Visual target tracking is one of the most important research areas in the field of computer vision. Within this realm, multiple targets tracking (MTT) under complicated scene stands out for its great availability in real life applications, such as urban traffic surveillance and sports video analysis. However, in MTT, main difficulties arise from large variation in target saliency and significant motion...
With the yearly increase of the amount of Android users, malicious applications for mobile terminals are emerging in endlessly. Many researchers have started to explore how malicious apps are detected from the perspective of network traffic. We design and implement a control and management system of Android traffic collection, which contains the functions of downloading APKs, malware static detection,...
Based on the differently implicational idea, the a-universal multiple I restriction method is put forward for general fuzzy reasoning, which contains the a-multiple I restriction method as its specific case. First of all, we give the a-universal multiple I restriction principle, which improves the previous restriction principle, and then provide the existing condition of the solutions of the new method...
Single thread performance is still a matter of concern even for multicore systems. Making good advantage of on-chip cache memory is critical in improving single thread performance. However, as the distributed layout of on-chip cache, single-threaded applications only use limited cache capacity of the whole system, while leaving others idle. Besides, data sets of a thread, which present strong localities,...
In order to find out more suitable water for Vi o la tricolor irrigation, the effect of three water source with different salinity on growth, photosynthesis, and chlorophyll content in two cultivars of Viola tricolor were investigated. The results show that the underground water in Xinxiang (EC=2.98 ms/cm) decrease the seedling germination percent in both cultivars, while significantly in ‘229.05’,...
It is important and difficult to develop spatial imagination and thinking ability in engineering graphics course. Try to use a new graphics teaching methods in Mechanical Engineering, which is to open engineering graphics course and Autodesk Inventor8 education three-dimensional modeling technology elective course at the same time. This paper introduces the setting conditions of Autodesk Inventor8...
Thread Level Speculation (TLS) is a technique aims at boosting the performance of sequential programs running on Chip Multiprocessors (CMPs) by automatically parallelizing them. It exempts programmers from the heavy task of parallel programming. But its performance may suffer from frequent squashing caused by inter-thread data dependency violation. In this paper, we propose a Network-on-Chip (NoC)...
In the biodegradation of Formaldehyde gas with a biotrickling filter, a portion of Formaldehyde is solved in the recirculating trickling liquid. As a consequence, the treatment efficiency is limited. The study explored the feasibility of removing the liquid-phase formaldehyde by inducing chemical reactions in the trickling liquid. Experiments were conducted to test three chemicals (sodium sulfite...
This paper examines the role of stretching mutual fund families and manager reputation in China using the new fund issuing data from 2004 to 2010. We find that managers with higher reputation attract more fund inflows to new funds, with four months spill-over effect to seasoned funds. Meanwhile, past performance of prestigious managers can persist in new funds, and performance of new funds run by...
Reputation stretching is a marketing strategy for promoting new fund sales. We examine the role of this strategy in Chinese mutual fund families and find the similar result as Chen and Lai (2010). We find Reputation stretching increases net fund flows to fund families, and past performance of prestigious managers can persist in new funds. Meanwhile, performance of new funds run by managers with track...
Objective: This study aims to create twelve numerical models of implant-supported attachment-retained complete maxillary dentures by an efficient CT image segmentation and mesh creation technique, as well as evaluate mechanical characteristics of Model 1. Methods: Masks were first created after identifying regions of interest on CT scan images of maxillary prosthesis, then integrated with CAD models...
This paper investigates relationship between investment of mutual fund managers from different cities and different fund families in China. The results show that “own-city” effects are larger than “other-city” effects. A mutual fund manager is more likely to buy (or sell) a particular stock in each semi-annual if other managers in the same city are buying (or selling) that same stock. This evidence...
According to extensible set theory, the definition of extension classification based on extension transformation is presented. The acquiring methods and application on extension classification are discussed on information element set. Through its dependent function values of information element before and after the transformation decide its extension categories and obtain the extension categories...
This paper proposed a new 2-dimension-code-like feature based on the Haar-like feature proposed by Viola et al. The feature can be calculated in different scales rapidly once the integral image is calculated and this characteristic is inherited from the Haar-like feature. Instead of reducing the dimensions after calculating redundant features, we calculate feature vectors with fixed dimensions for...
Mutual fund managers' frequent replacement implies fund companies' recognition to their skills. In order to capture this kind of managerial skills, we put forward two propositions: performance persistence is stronger in large fund and fund abnormal return is negatively correlated with managerial tenure. Using a panel of 96 actively managed Chinese equity funds, we document evidence consistent with...
It mainly introduces that proportional decompression valve which substitutes for original PPC valve is used as priority valve to make up of digital electro-hydraulic proportional directional valve with multiple unit valve, which fulfills digitized electro-hydraulic proportional control for bulldozer working device. First apply Simulink in the software MATLAB to simulate the dynamic characteristic...
Faced with the quick development of advanced scientific techniques and manufacturing techniques, China must speed up its complete change process from ldquosuper manufacturing countryrdquo to ldquoinnovation powerful countryrdquo. As one of the national pillar industries and the representative of complex product, automotive industry has already marched towards complete independent innovation. Nevertheless,...
As one representation of typical complex products and national pillar industries, Chinese automobile product and industry is falling into more intensive competition. To be the winner of the marketing competition which is full of native and overseas competitors, all member enterprises should cooperate each other to pursue the maximum integral profit to realize the win-win status and long-tern sustained...
Along with science and technology fast development and people living standard universal enhancement, customer demand on the scope of product and service becomes wider and wider, and their request level becomes higher and higher. Now the society has already entered the period of "competition between supply chains". It is more and more impossible to achieve the target of improving customer...
In this paper, we present an adaptive refinement ratio algorithm for structured adaptive mesh refinement (SAMR) method based on SAMRAI framework. We developed our algorithm based on an example application program of SAMRAI framework, an AMR Euler gas dynamics application. The Euler class of this application provides routines for a sample application code that solves the Euler equations of gas dynamics...
