background: cardiovascular disease (cvd) is one of the leading causes of death in the world. one of its most insidious forms is coronary heart disease (chd) which decreases patient's quality of life. research indicates that psychological factors are interrelated with coronary heart disease patients' quality of life. in the present study, the role of type d personality and emotional intelligence...

The analysis of macroeconomic variables for current situation in Iran indicates a Conundrum. Solving this puzzle is vital for Central Bank of Iran in order to choose an appropriate approach for monetary policy and banking supervision. Increase in liquidity growth rate, significant decrease of inflation rate and interest rate rigidity are the three sides of this puzzle. This study designs an inn...

background: pelvic ring injuries and sacroiliac dislocations have significant impacts on patient’s quality of life. several techniques have been described for posterior pelvic fixation. the current study has been designed to evaluate the spinopelvic method of fixation for sacroiliac fractures and fracture-dislocations.   methods: between january 2006 and december 2014, 14 patients with sacroili...

The speech enhancement techniques are often employed to improve the quality and intelligibility of the noisy speech signals. This paper discusses a novel technique for speech enhancement which is based on Singular Value Decomposition. This implementation utilizes a Genetic Algorithm based optimization method for reducing the effects of environmental noises from the singular vectors as well as t...

QoE analysis of media services over IP networks (e.g., VoIP, IPTV, OTT, etc.) is a complex task, since it is based on the subjective human opinion. The subjective assessment requires a large number of volunteers to periodically provide feedback about the perceived quality of a service. Accordingly, there is a requirement for an objective alternative to the inherently subjective, perception-base...

SUMMARY This paper proposes an adaptive transmission scheme of MIMO systems to provide different bit error rate and transmission rate for multimedia traffic. The adaptive transmission scheme allocates antennas, rate and power jointly according to the feedback information to satisfy the diverse QoS requirements of the multimedia traffic. Furthermore, an efficient search algorithm with low comple...

Process monitoring of multivariate quality attributes is important in many industrial applications, in which rich historical data are often available thanks to modern sensing technologies. While multivariate statistical process control (SPC) has been receiving increasing attention, existing methods are often inadequate as they either cannot deliver satisfactory detection performance or cannot c...

This paper discusses a new approach to QoS routing, introducing the notion of algorithm resilience (i.e., its capability to adapt to network and load modifications) as performance index of the algorithm itself, for a given network topology, load and traffic pattern. The new approach can be summarized as Network Graph Reduction, i.e., a modification of the graph describing the network before the...

This paper discusses a new approach to QoS routing, introducing the notion of algorithm resilience (i.e., its capability to adapt to network and load modifications) as performance index of the algorithm itself. The new approach can be summarized as Network Graph Reduction, i.e., a modification of the graph describing the network before the routing path is computed, in order to exclude from the ...

purpose: to evaluate the health-related quality of life (hrqol) among strabismus patient. methods: one hundred and twenty-two strabismic patients ≥ 14 years who scheduled for surgery were selected non-randomly. the patients completed the adult strabismus 20 (as-20) and sf 36 questionnaires. measurements were performed preoperatively and 3 and 6 months postoperatively. changes in psychosocial an...
