The earlier methods of centre manifold and multiple scales of order reduction of a delayed nonlinear system offer a serious challenge in analyzing Hopf bifurcation of a general delayed system. To overcome this challenge a standard procedure called Harmonic balance approach is used to analyze the stability and bifurcations of limit cycles. This paper analysed the bifurcation and stability for Hopfield network employing a two delays neural network. Using Harmonic balance approach, we have carried out Hopf bifurcation and stability analysis to obtain the periodic solutions. The stability of the bifurcated periodic solutions is examined along with the theoretical analysis. Nyquist criterion has been used to determine stability of the model. The critical values under which Hopf bifurcation occurs is determined. The analysis reveals that the stability of the solutions is guaranteed only inside the interval from 0.6 to 1.1. Results of mathematical simulation of frequency, phase and waveform with different phase angles are also presented.","PeriodicalId":344030,"journal":{"name":"2019 6th International Conference on Signal Processing and Integrated Networks (SPIN)","volume":"178 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124406973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All the service providers heavily leverage IT and IT Services. Web Application plays a significant role in providing these services. While Digital opens infinite opportunities to increase business and enhance delivery, it also exposes business to an unseen world of cyber-attacks. To prevent the business from digital dysfunctioning, organizations pro-actively and continuously perform Vulnerability Assessments & Penetration Tests on their IT Assets (i.e. Web Applications, Network Devices, Servers, Security Devices, etc.). However, quite often such scans become time consuming and generate unreliable results and none of the tools can find out the effective vulnerability. However, with a set of combined tools in one framework, it is possible to increase the coverage of vulnerability issues. The aim of the research is to present two approaches: (1) Web application vulnerability discovery through a set of web application vulnerability scanners and its integration on the same framework (python as scripting engine) using multi-threading technique (to reduce the scan time). (2) Mitigation of the detected web application vulnerabilities by customizing configuration rules through web application firewall ModSecurity.","PeriodicalId":344030,"journal":{"name":"2019 6th International Conference on Signal Processing and Integrated Networks (SPIN)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126969618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the resolution of the Direction-of-Arrival estimation can be intensified by an array antenna system with an inventive signal processing. The DOA based estimation for the multiple-input-multiple-output (MIMO) systems have been observed using MUSIC and Wavelet Packet Decomposition on Rayleigh and Rician fading models. Furthermore, in wireless communication, the transmission of signal can be unexpectedly hindered due to a number of obstacles including severe weather conditions like rain that leads to fading of the signals resulting in loss of partial information. The MUSIC algorithm has however, been a winning solution to many parameter estimation problems due to its low computational cost, high resolution, and better stability. The presented methods have been useful to detect the fading scenario for MIMO system and several theoretical and practical simulations also show the effectiveness of this proposed algorithm. This paper thus puts forth an effective parameter to analyze and simulate the DOA evaluation in a wireless communication over fading channels in MIMO systems, which has been augmented on MUSIC and Wavelet Packet Decomposition so as to intensify the performance characteristics and reliability.","PeriodicalId":344030,"journal":{"name":"2019 6th International Conference on Signal Processing and Integrated Networks (SPIN)","volume":"237 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122054099","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the most common magnetic couplings is the resonant inductive power transfer (RIPT). It is a system which is composed of at least two magnetically coupled coils called sending end coil and receiving end coil which is forced to operate at resonance to make the circuit appear pure resistive. In this paper simulation of two coil inductive wireless power transfer is described with the help of class-E resonant high frequency inverter. The high frequency inverter used in this system is resonant class-E converter which is operated at 1 MHz switching frequency. To minimize the switching loss, soft switching technique has been implemented i.e. switching of semiconductor device is done at instant where the voltage is zero which is called as zero voltage switching (ZVS). At the end, calculated values of efficiency, sending coil quality factor, receiving coil quality factor, resonant frequency and bandwidth is summarized.","PeriodicalId":344030,"journal":{"name":"2019 6th International Conference on Signal Processing and Integrated Networks (SPIN)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121508480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
