This research examines Subscription Video On-Demand (SVOD) using Netflix as one of the main examples that has seen a dramatic increase in usage in recent years compared to the traditional way of viewing content through television.
Using focus group sessions and an online survey, a qualitative analysis approach is used by way of a thematic analysis to elaborate and gain insight into the phenomenon of SVOD within our society which has allowed viewers to alter time shifting and self-scheduling habits. Watching online film and television over the internet, forces the breakdown of the traditional value chain of viewing methods as well as consumption of it.
This research aims to narrow this research gap surrounding SVOD. The results will be used to add value to the research area of this growing and changing phenomenon of online TV consumption with SVOD.Aquesta recerca estudia el vídeo a la carta de pagament (SVOD, en anglès) a partir de l'exemple de Netflix, el qual ha vist un increment considerable de consum al llarg dels últims anys, especialment comparat amb els mitjans de comunicació tradicionals. A través de focus group i una enquesta en línia, es fa una anàlisi qualitativa que parteix d'un estudi temàtic, a fi d'elaborar i obtenir una idea del fenomen de l'SVOD dintre de la nostra societat. Aquest fenomen ha permès als espectadors alterar els hàbits d'horari d'ús i d'autoprogramació. Veure pel·licules i televisió a través d'internet força a trencar la cadena tradicional de valor dels mètodes de visionat així com el consum dels mateixos.

The purpose of this thesis is to examine the difference between SVO and OVS sentences in spoken Russian, which is a language with flexible word order although the basic order is SVO. Two experiments were conducted to understand the nature of intonation. Experiment 1 shows that the Subject appears as kontrast in OVS
sentences, and as background in SVO sentences. The F0 curve rises in the Object position when the Subject is kontrast in OVS sentences.
The analysis of the results of Experiment 2 shows that the initial element of the sentence plays an important role in intonation. When it is kontrasted, it always has higher (Hz) frequency pitch accent than the final element. There is no difference
between SVO and OVS sentences in this respect because the initial element has high pitch accent, whether it is the Subject or the Object. The verb has no pitch accent and it has a flat intonation regardless of the WO of the sentence (SVO, OVS).

O presente estudo tem como objetivo investigar o papel da prosódia no processamento sintático. Nossa hipótese é a de que a prosódia não só impede a ambiguidade, mas também guia o parser, fornecendo pistas para a construção da estrutura sintática no curso do processamento realizado por adultos. Elegemos como objetos de análise as estruturas de Tópico (de argumento interno) e de SVO (não topicalizado) porque, no contraste entre ambas, as pistas prosódicas são acessíveis desde o início da sentença. Um conjunto de experimentos foi realizado com os seguintes objetivos: na produção: (a) verificar as propriedades prosódicas de sentenças com estruturas SVO e de Tópico em tarefas de leitura; (b) investigar se há uma preferência por uma prosódia default; na compreensão: (c) verificar se há preferência por uma ou outra estrutura, a partir da comparação do tempo de processamento de estímulos auditivos com e sem pistas prosódicas; (d) verificar se a modificação dessas pistas poderia "enganar" as escolhas do parser. Para a construção dos estímulos experimentais, foram selecionadas palavras que podem pertencer tanto à categoria Verbo, quanto à categoria Adjetivo. Construímos sentenças com os dois tipos de estruturas sintáticas: Tópico – [A criança SUJA]IPa madrinha mandou ela para o banho; e SVO – [A criança]ϕ [SUJA a madrinha] com a comida do almoço. Os resultados dos experimentos de produção revelam que há pistas acústicas que diferenciam os dois tipos de estrutura. Além disso, sugerem também que há uma preferência, na leitura em voz alta, pela prosódia SVO quando o participante desconhece o sentido completo das sentenças. Quanto aos experimentos de compreensão, também parece haver uma preferência pela estrutura de SVO quando as pistas prosódicas não estão acessíveis para o ouvinte. Por outro lado, quando a prosódia é informativa, os resultados sugerem que esta não só guia o parser na escolha da estrutura sintática, mas também poderia “enganá-lo”, levando ao processamento de uma estrutura diferente nos casos de incongruência entre sintaxe e prosódia. Em conjunto, os resultados revelam que, por um lado, parece haver uma estrutura default SVO, mas, por outro, a prosódia de Tópico parece impedir, em certa medida, a ativação desse default. Com os tipos de estruturas analisadas e com base nos resultados experimentais, defendemos que a prosódia guia essas projeções, já que as pistas acústicas estão acessíveis desde o início das sentenças. De acordo com a proposta de Bocci (2008), as propriedades de Tópico estariam codificadas na sintaxe, guiando a derivação sintática; tais propriedades, por sua vez, seriam disponibilizadas, previamente, via prosódia. Os resultados obtidos são discutidos à luz de três abordagens teóricas: a hipótese do Bootstrapping Prosódico/Fonológico (MORGAN & DEMUTH, 1996; CHRISTOPHE et al., 1997, 2008), que sustenta que pistas prosódicas promovem a segmentação do fluxo de fala, facilitando o processamento (no caso dos adultos); o Modelo Integrado da Computação On-line (CORRÊA & AUGUSTO, 2006; 2007), segundo o qual a árvore sintática vai se formando no curso do processamento; e o Modelo de Compreensão Auditiva da Linguagem (FRIEDERICI, 2011), que prevê a interação da prosódia com a sintaxe no nível neurofisiológico.
This study investigates the role of prosody in syntactic processing. Our hypothesis is that prosody could not only prevent ambiguity, but it also guides the parser, providing cues to the syntactic tree construction during linguistic processing by adults. We elected Topic (of intern argument) and SVO (nontopicalized) structures because in contrast with both of them, the prosodic cues are accessible from the beginning of the sentences in both structures. A set of experiments was conducted according to the following objectives: in production: (a) to verify the prosodic properties of SVO and Topic sentences in reading experiments; (b) to investigate if there is a preference for a default prosody; in comprehension: (c) to verify the preference for each structure by comparing listening reaction time with or without prosodic cues; (d) to verify if the modification of these cues could "trick" the parser choices. For the construction of experimental stimuli, words that may belong to Verb category as well as Adjective category were selected. We built sentences with both types of syntactic tree: Topic – [A criança SUJA]IP a madrinha mandou ela para o banho; and SVO – [A criança]ϕ [SUJA a madrinha] com a comida do almoço. (Topic – The dirty child was sent to have a shower by their godmother; and SVO – The child soils their godmother with the lunch food.) The results of the production experiments revealed that there are acoustic cues which differentiate both types of structure. Furthermore they suggest that there is a preference, when reading it aloud, for SVO prosody production when participants are not aware of the full meaning of the sentences. As regards the comprehension experiments it also showed a preference for SVO structure when prosodic cues are not accessible to the listener. On the other hand, when the prosody is informative, the results suggest that not only it guides the parser in syntactic structure choices, but also it could “trick” and mislead it to the processing of a different structure in the cases of incongruity between syntax and prosody. Altogether the results reveal that, on the one hand, it seems to have a SVO default structure, but, on the other hand, the Topic prosody seems to prevent, in a way, the activation of this default. Having the analyzed structures and based on the experimental results, we indorse that the prosody guides these projections, since the acoustic cues are accessible from the beginning of sentences. According to Bocci’s proposal (2008), Topic properties would be coded in syntax, guiding the syntactic derivation; in turn, these properties would be previously available via prosody. The obtained results are discussed in the light of three theoretical approaches: the Prosodic/Phonological Bootstrapping Hypothesis (MORGAN & DEMUTH, 1996; CHRISTOPHE et al., 1997; 2008), which holds that prosodic cues promote speech stream segmentation, facilitating linguistic processing (in case of adults); the Integrated Model of Online Computation (CORRÊA & AUGUSTO, 2006; 2007), according to which the syntactic tree is created during the course of processing; and the Auditory Comprehension Model of Language (FRIEDERICI, 2011), which foresees the prosody-syntax interaction on the neurophysiological level.

Este trabalho traz o estudo de estruturas que apresentam posposição do sujeito e a influência das mesmas no processo de concordância verbal em gêneros escritos de imprensa do Português Brasileiro (PB), datados entre 2008 e 2010. Para tanto, selecionamos, como corpus desta pesquisa, os gêneros editorial, carta dos leitores, noticiário, coluna e entrevista – seções que apresentam traços mais informais e subjetivos de seus usuários/leitores, dos jornais Folha de São Paulo, Jornal da Tarde, Notícias Já e Diário de São Paulo e das revistas Istoé Gente, Época, Malu Mulher e Aparecida, por estes serem meios de comunicação de imprensa escrita, direcionados a diferentes leitores e com grande circulação nacional. Fizemos um levantamento das ocorrências de sujeitos pospostos nos gêneros escritos de imprensa, analisamos os dados, levantando, ao final, nossas considerações sobre a relação posição do sujeito X concordância verbal. Trazemos a hipótese de que o sujeito posposto na escrita, assim como ocorre na fala, desfavoreça a CV, pois, por não se apresentar em posição de tópico e não condizer com a definição dada pela Gramática Tradicional, “ser de quem se diz alguma coisa”, características estas principais para a identificação do sujeito em uma oração, o usuário da língua tende a identificá-lo como sendo outro termo da oração, havendo ou não um termo que ocupe a posição inicial da oração em seu lugar, não realizando, com isto, a concordância entre o verbo e este SN sujeito pós-verbal

Inom psykologin har det länge varit intressant att studera personligheter för att förklara individers beteenden. Ett välstuderat beteendemönster är om personer är prosociala eller inte. Prosociala är generösa mot andra och icke-prosociala ser till sin egen vinning. Tidigare studier har visat att personlighetsegenskaper som Big Five och socioekonomisk status kan påverka en persons generositet och förmodligen predicera prosocialitet. Syftet med studien var att undersöka vilka personlighetsegenskaper som predicerar att en person är prosocial. Social önskvärdhet kontrolleras för att se om personer som beter sig socialt önskvärt även var prosociala. Social Value Orientation, ett ekonomiskt spel, användes i studien för att mäta om en person var prosocial. Resultatet baserades på 131 undersökningsdeltagares svar på en enkät. En multipel regressionsanalys visade att ingen prediktor förutom socioekonomisk status var relaterad till om en person var prosocial. Dock gick samtliga variabler i förutspådd riktning vilket är värt att lyfta fram.

A database was created for the thermodynamic analysis of phase formation reactions in the SrO – Al₂O₃ – SiO₂ system. The process of solid-phase synthesis of slavsonite was thoroughly investigated and possible ways of the reaction of formation of slavsonite from different intermediate compounds were found. It has been established that due to the formation of intermediate silicon strontium from 400 and 500 °C (Sr₂SiO₄ and SrSiO₃ respectively), the synthesis of slavsonite begins at 1200 °C. In the case of the formation of strontium aluminates Sr₃Al₂O₆ and SrAl₂O₄ (in the case of SiO₂ deficiency), the synthesis of slavsonite occurs after crystallization and subsequent decomposition of Sr-gelite at a temperature of ~ 1600 °C. Within primary slavsonite crystallization in SrO – Al₂O₃ – SiO₂ systems non-stechiometric composition (SrAl₂,₀₃₄Si₃,₁₀₈O₁₀,₂₆₇), that ensures the synthesis of the slavsonite at temperatures up to 1250 °С, were found. The influence of single-component (SnO₂, Cr₂O₃, Li₂O, ZrSiO₄, TiO₂, B₂O₃, MoO₃, CaF₂) and multicomponent eutectic (LiF : NaF, LiF : KF, KF : NaF, LiF : KF : NaF, Li₂O : SnO₂) additives on the intensification of sintering and phase formation processes of slavonite ceramics was studied. The patternes of the formation of microstructure and phase composition of low temperature radio-transparent ceramics in the presence of additives of complex intensifiers which enables the formation of eutectic alloys, and the reduction of the temperature of the formation of the slavonite phase are established. The influence of the Li₂O additive (2% by weight over 100% by weight) on the formation of the non - stoichiometric composition of slavsonite, and Li₂O : SnO₂ eutectic additive (in the amount of 1 mass % over 100 mass %) for the synthesis of the stoichiometric composition of the slavsonite in the temperature interval of 1250 – 1350 °C were proved. On the basis of new data, the formulae and the technological parameters for the production of radio-transparent ceramic materials with certain electrophysical properties (ε = 3.57...5.26, tgδ = 0.0073...0.0122 in the microwave range 26 – 37.5 GHz) and increased resource exploitation which determines their functional reliability were developed. Industrial and laboratory-industrial tests were conducted at the enterprises and practical recommendations for the use of the results were developed. The research results are introduced into the educational process of the department of technology of ceramics, refractories, glass and enamels of NTU "KhPI".

З використанням нових даних розроблено склади та технологічні параметри виготовлення керамічних РПМ з заданими функціональними властивостями (ε = 3,57…5,26, tgδ = 0,0073…0,0122) та підвищеним ресурсом експлуатації. Проведено лабораторні та промислові випробовування на підприємствах та розроблено практичні рекомендації щодо використання результатів.Thesis for the degree of Candidate of Technical Sciences (pre-Ph.D. in Philosophy), specialty 05.17.11 – technology of refractory non-metallic materials. – National Technical University "Kharkiv Polytechnic Institute", Kharkiv, 2018 The thesis is devoted to the development of radio-transparent ceramic materials on the basis of the crystalline phase – slavsonite the synthesis of which is carried out at a reduced temperature. A database was created for the thermodynamic analysis of phase formation reactions in the SrO – Al₂O₃ – SiO₂ system. The process of solid-phase synthesis of slavsonite was thoroughly investigated and possible ways of the reaction of formation of slavsonite from different intermediate compounds were found. It has been established that due to the formation of intermediate silicon strontium from 400 and 500 °C (Sr₂SiO₄ and SrSiO₃ respectively), the synthesis of slavsonite begins at 1200 °C. In the case of the formation of strontium aluminates Sr₃Al₂O₆ and SrAl₂O₄ (in the case of SiO₂ deficiency), the synthesis of slavsonite occurs after crystallization and subsequent decomposition of Sr-gelite at a temperature of ~ 1600 °C. Within primary slavsonite crystallization in SrO – Al₂O₃ – SiO₂ systems non-stechiometric composition (SrAl₂,₀₃₄Si₃,₁₀₈O₁₀,₂₆₇), that ensures the synthesis of the slavsonite at temperatures up to 1250 °С, were found. The influence of single-component (SnO₂, Cr₂O₃, Li₂O, ZrSiO₄, TiO₂, B₂O₃, MoO₃, CaF₂) and multicomponent eutectic (LiF : NaF, LiF : KF, KF : NaF, LiF : KF : NaF, Li₂O : SnO₂) additives on the intensification of sintering and phase formation processes of slavonite ceramics was studied. The patternes of the formation of microstructure and phase composition of low temperature radio-transparent ceramics in the presence of additives of complex intensifiers which enables the formation of eutectic alloys, and the reduction of the temperature of the formation of the slavonite phase are established. The influence of the Li₂O additive (2% by weight over 100% by weight) on the formation of the non - stoichiometric composition of slavsonite, and Li₂O : SnO₂ eutectic additive (in the amount of 1 mass % over 100 mass %) for the synthesis of the stoichiometric composition of the slavsonite in the temperature interval of 1250 – 1350 °C were proved. On the basis of new data, the formulae and the technological parameters for the production of radio-transparent ceramic materials with certain electrophysical properties (ε = 3.57...5.26, tgδ = 0.0073...0.0122 in the microwave range 26 – 37.5 GHz) and increased resource exploitation which determines their functional reliability were developed. Industrial and laboratory-industrial tests were conducted at the enterprises and practical recommendations for the use of the results were developed. The research results are introduced into the educational process of the department of technology of ceramics, refractories, glass and enamels of NTU "KhPI".

Syftet med denna studie är att undersöka vad som händer när ett läromedel i kursen Svenska 1 ändras och anpassas till kursen Svenska som andraspråk 1. I undersökningen har granskats huruvida innehållet i de båda läromedlens kapitel om språksociologi motsvarar intentionerna i det centrala innehållet. Dessutom har de innehållsliga och formmässiga förändringar SVE-boken genomgått för att bli SVA studerats. Genom närläsning av de bägge kapitlen har innehåll och språklig form granskats, och fynden har kategoriserats och analyserats. De viktigaste resultaten är att stoffet i läromedlen motsvarar det centrala innehållet relativt väl, men att det finns en avsevärd skillnad i innehållet mellan de båda bokversionerna. Språket har när SVE blivit SVA vid enstaka tillfällen förenklats, vilket gett innehållsliga skillnader, men har i övrigt inte ändrats i någon väsentlig grad.

A import?ncia do uso de FPGAs como aceleradores vem crescendo fortemente nos ?ltimos anos. Companhias como Amazon e Microsoft est?o incorporando FPGAs em seus data centers, objetivando especialmente acelerar algoritmos em suas ferramentas de busca. No centro dessas aplica??es est?o algoritmos de aprendizado de m?quina, como ? o caso da M?quina de Vetor de Suporte (SVM). Entretanto, para que essas aplica??es obtenham a acelera??o desejada, o uso eficiente dos recursos das FPGAs ? necess?rio. O projeto possui como objetivo a implementa??o paralela em hardware tanto da fase feed-forward de uma M?quina de Vetores de Suporte (SVM) quanto de sua fase de treinamento. A fase feed-forward (infer?ncia) ? implementada utilizando o kernel polinomial e de maneira totalmente paralela, visando obter a m?xima acelera??o poss?vel ao custo de uma maior utiliza??o da ?rea dispon?vel. Al?m disso, a implementa??o proposta para a infer?ncia ? capaz de computar tanto a classifica??o quanto a regress?o utilizando o mesmo hardware. J? o treinamento ? feito utilizando Otimiza??o Sequencial M?nima (SMO), possibilitando a resolu??o da complexa otimiza??o da SVM atrav?s de passos simples. A implementa??o da SMO tamb?m ? feita de modo extremamente paralelo, fazendo uso de t?cnicas para acelera??o como a cache do erro. Ademais, o Kernel Amig?vel ao Hardware (HFK) ? utilizado para diminuir a ?rea utilizada pelo kernel, permitindo que um n?mero maior de kernels seja implementado em um chip de mesmo tamanho, acelerando o treinamento. Ap?s a implementa??o paralela em hardware, a SVM ? validada por simula??o e s?o feitas an?lises associadas ao desempenho temporal da estrutura proposta, assim como an?lises associadas ao uso de ?rea da FPGA.
The importance of Field-Programmable Gate Arrays as compute accelerators has dramatically increased during the last couple of yers. Many companies such as Amazon, IBM and Microsoft included FPGAs in their data centers aiming to accelerate their search engines. In the center of those applications are many machine learning algorithms, such as Support Vector Machines (SVMs). For FPGAs to thrive in this new role, the effective usage of FPGA resources is required. The project?s main goal is the parallel FPGA implementation of both the feed-forward phase of a Support Vector Machine as well as its training phase. The feed-forward phase (inference) is implemented using the polynomial kernel in a highly parallel way in order to obtain maximum throughput at the cost of some extra area. Moreover, the inference implementation is capable of computing both classification and regression using a single hardware. The training phase of the SVM is implemented using Sequential Minimal Optimization (SMO), which enables the resolution of a complex convex optimization problem using simple steps. The SMO implementation is also highly parallel and uses some acceleration techniques, such as the error cache. Moreover, the Hardware Friendly Kernel (HFK) is used in order to reduce the kernel?s area, enabling the increase in the number of kernels per area. After the parallel implementation in hardware, the SVM is validated by simulation. Finally, analysis associated with the temporal performance of the proposed structure, as well as analysis associated with FPGA?s area usage are performed.

Syftet med denna uppsats är att undersöka vilken roll SVA-lärarstudenter tycker att skönlitteraturen bör ha i SVA-undervisningen. Uppsatsen ämnar svara på vilken funktion studenterna tycker att skönlitteraturen fyller i SVA-undervisningen, hur de ser på skönlitteraturens plats i styrdokumenten och även hur SVA-lärarutbildningen har förberett dem för framtida skönlitterär undervisning i SVA. Metoden för studien är kvalitativ intervju, dels genom fokusgruppintervju och dels genom uppföljande individuella intervjuer. Informanterna är sex SVA-lärarstudenter på ämneslärarprogrammet på Uppsala universitet. Resultatet visade att informanterna menar att skönlitteratur kan bidra till språkutveckling, identitetsskapande och omvärldskunskap och därav bör ha en given plats i SVA-undervisningen. Däremot upplever informanterna sig mindre väl förberedda inför att undervisa om skönlitteratur i SVA, då deras egen SVA-lärarutbildningen innehåller för lite skönlitteraturundervisning och för liten praktisk anknytning.

Support Vector Machines (SVMs) are used for a growing number of applications. A fundamental constraint on SVM learning is the management of the training set. This is because the order of computations goes as the square of the size of the training set. Typically, training sets of 1000 (500 positives and 500 negatives, for example) can be managed on a PC without hard-drive thrashing. Training sets of 10,000 however, simply cannot be managed with PC-based resources. For this reason most SVM implementations must contend with some kind of chunking process to train parts of the data at a time (10 chunks of 1000, for example, to learn the 10,000). Sequential and multi-threaded chunking methods provide a way to run the SVM on large datasets while retaining accuracy. The multi-threaded distributed SVM described in this thesis is implemented using Java RMI, and has been developed to run on a network of multi-core/multi-processor computers.

In this work, it is developed a technical economic evaluation about issues related to energy supply to rural areas through distribution networks of low cost implantation and maintenance, in the context of the Brazilian programs intended to assure energy delivery to rural population.The investigation of the subject is based on some relevant aspects of the social economic Brazilian context at present time, where the program to assure energy delivery to rural population is being implemented. Among these aspects, it can be mentioned the great dispersion of consumers in rural areas and the present social situation where more than ten million people still do not have access to electric energy. The conjunction of these aspects indicates the need of searching technical alternatives, because the investment projected to finance the program will be high,in accordance with data published by Brazilian Ministry of Energy.Among these technical alternatives of rural electrification, the limitingaspects and aspects of feasibility of single wire earth return systems of energy distribution are explored. In this perspective, the impact of the present practice of stealing neutral conductor of rural networks is considered, in terms of the aspects related to safety of the people who use electric installations that have lost their interconnection with the potential of the neutral conductor of electrical system. A technical economic comparative study between the single wire earth returnsystem and phase-neutral system is also presented, taking into account the characteristics of energy consumption and demand of rural Brazilian areas and, overall, the consumer units connected from the Brazilian programs intended to assure energy delivery to rural population.Neste trabalho é desenvolvida uma avaliação de natureza técnico-econômica sobre questões relacionadas ao abastecimento de energia em regiões rurais através de redes de distribuição de baixo custo de implantação e manutenção, no contexto dos programas brasileiros de universalização do atendimento de energia. A investigação do tema tem como fundamentação alguns aspectos relevantes do contexto socioeconômico brasileiro atual em que o programa de universalização do atendimento de energia está sendo realizado. Dentre esses aspectos pode-se citar a grande dispersão de consumidores em áreas rurais e o quadro social atual onde mais de dez milhões de pessoas ainda não tem acesso à energia elétrica. A conjunção desses aspectos indica a necessidade de buscar alternativas técnicas quepossam reduzir o custo da universalização do atendimento de energia uma vez que o investimento projetado para custear o Programa Luz para Todos é de sete bilhões de reais, de acordo com dados publicados pelo Ministério de Minas e Energia. Dentre essas técnicas alternativas de eletrificação rural, são explorados os aspectos limitadores e de viabilidade de sistemas monofásicos de distribuição de energia com retorno por terra. Nessa perspectiva, considera-se o impacto da atualprática de furto de condutor neutro das redes rurais, quanto aos aspectos relacionados à segurança de pessoas que utilizam as instalações elétricas que perderam a interligação com o potencial do condutor neutro do sistema elétrico. Um estudo de ordem técnica e econômica comparando o sistema monofilar com retorno por terra e o sistema monofásico fase-neutro também é apresentado levando em consideração as características de consumo e de demanda energéticados consumidores de áreas rurais brasileiras, sobretudo, as unidades consumidoras ligados a partir da universalização do atendimento de energia.

Lightning Location Systems (LLSs) are advanced tools to provide data related to lightning occurrence. They employ remote measurements of electromagnetic field that is irradiated by lightning current to provide relevant information for lightning protection application. As any physical system, the LLSs are submitted to errors in their indications. Such errors may result from the hypothesis assumed on system conception and mainly from the influence of environment factors on the propagation of electromagnetic signal before it is detected at the system remote stations. The manufacturer tries to compensate the system errors by means of corrections and adjustments, which are implemented at LLS from statistical analysis of their indications and redundancy. Nevertheless, eventual systematic errors, such as those ones associated to the influence of relief and soil conductivity, may be not corrected by such compensation. In this work an innovative methodology able to allow an effective calibration of LLS was developed. Its approach is based on the collection of reference data related to actual lightning events to be compared to LLS registers. In order to generate such references, a special electronic device was developed. It is able to register the instant of lightning occurrence and the current waveform, by means of non-direct measurement of the magnetic field associated to the lightning current. Using data from the LLS installed in Minas Gerais State, the geographic distribution of such electronic devices was designed to compose a local network intended to calibrate this system. As a first step, a parcel of the network was installed, placing the devices at sites of recognized high density, in order to collect a significant amount of data in a short period of time.Os Sistemas de Localização de Descargas Atmosféricas (LLS's) consistem numa das ferramentas mais evoluídas para análise de incidência de descargas atmosféricas. Tais sistemas utilizam a medição remota do campo eletromagnético irradiado pela corrente da descarga para determinar a localização do ponto de incidência, o instante de ocorrência e outros dados de grande relevância para aplicações na engenharia de proteção. Como qualquer sistema físico, os LLS's são susceptíveis a erros em suas medições. Estes erros podem resultar de considerações assumidas na concepção do sistema e, principalmente, da influência do meio ambiente local na propagação do sinal eletromagnético, antes do mesmo ser detectado pelas estações remotas do LLS. O fabricante tenta compensar estes erros utilizando correções e ajustes implementados através de análises estatísticas dos dados indicados pelos sensores e redundâncias de informações. No entanto, eventuais erros sistemáticos, como os erros associados ao relevo e à condutividade do solo, podem não ser corrigidos por tais compensações. Neste trabalho foi desenvolvida uma metodologia inovadora capaz de permitir a calibração efetiva do LLS. Esta metodologia se baseia na obtenção de dados de referência correspondentes a eventos de descargas reais para comparação com as indicações do LLS para a mesma ocorrência. Para gerar tais referências, foi necessário a concepção e o desenvolvimento de um dispositivo capaz de registrar o instante da incidência da descarga e a forma da onda de corrente obtida através de medição indireta (a partir do campo magnético associado à corrente). Utilizando-se os dados do LLS instalado em Minas Gerais, foi projetada a disposição geográfica de uma rede destes dispositivos no Estado para fins de calibração do sistema local. Preliminarmente, uma parcela desta rede foi instalada em locais de alta incidência de descargas para possibilitar a coleta de um volume significativo de dados de referência num curto intervalo de tempo.

The modern Lightning Location Systems (LLS) are the most advanced tool to provide lightning data in a wide scale range. Despite the LLS potentiality, the use of LLS data to support the design and operation activities in electric power systems is still relatively poor. In this work an original methodology was developed. It explores the application of LLS data combined to evaluations based on transmission line data to define critical spots along the line in terms of lightning performance. This allows determining the structures (towers or poles) where protection investments are recommended. The methodology is based on the determination of backflashover risk for each transmission line structure. The methodology was applied to real transmission lines and good results were achieved.Os modernos Sistemas de Localização de Descargas Atmosféricas (LLS) constituem-se na mais avançada ferramenta para aquisição de dados de descargas atmosféricas em larga escala.

Neste trabalho foi desenvolvida uma metodologia original, que explora a aplicação do LLS em conjunto com avaliações baseadas em dados de linhas de transmissão para definir os pontos críticos das mesmas quanto ao desempenho frente a descargas atmosféricas e para indicar as torres críticas da linha.

A metodologia foi aplicada a linhas de transmissão reais, apresentando resultados satisfatórios.

Lightning Induced Voltages are known as one of the most important phenomena capable to cause severe damages to electrical systems and telecommunication networks. Despite the lower severity of their effects in relation to those associated with direct strikes, the probability of occurrence of lightning induced voltages is much more pronounced. This scenario justifies the development of evaluations that aim a better characterization of such phenomenon. The objective of this work is to present a computational model for lightning induced voltages calculations based on electromagnetic field equations. Such model incorporates simultaneously the current distribution along lightning channel and the electromagnetic coupling between line conductors and channel. Furthermore, both stages are automatically computed without the requirement of theoretical assumptions of the behaviour of lightning current distribution or of the electromagnetic interaction between the elements of the analyzed system. The model has physical appeal and reproduces, even in a simplified way, physical features and associated process of the lightning channel. In addition, it can also model conductors in any arbitrary angles, allowing evaluations concerning inclined lightning strokes, tortuosities along the channel and complex line configurations. The main aspects concerning the model application to determine the temporal and spatial current distribution along the channel are described, including the adopted considerations to represent physical features of the channel. Sensitivity analyses to evaluate the effect of several parameters in such distribution are presented. Furthermore, comparison of electromagnetic fields calculated by the model and experimental data are performed, remarking a good agreement between them. Systematic simulations concerning the model application for lightning induced voltages calculations were developed in order to evaluate the role played by the most relevant parameters on the resultant induced voltage. It was also performed comparison of results with other traditional models presented in literature for lightning induced voltages evaluations, as well the comparison with experimental data from lightning induced voltages measurements. The obtained results remarked the reliability of the proposed model. This work also presents the approach to take into account the effect of soil resistivity on lightning induced voltages concerning the modification of the electromagnetic coupling between lightning channel and line conductors. The obtained results remarked very similar behaviour in comparison with other evaluations reported in literature.As tensões induzidas por descargas atmosféricas constituem-se em um dos mais importantes fenômenos capazes de causar danos aos sistemas de energia elétrica e às redes de telecomunicação. A despeito da menor severidade de seus efeitos em relação àqueles provenientes da incidência direta da descarga sobre a linha, a probabilidade de ocorrência das tensões induzidas é bastante elevada. Este quadro tem motivado a realização de pesquisas visando uma melhor caracterização desse tipo de fenômeno. Neste contexto se insere este trabalho de doutorado que tem como objetivo apresentar uma modelagem computacional para o cálculo de tensões induzidas por descargas atmosféricas baseada nas equações básicas do eletromagnetismo. Ao contrário da maioria dos modelos empregados na literatura para as avaliações de tensão induzida, esta modelagem é capaz de computar de forma integrada a distribuição de corrente de retorno no canal de descarga e o acoplamento eletromagnético entre os condutores da linha e o canal. Ademais, ambas as etapas são processadas automaticamente, sem a necessidade de estabelecimento de hipóteses quanto ao comportamento da corrente no canal ou da interação eletromagnética linha-canal. Este modelo apresenta uma maior consistência física quando permite reproduzir, ainda que de forma simplificada, características e processos físicos associados ao canal de descarga. Além disto, esta modelagem possibilita a representação de condutores com orientação espacial arbitrária, facilitando o desenvolvimento de avaliações referentes a canais de descarga inclinados, com ramificações e tortuosidades, além de configurações de linha complexas. Os aspectos principais da aplicação da modelagem para determinação da distribuição temporal e espacial da corrente de retorno são descritos. Análises de sensibilidade avaliando a influência de diversos parâmetros em tal distribuição são apresentadas. São realizadas comparações entre resultados de campo eletromagnético gerados pelo modelo e dados de medição, destacando um grau de concordância satisfatório. Simulações sistemáticas referentes à aplicação da modelagem para o cálculo de tensões induzidas deram origem a um conjunto extenso de resultados, propiciando a avaliação da influência dos fatores mais relevantes na determinação do fenômeno. Além da comparação com dados experimentais de medição, também foram desenvolvidas comparações de resultados com outros modelos tradicionais apresentados na literatura para cálculo de tensões induzidas. Os resultados obtidos denotaram a consistência da modelagem aqui aplicada. O trabalho ainda inclui uma abordagem para considerar o efeito da resistividade do solo nas tensões induzidas, por meio da modificação do acoplamento eletromagnético entre os elementos que constituem o canal de descarga e os elementos da linha. Os primeiros resultados obtidos reproduziram comportamentos similares aos gerados por outras avaliações reportadas na literatura.

The perception that distribution system components could be subjected to voltage and current waveforms not specified by currently adopted standards has motivated studies dedicated to investigate the interaction of lightning with distribution networks. In this context, a new return-stroke model was developed. This model, called DNUTL model, represents the lightning channel as a non-uniform transmission line with time-varying parameters. Several analyses were performed aiming at identifying the influence of the spatial and temporal variation of both the channel resistance and capacitance on the return-stroke current, on associated electromagnetic fields and on lightning-induced voltages on overhead lines. The obtained results indicate that the DNUTL model is able to reproduce all features typically observed in lightning electromagnetic fields. With the application of the DNUTL model, it was also possible to confirm that, in certain conditions, simplified return-stroke models can be successfully applied in the calculation of lightning-induced voltages. Aiming at performing evaluations on complex network configurations including the effect of non-linearities, a methodology to calculate lightning-induced voltages in time domain applying the Alternative Transients Program (ATP) was proposed and implemented. This methodology adopts the coupling model of Taylor/Agrawal and allows the use of any return-stroke model to predict the incident electromagnetic field. In addition, models able to represent the behavior of system components when subjected to lightning surges were also implemented in the ATP platform. Some of them, like the transformer and insulator models, were found in the literature. Others, such as the simplified grounding model and the current waveforms dedicated to represent typical features of first and subsequent strokes measured at Morro do Cachimbo Station, were originally proposed in this thesis. With the aid of the implemented models, investigations were carried out in order to provide an estimate of the influence of several parameters on lightning surges developed in a typical distribution system. The obtained results, apart illustrating the effects of direct strikes and lightning-induced voltages on the evaluated system, contributed to characterize the performance of medium voltage surge arresters in terms of associated currents and energies. This allowed a preliminary assessment of the validity of waveforms recommended by currently adopted standards to evaluate the performance of protective devices in laboratory.A percepção de que componentes de sistemas elétricos de distribuição podem ser submetidos a formas de onda de tensão e corrente diferentes das recomendadas por normas para a avaliação de seu desempenho em laboratório motivou a realização de estudos computacionais dedicados a investigar os principais mecanismos de interação entre as descargas atmosféricas e as redes de distribuição. Neste contexto, foi desenvolvido um novo modelo de corrente de retorno, chamado DNUTL, que representa o canal de descarga como uma linha de transmissão não uniforme com parâmetros variáveis no tempo. A partir do modelo implementado, foram realizadas análises que buscaram identificar a influência da variação temporal e espacial da resistência e da capacitância do canal na propagação da corrente de retorno, nos campos eletromagnéticos associados e também em tensões induzidas em linhas aéreas. Os resultados obtidos indicam que o modelo DNUTL é capaz de reproduzir todas as características normalmente observadas em campos eletromagnéticos gerados por descargas atmosféricas. Através do modelo proposto, também foi possível confirmar a viabilidade de utilização de modelos de corrente de retorno simplificados em determinados estudos de tensões induzidas por descargas atmosféricas. Com o objetivo de avaliar redes de distribuição com configurações complexas, incluindo não-linearidades, foi proposta e implementada uma metodologia para o cálculo de tensões induzidas no domínio do tempo empregando a plataforma ATP. Esta metodologia adota o modelo de acoplamento de Taylor/Agrawal e permite a utilização de qualquer modelo de corrente de retorno na predição do campo eletromagnético incidente. Também foram implementados no ATP modelos capazes de representar o desempenho de diversos componentes de redes de distribuição quando submetidos a solicitações com características impulsivas. Alguns deles, como os modelos de transformadores e isoladores, se basearam em trabalhos já disponíveis na literatura. Outros, como o modelo simplificado de aterramentos e as formas de onda de corrente representativas de primeiras descargas de retorno e de descargas subseqüentes medidas na Estação do Morro do Cachimbo, foram originalmente propostos nesta tese. De posse dos modelos implementados, foram realizados estudos com a finalidade de estimar a influência de diversos parâmetros em tensões e correntes resultantes em um sistema de distribuição típico. Os resultados obtidos, além de ilustrar os efeitos de descargas diretas e indiretas no sistema avaliado, contribuíram para com uma caracterização do desempenho de pára-raios de média tensão em termos das correntes e energias associadas. Isto permitiu uma análise preliminar a respeito da representatividade de formas de onda de corrente recomendadas por normas para o ensaio destes dispositivos.

It was checked the inner quality of 1152 consumption eggs from three large egg distributors in the state of Minas Gerais. The treatments were arranged in randomized blocks, being repetitions the block, in factorial 3x2x4, with three distributors of eggs, two storage temperatures (ambient and refrigerated) and four storage periods (zero, seven, 14 and 21 days). The parameters of egg quality analysed were Haugh Unit (HU), albumen pH (pH) and for microbiological were analysed total count of mesophilic aerobic (CFU/g), total and thermal coliforms (CFU/g), Salmonella spp., Staphylococcus spp. and yeasts and molds (CFU/g). It was observed decrease of internal quality of eggs with the period of storage. The pH values increased with the period of storage of eggs for all distributors regardless the temperature of storage and, HU values decreased with storage, however it sharply decrease in eggs kept at room temperature for all distributors. The microbiological analyses showed the absence of Salmonella spp. and coagulase positive Staphylococci. However, it was observed the presence of coagulase negative Staphylococci, and also yeasts and molds, besides mesophilic aerobic, total coliforms and thermal which presented some results above the legal standards. It was concluded that the quality of eggs of the three distributors of Minas Gerais had the same standard of internal quality.Verificou-se a qualidade interna de 1152 ovos de consumo provenientes de três grandes distribuidoras de ovos do estado de Minas Gerais. Os tratamentos foram dispostos no delineamento em blocos ao acaso, sendo as repetições o bloco, em arranjo fatorial 3x2x4, com três distribuidoras de ovos, duas condições de armazenamento (ambiente e refrigerado) e quatro períodos de estocagem (zero, sete, 14 e 21 dias). Os parâmetros de qualidade dos ovos avaliados foram as Unidades Haugh (UH), o pH do albúmen (pH) e as análises microbiológicas de contagem global de mesófilos aeróbios (UFC/g), coliformes totais e termotolerantes (UFC/g), pesquisa de Salmonella spp., Staphylococcus spp. e bolores e leveduras (UFC/g). Foi observada diminuição da qualidade interna dos ovos durante o armazenamento. O pH aumentou para todas as distribuidoras no decorrer do armazenamento independentemente da temperatura de estocagem e os valores de UH diminuíram com a estocagem porém, houve uma diminuição mais acentuada nos ovos que permaneceram em temperatura ambiente para todas as distribuidoras. As análises microbiológicas indicaram ausência de Salmonella spp. e Staphylococcus coagulase positivo. Entretanto, foi observada a presença de Staphylococcus coagulase negativo e bolores e leveduras, além de mesófilos aeróbios, coliformes totais e termotolerantes que apresentaram alguns resultados acima dos padrões legais vigentes. Foi concluído que os ovos das três distribuidoras de Minas Gerais possuem o mesmo padrão de qualidade interna.

Visuomenė, internetas ir jame esanti informacija dabar turi vieną didžiausių įtakų mūsų asmeniniame gyvenime. Be interneto daugelis dabar, net nebeįsivaizduotų savo kasdienybės, nes jis mums ir padeda atlikti daugelį darbų. Tačiau vis augant duomenų kiekiams internete, informacijos paieška tampa vienu svarbiausių internete naudojamų funkcijų.Paieškos sistemos – tai sistemos, ieškančios dokumentų žiniatinklyje, naujienų grupių archyvuose, FTP saugyklose, kuriuos rado paieškos serveris ir įtraukė į savo duomenų bazes. Ieškant informacijos, vartotojai naudojasi šiomis sistemomis, todėl internetinių svetainių kūrėjai yra suinteresuoti, kad jų internetiniai puslapiai būti kuo dažniau randami paieškos sistemų. Todėl besiplečiant paieškos sistemoms išsiplėtojo SEO (Search Engine Optimization, lietuviškai „Optimizavimas paieškos sistemoms“).Expansion of the Internet and the information contained therein formed such an organization which aims to help the internet users to quickly and efficiently find what he needs. One of them is the Google search engine. It is one of the largest search engine companies in the world. In this paper we will analyse the Google search engine, and its proposed content optimization methods, which it claims to helps achieve better search results positions. The paper will discuss techniques such as HTML meta tags, content headers, site maps, robots.txt file, canonical and Paging functions. These methods will be compared with each other, and we will decide which method is most useful for site optimization.

Utgångspunkten har varit att gruppindelning av elever med ett andraspråk är svårt och att det finns olika inriktningar eller diskurser (Hedman & Magnusson, 2018) inom forskningsfältet svenska som andraspråk som har olika lösningar på hur ämnet skall organiseras. En annan utgångspunkt för undersökningen är att språksyn är avgörande för hur sva-elevers språk bedöms och tidigare forskning har bl.a. visat att andraspråkselever förfördelas i ett skolsystem där inlärarspråk bedöms utifrån standardsvenska normer.En arrangerad bedömning har genomförts där två lärare i sve1 bedömt sex redan bedömda texter, skrivna av elever i sva1.

Ingen text får högre betyg än E och två texter underkänns, en av dessa med betyget A i sva1. Texterna får också högre betyg på delaspekten stil än på delaspekten språk. Lärarna är samstämmiga i sina bedömningar och reagerar på samma feltyper i sva-elevernas texter. Avvikelser som noteras av lärarna och som påverkar bedömningen negativt är framförallt formfel, ordföljdsfel och brister i ordförråd.

Thesis (M.S.V.S.)--Massachusetts Institute of Technology, Dept. of Architecture, 1997.Includes bibliographical references.
During August of 1996, I stayed in a series of SRO hotels in New York City leaving a book and diary behind when I checked out of each room. The books that were left in the rooms differ from one room to the other but all contain events and/or situations that could have happened in the very room. Diary entries were left behind between the pages of the books, like bookmarks, to indicate the appropriated passages and to impose my story onto the book's story. SRO, single room occupancy, refers either to an entire hotel or to a room within such a hotel. SRO's are the most inexpensive type of hotel. For social workers the term "SRO" has come to mean a single room occupant - not the bUilding but the person. These cheap single room hotels have been an element of American urban life for nearly two hundred years Nevertheless, they have been the target of an offiCial war within city development, neighborhood gentrification, initiated by people whose concept of "home" does not include the SRO with its accommodations of single rooms or suites, usually without kitchens and often with shared bathrooms. Few, if any, housing alternatives for these reSidents exist. When owners close a building, tenants are lucky if they can find a worse hotel at a higher rate. Myths circulates about today's hotel residents: all are supposedly all friendless, isolated, needy and disabled; all are presumably socially marginal; all are mildly psychotic; all are transients who never live anywhere for more than few months. I knew these myths were not entirely true. After all. I had lived in those hotels for quit a while before I start doing this project.

Cieľom systému Excalibur je presunúť autentifikáciu od hesiel používaných v súčastnosti ku bezheslovej budúcnosti. Zámerom tejto práce je integrácia systému Excalibur s webovými bezheslovými protokolmi SAML a FIDO2. Štandard SAML bol integrovaný do systému Excalibur a úspešne otestovaný s niekoľkými známymi aplikáciami. Excalibur má na starosti samotnú autentifikáciu a manažment používateľov a SAML je použitý na predanie týchto informácii aplikáciam tretích strán. FIDO2 je, na druhú stranu, kompletný autentifikačný štandard, ktorý môže byť do systému Excalibur integrovaný viacerými spôsobmi. Ako najsľubnejší spôsob sa javí výmena autentifikačného mechanizmu systému Excalibur za FIDO2, ale slabá podpora štandardu a chýbajúce funkcie to zatiaľ nedovoľujú.

The topic of this thesis is search engine optimization (SEO). This term covers many activities, procedures and techniques. When using SEO you can improve your position in a search engine and narrow it to so called key words. The first part of the theoretical part acquaints readers with the basic facts, statistics and defines the basic terminology. The main objective of the second part is concentrated on the main elements which affect the successes of optimalization. The practical part is dealing with analysis of the optimalized e-shop including its competitors. The changes and recommendations of improvement and development of the e-shop were suggested on the basis of the analysis, the theoretical acquirements and the experience of the author. These changes are gradually implemented in the following part of the thesis. The impact on the attendance and placement in the search engines is reviewed after the realization of the suggested above.

The Master Thesis deals with offshoring and its logistic requirements. The first part of thesis characterizes terms as outsourcing, offshoring and offshore outsourcing. The main reasons for foreign production are seeking of resources (typically low cost labour) and expansion into new markets. Benefits and risks of offshoring are analyzed in the thesis, as well as criteria for selection of suitable host destination. Often overlooked impacts of globalization on integrated supply chain are also considered in this thesis. Central and Eastern Europe is one of important offshoring regions. CEE offers relatively cheap and qualified labour. However, its main benefit is its small geographical distance from Western Europe. The costs of servicing markets at Western Europe from CEE are much lower compared to servicing these markets from Asia.

Les machines à vecteurs support (SVM) sont des modèles de l'apprentissage automatique qui font actuellement l'objet de nombreux travaux de recherche, ceci pour deux raisons principales : d'une part, leurs performances constituent l'état de l'art dans de multiples domaines
de la reconnaissance des formes, d'autre part, elles possèdent des propriétés statistiques remarquables. Le premier modèle de SVM proposé par Vapnik et ses co-auteurs calcule des dichotomies. Il peut être utilisé pour effectuer des tâches de discrimination à catégories multiples, dans le cadre de l'application de méthodes de décomposition. Des SVM multi-classes ont également été proposées dans la littérature, parmi lesquelles nous distinguons celles qui s'appuient sur un modèle affine multivarié, que nous nommons M-SVM. Ce mémoire se présente comme une étude synthétique de la discrimination à catégories multiples au moyen de SVM. Il se concentre plus particulièrement sur l'analyse des M-SVM.
Le chapitre deux est consacré à la description des SVM multi-classes,
à leur mise en oeuvre et à l'analyse de leurs performances. Nous présentons successivement le cadre théorique de leur étude, les différents modèles, une étude théorique de leurs performances en généralisation, leur programmation ainsi que les différentes méthodes de sélection de modèle qui leur sont dédiées. Le chapitre trois décrit une application de la M-SVM de Weston et Watkins en biologie structurale prédictive. Le problème traité est la prédiction de la structure secondaire des protéines globulaires.

We hypothesise that certain market conditions could lead to liquidity shocks that will consequently increase SEO underpricing (defined as the close-to-offer return). We propose three scenarios of market conditions, namely aggregate issues with large volume, large market declines and market volatility. Using a sample of about 5,000 seasoned equity offerings from 1987 to 2009, we found that market volatility is significantly and positively related to SEO underpricing after controlling for other factors. We employed an estimation method proposed by Chambers and Dimson (2009) to examine the behaviour of SEO underpricing over our sample period from 1987 to 2009. We found that after controlling for changing risk composition, price practice, market conditions and the influence of underwriter reputation and analyst coverage, there was still an upward shift in SEO underpricing over the sample period, and the pattern cannot be fully explained by the practice of setting offer prices at lower integers. We borrowed the investment banking power hypothesis from the literature and argued that the upward shift of SEO underpricing over the sample period could be explained by the increase of investment banking power. As the industry structure of underwriting transfers from a competitive market to an oligopoly market, banks use non-price dimensions to gain market power and consequently increase SEO underpricing.

Introduction was dedicated to review the human relationship phenomenon from the philosophical (S.Kierkegaard, M.Heidegger, M.Buber, P.Tilich) and psychological (G.W.Allport, C.R.Rogers, S.M.Jourard, J.Bugental, V.Frankl, A.R.Beisser) perspective. The aim of this work was to explore in what way the phenomenon of uniqueness is experienced in a certain psychotherapy group and define the phenomenon of uniqueness for the certain research group. The method of focus group was used in this research. Focus groups were organized in the context of short-term psychotherapy groups. 13 persons were participating in the focus groups: 11 women and 2 men. 2 focus groups were created, which were managed by the author of this study based on provided plan. The results were processed using A.Giorgi phenomenal method. 10 specific situational definitions of the phenomenon of uniqueness were created, which were used to formulate two ultimate definitions of the phenomenon. Results of the study revealed, that: 1) the phenomenon of uniqueness in a psychotherapy group is complex phenomenon, characterised by large diversity of manifestations; 2) the phenomenon of uniqueness in a psychotherapy group is closely related to universality experience: the uniqueness is experienced together with the universality of the group‘s participants or immediately after it...
