the successful key of trading in the forex market is the selection of correct exchange in proper time based on an exact prediction of future exchange rate. foreign exchange rates are affected by many correlated economic, political and even psychological factors. therefore, in order to achieve a profitable trade these factors should be considered. the application of intelligent techniques for fo...

the aim of this research is to investigate the relationship between leader – member exchange and organizational citizenship behavior, and considering the mediating role of psychological empowerment and organizational commitment. the sample consisted of 250 employees of marun oil and gas producing company who were selected by simple random sampling method. the instruments which used in this rese...

[1] High‐speed video images of eight branches of a lightning stepped leader recorded at a frame rate of 300 kiloframes per second (kfps) (3.33 ms exposure) are analyzed, representing the fastest published frame rate measurements of stepped leader stepping by about 1 order of magnitude and the first observations of space stems/leaders associated with stepped leaders. Sixteen occurrences of space...

Scanning arrays of antisense DNA oligonucleotides provide a novel and systematic means to study structural features within an RNA molecule. We used this approach to probe the structure of the untranslated leader of the human immunodeficiency virus type 1 (HIV-1) RNA genome. This 335 nt RNA encodes multiple important replication signals and adopts two mutually exclusive conformations. The poly(A...

Abstract Limited by rigid instruments, traditional open curettage of bone cysts requires large incisions and the removal substantial amounts healthy tissue to approach lesion. This causes a lengthy recovery period with an increased risk for complications. While other less invasive methods have been suggested, none accepted as standard treatment modalities, many them not applied beyond academic ...

We consider the problem of leader election in asynchronous oriented N-node complete networks. We present a leader election algorithm with O(N) message and O(log log N) time complexity. The message complexity is optimal and the time complexity is the best possible under the assumption of message optimality. The best previous leader election algorithm for asynchronous oriented complete networks b...

Autonomous ground vehicles have been designed for the purpose of that relies on ranging and bearing information received from forward looking camera on the Formation control . A visual guidance control algorithm is designed where real time image processing is used to provide feedback signals. The vision subsystem and control subsystem work in parallel to accomplish formation control. A proporti...

This paper studies the effect of the three most commonly used demand functions, i.e. additive, multiplicative and iso-elastic demand, on the investment decisions of two competitive firms. We show that the relative investment decision of the two firms can be very sensitive to the choice of a specific demand function. We find that the use of the multiplicative demand function results in a market ...
