Brienza, Giampietro. "Analisi di risposta sismica locale e protezione sismica degli edifici: applicazione di FVD nella progettazione dell'ampliamento del Maria Cecilia Hospital di Cotignola (RA)." Master's thesis, Alma Mater Studiorum - Università di Bologna, 2020. http://amslaurea.unibo.it/21054/.
Full textAbstract:
E’ stato indagato il comportamento degli edifici equipaggiati con un sistema di protezione sismica passivo basato sull’utilizzo di dissipatori fluido viscosi non lineari.
L’elaborato vede una prima parte nella quale si individuano i metodi per lo svolgimento dell’analisi di risposta sismica locale.
La seconda parte si concentra sui metodi di protezione sismica degli edifici e in particolare sul controllo dello smorzamento con dissipatori fluido viscosi. Ne è stato studiato il comportamento meccanico e sono stati analizzati i criteri di progettazione ed integrazione all’interno del sistema strutturale.
L’ultima parte della presente tesi, svolta in collaborazione con lo Studio Tassinari e Associati di Ravenna, raccoglie le elaborazioni ed i risultati ottenuti dall’applicazione degli aspetti presentati nelle precedenti parti alla progettazione dell’ampliamento previsto per il complesso ospedaliero di Maria Cecilia Hospital di Cotignola (RA) del Gruppo Villa Maria. E’ stato sviluppato il confronto in termini di danni attesi a seguito di sisma e di costo di realizzazione tra diverse strategie progettuali: con dissipatori, a comportamento dissipativo e a comportamento non dissipativo. I risultati ottenuti con i metodi di predimensionamento sono stati verificati attraverso analisi dinamiche non lineari con impiego di storie temporali, come previsto dalla normativa vigente.
I risultati hanno fornito una soluzione strutturale con dissipazione aggiuntiva vantaggiosa dal punto di vista della sicurezza degli elementi strutturali e non strutturali, che comporta un investimento poco superiore alla soluzione tradizionale. Il vantaggio rilevante è che a seguito di sisma non sono previsti danni e plasticizzazioni agli elementi strutturali inoltre la riduzione delle accelerazioni e degli spostamenti ai quali si sottopone la costruzione permette di salvaguardare gli elementi non strutturali e, aspetto fondamentale nell’ambito di strutture sanitarie e di ricerca, i contenuti.

Métodos de migração baseados na equação da onda unidirecional apresentam limitações no imageamento de refletores com forte mergulho e no tratamento de ondas evanescentes. Utilizando a expansão de Padé complexa na solução da equação da onda unidirecional para imageamento em geofísica é possível tratar ondas evanescentes, estabilizando a migração e dispensando um tratamento especial para absorção nas fronteiras do domínio. Utilizando várias parcelas na expansão de Padé, refletores com forte mergulho podem ser corretamente migrados. Nesta dissertação aplicamos a equação da onda unidirecional com expansão de Padé complexa para implementar dois algoritmos de migração em profundidade pré e pós empilhamento: a migração por diferenças finitas (FD) e a migração por diferenças finitas e Fourier (FFD). O estudo das curvas de dispersão e da resposta impulsiva dos operadores de migração nos permitiu escolher o número adequado de parcelas na expansão de Padé e os coeficientes da expansão que garantem estabilidade à continuação do campo de onda para um ângulo de mergulho máximo prescrito. As implementações foram validadas nos dados Marmousi e no modelo de domo de sal da SEG/EAGE mostrando que refletores com forte mergulho foram corretamente migrados, mesmo na presença de forte variação lateral de velocidade. Esses resultados são comparados com outros métodos de migração baseados na equação da onda unidirecional ressaltando a qualidade da aproximação estudada neste trabalho.
Seismic Migration by downward continuation using the unidirectional wave equation approximations has two shortcomings: imaging steep dip reflectors and handling evanescent waves. Complex Padé approximations allow a better treatment of evanescent modes stabilizing the finite difference migration, and does not require special treatment for domain boundaries. Imaging of steep dip reflectors can be improved using several terms in the Padé expansion. This dissertation discuss the implementation and evaluation of complex Padé approximation for finite difference migration and Fourier finite difference migration. The study of the dispersion relation and impulsive response associated to the migration operator is used to select the number of terms and coefficients in the Padé expansion which assures stability for a prescribed maximum reflector dip. The implementations are validated in the Marmousi and SEG/EAGE salt model datasets, and compared to other wave equation migration methods. The results of FD and FFD complex Padé migrations can handle steeper dips, and present a much lower signal to noise ratio than their real valued counterparts.

Full textAbstract:
The aim of the Thesis is theoretical clarification of the issues of photovoltaic power plants, their diagnostics, inspection and performance measurement, including negative impacts on their operation and subsequent application of theoretical knowledge during practical inspection and diagnostics of PV power plants. In its introductory part, the Thesis deals with design, manufacturing and development of PV cells and panels and describes other necessary elements and components, including their use in individual types of photovoltaic systems. Another part describes electric parameters of PV cells and panels, especially the parameters that can be found out by measurement of V-A characteristics and also the parameters affecting the shape of the V-A characteristics. The third part is focused on failures of photovoltaic systems, which include various defects of photovoltaic cells and panels, it also provides for adverse factors affecting operation of the entire system, associated not only with weather influences but also with the actual design of the photovoltaic system. The fourth part deals with possibilities of increasing the cost-effectiveness of electricity generation by PV power plants on the basis of practical experience of their operators. The subsequent part determines, on the basis of technical standards, procedures for PV power plant inspections, the procedures for measurement and diagnostics of PV power plants and also other prerequisites connected with inspections and measurements. This part includes also a description of requirements for measuring devices, most frequent measurement errors, adverse impacts affecting measurements and methods of assessment of the data measured. The last part of the Thesis is practical. At first it deals with verification of the impact of defects of PV modules on the shape of their V-A characteristics, then with execution of inspections and diagnostics of a particular PV power plant, evaluation of the data identified and measured, as well as with a proposal of optimisation measures to increase cost-efficiency of the operation of that particular PV power plant.

The diploma thesis deals with the topic of free-form deformations. The main goal of this work were elaboration of theoretical knowledge about this issue and the programming of selected methods od free-form deformations. The first part describes the required spline theory, matrix calculus and free-form deformations. The resulting version shows three programs. The first program compares the selected free-form deformation methods to the example of the 4x4 control point grid. The second program serves as a generalization for the general case of grid of control points. The last program is based on direct manipulation of arbitrary surface point and following recomputation of the control points to obtain demanded shape.

Full textAbstract:
Introduktion: Spirometri är en metod som utförs för att utesluta eller bekräfta en lungsjukdom. Dynamisk spirometri innebär mätning av lungvolymsförändringar över tid och omfattar både långsam och forcerad spirometri. Vid långsam spirometri mäts vitalkapacitet (VK). Vid forcerad spirometri mäts forcerad exspiratorisk volym på en sekund (FEV1), forcerad vitalkapacitet (FVK) och FEV%. Spirometri utförs i sittande position men den kan också utföras i stående position. Syftet med studien var att jämföra och se om det föreligger en signifikant skillnad för VK, FVK, FEV1 och FEV% vid dynamisk spirometri mellan sittande och stående position hos studenter utan känd lungsjukdom. Material och Metod: Studien bestod av 21 frivilliga studenter med åldrarna 21-32 år, där 18 var kvinnor och tre män. Datainsamlingen utfördes vid Örebro universitet och variablerna som mättes vid undersökningen var: VK, FVK, FEV1 och FEV%. Mätningarna upprepades minst tre gånger i både sittande och stående position och de fick inte skilja sig åt mer än 150 ml. Ett parat t- test användes för att se om det förelåg en statistisk signifikant skillnad i mätvärdena mellan sittande och stående position. Resultat: Det parade t-testet visade att det inte föreligger någon statistiskt signifikant skillnad i variablerna VK (p = 0,19), FVK (p = 0,87), FEV1 (p = 0,37) och FEV% (p = 0,26) mellan sittande och stående position. Slutsats: Det föreligger ingen statistiskt signifikant skillnad för dynamisk spirometri mellan sittande och stående position. För att få en uppfattning om hur kroppsposition påverkar spirometri behövs en större population.Introduction: Spirometry is a method performed to rule out or confirm a lung disease. Dynamic spirometry involves measuring lung volume changes over time. The dynamic spirometry includes slow and forced spirometry. With slow spirometry, vital capacity (VC) is measured. In forced spirometry, forced exspiratory volume of one second (FEV1), forced vital capacity (FVC) and FEV% are measured. Spirometry is performed in a sitting position but can also be performed in a standing position. The aim of the study was to compare whether there is a significant difference for VC, FVC, FEV1 and FEV% in dynamic spirometry between sitting and standing position in students without known lung disease. Method and Materials: The study consisted of 21 volunteer students aged 21-32, of whom 18 were women and three men. The data collection was performed at Örebro University and the variables that were taken into account when performing it were: VC, FVC, FEV1 and FEV%. The maneuvers were repeated at least three times in both sitting and standing positions and they did not differ more than 150ml. A paired t-test was performed to see if there is a statistically significant difference in the measured values between sitting and standing position. Result: The paired t-test showed that there is no statistically significant difference in the variables VC (p = 0.19), FVC (p = 0.87), FEV1 (p = 0.37) and FEV% (p = 0, 26) between sitting and standing position. Conclusion: There is no statistically significant difference for dynamic spirometry between sitting and standing position. To get an idea of how body position affects spirometry, a larger population is needed.

Tradisjonelle arbeidsformer i dagens byggebransje vier lite oppmerksomhet til forvaltning, drift og vedlkehold (FDV) av bygninger. BIM, bygningsinformasjonsmodellering, kan bidra til en ny digital arbeidsprosess, hvor FDV står i sentrum. Resultatet av en slik prosess er en modell, en database, hvor all informasjon om et bygg ligger lagret.LYDIA er FDV-programvare, utviklet og levert av Lydia AS. De ønsker å videreutvikle LYDIA i retning BIM, og se på hvordan sammenhengen BIM-LYDIA kan utføres i praksis. Lydia AS opplever i dag størst utfordringer ved import av informasjon til LYDIA-databasen. Kundene samler manuelt inn store mengder informasjon til databasen. Erfaringer viser at endel kunder strever med å forstå bruksnytten av LYDIA.Systemarkitekturen presentert i oppgaven løser Lydia AS sine forutsetninger for overgangen BIM-LYDIA. Funksjonaliteten i LYDIA er opprettholdt. buildingSMART sitt standardiserte filformat, IFC, er brukt som utgangspunkt for overføring av informasjon. Løsningen er realiserbar innen andre kvartal 2014. Modellen forenkler dagens importarbeid. Lydia AS sine kunder slipper manuell dataregistrering som øker risikoen for feil. Ved import direkte fra BIM forenkler man prosessen med å hente informasjon til LYDIA-databasen. Modellen bygger likevel ikke oppunder en ny samarbeidsprosess. Digitale arbeidsformer kan endre de tradisjonelle arbeidsformene i byggebransjen. Utgangspunktet for slike arbeidsprosesser er større tillit og mer fokus på samskaping. Lydia AS må selv tenke gjennom hvilken retning de ønsker å ta for fremtidige LYDIA.

Full textAbstract:
FAD * for Stadsgårdskajen Re-introduction of some of the knowledge from the master builder to the contemporary architect. This project investigates the interaction between designing architecture and building architecture in a computer controlled context. Algorithms have been developed to simulate and control an automated in situ brick stacking process. Brick laying is a well researched topic for robotic processes. It is an ideal material for building with robots (in Stockholm) since it is a generic building block that is cheap and easy to produce locally. Corbeled vaults, instead of keystone vaults, can be built without support and with all identical elements and are therefore also suitable for robotic fabrication. The algorithms have been incorporated in a parametric model that have been used to develop public building at Stadsgårdskajen, Stockholm. FAD is about creating and explore a different architectural expression as well as reintroducing the brick as a relevant construction material for Stockholm.FAD* för Stadsgårdskajen Återinförande av några av byggmästarens förmågor till den samtida arkitekten I detta examensarbete undersöks förhållandet mellan att designa arkitektur och att bygga arkitektur i en datorkontrollerad miljö. Algoritmer har utarbetats för att simulera och styra en automatiserad in situ murningsprocess. Inom fabrikation och automatisering med industrirobotar är tegelband ett välundersökt ämne. Tegel är ett idealiskt material vid byggande med robotar. Det är enkelt och billigt att framställa och tegel som byggkloss är en lämplig typologi för addativ fabrikation med robotar. Valv byggda genom utkragning istället för traditionella valvbågar kan byggas utan stöd och med identiska element. Därför är denna byggnadsteknik även lämplig för additiv fabrikation med robotoar. Algoritmerna har intergrerats i en parametrisk modell som har använts för att formge en offentlig byggnad på Stadsgårdskajen i Stockholm. FAD handlar såväl om skapande och utforskande av ett nytt arkitekturspråk som av återinförande av tegel som ett betydelsefullt konstruktionsmaterial i Stockholm.

Full textAbstract:
Espécies de microalgas como Chlorella sorokiniana têm sido investigadas para as mais variadas aplicações como biocombustíveis, nutrição e a recuperação de nutrientes. Entretanto, a separação de microalgas do meio líquido permanece um desafio tanto técnico quanto econômico. O objetivo deste trabalho é propor e investigar a utilização de pré-ozonização e flotação por ar dissolvido para a separação sólido-líquido de Chlorella sorokiniana cultivada em meio padrão M8a em fotobiorreator flat panel, utilizando polímero catiônico à base de poliacrilamida como coagulante. Primeiramente, foi avaliado o sistema de tratamento com flotação por ar dissolvido, que foi otimizada em escala de laboratório visando eficiência de remoção de algas e flexibilização do sistema. Utilizando dosagens de polímero catiônico de 10 mg L-1 obteve-se remoções de cor aparente, turbidez e densidade óptica próximas de 95 % em pH 7. Posteriormente, a etapa de mistura lenta foi retirada do sistema, a razão de recirculação foi diminuída de 10 para 4 % e após essas alterações, obteve-se remoção de microalgas acima de 90 % para dosagem de polímero de 10 mg L-1. Para analisar o efeito da pré-ozonização a dosagem de polímero catiônico foi reduzida para 7 mg L-1, e observou-se que com FAD esta dosagem removeu 81,12 % de turbidez, e após pré-ozonização por 5 minutos seguida de FAD a eficiência de remoção de turbidez chegou a 91,78 % e remoção de cor aparente aumentou 6,25 %. A utilização da pré-ozonização permitiu utilização de velocidades de flotação da ordem de 24 cm min-1 sem prejuízo da eficiência de remoção de cor, turbidez e densidade óptica. Observou-se que a pré-ozonização demonstra efeitos positivos no sistema de tratamento, mas constatou-se uma dosagem ótima de ozônio, e que a partir desta dosagem a eficiência do tratamento pode ser prejudicada. Foi constatado que uma possível explicação para esse fato seja a liberação de matéria orgânica algal após pré-ozonização, em dosagens acima do valor ótimo de dosagem de ozônio.Microalgal species as Chlorella sorokiniana have been investigated for a variety of applications such as biofuels, nutrition and nutrient recovery. However, the solid-liquid separation microalgae of the liquid medium remains a challenge both technical as economical. This work aims to propose and investigate the use of preozonation and dissolved air flotation for solid liquid separation of Chlorella sorokiniana cultivated in standard M8a medium in a flat panel photobioreator, using cationic polyacrylamide based polymer as coagulant. Initially, treatment system including dissolved air flotation was evaluated, which was optimezed at laboratory scale targeting removal efficiency of microalgae and system flexibility. Using cationic polymer dosage of 10 mg L-1, were obtained apparent color, turbidity and optical density removals nearly to 95% in pH 7. Further, the step of slow mixing was removed from the system, the recycle ratio was decreased from 10 to 4% and after these changes, was obtained microalgae removal over 90% at polymer dosage of 10 mg L-1. To analyse the effect of preozonation, cationic polymer dosage was decreased to 7 mg L-1, and was observed 81.12 % turbidity removal with this polymer dosage at FAD, and after 5 minutes preozonation followed by FAD, turbidity removal efficiency reached 91.8 % and apparent color removal increased 6.25 %. The utilization of preozonation allowed use of flotation velocities in the order of 24 cm min-1 without damaging variables removal efficiency. It was observed tha preozonation shows positive effects in treatment system, but was found an optimum ozone dosage from which the treatment efficiency is hampered. It was observed that a possible explanation to this fact is the release of algogenic organic matter after preozonation in dosages over the optimum value of ozone dosage.

Sagor, Md Hasanuzzaman. "Differentially fed active antennas." Thesis, University of Greenwich, 2014. http://gala.gre.ac.uk/13826/.
Full textAbstract:
The original contribution to knowledge made by this research work is demonstrating the benefits of differentially fed balanced transmit antenna in modern communication system. Extensive experimental studies have established the fact that a true differential amplifier feeding a balanced antenna offers higher linearity and lower distortions compared to the single ended feeding technique, even while using the same amplifier. With continuing advancements in personal communications in this era of digital economy, the demand for wireless connectivity has grown radically, resulting in stringent performance requirement for RF components. Differential circuits are preferred choice in RFIC design due to its good noise immunity and low distortion characteristics. But it is observed that single ended PAs and LNAs are used for the feeding part because of the antenna industry’s tendency to stick to conventional 50Ω interface. Therefore, differentially fed transmit balanced antenna is an area of current research, which has been studied in this thesis. The study was set out with a review of the state-of-the-art in active integrated antennas. Following that, the ground plane influence on antenna radiation pattern was explored and novel techniques to compensate the effects were presented. It was observed that the current flow in a coaxial cable also affects radiation pattern. Hence, a novel method was proposed to measure wireless devices in the anechoic chamber eradicating the need of any cable attachments. Broadband differential amplifiers were then reviewed with a view to feed balanced and unbalanced antennas for demonstrating the potential of differential feeding technique over the conventional one. The amplifier with differential output interface exhibited higher gain and linearity in both bench test and radiated power test. Further improvement in linearity was reported by lowering the output resistance of the amplifier. Afterwards, a broadband antenna with stable radiation pattern and impedance was designed to carry out radiated harmonic measurements, which illustrated that the fully differential output configuration possesses significantly lower harmonic distortion. All these measurement results have suggested that balanced antenna fed by differential amplifier can be the best solution for applications demanding higher output power, greater linearity and lower distortion. Therefore it is recommended to re-evaluate the idea of power amplifier and antenna interface in RF front-end designs.

Full textAbstract:
The hexanucleotide repeat expansion GGGGCCn (also known as G4C2n) localizes in the first intron of the C9ORF72 gene and is the most common genetic cause of ALS and FTD (C9ALS/FTD). The pathomechanisms proposed for C9ALS/FTD suggest that from sense (G4C2)n- and anti-sense (C4G2)n-containing transcripts originate two different mechanisms of toxicity: i) by the alteration of RNA processing due to binding and sequestration of RNA-binding proteins, thereby leading to impairment of RNA metabolism; and ii) by their unconventional Repeat-associated non AUG (RAN) translation into five different dipeptide-repeats (DPRs). In addition, pathological expansion of (G4C2)n reduces the C9orf72 transcription causing loss of function of the C9ORF72 protein. The toxicity of some of these DPRs has been showed in several cell lines, in iPSC-derived neurons, in Drosophila and in mouse models. An impairment of the ubiquitin-proteasome system (UPS) due to aggregation of toxic proteins is largely demonstrated in neurodegenerative disorders and among the mechanisms of DPR-related toxicity. RAN translation of (G4C2)n-RNAs has been recently shown to require a near-cognate start codon upstream of the repeat in frame +1 and to be triggered by stress conditions in a cap-dependent or cap-independent way. However, the mechanism regulating RAN translation is still largely unknown. Importantly, no small molecules are known to selectively modulate RAN translation, even if antisense oligonucleotides (ASOs) and small molecules binding the r(GGGGCC)n have been proposed as therapeutics for C9ALS/FTD. In addition, no effective pharmacological approach to reduce the pathological load of DPRs is currently available.
Here, I developed a high-throughput drug-screening assay to identify small molecules and relative molecular targets that can modulate the DPR level. Among the identified hits, two hits reduced DPRs expression levels triggering the protein clearance system in vitro. Moreover, the screening identified compounds having the same target that increased DPRs expression levels indicating the targeted pathway as a crucial modulator of the translation process of the C9orf72 repeat-containing mRNAs. Conversely, I showed that pharmacological inhibition of the pathway reduced DPRs expression levels in vitro, while in vivo it rescued climbing ability and increased life span of Drosophila flies carrying G4C2X36 repeats. Moreover, genetic ablation of the target reduced DPRs expression levels by decreasing their translation efficiency in vitro and rescued the pathological phenotype in vivo. Together, the results show the identification of new pathways as new drug targets for C9ALS/FTD.

However, the maintenance requirements and potential failure of brushes and slip rings is a significant disadvantage of DFIG. This has led to increased interest in brushless doubly-fed generators. In this thesis a Brushless Doubly-Fed Reluctance Generator (BDFRG) is compared with DFIG from a control performance point of view. To compare the performance of the two generators a flexible 7.5kW test facility has been constructed. Initially, a classical cascade vector controller is applied to both generators. This controller is based on the stator voltage field orientation method with an inner rotor (secondary stator) current control loop and an outer active and reactive power control loop. The dynamic and steady state performance of two generators are examined experimentally. The results confirm that the BDFRG has a slower dynamic response when compared to the DFIG due to the larger and variable inductance. Finally a sensorless Direct Power Control (DPC) scheme is applied to both the DFIG and BDFRG. The performance of this scheme is demonstrated with both simulation and experimental results.

Le diagnostic du parc routier est une étape indispensable préalable à l'entretien et la réparation des structures de chaussées. L'importance d'une plus grande finesse de l'analyse des résultats issus des méthodes de contrôle non destructif peut permettre de réaliser, à terme, des économies sur les coûts et énergie mis en jeu lors de la maintenance et la construction. Ces travaux de doctorat présentent un modèle thermo-visco-elastique permettant d'intégrer le comportement des matériaux bitumineux composant une chaussée par l'utilisation du module et de l'amortissement complexe issu des courbes maitresses. La résolution du problème dynamique est réalisée à l'aide d'une approche fréquentielle. Cette approche est appliquée en particulier à un essai FWD sur lequel des variations climatiques sont étudiées. Des essais in situ, réalisés sur deux sites instrumentés, permettent de valider le modèle. Les bons résultats obtenus suggèrent l'utilisation de ce modèle à travers une analyse multicritère sur les bassins de déflexion et les historiques pour le développement futur d'un modèle de retro calcul dynamiqueThe diagnosis of the road fleet becomes a necessary step prior to themaintenance and the repair of pavement structures. The importance of a finer analysis of the results of the non-destructive testing methods can eventually achieve to cost and energy savings for the maintenance and construction. This phD thesis introduces a thermo-visco-elastic model for intersting the behavior ofbituminous pavement materials, using the complex modulus and damping from master curves. The resolution of the dynamic problem is performed thanks to a frequency approach. This approach is particularly applicable to a FWD test on which climatic variations are studied. In situ tests, carried out on two instrumented sites, are used to validate the model. The obtained of good results suggests the use of this model through a multi-criteria analysison deflection basins and of the records for the future development of a backcalculation dynamic model

The objective of this analysis is to develop econometric models for forecasting fed cattle basis as well as compare these models with historic averaging methods of forecasting basis popular in existing literature. The econometric analysis also aims to identify important determinants of fed cattle basis. Both monthly and weekly models were assessed with data provided by the Livestock Marketing Information Center. All models analyzed the three regions of Nebraska, Kansas, and Texas. Monthly historic average approaches utilized historic fed cattle futures and fed cattle cash price series from January of 1995 through December of 2010. Weekly historic average approaches utilized historic fed cattle futures and fed cattle cash prices series from June of 2001 through December 2010. Data collected post mandatory price reporting implementation in 2001 was used in all econometric models. Overall lags of fed cattle basis, the spread between the nearby live cattle futures contract and the next deferred futures contract, and seasonality regularly proved to explain much of the variation in fed cattle basis in the econometric modeling. Multiple historic average based models were examined on both monthly and weekly frequencies. Once all competing models were estimated in-sample, out-of sample testing was conducted. The forecasting errors of all weekly models were compared to determine which methods prove to be dominant forecasters of fed cattle basis. This testing suggests historic averaging methods outperform the alternate econometric models in out-of-sample work. The econometric models helped to reveal some of the important factors determining fed cattle basis, however lags in collecting data on these factors may inhibit the forecaster’s ability to use these techniques in real time. One interesting revelation in regards to historic averages is the potential of Olympic averages as forecasters. These methods have not been explored in previous academic literature but tend to perform quite well in comparison with other methods explored.

Full textAbstract:
Flavor lexicons are used in sensory evaluation to determine the flavor profile of a food product. The objective of this study was to develop a flavor lexicon for cooked beef, which can then be used in various projects relating to beef quality such as studies investigating animal diet, marinating, ageing, or other enhancements. A descriptive panel of 10 people was used to develop a flavor lexicon of 18 attributes, including astringent, barny, bloody, brothy, browned, gamey, grassy, juicy, fatty, livery, metallic, oxidized, roast beef, and the five basic tastes (bitter, salty, sour, sweet, and umami). In contrast to other studies on beef, this lexicon was developed to include both positive and negative attributes. The lexicon was able to show that rib eye steaks from the Longissimus dorsi muscle in grass-fed animals were significantly (p<0.05) higher in barny, bitter, gamey, and grassy flavors, and lower in juicy and umami flavors. The steaks were also rated by consumers, who showed a preference for grain-fed beef over grass-fed beef. The ratings of the descriptive panel were related to the consumer panel scores to equate the lexicon terms with a positive or negative consumer degree of liking score. Those terms that were considered positive in this study due to their positive correlation with consumer liking include brothy, umami, roast beef, juicy, browned, fatty, and salty. The terms that were inversely associated with consumer liking were barny, bitter, gamey and grassy, among others. A separate descriptive panel was conducted on the Spinalis dorsi (or “cap” muscle) of the rib eye steak, with similar results. Additionally, descriptive and consumer evaluations found no difference between two types of grass diets, namely alfalfa and sainfoin. Different mixtures of beef and chicken were also evaluated to determine flavor differences between the two meats. Chicken was found to be more closely correlated to brothy, juicy, sweet, and umami, among others, while beef was found to be more closely correlated to terms such as gamey, bloody, oxidized, metallic, roast beef, and astringent. Throughout these tests, the newly developed lexicon was shown to be an effective tool for profiling fresh meat samples.

Groundwater-fed rivers form stunning geometries over a range of scales. These rivers grow as water from an underground aquifer reemerges and erodes the overlying topography. Both the aquifer and the overlying topography generate flows along diffusive gradients. We study three features produced by these gradients over different scales: the shape of the valley that forms around a single stream, the network-averaged planform stream shape, and the shape of the drainage basin. First, we identify a new feature in stream valleys - a spatially variable diffusivity - that gives rise to a theoretical valley shape that agrees with the shapes of real valleys. Next, we present evidence and theory for a 120° opening stream confluence angle as a result of lateral rearrangement of streams in response to the pressure field generated by the aquifer. We then study how this mechanism exerts itself on the scale of the network. Finally, we widen our scope and analyze river planform morphology on a continental scale. We identify how branching angles can predict a river basin aspect ratio. We find a relationship between this aspect ratio and river basin scaling exponents with local climate.

The cattle market has drastically changed over the last half century. Today, ranchers and farmers are faced with various governmental regulations as well as fluctuating grain and fuel prices. While beef may still be a commodity, it can be sold in specialized markets, in markets that have enhanced consumer demand. It is nearly impossible for a producer with a small herd to compete with a larger ranch if they are selling their cattle as a commodity. The primary economic objective of the producer is to generate revenue. Producers must be profitable to remain in business as well as provide a livelihood for their family. Providing a quality product is part of the business model. Choice within a marketplace is beneficial for producers and consumers. That said forage-fed beef will prosper in marketplaces where consumers desire their product more than alternate products. If producers are intent on progressively growing their market share, Georgia-grown, forage-fed beef must be marketed correctly. This includes promoting it on a basis of locally grown, pasture raised, and other attributes consumer’s desire. The results of the marketing survey present data that may be helpful when marketing Georgia-grown, forage-fed beef. The weekly consumption of beef products provided insight into the potential scope of the market. Approximately 39 percent of respondents consumed beef products three or more times per week. Additionally, 43 percent of the respondents were not familiar with forage-fed beef. This is a significant share of the market that is possibly open to a new product like Georgia-grown, forage-fed beef. Similarly, traceability of the product was an important feature that customers preferred. In addition to a larger selection of naturally produced beef products, respondents also indicated they were willing to pay more for the product. Approximately 49 percent of the respondents indicated that they would be willing to pay up to a dollar more per pound for Georgia-grown, forage-fed beef. Another 30 percent of the respondents indicated that they would be willing to pay more than $1 per pound for Georgia-grown, forage-fed beef. The results of the survey appear to offer opportunities for producers of Georgia-grown, forage-fed beef to expand their market share.

Resumo: Neste trabalho, desenvolve-se um controlador auto-ajustável com estrutura PID, cuja lei de controle é obtida através da restrição da estrutura do controlador auto-ajustável de variância mínima generalizada, que minimiza as oscilações da variável de saída do processo em torno do sinal de referência e também pondera o esforço de controle exigido. A lei de controle resultante apresenta ainda um parâmetro de ajuste, semelhante ao ganho proporcional, que deve ser fornecido pelo usuário. Para tornar este controlador independente da intervenção do usuário, propõe-se um procedimento baseado em reconhecimento de padrão para o ajuste automático deste parâmetro. Os parârnetros da lei de controle são determinados diretamente através de um algoritmo recursivo de estimação de parâmetros, numericamente robusto. Propõe-se também a introdução de um nível de supervisão para gerenciar o desempenho tanto do estimador de parâmetros quanto da lei de controle

Full textAbstract:
One of the biggest challenges in modern day wireless communication systems is to attain agility and provide more degrees of freedom in parameters such as frequency, radiation pattern and polarization. Existing phased array antenna technology has limitations in frequency bandwidth and scan angle. So it is important to design frequency reconfigurable antenna arrays which can provide two different frequency bandwidths with a broadside radiation pattern having a lower sidelobe and reduced frequency scanning. The reconfigurable antenna array inspired by the properties of metamaterials presented here provides a solution to attain frequency agility in a wireless communication system. The adaptive change in operating frequency is attained by using RF p-i-n diodes on the antenna array. The artificially made materials having properties of negative permeability and negative permittivity have antiparallel group and phase velocities, and, in consequence of that, they support backward wave propagation. The key idea of this work is to demonstrate that the properties of metamaterial non-radiating phase shifting transmission lines can be utilized to design a series-fed antenna array to operate at two different frequency bands with a broadside radiation pattern in both configurations. In this research, first, a design of a series-fed microstrip array with composite right/left-handed transmission lines (CRLH-TLs) is proposed. To ensure that each element in the array is driven with the same voltage phase, dual-band CRLH-TLs are adopted instead of meander-line microstrip lines to provide a compact interconnect with a zero phase-constant at the frequency of operation. Next, the work is extended to design a reconfigurable series-fed antenna array with reconfigurable metamaterial interconnects, and the expressions for array factor are derived for both switching bands.

Full textAbstract:
This research project aims at evaluating a conversion system based on the emerging Brushless Doubly Fed Reluctance Machine (BDFRM) through a comparative experimental study with a traditional and well established slip-ring counterpart, the Doubly Fed Induction Machine (DFIM). One of the main objectives is to establish whether this alternative machine is worthy of industrial consideration in variable speed applications with limited speed ranges (e.g. wind turbines, pump-like drives etc.) in terms of control, reliability, efficiency and power factor performance as major criteria. Such kind of work has not been reported in the open-literature to date and represents the main contribution of the project being undertaken. A conventional and widely used parameter-independent vector control (VC) scheme has been selected for the operation of both the machines using a shaft-position sensor. The VC algorithm has been simulated and implemented in real-time on state-of-the-art eZdsp development platform based on the TMS320F28335 Digital Signal Controller (DSC). The control code has been derived from a programme written in C++ using the corresponding compiler, the Code Composer Studio (CCS). Comprehensive computer simulations have been done in Matlab/Simulink using the parameters obtained by off-line testing of the DFIM and BDFRM prototypes, which have been built in the same stator frame for comparison purposes. The simulation results have been experimentally verified on two identical test rigs where a commercial 4-quadrant cage induction machine V/f drive has been used as a prime mover or load for either the DFIM or the BDFRM subject to their operating mode. The preliminary experimental results on two small-scale prototypes have shown that the BDFRM can achieve competitive performance to the similarly rated DFIM and as such should warrant further investigation and increasing interests of both academic and industrial communities as a potential large-scale wind generator or a pump drive.

Full textAbstract:
Host restriction factors such as Fv1 in mice and Trim5α in primates block retroviral infection through their interaction with capsids. One major form of Fv1, encoded by the Fv1b allele, restricts only N-tropic MLV (N-MLV) when expressed at the lower endogenous level, but also restricts B-tropic MLV (B-MLV) and NB-tropic MLV (NB-MLV) at the higher levels seen in cells transduced with Fv1 b-expressing retroviral vector. However, a previous pull- down study detected almost equal binding of Fv1b to all three MLV capsids. In this study, the relationships between Fv1 binding, restriction and expression level were studied in detail. To study the restriction specificity of Fv1 b at different expression levels, new Tet-On vectors were developed to allow doxycycline-inducible expression of Fv1. These vectors allowed restriction studies from a very low Fv1 b level where no restriction could be observed, to a high level where inhibitions of B-MLV and NB-MLV are also observed. Similar phenomenon is also observed in other Fv1 mutants. By contrast, Fv1 n, even when over-expressed, restricted only B-MLV but not NB-MLV or N-MLV. The binding of Fv1b to different capsids at different Fv1 concentration were compared using a new pull-down assay performed on microtitre plates. Fv1b appears to bind to all MLV capsids at the lowest concentration of Fv1 where binding could be detected. The study was extended to include other Fv1 mutants, and as expected binding could be detected for all restrictive Fv1-MLV pairs. Interestingly, a few outliers including Fv1b vs B-MLV demonstrated strong binding but either weak or low restriction, suggesting there may be other factors causing the lack of restriction. Together, these data suggest that although Fv1b have very similar apparent binding affinities to different MLV capsids, different amount of Fv1b are required for the restriction of N-, B- and NB-MLV.

This research investigated two groups of patients diagnosed with dementia before the age of sixty-five. The patients were diagnosed with Alzheimer's Disease (AD, n = 25) and Frontotemporal Dementia (FTD, n = 37). Patients were assessed for approximately 3 years. The study found that FTD is a valid and useful diagnostic category, and can be reliably differentiated from AD. A combination of behavioural, neurological, and neuropsychological assessments were found to be complementary in the early and accurate diagnosis of early-onset dementia, and the differential diagnosis of FTD from AD. FTD patients were found to have relatively preserved visuo-spatial abilities compared to the AD patients. Problems associated with administering neuropsychological tests to early-onset dementia patients were highlighted. FTD patients were found to deteriorate more rapidly than AD patients, and to have significantly increased behavioural disturbances throughout the course of the illness in comparison with the AD patients. Practical guidelines to assist with care and management of early-onset dementia patients were presented. A strengths-based model of care was outlined. Individualised assessments and care plans were recommended for the development and provision of humane services to early-onset dementia patients. Issues surrounding providing palliative care were discussed.

Full textAbstract:
Syftet med studien var att undersöka hur förstagångsföräldrar samt flergångsföräldrar upplever föräldragrupperna i Dellenbygden (FID). Resultatet från de 19 intervjuerna visade att samtliga föräldrar var nöjda över att träffarna, anordnades. Alla respondenter beskrev att de hade fått information om FID men många upplevde den som otydlig. Förstagångsföräldrarna beskrev att de inte riktigt förstått innebörden av informationen som rörde FID, medan flergångsföräldrarna beskrev den som mer klar och tydlig. Förstagångsföräldrarna hade inga förväntningar av föräldragrupperna medan övervägande flergångsföräldrar hade vissa förväntningar. De flesta förstagångsföräldrar upplevde innehållet som lite tunt medan flergångsföräldrarna upplevde det som bra och givande. Samtliga föräldrar hade kommentarer när det gällde upplägget, där tiden var det som mest kritiserades. Samtliga föräldrar angav att den sociala gemenskapen som träffarna gav var det primära men några tillade att det även var bra saker som togs upp på träffarna. Samtliga föräldrar hade också kritik när det gällde övergången till förskolan som inte fungerat. Ett antal önskningar om förbättringar framkom hos både förstagångsföräldrar och flergångsföräldrar där tiden för träffarna och övergången till förskolan var det primära.
Slutsats: Det är viktigt med tydlig information om innehållet och betydelsen av FID till nyblivna föräldrar. Det är även viktigt för föräldrarna att ges möjlighet att påverka tider för gruppernas sammankomster samt innehållet i dessa grupper. Övergången till förskolan bör enligt föräldrarna ses över då de ansåg det viktigt med fortsatta framtida träffar i grupperna.
The aim of the study was to examine how first-time parents and experienced parents experience the parent groups in Dellenbygden (FID). The results from the 19 interviews showed that all parents were pleased that the meetings had been organized. All respondents stated that they had been informed about the FID, however the majority found that this information had been too vague. The first-time parents described that they had not really understood the meaning or importance of the information concerning the FID, while experienced parents described it as being more clear and evident. The first-time parents had no expectations of parent support, while the majority of experienced parents did have certain expectations. Most first-time parents considered the content a little thin, while experienced parents found it to be good and beneficial. All parents had comments concerning the set-up, with the time of the meetings being the most criticized point. All parents stated that the social community that the group meetings provided was the main benefit, but some added that good things were also brought up at the meetings. All parents also had criticism concerning the transition to preschool as not functioning. A number of desired improvements were generated from both first-time parents and experienced parents, with the time of the group meetings and the transition to preschool being the main points.
Conclusion: It is important to have clear information about the meaning and the importance of FID to new parents. It is also important for the parents to be given the chance to influence the group meeting times and the content of these meetings. The transition to preschool should, according to the parents, be seen as the most important point to be considered at continued future group meetings.

Full textAbstract:
This dissertation, composed of two parts, studies the brushless doubly-fed induction machine (BDFM)- an electric machine with two stator windings, a modified cage-rotor, and, when run synchronously, the electrical properties of a synchronous machine, i.e. precise speed and power-factor control. The first part of this dissertation is dedicated to the development of a two axis (dq) model to aid in design of the BDMF. It improves on the properties of similar models by allowing for the determination of the individual rotor-bar currents and the components of electromagnetic torque produced by each of the two stator windings. The model has the ability to predict both dynamic and steady-state behaviour, the latter verified by experiment and by comparison to predicted results of a different model of the BDFM. The second part of this dissertation, which is the primary focus of this dissertation, is concerned with the phenomenon of inter-bar rotor currents, those which flow between the rotor bars through the rotor iron. Experiments have shown that these currents, present in virtually all die-cast rotors for all types of induction-based machines, seriously degrade the performance of the BDFM by causing increased rotor losses, reduced efficiency, increased stator input power, and increased stator currents, especially when used as a motor. To understand this phenomenon and predict its effect on machine performance, a coupled-circuit model is developed based on harmonic analysis. It is verified through experiments using a specially fabricated rotor in which the rotor bar to rotor iron contact has been promoted. Investigations are conducted using the model to determine the minimum level of insulation needed to obtain satisfactory performance. Results show that the rotor bars must be insulated to an order of magnitude greater than that achieved in the normal die-casting process.

This kind of techniques are prone to efficiency problems when applied to large programs containing many lines of code. This is especially true for software in industrial practice, such as the ones running on Programmable logic controllers (PLC) that are used in a wide variety of tasks from toys to avionics and rail transport. Function Block Diagram (FBD) is a language used for programming PLCs that has gained lots of attention in industrial practice due to its graphical nature. These FBD programs are often used in real time and safety critical systems, and these systems require extensive testing in order to prove that they pass safety requirements of their respective domains. In order to improve the efficiency of applying automated test generation on FBD programs we propose two FBD program slicing algorithms based on the structure of these diagrams and how they are programmed. These FBD program slicing algorithms are applied on several industrial programs for PLCs in order to evaluate their feasibility and what effect slicing has on test generation. Six FBD programs were selected out of 189 provided by Bombardier Transportation Sweden AB. The six programs were sliced according to these FBD slicing algorithms and then evaluated in terms of efficiency and applicability. Our results suggest that slicing can be used to reduce the needed generation time and memory usage required for automated test generation. However, our observations show that slicing can also increase the number of test cases generated and how this test cases are merged into one test suite for the entire program.

Full textAbstract:
Expansion of groundwater-fed irrigation has enhanced agricultural productivity, while simultaneously causing large reductions in groundwater storage. Hydro-economic modelling provides a valuable tool for evaluating trade-offs between agriculture and aquifer sustainability. However, a central argument in this thesis is that the reliability of integrated analysis of groundwater systems may be affected by the failure to consider adequately the variables influencing field-level irrigation decisions and the dynamic aquifer responses to those choices. This thesis addresses this limitation of existing research through three main contributions to the literature. In Chapter 2, a new model of farmers' individual field-level groundwater-fed irrigation decision making is developed. Innovations include the explicit consideration of the role of soil moisture in intraseasonal irrigation scheduling, and evaluation of the impacts of weather variability and well yield on crop production. Application to a case study in the High Plains region of the United States demonstrates that low well yields limit significantly irrigated area and demand for groundwater. Furthermore, it is shown that this important behavioural response can not be captured by existing models that do not consider instantaneous supply constraints imposed by well yield. In Chapter 3, a combination of empirical analysis of observation data, and numerical simulations using the model developed in Chapter 2, are conducted to generate insights about the feedbacks between groundwater and agriculture. Reductions in well yield are shown to have large negative impacts on the productivity of irrigation whereas, contrary to previous assumptions, the response of irrigation behaviour to increased groundwater pumping lifts is found to be minimal. Importantly, this result highlights the need for integrated models to consider a broader range of factors influencing the sustainability of agricultural groundwater use. In Chapter 4, a novel hydro-economic modelling framework is presented that integrates the model of farmers' individual irrigation decision making with a distributed multi-scale groundwater flow model. The model extends the scope of existing research by using pump head-capacity curves to quantify the effect of changing aquifer storage on well yields. Advantages of the modelling framework for policy analysis in coupled agricultural groundwater systems are demonstrated. Specifically, it is shown that the long-term sustainability of irrigated agriculture is influenced by intraseasonal and interannual changes in well yield that depend on famers' pump choice and expectations about future dynamic aquifer responses. Moreover, the model demonstrates that managing the rate of well yield decline may have positive long-term impacts on both agricultural production and farmer welfare that have not been recognised in previous research.
