Crowd sourcing systems like Yahoo! Answers, Amazon Mechanical Turk, and Google Helpouts, etc., have seen an increasing prevalence in the past few years. The participation of users, high quality solutions, and a fair rating system are critical to the revenue of a crowd sourcing system. In this paper, we design a class of simple but effective incentive mechanisms to attract users participating, and...
Splitting of an orthogonal polyhedron is an essential operation in many orthogonal polyhedron related problems. This paper proposes an algorithm for splitting an orthogonal polyhedron with an orthogonal polyplane. There are four major steps of this algorithm: 1) sort the vertices of the orthogonal polyhedron in ABC-sorted order; 2) calculate the vertices at the intersection between the orthogonal...
LGA sockets are becoming the leading technology to connect the micro-processors with the system boards of desktop or server computers. It is critical to understand the mechanical behavior of a socket to predict its required enabling load and reliability to certain confidence at the design phase. FEA has been used to achieve this goal at both component and system levels. This paper presents a sensitivity...
