The present research aims to evaluate impacts of crude oil price return index, Bloomberg Petroleum Index and Bloomberg energy index on stock market returns of 121 companies listed in Tehran stock exchange in a 10 years' period from early 2006 to April 2016. First, explanatory variables were aligned with petroleum products index mostly due to application of dollar data. Subsequently, to check va...

the aim of this paper is to assess the adaptation of iran’s energy policies to the kyoto protocol. in the past two decades, iran has experienced a considerable increase in greenhouse gas (ghg) emissions; in 2013 it was the world’s ninth largest emitter. although adapting to this protocol in iran’s energy and climate policies seems vital and urgent, its recent status is not promising. this paper...

The effect of Ta alloying on the structure, mechanical properties and scratching behavior Ti-Al-N-based coatings deposited Ti substrates by reactive direct-current magnetron sputtering is studied. It was found that increasing content in Ti1-x-yAlxTayN from y = 0 to 0.65 led a decrease hardness Young’s modulus but an increase hardness-to-modulus ratio. This resulted reduction load-bearing capaci...

ß-Cyclodextrin (ß-CD) solubilizes stickies from deinked pulp, commercial adhesive formulations, or magazine inserts, which demonstrates its potential as a washing aid. A new test to simulate coater scratches is described; it involves scraping the test paper sample across the surface of a thin layer chromatography plate and measuring the degree of scratching on the plate. Scratching was signific...

The acoustic emission (AE) measured during single diamond scratching of granite can provide valuable information about the structural composition and sawability of natural stone material. As described by Prof. Dr.-Ing. R. Clausen*, Dr, C.Y. Wang** and Dr,-Ing, M. Meding***, scratching tests are shown to i ndicate a direct relationship between the characteristics of AE generated by scoring, the ...

in this paper, downlink resource allocation for a sparse code multiple access (scma) based heterogeneous  cellular networks (hcn) is investigated. the main aim of this paper is to obtain joint power allocation and codebook assignment to achieve the least total system transmit power. in this regard, the proposed objective function is formulated as total transmit power subject to users minimum ra...
