Full textAbstract:
Cette thèse est consacrée à l’étude de deux problèmes issus de la théorie du contrôle des EDP. Dans un premier temps, on étudie le comportement asymptotique de la solution du système de von Kàrmàn viscoélastique unidimensionnel avec retard. On montre que ce dernier est bien posé dans un espace fonctionnel convenable en utilisant la méthode de Faedo-Galerkin. Pour établir notre résultat de stabilité, on utilise la méthode de Lyapunov en construisant une fonctionnelle adéquate. Dans un deuxième temps, on étudie le problème de la contrôlabilité et de la stabilisation par le bord pour l’équation des ondes unidimensionnelle dans un domaine non cylindrique. Pour la contrôlabilité, on utilise la méthode des caractéristiques pour construire l’unique solution du problème. Nous sommes alors capables de donner l’expression explicite du contrôle pour lequel le système atteint le point d’équilibre après un certain temps. De plus, on montre que ce temps est optimal. Pour la stabilisation, nous fournissons une condition nécessaire et suffisante pour que l’énergie du système décroisse à un taux prédéterminé. De plus, l’influence de la géométrie du domaine et l’influence d’un amortisseur dépendant du temps sont clarifiées. Dans un troisième temps, on étudie la contrôlabilité par le bord de deux ´équations d’ondes couplées par un couplage d’ordre un avec coefficients qui dépendent de l’espace et du temps. On fournit une condition nécessaire et suffisante pour la contrôlabilité exacte en haute fréquences dansle cas général et pour la continuation unique dans le cas cascade<br>This thesis is devoted to the study of two problems related to the theory of control of PDE.In a first time, we study the asymptotic behavior of the solution to the one-dimensional viscoelastic von Kàrmàn system with delay. We prove that the latter system is well-posed in a suitable functional space using the Faedo-Galerkin method. To establish our stability result, we employ the Lyapunov method by using a suitable candidate functional.In a second time, we study the problem of boundary controllability and stabilization for the one-dimensional wave equation in non-cylindrical domains. For the controllability, one uses the characteristics method to build the unique solution. We will then be able to give the explicit expression of the controls for which the system reaches the equilibrium point after a certain time. Moreover, we show that this time is optimal.For the stabilization, we provide a necessary and sufficient condition that guarantees the energy decay at any desired rate. In addition, the influences of the domain geometry and time-dependent feedback are clarified. In a third time, we study the boundary controllability of two coupled one-dimensional wave equations with first-order coupling terms with coefficients depending on space and time. We give a necessary and sufficient conditions for both exact controllability in high frequency in the general case and for the unique continuation in the cascade case

Kolotkov, Dmitrii. "Nonlinear and multi-modal oscillatory processes in active regions of the solar atmosphere." Thesis, University of Warwick, 2017. http://wrap.warwick.ac.uk/93215/.
Full textAbstract:
For longer than a century, analysis of a quasi-periodic variability of the Sun on various time scales has been attracting great interest among the research community. These signals are continuously detected throughout the whole electromagnetic spectrum, and often have non-stationary oscillation periods and irregular profile shapes. The physical mechanisms responsible for such variations are usually hidden, and their revealing always require an advanced combination of powerful spectral techniques and strong theoretical foundations. This thesis considers oscillatory phenomena occurring in the solar atmosphere from these two perspectives. For the spectral analysis of solar periodicities the self-adaptive Hilbert–Huang transform (HHT) method is employed. With the statistics of coloured noises incorporated, it allowed for the detection of a long-period oscillation of a small-scale photospheric magnetic structure, whose period grows from 80 to 230 min and positively correlates with the amplitude. A multi-modal nature of the solar flare quasiperiodic pulsations was also revealed with HHT. The detected intrinsic modes have mean periods of 15, 45, and 100 s, and can be interpreted as the kink and sausage magnetohydrodynamic oscillations of a flaring loop. Analysis of much longer solar periodicities associated with the magnetic activity cycles 22, 23, and 24 was also successfully performed with HHT, revealing a broad range of intrinsic modes with periods from about a month to several years (including the 11 yr cycle). From the theoretical point of view, the one-dimensional equilibrium and dynamical models of current sheets in the corona have been developed. The equilibrium model provides an inhomogeneous distribution of macroscopic plasma parameters across the current sheet, as found for realistic physical conditions. The dynamical model describes nonlinear oscillations of the current sheet formed by the coalescence of two magnetic flux ropes. The oscillation period is found to be about the ion plasma period or longer, and is prescribed by the current sheet thickness, the plasma parameter β, and the oscillation amplitude. Analytical modelling of finite amplitude transverse oscillations in quiescent prominences situated in a magnetic field dip, is also performed in the thesis. The model is based on the line-current concept and accounts for the interaction of the prominence current with the electrically conductive photosphere. In the linear regime, the horizontal and vertical motions are considered independently, and the mechanical stability of the system is analysed. The oscillation periods are determined by the prominence current, its mass and height above the photosphere, and the properties of the magnetic dip. In the case of finite amplitudes, the horizontal and vertical modes were found to be nonlinearly coupled with each other, and a metastable equilibrium state of the prominence was revealed. The periods of nonlinear oscillations are shown to depend upon the oscillation amplitude.

Liao, Yangzhe. "System design and performance analysis of wireless body area networks." Thesis, University of Warwick, 2017. http://wrap.warwick.ac.uk/93315/.
Full textAbstract:
One key solution to provide affordable and proactive healthcare facilities to overcome the fast world population growth and a shortage of medical professionals is through health monitoring systems capable of early disease detection and real-time data transmission leading to considerable improvements in the quality of human life. Wireless body area networks (WBANs) are proposed as promising approaches to providing better mobility and flexibility experience than traditional wired medical systems by using low-power, miniaturised sensors inside, around, or off the human body and are employed to monitor physiological signals. However, the design of reliable and energy efficient in-body communication systems is still a major research challenge since implant devices are characterised by strict requirements on size, energy consumption and safety. Moreover, there is still no agreement regarding QoS support in WBANs. The first part of this work concentrates on the design and performance evaluation of WBAN communication systems involving the ‘in-body to in-body’ and ‘in-body to on-body’ scenarios. The essential step is to derive the statistical WBAN path loss (PL) models, which characterise the signal propagation energy loss transmitting via intra-body region. Moreover, from the point of view of human body safety evaluation, the obtained specific absorption rate (SAR) values are compared with the latest Institute of Electrical and Electronics Engineers (IEEE) 802.15.6 Task Group technical standard and the International Commission on Non-Ionizing Radiation Protection (ICNIRP) safety guidelines. Link budget analysis is then presented using a range of energy-efficient modulation schemes, and the results are given including the transmission distance, data rate and transmitting power in individual sections. On the other hand, major quality of service (QoS) support challenges in WBANs are discussed and investigated. To achieve higher lifetime and lower network energy consumption, different data routing protocol methods, including incremental relaying and the two-relay based routing technique are taken into account. A set of key QoS metrics for linear mathematical models is given along with the related subjective functions. The incremental relaying routing protocol promises significant enhancements in in-body WBAN network lifetime by minimising the overall communication distance while the two-relay based routing method achieves better performance in terms of emergency data transmission and high traffic condition, QoS-aware WBANs design. Moreover, to handle real-time high data transmission applications such as capsule endoscope image transmission, a flexible QoS-aware wireless body area sensor networks (WBASNs) model is proposed and evaluated that can bring novel solutions for a realistic multi-user hospital environment regarding information packet collision probability, manageable numbers of sensor nodes and a wide range of data rates.

Giusti, Andrea. "Planck stars: theory and phenomenology." Master's thesis, Alma Mater Studiorum - Università di Bologna, 2015. http://amslaurea.unibo.it/9315/.
Full textAbstract:
General Relativity (GR) is one of the greatest scientific achievements of the 20th century along with quantum theory.
Despite the elegance and the accordance with experimental tests, these two theories appear to be utterly incompatible at fundamental level.
Black holes provide a perfect stage to point out these difficulties. Indeed, classical GR fails to describe Nature at small radii, because nothing prevents quantum mechanics from affecting the high curvature zone, and because classical GR becomes ill-defined at r = 0 anyway.
Rovelli and Haggard have recently proposed a scenario where a negative quantum pressure at the Planck scales stops and reverts the gravitational collapse, leading to an effective “bounce” and explosion, thus resolving the central singularity. This scenario, called Black Hole Fireworks, has been proposed in a semiclassical framework.
The purpose of this thesis is twofold:
- Compute the bouncing time by means of a pure quantum computation based on Loop Quantum Gravity;
- Extend the known theory to a more realistic scenario, in which the rotation is taken into account by means of the Newman-Janis Algorithm.

Jifon, Francis. "Processing and modelling of seismic reflection data acquired off the Durham coast." Thesis, Durham University, 1985. http://etheses.dur.ac.uk/9315/.
Full textAbstract:
Off the Durham coast, the Permian succession above the Coal Measures contains limestones and anhydrite bands with high seismic velocities and reflection coefficients. The consequent reduction in penetration of seismic energy makes it difficult to determine Coal Measures structure by the seismic reflection method. Seismic data sets acquired from this region by the National Coal Board in 1979 and 1982 are used to illustrate that satisfactory results are difficult to achieve. Synthetic seismograms, generated for a simplified geological section of the region, are also used to study various aspects of the overall problem of applying the seismic technique in the area. Standard and non-standard processing sequences are applied to the seismic data to enhance the quality of the stacked sections and the results are discussed. This processing showed that in the 1979 survey, in which a watergun source and a 600m streamer were used, some penetration was achieved but Coal Measures resolution on the final sections is poor. The 1982 data set, shot along a segment of the 1979 line using a sleeve exploder source and a 150m streamer, showed no Coal Measures after processing. Synthetic seismograms, generated using the reflectivity method and a broadband source wavelet, are processed to confirm that a streamer with a length of 360 to 400m towed at a depth of 5-7.5m will be optimal for future data acquisition in the area. It is also shown that the erosion of the surface of the limestone lowers the horizontal resolution of the Coal Measures. Scattering

Full textAbstract:
The purpose of this research is to investigate how, to what extent and why Sierra Leone continues to struggle to turn its minerals into an engine for a sustained and inclusive economic growth and development. Consequently, the first aim of this research is to explore the evidence of two resource curse (RC) symptoms in Sierra Leone in the post-war era. Secondly, this research critically evaluates Sierra Leone’s natural resource environmental governance (NREG) agenda for the country’s mining sector, and its ability to resolve mining-induced problems. This research employed structural analysis. Consequently, it grounds Harvey’s notion of, ‘accumulation by dispossession’ in rich empirical data derived from Sierra Leone. Fieldwork was conducted in Sierra Leone: in Freetown and Kono a mining microcosm. This research employed qualitative methods. Findings from this research revealed that Sierra Leone continues to be a victim of the RC. Low taxes, tax concessions and exemptions and alleged tax evasion practices have deprived the economy of valuable development funds. Furthermore, an influx of mining companies into Kono, dislocated communities from their land. The consequences of this dislocation engendered and contributed towards the process of deagrarianisation and depeasantisation and exacerbated poverty. Findings also revealed that the NREG agenda is incapable of addressing mining-induced problems in Sierra Leone. This is because the provisions in the 2009, Mines and Minerals Act enable the dislocation of mining communities and fails to provide explicit and unambiguous guidelines for compensation and resettlement of affected communities. The subjective nature of the Environmental Impact Assessment process undermined the NREG agenda. Furthermore inadequate resources coupled with a constrained mandate undermined the effectiveness of the Agency. Although this research does not discount the importance of corruption and a lack of transparency, it argues that the prioritisation of a ‘neoliberal’ type of governance is central to the problems and issues identified.

Essa dissertação propõe uma estrutura para a GC em uma empresa de grande porte do setor alimentício que possui dezenas de fábricas espalhadas pela América Latina e emprega milhares de funcionários. Para definição da proposta, realizou-se pesquisa bibliográfica, principalmente no estudo dos fatores críticos de sucesso (FCS) para o GC conceituados por diferentes autores, e pesquisa de campo e documental, desenvolvida na empresa estudada através de visitas pré-agendadas, nas quais permitiram a caracterização e o levantamento do perfil organizacional pelo autor. Também se realizou entrevista com funcionários de diversos setores, funções e níveis hierárquicos a fim de entender a empresa sob a ótica de seus empregados. Como resultado, verificou-se que a estrutura proposta convergiu tanto para os FCS pesquisados na bibliografia quanto para os resultados da entrevista. Concluiu-se também que a gestão do conhecimento, devidamente administrada, criará condições para que a organização, corporativamente, melhore seus resultados operacionais, de forma a diminuir as discrepâncias encontradas atualmente em unidades idênticas, e conduzindo-a para uma posição estratégica superior a qual ela já se encontra<br>Companies are increasingly considering the practices of knowledge management (KM) in their strategies as a management model that can protect their organizational knowledge and generate competitive advantages for their businesses.

Quando ingenuamente joga uma pedra em uma fenda de um penhasco, ouve um barulho de jarro quebrando. Assim ocorreu a maior descoberta de textos antigos jamais feita até então – os Manuscritos do Mar Morto. Uma série de cavernas foi encontrada em seguida, das quais algumas também possuíam material manuscrito. Após isso, percebeu-se que estes manuscritos eram oriundos de um sítio arqueológico próximo, conhecido atualmente como Khirbet Qumran. O material literário que foi descoberto nestas cavernas passou desde então a ser estudado por eruditos do mundo inteiro. Entre estes manuscritos, uma parcela importante é de textos hinários que eram utilizados pela comunidade que residiu neste assentamento até pouco tempo antes da destruição de Jerusalém, em 70 d.C. Os textos hinários eram largamente utilizados pela comunidade de Qumran, com uma função importante dentro dos rituais comunitários e em manifestações pessoais de louvor a Deus. Da mesma maneira, percebemos através dos livros do Novo Testamento que nas comunidades cristãs do primeiro século, a prática do canto hinário foi uma constante. Não só suas composições hinárias, mas aspectos doutrinais destas comunidades apresentam influências consideráveis de materiais anteriores e de outras fontes contemporâneas. Antes da descoberta dos Manuscritos do Mar Morto, acreditavase que as maiores influências à literatura do Novo Testamento provinham somente da Bíblia Hebraica. Atualmente, percebemos mais do que isso. Alguns hinos e passagens...<br>A youth bedouin shepherd was searching for one of his lost animals in the area of the Judean desert, near the border of the Dead Sea, in the year of 1947. When he ingenuously threw a stone in a rift of a cliff, he heard a vessel noise breaking. Thus happened like this the largest discovery of old texts ever done until then – the Dead Sea Scrolls. A series of caves was found soon after, several of which contained hand written material. Archaeologists soon realized that these manuscripts were originating from a nearby archaeological site, known now as Khirbet Qumran. Scholars worldwide have studied the literary material that was discovered in these caves. The hymnary texts that were used by the community that resided in this settlement from before the destruction of Jerusalem in 70 A.D. are among the most priceless documents discovered. The broadly used hymnary texts of the Qumran community had a significant function in the religious and ritualistic life of the community as evidenced by the personal manifestations of praise to God in the texts. This is analogous to the practices of the early Christian communities of the first century, as described in the New Testament, in which the practice of singing hymns was a daily occurrence. In addition to containing hymnal compositions, the texts also present the doctrinal aspects of the Qumran community. The doctrine presented in the texts shows a considerable influence from older sources and contemporary sources of the Qumran community. Before the discovery of the Dead Sea Scrolls, it was believed that the largest influence to the literature of the New Testament was solely derived from the Hebraic Bible.

For the experiments 1, 2 and 3, after the processing in the different cuts, the fruits were conditioned in isopor trays involved in plastic film and submitted to different concentrations of ascorbic acid (0%, 1%, 2%, 3% and 4%); Experiment 4 - the fruits processed in cubes of 2 x 2 cm, immersed in solution of 3% of ascorbic acid, conditioned in isopor trays involved in plastic film and irradiated with different gamma radiation doses (T1 - control (0,0kGy), T2 - 0,1kGy, T3 - 0,2kGy, T4 - 0,3kGy, T5 - 0,4kGy, T6 - 0,5kGy). The fruits were irradiated in EMBRARAD, located in Cotia - SP. Apples ' Royal Gala' were used in this research, coming from the Company Agroban (Vacaria - RS). The fruits were transported to the Laboratory of Fruits and Vegetables, belonging to the 'Departamento de Gestão e Tecnologia Agroindustrial', of 'Faculdade de Ciências Agronômicas - UNESP - Campus of Botucatu, SP'. Each fruit after receiving treatment, was stored for each experiment in a cold camera to 5l1ºC and 85 - 90% of relative humidity. The evaluations were accomplished every other day, for 10 days of storage. The alterations in the quality postharvest were detected through the analyses of loss of fresh mass...

Objetivo: Quantificar a expressão de interleucina (IL)-4 e IL- 10 pelas membranas corioamnióticas de gestantes com RPM-PT e avaliar a relação dessa expressão com presença de corioamnionite. Material e Foram incluídas no estudo 30 gestantes com RPM-PT em trabalho de parto (RPM-PT em TP) e 20 gestantes com RPM-PT fora do trabalho de parto (RPM-PT fora de TP). Como grupo controle foram avaliadas 30 gestantes em trabalho de parto prematuro (TPP) e bolsa das águas íntegra. No momento da resolução da gestação, após a dequitação, foram retirados fragmentos das membranas corioamnióticas e acondicionados em RNA later para posterior quantificação do RNAm das citocinas pela técnica de PCR em tempo real. Fragmentos das membranas foram submetidos à análise histopatológica para avaliação da presença de corioamnionite. No período do estudo, a incidência de RPM-PT foi de 6,2% e de TPP foi de 5,5%. Para a IL-10, a concentração relativa de RNAm foi estatisticamente superior nas membranas corioamnióticas de gestantes do grupo RPM-PT fora de TP em relação ao grupoTPP. Em relação à IL-4 não houve diferença significativa entre os grupos estudados. A presença de corioamnionite foi de 44,0% no grupo RPM-PT e de 66,7% no grupo TPP. A análise estatística não apontou diferença significativa entre a expressão de IL-4 e IL-10, na presença ou ausência de corioamnionite, nos grupos estudados. A concentração relativa de RNAm de IL-10 é superior nas membranas corioamnióticas do grupo RPM-PT fora de TP em relação ao grupo TPP e entre os grupos RPM-PT e TPP a expressão de IL-4 é similar.

Some drip tapes that farmers can find in Brazilian Market, donþt have technical information in Portuguese language. Standards in their respective areas can be important tools for people who select, design, purchase, install, operate and evaluate irrigation equipment. 5 The ISO 9261:2004 gives mechanical and functional requirements for agricultural irrigation emitters and emitting pipes, and, provides methods for testing conformity with such requirements. It also specifies the data to be supplied by the manufacturer to permit correct information, installation and operation in the field. It is applicable to emitters, emitting and dripping (trickling) pipes, hoses, including collapsible hoses (tapes) and tubing of which the emitting units form an integral part, to emitters and emitting units with or without pressure regulation and with flow rates not exceeding 24 L.h-1 per outlet. It is not applicable to porous pipe, nor does it cover the performance of pipes as regards clogging. The carry out the resistence to tension for emitting pipe is a good tool to classify in non-reusable and reusable emitting pipes. Non-reusable emitting pipe is not intended for removal from the field and reinstallation. Reusable emitting pipe is designed for removal from the field and reinstallation with proper handling from one season to another or under other circumstances. This work was developed at the Irrigation Laboratory - UNESP to evaluate two drip collapsible hose (P2015 and Golden Drip) according to ISO 9261:2004.

Thesis: S.M., Massachusetts Institute of Technology, Department of Mechanical Engineering, 2014.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (pages 119-121).<br>This thesis introduces a method of measuring contact force with GelSight. GelSight is an optical-based tactile sensor that uses a piece of coated elastomer as the contact medium. A camera records the distortion of the elastomer during contact. This sensor can obtain a high-resolution view of the contact surface geometry, which is a breakthrough for artificial tactile sensors. In this thesis, I will introduce my work on trying to measure the contact force with GelSight. This work is based on adding markers to the elastomer surface and using them to track the planar deformation field of the elastomer surface. I derive a quantitative relationship between the surface's planar deformation field and the external contact force. I describe the development of a finite element model of the elastomer as well as the experiments on a bench-top and a portable GelSight devices. The experiments show that the contact force and the deformation field are closely related, and indicate that the method is effective in inferring the contact state under realistic conditions.<br>by Wenzhen Yuan.<br>S.M.

Thesis: Ph. D. in Architecture: History and Theory of Architecture, Massachusetts Institute of Technology, Department of Architecture, 2014.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (pages 265-287).<br>This dissertation explores the development by architects in interwar Poland of new epistemological approaches responsive to the challenges of modernity and modernization in the early twentieth century. It probes the establishment of institutional structures in higher education, publishing, and corporate life, investigating their development in relation to concomitant evolution of discourses around the role of history, architectural pedagogy, the social role of the architect, and the legal status of the architecture profession - crucial matters at the limen between the romantically glorified past and gloriously hopeful future. I argue that the robust intellectual currency ultimately shared among architects across the newly reconstituted Polish state facilitated challenges to long-standing narratives of romantic nationalism thus paving the way for a reconstruction of collective identity and consequently sophisticated contributions to cultural modernity and economic modernization. Presenting this largely untold story contributes to reevaluation of the genesis, development, and impacts of modernist culture in ostensibly peripheral locals, such as Central Europe, revealing these phenomena to be more pluralistic and nuanced than canonical historiography of modernism suggests. I present the construction of this institutional and epistemological armature as a process in three phases, with a segment of the developing network taking the leading role in each. Chapter one provides historical context and outlines a model of theory change developed by Ludwik Fleck in which social forces with particular historical contours are embodied in institutions crucial to the development of characteristic "thought styles" underlying the persistence of unique "thought collectives." Chapter two explores the newly formed Department of Architecture at the Warsaw University of Technology, showing how its faculty and students worked to form themselves into an intellectual community reimagining the historical and aesthetic foundations of Polish architecture. Chapter 3 addresses strategies for communication deployed in Polish architectural journals, where the articulation of a disciplinary identity for architecture as professionalized occupation, cultural phenomenon, and intellectual project was presented for both practitioners and a broader public. The final chapter focuses on architects' negotiation of conflicts both internally between generational groups and externally against peer engineers in the marketplace to formalize the corporate and legal organization of their profession.<br>by Matthew Benjamin Matteson.<br>Ph.

Uma norma estabelecida representa o estado da arte em sua área de atuação. A ISO 9261:2004 é uma norma internacional que orienta como avaliar e especificar gotejadores (emissores com vazão menor ou igual a 24 L.h-1) e entre outras informações, defini o que é uma mangueira gotejadora colapsável, ou fita do Inglês "tape". O ensaio de resistência à tensão conforme a ISO 9261:2004 é uma ferramenta útil para classificar um modelo de mangueira gotejadora em reutilizável e não reutilizável. A mangueira reutilizável pode ser removida do campo e ser reinstalada de uma época de cultivo para outra. A mangueira gotejadora não reutilizável não é adequada para ser removida do campo para outra reinstalação. O objetivo deste estudo foi a de aplicar a ISO 9261:2004 na avaliação de mangueiras gotejadoras colapsáveis, daqui em diante citada como mangueira (s) gotejadora (s). No Laboratório de Irrigação da Universidade Estadual Paulista "Julio de Mesquita Filho" - Faculdade de Ciências Agronômicas, ensaiou-se duas mangueiras gotejadoras de acordo com a norma ISO 9261:2004.

Some drip tapes that farmers can find in Brazilian Market, donþt have technical information in Portuguese language. Standards in their respective areas can be important tools for people who select, design, purchase, install, operate and evaluate irrigation equipment. 5 The ISO 9261:2004 gives mechanical and functional requirements for agricultural irrigation emitters and emitting pipes, and, provides methods for testing conformity with such requirements. It also specifies the data to be supplied by the manufacturer to permit correct information, installation and operation in the field. It is applicable to emitters, emitting and dripping (trickling) pipes, hoses, including collapsible hoses ("tapes") and tubing of which the emitting units form an integral part, to emitters and emitting units with or without pressure regulation and with flow rates not exceeding 24 L.h-1 per outlet. It is not applicable to porous pipe, nor does it cover the performance of pipes as regards clogging. The carry out the resistence to tension for emitting pipe is a good tool to classify in non-reusable and reusable emitting pipes. Non-reusable emitting pipe is not intended for removal from the field and reinstallation. Reusable emitting pipe is designed for removal from the field and reinstallation with proper handling from one season to another or under other circumstances. This work was developed at the Irrigation Laboratory - UNESP to evaluate two drip collapsible hose (P2015 and Golden Drip) according to ISO 9261:2004. The Golden Drip is a commercial product from South Korea and P2015 is an industrial prototype from Petroisa Brasil. Both drip tape are similar.

Quando ingenuamente joga uma pedra em uma fenda de um penhasco, ouve um barulho de jarro quebrando. Assim ocorreu a maior descoberta de textos antigos jamais feita até então - os Manuscritos do Mar Morto. Uma série de cavernas foi encontrada em seguida, das quais algumas também possuíam material manuscrito. Após isso, percebeu-se que estes manuscritos eram oriundos de um sítio arqueológico próximo, conhecido atualmente como Khirbet Qumran. O material literário que foi descoberto nestas cavernas passou desde então a ser estudado por eruditos do mundo inteiro. Entre estes manuscritos, uma parcela importante é de textos hinários que eram utilizados pela comunidade que residiu neste assentamento até pouco tempo antes da destruição de Jerusalém, em 70 d.C. Os textos hinários eram largamente utilizados pela comunidade de Qumran, com uma função importante dentro dos rituais comunitários e em manifestações pessoais de louvor a Deus. Da mesma maneira, percebemos através dos livros do Novo Testamento que nas comunidades cristãs do primeiro século, a prática do canto hinário foi uma constante. Não só suas composições hinárias, mas aspectos doutrinais destas comunidades apresentam influências consideráveis de materiais anteriores e de outras fontes contemporâneas. Antes da descoberta dos Manuscritos do Mar Morto, acreditavase que as maiores influências à literatura do Novo Testamento provinham somente da Bíblia Hebraica.

When he ingenuously threw a stone in a rift of a cliff, he heard a vessel noise breaking. Thus happened like this the largest discovery of old texts ever done until then - the Dead Sea Scrolls. A series of caves was found soon after, several of which contained hand written material. Archaeologists soon realized that these manuscripts were originating from a nearby archaeological site, known now as Khirbet Qumran. Scholars worldwide have studied the literary material that was discovered in these caves. The hymnary texts that were used by the community that resided in this settlement from before the destruction of Jerusalem in 70 A.D. are among the most priceless documents discovered. The broadly used hymnary texts of the Qumran community had a significant function in the religious and ritualistic life of the community as evidenced by the personal manifestations of praise to God in the texts. This is analogous to the practices of the early Christian communities of the first century, as described in the New Testament, in which the practice of singing hymns was a daily occurrence. In addition to containing hymnal compositions, the texts also present the doctrinal aspects of the Qumran community. The doctrine presented in the texts shows a considerable influence from older sources and contemporary sources of the Qumran community. Before the discovery of the Dead Sea Scrolls, it was believed that the largest influence to the literature of the New Testament was solely derived from the Hebraic Bible.<br>Mestre

Full textAbstract:
This dissertation demonstrates the preparation of blocky brominated syndiotactic polystyrene (sPS-co-sPS-Br) copolymers with tailored chain sequences using a simple, post-polymerization functionalization method conducted in the heterogeneous gel state, and investigates the effect of sPS reaction state and sPS/solvent gel morphology on the copolymer microstructure and thermal properties. Gel-state (Blocky) brominated copolymers were prepared from a 10 w/v% sPS/carbon tetrachloride (CCl4) gel and a 10 w/v% sPS/chloroform (CHCl3) gel in a matched set containing 6−32 mol% p-bromostyrene (Br-Sty) units. For comparison, a matched set of randomly brominated copolymers was prepared using a homogeneous solution-state (Random) reaction method and a set of brominated copolymers was prepared using a heterogenous powder-state (Powder) reaction method. The degree of bromination was evaluated using 1H nuclear magnetic resonance (NMR) spectroscopy. Powder-state bromination produced copolymers with a limited degree of functionalization of up to 12 mol% Br and required a threefold longer reaction time than the gel-state method conducted on the sPS/CHCl3 gel, demonstrating that the powder-state method is time-consuming and the dense sPS powder is incapable of producing copolymers with high Br-content. Microstructural characterization provided by 13C NMR spectroscopy, showed that bromination of sPS produces multiple peaks in the quaternary carbon region of the NMR spectrum, signifying through-bond communication between neighboring styrene and Br-Sty monomers. This work provides the first high-resolution comonomer sequencing of brominated sPS copolymers. Characterization of the quaternary carbon spectrum, assisted by band selective gradient heteronuclear multiple bond correlation (bsgHMBC) spectroscopy, electronic structure calculations, and simulated statistically random copolymer chains, revealed that each resonance peak could be assigned to a styrene or Br-Sty unit that exists in the center of a unique sequence of five monomers (i.e., a pentad) along the copolymer chain (e.g., ssssb where s = styrene and b = brominated styrene). Our comonomer sequencing method demonstrated that the Blocky and Powder copolymers have block-like character. Remarkably, the Blocky copolymers exhibit notably higher degrees of blockiness and larger fractions of sssss and bbbbb pentads at low Br contents (i.e., 32 mol% Br), relative to the Powder copolymers, confirming their blocky microstructure. Quenched films of the Blocky copolymers, analyzed using ultra-small-angle (USAXS) and small-angle X ray scattering (SAXS), show micro-phase separated morphologies that are reminiscent of conventional block copolymer phase behavior, supporting that the Blocky copolymers contain distinct segments of pure sPS and segments of randomly brominated sPS. Crystallization behavior of the copolymers, examined using differential scanning calorimetry (DSC), demonstrates that the Blocky copolymers are more crystallizable and crystallize faster at lower supercooling compared to their Random analogs. Simulations of blocky copolymers were developed based on the semicrystalline gel morphology to rationalize the effect of gel-state functionalization on copolymer microstructure and crystallization behavior. The simulations confirm that restricting the accessibility of the brominating reagent to monomers well removed from the crystalline fraction of the gel network produces copolymers with a greater prevalence of long runs of pure sPS that is advantageous for preserving desired crystallizability of the resulting blocky copolymers. To investigate the effect of sPS/solvent gel morphology on copolymer microstructure and crystallization behavior, the sPS/CCl4 and sPS/CHCl3 copolymers were compared directly. Characterization of the sPS/solvent gels using USAXS/SAXS, revealed that the gels exhibit different morphologies and average lamella thicknesses. Microstructural analysis showed that the sPS/CHCl3 copolymers contain larger fractions of sssss pentad and a greater degree of blockiness. The sPS/CHCl3 copolymers contain larger phase domains, supporting that these copolymers contain longer distinct segments of pure sPS and randomly brominated sPS in a multiblock-like microstructure. In addition, the sPS/CHCl3 copolymers are more crystallizable during conditions of rapid cooling and crystallize faster at low supercooling relative to their sPS/CCl4 analogs. Simulated average chains of the Blocky copolymers, generated from the empirical pentad sequence distributions, provide strong evidence that the runs of pure sPS in the Blocky copolymers originate from the crystalline stems within the crystalline lamellae. Thus, the simulations support that semicrystalline blocky brominated copolymers with tailored chain sequences, phase behavior, and crystallization properties and can be prepared simply by changing the gelation solvent.<br>Doctor of Philosophy<br>Block copolymers are a class of large molecules (polymers) that are made up of two or more chains (blocks) of different smaller units (monomers) linked together at one of each of the chain ends. When the monomers that make up each block have distinctly different chemical properties, the blocks may be capable of self-assembling into well-ordered physical structures, which give the block copolymer unique material properties that are different, and often better than the properties of the individual blocks alone (homopolymers). Block cop
olymers have thus received tremendous attention with respect to controlled preparation, tailored structure development, and customized physical properties, for their potential use in self-assembled, nanostructured materials. Nevertheless, the generally difficult procedures and conditions required to make (polymerize) block copolymers with controlled sequences limits the scope of their commercial application. As an alternative to conventional polymerization methods, this dissertation demonstrates a comparatively simple physical method to make copolymers that contain significantly non-random (blocky) monomer sequences, starting with a homopolymer and using a reagent to modify units along the polymer chain. This post-polymerization method is conducted in the homopolymer’s gel state, in which segments of the homopolymer chains are effectively shielded from the reagent. The homopolymer, syndiotactic polystyrene (sPS), was used as a model to conduct a fundamentical investigation into the effects of the polymer reaction state, i.e., gel, solution, or powder, and the gel structure (morphology) on the copolymer structure and properties. The gel-state was found to produce copolymers with a high degree of modification and a greater degree of blockiness than the solution-state and powder-state. Copolymers prepared from the gel state exhibited properties that are characteristic of conventional block copolymers. Furthermore, using the gel-state method, blocky copolymers with tailored chain sequences and properties were prepared by simply changing the gel morphology. Thus, reaction in the gel-state is demonstrated as a simple physical approach to polymer design and synthesis that will be useful in the development of next-generation functionalized materials through the modification of lowcost commodity polymers. As an advancement to the manner in which nanostructured materials are created, these tailored materials will greatly enhance the convenience of block copolymers for a wide variety of applications including structural and biomechanical materials, and polymeric membranes for energy conversion and water purification systems.

Asimismo, a partir de la Teoría de Áreas Monetarias Óptimas se elabora un índice agregado con el objetivo de conocer cuál de los tres bloques regionales está más preparado para avanzar hacia una mayor integración regional.<br/><br/>Los resultados sugieren que en la actualidad, de los tres procesos de integración regional analizados, el Mercado Común Centroamericano muestra unas condiciones más favorables para profundizar hacia estadios más avanzados de integración regional. Asimismo, desde su situación actual cercana a una unión aduanera, el MCCA ha registrado mejoras significativas en los últimos años en los indicadores de integración regional analizados. Aún así, a pesar de este progreso, el grado de cumplimiento de los requisitos asociados a un área óptima monetaria, deseables para profundizar hacia etapas de integración más avanzadas como una unión monetaria, todavía puede considerarse en la actualidad como débil, tanto para el MCCA como para el resto de procesos analizados.<br>In the middle of the decade of the nineties Latin America experienced a strong impulse of the agreements of integration between countries of the region and with regard to third partners. As a result of the process, already existing agreements, such as the Central American Common Market (CACM) or the Andean Community, became stronger and new agreements of integration were signed, such as the Common Market of the South (MERCOSUR).<br/><br/> The aim of this research focuses on analyzing the three existing processes of integration in Latin America. Some criteria and variables described in the literature on Optimum Currency Areas will be used in order to evaluate the degree of readiness shown by the partners of each Latin American block to go more deeply into their process of regional integration. Likewise, an index will be elaborated from the Optimum Currency Areas Theory with the aim of knowing which of the three regional blocks is more prepared to advance towards a deeper regional integration.<br/><br/>The results suggest that, at present, from the three processes of regional integration analyzed, the Central American Common Market shows more favourable conditions to reach more advanced stages of regional integration. Likewise, from its current stage of customs union, the CACM has made significant improvements in recent years with respect to regional integration indicators. Nonetheless, in spite of this progress, the degree of compliance with the requirements of the optimum currency area, which are advisable in order to advance towards a stage of integration of monetary union, may currently still be considered weak, both for the CACM and for the rest of the analyzed processes.

Full textAbstract:
This research project investigates the practice of school guidance in secondary schools, with
special reference to Soweto.
The research was prompted by a number of problems and questions such as the following:
With all good and ideal aims of school guidance, why is it that present-day school-going
youths are the way we find them? For example, why are black youths so militant, rebellious
and unrealistic? Why are they not interested in what the community used to boast about
and pride themselves on, such as education, good behaviour, respect, respect of one
another's properties, the norms and values of the community and above all, preservation of
life?
From the above statement of the problem it becomes clear that this research can not
address all the questions stated above. However a portion or section of them will receive
some attention in accordance with the aims of this particular research project, namely:
to determine the practice of school guidance in secondary schools in Soweto;
to determine what the psychological services section of the Johannesburg Region
does about the situation; and
to give hints and guidelines as to what action plans may be implemented to improve
school guidance teaching in secondary schools in Soweto.
A greater understanding of school guidance programmes of the Department of Education
and Training was necessary, together with an insight into the guidance programmes of other
education systems in South Africa. This resulted in a thorough and in-depth literature study
of school guidance of the whole education system of the Republic of South Africa. In the
empirical research that followed, various questionnaires were devised and given to
principals, guidance teachers and members of the EAS with a request to complete the items
thereof anonymously. The SAS-computer programme was applied to determine the
frequencies and percentages for each question.
A complete analysis of the investigation results indicated that the school guidance
programme of the Department of Education and Training was not used by all secondary
schools in Soweto. Some secondary schools hardly teach the subject. From a number of
schools it became clear that the Teachers' Union rejected school guidance since it is a non-examination
subject and as such a waste of pupils' and teachers' time, which could be used
for more important subjects, i.e. examination subjects.
Finally the researcher gave some hints, suggestions and recommendations to all parties
concerned with the teaching of school guidance with special reference to secondary school
pupils in Soweto and in general. It is hoped that these recommendations will be studied,
implemented and improved for the benefit, progress and support of the child.<br>Thesis (MEd (Voorligting))--PU vir CHO, 1995

Full textAbstract:
Includes bibliographical references.<br>[Background] Research in adults and older children has shown an association between Mycobacterium tuberculosis and helminth infection, with those infected with helminths at greater risk of tuberculosis. This association is believed to be on the basis that chronic helminth infection can result in a functional impairment of the immune response that is necessary to clear or control infection by Mycobacterium tuberculosis (Elias et al. 2001; Rook et al. 2006; Fincham 2001). It is thus possible that the introduction of regular deworming programmes in a vulnerable population of children under the age of five years could assist their immune systems to ward off tuberculosis infection and reduce the risk of tuberculosis disease in such a population. A randomised controlled trial to compare two methods of administering bacille Camlette-Guerin (BCG) vaccination to newborns from a high tuberculosis risk population provided an opportunity to test this hypothesis in a sub-study. [Objective] The objective of this study is to determine if young children in a high-risk tuberculosis population who have been vaccinated with BCG at birth and have been treated for helminth infection are at lower risk of tuberculosis disease than children who have been vaccinated with BCG at birth but not treated for helminth infection. [Method] A case control study nested within a cohort recruited for a separate randomised control trial to compare two methods of administering BCG vaccination was carried out. Children who presented to their local clinic or hospital with symptoms of tuberculosis or a history of exposure to tuberculosis were admitted to a case verification (CV) ward for investigation of tuberculosis. Investigation of tuberculosis included a detailed history, including past helminth treatment, physical examination, tuberculin skin test, chest radiograph, gastric washing and induced sputum for culture of tuberculosis and clinical examination. A diagnostic algorithm was developed by specialist physicians and biostatisticians to classify the children into one of five tuberculosis categories. A total of 510 children (median age 18.13 months) were included in the primary analysis of this case control study. Those defined as cases were the 328 classified as "definite or probable TB" and 182, classified as "not TB", comprised the control group. Those classified as "possible TB" or "unlikely TB" were excluded. A secondary analysis was performed that included the 337 children who had been classified as "unlikely TB" with the controls resulting in a total of 847 children (median age 18.37 months). The 328 children classified as "definite or probable TB" were defined as cases and the 519 classified as "unlikely or not TB" comprised the control group. Univariate analysis was used to explore a possible relationship between tuberculosis and helminth treatment using all the variables in the sub-study (n=510 primary analysis; n=847 secondary analysis). For both the primary and secondary analysis a multivariate logistic regression model was built using a reduced sample that had a complete set of data for all the variables: primary analysis (n=435); secondary analysis (n=724). This final model was then fitted on a more complete sample as the final variables selected had fewer missing data for the observations: primary analysis (n=493); secondary analysis (n=822). [Result] A total of 35.69% of the study sample in the primary analysis had been treated for helminth infection. The proportion of children who had been treated for helminth infection was similar in the cases and controls (35.98% and 35.16% respectively). Univariate logistic regression showed no association between tuberculosis and treatment for helminth infection: [odds ratio (OR) 1.04; 95% confidence interval (CI) 0.71 - 1.51]. Multivariate analysis adjusted for the effect of nutritional status, recorded as height for age z score (haz), number of occupants sharing the same dwelling as the child, gender and birth site showed a similar result: (OR 1.03; 95% CI 0.69 " 1.53). The OR is very close to 1 with a 95% CI that includes 1, which indicates that there is not a statistically significant association between tuberculosis and helminth treatment. In the secondary analysis, a total of 38.61% of the study sample had been treated for helminth infection. In this analysis the proportion of children who had been treated for helminth infection showed a difference between the cases and controls (35.98% and 40.27% respectively). Univariate logistic regression showed a 17% relative reduction in tuberculosis odds but this was not a statistically significant result: (OR 0.83; 95% CI 0.63 " 1.11). Multivariate analysis adjusted for the effect of haz, number of children sharing the same dwelling as the child and gender, showed a similar result: (OR 0.85; 95% CI 0.63 " 1.15). [Conclusion] The primary analysis of this observational study does not support the hypothesis that helminth treatment reduces the risk of tuberculosis disease in young children in a high-risk tuberculosis population. Although the secondary analysis showed a 15% relative reduction in tuberculosis odds after adjusting for the effect of haz, number of occupants sharing the same dwelling as the child and gender, this was not a statistically significant result. [Final Conclusion] This study does not support the hypothesis that helminth treatment reduces the risk of tuberculosis disease in young children in a high-risk tuberculosis population.

En esta tesis doctoral se aborda el problema del control predictivo sujeto a restricciones definidas como la unión no convexa de varios poliedros. Los controladores propuestos son de utilidad, por un lado, para procesos que presentan de manera natural restricciones de dicha forma y, por otra parte, como una alternativa al control predictivo no lineal cuando períodos de muestreo bajos no permiten la aplicación de programación no lineal.
En los primeros capítulos del trabajo se demuestra la existencia de una solución explícita a los problemas de optimización que aparecen al plantear este tipo de controladores predictivos. Dicha solución es afín a tramos definidos mediante desigualdades lineales y cuadráticas. Se introducen dos metodologías diferentes para la obtención de esta solución explícita: la metodología de intersección, división y unión y la de la envolvente convexa.
La primera de estas metodologías se basa en formular subproblemas con las restricciones convexas cuya unión forma las restricciones originales y obtener la solución explícita del problema original a partir de las soluciones de dichos subproblemas.
La segunda metodología planteada se basa en el cálculo de la envolvente convexa de los conjuntos de restricciones y la obtención de la solución explícita del problema convexo definido por estas nuevas restricciones. Se demuestra como parte de las regiones de la solución explícita del problema original coinciden con las del nuevo problema, y se propone un procedimiento para identificarlas y obtener el resto de regiones, completando la solución explícita buscada.
Se estudian también algoritmos eficientes para la implementación en línea de leyes de control explícitas como las obtenidas. En particular, se propone un algoritmo basado en un árbol binario de una partición lineal y una comparación de índices de costes en las regiones en las que sea necesario.<br>Pérez Soler, E. (2011).

Gli investimenti diretti esteri, o IDE, rappresentano uno dei metodi attraverso cui le imprese si internazionalizzano, ossia si espandono attraverso i confini nazionali. Molte teorie sono state avanzate negli anni per cercare di offrire una spiegazione adeguata del fenomeno e, quella che meglio le raccoglie, è rappresentata dal paradigma eclettico di Dunning (1976). In realtà, questa teoria risulta valida se si considerano gli IDE provenienti dai paesi sviluppati, mentre per quelli realizzati dalle economie emergenti e in via di sviluppo devono essere utilizzate teorie differenti. Per un’economia come la Cina la questione è ancora più spinosa vista la particolarità degli IDE in uscita del paese. In particolare, sembra che non vi sia una teoria generale in grado di fornire una spiegazione esaustiva del fenomeno. Tuttavia, data la grande influenza del governo cinese in materia economica e quindi anche in materia di IDE, la teoria istituzionale sembra spiegare gran parte degli investimenti realizzati dalla Cina nel corso del tempo. Negli ultimi anni la Cina si è impegnata ad investire nei paesi coinvolti nell’iniziativa “One Belt One Road” (yi dai yi lu 一带一路), lanciata nel 2013 dal presidente Xi Jinping, e le imprese cinesi sono ancora una volta spinte a realizzare IDE seguendo gli scopi e le politiche messe in atto dal governo.

Previous issue date: 2014-08-18<br>Blogs showed up firstly as virtual publishing tool of the daily activities content of its founders, variation of writing diary, which is based on fast refresh and microcontent frequent publishing tool. Resulting from new configurations of society from the emergence of information and communication technologies, these tools transform
social relations conducted virtually. The femininity, while the constitution from the
genre, it becomes subjective synthesis of subjects in a social spaces that includes
virtual. In this sense, it is aimed to analyze the constitution of contemporary femininity through in-depth research of how a group of assiduous readers of blogs produce meanings about themselves and their social relations, especially in access to virtual organizations. A qualitative research with an ethnographic approach was the
methodological bases, with data collected from observation techniques and semistructured
interviews. The results indicate the female blog as a business organization, a profile of readers of these spaces with common interests and characteristics, besides femininity as a multifaceted complex of close and distant characteristics of women s old public roles.<br>Os blogs apresentaram-se, em princípio, como ferramenta de publicação virtual do

Previous issue date: 2015-01-27<br>This work presents a block-loading hybrid approach to solve the Container Loading Problem. The general idea behind the proposed algorithm is to decompose this classic Cutting and Packing problem into two subproblems, namely, a three-dimensional problem of generating a set of blocks of boxes and a two-dimensional problem of positioning a subset of these blocks on the floor of the container. On the one hand, the block generation phase is completely deterministic. Constructive algorithms to accomplish this task have been recently proposed. On the other hand, the positioning phase is non-deterministic. It comprises the Generate-and-Solve methodology, a hybrid optimization framework that combines a metaheuristic engine with an exact solver. Computational experiments performed on benchmark problem instances show that hybrid approach presents very competitive results compared to those found by state-of-the-art algorithms, obtaining in average a space utilization of 93.49% for the instances under investigation. Regarding only the best solution found for each instance, the space utilization was of 94.13% in average. In particular, for instances with a few number of box types, the proposed approach outperformed the best results reported in the literature in several test cases.
Key-words: Combinatorial Optimization. Cutting and Packing. Container Loading. HybridMetaheuristics.<br>Este documento apresenta uma abordagem híbrida de posicionamento de blocos para resolver o Problema de Carregamento de Contêiner. A ideia central do algoritmo proposto é decompor esse clássico problema de Corte e Empacotamento em dois subproblemas: um problema de empacotamento tridimensional que objetiva gerar blocos de caixas; e um problema de posicionamento bidimensional no piso do contêiner que busca maximizar o volume ocupado por um subconjunto desses blocos. Por um lado, a fase de geração de blocos é completamente determinística. Algoritmos construtivos que realizam essa tarefa têm sido recentemente propostos. Por outro lado, a fase de posicionamento de blocos é não-determinística. Esta compreende a metodologia híbrida Gerar-e-Resolver, que combina uma metaheurística com um modelo exato. Experimentos computacionais realizados em bibliotecas de testes da literatura mostram que a abordagem híbrida apresenta resultados bastante competitivos em relação àqueles do estado da arte, alcançando aproveitamento médio de 93,49% do espaço do contêiner para as instâncias estudadas. Considerando apenas a melhor solução encontrada para cada instância, o aproveitamento médio foi de 94,13%. Em particular, para instâncias com poucos tipos de caixas, a abordagem superou os melhores resultados conhecidos na literatura em diversos casos de teste.

Full textAbstract:
The UHE Passo Real reservoir, founded in 1973 (158,0 MW capacity), with a flooded area of 221 km2 (CEEE, 2008), presents different types of water and an intense agricultural exploitation in the uptake area. In this study, we aimed at interpreting, analyzing and correlating soil use and soil cover in distinct uptake watersheds and agricultural periods with TSS concentration and Secchi depth in different parts of the reservoir. The soil maps showed the three watersheds that flow into the reservoir:
Jacuí, Jacuí-Mirim and Ingaí. In these maps there were the vegetative development period in March/2009 and the post-harvest period in May with exposed soil. TM Landsat 543/RGB images were used to identify the kinds of soil use. The categories of soil use were: forest areas, cultures, field,exposed soil and water. The TSS variable (using a filtering method) was measured in 22 points
(February, April and June/2009) in four samples: Jacuí, Jacuí Mirim, Ingaí and the main reservoir axis. In the images classification, the culture category was higher in the three watersheds in March: Jacuí Mirim 61,46% (total area =157.182,75 ha), Ingaí 56,51% (114.671,16 ha) and Jacuí 49,55% (423.430,47 ha). In May, the category of exposed soil was higher: Jacuí Mirim 75,55%, Ingaí 68,78%
and Jacuí 65,77%. The highest average TSS was found in June (higher precipitation) in the Jacuí sample (Ma= 9,33 mg/L). The low TSS values were frequently found in February, for example, Jacuí sample (Ma=4,33mg/L). The data from SD samples were coherent with TSS data considering that water transparency was higher when the sediments concentration was lower. It was found that soil use and soil cover in the studied area are predominantly rural, mainly due to soybean and corn crops in
February and the beginning of winter pasture in May. Even if Jacuí Mirim and Ingaí watersheds presented a higher percentage of exposed soil in May, the Jacuí watershed presents higher TSS flush and TSS concentrations because of a larger uptake area and a lower aquatic flow volume. Overall, the aquatic dynamics at the UHE Passo Real is related to the water flow from the uptake watersheds and it
suggests distinct aquatic compartments that result in different colors of water.<br>O reservatório da UHE Passo Real, inaugurado em 1973 (capacidade 158 MW) e área inundada de 221 km2 (CEEE, 2008) apresenta diferentes tipos de água e uma intensa exploração agrícola na área de captação. Os objetivos da pesquisa compreenderam a interpretação, análise e relação do uso e cobertura da terra em distintas bacias de captação e fases agrícolas com a concentração dos sólidos em
suspensão (TSS) e a profundidade do Disco de Secchi (DS). Os mapas de uso da terra caracterizaram as três principais bacias de captação que deságuam no reservatório: Jacuí, Jacuí-Mirim e Ingaí. Esses mapas contemplaram a fase do desenvolvimento vegetativo das culturas agrícolas em março/2009 e a fase pós-colheita em maio com domínio de solo exposto. Imagens de satélite TM Landsat 543/RGB
foram utilizadas para identificar as formas de uso da terra. As classes de uso foram assim definidas: áreas florestais, culturas, campo, solo exposto e água. A variável TSS (processada pelo método da filtragem) foi medida em 22 pontos (fevereiro, abril e junho/2009) separados em quatro grupos amostrais: grupo Jacuí, Jacuí Mirim, Ingaí e eixo principal do reservatório. Na classificação das imagens a classe cultura destacou-se nas três bacias em março: 61,46% Jacuí Mirim (área total da bacia=157.182,75 ha), 56,51% Ingaí (114.671,16 ha) e 49,55% Jacuí (423.430,47 ha). Em maio, a classe solo exposto sobressaiu-se com 75,55% na bacia do rio Jacuí Mirim, 68,78% no Ingaí e 65,77%
no Jacuí. A maior média dos valores de TSS foi encontrada em junho (maior média de precipitações) para o grupo amostral Jacuí (Ma= 9,33 mg/L). Os valores baixos de TSS foram registrados, em geral, em fevereiro, a exemplo do grupo amostral Jacuí (Ma=4,33mg/L). Os dados dos grupos amostrais do DS apresentaram consistência com os dados do TSS uma vez que a transparência da água foi maior na
medida em que a concentração de sedimentos foi menor. Observou-se que os usos e coberturas da terra na área de estudo são predominantemente rurais, principalmente pelo cultivo da soja e do milho em fevereiro e início do plantio das pastagens de inverno em maio. Embora as bacias dos rios Jacuí
Mirim e Ingaí apresentaram maiores porcentagens de solo exposto em maio, na bacia do rio Jacuí registrou o maior efeito do sistema terrestre sobre o aquático com a ocorrência de maiores concentrações de TSS. Isto deve-se ao efeito de maior área de captação e menor volume do compartimento aquático de deságüe. Sobretudo, a dinâmica que ocorre no ambiente aquático do reservatório da UHE Passo Real está relacionado com a entrada de água das bacias de captação e
sugerem distintos compartimentos aquáticos pelo modo mistura que resultam diferentes colorações na água.

Previous issue date: 2017-02-06<br>Não recebi financiamento<br>The Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) authored
by Mark Sundberg provides a systematic assessment for children with autism and similar
delays and has become a frequent tool among those who gives consultations in this área.
Divided into five components, the VB-MAPP evaluates samples of the child’s verbal
repertoire from 170 developmental milestones presented in three levels (0 -18 months, 18-30
months and 30-48). The aim of this study was to translate and adapt the VB-MAPP to the
Portuguese language and propose a way to qualify professionals to implement it properly.
Study 1 translated and adapted to Portuguese Chapters 1 to 6 and the corresponding protocol
scoring form. Study 2 tested the effect of a Behavioral Skill Training to improve the
performance of the professionals in conducting the VB-MAPP. Items from a list of skills
were used to measure the performance of each participant in specific tasks (Level 1, 2 and 3)
of this assessment tool. The study consisted of three phases: pretest, training and posttest.
Ten participants were divided into two groups: control and experimental. Both groups
performed the pretest and posttest, but the training was only mandatory for the experimental
group. In the pretest phase all participants received the Portuguese version of The VBMAPP
and had to assess one child each. Training phase was composed of a BST package
(instruction, modeling, reharsal and feedback). Only Level 1 and 2 tasks were taught. Both
groups repeated the assessment in the posttest phase, however, the experimental group had
an additional task: implementing the Level 3 tasks of the VB -MAPP. Still in the posttest
phase, two participants (P3 and P6), presenting lower overall performances than the other
participants of the experimental group, were selected for five additional posttest sessions.
The results showed that all participants in the experimental group developed skills to
implement The VB-MAPP regarding Level 1 and 2 tasks. About the performance of the
experimental group in Level 3 tasks, it was possible to say that generalization occurred for
some, but not all behaviors. The results were higher than the pretests, but lower when
compared to the Level 1 and 2 tasks. Among the factors that may have contributed to this
partial result we highlight: (1) Level 3 tasks are more complex than the Levels 1 and 2 and
may require evaluators with more experience (2) only some milestones were selected for
Level 3 testing and not all of them. As for participants P3 and P6, after a total of six posttest
viii
sessions, they maintained the percentage of correct answers higher than 90% for Level 1 and
2 tasks and 85% for Level 3 tasks.<br>O Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) de autoria
de Mark L. Sundberg oferece uma avaliação sistematizada para crianças autistas ou com
atrasos similares e se tornou um instrumento de uso frequente entre aqueles que planejam e
implementam atendimentos nessa área. Dividido em cinco componentes, o VB-MAPP
avalia uma amostra do repertório verbal da criança a partir de 170 marcos de
desenvolvimento que são apresentados em três níveis (0 -18 meses; 18-30 meses e 30-48). O
objetivo do presente trabalho foi realizar a tradução e adaptação do VB-MAPP para o
português, bem como, propôr uma forma de capacitar profissionais para implementá-lo
adequadamente. O Estudo 1 traduziu e adaptou para o português o VB-MAPP manual
capítulos 1 ao 6 e o protocolo de registro correspondente. As etapas envolveram a
participação de dois tradutores independentes, avaliação de especialistas e estudo piloto. O
Estudo 2 testou o efeito de um treino de habilidades comportamentais (Behavioral Skill
Training- BST) para aprimorar o desempenho de profissionais da área da pedagogia e
psicologia na implementação do VB-MAPP. A variável dependente foi a porcentagem de
acertos de uma lista de itens, chamada de Avaliação de Desempenho, que serviu de
parâmetro para mensurar as habilidades de avaliador dos participantes em tarefas de Nível 1,
2 e 3 do VB-MAPP. O estudo foi composto por 3 fases: pré-teste, treinamento e pós-teste.
Dez participantes foram divididos em dois grupos: controle e experimental. Ambos os
grupos particiaram da fase de pré-teste e pós- teste, porém, o treinamento foi obrigatório
para o grupo experimental. Na fase do pré -teste todos receberam a versão adaptada para o
português do VB-MAPP e cada participante avaliou uma criança. Depois, somente o grupo
experimental passou pela fase de treinamento, sendo exposto a um pacote BST. O BST,
composto por instrução, modelação, ensaio e feedback, foi a variável independente Somente
habilidades de Nível 1 e 2 foram ensinadas. Na fase do pós -teste os dois grupos repetiram a
avaliação do pré-teste com a mesma criança, porém, o grupo experimental teve uma tarefa
adicional: implementar tarefas de Nível 3 do VB MAPP não ensinadas durante o
treinamento. Nessa etapa foi observado a eficácia do treinamento em promover
generalização das habilidades de avaliador para as tarefas de Nível 3. Ainda na fase de pósteste,
dois participantes (P3 e P6), apresentando desempenhos gerais inferiores aos outros
vi
participantes do grupo experimental, foram selecionados para 05 sessões adicionais de pósteste
e avaliaram novas crianças. Os resultados do primeiro pós-teste mostraram que todos
os participantes do grupo experimental desenvolveram as habilidades de avaliador esperadas
para implementar o VB-MAPP depois do treinamento, indicando a eficácia do BST. Em
relação ao desempenho nas tarefas de Nível 3, foi possível dizer que ocorreu generalização
para alguns comportamentos, mas não todos. Os resultados foram superiores aos do pré –
teste, mas inferiores quando comparados com os desempenhos de Nível 1 e 2. Entre os
fatores que podem ter contribuído para esse resultado parcial destacamos: (1) as tarefas de
Nível 3 são mais complexas que as dos Níveis 1 e 2 e podem exigir avaliadores com maior
experiência nesse tipo de tarefa (2) apenas alguns itens ou marcos foram selecionados para a
testagem do Nível 3 e não a totalidade deles. Quanto aos participantes P3 e P6, após um total
de seis sessões de pós- teste, mantiveram a porcentagem de acertos superior a 90% nas
tarefas de Nível 1 e 2 e 85% de acertos nas tarefas de Nível 3.

Full textAbstract:
This thesis investigates techniques for the solution of partial differential equations
(PDE) on advanced parallel architectures comprising central processing units (CPU)
and graphics processing units (GPU). Many physical phenomena studied by scientists
and engineers are modelled with PDEs, and these are often computationally expensive
to solve. This is one of the main drivers of large-scale computing development.
There are many well-established PDE solvers, however they are often inherently
sequential. In consequence, there is a need to redesign the existing algorithms, and
to develop new methods optimised for advanced parallel architectures. This task is
challenging due to the need to identify and exploit opportunities for parallelism, and
to deal with communication overheads. Moreover, a wide range of parallel platforms
are available — interoperability issues arise if these are employed to work together.
This thesis offers several contributions. First, performance characteristics of hybrid
CPU-GPU platforms are analysed in detail in three case studies. Secondly, an
optimised GPU implementation of the Preconditioned Conjugate Gradients (PCG)
solver is presented. Thirdly, a multi-GPU iterative solver was developed — the
Distributed Block Direct Solver (DBDS). Finally, and perhaps the most significant
contribution, is the innovative streaming processing for FFT-based Poisson solvers.
Each of these contributions offers significant insight into the application of advanced
parallel systems in scientific computing. The techniques introduced in the case
studies allow us to hide most of the communication overhead on hybrid CPU-GPU
platforms. The proposed PCG implementation achieves 50–68% of the theoretical
GPU peak performance, and it is more than 50% faster than the state-of-the-art
solution (CUSP library). DBDS follows the Block Relaxation scheme to find the
solution of linear systems on hybrid CPU-GPU platforms. The convergence of DBDS
has been analysed and a procedure to compute a high-quality upper bound is derived.
Thanks to the novel streaming processing technique, our FFT-based Poisson solvers
are the first to handle problems larger than the GPU memory, and to enable multi-
GPU processing with a linear speed-up. This is a significant improvement over the
existing methods, which are designed to run on a single GPU, and are limited by
the device memory size. Our algorithm needs only 6.9 seconds to solve a 2D Poisson
problem with 2.4 billion variables (9 GB) on two Tesla C2050 GPUs (3 GB memory).

Os procedimentos empregados no terminal portuário foram desmembrados em subsistemas operacionais e econômicos com o intuito de classificar os entraves dentro de uma organização hierárquica. Partiu-se do principio de que, em seu processo evolutivo, os terminais portuários incorporaram elementos diferenciados e restrições de ambiência, transformando-se em organizações complexas com sistemas operacionais únicos. A partir da abordagem sistêmica por atividade, concluiu-se que, por meio do reducionismo, a análise de processos e a padronização de procedimentos são ferramentas viáveis para comparar segmentos operacionais; é possível até, em alguns casos, obter novos marcos de referência. Desta forma, concluiu-se que a definição de uma plataforma de análise facilita a gestão, a programação de operações e a hierarquização das áreas portuárias. _________________________________________________________________________________ ABSTRACT<br>In this thesis the general theory of systems and the process analysis approach were used to assess the operations of a container terminal in Brazil and identify barriers to the use of best practices. The procedures applied within the container terminal were separated into operational and economic subsystems in order to classify these barriers within a hierarchical organization. It was assumed that during their development port terminals have incorporated various elements and environmental restrictions, becoming complex organizations with unique operating systems. The reductionist and systemic analysis of the activities concluded that process analysis and the standardization of procedures are feasible tools for use when comparing operating segments and can, in some cases, lead to the definition of new benchmarks. The main conclusion is that the use of an analytical platform simplifies management, operational programming and the classification of port areas within a hierarchy.
