The AdS/CFT correspondence suggests that the Wilson loop of the large N gauge theory with N = 4 supersymmetry in 4 dimensions is described by a minimal surface in AdS5 × S5. We examine various aspects of this proposal, comparing gauge theory expectations with computations of minimal surfaces. There is a distinguished class of loops, which we call BPS loops, whose expectation values are free fro...

HEV’s energy control strategy cannot be regulated perfectly according to the variable working condition, because the driving resistance is difficult to measure and calculate during the driving process. By taking parallel-serial HEV which power coupling mechanism is planet-gear as research object, analyzed planet-gear power coupling mechanism’s dynamics characteristic and efficiency characterist...

In order to generate behavior that can be validated, a cognitive task model needs to be implemented in software. This paper first introduces a cognitive task model based on a BDI framework and then focuses on the translation of that model into the ACT-R theory and software. Problems encountered during this translation process are described and further implications are discussed. It is found tha...

This study was designed to determine the effect of contextualized advisement and competition on transfer of mathematics skills in a computer-based simulation game in which participants helped their “aunt and uncle” fix up a house. Contextualized advisement referred to whether the participant had access to video-based advisement delivered by the aunt and uncle about how to solve the problem, and...

A number of emerging applications of data management technology involve the monitoring and querying of large quantities of continuous variables, e.g., the positions of mobile service users, termed moving objects. In such applications, large quantities of state samples obtained via sensors are streamed to a database. Indexes for moving objects must support queries efficiently, but must also supp...
