We present a novel analytical approach to computing the population and geometric parameters of a multi-robot system that will provably produce specified boundary coverage statistics. We consider scenarios in which robots with no global position information, communication, or prior environmental data have arrived at uniformly random locations along a simple closed or open boundary. This type of scenario...
This paper presents a fuzzy based approach for 3PL (Third Party Logistics) selection. A multi criteria decision making (MCDM) is used for 3PL evaluation. The MCDM proposal for 3PL evaluation incorporates the decisions of multiple decision makers belonging to the Performance Evaluation Team (PET) constituted by a buyer company. The selection is based on overall score obtained by the 3PL. The fuzzy...
In this work, a reconstruction of the sensor-based tracking control in a platoon of autonomous vehicles is developed. This control is reproduced with accuracy in the absence of data from the laser rangefinder. Only the velocity of each involved vehicle in the platoon is considered, as well as the inter-vehicle communication. This reconstruction occurs when the laser rangefinder is disturbed or failed...
The solid state power amplifier applications are in airbone radars, Missiles and communication systems. It offers a peak power output of 400watts. We designed the SSPA using Ghorbani model. Due to the Non Linearity nature of SSPA, both power and spectral efficiency of the signal is reduced. To improve signal power and spectral efficiency of a 16QAM modulated signal, we linearize SSPA by Predistortion...
In this paper, the nodal price for real and reactive power considering different reactive power price cost calculation methods for generator reactive power has been presented. The impact of FACTS controllers has also been considered taking their cost function into account. The comparison of fuel costs, reactive power cost, and cost of FACTS devices, and their impact on nodal price determination has...
With the advent of Wireless Sensor Networks (WSN's) covering a whole gamut of applications which is getting broader by the day and it is indeed necessary to study the nuances in WSN out of which aforementioned is one. WSN's consists of large number of deployed sensor nodes and a base node for aggregating data from deployed sensor nodes. Wireless Sensor Network's (WSN) are attribute based and they...
In this paper, we propose a new throughput analysis for IEEE 802.11 distributed coordination function (DCF) considering the real channel conditions and capture effects under arbitrary load conditions employing basic access method. The aggregate throughput of a practical wireless local area (WLAN) strongly depends on the channel conditions. In real radio environment, the received signal power at the...
