Wireless Sensor Network (WSN), composed of a huge number of resource-constrained sensors can be used for a large number of securitysensitive applications. Regardless of the type of application, smooth collection and delivery of data from this type of network is one of the critical requirements. If the data supply process is hampered and thus the ex

المستخلص تهدف هذه الدراسة إلى بحث دواعي تأليف كتاب الرسالة للإمام محمد بن إدريس الشافعي. وقد وضعت الباحثة مجموعة فرضيات للبحث منها أن تأليف الرسالة كان بسبب طلب عبد الرحمن بن مهدي ومنها والرد �

Ad hoc network is a group of wireless mobile computers (or nodes), in which individual nodes cooperate by forwarding packets for each other to allow nodes to commu- nicate beyond direct wireless transmission range. Previous research in ad hoc networking has generally studied the routing problem in a non-adversarial setting by assuming a trusted env

This paper introduces a Role Based Access Control (RBAC) model for e-Village in creating and sharing knowledge in a secure way. This includes secure information about marketing to help the products become an innovation and highly valuable. As a case study, the Pasir Region, East Kalimantan, has the 100 families who moved were originally from Jepara

Hybrid electric vehicles (HEVs) powered by electric machines and an internal combustion engine (ICE) are a promising mean of reducing emissions and fuel consumption without compromising vehicle functionality and driving performances. This paper presents the design of an environmental friendly hybrid car that feature the gasoline engine and batterie

Different types of lattice spin systems with competing interactions have rich and interesting phase diagrams. In this study we present some new results for such systems involving the Ising spin system (i.e. � = �1) using a generalization of the Cayley tree-like lattice approximation. We study the phase diagrams for the Ising model on a Cayley t

Rain is a major source of attenuation for microwave propagation above 7 GHz. The problem of rain attenuation prediction has been studied along the years. In spite of the e®ort developed in di®erent parts of the world, there are yet some points to be clari¯ed. This problem is quite di±cult to be solved, mainly due to the complexity of rain struc

In recent years water pollution control and water quality management strategies are gaining prominence in developed as well as developing countries in the wake of global environmental scenarios like resource depletion, climate shifts, population pressure and last not the least, increased public awareness. In spite of all the efforts taken by the re

DENTURE PROSTHODONTICS ‘Complete denture prosthodontics’ is defined as that body of knowledge and skills pertaining to the restoration of the edentulous arch with a removable dental prosthesis. While ‘complete denture prosthetics’ is defined as: 1. the replacement of the natural teeth in the arch and their associated parts by artificial sub

This study focuses on the implementation of virtualization technology in data centers to provide efficient solutions for increasing the efficiency and performance of data center. Data centers are the building blocks of IT business enterprises providing the capabilities of centralized repository for storage, management, networking and dissemination
