The present study investigates the prevalence of parallel capital market revolts on stock exchange trading industries. In this study, the overflow of stock exchange industries has been measured separately for export and import-oriented parallel markets of currency and gold. In this regard, the autoregressive vector analysis (VAR) method and the autoregressive model conditional on the heterogeneity of multivariate generalized variances (MGARCH) have been used. The data of this research have been collected and tested using Eviews software from the beginning of September 2015 to the end of August 2016. The method of the present study is based on the classification of research based on the method, nature and direction of descriptive, applied and post-event, respectively, and is considered as a correlation in terms of type.The results of this study confirm the relationship between the effect of the overflow of export-oriented stock exchange industries from the parallel foreign exchange market; However, the research results of this overflow have not been confirmed by the parallel gold market. In this regard, the effect of the overflow of import-oriented industries from the parallel markets of currency and gold has not been confirmed. The side findings of the present study also show that there was a positive and two-way relationship between the two markets of currency and gold in the period under study. Manuscript profile

Nowadays, due to advances in technology and information technology fast processing of data is a growing need. Residue Number System is an unconventional and non-Weighted System that parallel computing on remainders of dividing number on several modules is performed. The computations are performed cause to increase the speed of computing and reduce the power consumption. One of the problems in this system is published overflow that due to the modular operations and nature of non-weighting numbers. In order to solve this problem in many cases using to binary number system converter and convert the number to the weighted numbers to comparison and overflow detection is necessary. In this article, the novel methods to improve the detection of overflow in moduli set {2n-1, 2n, 2n+1} without doing a full comparison and need the reverse convert process. Also The proposed method is compared with previous approaches, in addition to fewer hardware components, the delay is very low. Manuscript profile

For more accurate measurement of the water flow, it has been always attempted to design structures with least errors and highest accuracy. Nowadays, the use of artificial neural networks (ANN) models has been rapidly grew mainly due to the fact that these models are not confined to the physical parameters. Artificial neural networks are based on use of embedded knowledge between input and output variables of a problem, regardless of physical aspects and these networks are able to extract inherent relation of the input and output and they can generalize the obtained relation to other situations and cases. In the present research, the information related to the overflow of Marun Storage Dam was adopted. The input parameters of ANN model are as follows: day, month, water surface elevation, water sharing percent and output parameters overflow discharge of storage dam. The models employed in artificial neural networks include FF, JEN, MLP and RBF. Moreover, the genetic algorithm (GA Manuscript profile

In recent decades, stepped spillways have been a significant role in this case.. This research is based on The flow energy calculated on these edged steps and simple steps in nappe flow and skimming flow regimes. Difference in height, width and edge slopes will determine the effects of each of these parameters on energy dissipation ratio And then the analysis of sixteen model with different geometries were conducted by Gambit and Fluent software for two discharges ٣/٦ lit/s (nappe flow) and ٢٥ litr/s (skimming flow) by the total of ٣٢ models. And with regard to the results achieved, the influence of the edge for nappe flow has been regarded according to Chamani and Rajaratnani equations. With regard to the results, it is suggested that the existence of the edge at the step end can be enhanced the energy dissipation ratio along the stepped chute. Of course the ratio of this effect in flow and skimming regimes are not the same and these effects are decreased by increasing of discharge. Manuscript profile

Hydraulic structures such as stilling basins, mainly are used for the purpose of energy dissipation in the lower zone of overflows, chute and diversion dams, in order to control hydraulic jump. In this research, the rate and effect of the jump is determined by laboratory tests. In these experiments, the sharp roughness of the bed of basin and also the change in the slope of the basin( structure ) from 0 to 0.3 percent were tested and parameters such as flow rate, initial depth, secondary depth, jump length of water surface profile, water head on overflow crown and water head prior to overflow were accurately measured. The analysis of data showed that the sharp roughness can effectively reduce the length of jump to to 35.5%. For sharp shape roughness, with an increase in the landing rate, the ratio y2 / y1 increases by an average of 6.5%. For a Froude number with a sharp roughness setting, the Lj / y2 ratio decreases by an average of 1.2%. Manuscript profile

In recent years, Information and Communications Technology has the greatest impact on different aspects of human's life including effect of this technology on all economic sectors. In particular, ICT has increased Total Factor Productivity in many countries of the world especially developed countries from the second half of the 0991s. ICT capital has characteristics of knowledge commodity. Hence, it is able both through capital deepening and by its overflowing effect to affect productivity. This paper investigates ICT impact on TFP using Panel Data Method for the sample of selected developing and developed countries within the time period 3112-3112. Results of this study indicate that ICT internal investment and ICT external capital or the very ICT overflow, both, have positive and significant effect on TFP both in the sample of all the selected developing countries and in the sample of developed countries. In addition, effect of human capital on TFP in both samples of developed countries and selected developing countries was found positive. Manuscript profile

During financial stress, the impact of financial stress shocks on economic activity may differ from what is usually observed at normal times. Therefore, it is appropriate to consider the effects of financial stress on economic activity and inflation during the period of financial instability. In this paper, hence, the effect of the deterioration of financial conditions of the Iranian economy on macroeconomic variables between 2012  and 2017 has been investigated. For this purpose, in this research, we intend to study the impact of the fluctuations of the financial stress index on inflation, interest rates, liquidity, and industry index by developing the financial stress index using representatives from different markets. Therefore, using the GARCH two-variable BEKK model and also the VAR model, the effects of shocks and fluctuations between them were tested and then the relationship between them was investigated by Granger's causality test. The results indicate that there is a two-way relationship between the financial stress index and inflation, interest rate, and liquidity, but in examining the causality between the financial stress index and the industry index, the results of the causality test indicate that the industry index itself, in the long run, triggers changes in the financial stress index, but the financial stress index has no effect on the industry index.
