The Universal Mobile Telecommunication System (UMTS) is a third generation (3G) mobile communications system that provides a range of broadband services to the world of wireless and mobile communications. The UMTS delivers low-cost, mobile communications at data rates of up to 2 Mbps. It preserves the global roaming capability of second generation GSM/GPRS networks and provides new enhanced cap...
In recent years, mobile devices such as mobile phones, smartphones and hand-helds are becoming more and more prevalent. With the emergence of smartphones, the availability of advanced localization technologies, like the global positioning system (GPS), increased significantly. This in turn enables the widespread and often continuous use of location based services to deliver tailored information...
Abstract- Communication has become inevitably part of our day to day activities, in academic, business, banking, and other sectors. It has therefore become so important to implement good and efficient communication system. A reference point according to this research is the wireless sensor networking (WSN) system, and most important thing in communication is to be free from interference, attenu...
Augmented Reality (AR) enhances the real world environment with virtual information by embedding virtual objects in the real world to enhance the user’s life experience. Although AR technology has been around for fifty years, it has not been widely applied in practice until recent years when mobile phone technologies became more mature. Researchers have started to investigate the combination of...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
this research has been designed in order to provide an appropriate methodology for business model change and update based on applying new information and communication technologies such as mobile technology in an organization. in this way, after investigation of all related references in the field of business model, ict change, business model change and applying mobile technology in organizatio...
