fault location in power distribution networks using matching algorithm

چکیده رساله/پایان نامه : تاکنون روش‏های متعددی در ارتباط با مکان یابی خطا در شبکه انتقال ارائه شده است. استفاده مستقیم از این روش‏ها در شبکه توزیع به دلایلی همچون وجود انشعاب‏های متعدد، غیر یکنواختی فیدرها (خطوط کابلی، خطوط هوایی، سطح مقطع متفاوت انشعاب ها و تنه اصلی فیدر)، نامتعادلی (عدم جابجا شدگی خطوط، بارهای تک‏فاز و سه فاز)، ثابت نبودن بار و اندازه گیری مقادیر ولتاژ و جریان فقط در ابتدای...

Roles of Fluctuations in Pulsed Neural Networks

Concerning the fluctuation which is observed in biological sensory systems and cortical neuronal networks, the roles of fluctuations in pulsed neural networks are investigated. As a model of a single neuron, the FitzHugh-Nagumo model is used, and two kinds of couplings of neurons are considered, namely, the electrical coupling which is often observed in sensory systems, and the chemical couplin...

Roles of hubs in Boolean networks

We examined the effects of inhomogeneity on the dynamics and structural properties using Boolean networks. Two different power-law rank outdegree distributions were embedded to determine the role of hubs. The degree of randomness and coherence of the binary sequence in the networks were measured by entropy and mutual information, depending on the number of outdegrees and types of Boolean functi...

Persistent Roles in Online Social Networks

Abstract. Users in online social networks often have very different structural positions which may be attributed to a latent factor: roles. In this paper, we analyze dynamic networks from two datasets (Facebook and Scratch) to find roles which define users’ structural positions. Each dynamic network is partitioned into snapshots and we independently find roles for each network snapshot. We pres...
