Recent studies of convenience store crime have focused on robberies, but gasoline thefts are a troublesome and often overlooked public policy problem that drain valuable police resources. An analysis of calls for service from 38 convenience stores in Austin, TX reveals that gasoline drive-qffs account for 48% of all convenience store calls. This paper ties the environmental characteristics and ...

An important motivation for software testing is to increase con dence that the software no longer contains faults. In this paper we explain a technique for using fewer tests to gain an equivalent con dence in software. Our techniques complement random black box testing. To be able to use fewer tests and gain equivalent con dence, we must either (1) isolate and remove software characteristics th...

This experimental study employed a 2 2 2 factorial design to investigate the effects of type of instruction (procedural module, attitudinal module), deictic gesture (presence, absence), and facial expression (presence, absence) on student perception of pedagogical agent persona, attitude toward the content, and learning. The interaction effect between type of instruction and agent nonverbal beh...

In designing for ship production, the production method should be considered and it’s possible to reduce the manufacturing cost in designing procedure. A review of background of ship design that had minimized production costs, shows the principles and problems of these methods. Modern designing methods for manufacturing, considers hydrodynamic efficiency and less manufacturing cost. Quant...

in this paper, we proposed a novel structure for designing all optical filter based on photonic crystal structure. in designing the proposed filter, we simply employed a point defect localized between input and output waveguides as wavelength selecting part of the filter. the initial form of this filter is capable of selecting optical waves at =1560 nm, the transmission efficiency of the filte...
