In the process of big data analysis and processing, a key concern blocking users from storing and processing their data in the cloud is their misgivings about the security and performance of cloud services. There is an urgent need to develop an approach that can help each cloud service provider (CSP) to demonstrate that their infrastructure and service behavior can meet the users' expectations. However,...
This paper describes a new approach to the statistical characterization of high-speed interconnect circuits. The proposed approach is based on the idea of polynomial chaos and works by decoupling the matrices that arise from the Galerkin projection. The new approach is general in the sense that it can handle any polynomial system used in the generalized polynomial chaos(gPC) framework.
Traditional inspection robot for high voltage transmission line robot is hard to cross the drainage line and other non straight line segment obstacle because of the small operation space. A new bionic structure of the inspection robot is proposed in this paper, which is combined the motion characteristics of primates with the modern design method and the principle of bionics. The mechanism model based...
The paper describes a novel algorithm for timely sensor data retrieval in resource-poor environments under freshness constraints. Consider a civil unrest, national security, or disaster management scenario, where a dynamic situation evolves and a decision-maker must decide on a course of action in view of latest data. Since the situation changes, so is the best course of action. The scenario offers...
Software testing process is an important factor affecting the quality of software testing, which plays an important role in the entire software development life cycle. In order to achieve a precise result of testing, different software testing process model will be chosen in different software development process for testing. Traditional testing process model will be chosen in traditional software...
With the development of wireless communication technology, Internet users have higher requirements for QoS (Quality of Service) in wireless networks. The choice of feasible routing paths is inevitable in order to meet demand for services. As we know, in wireless environment the network status usually changes frequently and rapidly. In this thesis, we propose a QoS routing algorithm based on Vague...
Software testing laboratory is a professional software evaluation organization of university or state institution. Through the analysis and study of the characteristics of software testing process, we intend to customize a model of software testing process quality measurement which is applicable to the software testing laboratory. The model describes seven characteristics namely compliance of process,...

Saliency using natural statistics model has a good effect on obtaining the region of interest. However, it still has limitations such as insufficient image contrast, inability to cope with local information and so on. In order to overcome these challenges, an improved algorithm based on the two-dimensional Gabor filter and color maps is proposed. The two-dimensional Gabor filter has a close approach...
The popularity of QR code clearly indicates the strong demand of users to acquire (or pull) further information from interested sources (e.g., a poster) in the physical world. However, existing information pulling practices such as a mobile search or QR code scanning incur heavy user involvement to identify the targeted posters. Meanwhile, businesses (e.g., advertisers) are also interested to learn...
Noise margin violation, also known as voltage emergency induced by continuously reducing noise margin and increasing magnitude of current swings, is becoming a severe threat to the correct execution of applications in processors. Noise sensors can be placed in the non-function area of processors to detect such emergencies by monitoring runtime voltage fluctuations. In this work, we aim to accurately...
In recent years, with the rapid development of the Internet on a global scale and the prompt popularization of various App applications, the Internet is increasingly becoming an integral part of people's lives. Meanwhile various network problems caused by abnormal network behavior have become more prominent than any time before. Furthermore we also have a lot of personal information on the Internet,...
In a distributed network, there are multiple routing paths between source node and destination node. In order to meet certain demands of network security, selecting required firewalls in multiple routing paths and deploying appropriate rules on them are indispensable steps. Thus, in this paper, we carry on a further research on it and propose permit and deny algorithms which serve to improve the performance...
when organization select service provider (SP) in cloud computing based on service-oriented architecture (SOA), the optimal management of services is the kernel content of cloud computing from SP perspectives. However, it is difficult to realize the optimization of service selection in an open environment which contains large amounts of randomicity and uncertainty. In this paper, we focus on solving...
this paper proposed a new method to extract remote sensing road images based on the Hough transformation and the morphology. The road information is first extracted by using the Hough transformation to detect the direction and the width of main roads. Meanwhile, the morphology method is introduced to detect the corners and detail information of roads. The two images, which are extracted through Hough...
We describe a face detection system based on multiscale part models for drivers' fatigue detection. Our system is able to represent human face using two eye areas and one mouth area. By using mulriple simple template instead of single template with complex details, new model observably improved the computational efficiency and veracity for face detection. This system also considers the specialty of...
This paper describes the basic information of QR Code. Especially for the blurred QR Code image, we put forward an improved NAS-RIF algorithm which makes bimodal characteristic of the barcode image into it as a constraint. NAS-RIF algorithm itself has a good convergence speed. It will effectively improve the recovery effect of barcode image after combining with bimodal limit. The experiment shows...
Cloud infrastructure should accommodate changing demands for different types of transactions with heterogeneous requests workload and response time constraints. The multi-layer nature of service computing results in the difficulty of designing an optimal cloud infrastructure. The objective of the paper focuses on enabling clouds infrastructure to provide guaranteed performance in minimum cost. The...
A new electromagnetic loop with Voltage Class of 500kv and 220kv are constantly generated when 500kv power network is being constructed in China. Optimizing for the existing layering partition is of great significance to the safety and stably operation of the grid. The short circuit current calculation is crucial to the selection of grid's equipment and scheme for layering partition between electromagnetic...
Complex fault diagnosis is one of the most important areas of power system analysis. Currently the power supply system is complicated, the causal relationship for or logic of general unstick quantitative which determined by the structure exists between the input and output in a Complex fault system. Therefore, the mapping one-to-one simple relationship does not exist between the fault and sign, which...
