The need for critical improvements to the North American surface transportation infrastructure vis-a-vis alleviation of congestion while enhancing public safety has led to new Intelligent Transportation Systems (ITS) infrastructure based on vehicle-to-vehicle (v2v) wireless communications. The allocation of 75 MHz in the 5.9 GHz band for DSRC (Dedicated Short Range Communications) may also enab...

Assumption of exchange rate overshooting has significant position in international macroeconomic discussion. This phenomenon is one of the abnormal behaviors of exchange rate that happen in short run. Dornbusch (1976) shows that because speed of equilibrium prices is slow relative to asset markets and commodity prices are sticky in the short run, However, over time, commodity prices will rise a...

In high-speed satellite-to-ground laser communications, it has been shown that the Markov-based erasure channel model is well suited for the downlink experiment results. In that model, since the average erasure rate is relatively high, a low-rate error correction code is needed. In this paper, we focus on the application of low rate systematic Luby transform (SLT) code and show that the perform...

one very decisive factor in students’ academic destiny is the result they get at final term examinations. because of its importance, both students and teachers are curiously anxious about them. as normally it is the case, these final term tests are prepared hurriedly in short time by teachers which result in students’ dissatisfaction, complaining on how the test was different from their expecta...

A system was developed to efficiently schedule aircraft into congested resources over long ranges and present that schedule as a decision support system. The scheduling system consists of a distributed network of independent schedulers, loosely coupled by sharing capacity information. This loose coupling insulates the schedules from uncertainty in long-distance estimations of arrival times, whi...

background: as the use of mobile phones is increasing, public concern about the harmful effects of radiation emitted by these devices is also growing. in addition, protection questions and biological effects are among growing concerns which have remained largely unanswered. stem cells are useful models to assess the effects of radiofrequency electromagnetic fields (rf-emf) on other cell lines. ...
