The demand for Wireless Networks has increased rapidly downloading and uploading all types of data, which is due to the inefficiency high cost infrastructure based cellular Networks. Unmanned Aerial Vehicle (UAVs) reliable solution improving efficiency, latency redundancy, business, troubleshooting problems on a scale. Although, deployment UAVs meet user in any environment or region quite thoug...

social-cultural anthropology today one is usually referring to communication and culture. This is to say, when anthropologists use the term ‘media’, they tend to remain within a largely popular semantics, taking ‘media’ to mean communicational media and, more specifically, communicational media practices, technologies and institutions, especially print (Peterson 2001; Hannerz 2004), film (Ginsb...

In this paper we propose a computational model for human-agent and agent-agent conversation. This model has two fundamental characteristics: (1) it takes into account the implicit aspects of conversations by dealing with the non literal level of speech acts; (2) it models the dialogization process. Theoretically, our model uses a public approach based on social commitments and on what we call c...

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...

Contemporary digital learning environments, such as tangibles, mobile and sensor-based technologies are inherently multimodal, both in terms of representation modalities and interaction modes. Drawing on social semiotics, multimodality offers a valuable approach for analysing video data, as it systematically attends to the interpretation of a wide range of communicational forms (e.g. gaze, post...

A secure scheme of restrictive partially blind signature was presented. The proposed scheme has several advantages over the previous scheme: 1. The scheme is provable secure against the one-more signature forgery under the adaptively parallel attack. 2. The issued signatures can be of polynomial number whereas the previous work allows only logarithmic number. 3. The scheme is more efficient tha...
