Extensive empirical experience suggests that traditional forecasting approaches are subject to more or less severe model misspecifications which affect true (out-of-sample) oneas well as multi-step ahead forecasting performances. The main problems are due to non-stationarity and non-Gaussianity. In order to overcome these difficulties, we propose a prototypical design derived from a traditional...

The Small Target Visibility model used in road lighting design is based on a strong simplification of the driving task. To specify the driver’s visibility needs in a way consistent with state-of-the-art lighting engineering practice, a field experiment was designed in order to investigate target detection performances, comparing driver and passenger status conditions. Sixteen target visibility ...

There is a great interest to apply BSS methods in mechanical system signal processing for monitoring or diagnosis purpose. Actually, we show that BSS allows to recover the vibratory information issued from a single rotating machine working in a noisy environment by freeing the sensor signal from the contribution of other working machines. In that way, BSS can be used as a pre-processing step to...

the purpose of this study is assessing the effects of competitive strategy and technological innovation on export performance based on competitive environment in non metal mineral industry of iran. in this paper, available approaches in the scope of determinants of ep are identified consist of contingency view, relational and resource based view. in this study, we examine relationship between t...

I review the characteristics of planetary systems accessible to imaging. I show that, beyond the basic angular resolution and dynamics performances of an optical “architecture”, other performances such as photometric precision, spectral range or timing are necessary to access some physical characteristics of the planets.

The employee-employer relationship is an intricate one. In an industry, the employers expect to achieve performances in quality and production in order to earn profit, on the other side employees need good pay and all possible allowances and best advantages than any other industry. Our main objective of this paper is to analyze the relationship between employee and employer in workplace and dis...

Wellbore stability are influenced by many complex factors, and there is no commonly used prediction method on wellbore stability until now. Use of an efficient decision making technique which can take into account several criteria in such conditions is necessary. Referring to traditional wellbore stability analyzing methods, the fuzzy comprehensive evaluation method of predicting wellbore stabi...

The excessive vibration caused by crowds walking across footbridges has attracted great public concerns in the past few decades. This paper presents, from considering the dynamic characteristics of the bipedal crowd model, a new stability limit criterion based on the bipedal excitation model. The stability limit can be used to estimate the upper boundary of crowd size. In addition, the dynamic ...

This paper presents an introduction to interactive multimedia performance, discusses its various components and focuses on preservation issues. As interactive multimedia performance is becoming popular in the performing arts communities, like other types of performance, there is the need to preserve related information and components of a performance for future study, analysis and recreation. O...

in today’s competitive world employees with engagement can interact with their job and have desirable job performance. since improvement of employees’ job performance is the key of efficiency in all levels of organization, investigation of variables leading to the improvement of job performance is of great importance. thus the purpose of the present research is to analyze the effect of employee...
