Transportation electrification has undergone major changes since the last decade. Success of the smart grid with renewable energy integration solely depends upon the large-scale penetration of Plug-in Hybrid Electric Vehicles (PHEVs) for a sustainable and carbon-free transportation sector. One of the key performance indicators in the hybrid electric vehicle is the State-of-Charge (SoC), which n...
The Internet of Things (IOT) management platform is used to manage and transmit data from a variety terminal devices in the power system. In terms detecting abnormal data, existing IOT has low processing efficiency high error rate. addition, optimal selection determination structural parameters convolutional neural network (CNN) have substantial effect on its prediction performance. On this bas...
In this paper a novel hybrid algorithm for harmonics estimation in power systems is proposed. The estimation of the harmonic components is a nonlinear problem due to the nonlinearity of phase of sinusoids in distorted waveforms. Most researchers implemented nonlinear methods to extract the harmonic parameters. However, nonlinear methods for amplitude estimation increase time of convergence. Hen...
In this paper a hybrid adaptive particle swarm optimization aided learnable Bayesian classifier is proposed. The objective of the classifier is to solve some of the fundamental problems associated with the pure naive Bayesian classifier and its variants with a larger view towards maximization of the classifier accuracy. Further, the proposed algorithm can exhibits an improved capability to elim...
In this study, a new switched-capacitor-based seven-level inverter topology with photovoltaic system is presented. The proposed requires smaller number of devices and has the ability to self-balance voltage across capacitor. configuration simple extend higher levels voltage. This multilevel suitable for low- medium-voltage applications (PV) integration. To improve PV efficiency as an input DC–D...
A Dermatite Atópica (DA) é uma doença multifacetada de caráter genético, em que o paciente apresenta resposta imune exacerbada. Foi analisado padrão lesional e prurido cães das raças lhasa apso, yorkshire terrier, shih tzu pug ambos os sexos, já diagnosticados anteriormente com DA, atendidos entre janeiro 2017 a abril 2019 no Hospital Veterinário da Universidade Metodista, intuito verificar um ...
چکیده: امروزه سیستمهای قدرت با توجه به افزایش روزافزون مصرف انرژی الکتریکی در حاشیه پایداری کمتری نسبت به گذشته کار میکنند. افزایش وقوع خاموشیهای گسترده در سالهای اخیر در نقاط مختلف دنیا مبین این نکته است. استفاده از ادوات FACTS نقش مهمی در بهبود پایداری در سیستمهای قدرت دارد. یکی از ادوات FACTS کارآمد برای کنترل مجزای توان اکتیو و راکتیو خطوط UPFC است که باعث بهبود پایداری در سیستم قدرت م...
The subcommissural organ of vertebrates secretes glycoproteins into the cerebrospinal fluid of the third cerebral ventricle. This material polymerizes in Reissner's fiber. During ontogenetic development, besides the subcommissural organ, the ependyma lining the pontine flexure constitutes an additional Reissner's fiber-secreting gland named flexural organ. We have studied the secretion of the f...

In this paper, we intend to study the synthesis of the multibeam arrays. The synthesis implementation’s method for this type of arrays permits to approach the appropriated radiance’s diagram. An adaptive particle swarm optimization algorithm (APSO) is proposed to synthesis multibeam antenna arrays. The problem is formulated and solved by means of the proposed algorithm. The examples are simulat...
