An efficient and secure group communication in Mobile Adhoc Network (MANETs) has brought attention to many security issues. In this paper, we propose Energy Efficient Dynamic Core based Multicast Routing Protocol to establish the path between the nodes that participate in group communication. During the routing process each node computes a Pythagorean Triple and constructs a Pythagorean Triple ...

The real Cloud and Ubiquitous Manufacturing systems require effectiveness and permanent availability of resources, their capacity and scalability. One of the most important problems for applications management over cloud based platforms, which are expected to support eficient scalability and resources coordination following SaaS implementation model, is their interoperability. Even application ...

The improvement of the Brazilian system of interactive Digital Television (iDTV) has amplified usage perspectives for television in the educational realm, due to new possibilities of interaction. Thus, there is a growing discussion over the development of educational content that will address the needs of this new reality. The present article describes concepts of the technological, communicati...

As traditional oblivious transfer protocols are treated as a cryptographic primitive, they are usually executed without the consideration of possible attacks, e.g., impersonation, replaying, and man-in-the-middle attacks. Therefore, when these protocols are applied in certain applications such as mental poker playing, some necessary mechanism must be executed first to ensure the security of sub...

Organizational climate is a situation in an organization, where each member interacts with other, limits themselves, or other so as to improve the quality of cooperation and organizational satisfaction. satisfaction members organization regarding their work, supervision, wages profits, assessment achievements, peers. The purpose this study was determine relationship between communication dormit...

The exponential growth of Facebook during the last year, was followed by a vital public discourse and often an alert with regard to the impacts of this popular SNS on communicational and behavioural attitudes and users’ rights. In this Paper we focus on privacy issues relating to Facebook. We attempt to define the “phenomenon Facebook” as a social and communicational ecosystem in the context of...

This is an experience developed during the Master program in Nursing at UFSC. It aimed to reflect on the nursing care delivered to the patient unable to verbally communicate, based on Paterson and Zderad's Theory and to analyze the communicational process between nursing and client. The experience was carried out in the Intensive Care Center of a private hospital in two stages: non-participatin...

This paper reports the results of a multi-agent simulation designed to study the emergence and evolution of symbolic communication. The novelty of this model is that it considers some interactional and spatial constraints to this process that have been disregarded by previous research. The model is used to give an account of the implications of differences in the agents’ behavior, which are emb...

A new class of parallel algorithms is introduced that can achieve a complexity of O(n 3 2 ) with respect to the interprocessor communication, in the exact computation of systems with pairwise mutual interactions of all elements. Hitherto, conventional methods exhibit a communicational complexity of O(n). The amount of computation operations is not altered for the new algorithm which can be form...

As traditional oblivious transfer protocols are treated as cryptographic primitives in most cases, they are usually executed without the consideration of possible attacks, e.g., impersonation, replaying, and man-in-the-middle attacks. Therefore, when these protocols are applied in certain applications, such as mental poker game playing and fairly contracts signing, some extra mechanisms must be...
