800x600 as a tendency to use new technologies, gadgets such as laptop computers are becoming more popular among students, teachers, businessmen and office workers. today laptops are a great tool for education and learning, work and personal multimedia. millions of men, especially those in the reproductive age, are frequently using their laptop computers on the lap (thigh). over the past several...

This dissertation thesis deals with cryptographic random and pseudorandom data generators in mobile computing environments (such as mobile phones, personal digital assistants, cryptographic smartcards). These mobile devices are typically bounded by the amount of energy, performance, memory or even silicon area. This lack of resources leads to very limited computing environments with: a) limited...

Wireless sensor networks efficient collection data with hundreds and thousands of sensor nodes is very complex task. Recently, mobile agents have been proposed for efficient data dissemination in sensor networks. In the traditional client/server-based computing architecture, data at multiple sources are transferred to a destination; whereas in the mobileagent based computing paradigm, a task sp...

Mobile information systems are often distinguished as traditional information systems with additional support for mobile devices. This idea is based on the mostly used cellular network architecture. Mobile units have to be wirelessly connected via a base station to a server integrated in a fixed network if their users want to use the capabilities of the information system which are provided by ...

This study presents the design and development of a novel mobile wireless system to be used for monitoring seismic events and related electromagnetic signals, employing smart mobile devices like personal digital assistants (PDAs) and wireless communication technologies such as wireless local area networks (WLANs), general packet radio service (GPRS) and universal mobile telecommunications syste...

This study aimed to characterize spatial/temporal variations of ambient volatile organic compounds (VOCs) using a community-scale monitoring approach and identify the main sources of concern in Paterson, NJ, an urban area with mixed sources of VOCs. VOC samples were simultaneously collected from three local source-dominated (i.e., commercial, industrial, and mobile) sites in Paterson and one ba...

This paper presents the problem of application of modern developments in the field of bio-energy for the development of autonomous mobile robots’ power sources. We carried out analysis of biofuel cells, gasification and pyrolysis of biomass. Nowadays, very few technologies in the bioenergy field are conducted with regards to the demands brought by robotics. At the same time, a number of technol...

Advances in wireless networking technology and portable computing devices have led to the emergence of a new computing paradigm known as mobile computing and a number of applications. As a result, software applications have to be redesigned to take advantage of this environment while accommodating the new challenges posed by mobility. As mobile users wander about, they are bound to encounter a ...

The article presents a concept of Dezert-Smarandache theory application for enhancing security in tactical mobile adhoc network. Tactical MANET, due to its specification, requires collection and processing of information from different sources of diverse security and trust metrics. The authors specify the needs for building a node’s situational awareness and identify data sources used for calcu...
