Variety of facial pose and expression will affect result of face recognition. Traditional methods analyze facial pose and expression through every pixel of image, on the contrary, the paper analyzes pose and expression through geometric relationship among images. The paper uses locally linear embedding (LLE) which computes low dimensional, neighborhood preserving embedding of high dimensional data...
Based on the geometry features of lunar terrain, this paper treats lunar terrain reconstruction as a surface reconstruction problem. We define an energy functional model consisting of local energy term and smooth energy term for lunar terrain reconstruction. The solution to minimize the functional (by partial differential equations) is defined as the optimal surface. In the smooth energy term, we...
According to the objective weigh provided by fuzzy iteration methodology, the paper presents the concept of weight tradeoff coefficient, combining subjective and objective weight together. Since the method takes into account, in the meantime, the objective intent of decision-maker and the natural property of alternative, the weight and relative member-ship degree are directly obtained from the recommended...
Cold-starting problem of recommender system has attracted much attention. In the case of cold-starting, the extreme sparsity of ratings would induce poor performance of traditional recommendation algorithms. This paper presents a new algorithm to deal with the issue of cold-starting by taking the preference of user's ratings into consideration. After normalizing historical rating matrix, two-stage...
Procedure and method for the design and development of safety instrumented system (SIS) in process industries has been presented. A technique of the system hazard analysis and initial risk assessment used for safety instrumented function (SIF) determination and assignment has been introduced. Procedure and methods of safety integrity level (SIL) selection are investigated in detail. Plan and engineering...
This paper presents a navigation simulation system on lunar rover. With virtual reality technology, this system serves to verify the kinematics model and the validity of the planning-path for navigating lunar rover. Because the lunar terrain can not be treated as the 2D surface, the kinematics modeling of lunar rover unlike ordinary mobile robots needs to contain the information about terrain. This...
In the paper, we present a vision based algorithm used to guide the unmanned ground vehicles (UGV) for autonomous stairways climbing and implement it on UGV successfully. The reliability of guiding UGV to climb stairs requires evaluating two offset parameters: the position of vehicle on stairs and the orientation angle to stairs. The intention of our algorithm is to estimate these two parameters through...
Cluster tools are fundamental equipments in over-8-inch wafer manufacturing. Due to the toolspsila unique physical structure and particular semiconductor manufacturing demands, the scheduling of cluster tools is more complex than normal Job-Shop problems. This paper proposes a scheduling algorithm for dual-armed cluster tools based on Heuristic Search. We mainly examine the scheduling technique under...
This paper presents a Digital to Analog Converter (DAC) suitable for video applications. This DAC can generally simplify conventional DAC circuits. The 8-bit DAC only requires twelve switches and twelve resistors to achieve the goal of high speed and low power applications. This DAC is implemented by TSMC 0.18 mum process technology. The simulation results of our work with integral non-linearity (INL)...
The knowledge and expertise of researchers and professors is the major asset that universities hold. In order to make use of this asset, it is necessary to share expertise between staff as well as transfer expertise to industry. Expertise matching - locating experts with the specific expertise is receiving more and more attention since it facilitates people connection to each other. This paper proposes...

It makes use of methods of image and graphics processing and integrates properties of ultrasonic image. Firstly, an available loss technique is used to...
A novel method for the stabilization of a class of networked control system (NCS) with communication delays has been presented. By constructing a sliding manifold that can compensates delay, a sliding mode variable structure control scheme that has exponentially approaching characteristic is proposed. System stability under the control law is then analyzed, and maximum allowed network-induced delay...

The report analyzes all the available experimental data from three laboratories on the entropy-energy relation of two different strongly interacting trapped Fermi gases, and compare this directly with a single universal theoretical prediction. A diagrammatic approach based on functional path-integrals is used together with the local density approximation to treat the inhomogeneous trap. Below the...
To establish a parallel fusion approach of processing high dimensional information, the model and criterion of multi-sensor fuzzy stochastic data fusion were presented. In order to design genetic algorithm fusion ( the fusion parameter coding ) initial population and fitness function establishing, and fuzzy logic controller designing for genetic operations and probability choosing were complete d...
In complex multi-agent fusion systems resource conflicts are very likely to occur. We propose an algorithm that determines the optimal sensing resource to fusion task assignment, based on the entropy change criterion. By exploiting the Bayesian network framework and the structure of our agent network the algorithm operates in a distributed manner by combining descriptions of local fusion models in...
In this paper a point rendering system for ray tracing is presented. An oriented planar patch which passes a surface point is used to approximate the vicinity of that point. This paper defines a new point attribute for the purpose of efficiently locating the intersection between incoming ray and surface points. Accordingly, an algorithm of intersecting a ray with point geometry is proposed. The algorithm...
