Full textThe mainpart of this thesis is about the developing of a new analysis tool to be used in Zenicor Medical Systems AB ECG-system. The primary task of the system is to simplify the ECG survey for patients who suffers from different kinds of arrythmias, for example heart fibrillation. With this system is it possible for the patients to do their ECG survey by them self at home and then send the signal with their telephone or mobilphone to a server. The equipment used to do the survey is not bigger than you can have it in a pocket and this results in a bigger flexibility for the patient. A doctor can connect to the server and analys the ECG-curve and follow up the patients condition.

Full textDenna rapport beskriver ett examensarbete inom Programmet för Användarinriktad Systemutveckling vid Linköpings universitet, Campus Norrköping. Resultatet är en databasapplikation som är utvecklad specifikt för C.N.S. Systems AB i Linköping.
I uppgiften ingår analys, utformning, realisering, implementering, dokumentation samt i viss mån även förvaltning och drift. Utvecklingsarbetet har skett i nära samarbete med företaget som har tillhandhållit arbetsplatser och datorutrustning.
Applikationen är ett dokumentregistreringssystem där information om företagets interna och externa dokument lagras. Tidigare har motsvarande uppgifter lagrats i Excel. Den färdiga databasapplikationen har främst gjort det lättare att registrera och söka ett dokument vilket också var ett av de uppsatta målen. Själva databasen är utvecklad i Access och gränssnittet i Visual Basic. Kopplingen mellan dessa är skapad med ActiveX Data Objects 2.0 (ADO).
Rapporten ger inledningsvis en närmare presentation av utgångsläge och förutsättningar. Därefter beskrivs teorin bakom det arbetssätt som använts. I resultatdelen presenteras applikationen översiktligt, valda delar lite mer ingående. Och slutligen, i diskussionsavsnittet, görs en subjektiv bedömning av resultatet och utvecklingsarbetet.

Full textThe goal with this research has been to find out how the company Ackebrink AB could renew their system for managing consultants for courses in post-secondary level schools in Sweden. The system is used to keep track of the whole process from the inquiry from a customer for a consultant until the course is finished and invoiced. We first looked at the old existing system to see if it could be extended. The old system was build four years ago and has been patched and added to by different developers between other projects and a large technical debt has been built up. The old system did work with only a few bugs but to keep adding to it was no longer an option for the new requirements, there were to many temporary solutions and hacks implemented to circumvent flaws in the system The next alternative was to find an off-the-shelf solution or solutions with similar functionality to the old system. Before the old system was built the process was managed with the help of different spreadsheets where everything was filled in and updated by hand. It was a simple and cheap solution which worked for a while until it grew to be a unmanageable behemoth. Since then the business has grown even more and there is now too many parameters to keep track of and too many users of the system for it to be possible to go back to without losing efficiency. A commercial CRM system was evaluated too, SugarCRM, and was rejected because the current process of working doesn’t fit the common CRM model of working. The only alternative left now was to build a new system. Different techniques and frameworks were evaluated and the requirements were a system which could be easily maintained and extended, and that the developers in the team had, or could easily get, the competence necessary to develop a sustainable product. PHP and the framework Symfony2 was finally chosen. PHP is a language which all the developers in the team is familiar with and Symfony2 is a modern and stable MVC framework with active developers and an active online community. A new system with similar functionality to the old system, but built in a current framework and in a sustainable way, was developed and deployed replacing the old system.

Full textGotlands Slagteri is a butchery which produces meat and charcuterie. The company is dependent on long term relationships with suppliers as well as customers, and just as in any relationship it is nurtured by tender and care. The purpose of this study is to identify the relationship with the suppliers and see what could be improved upon. In this case, the improvement regards the company’s way of handling information about suppliers, which in turn generate the following questions; does any further information regarding suppliers, valuable enough to be documented exist? How could present information be stored? The information procured attempts to answer what makes suppliers supply to Gotlands Slagteri as well as what the viewpoint of other butcheries is. Via a literature study CRM is proposed as a possible solution and is backed up by a benchmark of what similar companies do (HKScan, KLS, Hälsingestintan). CRM systems turn out to be a recurrent option and could be procured either by buying an already existing product or be developed on your own. The study concludes in there not necessarily being anything new to add as far as information per supplier go, but instead point to the fact that there are some already existing data which potentially could add individual value. Beyond that the study show that CRM could make a strong case as a future feature. The one thing reaming is for Gotlands Slagteri to determine which CRM-system would make the better fit.

Full textÖkningen i komplexitet hos inbyggda system styr utvecklingen av inbyggda språk till högre nivåer. Dessa språk innefattar inte bara traditionella textbaserade språk utan också grafiska programmeringsspråk som G från LabVIEW vilken har utvecklas av National Instrumets och har funnits sedan mitten av 80 ‐ talet. Dock så har sedan 2004 modulerna LabVIEW SDK och LabVIEW for ARM funnits och dessa har öppnat möjligheten att använda G till inbyggd programmering. Detta examensarbete beskriver hur LabVIEW for ARM kompilerar G till C och sen hur C flashas till mikroprocessorn. Arbetet tar även upp för ‐ och nackdelar med att använda G i inbyggda system. Slutstatsen är att G är mycket användbar för användare utan erfarenhet av inbyggda system som vill utveckla sina ideér. För användare som har erfarenhet så borde en tid/kostnads analys genomföras för att se om G är mer kostnadseffektiv. Nackdelarna är att LabVIEW SDK bara kan användas med 32 bitars processorer och LabVIEW for ARM är ännu mer specifik då de bara kan användas med mikorprocessorer som har ARM arkitektur. En annan nackdel är att om man väljer att använda en microprocessor som inte stöds av National Instruments så måste en struktur skapas först, dock så beskriver denna rapport i detalj hur en sådan struktur kan utvecklas.

Full textIn today's society there are embedded systems in almost everything from toasters to space rockets. In order to meet users’ ever-increasing demands for performance and functionality, the hardware of these systems must be utilized optimally. This can be done by designing hardware specifically for the task, or to use a more general hardware running customizable software. In many cases it may be suitable, and in some cases even necessary, to mix these methods to solve a given task. For example, a powerful processor could be complemented with special designed hardware, called an accelerator, to solve parts of the problem faster. The overall system performance can thus be increased by the use of the accelerators. One problem with this solution is that the connection between the processor and the accelerator may form a bottleneck. One way to reduce the effects of this bottleneck is to tightly integrate programmable logic (FPGA, Field Programmable Gate Array) and a processor on the same chip. This tight integration makes it possible to simplify and speed up the communication between the two units. For example, image processing could be accelerated in the FPGA and the result could then be used in some software application in the processor. This report describes how the work was carried out during this thesis. The main goal of the thesis was to study how a specific product prototype could be implemented using a Zynq-7000 based development board. The focus of this work was to study how the internal communication should be implemented, and there by how the solution should be partitioned between the software and hardware in Zynq-7000. The intended product was a system for image recognition of fruits or vegetables for use in a grocery store. During the work we used a Zynq-7000 based development board called ZedBoard to try our implementations.

Full textIn this work, a system is being developed with the purpose of counting people. The system is intended for use in meeting rooms for up to ten persons and utilizes infrared technique using thermopile arrays. For this work, three different sensor have been used for evaluation. A Panasonic Grid-EYE with a resolution of 8×8 and a Field of View (FoV) of 60°×60°, and two Heimann 32×32d sensors, both having a resolution of 32×32, but with the FoV 90°×90° and 105°×105° respectively. The system has been programmed using the microcontroller STM32L476RG, and with the programming language C. In this system, two methods for people counting has been implemented. The first method compares the total change in temperature of a room in relation to when the room is empty and the other method uses image processing methods, such as interpolation, filtering and area calculations. The sensors are also being evaluated individually, based on characteristics such as accuracy, current consumption and implementation cost. To graphically display the temperature values of the sensors, scripts has been made for MATLAB that uses information sent by the microcontroller. The sensor which seem to be best suited for counting people is the Heimann 32×32d with the FoV 105°×105°. The main advantage of this sensor is its wider FoV, covering a larger area, and its higher resolution, which overall yields a higher accuracy when counting people. However, this sensor requires more complex and time-consuming calculations when processing data than the Grid-EYE. Still, these differences are marginal where the accuracy and the larger detectable area for the HTPA outweighs its disadvantages. The experimental results shows that the Heimann sensor with 105°×105° FoV can achieve an accuracy of ≈98.3 % measuring at a height of 2.45 m. At this height, the detectable area for the sensor is ≈39.1 m2 and is being able to count up to at least 4 persons. As for the Grid-EYE and with the same scenario, the accuracy has not been determined, but has a detectable area of ≈7.7 m2 and is estimated being able to count up to a maximum of 4 persons.

Full textThe aim of this master thesis has been to investigate the possibilities made available with the introduction of user awareness and network capabilities to an ordinary wall socket. This is done by the usage of wireless network construction and Smartphones for control of said network. A preliminary investigation was performed regarding the possible gains of reducing standby power consumption in households. The investigation concluded that standby power consumption stands for an unnecessary high part of the total energy consumption of a modern household. A prototype with the purpose of evaluating the feasibility and use of user aware, controllable and networked power sockets has been designed and constructed. An application using Symbian C++ deployed on a Smartphone has been developed for control and configuration of the network. The information network is based on Bluetooth technology. The functionality of the finished prototype shows that the proposed concept is fully realizable but that the Bluetooth technology has some inherent limits that need to be worked around in order to achieve satisfying network performance.

Full textPower Challenge is a company located in the university town of Linköping. Their main business is development of games. They recently merged with a company called Manager Zone. About one year ago Power Challenge had only about five employees. Today there are more than fifty people working there. The company has developed a football game called Power Soccer. Apart from constantly improving that game, they are also developing a car game. The purpose with this study was to find a method to make the recruitment of new users to Power Soccer more efficient. The method that is used today on the website is just a simple one were the users invite their friends by email. A few alternative methods were investigated and a solution was comprised. To get a better picture of the market, a research was done of all the competitors. They were analyzed to see how they had solved the problem with effective user recruitment. Some social networks were also analyzed. This was done, because they have grown exponentially in a very short time. User interviews were made with help from independent test persons. The design and usability of the new user recruitment system was evaluated. Even though the new system is more advanced, the simplicity should be maintained. When the new recruitment system was implemented, statistics were collected and then compared with the old system. The parameters compared were the average number of mail sent on each day and the maximum number of mails sent out during any day. The result was not quite as expected. The numbers of mails sent out during one day increased significantly. On the other hand the average numbers of mails sent per month, were leveled or had decreased a bit. Due to lack of time, one of the contribution causes to this result was the implementation of a bonus system. This is something that should be done in the future to help increase the number of new players.

Full textSyftet med detta projekt var att vidareutveckla och färdigställa en quadrokopter som byggts i en tidigare projektkurs på KTH, för att den sedan skulle kunna användas i demonstrations- och undervisningssyften på skolan. Quadrokoptern var från början hårdvarumässigt färdigbyggd och viss funktionalitet fanns implementerad men det fanns inget system för automatisk stabilisering. Det främsta målet med projektet var att implementera ett sådant system, och att kombinera det med tidigare funktionalitet för att göra quadrokoptern manöver- och flygbar. För att skapa en fungerande och stabil grund har flera grundläggande mjukvarufinesser implementerats, och därpå ytterligare mjukvara för att förbättra säkerheten, stabiliteten och funktionaliteten. Det viktigaste har att göra med reglersystemet som ansvarar för att omvandla sensor- och styrsignaler till lämpliga motorvärden. Denna rapport beskriver dessa tekniska problem samt de lösningsmetoder och lösningar vi kommit fram till, och analyserar det slutliga systemets egenskaper.

Full textThe purpose of this report is to map the Scania Production System (SPS), how it was motivated and implemented within Scania's organization, as well as linking previous reforms with SPS. We want to find out how Scania managed to create its own customized production system that proved being successful and how it was introduced throughout the organization. SPS is a result of Toyota and their Toyota Production System (TPS) following a close collaboration between Scania and Toyota since the early 1990s. Scania's values, principles and priorities are described by SPS and have proven to be one of the company's competitive advantages through increased efficiency and productivity in production. TPS received much inspiration from the earlier reforms of Taylorism and Fordism from the rationalization movement. This through Taylor's ideas about standardization and Ford's running band principle. Toyota was also one of the first to design and apply the logistics theory’s Total Quality Management, Lean Production and Just-In-Time in its production system. Reforms used and well known in many companies, not least Scania and SPS. The report fulfilled its purpose through interviews and analysis of conceptual literature to find that there is a red thread within the company and that there is a clear link between SPS and previous reforms. In conclusion, we also managed to analyse and draw conclusions about how the SPS was designed, motivated and implemented. The design of SPS was achieved through close collaboration between Scania and Toyota wires, which enabled Scania to inspire and adapt the system to Scania's culture. The way in which SPS was motivated and implanted preceded a management process that Scania applied to within the organization. The solution came to be decisive for the future, leadership. A new way of thinking was applied throughout the business, which has proved to be successful.

Full textThis student thesis is carried out togheter with Ålö AB which manufactures front loaders under the Quicke brand and intents to evaluate a system that calculates vehicle incline. The system should prioritize low cost and must use electronics that is classified for vehicle use (AEC-Q100). This thesis deals with selecting components, sensors and motivations of the selected components, theory of sensor signal conditioning in noisy environments and its implementation. Two sensors where selected that was deemed suitable for evaluation. The first was a 3-axis accelerometer for which a proprietary 2D-positioning algorithm was used to calculate incline. The second sensor that was chosen was a 6-axis IMU that was implemented using sensor fusion with a Kalman filter which was realized with an available software library. The system hardware was implemented with a custom PCB. The system was tested and evaluated stationary and, on a vehicle, along with a reference sensor to give an indication of how the sensors and their respective algorithms performed in both ideal and a real conditions. The stationary tests showed that both solutions perform well regarding outputting incline close to the actual angle. The reliability of the vehicle tests can be improved and as the results they yielded are not of high enough quality to draw conclusions from them. This leads to a recommendation of further testing and evaluation of both solutions.

Full textINVID Jönköping AB is an IT-consultant company. They are a part of the INVID-group that employ about 140 people and are represented in ten different locations in Sweden. INVIDs business areas include development and customization of web applications. The company has been developing a web publishing tool, INVID Publisher.NET. Small- and medium sized companies are offered hosting of a complete web portal/platform with Content Management System/Customer Relationship Management (CMS/CRM) functionality. Customers can manage the content published on web pages. They can choose among a set of templates were there are modules for example text/html and news. To find the right template for the purpose can be a difficult task for the customer.
The purpose of our report is to an answer two main questions:
• How to develop modules for DotNetNuke?
• What is the foundation for the architecture and structure of DotNetNuke?
Our goal was to create modules with the programming language VB.NET and server technology ASP.NET. We would take advantage of the DotNetNuke web application framework for developing modules that offer the customer a way to easily and effectively build new web pages with INVID Publisher .NET. The starting point for the module we have developed is based on analysis of former existing module that INVID AB was not comfortable with. We analysed and discussed the problems that the old module constituted. During the development of the module we also received feedback on our work from our tutor on INVID and other members of the development team.
Our work has lead to a template module were the customer can create new web pages based on templates and also create new templates. INVID and we also consider our module to be graphically well designed.
In the future it’s possible to further develop our module to a great extent because we have followed the principles of DotNetNuke and have written program code that is object-oriented, reusable, and extensible and is based on good programming principles and prominent design patterns.
INVID Jönköping AB är ett IT-konsult bolag. De ingår i INVID-gruppen som totalt sysselsätter drygt 140 personer och finns representerade på tio orter i Sverige. De är verksamma inom ett flertal IT-områden, däribland utveckling och anpassning av webbapplikationer. Företaget har under en tid arbetat med att utveckla ett webbpubliceringsverktyg, INVID Publisher.NET. Små- och medelstora- företag erbjuds en komplett webbportalplattform med Content Management System/Customer Relationship Management (CMS/CRM) funktionalitet sammankopplat med webbhotelltjänster som företaget erbjuder. Kunder har möjlighet att själva påverka det innehåll som finns publicerat på webbsidor. De kan välja bland ett antal mallar där det finns moduler för bl.a. text/bild och nyheter. Att hitta rätt mall för ändamålet kan dock vara svårt för kunden.
Vårt examensarbetes frågeställningar var följande:
• Hur utvecklar man en modul för DotNetNuke?
• Vad ligger till grund för DotNetNukes arkitektur och uppbyggnad?
Vårt mål var att skapa en eller flera moduler med programmeringsspråket VB.NET och servertekniken ASP.NET. Vi avsedde också att lära oss webbapplikationsramverket DotNetNuke för att bygga modul(er) som erbjuder kunden att enkelt och effektivt bygga nya sidor i INVID Publisher .NET. Utgångspunkten för den modul som vi utvecklade bygger på analyser av tidigare existerande mallmodul som företaget (INVID AB) inte var nöjda med. Vi analyserade och diskuterade de problem som den gamla modulen medförde. Under utvecklingens gång fick vi feedback på vårt arbete från vår handledare på företaget och andra personer från utvecklingsavdelningen.
Examensarbetet har resulterat i en fungerande mallmodul där kunden kan med lätthet skapa nya sidor utifrån mallar och även skapa nya mallar. Uppdragsgivaren och vi anser att modulen som utvecklats är mycket grafiskt väldesignad.
I framtiden kan modulen vidareutvecklas framgångsfullt bl.a. tack vare att vi i vårt utvecklingsarbete har följt DotNetNuke-ramverket och dess principer strikt. Vi har även skrivit kod som bl.a. karakteriseras av att den är objektorienterad, återanvändbar, utbyggbar och bygger på goda programmeringsprinciper och framstående designmönster.

Full textSoftware in computers control many important functions in today's society and are widely used for communication but also to control equipment. For the software to work reliably it needs to be built correctly and tested extensively. To achieve reliability, a build server can be used to automatically build and test the software. This report describes how a prototype of a monitoring system for the build servers was created. The system will be monitored by a monitoring service that retrieves information from a build server using the CruiseControl.NET [10] software. The information gathered by the monitoring service will be presented on a web portal. The information retrieved from build the server goes from a high level of abstraction down to the smallest detail that is based on the log files from the build server, for example, information about compilation errors. The development of the monitoring system has been focused on making it possible to use cloud services and thus not restrict where a build server is located. One of the cloud services used is the Service Bus Relay [27] that handles the communication between a monitoring service and the web portal. The web portal is developed to be responsive [34] and provide support for mobile devices which give the user the freedom to visit the web portal from whatever device. The web portal uses a database to store information which enables monitoring of multiple build servers. A well-developed user management system is used on the web portal which provides administrators with an effective tool for user management. There have been several lessons learned, including the discovery of a bug in the Microsoft implementation of message handling in the Service Bus Relay.

Full textIn industrial control systems PID-control remains the prevalent strategy, also for processes that would benefit from model based control. The purpose of this thesis is to evaluate whether model based control can be readily implemented in an industrial control system. To this end a simulated surge tank with a simulated industrial control system is studied. For evaluation two scenarios with specified objectives are selected.
Following a review of LQR and versions of MPC, Predictive Functional Control (PFC) is considered the most suitable for implementation. PFC is a form of MPC developed with industrial applications in mind and therefore has several advantages for implementation in an industrial control system. Controllers for the surge tank-system are developed and implemented in the control system.
Basic analysis of stability, sensitivity and robustness suggests that PFC has some advantages that might be important in a non-simulated implementation. Compared with PID-controllers adjusted for control performance, PFC does not show any notable improvements in performance.
In conclusion, it is possible to implement model based control in an industrial control system and with PFC the implementation is considered easy.

Full textDetta projekt syftar till att undersöka relevansen av att använda UML som stöd vid småskalig utveckling av ett inbyggt system. Detta görs genom att UML används under det initiala skedet av vidareutvecklingen av Telfafill AB:s huvudprodukt Telfafill. Denna produkt är en fyllningsmaskin och målet med vidareutvecklingen är att separera användargränssnittet från styrenheten, och därmed skapa en mer flexibel produkt. Utöver detta fanns önskemålet att ytterligare funktionsändringar och tillföranden undersöks inom examensarbetet. Vidareutvecklingen av Telfafill kom, i detta projekt, så långt som till en kravspecifikation över det önskade systemet och kontakt med potentiella legoutvecklare. Konstruktion av någon prototyp av produkten har vid projektslut inte påbörjats. I rapporten redovisas kravspecifikationen och arbetet med funktionsutveckling, kommunikationsutvärdering och design som lett fram till denna. Vidare redovisas anledningar till varför prototyputveckling valdes att inte genomföras inom projektet. UML har använts via verktygen ArgoUML och Rhapsody in J. Arbetet inleddes med hjälp av ArgoUML men detta verktyg övergavs till förmån för Rhapsody in J. Denna övergång skedde eftersom Rhapsody framför allt erbjöd möjligheter till simulering, men även, visade det sig, var enklare att arbeta i ur de flesta synvinklar. Den aspekt av utvecklingen som UML främst har stött, har varit verifiering av de krav som tagits fram. Genom att systemet har modellerats, har kravkonflikter och dåliga formuleringar kunnat undgås i vad som uppfattas som större utsträckning än utan motsvarande modellering. Vidare har UML varit till hjälp för att öka förståelsen av och insikten i systemets uppbyggnad och funktion. Den största nackdelen med modelleringen har varit att det tagit lång tid att lära in verktygen och UML:s uppbyggnad, mer än vad som kan anses motiverat för ett projekt i denna storleksordning. Som slutsats dras att detta exempel har visat att UML kan vara väl värt att använda som stöd vid småskalig utveckling av inbyggda system. Detta dock under förutsättningen att de som arbetar med utvecklingen inte behöver genomgå långtgående utbildningar för att klara UML och det verktyg som finns och att modellens ”grad av kompletthet” anpassas till det specifika utvecklingsprojektet.

Full textThe food consumption in the Swedish households has a negative effect on the climate. This is partly due to the food production through commercial agriculture which uses large amounts of water, pesticides, and fertilizers. To make food the production more sustainable it requires alternative sources of food production. One solution could be an aquaponic system that is designed to be integrated in households that Habitat On Mother Earth is developing. In aquaponic systems hydroponics and aquaponics is combined. HOME’s system will be design as a tall cabinet with the fish tank at the bottom and the cultivation cabinet located above. In the cultivation cabinet there are four cultivation boxes The purpose of this work is to develop the cultivation boxes in the aquaponic system in a way that makes it as easy and maintenance-free as possible for the client to use.To find a possible concept for the cultivation box, methods are used for concept generation and concept selection. The selected concept is then further developed by using DFM methods to reduce the manufacturing cost and select components for the design. Finally, a CAD modelling of the concept, material selection and an analysis using the finite element method is done.The work results in a developed concept for the design of the cultivation box. A 3D model, a drawing of the cultivation box, choice of components and materials and calculations for the strength of the contruction have also been made.

Full textModern medication allows patients to be treated more efficiently if taken properly.When patients themselves are responsible for their medication, it can be wronglydosed or forgotten, which changes the conditions for its effects. Forgetfulness combinedwith impaired senses make it difficult for the patient to take care of his medication.The solution to this problem today is increased home care, where healthcare professionalshelp patients to take the right medication at the right time. A technical solutioncan be an embedded system that reminds the patient, saves missed dosages, and canprovide more information to doctors who can make more informed decisions for furthercare.The results show that a pill dispenser can be used to remind patients to take their medicationand send missed dosages with near field communication. As a microcontroller,a STM32 Nucleo was used, with a state machine as software solution. In further studies,a real-time operating system can be used. The system was programmed with Arduino'sdevelopment environment, but an alternative is IAR. The prototype of the projectcould achieve the specifications battery life with most modules, except to thesound module used. To achieve this result, two theoretical extremes were created inwhich the prototype was tested.The pill dispenser can lead to reduced waste of pills and a lower cost, as fewer homevisits are required. In addition, this results in increased independence for the patient.These factors cause the pill dispenser to contribute to increased sustainable development.

Full textDevelopment and construction of an electronic Breakout box is the main work for this thesis. The box is a part of a test system for the component Fuel Flow Transmitter and should convert signals to be suitable for a frequency counter. A previously constructed Breakoutbox for this purpose is being old and needed to be recreated. So SAAB Aerotech, Aircraft services, the company for the thesis work wanted to construct a new, more sustainable Breakoutbox adapted to a more modern technology. The signals to the box comes from the transmitter and should be converted to suitable signals for a frequency counter so it can show pulse and time difference between the signals. Both a digital and an analog approach for this purpose have been examined in the work. The result was that the analog solution worked better because the conversion could be performed with OP-amplifier instead of algorithms in a microprocessor. Many problems occured in this thesis work that wasn’t included in the beginning so the most important property proved to be the ability to solve this problems. The Breakout box finally met the requirements from the specification and will in the future be used instead of the old Breakout box as a component in the test system for the Fuel Flow Transmitter.
Det här arbetet handlar om att utveckla och konstruera en elektronisk Breakoutbox som används vid tester av bränslekomponenten Fuel Flow Transmitter. En tidigare konstruerad Breakoutbox för detta ändamål började bli gammal och behövde förnyas. SAAB Aerotech avdelning Aircraft Services, som examensarbetet utfördes åt, ville därför konstruera en ny, mer hållbar Breakoutbox som är anpassad till en modernare teknologi. Insignalerna till boxen kommer från transmittern och ska omvandlas så att en frekvensräknare kan visa pulstid samt tidsdifferens mellan dem. Både ett digitalt och ett analogt tillvägagångssätt för att omvandla signalerna har undersökts under arbetets gång. Resultatet blev att den analoga lösningen fungerade bättre för detta ändamål då omvandlingen kunde utföras med OP-förstärkare istället för algoritmer i en mikroprocessor. Den viktigaste egenskapen i arbetet visade sig vara problemlösning då många problem dök upp under arbetets gång som inte var medräknade från början. Breakoutboxen uppfyllde till slut de krav som fastställdes från början. Boxen kommer i fortsättningen att användas istället för den gamla Breakoutboxen som en komponent i bränsletestkedjan för Fuel Flow Transmittern.

Full textToday there exists many messaging applications and new ones are released almost daily. However, there are not as many messaging applications where both the client application and the server application are open source and can be self hosted. These messaging applications are good at solving the problem that many, up to several million people can communicate with each other. However, there is a smaller more focused use case with a messaging system consisting of only one message flow, where all messages are visible to all devices. This smaller use case means that less metadata is required. Uses for such a messaging system may be to receive notifications from servers or to take personal notes. The message system is synchronized between all devices. The goal of this project is to create an End-to-End encrypted messaging system that provides authentication, data integrity and confidentiality. Research has been investigated regarding weaknesses in some encryption techniques, these weaknesses have been taken into account when creating the messaging system. The purpose why this messaging system needs to be created is because an existing system that meets certain essential requirements for maintaining maximum personal integrity is missing. A prototype has been created that consists of a server application and a graphical computer application. Messages sent in the messaging system are End-to-End encrypted. Communication between clients and the server is also encrypted and authenticated.

Full textI dagsläget är öppna kontorslandskap vanligt förekommande hos företag. Det finns avskilda platser i form av grupp- och mötesrum, dessa är dock allt som oftast begränsade till antal. Att inte kunna boka dessa rum vid behov leder till svårigheter att planera till exempel kundmöten. Problemet att kunna boka ett avskilt rum vid behov finns även inom skolvärlden. På Kungliga Tekniska Högskolan (KTH) i Kista, skolan för information och kommuniktionsteknik, finns det ett antal grupprum där inga av dem är bokningsbara. Det har tidigare funnits bokningsbara grupprum i biblioteket och i andra delar av skolan men idag saknas ett sådant system på grund av nya lokaler. Detta resulterar i att studenter inte kan planera sina studier på ett effektivt sätt då de inte vet om de har en lämplig studieplats mellan föreläsningar. Därför finns det ett stort behov av ett system där studenterna kan boka grupprummen. Uppsatsen dokumenterar utvecklingen av en prototyp ett bokningssystem för grupprum som gjorts med hjälp av HTML, PHP, PostgreSQL, JavaScript och Ajax. Arbetet beskriver även de arbetsmetoder som använts under arbetets gång. Uppsatsen inkluderar en undersökning av bokningssystem som finns idag. Som datainsamlingsmetod har även intervjuer av studenter använts. Utvärderingen av bokningssystemen som finns idag tillsammans med resultatet av intervjuerna gav en indikation om vad som krävs av bokningssystemets användargränssnitt och funktionalitet. Arbetet resulterade i en prototyp av bokningssystemet där användaren kan se vilka grupprum som är lediga, boka grupprum, kvittera bokningar och ta bort bokningar. Prototypen använder en databas som modellerats och implementerats. En evaluering av prototypen resulterade i vad som kan förbättras i ett framtida arbete.

Full textMore and more people are dependent on medication for their survival. These are mainly found in older age groups. Many of these are medicated daily and the burden of medication is noticeable. Because of their problems, enormous stress is associated with medication because it is particularly difficult to remember when it is to be taken, which dose, but also which medicine. Some need to take medicine as often as eight times in one day.These people are treated by doctors. Doctors assess the effectiveness of medication based on the patient's ability and willingness to recall accurate information regarding their compliance with medication. All too often, the patient recalls wrongful information.We have been given the task of further developing a prototype for a "smart" pillbox whose goal is to improve the patient's experience in medication and give the doctor a reliable and safe way to follow the patients' compliance with medication.We have further developed a previous prototype by creating a new prototype that implements all the desired features on a customized circuit board.The advantages of a specially developed circuit board prototype against a modular prototype are investigated regarding size reduction, energy efficiency and cost efficiency.A suitable approach for developing a circuit board prototype, the results of the investigation and recommendations for further development are discussed and presented in the report.A circuit board prototype according to the stated specifications was successfully developed in the specified timeframe. The investigation showed that greater sizereduction, energy-efficiency and cost-efficiency were possible to achieve.

Full textThule Sweden AB utvecklar, tillverkar och marknadsför kompletta och funktionella lasthållarsystem för bilar. De erbjuder en mycket stor bredd av olika lasthållare till över 1500 bilmodeller. De tillverkar lasthållare som cykelhållare, boxar, skidhållare, hållare för vattensport och andra tillbehör. För att en bil skall kunna bära en takbox måste det tillverkas en lasthållare som placeras mellan biltaket och takboxen. En del i denna lasthållare kallas för takbleck och dess form tas fram med en speciell takskanner vilken analyserar biltakets form vid kanterna.
Till detta har en mjukvara tagits fram som Thule kan använda för att söka/lägga till/redigera takbleck, istället för att manuellt söka i en pärm bland 700 olika ritningar. Programvaran var först utvecklad i Microsoft® Visual Studio 2003 (.NET Framework 1.1), men på senare tid omarbetad från grunden i den nyare utvecklingsmiljön Microsoft® Visual Studio 2005 (.NET Framework 2.0).
Innan programmeringen av mjukvaran sattes igång utformades en kravspecifikation från Thule om vad de ville ha för funktioner i programmet. Denna kravspecifikation har under utvecklingens tid ändrats, både under de möten som hållits och på en speciell webbplats som skapats för återkoppling av programmet (”TBS Felhanterings-center”), i form av buggar/ändringar/annat.
Förutom en avdelning i rapporten som behandlar hur denna programvara är uppbyggd, vilka problem som uppstod och hur de löstes, finns även teoretisk information om databaser, XML och andra teknologier.
Resultatet av projektet blev en applikation för hantering av takbleck som kan användas ute i fält (hos kund) utan uppkoppling mot en gemensam databas hos företaget (mot vilken all information synkroniseras). All information som läggs till/redigeras sparas på användarens lokala dator i form av XML som sedan kan synkroniseras mot den gemensamma server-databasen på företaget.
Thule Sweden AB develop, manufacture, and market complete and functional load carriers for cars. They provide a large amount of different load carriers for over 1500 car models. They also manufacture carriers such as bike carriers, roof boxes, ski carriers and water sport carriers. To be able to put a roof carrier on a car, a load carrier must be manufactured and be placed between the car roof and the roof carrier.
We have developed software that the group of workers at Thule can use to search/add/edit brackets, instead of manually search in a folder containing over 700 drawings. The program was first developed in Microsoft Visual Studio 2003 (.NET Framework 1.1), but has been rewritten in Microsoft’s new develop environment Visual Studio 2005 (.NET Framework 2.0).
Before we started to write the program, Thule gave us a specification of requirements that contained information of possible functions in the program. The specification of requirements has been changed a couple of times during our work. We have also put up a website where bugs and changes could be reported.
Except a part in this report, where we describe how the program is built, how we have solved problems, there is also theoretical information about how databases, XML and other techniques work.
The result of this project became an application, which the personnel at Thule can use while they visit their customers. The saved information can later be synchronised with the server.

Full textCyber physical systems, robotics and simulation are areas of major focus as they play a big part in industry 4.0. The aim of the project is to develop the robotic laboratory at the University of Gävle to be more adapted to the introduction of CPS by creating a virtual robotic cell and developing the gripper of the robots. The virtual robotic cell are going to increase the safety in the laboratory and make it possible for more people to work with the robots at the same time. The robots and software used in the project were developed by the company KUKA. Three different software’s were used for the virtual robotic cell in the project. The two most commonly used were simulation and programming. The third software had the possibility to interconnect and control the other two software’s. The virtual robotic cell was developed in the simulation software and also programs were created that the physical robots in the laboratory performed. The physical robots did not move in the same way as the virtual model. Troubleshooting was performed and it showed that the problem was with the physical robots. Therefore KUKA will accomplish maintenance work on the robots. The validation of the virtual robotic cell were for that reason performed in the simulation program. When the physical robotic cell is operating correctly it will also be able to validate that the virtual robotic cell is working. A software that gave the gripper more functionality was installed on the robots. The software that was used was developed by KUKA and were available in the laboratory. The functions make the gripper easier to manage in manual driving and programming. The software that performs the interconnection of simulation and programming software is in need of further analyzation in order for the virtual robotic cell to be able to execute more functions. The virtual robotic cell is available for everyone at the university and can be used to understand how the robots work. Programs can be optimized in the virtual environment and performed by the physical robots.

A problemon the Internet is knowing who and what you can trust. One way to get around this trust issue isto use social media. Meanwhile, social media have consistently increased in popularity in recentyears. The purpose of this paper is to examine how recommendation systems and SNS canbenefit from each other while the practical problem of getting recommendations from one’s(online) friends are solved. This is achieved by using the research strategy design science anddeveloping an IT artifact. The IT artifact is a prototype of a new online service. Based on asurvey of the prototype and the main concept, conclusions are drawn about how a generalpersonal recommendation system can be created. The research shows that it is possible tocreate such a system and that there is a need for a general personal recommendation systembased on the information stored in social media.

Full textDenna rapport beskriver arbetet med att automatisera testningen av noder hos CCS på Ericsson. Målet var att var tredje timma konfigurera noderna med binärfiler kompilerade från den senaste källkoden och sedan testa dem. Detta ska ske helt automatisk utan att användarens hjälp och konfigurationen ska använda det befintliga konfigurations verktyget CICC. Innan arbetet påbörjades skulle felrapporter analyseras för att se om det fanns något att tjäna på automaseringen.Uppgiften löstes genom att först titta på felrapporterna och konstatera att det fanns rum för förbättringar, främst gällande omstarter. Efter det automatiserades CICC som tidigare körts via en GUI. För att schemalägga konfiguration och testning användes testverktyget Jenkins. Jenkins använder sig av ett s.k. wrapperskript som kör CICC och testfallen. Wrapperskriptet sköter även felhanteringen och skriver sedan resultatet av körningen till en XML fil som läses av Jenkins.Resultaten av testen går sedan att se i Jenkins via ett webinterface. Där går det att se resultatet av wrapperskript körningen och testerna, om det blev några fel finns det felmeddelanden med anledningen till felet. Misslyckade tester visas också.Projektet visar att med automatisk testning som sker oftare kan fler fel hittas tidigare och därför åtgärdas snabbare. Innan arbetet används skarpt bör förbättringar ske som tillexempel att köra konfiguration och testning av olika noder parallellt med varandra i wrapperskriptet, för att klara tidsbegränsningen när det är flera noder.

Full textThe swedish healthcare system is facing some challenges related to the electronic medical records that are being used. The healthcare personnel are experiencing some difficulties with the systems, which affects their daily work in a negative aspect. Studies have shown that the personnel actively must use different systems in parallel to get a complete understanding of a patient's status. Furthermore, this makes the care system as a whole more complicated and inadequate.The communication between developers and healthcare can be seen as a complex process since they do not have an complete understanding of each others ways of working. Also, units for bringing together user needs in a structured manner does not exist. This study aims to examine if, and if so, how the needs of healthcare personnel are being involved in the development process of electronic medical records and if this has resulted in a more user adaptive system. The study will focus on the electronic medical record named TakeCare, which is the most used electronic medical record system inside Region Stockholm. This report partly consists of a literature study that aims to establish a theoretical background focusing on user-centered processes of product development, methods for analysing user needs, how user involvement can be conducted and what kind of difficulties that can be identified. The report also consists of an empirical study with focus on semi structured interviews with six different respondents. These respondents are both healthcare personnel, a product owner for a development team, a chief from a company that specializes in managing the electronic medical record TakeCare and a chief specialized in administrative healthcare. Furthermore, an analysis, a comparison and a discussion were followed out concerning the information gained from the theory and empirical study. The results from the study shows that user involvement during the product development process of TakeCare exists, but not to an enough extent that fulfills the user needs. This is not caused by unwillingness to adapt user involvement in the process, but a lack of structure and inadequate communication between developers and users. One particular user need that repeatedly has been expressed by the healthcare personnel, but not been fulfilled, is the lack of software compatibility between the electronic medical record and other electronic systems within the healthcare sector. The lack of software compatibility have resulted in that the users having to perform the same task repetitively, which has an impact on patient safety but also results in reduced time spent on the patients.

Full textComputer vision is a rapidly growing, interdisciplinary field whose applications are taking an increasingly prominent role in today's society. With an increased interest in computer vision there is also an increasing need to be able to control cameras connected to computer vision systems. At the division of computer vision, at Linköping University, the framework EDSDK++ has been developed to remotely control digital cameras made by Canon Inc. The framework is very comprehensive and contains a large amount of features and configuration options. The system is therefore largely still relatively untested. This thesis aims to develop a demonstrator to EDSDK++ in the form of a simple active vision system, which utilizes real-time face detection in order to control a camera tilt, and a camera mounted on the tilt, to follow, zoom in and focus on a face or a group of faces. A requirement was that the OpenCV library would be used for face detection and EDSDK++ would be used to control the camera. Moreover, an API to control the camera tilt was to be developed. During development, different methods for face detection were investigated. In order to improve performance, multiple, parallel face detectors using multithreading, were used to scan an image from different angles. Both experimental and theoretical approaches were made to determine the parameters needed to control the camera and camera tilt. The project resulted in a fully functional demonstrator, which fulfilled all requirements.

Full textBusiness systems lacking a clear interface and subsequently a diminished usability, can lead to limited usage or no usage of parts of the system. It may therefore be critical to have a process outlined for the development of such system and its interface to ensure that all parts of the system are used. The objective of this case study was to investigate whether it is possible to develop a process description for IT projects at the initial stages of the development phase of a new interface in a system. More specifically, the question investigated in this report follows: “How should a development method or development process for IT systems look to seize scientific, theoretical and technical aspects of Human Computer Interaction (HCI)?” A case study of the project was carried out at the company GMP-Systems AB. A literature-study on aspects of Human-Computer Interaction (HCI) was carried out to arrive at a result and answer the question. Further, an analysis was conducted to consider whether the technical implementation of such process can be accomplished by adopting frameworks. In addition, interviews were conducted with users that have interacted with the system, and an analysis was carried out on the feedback provided to develop prototypes for the system. A development method and process description linked to the literature and the experience gained from the projects case study is outlined in the result section. To the client, GMP-Systems, a prototype, a use-case model[1] with user-stories[2] and a sequential diagram[3] will be delivered. Keywords: HCI, evaluation method, Angular JS, Knockout JS, React, Moqups, process description, development method. [1] Use-Case model is a description of actions that a user can perform and defines the interaction between the roles of a system to accomplish a goal[2] User stories are a tool in system development to provide a description of the desired functionality, often from an end user perspective.[3] A sequential diagram shows how objects operate with one another and in what order.

Full textThe goal with this thesis project has been to collect information for a technical consulting company in order to increase their knowledge about autonomous systems and vehicular communication. The status of how various operators work with active safety systems and how the systems are implemented in current and future vehicles has been investigated through extensive literature studies, interviews and market research. The autonomous systems can collect information from the surrounding through sensors and contribute to better traffic efficiency, increased safety, lighter cars and a better environment. Through vehicle communication, the vehicle can communicate with each other in order to guarantee a safe ride. In 2030 the inner city constitutes of autonomous, electrified public transport to transport people on demand, meanwhile private cars are prohibited. Potential needs for the human in a fully, autonomous car has been identified and various product development methods has been applied in order to develop two conceptual solutions for a future car interior. The solutions show the interaction between human and system since entertainment and comfort becomes important in a fully, autonomous car. Each solution is state-owned and holds four passengers. In the solutions, the seats are placed in regard to facilitate communication between the passengers. The passengers can be entertained or informed individually or collectively by text, sound and images.

Full textMost of the research on sustainability and Management Control Systems is based on large businesses even though the majority of all companies in the European Union are small and medium sized businesses. Small businesses can make a big impact on the current climate crisis, but since sustainability can be a complex issue and more advanced management in small business is limited, working towards sustainable development in small business could be a challenge. Therefore, the purpose of this thesis is to study how small businesses work to be more sustainable using Management Control Systems. For data collection, interviews were conducted in four small businesses who work with sustainability. The study finds that it can be hard for small businesses to work with sustainability due to lack of resources, which makes the use of Management Control Systems more informal and value based.

Full textStocktaking is an exhausting process where employee’s collects data and is something that most companies do, although what they are collecting differs from business to business. Because it is a resource-waste to solve same problem multiple times, without reusing previous solutions, the student have choosen to study an overall solution for a stocktaking system that can be used by multiple businesses.The purpose of this report is to establish the end-user requirements on a stocktaking system and study which technical solutions can be used when developing a stocktaking system.The study used an abductive method with a case study on stocktaking. For the case study the empiricism was collected with interviews. A meta-analysis was implemented for the purpose to seek and analyse relevant literature.The result of the study was a requirement specification for an inventory system based on the forest and stock industry. The result also contains technical solutions that can be applied on the system in order to fulfill the requirements. In parallel with the study an attempt was made to develop a prototype of a stocktaking client togheter with Sweco that met both their requirements and requirements that was obtained from the interviews. The results show that the stocktaking client can manage to create, save and recreate dynamic forms. When forms are created their controls also have the ability to specify restrictions. The client can interpret these restrictions and validate the inputs before saving results. The results of the study also implies that a feasibility study of a system tend to find hidden requirements.The primary limitations of the study were time. If the study had a larger timescope more time could have been spent on collecting empirical data and gather end-user requirements.
