This document presents a quantitative analysis of the direct and relative throughput of IEEE 802.11e.
The global throughput of an 802.11e WLAN is determined by EDCA (Enhanced Distributed Channel Access) parameters, among other aspects, that are usually configured with predetermined…

Government Information Sharing (GIS) allows information exchange and integration between different government departments, agencies, as well as between public and private institutions. Sharing information enables enhanced efficiency -avoiding duplication of processes updating the same data; better quality of processes and…

At present there are different TCP versions providing different performances. In this work the three of them: Reno, CUBIC and Vegas are considered. We simulate a WAN type network analyzing the throughput and performance of these TCP variants in order…

Based on the need to update the language and tools used to teach Procedural Programming during the first year of computer science careers, a cross descriptive research was conducted by assessing different programming languages.
The analysis involved a total of…

To support multimedia applications, it is desirable that an ad hoc network has a provision of Quality
of Service (QoS). However, the provision of QoS in an ad hoc network is a challenging task due to its
inherent…

Based on our experience, in this paper we present the main aspects of two different approaches to implement low cost multi-touch tables: projection based and LCD based. The former uses a video projector to build a feedback image on the…

The Web Accessibility Initiative (WAI) defines the guidelines to facilitate access for people with disabilities to ICT. This article presents a proposal to promote the unification and improvement of the works of two authors, combining the procedures and considerations after…

The introduction of mobile wireless devices brings unique challenges for distribution of data to many devices simultaneously. An optimizing multicast methodology called Probabilistic Multicast Trees (PMT) is extended to handle mobile wireless devices. We will show that PMT multiple tree…

This dissertation formalizes a comprehensive approach based on compiler technology [3-5] to simulate some basic forms of automata viz., finite accepters, finite transducers, pushdown accepters and Turing machines. These basic forms of automata are known for their simplicity and generality,…

James Reinders (Chief Evangelist of Intel® Software at Intel) and Jim Jeffers (Principal Engineer at Intel)
have gathered in this book the working knowledge of the people involved to prototype and productize the Intel® Xeon Phi coprocessor. This include…
