Incorporated instrumentation includes pressure transducers attached to a pitot-static tube, wall static pressure taps, and a pressure rake; a hotwire anemometry system, and a linear traverse system. These were integrated with a data acquisition (DAQ) processor with analog to digital conversion and digital I/O boards, and controlled using in-house developed LabVIEW software. Testing showed a maximum axial velocity of 38 m/s, which is 84% of the tunnel?s rated speed. The 2-D flow uniformity was within ±7% by pressure rake, and ±3% with a turbulence intensity ?0.11% at full speed using a CTA, affirming the tunnel?s viability as a demonstration platform. Spectral density plots in the boundary layer exhibit typical behavior of fully developed equilibrium turbulent flow with an intertial sub-range present. Future testing of a flat-plate wake for drag modification is planned.

Full textLe ralentissement du mouvement chez les personnes atteintes de fibromyalgie (FM) constitue un fardeau qui s'ajoute aux symptômes de cette maladie. Il est reconnu que la musique peut influencer la vitesse du mouvement chez les individus en bonne santé ; il est plausible qu'elle puisse aussi être utilisée pour contrecarrer le ralentissement des mouvements chez les individus atteints de FM. Les objectifs de cette étude consistaient à estimer a) si marcher en écoutant de la musique à différents tempi modifie la vitesse de marche chez les personnes atteintes de FM; b) si la musique modifie l'humeur, l'intensité de la douleur, l'émotion liée à la douleur et l'effort perçu par ces individus pendant leur marche. Une étude prospective à protocoles individuels (single subject research design) a été réalisée. Huit femmes atteintes de FM ont marché sous deux conditions musicalement différentes (musique lente ou rapide) et sous une condition contrôle (pas de musique). Les variables d'intérêts mesurées comprenaient la vitesse de marche, l'intensité de la douleur, l'émotion liée à la douleur, l'humeur et l'effort perçu. Les résultats ont montré que quatre sujets ont marché plus rapidement lorsqu'ils écoutaient la musique rapide. Aucun changement n'a été noté dans les mesures cliniques. Ces résultats indiquent que la musique pourrait être utilisée afin d'améliorer la vitesse de marche chez les personnes atteintes de FM.

Full textFörare bör göra bedömningar som relaterar till hastighet, såsom bedömningar av medelhastighet, risk, restid och bränsleåtgång. Dessa bedömningar är nödvändiga för att föraren ska kunna välja en optimal hastighet, men också för att allmänheten, politiker och andra intressenter som är involverade i trafikfrågor ska kunna fatta välgrundade beslut. Denna avhandling består av fyra delstudier där förares bedömningar av restid (Studie I och II), bränsleåtgång (Studie III) och medelhastighet (Studie IV) studeras i relation till faktiska fysikaliska mått. Tidigare enkätstudier har påvisat ett kognitivt bias i tidsvinstbedömningar vid höga och låga hastigheter som påverkar mänskligt beteende. Studie I visade att detta bias också förekommer i en primärt perceptuell motorisk uppgift där förarna i studien kör i en körsimulator. Studie II visade att dessa intuitiva tidsbedömningar kan förbättras genom att köra med en alternativ hastighetsmätare i bilen som indikerar den inverterade hastigheten i minuter per kilometer istället för hastigheten i kilometer per timme. I Studie III undersöktes bedömningar av bränsleåtgång vid hastighetsökningar och hastighetssänkningar, och resultaten visar att bedömningarna systematiskt avviker från faktisk bränsleåtgång. Ett intressant resultat var att lastbilsförare i allmänhet underskattade bränslebesparingen som kan göras till följd av en hastighetssänkning. Studie IV visade att subjektiva bedömningar av medelhastighet som avviker från objektiva medelhastigheter kan predicera vägval, vilket tyder på att systematiska fel i dessa bedömningar är robusta och kan predicera vägval. Sammanfattningsvis visar avhandlingen hur bedömningar av medelhastighet, tidsvinst och bränsleåtgång systematiskt avviker från fysikaliska mått. Resultaten har betydelse för modellering av resebeteende och design av förarstödssystem.

In a network, multiple links are interconnected by means of switches. A switch is a device with multiple input and output links, and its job is to move data from the input links to the output links. In this thesis, we focus on a number of fundamental issues concerning the quality of service provided by electronic and optical switches. We discuss various mechanisms that enable the support of quality of service requirements. In particular, we explore fundamental limitations of current high speed packet switches and develop new techniques and architectures that make possible the provision of certain service guarantees. We then study optical wavelength switches and illustrate how similar ideas can be applied in a manner consistent with the current state of optical switching technology. First, we focus on providing rate guarantees over packet switches. We develop a method called rate quantization which converts the set of desired rates into a certain discrete set such that the quality of service guarantees can be greatly improved with a small resource speedup. Moreover, quantization simplifies rate provisioning for dynamically changing traffic demands since it allows service opportunities for different input output link pairs to be scheduled with minimal dependence. We illustrate an isomorphism between packet switch schedulers and Clos networks to develop such schedulers.
(cont.) Next, we evaluate the amount of resource speedup necessary for single stage switches to support multicast rates. This speedup limits the scalability of a single stage multicast switch a great deal. We present an in depth study of multistage switches and propose a number of architectures, along with associated routing and scheduling algorithms. We illustrate how the presence of multiple paths between input output pairs can be exploited to improve the performance of a switch and simplify the scheduling algorithms. Some of our architectures are capable of providing multicast rate guarantees without a need for a resource speedup. We extend our results on switch schedulers and use them for providing service guarantees over optical wavelength switches. We will take the limitations of the optical crossconnects and unavailability of optical memory technology into account, and modify the procedure we developed for electronic switches to make them suitable for various optical wavelength switches. These results will provide understanding of when to move optical switching closer to the end users for an efficient utilization of resources in networks with both optical and electronic technologies.

Full textFixed speed wind turbines completely dominated the market until the mid-1990s and currently. Although most installed wind turbine are variable speed, many fixed speed wind are still in operation. In this context, this work presents a study concerned to coordinated operation of FACTS (Flexible Alternating Current Transmission Systems) device with fixed speed wind energy conversion system (WECS) equipped with a squirrel cage induction generator. The applied FACTS device is based on the control strategy of the Unified Conditioner Power Quality with inverted topology (i-UPQC), and consists of two static converters connected in back-to-back topology. A model was developed in the software PSCAD/EMTDC, tested under four different scenarios and discussed in order to validate the presented theory. The i-UPQC performance was analyzed for improving voltage quality in the point of common coupling (PCC), reduction of the harmonic currents drained from the wind turbine, and increasing the induction generator capacity to remain connected during a momentary collapse in the grid voltage. The i-UPQC presented good performance due to its capability to warrant the quality in the PCC voltage in spite of the wind variation and that the voltage sags at the PCC do not change the stator voltages. About the generator current, the i-UPQC has kept the stator current free of harmonic components and the effect of unbalanced loads. Under normal operation it was demonstrated that one of the I-UPQC converters can be sized as 50\% of the generator rated power, which is an advantage for real implementation. A comparison between two ways to connect the I-UPQC to the grid, along with the wind turbine, was made. The series converter connected between the wind turbine and the parallel converter, or between parallel converter and the common connection point (PCC). It was concluded that the shunt converter connected to the generator presents better performance than the series converter due to series converter currents are less than the stator currents. Under this configuration, there is no active power current from the generator injected in the PCC during voltage sags.
Turbinas de velocidade fixa dominaram completamente o mercado atà meados de 1990 e atualmente, apesar da maioria dos aerogeradores instalados serem de velocidade variÃvel, muitos aerogeradores de velocidade fixa ainda se encontram em funcionamento. Neste contexto, este trabalho apresenta um estudo sobre a operaÃÃo coordenada de um dispositivo FACTS (Flexible Alternating Current Transmission Systems) com um aerogerador de velocidade fixa, equipado com gerador de induÃÃo gaiola de esquilo. O dispositivo FACTS aplicado baseia-se na estratÃgia de controle do Condicionador Unificado de Qualidade de Energia com topologia invertida (i-UPQC, do inglÃs, Unified Power Quality Conditioner with inverted topology), e consiste de dois conversores estÃticos na configuraÃÃo back-to-back. Um modelo foi desenvolvido no software PSCAD/EMTDC e quatro cenÃrios diferentes foram simulados e discutidos a fim de validar a teoria apresentada. A partir dos resultados de simulaÃÃo, foi analisado o desempenho do i-UPQC para melhoria da qualidade da tensÃo no Ponto de ConexÃo Comum (PCC), diminuiÃÃo das correntes harmÃnicas drenadas do aerogerador e aumento da capacidade do gerador de induÃÃo de se manter conectado durante um afundamento momentÃneo da tensÃo da rede. O i-UPQC atuou de forma satisfatÃria, pois nÃo permitiu que variaÃÃes na velocidade do vento afetassem a qualidade da tensÃo fornecida ao PCC, nem que o afundamento da tensÃo no PCC alterasse a tensÃo nos terminais do estator. Quando cargas nÃo lineares foram adicionadas no sistema, o i-UPQC manteve a corrente do estator livre das componentes harmÃnicas e desbalanÃos presentes na corrente da carga. Demonstrou-se que, em condiÃÃes normais de operaÃÃo, um dos conversores do i-UPQC pode ser especificado para 50\% da potÃncia nominal do aerogerador, o que pode representar uma vantagem do i-UPQC para o caso de uma implementaÃÃo real. Foi feita uma comparaÃÃo entre duas diferentes configuraÃÃes de conexÃo do i-UPQC com o aerogerador e a rede: ora com o conversor paralelo conectado entre o conversor sÃrie e o ponto de conexÃo comum (PCC), ora conectado entre o aerogerador e o conversor sÃrie. Concluiu-se que a configuraÃÃo com o conversor paralelo conectado ao aerogerador à mais vantajosa, pois a corrente que circula atravÃs do conversor sÃrie à menor que a corrente do estator. Nesta configuraÃÃo, nenhuma corrente referente à potÃncia ativa do aerogerador à injetada no PCC durante um afundamento de tensÃo.

Full textThe Apodi Tableland has emerged as a promising pole of irrigated fruit because of the agricultural potential of its soils. Soils of Apodi Tableland are subjected to different types of management, thus conditioning changes in their physical attributes. This work aims to evaluate physically a Cambisol cultivated with papaya (Carica papaya L.) under two tillage systems, compared to another under secondary forest. Soil samples with disturbed and undisturbed structure were collected for physical analysis, namely: texture, clay dispersed in water, bulk density, particle density, aggregate stability, organic carbon, soil water retention curve, soil air permeability and soil resistance to penetration. Clay flocculation degree, soil porosity and indices related to porous geometry and organic matter were calculated. A soil water infiltration test was performed at field. The factorial scheme was 3x3x5 (two soil management systems â papaya planted on furrow and ridge â and secondary forest; three soil layers â 0-0.1 m; 0.1-0.2 m, 0.2-0.3 m; five replications), conducted in a completely randomized design, except for the hydraulic conductivity, which adopted a factorial scheme 3x2x5 (two soil management systems and secondary forest; two tensions â 0 hPa and 5 hPa, five replications). The Kolmorogov-Smirnov Test was used to verify the data set normality, the F Test for variance analysis, the Tukey Test for means comparison (all using p-value = 0.05) and multivariate analysis techniques. It was concluded that: a) the hipothesis that the tillage systems physically worsen soil was refuted, indicating that the quality of the attributes of cultivated soil, in general, has been maintained or improved in relation to the status of the native soil; b) the decreases of the organic matter content, percentage of stable aggregates in the diameter class of 4.76 to 2.00 mm and the average diameter on the cultivated soil, although they are still far from critical limits, are indicative of the need for adoption of management practices that avoid triggering a soil degradation process; c) the quality indices were sensitive to changes caused by soil tillage systems and therefore can be used as a source for understanding the dynamics of soil physical processes in time; d) the proposed indicator for evaluating soil physical quality, Srelative, was sensitive to measure the soil response to the action on its structure.
A Chapada do Apodi vem se destacando como um promissor polo de fruticultura irrigada em virtude da potencialidade agrÃcola dos seus solos, os quais sÃo submetidos a diferentes tipos de manejo, condicionando mudanÃas em seus atributos fÃsicos. O trabalho teve como objetivo avaliar fisicamente um Cambissolo cultivado com mamoeiro (Carica papaya L.) sob dois sistemas de manejo, comparado com um sob vegetaÃÃo nativa. Foram coletadas amostras de solo com estruturas deformada e indeformada para a realizaÃÃo das anÃlises fÃsicas, a saber: granulometria, argila dispersa em Ãgua, densidade do solo e de partÃculas, estabilidade de agregados, carbono orgÃnico, curva caracterÃstica de Ãgua no solo, permeabilidade intrÃnseca do solo ao ar e resistÃncia à penetraÃÃo. Foram calculados o grau de floculaÃÃo das argilas, a porosidade do solo, Ãndices relativos à geometria porosa e matÃria orgÃnica. Em campo foi realizado ensaio de infiltraÃÃo de Ãgua no solo. Os dados experimentais foram analisados considerando o delineamento inteiramente casualizado, adotando-se para todas as anÃlises o esquema em parcela subdividida 3x3x5 (dois sistemas de manejo do solo â plantio do mamoeiro em sulco e camalhÃo â e mata nativa secundÃria; trÃs camadas de solo â 0,0-0,1 m; 0,1-0,2 m e 0,2-0,3 m; cinco repetiÃÃes), exceÃÃo para a condutividade hidrÃulica, em que se adotou o esquema fatorial 3x2x5 (dois sistemas de manejo do solo e mata nativa; duas tensÃes â 0 hPa e 5 hPa; cinco repetiÃÃes). Foram aplicados os testes de Kolmogorov-Smirnov para verificar a normalidade dos dados, o F para a anÃlise de variÃncia, o de Tukey para a comparaÃÃo de mÃdias (todos a 5% de probabilidade) e tÃcnicas multivariadas de anÃlise. Concluiu-se que: a) a hipÃtese de que os sistemas de cultivo pioram os solos fisicamente foi refutada, indicando que a qualidade dos atributos do solo sob cultivo, em geral, està mantida ou melhorada em relaÃÃo à condiÃÃo de mata nativa; b) o decrÃscimo do teor de matÃria orgÃnica, da percentagem de agregados estÃveis na classe de 4,76-2,00 mm de diÃmetro e do diÃmetro mÃdio ponderado em solo cultivado, apesar de ainda estarem distantes de limites considerados crÃticos, sÃo indicadores da necessidade de adoÃÃo de prÃticas de manejo que evitem o desencadeamento de um processo de degradaÃÃo do solo; c) os indicadores de qualidade foram sensÃveis Ãs alteraÃÃes provocadas pelos sistemas de manejo do solo e, portanto, podem ser utilizados como fonte para a interpretaÃÃo da dinÃmica de processos fÃsicos do solo no tempo; d) O indicador proposto para a avaliaÃÃo da qualidade fÃsica do solo, o Srelativo, mostrou-se sensÃvel para mensurar a resposta do solo Ãs aÃÃes sobre sua estrutura.

Full textCombustion supervision by evaluating flywheel speed variations is a common approach in the automotive industry. This often involves preliminary measurements. An adequate model for simulating flywheel speed can assist to avoid some of these preliminary measurements.
A physical nonlinear model for simulating flywheel speed based on cylinder pressure information is investigated in this work. Measurements were conducted at Scania in a test bed and on a chassis dynamometer. The model was implemented in MATLAB/Simulink and simulations are compared to measured data. The first model can not explain all dynamics for the measurements in the test bed so extended models are examined. A model using a dynamically equivalent model of the crank-slider mechanism shows no difference from the simple model, whereas a model including a driveline can explain more from the test-bed measurements. When simulating the setups used at the chassis dynamometer, the simplest model works best. Yet, it is not very accurate and it is proposed that optimization of parameter values might improve the model further. A sensitivity analysis shows that the model is fairly robust to parameter changes.
A continuation of this work might include optimization to estimate parameter values in the model. Investigating methods for combustion supervision may also be a future issue.

Full textForty-three community-living persons with stroke were recruited to participate in a six-week intervention preceded and followed by a performance- and interview-based evaluation assessing different levels of disability and functioning. HRQL was measured by the VAS of the EQ-5D.
Regression models generated cross-sectionally demonstrated that physical performance, social, and psychological functioning explained up to 90% of the variation in HRQL. A GEE model revealed that, over time, only upper extremity functioning had a significant relationship with HRQL.
Much attention has already been focused on increasing physical performance in rehabilitation. However, clinicians should consider other components that affect HRQL directly or indirectly through physical performance. Only by treating the different components of functioning at various levels can HRQL be ultimately increased.

Full text(Matilda).Cooking significantly reduced the hardness of the seeds (R= - 0.752 to - 0.89) and promoted mineral leaching (P < 0.05). The interaction between environment and genotype had a significant effect on seed size, seed coat thickness, mineral composition (Phytic acid, Ne, K+, Mg2+, Ca2+ M+, Fe2+ and CU2+) and hardness (P< 0.05). Seed coat thickness did not correlated with this rate of water uptake and cooking quality. Growing environments had a greater influence on the cooking quality than genotypes. Lentils grown at Pingaring are generally had a higher in Phyti acid content, better mineral retention and were harder in texture than those grown at Mullewa.The results of this study implicated that the peak compression force (220 N) was identified as an indicator to determine the cooking time of lentil cultivars. Texture Profile Analysis (TPA) is a useful method to evaluate various texture characteristics (hardness, cohesiveness, chewiness, springiness, gumminess and adhesiveness) of lentil cultivars. Cooking quality of lentil is significantly affected by the effect of varieties and growing locations. However, not the various biochemical compositions (phytic acid and minerals) and the thickness of seed coat have no significant effect on the cooking quality of lentil.

The recent technological developments in computers and networking have made systems, such as production systems, more vulnerable to attacks having both cyber and physical components; i.e., to cyber-physical attacks. In manufacturing, such attacks are not only capable of stealing valuable information, but can also destroy equipment, force physical product changes, alter product’s mechanical characteristics, or endanger human lives. Typically, the manufacturing industry have relied on various Quality Control (QC) tools, such as product inspection, to detect the effects caused by these attacks. However, these attacks could be still designed in a way to avoid detection by traditional QC methods, which suggests a need for new and more effective QC tools. Such new tools should be able to prevent, or at least minimize, the effects of these attacks in manufacturing. Unfortunately, almost no research has been done on using QC tools for securing production systems against these malicious attacks. Hence, the overarching goal of this work is to allow QC systems to be designed in a more effective manner to act as a second line of defense, when traditional cyber-security measures and attackers have already accessed the production system. To this end, this work focuses on: 1) understanding the role of QC systems during the attack; 2) identifying existing weaknesses in QC tools and determining the effects of exploiting them by the attack; and 3) proposing more effective QC tools, for better protection against these types of cyber-physical attacks in manufacturing.
