Full textThis dissertation studies the behavior of the errors at the output of the decoder on a satellite communication system. Two different types of channel coding are considered. On one hand, a classical concatenation of a Reed-Solomon with a convolutional code and interleaving. On the other hand, a code from the turbo-codes family. The algorithm used in the convolutional decoding of the first coding system is the maximum likelihood algorithm. It is known that errors at the output of this algorithm are grouped in bursts due to the memory of the code. The group of correct bits between bursts is called a gap. Thus, the output of a maximum likelihood decoder can be modeled by a Markov chain with two states: a first state where no errors take place (good state) and a second state where errors appear in bursts (bad state). Regarding the burst modeling, the previous proposed models did not fit the simulation results for low and average burst lengths. Therefore, we have developed a new model based on the properties of the code that fits the range of all possible bursts lengths. On the second coding system, instead of using a maximum likelihood decoding, iterative decoding based on the successive decoding of each constituent code is considered. These iterative decoding algorithms are based on the Maximum A Posteriori (MAP) principle. This dissertation analyses the behavior of the errors at the output of such iterative decoders and proposes a model that fits quite well with the real errors simulated via Monte Carlo simulations

Full textActuality of theme. One of the ways to develop electricity networks in Ukraine is to connect new household and industrial consumers, namely the reconstruction of existing lines to meet the level of electricity quality. The main problems are: - non-transparency of electricity connection services installations to electric networks; (The main problem with joining is that, you never have exactly anyone will tell at once - how much will cost connection to an electric network with a certain point on the map and how long it will take. This phenomenon creates opportunities to "bid" with customers to "squeeze" out of them maximum economic benefit ". That is why many foreigners investors transfers their production to other countries). - non-transparent procedure for determining the fee for connection to the electricity grid; (The accession fee should be non - discriminatory and transparent, and also be published in the public domain. - with such conditions everyone will be able to calculate the price with an accuracy of 90-95%, but remains issues of transparency. Now the customer can set requirements which equal to, or exceed the cost of a conventional connection) - inconsistency of Ukrainian legislation with EU legislation; (After the President of Ukraine signed the law on the electricity market, a two-year transition began, during which the entire market architecture will be rebuilt in accordance with the rules in force in the EU. Competition should appear in the industry and cross-subsidization should disappear) Yes, there are many other issues that will be considered in this paper, so I think that the topic is quite relevant. Based on the results of the analysis of the technical condition of the energy industry of Ukraine, we establish its unsatisfactory technical condition and organization exploitation, which affects the further development of the country's economy and living standards of the population. In accordance with Ukraine's international obligations should ensure business development (including raising its Doing rating) Business), because today the level of Ukraine does not satisfy the interests society. To ensure the proper level of Ukraine in principle the question is to simplify the procedure and find the optimal connection to electrical networks. The purpose and objectives of research. It consists in reviewing and resolving issues related to improving the efficiency of networks of electricity transmission organizations in terms of connecting consumers to electricity networks through organizational and managerial, technical and economic, regulatory, environmental and technological issues. The object of research - the processes of organization of connection of consumers to the electrical networks of the power transmission organization. The subject of research - methods to increase the efficiency of the organization of accession. Research methods. The methodological basis of the conducted research was the following methods: fuzzy logic (queuing theory), cluster analysis of transformer substation data, mathematical and physical calculations. The scientific and practical value of the work lies in the study of organizational and managerial, technical and economic, regulatory, environmental and technological issues, the formation of proposals to improve the efficiency of the transmission organization to connect consumers to electricity networks, as well as the development of proposals for geographic information management system development and operation of energy facilities in Ukraine.

En applikation för molekylär dynamik drar ofta fördel av stora multiprocessorsystem genom att dela ner simuleringsscenariot i mindre domäner. The nerdelade domänerna fördelas på instanser som körs parallellt. Ett problem som kan uppstå vid nerdelning av domän är ojämn last på grund av partikelfördelning i simuleringsscenariot. Denna rapport föreslår ett sätt att lösa detta genom ytterligare nerdelning och distribution av tungt lastade domäner.

Full textIntroduction: The field hospital has been undergoing constant organizational changes due to the introduction of new technologies that encourage patient safety. Those applied to the distribution of drugs can shorten the number of errors distribution, obtain real-time a high level of information about every process and better manage the time of the pharmacist in order to increase the intervention of the prevention of medication errors. A previous study found problems in the repackaging and an average of about 14% of medication errors in Distribution System for Prescription Drugs traveler at a university hospital. Objectives: To evaluate the impact of deployment of new technologies to the largest patient safety in a system of distribution of drugs in a university hospital. The evaluation was divided into: 1) individualization of medication by repackaging, using bar code identification of drugs, 2) identification of critical points in the new process established for the Distribution System for Prescription Drugs traveler, 3) identification and analysis of medication errors after implementation of control system by bar code. Methods: We performed cross-sectional studies. For the evaluation of the individualization process has been developed an assessment tool adapted from recommendations and previous studies, according to the practice of repackaging. We used the assessment tool in routine writing and, through the technique of participant observation, it was found the suitability of its execution, as the same instrument. For the identification of critical points of the Distribution System of Medicines was analyzed and verified every step which could occur from medication errors. For evaluation of the Distribution of Prescription Drugs Individualized was a transversal study, which used the technique of participant observation and convenience sampling. Were evaluated prescriptions linked to the Distribution System for Prescription Drug Individualized technology bar code. Results: To evaluate the process of individualization were observed fractionation of 42 oral dosage forms and injectables where routine writing process of individuation attended 66% of the items recommended and play the same 63% attended. For evaluation of the Distribution of Prescription Drugs Individualized analyzed 290 prescriptions linked to the Distribution System for Prescription Drug Individualized of these, 25% had some type of medication error. The total number of items analyzed was 2659, with 74 occurrences of medication errors (2.78%). Compared with earlier data the number of errors per clinic or in general had a statistically significant reduction. Conclusions: The results show that the use of new technologies increases the quality of service by preventing medication errors. Therefore, the system of reading bar codes associated with changes in the infrastructure and work processes can be described as the major factors in reducing the rates of errors in dispensing drugs in the hospital.

Full textAlthough PCM/TDM framed data is one of the most prevalent formats handled by flight test ranges, it is often required to acquire and process other types. Examples of such non-standard data types are radar position information and meteorological data from both ground based and radiosonde systems. To facilitate the process and management of such non-standard data types, a micro-processor based system was developed to acquire and transform them into a standard PCM/TDM data frame. This obviated the expense of developing additional special software and hardware to handle such non-standard data types.

Resumo: Dentre diversos fatores que determinam o sucesso da osseointegração e da reabilitação protética, a biomecânica se destaca como fator fundamental. Utilizando a técnica da fotoelasticidade, o objetivo neste estudo foi avaliar as tensões geradas ao redor de implantes cone morse e hexágono externo osseointegrados após carregamento distal em diferentes técnicas de carga imediata: barra distal, fundição e solda a Laser. Três infraestruturas similares (uma para cada técnica) foram confeccionadas, sobre uma matriz metálica simulando um arco mandibular edêntulo. Cinco implantes foram dispostos de maneira a simular a distribuição clínica para protocolo inferior convencional. Análogos de mini pilares foram fixados na matriz metálica e após procedimento de transferência e obtenção de modelo em gesso especial, foram confeccionadas as infraestruturas protéticas. Estas foram utilizadas em novo procedimento de transferência e posteriormente, instaladas em modelo fotoelástico confeccionado com resina epóxi flexível (GIV, Polipox Indústria e Comércio Ltda - São Paulo - SP - Brasil). Foi realizado um carregamento pontual de 4,9N na região de primeiro molar inferior direito e, posteriormente primeiro molar inferior esquerdo. Foram avaliados cinco pontos pré-determinados ao longo do implante e as imagens foram analisadas no programa Fringes® de maneira qualitativa e quantitativa através da verificação das ordens de franjas ao redor dos implantes osseointegrados. A média dos valores foi submetida à análise de variância para dados com dois fatores de estudo, seguidos pelo teste de Tukey para comparação entre as médias. Os resultados não apresentaram diferença significativa entre as infraestruturas, porém apresentou diferença significativa entre os tipos de conexões. A partir dos resultados obtidos conclui-se que não há diferença na distribuição de tensão entre as técnicas de obtenção de infraestruturas, porém quando observados os tipos de conexão, o implante Cone Morse apresentou melhores resultados em relação à distribuição de tensão
Abstract: The objective of this study was to evaluate the stresses generated around morse taper and external hexagon osseointegrated implants after distal loading in different immediate loading techniques: distal bar, casting and laser welding. Three similar infrastructures (one for each technique) were fabricated on a metal matrix simulating an edentulous mandible arch. Five implants were arranged to simulate the clinical distribution of conventional lower protocol. Analogs of the implants were fixed in a metal matrix and a transfer procedure was made. After obtaining a special plaster model, the prosthetic infrastructures were fabricated. These were used on a new transfer procedure and subsequently installed in a photoelastic model made with flexible epoxy resin (GIV Polipox Industry and Commerce Ltd - São Paulo - SP - Brazil). A load application of 4.9N was performed at the region of lower right first molar and subsequently lower left first molar. Five predetermined points along the implant were evaluated and the images were analyzed in Fringes ® program in qualitative and quantitative way by checking the orders of the fringes around the dental implants. The mean values were statistically analyzed using a 2-Way analysis of variance and Tukey test. The results showed no significant difference between the infrastructure obtaining techniques, but significant difference was seen between the types of connection. From the results obtained it is concluded that the Morse taper implant showed better results in terms of stress distribution

Full textA contínua evolução da tecnologia de comunicações ópticas observada nos últimos anos vem possibilitando atender a crescente demanda dos usuários por maior largura de banda. Esta nova demanda é atribuída principalmente à popularidade crescente de aplicações de banda larga, tais como TV por protocolo de Internet (IPTV), televisão de alta definição (HDTV), ensino online, e-saúde, filmes digitais de super alta definição (SHD) e e-cultura baseado em vídeo 3-D full-HD. Esta vasta gama de aplicações acabará por necessitar de tipos de serviços diferenciados e taxas de transmissão de dados diversificadas. Como resultado, capacidades de suportar diferenciamento de qualidade de serviço (QoS) e transmissão de múltiplas taxas estão se tornando um desafio para as redes ópticas futuras. Dentre muitas técnicas de multiplexação existentes, OCDMA constitui-se em um candidato potencial para as redes ópticas de próxima geração, particularmente devido a características como operação assíncrona, controle de rede simplificada, fácil adição de novos usuários, e também possibilidade de QoS diferenciado na camada física. O desempenho desta técnica de acesso múltiplo é limitado principalmente por interferência múltipla de acesso (MAI). Embora em sistemas OCDMA de múltiplas taxas e multiserviços a MAI deva ser considerada binomialmente distribuída, outras distribuições de probabilidade para a análise da MAI e, consequentemente, da BER têm sido utilizadas como uma aproximação. Neste contexto, este trabalho propõe um novo formalismo para avaliar o desempenho da BER de sistemas OCDMA 1-D e 2-D de múltiplas taxas e multisserviços considerando a MAI como binomialmente distribuída, o que resulta em uma expressão mais precisa para a BER. Além disso, o método proposto neste trabalho não requer conhecimento, a priori, das sequências de códigos geradas, o que significa que a análise do desempenho do sistema é obtida mais facilmente utilizando apenas os parâmetros do código. Um sistema OCDMA de múltiplas taxas empregando códigos 1-D OOC e 2-D OFFH será também investigado. Uma comparação do desempenho em termos de BER para o sistema baseado em OOC supondo tanto a distribuição de Poisson quanto a binomial para a MAI é investigada. De forma análoga, uma comparação para o sistema de múltiplas taxas baseado em OFFH supondo desta vez tanto a distribuição gaussiana quanto a binomial para a MAI também é analisada. É mostrado que a BER em cenários de múltiplas taxas pode ser superestimada ou subestimada em várias ordens de grandeza, dependendo da distribuição suposta para a MAI e do número de usuários simultâneos no sistema. Além disso, é apresentado pela primeira vez um switch óptico híbrido de pacotes OCDM/WDM capaz de prover transmissões de múltiplas taxas e serviços diferenciados. A arquitetura do switch proposto e seu desempenho em termos de probabilidade de perda de pacotes também são apresentados. Finalmente, é mostrado que o uso da distribuição gaussiana ou poissoniana para a MAI pode não ser apropriado para uma estimativa confiável de BER, uma vez que não são aproximações aceitáveis para avaliar o desempenho de sistemas de múltiplas taxas e multiserviços com boa precisão.

The thesis is to establish the general model of a CDMA system, includes all the influenced factors:fading,shadowing,near-far effect,non-uniform user distribution,sectorization,and voice active factors,etc.This model is used to drive the non-unifom user distribution and the expressions of the outage probability of a CDMA system for the reverse link.The system performance are evaluated for each influenced factor and scheme.According to simulation results,we know that(1)the capacity is serverly influenced by space factor;(2)the worse the terrain is,the fewer users will be;(3)the capacity is increased as the distance becomes longer;(4)our suggestion of the non-uniform user distibution will significantly increase the system capcaity;(5) when we consider that the user distribution model is non- uniform,not only does it influence thesystem capaciyt but also the varity of the parameters.

This thesis is to investigate the multiple functions switching strategy for the 22.8kV underground distribution system within the Taichung distribution automation system (DAS) in Tai-power network. It covers 3 substations, 6 main transformers, 20 feeders and 78 four-way switches. Firstly, when the distribution system in normal status or in abnormal status, by using the coordinates code to reduce the distribution system losses, minimum the feeders of the distribution system unbalanced rate and emergency load transfer to minimum the outage areas to derive the optimal solution of switching operation for the single object function, individually. Secondly, a multiple function of minimums loss and minimum load unbalanced rate of distribution system with the coordinates code method to investigate the optimal compromise solution. In this thesis, it applies the multiple objectives programming to solve the multiple function switching operation of the distribution systems. The effectiveness of the proposal method to derive the compromise switching operation strategy for distribution feeders can provide very important tool for distribution system operation to achieve loss minimization and load balanced.

Full textPower-line communications can be used for the transfer of data across electrical net- works in applications such as automatic meter reading in smart grid technology. As the power-line channel is harsh and plagued with non-Gaussian noise, robust forward error correction schemes are required. This research is a comparative study where a Luby transform code is concatenated with power-line communication systems provided by an up-to-date standard published by electricit e R eseau Distribution France named G3 PLC. Both decoding using Gaussian elimination and belief propagation are imple- mented to investigate and characterise their behaviour through computer simulations in MATLAB. Results show that a bit error rate performance improvement is achiev- able under non worst-case channel conditions using a Gaussian elimination decoder. An adaptive system is thus recommended which decodes using Gaussian elimination and which has the appropriate data rate. The added complexity can be well tolerated especially on the receiver side in automatic meter reading systems due to the network structure being built around a centralised agent which possesses more resources.
