In reconstructing 3-D shape from images based on feature points, we usually define a triangular mesh that has those feature points as vertices, and display the object as a polyhedron. If the object itself is a polyhedron, however, some of the displayed edges may be inconsistent with the true shape. For this problem, Nakatsuji et al. proposed a method that automatically eliminates such inconsistencies...
Up to one third of the electricity supplied to a data center is required for the operation of the storage subsystem. A typical data-center workload, characterized by short idle periods, prevents traditional disk power management (DPM) from saving energy. This paper starts with an analysis of DPM's traditional timer-based disk spin-down policy. Next, we examine how a multispeed disk adapts DPM to datacenter...
An interactive desktop system for robot control is presented in this paper. The system consists of a digital desk, a markerless gesture interface and a line-follower. The digital desk is a network system composed of a camera, a computer and a projector. Hand motion is captured by the camera, and available gestures are recognized by the computer. The projector draws lines on the field where the line-follower...
In this paper, we present a non-symmetry and anti-packing object pattern representation model (NAM). The NAM model codes the geometry of generic object categories as a hierarchy of sub-patterns and each sub-pattern is represented by a rich set of image cues. The sub-pattern-based NAM model is designed to decouple variations due to affine warps and other forms of shape deformations. The combination...
Computer-aided design (CAD) system conventionally have been widely used to support designers for creating, modifying, adding something to or removing something from objects by showing simulated objects on computer screen. These virtual, non-physical, objects have been, however, known as imperfect imitation of reality. The impression of shape is highly related to the second order derivative of geometric...
Most legacy computer systems only well support input and display of 20,902 Han characters (Hanzis for short) encoded in Unicode 1.0. In 2010, Unicode 6.0 has encoded 75,616 Hanzis. However, it is not easy to use these newly encoded Hanzis, even in the latest computers. Most of these newly encoded Hanzis are rarely used in daily lives. Some are only used in ancient literature or individual Sinospherical...

The purpose of this paper is to broaden the application of Total Quality Management principles on maintenance issues for modern jet fighters as an attempt to further predict, improve and confirm reliability enhancement on critical aircraft systems, sub-systems or components. The proposed methodology is focused on the identification of under-performing maintenance cycles by instituting a reliability...
A shape feature-based and intersection-free method for morphing two planar simple polygons with corresponding vertices is presented. Based on the convexity-preserving morph of planar convex polygons and the convexity preserving morph of compatible planar triangulations with different convex boundaries, we present the method in this paper for the morph of two simple planar polygons which embeds the...
Mark as a specific visual symbols, is the integration and enrichment of corporate image, character, reputation, culture. It is the role of transmission business philosophy, content management, corporate culture and other factors to the public in order to reach the awareness and recognition of society to corporate and product. The combination of Computer software and logo design make the form of logo...
The logo of computer design is easier to identify, graphics have more features and personality, creation of color is free, unrestrained, and easier to stand out from the ordinary work, to achieve the purposes of publicizing the corporate philosophy. Comparison by setting off each other of different shapes and forms, highlighting the differences between each part of the whole, making the inherent character...
Morphing IFS fractal is a significant way to create new fractal mode ls. Many works have exploited this issue for various purposes, but without considering the appearance of fractal feature degeneration during the morphing procedure between two IFSs. In this paper, by calculating local attractor's coarse convex-hull and selecting rotative matching between IFSs, we design a new IFS correspondence method...
The national pattern is an unique form of symbol, a kind of special language carrier, which has the rich cultural connotations and diversity of aesthetic. Computer-fractal art is a new branch of mathematics, there have many uniformities between the national patterns and the computer-fractal, not only in the study, handling, and artistic features, most important, it is extending the scope of drawing...
Since the slice method have the advantage of less computation quantity and being easier to use, it is often used to solve the deformation of contact between crowned roller and race in rolling elements bearing analysis. Due to the neglecting of relationship among the roller slices, this method often had a low calculation precision in some instances. The paper presented a revised force-deformation relationship...
The text is very extensive application in the computer logo design. It is based on letters, character or numbers, combined with some appropriate visual presentation advantages of logo graphic design had such as unique, varied, clear meaning. In modern times, computer design logo designed based on basic shape of text has become an important part of the logo design. It is a symbol of fashion, a fashion...
About 200 skeletonization algorithms have been developed since 1950. It shows that there is a large variety of the problem which arises from the combination of the criteria used whether in its accuracy (size and shape) or speed. In this paper, a new idea to enrich skeletonization problem by reversing the approach is proposed. This new idea has an advantage in the algorithm speed. The proposed approach...
In simulation and computer game domains, two issues related to pathfinding problems are search algorithm and search space. This paper describes and compares four techniques used for the reduction of search space generation in 2-D simulation and game world environments. In order to improve the computational overheads, reducing size of search space is necessary. The size of search space is related to...
As emphasis on Science, Technology, Engineering, and Math (STEM) initiatives increase, students are at a fragile point in their education. It is imperative that students learn core skills like computer programming and procedural logic necessary to living in today's increasingly digital society. Our new game Shapemaker solves these problems in game-based learning that incorporates an engaging augmented...
This paper presents a method of fault polygon extraction and smoothing. It uses boundary tracking algorithm to extract breakpoint locations to form polygon file, and uses parameters of angles between fault polygonal lines as well as edge length and so on to do the work of smoothing, on condition that it keeps its original shape. This method improves the visual effect and aesthetic extent and offers...
