In order to enhance Zhenru Shanghai West Railway Station project management level and efficiency, Tongji University, cooperation with the inventors, developed 4D construction management system for Shanghai West Railway Station by establishing the Shanghai West Railway Station 4D information model and its information integration mechanism. The system implemented the construction visual simulation and...
Benefits of Building Information Model (BIM) for the construction industry are many and varied. Despite the benefits and the range of issues it can bring, BIM for the most part has been treated lightly in project agreement. According to the relatively-recent emergence of BIM and its evolving capabilities and uses, there is a general consensus that the industry must do better. In order to meet the...
Combining Geographic Information System(GIS) platform with three-dimension(3D) modeling and virtual reality technology, a strategy of visualization of 3D geological bodies and 3D orebody based on Supernatural GIS is proposed and the corresponding data structure is designed. By the direct human-computer interaction, many functions are realized, such as browse of dynamic panorama,3D virtual roaming,...
Commonly, surface and solid haptic effects are separated for haptic rendering. We propose a method for defining surface and solid haptic effects as well as various force fields in 3D cyber worlds containing mixed geometric models, including polygon meshes, point clouds, image-based billboards and layered textures, voxel models and functions-based models of surfaces and solids. We also propose a way...
Monte Carlo (MC) simulation of 9×9 Go games was implemented on a field-programmable-gate-array (FPGA) device. Significant speedup of over MC simulations on general-purpose CPU and over the previous implementation on FPGA was realized, making brute-force search of the Go game tree possible. Fixed depth alpha-beta game tree searches of 3 to 5 plies were implemented, and their playing strengths were...
In the present paper, the field emission properties of mixture of carbon nanotubes, ZnO tetrapods and conductive particles is discussed. To improve the field-emission further, a field-emission cathode with special edge structure is proposed in this paper. In Figure 1, the silver cathode electrode is first coated on a glass substrate. Then, carbon nanotubes are deposited on the cathode electrode as...
To improve the performance of a field-emission device, a metal mask is introduced in the field-emission triode in this paper. The background noise of the anode current can be decreased by the shielding effect of the metal mask. The electron beam can also be focused by the convergence field around the metal mask.
In practical engineering, the earth pressure of retaining wall caused by the local load of the surface of inclined fill cannot be calculated by Rankine theory. Based on this problem, the paper introduces the practices and skills; presents the new methods with infinitesimal calculus; anal sizes the effect of the two methods for the anti-slide of retaining wall and the steady of anti overturning with...
With the decrease in France of the number of students in the field of electrical engineering and information processing, that is unfortunately more and more common in Europe, several French Institutions are trying to build remote formations in Asia-Pacific region. This paper deals with the setup of a new master degree in the field of electrical and information engineering with two specialties, microelectronics...
A secure scheme based clusters for wireless sensor networks is presented. The three-dimension sensing cube is divided into a number of clusters, each of which is comprised of eight small cubes called cells. The structure of WSNs is a two-layer structure. The upper layer contains all cluster heads and the lower layer contains all ordinary sensors managed by corresponding cluster heads. The cluster...
A pairwise key establishment scheme based cells and logical groups is presented in this paper through utilizing the overlap key sharing (OKS) concept. The sensing cube is divided into a number of small cubes, eight of which consist of a logical group. Analysis and comparison demonstrate our mechanism has a good resilience against node capture, realizes flexible secure grades, and has good network...
Routing protocol has been a challenging issue in the design of wireless sensor networks. Efficiency and security are two topics in the design of routing protocol for WSNs. Some efficient and secure problems in LEACH protocol are solved in order to substantially improve the performance of the LEACH protocol. The new protocol consists of a number of rounds. The sensing area is divided into a number...
An electrically tunable bandpass filter based on two photonic crystal fibers filled with different liquid crystals is demonstrated. Both the short-wavelength and long-wavelength edge are tuned individually or simultaneously with the response time in milliseconds.
This paper presents a template-based facial caricature generation approach. Since the major difficulty in generating facial caricature automatically is the uniqueness of individuals and the polymorphism of features, a modified active shape model (ASM) is first designed to locate key feature points accurately by using 2D local grey-level structures. Then, extracted facial components are classified...
A three-step method for quasi-frontal face caricature generation is presented in the paper. First a CLM (constrained local models) and CQF (convex quadratic fitting) based face alignment approach is utilized to obtain initial locations of key facial features. Then facial components (eyebrow, eye, nose and mouth) are classified respectively into different categories defined by configuration and appearance...
We propose a framework for visual and haptic collaboration in 3D shared virtual spaces. Virtual objects can de declared as shared objects which visual and physical properties are rendered synchronously on each client computer. We introduce virtual tools which are shared objects associated with interactive and haptic devices. We implement the proposed ideas as new pilot versions of BS Collaborate server...
The field-emission cathode has potential application in the field emission display panels, high frequency amplifiers, X-ray sources, cathodoluminescent light sources. In a field-emission display device, the field-emission has to be modulated sensitively. Therefore, a few kinds of field-emission triode, such as normal-gate, under-gate and lateral-gate have been proposed. To simplify the fabrication...
Vasodilator stimulated phosphoprotein (VASP) is associated with focal adhesions and is thought to be crucial regulators of actin dynamics and associated processes such as cell adhesion and motility. A study was undertaken to analyse VASP expression in normal gastric tissue and gastric carcinomas. Human gastric tissues with adenocarcinomas (n=42) were used. Normal gastric tissue specimens (n=6) were...
