Firstly,three vectors for each text are formed： the personal name Boolean vectors denoting whether a personal name occurs the text the biographical word Boolean vector representing title, occupation and so forth, and the feature vector with real values. Then, by combining a heuristic strategy based on Boolean vectors with an agglomeratie clustering algorithm based on feature vectors, it seeks to resolve multi-document personal name coreference. Experimental results show that this approach achieves a good performance by testing on ＂Wang Gang＂ corpus.展开更多

To detect histological characteristic of anterior cruciate ligament (ACL) and medial collateral ligament (MCL). Methods. In each of 20 skeletally mature male mongrels and 4 men, the ACL and MCL were examined by standard hematoxylin- eosin procedure and toluidine blue staining for histologic observation. Results. The fibroblasts in medial collateral are elongated to spindle shape and aligned in a row between the bundles of collagenous fibers. Toluidine blue staining is negative. The anterior cruciate ligament demonstrated more heterogenous cell types and arrangement. It had three major cell forms:spindle, round and ovoid type, which were shorter but greater than the cells in medial collateral ligament. Toluidine blue staining was positive in anterior cruciate ligament. Most cells in anterior cruciate ligament were enclosed within lacunae. Conclusion. This study suggests that the ACL has different histological characteristics from MCL, and is more cartilage- like in nature.展开更多

Negative Bias Temperature Instability (NBTI) is emerging as one of the major reliability concerns. Two software tools for NBTI analyzing are proposed in this paper, one for transistor-level, and the other for gate-level. The transistor-level can be used to estimate the delay degradation due to NBTI effect very accurately, while the gate-level can be used for repeat analysis in circuit optimization because of its fast computing speed.展开更多

Implementing a digital system to boiler quite a though work. This paper covers analysis from the experiment done to match with digital design that will be implemented to the real system. The digital control design will come up with the mathematical model and will be analyzed with MATLAB and SIMULINK software named as ＂Discrete Analysis ofBDT921 Simulation＂. A proportional integral and derivative （PID） controller is being chosen as the control element in discrete form as the real system is using the same control element. The output responses behave as the second order system with a bit difference in rise times and peak times compared with data obtained from experiment. With regarding to the analysis done, the digital control can be implemented and for further viewing, to be controlled digitally with computer in the control room.展开更多

It connects new or old numerical control (NC) machine tools which have inhomogeneous numerical control systems with CAD/CAM system by CANbus network. A DNC computer is able to control 15 sets of NC machine tools reliably at the same time. The novel DNC system increases the efficiency of machine tools and improve the production management level by realizing non-paper production, agile manufacturing, networked manufacturing and so on in the near future. Key technologies to construct the novel DNC integrated system include the integration of inhomogeneous numerical control systems, NC program restart, and algorithm for communication competition. Such system has demonstrated successful applications in some corporations that have acquired good economic benefits and social effects.展开更多

Traditional technique using mostly stop motion technique and experiment in any material animated objects, such as celluloid, sand, pebble, clay, doll, flour, or any objects that can be animated. This day digital technique is widely used mostly using computer hardware and software, and a lot of 2D animation software out there that can be used to create 2D animation. 2D Animation Hybrid Technique is a new technique that combining the traditional 2D animation technique but not using stop motion technique and with digital technique using computer and software, this technique become possible using image scanning technology that can digitizing any image from photo to hand drawn image. Then the sequence hand drawn animation edited in frame by frame also layer by layer using certain software in computer to create illusion of motion. The motion itself not just using any sense of art but also using physics, biology especially anatomy when needed to create such realism motion or perhaps funny motion in cartoon style animation.展开更多

The driving source for the daily motion is a rotary motor, while the elevation motion is performed with a linear actuator. The main task in optimizing the tracking mechanism is to maximize the energetic gain by increasing the solar input and minimizing the energy consumption for tracking. The design strategy aims to identify the optimum angular field for the daily motion, as well as the optimum actuating time in the step-by-step motion. The study is made by developing the virtual prototype of the tracking mechanism, in the mechatronic concept. The virtual prototyping platform includes the following software solutions： CATIA （Computer Aided Tri-Dimensional Interface Application）--to create the solid model, which contains information about the mass ＆ inertia properties of the parts, ADAMS （Automatic Dynamic Analysis of Mechanical Systems）/View--to model the mechanical structure of the solar tracker, and EASY5 ＆ ADAMS/Controls-for the control system design.展开更多

Excitation method of such a generator is shortly described. The output power of the SRG is controlled so that it can track the maximum output power of a wind turbine drive applications. Also, the output generator voltage is stabilized under either load or wind speed variations. Basic operational characteristics of a three-phase 6/4 SRG are developed through experimental observation. Meanwhile, the real-time operation was implemented in a DSP （digital signal processor） environment. The simulation of the complete system model has been obtained using the Matlab/Simulink software. A good agreement between experimental and simulation results has been observed which supports the validity of the proposed analysis.展开更多

In this study,a program based on the through-flow method was proposed, which had been verified by many other numerical examples. So as to improve the accuracy of the calculation, abundant loss and deviation models dependent on the real geometry of engine were put into use,such as: viscous losses,overflow in gaps, leakage from a flow path through seals. By means of this program, the aerodynamic performance of a certain high through-flow commercial fan/booster was investigated. On account of the radial distributions of the relevant parameters, flow deterioration in this machine was speculated. To confirm this surmise, 3-D numerical simulation was carried out with the help of the NUMECA software. Through detailed analysis, the speculation above was demonstrated, which provide sufficient evidence for the conclusion that the through-flow method is an essential and effective method for the performance prediction of the fan/booster.展开更多
