In this paper we propose a new message-passing algorithm for quadratic optimization. The design of the new algorithm is based on linear coordinate-descent between neighboring nodes. The updating messages are in a form of linear functions as compared to the min-sum algorithm of which the messages are in a form of quadratic functions. Therefore, the linear coordinate-descent (LiCD) algorithm has simpler...
This paper proposes a stratified approach for camera calibration using spheres. Previous works have exploited epipolar tangents to locate frontier points on spheres for estimating the epipolar geometry. It is shown in this paper that other than the frontier points, two additional point features can be obtained by considering the bitangent envelopes of a pair of spheres. A simple method for locating...
Because of its high dielectric strength, good partial discharge capability, low global warming potential (GWP), none ozone depletion potential (ODP) and nontoxicity, fluorocarbon gas is possible substitute for SF6, and can be used hopefully in electrical equipment, such as circuit breaker. In this paper, we calculate the pressure characteristic of circuit breaker using gas mixture containing fluorocarbon...
In a video surveillance network system constructed by multiple PTZ cameras, when the target access to one camera's FOV(field of vision) from another's, it is a key problem in this system to achieve reliable target relay tracking in a large and complex scene. This paper studies a method to determine multi-cameras' common relay area (RA) and FOV lines, presents a adaptive blocked rule of the tracking...

Past research has indicated that the effectiveness and efficiency of traffic control of signalized intersections strongly depend on the accurate calculation of saturation flow rate, particularly when demand approaches capacity. Minimal work has been done in the past on calibration of the parameters for saturation flow rate used in traffic control of signalized intersections. This paper discusses a...
Network design problem has originated in the practice of traffic engineering. Planning and designing road system has always been the most important task of traffic engineers. The objective of network design problem is to plan and design an improvement project for a road network systematically so that the total travel cost of the whole road system is minimized. Because of the complexity of the models,...
