With the rapid development of information technology, the computer has been more and more important in our lives. Especially it makes our working, learning and entertainments, and even consumptions dependent on the computer increasingly because of the popularity of network. However, the computer has brought us a lot of convenience, while it also makes us face with a variety of security risks. Computer...
Hardware in the Loop Simulation(HILS) plays an increasingly important role in the development and test system of missile. This paper describes the structure and function of a typical HILS Platform for missile testing. The platform has a double computers structure, which consists of the control computer and the simulation computer. The paper analyses the hardware and software requirements and gives...
Several studies have proved the efficacy of computer assistance in spinal surgery, especially in the technique of pedicle screw insertion for vertebral fusion and correction of deformities. Computer assisted surgical navigation systems have proven success in the surgical treatment of spinal fractures and disorders. We have developed a novel method for real time computer assisted spinal surgery, based...
A visual-based auxiliary navigation method using augmented reality is an immersive navigation interface with virtual navigation and decision-making information superimposed on the video of real environment. It can provide the operator with more information to behave proactively in order to forestall future problems, with less stress or effort, and to increase the successful rate of UAV missions. The...
This paper proposes an efficient score tracking system that can track musical performance on a score in real time. This kind of technology is called score following. It can be used in wide range of applications. Our algorithm is like Dannenberg's Dynamic Programming algorithm but extends his algorithm to process polyphony music. Ideally, the notes of polyphony have to be played at the same time. But...
Mobile multi-robot systems are a main focus in robotic research. An obvious advantage of operating with several robots is the fact that solving problems like exploration cooperatively is better, faster and more precise. But there is potentiality for another enhancement, namely the distribution of necessary tasks and algorithms to available computers in such a way that as much processing time as possible...
This paper researches on the real time subdivision of surface rendering using approximation scheme and focuses on two methods — Catmull-Clark and Loop subdivision. The two methods are commonly employed separately in many existing applications and graphics engine. Catmull-Clark outperforms on quad meshes and Loop subdivision superiors on triangle meshes. The exchange of the meshes produces ugly polygonal...
Power quality problems such as three-phase unbalanced and aberrance, harmonics and so on, have become serious increasingly and the development of APF has been one of the ways to solve these problems. The detection algorithm based-on FBD theory for command current in three-phase and four-wire system, can extract the zero-sequence current and harmonic current from the load current. This algorithm is...
The main objective of this paper is to investigate online evolution of military unit combination strategies for winning an offensive rush in a real-time strategy (RTS) game. A modified version of Evolutionary Programming (EP) is used as the evolutionary optimizer while WARGUS is used as the RTS gaming environment. Evolution of the military unit combinations is conducted online, which means that optimization...
Type-2 fuzzy logic systems that use general type-2 fuzzy sets (GT2 FSs) are now receiving renewed attention; hence, it is important to be able to communicate effectively about such fuzzy sets. While it is possible to generate the 3D membership functions (MFs) for these fuzzy sets using computer programs, this is not very useful for real-time on-the-fly discussions. Additionally, for most of us it...
The online course registration system is the central part of the educational administration system, which consists of registration guidance, registration controlling, undergraduate course registration, graduate course registration, retaking and retesting, dropping the course in the middle phase and information exchange, etc. The new course registration system at Tsinghua University was put into use...
Distance calculation is always one of the most important goals in a digital stereoscopic vision system. In an AER system this goal is very important too, but it cannot be calculated as accurately as we would like. This demonstration shows a first approximation in this field, using a disparity algorithm between both retinas. The system can make a distance approach about a moving object, more specifically,...
The number of files stored in a personal computer is increasing very quickly, so it is difficult for users to find the information they want. One desktop search engine named SoDesktop is proposed in this paper, which is composed of four modules including Data crawler, Task scheduler, Data indexer and Data searcher. The implementations of these four modules are described in details, and the implementation...
Atmospheric effects are one of the important factors that affect the physical realism of the infrared (IR) scene generators. IR scene generators obtained by OpenGL library are used in the applications where performance is critical. Modeling atmospheric effects in the IR band using OpenGL's fog model approach is found in the literature. However, the related fog model needs parameters that are independent...
Many recent advancements in testing concurrent programs can be described as novel optimization and heuristic techniques for exploring the tests of such programs. To empirically evaluate these techniques, researchers apply them on subject programs and capture a set of metrics that characterize the techniques' effectiveness. From a user's perspective, the most important metric is often the amount of...
Recent advance in the space application has increased the requirements for more real-time and reliable on-board computation. Running in a harsh space environment, on-board computers could suffer transient faults, such as single event upset (SEU) frequently. Reloading tasks or rebooting system may recover these faults, but they have seriously effects on deadlines of tasks and increase resource and...
We live in an era where billions of computers are interconnected. In the very near future, not only computers but also many different digital devices and other physical objects will be seamlessly connected to each other and be able to communicate with little or no human intervention. These interconnected objects are called smart devices, and this concept is called Internet of Things. In this paper,...
Texas Instruments (TI) has created the Signal Processing Education Network (SPEN) Fellows program to help identify and fill content gaps within the signal processing content library hosted on the Connexions ecosystem. This paper will overview Connexions, SPEN, the SPEN Fellows program, and review this year's SPEN Fellows project involving Connexions content creation involving real-time DSP (RT-DSP).
Artificial Intelligence and web when amalgamated, it may produce miracle in terms of semantic web and its one of the important application is in E-Learning. E-learning works efficiently only when E-Content preparation is need based, customizable and on-demand, preparation is real-time, searchable through keyword/s. This paper describes development of a methodology for rule based customizable e-content/e-book...
Task scheduling in real-time systems is a concept by which we can schedule the tasks according to their priorities. In hard real-time systems, the task scheduling is more important due to the chance of system failure. We discuss EDF task scheduling which is an optimal technique for the uniprocessor systems. The existing result of the QPA algorithm was applied on the uniprocessor system to check the...
