Wireless Sensor Network (WSN) consists of hundreds of sensor nodes, which are tiny, low cost, low power radio devices. These nodes are dedicated to perform certain functions such as sensing the environment, collecting the sensed data from the surrounding area, processing those data and send the information to the observer. One of the major challenges in WSN is to cover the desired area which is used...
In this paper a fuzzy logic controller for Solar powered DC -DC boost converter is planned. Here for simplification, the PV system is taken as a constant DC Voltage source. The output response of the boost converter, is controlled by changing its duty cycle and the controller is planned to change the duty cycle. The simulation is formulated by MATLAB simulation program and PSIM software. Using fuzzy...

Many complex systems of theoretical and practical interest can be modeled as hybrid systems, i.e., systems that exhibit both continuous and discrete dynamics. This work focuses on the explicit predictive control of hybrid systems using two free Matlab/Simulink toolboxes designed specifically to synthesize and simulate controllers for this kind of systems. A case study is considered. The system is...
Historically, all engineering systems have been studied, analyzed and implemented by approximating the governing dynamics associated with the system by an Integer Order model. Although these models were able to replicate a close to real time working behavior, an exact model of these systems was always subject matter of research. With the advancement in technology an accurate model understanding of...

Recently there has been renewed interest in the application of photoplethysmography signals for cardiovascular disease assessment. Photoplethysmography signals are acquired non-invasively using visible and infrared light passed through the finger pulp. Unfortunately, this method commonly suffers from many forms of interference and distortion such as; baseline wander, mains-line interference and random...
Electricity demand is mounting around the world due to increased world population. For the years, conventional energy resources have been employed for the purpose of power generation. Rapid depletion plus their environmental and economic concerns has challenged the compatibility of conventional resources to deal with this mounting electricity demand. Therefore, it is necessary to exploit the renewable/alternative...
This paper describes a new technique for simulating the guidance of a SAM (surface to air missile) without the help of a controller. This analysis is fully automated in a closed loop using the features of commercial software MATLAB. The guidance algorithm is simulated with the help of aerodynamic data. Control law is not used for obtaining the desired deflections of the control surfaces rather reverse...

This paper reviews many lower and upper bounds for consecutive-k-out-of-n systems presented over the last three decades. The reason is a revived interest to accurately estimate the reliability of (very) large consecutive systems, where exact calculations can be challenging. Main examples are novel nano-architectures targeting FinFETs, nano-magnetic and molecular technologies (where accurate estimations...
A surface Electrogastrography (EGG) system uses electrodes placed on the abdomen of the patient to verify the gastric myoelectric activity. Physicians use EGG systems to aid the patients' diagnosis with gastric disorders. In this context, the results of the EGG examinations must be accurate to avoid errors on the patient's evaluation. The medical device and the software to control the device must...
