with drawings and pictures that visualizes a solution to link RAL-chairs together. The project started with Mitabs need to join a specific chair model, laterally together. This need generated questions and a product development process was performed to finally result in a production friendly product. Inspiration and knowledge acquired through studying literature, observation of product development at the company, as well as visits to the furniture fair in Älvsjö. Interviews and tests were used in order to gather information about the problem. Several concepts were developed and evaluated together with the company. Combining functionality with a design that is compatible with the chair's design as well as a simple and clear design has been the purpose of this project. The result is a coupling seat that is hidden under the seat, and that is easy to use. The result was a concept of linking chairs together. The coupling is hidden under the chair seat when it is not in use. Plastic and steel was chosen as material and a prototype was produced which shows the form and function of the developed concept. The resulting drawings has led to a prototype. This prototype meets the requirements Mitab has presented at the start of the project. A cost estimate based on the concept note has been submitted and the total production cost of the chair coupling is far below the company's cost requirements. Work that remains is to test the prototype and evaluate the sustainability of the product and to evaluate any load requirements. Further detailed cost estimations should be done to obtain a more accurate pricing.Arbetet har utförts som ett produktutvecklingsprojekt åt möbelföretaget Mitab. Företaget ligger i Tranås och jobbar huvudsakligen med möbeldesign och inredningsprodukter för offentlig miljö. Uppdraget har varit att ta fram ett lösningsförslag på en stolskoppling till en befintlig stolsmodell i företagets sortiment. Arbetets omfattning har innefattat framställning av en produkt från idé till ett färdigt förslag. Målet med examensarbetet var att ta fram ritningar och bilder på en fungerande produktidé som kopplar samman RAL-stolar. Vid projektstart delgav företaget ett behov av att kunna sammanfoga en specifik stolsmodell i sidled. Utifrån detta behov genererades frågeställningar och en produktutvecklingsprocess genomfördes för att slutligen resultera i en produktionsvänlig produkt. Inspiration och kunskap har inhämtats genom att studera litteratur, observation av produktutveckling på företaget samt besök på möbelmässan i Älvsjö. Intervjuer och tester användes för att samla in information om problemet. Flera koncept har utvecklats och utvärderats tillsammans med företaget. Att kombinera funktion med en formgivning som är kompatibel med stolens design samt en enkel och tydlig design har varit ett syfte med detta projekt. Resultatet är en koppling som är dold under stolsitsen och är enkel att använda. Resultatet blev ett koncept för att länka stolar tillsammans. Kopplingen är dold under stolsitsen när den inte används. Plast och stål valdes som material och en prototyp tillverkades som visar formen och funktionen av det utvecklade konceptet. De resulterande ritningarna har medfört att en prototyp har kunnat tas fram. Prototypen uppfyller de krav som Mitab har lagt fram vid examensarbetets projektstart. En kostnadsuppskattning baserad på konceptunderlag redovisas och den sammanlagda tillverkningskostnaden för stolskopplingen ligger långt under företagets kostnadskrav. Arbete som kvarstår är att testa prototypen och vidare undersöka material för att kunna utvärdera hållbarheten i produkten och eventuella belastningskrav. Mer detaljerade kostnadsberäkningar bör genomföras för att få fram en mer exakt prisbild.

Sveriges järnvägsnät utgör en viktig del i landets infrastruktur och transporterar både människor och stora mängder gods. Järnvägsnätet är dock störningskänsligt och då stora delar av infrastrukturen är enkelspårig blir alla fordon som trafikerar samma linje beroende av varandra och en försening på ett tåg resulterar ofta i följdförseningar till övriga tåg på samma linje. Idag sker uppföljning av förseningsorsaker manuellt och ofta lång tid efter att det hänt vilket resulterar i osäkra och opålitliga data. Målet med detta projekt är att utveckla en prototyp för ett rapporteringssystem som skulle kunna implementeras i Sveriges järnvägsnät för att möjliggöra realtidsuppföljning på förseningar som uppstår. Förutom att rapporteringen ska ske i realtid ska även användaren direkt notifieras när en försening uppstår och på så sätt inte själv behöva ha koll på det. Resultatet av projektet var en prototyp som i realtid upptäcker förseningar och då notifierar den berörda användaren om att en försening uppstått, vid vilken station det skett och förseningens omfattning i antal minuter. Användaren har då möjlighet att rapportera orsak till förseningen. Prototypen upptäcker även följdförseningar.The Swedish rail network constitutes an important part of its infrastructure and transports both people and large quantities of goods. Unfortunately, the rail network is susceptible to disruptions since a large amount of the rail network consists of one-track sections. Trains that traffic these sections are dependent on each other. One delay may result in subsequent delays for other trains. The follow-up of causes of delays is today done manually and often weeks after it occurred which may results in uncertain and unreliable data. The goal of the project is to develop a prototype of a reporting system which could be implemented into the Swedish railway network to enable real time monitoring of delays that occurs. The prototype should notify the user when a new delay has occurred. The result of the project was a prototype which in real time detects delays and notifies the affected users that a delay has occurred, at which station it happened and the extent of the delay is presented in minutes. The user then has an opportunity to report cause of delay. The prototype also detects subsequent delays.

Full textAbstract:
The doctoral thesis introduces a study of possibilities for utilization of virtual reality technology in risk analysis and safety of production machines. The main goal of the thesis is to analyse and examine possible means of integrating visualization and interaction techniques of virtual reality into the risk identification process in the early stage of the production machine life cycle. The proposed work provides a methodological approach to the theoretical implementation of these techniques in the definition of dangerous areas of a machine, identification of sources of possible risks and verification of applied measures built-in in the machine structure. A system approach is used for forming and optimizing the introduced methodological procedures. The solution includes the design of the methodology for effective transfer of 3D design data into immersion virtual reality domain. This enables overcoming existing barriers in exploitation of virtual reality technologies in industrial applications. The next section introduces a procedure of implementation of real tools and equipment in immersion virtual reality domain, including an option for detection of collisions between the real tools and virtual objects. Experimental tests confirm its capability of practical utilization. The impact of the final practical contribution is shown by a decrease in the number of accidents during assembly work, due to its appropriate planning and thanks to training of the personnel on a virtual prototype, carried out already before the manufacturing of the actual machine. The result of the presented doctoral thesis contributes to further qualitative improvement of techniques and methods for preventive increase of safety and reliability of developed machines, particularly of machining centres, which will help increase their competitiveness. The properties of the designed procedures are documented and verified on real industrial cases.

Full textAbstract:
Higher demands on database systems have lead to an increased popularity of certain database system types in some niche areas. One such niche area is graph networks, such as social networks or logistics networks. An analysis made on such networks often focus on complex relational patterns that sometimes can not be solved efficiently by traditional relational databases, which has lead to the infusion of some specialized non-relational database systems. Some of the database systems that have seen a surge in popularity in this area are graph database systems. This thesis presents a prototype of a logistics network-related service using a graph database management system called Neo4j, which currently is the most popular graph database management system in use. The logistics network covered by the service is based on existing data from PostNord, Sweden’s biggest provider of logistics solutions, and primarily focuses on customer support and business to business. By creating a prototype of the service this thesis strives to indicate some of the positive and negative aspects of a graph database system, as well as give an indication of how a service using a graph database system could be created. The results indicate that Neo4j is very intuitive and easy to use, which would make it optimal for prototyping and smaller systems, but due to the used evaluation method more research in this area would need to be carried out in order to confirm these conclusions.Högre krav på databassystem har lett till en ökad popularitet för vissa databassystemstyper i några nischområden. Ett sådant nischområde är grafnätverk, såsomsociala nätverk eller logistiknätverk. Analyser på grafnätverk fokuserar ofta påkomplexa relationsmönster som ibland inte kan lösas effektivt av traditionella relationsdatabassystem, vilket har lett till att vissa specialiserade icke-relationella databassystem har blivit populära alternativ. Många av de populära databassystemen inom detta område är grafdatabassystem. Detta arbete presenterar en prototyp av en logistiknätverksrelaterad tjänst som använder sig av ett grafdatabashanteringssystem som heter Neo4j, vilket är det mest använda grafdatabashanteringssystemet. Logistiknätverket som täcks av tjänsten är baserad på existerande data från PostNord, Sveriges ledande leverantör av logistiklösningar, och fokuserar primärt på kundsupport och företagsrelaterad analys. Genom att skapa en prototyp av tjänsten strävar detta arbete efter att uppvisa vissa av de positiva och negativa aspekterna av ett grafdatabashanteringssystem samt att visa hur en tjänst kan skapas genom att använda ett grafdatabashanteringssystem. Resultaten indikerar att Neo4j är väldigt intuitivt och lättanvänt, vilket skulle göra den optimal för prototyping och mindre system, men på grund av den använda evalueringsmetoden så behöver mer forskning inom detta område utföras innan dessa slutsatser kan bekräftas.

Full textAbstract:
Detta examensarbete inom integrerad produktutveckling utfördes vid Högskolan i Skövde i samarbete med Ericsindustrier i Töreboda. Rapporten beskriver metodiken samt processen som utförts i projektet för att uppnå samtliga målsättningar. Syftet bestämdes till en omkonstruktion av en justerskruv placerad i en expanderbar duschstång. Denna duschstång anses vara en viktig del av Ericsindustriers produktsortiment. Grunden till behovet av en omkonstruktion ansågs vara antalet komponenter samt komponenternas montering. Detta krävde att komponentantalet minimerades genom DFx-principer där samma material eftersträvades genom produkten. Försämrad kvalité och hållfasthet definierades som kritiska områden då Ericsindustrier önskade att upprätthålla likvärdig kundnöjdhet samt att produkten skulle hålla för minst 200 N efter omkonstruktionen. Projektets struktur följde en femstegsmodell där designprocessen inleddes med en förstudie. Fokus låg på informationsinsamling, observationer samt kartläggning av nuläget. Genereringsfasen genomsyrades av metodik för att utforska lösningsrymden. Detta innefattade bland annat brainstorming, morfologisk matris samt skissning. I projektet har prototyper haft en stor inverkan då de har fungerat både som generering samt utvärdering av lösningar. De har även agerat som kommunikation till företag samt användare genom hela processen. Iterationer har präglat hela processen för att uppnå en produktutveckling. För att upprätthålla en användarcentrerad design innefattade projektet flertalet användartester. Fötterna till duschstången samt de två rören som bildar själva duschstången identifierades till separata problem. Dessa problem har diskuterats med företaget. Konceptval utfördes efter önskemål från företaget, tester, DFxprinciper samt diskussioner tills det mynnade ut i ett slutgiltigt koncept. Detta koncept uppfyllde de utsatta kraven samt behoven. Konceptet ansågs vara en prisvärd, högkvalitativ samt miljövänlig produkt.This bachelor degree project in integrated product development was carried out at the University of Skövde in collaboration with Ericsindustrier in Töreboda. The report describes the methodology and the process that has been carried out in the project to achieve all the stated objectives. The scope was determined to be a redesign of an adjusting screw placed in an expandable shower rod. The shower rod is considered an important part of Ericsindustrier's product range. The reason for the need of a reconstruction was the number of components and the components assembly. The component number was required to be minimized by using DFx principles where the same material was sought throughout the product. Decreased quality and lower durability were defined as critical areas since Ericsindustrier wanted to maintain customer satisfaction and the product must hold for at least 200 N after the redesign. A five-stage model formed the basis of the project structure where the design process began with a preliminary study. The focus was on information gathering, observations and mapping of the current situation. The generation phase was imbued with methodology to explore solution space. This included, among other things, brainstorming, morphological matrix and sketching. In the project, prototypes had a great impact as they functioned as both generation and evaluation of solutions. They have also acted as communication with companies and users throughout the process. Iterations have characterized the whole process to achieve a product development. In order to maintain a user-centred design, the project included several user tests. The feet of the shower rod and the two pipes that form the shower rod itself were identified as separate problems. These issues have been discussed with the company. Concept selection was carried out according to the wishes of the company, tests, DFx principles and discussions until it ended in a final concept. This concept met the required requirements and needs. Therefore, it was an affordable, high quality and environmentally friendly product.

Istraživanja u okviru disertacije usmerena su na razvoj vakuumskog postupka sušenja voća. Konstruisan je prototip laboratorijske vakuumske sušare i optimizovan proces sušenja višanja i borovnica. U cilju optimizacije procesa sušenja ispitan je uticaj nezavisno promenljivih procesa, temperature i pritiska, na parametre kvaliteta osušenog voća (aktivnost vode, sadržaj ukupnih fenola, ukupnih monomernih antocijana i vitamina C, antioksidativnu aktivnost, promenu boje, teksturu i sposobnost rehidratacije). Proces sušenja optimizovan je korišćenjem metode odzivnih površina (engl. Response Surface Methodology, RSM).Rezultati istraživanja pokazuju da tehnika sušenja voća u vakuumu daje odlične rezultate u pogledu očuvanja visokovrednih komponenata voća i ima perspektivu za širu primenu u zanatskim i poluindustrijskim postrojenjima.Research in the framework of the thesis focuses on the development of fruit vacuum-drying process. Laboratory vacuum dryer prototype was constructed. Cherries and blueberries vacuum drying process was optimized. In order to optimize the drying process, the influence of independent variables of the process (temperature and pressure) on the quality parameters of dried fruit (water activity, total phenol content, total monomeric anthocyanins and vitamin C, antioxidant activity, colour change, texture, and rehydration capability) was investigated. The drying process was optimized using Response Surface Methodology (RSM).There is the possibility of application of the results in plants at semi-industrial and industrial level.
