To improve yield rate and decrease production cost, wafer fabrication factory puts emphasis on the method of its process control and analysis. In recent years, many semiconductor foundries have invested a large sum of capital in Advanced Process Control (APC). In the field of APC, the induction and development of Fault Detection & Classification (FDC) is definitely one of the important parts....
In this paper, the storage management system is developed according to the Web-Based Enterprise Management (WBEM), so it is able to greatly relieve the management burden. Furthermore, a well-known standard named Storage Management Initiative Specification (SMI-S) is adopted in order to unify the storage management for different storage devices. In order to satisfy the Service-Level Objectives (SLO)...
Elementary stability results with robustness prametric issues are obtained for a class of nominally linear hybrid systems through total stability theorems based on fixed point theory. The class of hybrid systems is that of coupled continuous-time and digital systems subject to state perturbations whose nominal (i.e. unperturbed) parts are linear and, in general, time-varying.
The paper conducts a research on science research capability of national defense university based on the niche theory, in which an evaluation index system and dynamic evaluation model with the characteristic of stimulation of science research capability of national defense university is constructed. Then, a case is pulled into to illustrate the feasibility of the methodology from the empirical perspective...
For the dynamic topology and wireless channel features of mobile ad hoc networks, its security problem is always being a research focus. In the aspect of security routing protocol, the problem of how to enhance the security of mobile ad hoc networks was discussed in the paper. Based on the Ad Hoc networks structure and routing characters analysis, the requirements of Ad Hoc networks security routing...
It has been proved through the study of continuous automatic Form/Fill/Seal packaging machine that the final outlook quality of the package pouch is largely depended on the precise coordination between vertical seal drawing movement and horizontal non-constant speed rotation movement, i.e. to ensure the vertical seal drawing speed is the same with the linear speed of the horizontal seal rotation at...
In the research field of XML retrieval with keyword-based approach, a variant of Lowest Common Ancestors (LCAs) have been widely accepted to provide how keywords are connected by ancestor relationship. However, returning a whole subtree or a partial subtree based on LCA nodes is insufficient for identifying how subtrees are conceptually related under different tree structure such as ID/IDREF. On the...
The advantages and disadvantages about MATLAB are described in this paper. Several methods of mixed programming between MATLAB and other programming languages such as VC, VB and VC# are presented, including using MATLAB Compiler, MATLAB Engine, the third-party software Matcom, MATLAB Builder for .net to build COM component, MATLAB Visual Add-in and other methods. Finally analysis and suggestions about...
In this paper, by comparing among different equations of state, we would like to find one equation of state, which can be applied in wide range of pressures for fcc metals. The equations of state for fcc metals: Al, Cu, Ag have been studied with ultrasonic data. Compared with experimental DAC data, it is found that there is no equation of state, which can describe the compressibility for any materials...
Adapting a software system to the changing requirements and demands of the users is a big challenge in the area of software evolution. Representing these requirements in a high-level abstraction seems to be an optimal target. Model Driven Engineering (MDE) is one of the techniques that support this objective. Model transformation (automated and semi-automated), being the core mechanism in Model Driven...
In vector space models, traditional relevance feedback techniques, which utilize the terms in the relevant documents to enrich the user's initial query, is an effective method to improve retrieval performance. However, in this process, it also brings some non-relevance terms in the relevant documents in the new query. The number of non-relevance terms will increase according to the repeat of feedback...
Product redesign has been the main focus of Reverse Engineering (RE), especially for freeform shapes. Research in product redesign has led to the development of some interactive and intuitive deformation methods for freeform curves and surfaces modification with traditional two-dimensional based human-computer interfaces. Haptic interface provides new ways for human to interact with objects in virtual...
In the reference of ISO/IEC 9126 software quality model, this article establishes a comprehensive evaluation system of the software dependability. At the same time, it uses the concept of entropy to combine subjective weights and the entropy of objective weights to determine the weight values of measurements in the evaluation system. On this basis, take advantage of the trapezoidal-semi-trapezoidal...
I have designed a computer input device for the visually challenged people using a special type of sensors known as Wearable sensors. This system is completely wireless, doesn't require a normal keyboard. My main objective is to help the blind people to type easily. This keypad will be portable and error made during typing can be easily rectified, which is not available in the older methods.
A pipelined ADC with under-sampling technique is proposed. Under SMIC 0.35 um 1P6M process, the performance of SNR reaches nearly 66 dB with the condition that the sampling rate is 62.5 MHz and the input frequency is scanned from 1 MHz to 76 MHz except the Nyquist point. The typical power consumption is about 90 mW. Compared with Nyquist sampling, this design has lower power and less die area.
In this paper, distributed fusion filtering problem in multisensory dynamic system is considered. The approximation scheme for calculation of cross-covariances is presented, which are based on a correlation coefficient in steady-state. In addition, a new limiting cross-covariance method is also proposed, which gives the opportunity to save calculation times, and is computationally useful to implement...
With the development of economy and society, marine environmental pollution is becoming serious. It is of great significance to evaluate conditions of marine environmental quality correctly. This paper selected inorganic nitrogen, activated phosphate, dissolved oxygen and chemical oxygen demand as evaluation indexes. Then it established an evaluation model of marine environmental quality based on...
Tracking moving objects in video sequence is an important problem in computer vision, with applications in several fields, such as video surveillance and target tracking. As the shadows attached along with the moving object also have the same motion that of objects, the detection of shadows as foreground objects is very common and produce large errors in object localization and recognition. This paper...
Software reliability is a very important and active research field in software engineering. There have been one hundred of prediction model since the first prediction model published. Halstead model needn't test data and can be used before software test. But the model lost sight of many factors affecting software reliability. We aimed to improve prediction precision of Halstead model. So we improved...
In order to achieve energy saving and environmental protection, indicators of boiler must be controlled within an appropriate range. For 35T / H boiler of a winery factory, a set of intelligent control system is designed; the control model is established and solved through an advanced genetic algorithm to realize intelligent control of the system. The application results show that the system has perfect...
