We consider a challenging class of highly interactive virtual environments, also known as Real-Time Online Interactive Applications (ROIA). Popular examples of ROIA include multi-player online computer games, e-learning and training applications based on real-time simulations, among others. An emerging enhancement for ROIA is the use of mobile devices for accessing the application (mobile ROIA). However,...
The steep growth of digital-content consumption and increasing reliance on wireless networks has resulted in emerging standards such as IEEE 802.11ac. By employing spatial diversity, Multi-user MIMO and high-density modulation (up to 256-QAM), 802.11ac MIMO radios can provide significantly increased throughput, link robustness, and range while maintaining backward-compatibilities with existing 802...
The ant colony algorithm to optimize the fitness test time arrangements, and original ant colony algorithm has been improved, the improved selection strategies and pheromone adjustment guidelines to effectively improve the convergence speed of reconciliation performance, final for instance using a computer to calculate, and achieved good program.
Mutual modes derived from Chromatographie fingerprints of high-quality traditional Chinese medicine (TCM) can provide standards for quality assessment. This paper demonstrates a new method to apply non-negative matrix factorization (NMF) in deriving mutual mode from high performance liquid chromatography (HPLC) fingerprints of TCM. The HPLC fingerprints of the same species of TCM are taken as data...
An intracorporeal optical tracking system for minimal invasive (MIS) surgery is proposed. MIS has been widely used in laparoscopic surgery since 1980s. Its advantages include small surgical cuts and short recovery time. However, because of the limited workspace and narrow view, MIS is more complicated and costs more time than open surgery. Therefore, the image-guided system plays an important role...
This paper proposes statistic learning based Qlearning algorithm for Multi-Agent System, the agent can learn other agents' action policies through observing and counting the joint action, a concise but useful hypothesis is adopted to denote the optimal policies of other agents, the full joint probability of policies distribution guarantees the learning agent to choose optimal action. The algorithm...
It is very important to explore the combination of college English teaching and multimedia technology, because it is the unstoppable trend. The advantage and existing problem of multimedia in college English teaching is analyzed. The cooperative learning and the teaching evaluation mode with "the double connection" are integrated to play the role of multimedia technology in college English...
The interval-valued information system is a generalized form of a single-valued information system. In this paper, four existing dominance relations and the α dominance relation are analyzed. And a new α-β dominance relation is proposed for multiple attribute decision of the uncertain attribute weights problem. Furthermore, an interval-valued multiple attribute decision model based on the α-β dominance...
A block-based adaptive median filter, which aims to purify impulse noise from an MRI image, is discussed in the paper. The proposed filter blocks the image into several sub-images, and calculates the standard deviation of each sub-image. During filtering process, each point of the sub-image needs to be judged whether it is noise point or not, according to the average value of the filtering window...
Researchers have made considerable progress in the development of Earth Observation (EO) technology since 1960s. EO satellites usually span a quite wide wave-band from visible to infrared light or even to microwave. In this paper, we propose an optical design on multi-waveband spaceborne EO system. The design scheme adopts a coaxial two-mirror optical system together, which is able to image into visible...
This study investigates the device characteristics of the ultra-thin body (UTB) SOI MOSFETs with different channel lengths. The device reliability, body charging effect, and oxide trap distribution are also studied. The P-type device reveals more degradation of the threshold voltage than that of N-type device as decreasing the channel length. For the effect of body charging on ultra-thin Si-body,...
Illumination variation generally causes performance degradation of face recognition systems under real-life environments. The Self Quotient Image (SQI) method [1] is proposed to remove extrinsic lighting effects but requires high computation complexity. Therefore, we propose a low cost face recognition scheme that uses multi-scale down-up sampling to generate self quotient image (DUSSQI) to remove...
This article puts forward an idea of generating emergency plan under the “scenario-task” perspective and clarifies the main content and key technology roadmap of the research starting from problems existing in the domestic emergency plan. Based on the summary of typical emergencies evolution, by means of making the research on the classification and grading of emergency scenarios and the constitution...
Therapeutic ultrasound transducers can carry out precise and efficient power deposition for tumor thermal therapy under the guidance of magnetic resonance imaging. For a better heating, organ-specific ultrasound transducers with precision location control system should be developed for tumors located at various organs. It is feasible to perform a better heating for breast tumor thermal therapy with...
This study evaluates the biomechanical interactions of a mini-implant using a plastic revolving cap (PRC) with translation/rotation features for optional orthodontic traction. An orthodontic mini-implant and the PRC consisting of a hexagon connection onto mini-implant with 60 degree switching unit and an extended arm to provide orthodontic wire tied at different positions. The PRC removal force was...
Introduction: Many microvascular anastomoses have been proposed for use with physical assisted methods, such as cuff, ring-pin, stapler, clip to the anastomose blood vessel. The ring-pin type anastomotic device (e.g., 3M Microvascular Anastomotic System) is the most commonly used worldwide because the anastomotic procedure can be conducted more rapidly and with fewer traumas than using sutures. However,...
This paper, based on the development history of Dalian GONA technology Co., Ltd., investigates enterprises' independent innovation mode established by integrating internal and external resources in face of changing demand and continuous competition. It finds that the core of enterprises' independent innovation lies in the integration of internal and external resources, and mode is the integral network...
Chinese and Taiwanese share many similarities in their culture, language, politics and lifestyle. And Taiwanese firms are quite familiar with the institutions and economic environment in China, therefore, Chinese market will continue to be an important market for Taiwanese firms. This study takes Taiwanese manufacturing firms in China as an example, and refers to the Dunning's framework to develop...
We investigate the resonantly side-pumped 1645-nm Er:YAG crystal fiber laser utilizing a gold-embedded grating coupler. The 91.5% pump coupling efficiency and 73% laser slope efficiency can be achieved in a 18-cm double-clad crystal fiber laser.
In China, the wind farm is usually with large capacity, centralized, multipoint into the grid and far away from the loading area, which lead to the link between the wind farm and power grid is weak, and the impact of wind power on power system extends from local area to the system stability. Meanwhile, the structure and characteristics of wind turbine generator (WTG) are different from those of conventional...
