Neural networks are commonly used to model brain functions and to resolve a variety of information that the brain receives. 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.

In the current era, Digitization has taken day-to-day utilities starting from a cab to grossary on the internet. 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.

Direction-of-arrival (DOA) estimation has been a challenging problem in many applications such as wireless communication, radar, radio astronomy, sonar and navigation. 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.

In recent time, multi-server environment is used to provide convenient and efficient online services that demand efficient authentication schemes for practical applications. However, single server authentication(SSA) scheme are not applicable to the multiple-server environment. Unlike, SSA scheme, in multiserver authentication scheme (MSA) user registers only once but get services at any time. A MSA scheme is the need of the modern age online services. Hence, we propose a MSA uses based on three factors and use Chebyshev chaotic map. We prove that the scheme is resistant to various active and passive attacks. As compared to other related schemes, it has less computational cost and communicational cost. The AVISPA tool is used for formal verification of the scheme. Low computational cost and communicational cost shows the efficiency and practical use of the proposed scheme.
近年来，多服务器环境被用于提供方便、高效的在线服务，在实际应用中需要高效的认证方案。但是，单服务器认证(SSA)方案不适用于多服务器环境。与SSA方案不同，MSA (multi - server authentication scheme)方案中用户只注册一次，但可以随时获得服务。MSA方案是现代在线服务的需要。因此，我们提出了一种基于三因素的MSA使用方法，并使用Chebyshev混沌映射。我们证明了该方案能够抵抗各种主动和被动攻击。与其他相关方案相比，该方案具有较低的计算成本和通信成本。使用AVISPA工具对方案进行形式化验证。较低的计算成本和通信成本表明了该方案的有效性和实用性。

In an era where communicating with anyone over the Internet is commonplace and services have risen to popularity, only to be replaced by something better, Internet Relay Chat (IRC) remains a method that many people are still using. Introduced in 1988, it is a protocol that has truly withstood the test of time. We created an App (application) for the Android ecosystem that can connect to IRC servers and allow the user to communicate with others on any channel they have access to on the server. The App uses an open-source Java library called Pircbotx as the backend for handling interactions with the server. The App offers minimal features to emphasize its primary purpose: communication. The interface was designed with the Android Material Design Guidelines in mind to give it a consistent appearance with other apps in the ecosystem. Any file access that was required was handled through a library called Paper.

In this research article, an active configuration is proposed which acts similar to a impedance multipliar configuration. This configuration is able to increase or decrease the impedance of any grounded passive network. The presented circuit configuration employs two VDCCs and three grounded resistances along with the impedance to be multiplied. The scaling of impedance can be achieved through resistance variation or bias current variation. The use of only grounded passive elements enhance the suitability for on-chip integration. The working of the presented design has been investigated under non-ideal environment. The validation of behavior of the proposed multiplier circuit has been confirmed by designing and simulating an active filter. All the simulations have been performed in PSPICE Environment with $0.18 mumathrm{m}$ CMOS technology.

Wireless power transfer is the method of transferring electrical energy from source to electrical load without using any physical contact. 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.
