Recent development in electronics and wireless communications has enabled the improvement of low-power and low cost wireless sensors networks. Wireless Sensor Networks(WSNs) are a combination of autonomous devices transmitting locally gathered information to a so-called sink node by using multihop wireless routing. One of the most important challenges in WSNs is to design energy efficient routing...
The flow of compressible and incompressible fluids through channels with wavy walls is encountered in many engineering applications. There have been attempts to predict the distribution of fluid parameters like pressure, temperature etc using numerical and experimental investigations. In some cases mass flow estimation is the objective of analysis and in other cases heat flux enhancement is the objective...
The thermal diffusion behavior of ion-implanted Arsenic (As) in SiGe alloy has been investigated and modeled. This paper introduces an empirical model consisting of physics-based and process parameters for evaluating the effective diffusivity of Arsenic through SiGe accurately. The process parameters that were found to dominate the enhancement in arsenic diffusion were the Germanium content, diffusion...
The behavior of an aircraft can be described with a set of non-linear differential equations by assuming six degrees of freedom (3 for linear motions and 3 for angular motions) about x, y & z axis. All the aircrafts have a PID controller for autopilot control system for pitch, yaw and roll. The PID [6, 12] controllers are associated with their PID gains which can either be tuned manually or by...
Fourier domain methods have had a long association with geometric vision. In this paper, we introduce Fourier domain methods into the field of visual servoing for the first time. We show how different properties of Fourier transforms may be used to address specific issues in traditional visual servoing methods, giving rise to algorithms that are more flexible. Specifically, we demonstrate how Fourier...
