A Prototype for the analysis of Conflict resolving Algorithms in Context aware Environment using simulation

Abstract: In this paper we are proposing a GUI based Prototype for user centered environment like class room, library hall, laboratory, meeting hall, coffee shop, kitchen, living room and bedroom, which recommends useful services based on the user’s context. Service recommendation is mainly based on parameters such as user, location, time, day and mood. In addition whenever the conflict arises among different users it will be resolved using some conflict resolving algorithms. The motivation behind the proposed work is to improve the user satisfaction level and to improve the social relationship between user and devices The prototype contains simulated sensors which are used to capture the raw context information, which is then described with meaningful English sentence and services are recommended based on user’s situation. The proposed conflict resolving algorithms are Rule based algorithm, Bayesian probability based algorithm and Rough set theory based algorithm. The amount of conflicts resolved by these algorithms is also analyzed at the end.

Crowd Anomaly Detection Using Motion Based Spatio-Temporal Feature Analysis

Abstract: Recently, the demand for surveillance system is increasing in real time application to enhance the security system. These surveillance systems are mainly used in crowded places such as shopping malls, sports stadium etc. In order to support enhance the security system, crowd behavior analysis has been proven a significant technique which is used for crowd monitoring, visual surveillance etc. For crowd behavior analysis, motion analysis is a crucial task which can be achieved with the help of trajectories and tracking of objects. Various approaches have been proposed for crowd behavior analysis which has limitation for densely crowded scenarios, a new object entering the scene etc. In this work, we propose a new approach for abnormal crowd behavior detection. Proposed approach is a motion based spatio-temporal feature analysis technique which is capable of obtaining trajectories of each detected object. We also present a technique to carry out the evaluation of individual object and group of objects by considering relational descriptors based on their environmental context. Finally, a classification is carried out for detection of abnormal or normal crowd behavior by following patch based process. In the results, we have reported that proposed model is able to achieve better performance when compared to existing techniques in terms of classification accuracy, true positive rate, and false positive rate.

Performance Analysis of P&O and INC MPPT for WECS

Abstract: By virtue of start of fossil fills overall warming expedited by normal issues, the raising expenses of unrefined oils and standard gasses. They hoist tenacious push to upgrade vitality framework and its proficiency. This paper presents reproduction and execution investigation of network associated WECS with MPPT calculation. The breeze control period structure uses wind turbine (WT), a permanent magnet synchronous generator (PMSG), a three-organize diode rectifier connect, dc/dc support converter, multilevel inverter with MPPT controller. Perturb and Observe (P&O) and Incremental Conductance (INC) is utilized for maximum power tracking. The execution of the created display is examined for constant and variable wind speeds. The wind control yield is contrasted and both MPPT calculations. Multilevel inverter is utilized to step up the voltage and to reduce the THD. The MATLAB/Simulink outcome demonstrates the power sharing amongst wind and the Network. At long last the most appropriate MPPT calculation is recommended for the matrix interface of wind vitality change framework.

Design of Compact Beam-Steering Antenna with a Novel Metasubstrate Structure

Abstract: This paper presents a compact beam-steering antenna in which both beam-steering capability and mutual coupling reduction has been achieved using a novel meta- substrate structure. This novel meta-substrate consists of a 1×2 slotted patch with a split between in which PIN diodes are incorporated and 6×1 complimentary hexagonal split ring resonator (CHSRR) etched on copper plate. It has been observed that by placing this novel meta-substrate structure above the 1×2 patch array antenna at an optimized height of 3 mm produces ±20° beam scanning with around 10 dB mutual coupling reduction and about 20% miniaturization as compared to conventional antenna. All simulations are carried out using Ansoft HFSS EM Simulator and the proposed antenna can be used for ISM band application in a wireless communication system.

Performance Comparison of Rectangular and Circular Micro-Strip Antenna at 2.4 GHz for Wireless Applications Using IE3D

Abstract: This paper compares the performance parameters of rectangular and circular micro-strip antenna for 2.4 GHz RFID wireless applications using IE3D simulation software. The main parameters of comparison are return loss, gain, and area. The main objective of the work is to obtain the reduction in the size of circular antenna compared to rectangular for same frequency of operation. Impedance matching between the feeder line and radiating patch is done using planar micro-strip transmission lines. Quarter wave feeding technique is used for both the antennas to provide best matching between antenna and the source. Simulation is done using IE3D simulation software and parameters like bandwidth, return loss, and gain are measured. Results are optimized using optimizing techniques and results are compared with practically measured results. Finally antennas are fabricated and tested using in-house facilities.
