Heterogeneous platforms integrating several CPU cores and GPU accelerators have established in several application domains, from desktop, server and mobile. To take full advantage of such platforms, video encoders/decoders have to exploit a broader design space, by cooperatively executing in all the available CPU and GPU cores. To attain such objective, three novel contributions that aim the ex...

Although open source software (OSS) has been widely implemented in the server environment, it is still not as widely adopted on the desktop. This chapter presents a migration model for moving from an existing proprietary desktop platform (such as MS Offi ce on an MS Windows environment) to an open source desktop such as OpenOffi ce on Linux using the Gnome graphical desktop. The model was inspi...

Database management systems are today’s most reliable mean to organize data into collections that can be searched and updated. However, many DBMS systems are available on the market each having their pros and cons in terms of reliability, usability, security, and performance. This paper presents a comparative study on the performance of the top DBMS systems. They are mainly MS SQL Server 2008, ...

The evaluation of the Signal to Interference Ratio (SIR) in cellular networks is of primary importance for network dimensioning. For static studies, which evaluate cell capacity and coverage, as well as for dynamic studies, which consider arrivals and departures of mobile stations (MS), the SIR is always an important input. Contrary to most of the analytical works evaluating SIR, we assume in t...

ABSTRACT A learning management system (LMS) provides the platform for web-based learning environment by enabling the management, delivery, tracking of learning, testing, communication, registration process and scheduling. There are many LMS systems on the market that can be obtained for free or through payment. It has now become an important task to choose the correct LMS for a web-based educat...

We propose an integrated gateway for various personal health devices (PHDs). This gateway receives measurements from various PHDs and conveys them to a remote monitoring server (MS). It provides two kinds of transmission modes: immediate transmission and integrated transmission. The former mode operates if a measurement exceeds a predetermined threshold or in the case of an emergency. In the la...
