In this paper, we present a fuzzy logic based scheme for a two hop energy harvesting (EH) wireless sensor network (WSN). Incorporating data and energy causality constraints, discrete transmission rates, finite energy and data buffers, a fuzzy model is developed which uses network throughput, battery level and channel gain as inputs. The fuzzy scheme is then compared with optimum, modified optimum,...
Early and efficient fault detection is very important in today's complex and sophisticated automated industry. For fault detection, many techniques have been employed among which the support vector machines (SVM) is a popular one owing to its many attractive features like fast classification, good handling capability of non-linear behavior of the data, and providing a global optimum for classification...
To ensure reliable operation of electric motors, various types of condition monitoring techniques are employed. Among them Electrical Signature Analysis (ESA) is a well-established technique for fault detection. ESA mainly consists of motor current signature analysis, instantaneous power signature analysis and extended Park's vector approach. While these techniques are very effective for fault detection...
Pulsed wave radars are very promising due to their numerous attractive features over traditional continuous wave radars. This paper presents the range and doppler estimation of moving targets using pulsed doppler radars. Various techniques have been implemented to correctly estimate the range and radial velocity of the moving target. Moving Target Indicator (MTI) is widely accepted as computationally...
Energy efficiency and reliability are big concerns in existing power systems. There are a variety of losses during transmission and distribution of electricity. In this paper we employ the concept of micro-grids which are scaled-down versions of the centralized electricity system for modeling and implementation ofa model village system. To control a model village system, three controllers are implemented...
Spectrum sensing is a vital part of Cognitive Radios (CRs). Success of CRs for opportunistic spectrum access depends upon the underlying spectrum sensing technique. Prior to choosing a particular technique among others, one of the biggest challenges faced is the hardware requirements of these techniques as they govern the cost of CR. This paper presents the complexity and performance analysis of filter...
This article describes a graphical approach for multi-standards SDR design formalization. An SDR consists of software components whose behavior can be changed by reconfiguration procedure. In a common operator design this change requires only an adjustment of certain parameters. The optimal way of realizing a multi-standards terminal is to identify the common functions and operators between standards...
