A new approach to intrusion detection is needed to solve the problems of larger and faster networks and the constraints on system administrator’s time to manage security systems. Current network intrusion detection systems lack solutions to these two problems being complex in design and generally incurring larger costs in terms of operation and maintenance. We propose a new technique to solve t...

Mobile Ad Hoc Network (MANET) is a self-organized and infrastructure-less mobile network. Wireless Mesh Networks is self-configuration; self-healing and low cost adhoc network. Ad-hoc On-demand Distance Vector (AODV), in MANETs is an on-demand variation of the distance vector routing protocol. This protocol initiate route discovery only when a route is needed and maintain active routes only whi...

A method is introduced for determination of a vector network analyzer’s calibration residual errors for measurement of the reflection coefficient. The method utilizes unscented Kalman filtering and spline interpolation time domain techniques. All three residual errors are calculated by processing the measured reflection coefficient of a single verification device, such as an air line terminated...

Estimation of the conceptual costs in construction projects can be regarded as an important issue in feasibility studies. This estimation has a major impact on the success of construction projects. Indeed, this estimation supports the required information that can be employed in cost management and budgeting of these projects. The purpose of this paper is to introduce an intelligent model to im...
