in reality, most structures involved in geotechnical engineering are three dimensional in nature, and although in many, plane strain or axisymmetric approximations are reasonable, there are some, for which 3-d treatment is required. the quantity of data, and the size of the various vectors and matrices involved in such analysis, increase dramatically. this has sever implications for computer r...
This study examines the features and determinants of Portuguese intra-industry trade (IIT) during the period 1995-2003. We separate horizontal IIT from vertical III using data at the five-digit level. Based on Falvey and Kierzkowski (1987) and Flam and Helpman (1987) theoretical models and on Greenaway, Hine and Milner(1994), Hummels and Levinshon (1995) empirical studies, we use a static and d...
Joint IterativeTx/Rx MMSE-FDE and ISICancellation for Single-Carrier Hybrid ARQ with Chase Combining
We propose a joint iterative transmit/receive (Tx/Rx) minimum mean square error (MMSE) frequency-domain equalization (FDE) and intersymbol interference cancellation (ISIC) suitable for single-carrier (SC) hybrid automatic repeat request (HARQ) with chase combining (CC). In the proposed scheme, a one-tap transmit MMSE-FDE and an iterative one-tap receive MMSE-FDE and ISIC are employed. Every tim...
investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
background: describing trend in tuberculosis (tb) over time can play an important role to assess the disease control strategies and predict the future morbidity and mortality. this study aimed to determine the incidence trend of smear‑positive pulmonary tuberculosis (sppt) in sub‑age and sex groups during the years of 1995–2012. methods: this retrospective cohort study was performed in 2015 by ...
sange siyah dam is located two kilometers down the kabod khani village. the environ of ghorrve city in kurdestan province. this is an clay core dam. in this dam instrumentation is performed in three section and consist of electrical piezometers, total pressure cells, settlement cells and so on. the main objective of instrumentation is to control the behavior of dam body and foundation, end else...
abstract there is not much sources about ancient carnival and ceremonies , but some information can be gain from documents . as a matter of fact the ceremonies were a part of zarartiyan principles which zartosht had taken them to his religion . it should be mentioned that the oldest ceremonies are about poster and agriculture principles this seasonal ceremonies were very important for agri...

Based on the recent literature of heterogeneous firms, productive firms self select themselves into foreign markets. In this framework, there is a productivity rise prior to exporting. On the other words, different export performance across firms is linked to their heterogeneity. Â The main purpose of the present paper is to examine the so-called hypothesis of heterogeneous firm in Iran. For ...
the main objective of this paper is to evaluate the effect of r&d on profitability of high -tech industries with new evidence from the iranian industries carrying four- digit codes. the structure- conduct- performance (scp) paradigm, which is relatively well known in industrial economics and in organization management, provides the theoretical construct that guides our empirical model formu...
