Software free trial is a common practice that has both positive and negative effects. On the one hand, it helps firms to exploit the positive network externalities by building up the total user base; on the other hand, it cannibalizes partial demand for the commercial software. The objective of my dissertation is to determine the conditions under which the firms should introduce the free trial ...

In this paper, a new microscopic traffic model based on forward and rearward driver response is proposed. Driver characterized using the distance time headways. Existing models such as Intelligent (ID) characterize flow constant acceleration exponent. This exponent reflects uniform behaviour during different conditions which unrealistic. slow with large headway quick short headway. Conversely, ...

M odel-based test automation has helped reduce cost, provide early identification of requirements defects, and improve test coverage [1, 2, 3, 4, 5, 6]. Industry use of model-based test automation has provided insight into practical methods that use interface driven analysis with requirements mod-eling to support automated test generation. However, the term interface is used loosely in this art...

One of the most efficient lighting technology is based on light-emitting diodes (LEDs). Common LED drivers with AC-input (50-60Hz) usually require a bulk electrolytic capacitor to decrease low-frequency ripple in the output. However, the critical element that limits the lifespan of the LED driver is the electrolytic capacitor. An isolated off-line LED driver is proposed in this paper, in which ...

Driver profiling has a major impact on traffic safety, fuel consumption and gas emission. LSTM CNN based neural network models were developed to classify assess bus driver behavior characterized by deceleration, engine speed pedaling, corner turn lane change attempts. Deceleration, test scenarios performed concrete paved track while changing tests conducted commercial asphalt highway. Despite t...
