High porosity porous silicon holds great promise for applications such as sensing where large surface area is required. However electrical measurements of films, and implementation into electronic devices, have thus far been limited due to the high resistance low mechanical strength films. In this work, microfabrication processes were refined then implemented enable studies films with 81%. Opti...

VANET (Vehicular Ad Hoc Network) is actually an important field for the development of a variety of services. In VANET charging and billing of services could not be enabled in the same way as in classical mobile and fix networks and MANET (Mobile Ad Hoc Network) because of the characteristics of such network namely the high speed of nodes, frequent disconnection between nodes, rapidly changing ...

A common element in emerging nanotechnologies is the increasing complexity of the problems to face when attempting the design phase, because issues related to technology, specific application and architecture must be evaluated simultaneously. In several cases faced problems are known, but require a fresh re-think on the basis of different constraints not enforced by standard design tools. Among...

e-banking (electronic banking) is the modified business banking toward e-business (electronic business) banking that actually uses the electronic communication channels such as internet, phones, cell phones and the like. by using this method, the demands of customers such as time independent and high flexible actions are satisfied. in this process, marketing is so important because guiding cust...
