As campanhas de publicidade online sobre pesquisas em motores de busca têm um grande peso nas receitas das empresas de marketing digital. Cada campanha é definida por um conjunto de palavras chave que são utilizadas pelo motor de busca para escolher a melhor publicidade candidata a apresentar juntamente com os resultados da pesquisa. Um problema com que se deparam estas campanhas é a da sugestão das melhores pa...
Delay Tolerant Networks (DTN) give a base of communication that permits the delivery of data within harsh environments or even between networks without interconnection. The connection between networks happens when some nodes cross between them and carry information. Our model consists of the Message Ferry Mobility Model (MFMM) where all nodes in the network are confined to their village except one mobile node (...
The problem of interference is likely to be commonplace in deployed ubiquitous computing systems. A conceptual framework was proposed in [1] to help researchers address this problem. Evaluating conceptual frameworks such as this is a challenging task; one approach to do so is to de- sign and conduct user studies of how researchers address interference using such frameworks. In this paper we pro- vide insights o...
Future ubiquitous computing environments are likely to consist of numerous interacting components, many of which will have been developed in isolation from each other. Unless appropriate measures are taken, interference (where a component's behavior in a deployed system differs from its behavior when in isolation) is likely to be commonplace. In this paper we explore the importance of this problem and present o...
