In these modern research areas the Nonlinear Dynamics is a very popular topic, the researchers study the nonlinear behaviour of every system which can be an industrial machine/instrument or a theoretical aspect. Prior researchers already studied the nonlinear dynamics of Current Controlled DC-DC Boost Converter. But the Power Factor Corrected Boost Converter is a circuit which is used in very p...
Long distance AC transmission is often subject to stability problems , which limits the transmission capability.Large interconnected power systems often suffer from weakly damped swings between synchronous generators and subsystems.This paper presents two methods , based on the use of nonlinear system model , to improve transient stability and damping of power swings using UPFC. A statevariable...
According to many psychological and social studies, vocal messages contain two distinct channels—an explicit, linguistic channel, and an implicit, paralinguistic channel. In particular, the latter contains information about the emotional state of the speaker, providing clues about the implicit meaning of the message. Such information can improve applications requiring human-machine interactions...
This paper describes a fully integrated neural recording front-end comprising a low-noise two-stageamplification circuitry and a 10-b successive approximationregister (SAR)-based ADC as part of a fully implantable brain-machine-brain interface (BMBI) device for neuroanatomical rewiring of cortical circuitry in an injured brain. Fabricatedusing the TSMC 0.35 μm 2P/4M n-well CMOS ...

The impact of fixed speed squirrel cage type as well as variable speed doubly fed induction generators (DFIG) on dynamic performance of a multimachine power system has been investigated. Detailed models of the various components have been presented and the integration of asynchronous and synchronous generators has been carried out through a rotor angle based transform. Simulation studies carrie...
Open-end winding induction machines fed from two standard two-level voltage source inverters (VSI) provide an attractive arrangement for AC drives. An alternative approach is to use a dual output indirect matrix converter (IMC). It is well known that IMC provides fully bidirectional power flow operation, with small input size filter requirements. Whilst a standard IMC consists of an AC–DC matri...
This paper presents system stability analysis of DFIG based wind energy conversion system. Presently for variable wind speed DFIG is considered as efficient machine to generate the power. In addition to this advanced AC/DC/AC converters with closed loop control system has been presented. For stability analysis 1.5MW wind turbine has been considered. As the speed of the wind varies by ± 18% to 2...
Rapid color degradation during processing and storage is a limitation when using strawberry puree (SP). This work aimed to use image analysis coupled with two machine learning algorithms: ordinary least squares (OLS) artificial neural networks (ANNs), predict anthocyanin content (AC) in frozen SP its at –18°C for 120 days. When applying the OLS regression model, unsatisfactory AC prediction val...
