In the last few years the issue of energy-efficient network design has gained increasingly more importance [1], [2], both in academia and in industry. Information and communication technologies (ICT) represent about 2% of the entire world’s energy consumption, and the situation is likely to reach a point where ICT equipments in large cities will require more energy than is actually available [3...

On-line coupling of an automated flow system with a commercially available capillary electrophoresis (CE) system with an electrospray interface (ESI) for mass spectroscopic (MS) detection is described. The peculiarities of CE-ESI-MS interfaces, in which a high electrical field must be applied to the capillary end where the sample is provided by the flow system, introduce significant difficultie...

This study was designed to assess the extent of implementation of an ICT (ICT) program for secretaries at the staff training centers in southwestern Nigeria. Based on the available literature, a 29-item questionnaire using a four-point scale was developed and used in this study. The population of this study was made up of all ICT teachers and all secretaries in training at the Staff Training Ce...

Voltage Sag is one of the Power Quality problem and it become severe to industrial customers. Voltage sag causes miss operation to several sensitive equipments. This problem can be mitigating with the Dynamic Voltage Restorer. DVR is a solid state device which is connected in series between the source and load voltages. In this Dynamic Voltage Restorer is implemented using Capacitor Clamped Mul...

The visually impaired are the people who can have permanent or temporary loss of vision. Such people cannot see, read or write as the normal human beings. There are several substituting equipments and aid to help them lead a normal life. Similarly to read, Braille notations are being used. These Braille editions are not available for each text book. Thus to help them read the conventional text ...

By introducing video-quality adaptation mechanisms into intermediate network equipments using active network technologies, we can provide users with video distribution services taking into account client heterogeneity in terms of available bandwidth, performance of client systems, and user’s preferences about video quality. In this paper, we implement the low-pass filter, a quality adjustment t...

Since critical socio-technical systems include people interacting with equipments in workplaces, their intrinsic reliability problems have been concerned with both these two “actors”. Air Traffic Control (ATC) is going to be such a system in which controllers use a large number of distributed software tools to provide safety ATC services. The reliability of these services relies on the availabi...

Computer and other digital electronic equipments can emit unintentional electromagnetic signals in the state of information processing. The compromising electromagnetic emanations allow eavesdroppers to reconstruct processed data at a distance that threatening the information security. As result all equipments handling confidential information do need TEMPEST security testing. This paper attemp...
