	Abstract:Two methods can be used to measure water level. One is creating a water-level measuring post, then read it by human each time. Another one is using sensor to derive the analog water level, then transform it to digital value. There are many different sensors for water level measuring, such as float model, pressure model, supersonic model, etc. This paper provides a method that derives the image of water level by camera firstly, then by employing the methodology of image preprocessing, we can get the number of the calibrations above the water, in the end conduct the water level value. Using this method, the devices are easily to install, can save cost, and has high precision, so it is suitable to apply in irrigation district.

	3. Identification and Speed Control of Ultrasonic Motors Based on Modified Immune Algorithm and Elman Neural Networks
	Qiao Zhang,Xu Xu
	Computer Science and Technology 29 October 2006
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:An improved artificial immune algorithm with a dynamic threshold is presented in this paper. Numerical experiments show that compared with the genetic algorithm and the originally real-valued coding artificial immune algorithm, the improved algorithm possesses high speed of convergence and good performance of preventing the premature convergence. The proposed algorithm is employed to train the network structure, weights, initial inputs of the context units and self-feedback coefficient of the modified Elman network. A novel identifier and controller are constructed successively based on the proposed algorithm. A simulated dynamic system of the ultrasonic motor (USM) is considered as an example of a highly nonlinear system. The novel identifier and controller are applied to perform the speed identification and control of the ultrasonic motors. Numerical results show that both the identifier and controller based on the proposed algorithm possesses not only high convergent precision but also robustness to the external noise.

	5. Three Dimensional Strain Field Morphing

	Computer Science and Technology 12 December 2005
	Show/Hide Abstract \| Cite this paper︱Full-text: PDF (0 B)

	Abstract:In this paper, we present a new technique for 3D shape morphing using strain fields. Strain is an important geometric quantity used in mechanics to describe the deformation extent of objects. We use it to analyze and control deformation in morphing. Using the position vector field, the strain field between source and target shapes can be obtain. This strain field is then interpolated between zero and its final value to give the position field for intermediate shapes. This method ensures that the 3D morphing process is smooth and no shape jittering or wobbling happens, and that locally, volumes suffer minimal distortion. We also show how to modify the method so that changes of shape (in particular, lengths) vary linearly with time.

	Abstract:In this paper we describe a neural network model-adaptive singular value extraction(ASVE) for multiple singular values extraction based on an extension of the Hebbian learning rule, and then apply it to image compression. The ASVE-based image compression scheme is based on the APEX–like algorithm proposed by Diamantaras. It is shown experimentally that the proposed scheme leads to good compression ratio and satisfactory image quality.

	8. An-OARSMan: An Obstacle-Avoiding Rectilinear Steiner Tree Algorithm with Good Length Performance

	Abstract:Routing is one of the important steps in VLSI/ULSI physical design. The rectilinear Steiner minimal tree (RSMT) construction is an essential part of routing. Since macro cells, IP blocks, and pre-routed nets are often regarded as obstacles in the routing phase, obstacle-avoiding RSMT (OARSMT) algorithms are useful for practical routing applications. This paper focuses on the OARSMT problem and presents an algorithm, named An-OARSMan, based on ant colony optimization. A greedy obstacle penalty distance (OP-distance) local heuristic is used in the algorithm and performed on the track graph. The algorithm has been implemented and tested on different kinds of obstacles. Experimental results show that An-OARSMan can handle complex obstacle cases including both convex and concave polygon obstacles with good length performance. It can always achieve the optimal solution in the cases with no more than 7 terminals.

	Abstract:acro cells, IP blocks, and pre-routed nets are often regarded as obstacles in VLSI routing phase. Obstacle-avoiding rectilinear Steiner minimal tree (OARSMT) algorithms are often used to meet the needs of practical routing applications. However, OARSMT algorithms with multi-terminal nets routing still can not satisfy the requirements of practical applications. This paper presents a 3-step heuristic, named FORSTer, to tackle the OARSMT problem. In Step1, we partition all terminals into some subsets in the presence of obstacles. Then in Step2, we connect terminals in each connected graph with one or more trees, respectively. In Step3, we connect the forest consisting of trees constructed in Step2 into a completed Steiner tree spanning all terminals while avoiding all obstacles. Two algorithms, called ACO-RSMT and GFST-RSMT, are proposed to construct OARSMT in a connected graph in Step2, which are suitable for different situations. This algorithm has been implemented and tested on cases

	Abstract:This paper studies and implements an integrated system for VLSI/ULSI physical design. The multi-layer mechanism is used to get great efficiency and speedup. The physical design system is integrated in three different layers, which are called the data interface layer (DIL), the data management layer (DML) and the data display layer (DDL). A quad-tree data structure is used in DDL to accelerate the graphics showing and the interaction between users and the system.
