This book lights on data attack strategy which is called Black Hole Attack in MANET under Ad-hoc on Demand Distance vector (AODV).In this book, we discuss the working of AODV protocol, MANET, a data packet, nature of Black Hole Attack. This proposed solution first detects and then prevent this attack by using intelligently transform source node which I named Fox node. I proposed a ´´Honey-Pot Technique´´ to make AODV networking more secure. In this modern era, there is a need to create a more secure networking environment to remove hacking and make eve dropper´s attempt unsuccessful. ´´In every morning every person wakes with a loop in their mind and constantly thinks about the loop statement, that loop contains a statement and iterates whole day in mind. Write your life goal in your mind´s loop then you will become successful to achieve your goal.´´ ´´In some situations, you need to use a Honey-pot to defeat evil.´´

Ambiguidade de nomes de autores é um grande problema enfrentado pela comunidade científica. Este problema ocorre quando vários autores publicam artigos usando nomes similares, ou quando um mesmo autor publica seus artigos com variações do seu nome. Tradicionalmente, existem métodos de desambiguação automáticos que são aplicadas a todos os registros de citação que estão no repositório de uma biblioteca digital. Mas existem métodos incrementais, que apenas desambiguam os nomes dos autores durante a inserção de um registro de citação no repositório. Estes métodos foram propostos com o objetivo de se obter uma maior eficiência. Porém, como efeito colateral, vários registros de um mesmo autor podem ser considerados como pertencentes a diferentes autores, causando o que é chamado fragmentação. Neste trabalho, é realizado um estudo para comparar estratégias visando reduzir a fragmentação dos registros sem comprometer a pureza, ou seja, mantendo os grupos de registros atribuídos a um autor com registros somente de um autor. As estratégias avaliadas foram baseadas em técnicas capazes de isolar os registros de citação possivelmente atribuídos incorretamente durante a desambiguação.

No mercado global, competitivo e em constante mudança consideramos ser importante que as Micro, Pequenas e Médias Empresas, enquanto parte significativa do tecido empresarial nacional, se tornem competitivas e, assim, entendemos importante avaliar como o nível de envolvimento no Comércio Eletrónico (CE), em relações Business-to-Consumer, pode influenciar o sucesso de uma microempresa do setor de comércio a retalho, com foco na sub-região portuguesa Pinhal Interior Norte. Sendo uma região que está longe das grandes metrópoles, de onde a população mais jovem e com maior nível de escolaridade se distancia, restando pouco mais do que a população mais velha e com menor nível de escolaridade, consideramos interessante estudar se as microempresas da região estão preparadas para a nova era da tecnologia como um modelo de negócio para as suas empresas. Conseguimos confirmar que 62,50% das empresas analisadas viu o seu resultado financeiro aumentado após a adoção do CE, o que nos permite estabelecer a existência de uma relação entre os dois factos.

A técnica proposta neste livro para determinação de pontos de interesse robustos à variação de iluminação visa diminuir o tempo necessário para a correspondência entre imagens em alta definição. A pesquisa indica também uma metodologia no formato de framework conceitual, que, baseada na teoria de aprendizagem situada, correlaciona os aspectos educacionais e tecnológicos próprios ao contexto do desenvolvimento de aplicações de RA móvel. Com base nos experimentos realizados, é possível observar que a técnica que utiliza os pontos robustos, representa economia de, aproximadamente, 70% no tempo necessário para a correspondência entre imagens em alta definição.
