Dog-human communication has been widely investigated recently for different theoretical reasons, in most cases through dogs’ comprehension of human gestural cues. Dogs have been reported to be very skilful in comprehending a variety of human pointing gestures in many independent studies. This paper provides a short overview of the possible explanations behind the dogs’ exceptional communication...

ally disordered parent, he lacks the ability to think clearly, comprehend communicate and solve problems in an increasingly complex world. Thus, " breakdowns" occur at times of greatest stress (e.g., separation from home or cotwin, death of a grandparent, etc.) when his limited resources are overtaxed to the point of disorganization. By way of contrast, the cotwin has many more cognitive, commu...

An approach to improve communication processes in e-learning is introduced. Based on a separation of a content-related and a communicational part of e-learning environments a system to support both students and tutors in their communication endeavors is presented. The communication platform consists of administration, configuration, moderation, and certainly communication tools which are descri...

In 2008, Wang et. al. first investigate a sort of specific secure multi-party computation--secure convex hull two-party computation, and construct two protocols based on Gift wrapping method and Quick method separately. However, there are some errors in his protocol based on Quick method. This paper proposes two effective improved protocols. In addition, we analyze and compare security, computa...

Without an environment, an agent is effectively useless. Cut off from the rest of its world, the agent can neither sense nor act. An environment provides the conditions under which an entity (agent or object) can exist. It defines the properties of the world in which an agent will function. Designing effective agents requires careful consideration of both the physical and communicational aspect...

In this paper we analyze the term “WBT” from different perspectives and claim that the authoring, communicational and data access tools currently available on the Internet are not sufficient to fully exploit the tremendous educational power of the largest information and communication resource mankind has ever had. We contend that primitive hypermedia node-link data model and its most prominent...

Choosing the best access technology for delivering broadband services, is an important and complex step in moving toward NGN, specially in non-developed and developing countries. This paper, proposes a simple classification of users due to their communicational needs, and recommends the most appropriate access method for each class of users, considering network infrastructure in non-developed a...
