In this paper we review the basic issues of quantum cosmological models. We explore the Wheeler-DeWitt equation in different contexts but from a dimensional point of view. We end by presenting the Wheeler-DeWitt equation in the case of considering all the constants varying. The quantum potential is obtained and the tunneling probability is studied.

The Burrows-Wheeler transform is a block-sorting algorithm which has been shown empirically to be useful in compressing text data. In this paper we study the output distribution of the transform for i.i.d. sources, tree sources and stationary ergodic sources. We can also give analytic bounds on the performance of some universal compression schemes which use the Burrows-Wheeler transform.

INTRODUCTION The risk of collision between pedestrians and powered two-wheelers is poorly understood today. The objective of this research is to determine the risk for powered two-wheeler drivers of hitting and injuring a pedestrian per kilometer driven in towns and to compare this risk with that run by four-wheeled vehicle drivers. METHOD Using the bodily injury accidents recorded by the pol...

Indian villages, towns and cities have high air and noise pollution caused by transport vehicles, especially petrol/dieselpowered three-wheelers. Conventional Internal Combustion Engine (ICE) driven 3 and 4 wheelers are against environment friendly and those are having very less efficiency when compared to EVs (Electric Vehicles). This paper details the overall construction and development of a...
