the problem of propagation of plane wave including body and surface waves propagating in a transversely isotropic half-space with a depth-wise axis of material symmetry is investigated in details. using the advantage of representation of displacement fields in terms of two complete scalar potential functions, the coupled equations of motion are uncoupled and reduced to two independent equations...

Deterrence theory is the framework traditionally used to underpin road policing practices. However, there have been several developments in deterrence theory. This study uses an integrated approach and tests four hypotheses derived from classical theory, Stafford Warr’s reconceptualization informal sanctioning. Regression analysis of self-reported data a sample ( N = 623) Queensland’s drivers p...

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

This paper analyzes how subjective experiences of being punished affect subsequent offending behavior. The context of our study is the enforcement of speeding tickets through speeding radars in a suburb of Prague. Using unique data that cover anonymized individual driving and ticketing histories of more than 170,000 car owners over 15 months, we evaluate drivers’ responses to receiving a speedi...

Tracking and detecting of object is one of the most popular topics recently, which used for motion detection of various objects on a given video or images. To achieve the goal of intelligent navigation of a moving platform operating on the sidewalk, our goal is to build the software that is able to detect the pedestrians and predict their trajectories, during which process MOT (multiple object ...

in this paper, the coupled dispersive (2+1)-dimensional long wave equation is studied. the traveling wave hypothesis yields complexiton solutions. subsequently, the wave equation is studied with power law nonlinearity where the ansatz method is applied to yield solitary wave solutions. the constraint conditions for the existence of solitons naturally fall out of the derivation of the soliton so...

Today’s production processes are characterized by global supply chains, short lifecycles, and an increasing personalization of goods. To satisfy the demands for agility we must integrate the production with the logistics processes and knowledge about the underlying transportation services and infrastructure. This requires continuous monitoring and reacting to events. Service-oriented architectu...
