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...

In this paper, artificial neural networks (ANN) are proposed to classify and establish zoning faults (single-phase, bi-phase and tri-phase short circuits) in primary distribution systems. The proposed classification and zoning models are oriented toward the stochastic tracking of failures via emergency brigades. This work, instead of training a big ANN model, proposes to decompose the problem i...

the takmeh-dash region comprises a wide variety of igneous bodies that have been developed from early to late neogen. the granitic rocks and related aplite apophyses have been developed along fault-dominated structures which defines a well pronounced mineralized zone. according to isotopic and fluid inclusion studies, most of the quartz-pyrite units are solution-related with some traces of cu, ...

Many health studies use aggregate data such as the means or totals for areal units or zones when individual level data are not available. An ecological analysis using these data typically produces estimates that differ from those obtained using the corresponding individual level analysis. This is due to the modifiable area unit problem (MAUP) whereby the results of the analysis depend on the sc...

In the field of Optical Character Recognition (OCR), zoning is used to extract topological information from patterns. In this paper zoning is considered as the result of an optimisation problem and a new technique is presented for automatic zoning. More precisely, local analysis of feature distribution based on Shannon’s entropy estimation is performed to determine “core” zones of patterns. An ...

Corrosion in general is a complex interaction between water and metal surfaces and materials in which the water is stored or transported. Water quality monitoring in terms of corrosion and scaling is crucial, and a key element of preventive maintenance, given the economic and health hurts caused by corrosion and scaling in water utilities. The aim of this study is to determine the best model fo...

Inclusionary zoning (IZ) is an affordable housing tool that links the production of affordable housing to the production of market-rate housing. IZ policies either require or encourage new residential developments to make a certain percentage of the housing units affordable to lowor moderateincome residents. In exchange, many IZ programs provide cost offsets to developers, such as density bonus...

Considerable prior analysis has gone into the study of zoning restrictions on locational choice and on fiscal burdens, but none addresses the level and distribution of public goods provided under fiscal zoning. Our analysis emphasizes the interplay between land use restrictions and public good provision, focusing on schooling outcomes. We extend existing general equilibrium models of location a...

Protected areas worldwide are facing increasing pressures to co-manage human development and biodiversity conservation. One strategy for managing multiple uses within and around protected areas is zoning, an approach in which spatial boundaries are drawn to distinguish areas with varying degrees of allowable human impacts. However, zoning designations are rarely evaluated for their efficacy usi...
