High-dimensional data can be converted to low-dimensional codes by training a multilayer neural network with a small central layer to reconstruct high-dimensional input vectors. Gradient descent can be used for fine-tuni...

In wireless mobile ad hoc networks, packet delivery is achieved through two closely related network-layer operations: ad hoc routing and packet forwarding. As a result any security solution should encompass the protectio...

Social network sites (SNSs) are increasingly attracting the attention of academic and industry researchers intrigued by their affordances and reach. This special theme section of the Journal of Computer-Mediated Communic...

We have developed a near-real-time computer system that can locate and track a subject's head, and then recognize the person by comparing characteristics of the face to those of known individuals. The computational appro...

This research work analyzes the universal mobile telecommunication system (UMTS) authentication and key agreement (AKA) protocol, which suffers from the traffic bottleneck at home location register and authentication cen...

Neste trabalho realizou-se um estudo da qualidade dos produtos para a saúde em um Hospital da Rede Sentinela com o objetivo de subsidiar a ANVISA e melhorar a segurança na utilização destes produtos. O estudo teve ca...

Time underlies many interesting human behaviors. Thus, the question of how to represent time in connectionist models is very important. One approach is to represent time implicitly by its effects on processing rather tha...

This paper reviews the origins and definitions of social capital in the writings of Bourdieu, Loury, and Coleman, among other authors. It distinguishes four sources of social capital and examines their dynamics. Applicat...

There are considerable number of approaches to policy specification both for security management and policy driven network management purposes as reported in [20]. This specification sort security policies into two basic...

With the continuous expansion of data availability in many large-scale, complex, and networked systems, such as surveillance, security, Internet, and finance, it becomes critical to advance the fundamental understanding ...
