Given the exponential growth in the spread of the virus world wide web (Internet) and its increasing complexity, it is necessary to adopt more complex systems for the extraction of malware finger-prints (malware fingerprints - malicious software; is the name given to extracting unique information leading to identification of the virus, equivalent to humans, the fingerprint). The architecture and protocol proposed here aim to achieve more efficient fingerprints, using techniques that make a single fingerprint enough to compromise an entire group of viruses. This efficiency is given by the use of a hybrid approach of extracting fingerprints, taking into account the analysis of the code and the behavior of the sample, so called viruses. The main targets of this proposed system are Polymorphics and Metamorphics Malwares, given the difficulty in creating fingerprints that identify an entire family from these viruses. This difficulty is created by the use of techniques that have as their main objective compromise analysis by experts. The parameters chosen for the behavioral analysis are: File System; Records Windows; RAM Dump and API calls. As for the analysis of the code, the objective is to create, in binary virus, divisions in blocks, where it is possible to extract hashes. This technique considers the instruction there and its neighborhood, characterized as being accurate. In short, with this information is intended to predict and draw a profile of action of the virus and then create a fingerprint based on the degree of kinship between them (threshold), whose goal is to increase the ability to detect viruses that do not make part of the same family

T he people’s daily lives are surrounded by computing devices, with increasing resources (sensors) and, with increasing processing. How these devices communicate is still not natural and This retards the growth of Ubiquitous Computing. This paper presents a way in which these devices can communicate using Jini technology and concepts of Service Oriented Architecture, applying these concepts in a test case of Ubiquitous Computing. To conduct the test case was constructed a fictitious system for management of a soccer championship, where users can interact with each other and with the system in a simplified way, have access to data in real time of the championship during the event. This communication is performed by services built using Jini technology, which were based on key SOA concepts, such as modularity and reusability

Um dos maiores problemas relacionados ao quotidiano das médias e grandes cidades é o trânsito e por meio dele percebemos os conflitos de circulação urbana e se os meios de transportes fluem de forma satisfatória. Segundo Vasconcellos (1999), transporte público é um conjunto de elementos fÃsicos que se distribui espacialmente, atendendo a população que dele depende. Localizada no oeste do Estado de São Paulo a cidade de Presidente Prudente enfrenta, hoje, um grave problema no tocante à circulação e à eficiência dos meios de transportes públicos, sendo esse oneroso para a população que o usufrui. Em termos proporcionais a tarifa por quilômetro rodado é muito elevada, em comparação à s grandes cidades do Estado de São Paulo e do Brasil. Sendo o transporte público parte essencial de uma cidade, o seu funcionamento deve estar de acordo com o crescimento da mesma e atender qualitativamente e quantitativamente seus usuários, propondo um adequado uso do espaço urbano. Diante de tal realidade, o projeto tem, por objetivo, fomentar a proposta de implantação de terminal urbano de transporte público, baseado no redesenho viário da principal centralidade da cidade...

No inÃcio do trabalho, quando comecei a desenvolver a idéia de estudar a sonoridade musical e misturá-la com a Arquitetura, eu pensava mais em utilizar as caracterÃsticas fluidas do som, essa facilidade que ele tem de se movimentar livremente no ar e, por isso, se dispersar por entre as pessoas muito facilmente, chegando até elas a todo o momento, sem que nenhum empecilho fÃsico o impeça de atingi-las. Então, sabendo da alta sensibilidade que os humanos têm ao som, devido à sua própria natureza estrutural vibratória, eu partiria para uma análise mais particular de como a Música poderia influenciar as pessoas em seu dia-a-dia, de como as pessoas reagem a certos sons. E então utilizar isso dentro da Arquitetura, seja na sua composição, seja na interação e vivência usuário-espaço. Porém, com o andamento dos estudos e com o desenvolvimento do projeto, ocorreu que não poderia deixar certos aspectos de lado, como por exemplo, estudar técnicas que usamos para compor ambas as Artes, como as estruturações utilizadas, elementos rÃtmicos, harmônicos, proporcionais, estudar o próprio som e a matéria, fundamentais na Música e na Arquitetura, assim como a questão da temporalidade e da espacialidade. Ainda assim, não via o trabalho como completo. Por isso optei por acrescentar mais uma parte a ele, complementar a todo o desenvolvimento já elaborado e à s questões já estudadas, porém de fundamental importância para a conclusão do projeto. Será o capÃtulo intitulado Musicalidade Aplicada, o qual ainda é subdividido em Música & Arquitetura, onde apresento alguns projetos exemplares, nos quais os autores de alguma forma se utilizaram de música na composição e/ou execução de suas obras; e Música & Urbanidade, onde finalmente apresento a sonoridade musical como um meio de mudança da perspectiva humana, mudança de posicionamento e olhar do homem para o próprio homem e do meu olhar para a arquitetura

Usually organic polymeric diodes are made with a semiconductor layer placed between two electrodes in a sandwich-like architecture, where the electrodes are deposited on the surfaces of a polymeric semiconductor film. This methodology leads to two main problems: i) the polymeric film top surface is rough and irregular, resulting in non-uniform electric field into the device; ii) during the deposition of metallic electrode in the top surface polymeric film, by thermal evaporation, occurs the diffusion of metal atoms into the polymeric film, changing the material electronic structure. Thus, the metal-semiconductor junction is not well defined, which is essential for the production of good quality Schottky diode, which exhibits ideality factor close to the unity and low turn-on voltage. In order to avoid these two problems, in the present research was proposed to manufacture an organic diode with the semiconductor polymeric layer deposited over bimetallic (gold and aluminum) interdigitated electrodes. The doping of the active layer was performed by immersing the device in hydrochloric acid solution with pH 2 during different times in order to promote different doping levels of the semiconductor polymer. Was verified that the proposed diode, which exhibits well-defined metal-semiconductor junction, operates as a Schottky diode, with good ideality factor, 10 ± 3, and low turn-on voltage, 1,2 ± 0,2 V, in comparison with conventional organic polymeric diodes. Contrasting with the ideality factor and turn-on voltage, the diode rectification ratio was obtained as 7, a value lower than the expected for a good organic diode. Was also showed that the diode characteristics were dependent on the semiconductor polymer doping level, and that the diode characteristics were optimized with doping promoted by immersion in the acid solution for times longer than 50 s. Furthermore, as was showed that the diodes properties are dependent on the semiconductor...

This paper presents a multi-agent architecture that was designed to develop processes supervision and control systems, with the main objective to automate tasks that are repetitive and stressful, and error prone when performed by humans. A set of agents were identified, based on the study of a number of applications found in the literature, that use the approach of multi-agent systems for data integration and process monitoring to faults detection and diagnosis, these agents are used as basis of the proposed multi-agent architecture. A prototype system for the analysis of abnormalities during oil wells drilling was developed.

This article aims to analyze the content expressed in the weekly Bundas and show how this addressed the economic issues in Brazil in the period 1999-2001. Through this study, we will seek to understand how the printed addressed the economic issues and the language employed by evidence how the vehicle was differed from the others in the category accessibility. The economic journalism has a way of approach often incomprehensible by readers, so the analysis of Bundas show the role of that journalism to the society and the importance of it becoming available to the reading public.
