This paper deals with the problem of obtaining the optimum path for a vehicle to its destination. We propose architecture based on which vehicles are able to find the best path toward their destination using real-time traffic information thus, travel time is reduced and roads traffic capacity is increased. Pervious system, aiming at the same goal, use traffic flow prediction thus their information is not real-time and even precise. Moreover, some systems use GPS data but due to coverage limitations (in dense city environments, tunnels) permanent accessibility may not be provided. In this paper, thus, we propose architecture for such a system based on communication between vehicles and road side infrastructure. We first propose a scheme for Road Side Unit (RSU) placement so that the maximum coverage with minimum numbers of RSUs is achieved. Then an algorithm is proposed for information gathering though which real-time traffic information is circulated between all RSUs. Finally this information is used for navigation of vehicles toward their destination during city trips. Results of simulation study conducted by NTCUns shows the good performance of the proposed idea. Manuscript profile

Proccess of quality of service (Qos) evaluation and optimization for mobile telecommunication networks is consisted of daily collection of key performance indicators (KPI) reports, determination and fixing of defects, and network testing to ensure the omission of the defects. Drive test is common approach of testing which is time-consuming and expensive dut to necessity for expertists and equipment. To overcome these limitations, this paper proposes a new software-based testing method using OPTIMA software. Performace of this proposed methed together with drive test approach have been studied and evaluated for the 70 BTS sites of Kerman GSM network as the statistical society. The results demonstrate that the proposed method provides performance similar to that of drive test for measurement of defect fixing. However, this software method not only removes the dependency to expertists and equipment, but also reduces the testing time about one-third comparied to the drive test. Manuscript profile

Today, with the advent of technology businesses and the formation of a knowledge-based economy, the importance of technology valuation has increased. A wide variety of factors in the form of a causal system will affect the issue of technology valuation. However, a significant portion of the feedback can appear over a period of time and with a not necessarily linear behavior. Therefore, the analysis of a set of factors affecting the category of technology valuation in the form of a systemic and at the same time dynamic view can affect the efficiency and effectiveness of relevant decisions. Therefore, in the present study, due to the dynamic nature of the decision-making problem and faced with various evaluation criteria in the process of analysis and selection of technology evaluation strategies, a combined analysis method based on the dynamic systems approach and multi-criteria decision-making is presented. The proposed model has been implemented to evaluate the technology of the Teflon container manufacturing industry as a case study. The results indicate the efficiency of the proposed dynamic model in analyzing the relationships between variables that have a direct and indirect impact on the issue of technology valuation. In addition, using the TOPSIS and analytical hierarchical process methods, strategies based on the simulation results are evaluated and finally prioritized. Manuscript profile

In this study, we have used the total capital market index (TEDPIX) as an index of the real sector of the economy and the index of banks and credit financial institutions as an index that explains the developments of the banking system. Also, oil revenues, exchange rate uncertainty, tax revenues, liquidity, nominal interest rates, inflation uncertainty and GDP have been used as macroeconomic variables in the research period (1370-1396). To estimate the systemic risk of the banking system, the quarterly data of the banks' index is used and the value at risk of the return of the seasonal data of the index is estimated using an exponential GARCH model. In order to model the interaction of macroeconomic variables and systemic risk of the banking system, an unrestricted vector autoregression (VAR) model was estimated and then using instantaneous impact functions and based on Chulsky analysis, systemic risk response to other variables was investigated and analyzed. In order to identify the channels of impact of economic shocks on the systemic risk of the banking system, based on the structures of the Iranian economy, a structural vector autoregression (SVAR) model was specified and then the instantaneous impact functions were extracted and the effect of macro variable shocks on the systemic risk of the banking system was investigated. Also, the effect of systemic risk of the banking system on macroeconomic variables was investigated and analyzed using instantaneous impact functions. Finally, the interaction model of macroeconomic variables and systemic risk of the banking system was approved using the vector autoregressive model. Manuscript profile
