many distributed storage systems have been proposed to provide high scalability and high availability for modern web applications. However, most of those applications only aware data skew while actually request skew is also widely exist and needed to be considered as well. In this paper, we present a request skew aware heterogeneous distributed storage system based on Cassandra-a famous NoSQL database...
Today's fast developing modern information technology not only has a great impact on the social and economic activities but also more importantly has caused the innovation of modern auditing technology. In order to keep pace with the development of modern audit, the author adopted the method of computer data mining to analyze large quantities of data collected from the audited corporate, and work...
This paper presents a novel risk assessment model for software projects. Traditional software risk assessment models lack the capability of classifying risk events based on their (in)dependence and statistical (in)dependence. The proposed risk assessment model relies on a scheme to classify the risk events of the software project based on their (in)dependence to occur and statistical (in)dependence...
This paper suggests an approximate algorithm to solve general 0-1 integer programming problems. This algorithm belongs to the class of lexicographic enumeration algorithms. Theoretical analysis and a strict mathematical proof of convergence property of the algorithm are presented , as well as experimental investigation to engineering structural optimization with good results.
The balanced scorecard is a management technique developed by Harvard professor Robert Kaplan and consultant David Norton. Instead of focusing solely on financial objectives, the balanced scorecard is an integrated set of performance measures organized around four distinct perspectives - financial, customer, internal, and innovation and learning. The balanced scorecard helps business leaders manage...
In hospitals, there are usually many legacy equipments and software systems, which may not provide standard interface for integration or even do not have its own API for outside accessing. This makes it very hard to integrate those legacy systems with health information system. It becomes a big challenge for health information integration if you want to provide a total Health Information System for...
Fault tolerance is a central issue in the design and implementation of interconnection networks for large parallel systems. Connection probability of a network is a good network fault tolerance measure. For a mesh of given size and node failure probability, the gap between the known upper and lower bounds on the connection probability is often very large. In this paper we design algorithms to estimate...
This paper presents a novel approach to stabilize video sequences based on low-rank matrix decomposition. Compared to previous methods which are based on simplified models, our stabilization system can work in situations where significant depth variations exist in the scenes and the camera undergoes large translational movement. We formulate the stabilized frames as a low-rank matrix. This allows...
Product design is an essential part of the new product innovation, which is affected by availability of financing. In the paper, we study the relationship between financial services and capacity of product design, and examine whether capacity of product design contributes to the improvement in performance of the small and medium manufacturing enterprises. The research shows that, financial service...
Wireless sensor network will enable the reliable monitoring of a variety of environments for several application like in military, forest, etc. This paper focus on the communication routing protocol which has impact on network lifetime and scalability. The sensor network lifetime is a function of energy. LEACH (Low-Energy Adaptive Clustering Hierarchy) as routing protocol of sensor network for energy...
With the repaid development of multi-media and network, information are generated and spread quickly than before. New application such as search engine, video share depends on the scale and access speed of huge data set. Data-intensive computing became a hot point of computer science. In Data-intensive environments, data access ability is the bottleneck instead of computing ability. In this paper,...
Based on the review of past research papers, this article analyzes the functioning mechanism of accumulated points which are tightly connected with the choices of individual effort by two dimensions of "self-consciousness" (private self-consciousness, public self-consciousness). We advance related hypotheses and validate those hypotheses by survey samples. We draw the conclusion that medium...
Base on Intel Math Kernel Library (MKL), the paper mainly focus on the research and realization of software radar signal processing, which includes magnitude, accumulation and Constant-False-Alarm-Rate(CFAR). Firstly, paper introduces simple signal processing flow of conventional search radar based on ship, then gives the detailed analysis on magnitude, accumulation and CFAR processing module's computing...
The increased popularity of the proactive security paradigm aggravated the need for distributed surveillance systems. These systems are built using smart sensor networks which cover large areas of civilian concentration. Such networks need intelligent management systems to control the large number of sensor nodes and the large volume of data. Sensor Management Frameworks (SMF) aim to coordinate the...
Wall slip behavior of sludge was studied experimentally by using a rotational rhehometer with parallel plate fixtures and checking the possible influence factors on sludge wall slip based on the gap dependence of the stress/ strain data. In the steady shearing flow it was found that there seems to be no critical shear stress for the onset of slip of sludge, while concentration is the important influence...
This paper conducts empirical analysis on exchange rate pass-through to import and export prices in China with monthly data from 1999 to 2008, and finds that exchange rate pass-through is higher to export prices than to import prices. The analysis shows that the difference in the pass-through of exchange rate to import and export prices arises from the difference in industrial margin, international...
Life cycle assessment (LCA) as method, large-scale public buildings which areas are over 20,000 square meters each in Hangzhou of hot summer and cold winter region as objects, the paper studies on the features and rules of CO2 emission and energy consumption. With three typical cases being selected among office, health care and campus buildings, variation of carbon emission indexes are calculated...
Today, the emergence and booming of Cloud Computing brings unprecedented impact to traditional enterprise connectivity market at the same time of bringing huge impact to IT architecture and enterprise computing environment. The requirements of integrating numerous on premise application and off premise application or service, and the IT cost effect coming with Cloud Computing lead enterprise expediting...
Traditional teamwork theories are widely applied in relevant researches and practices, but they are based on the hypothesis that human beings are selfish. However, emerging behavioral economics has well proved that human beings have fairness preference. New theories based on that are coming into being gradually, and possess significant implications for a wide scope of researches. By applying the fairness...
A user-centered new product development process is discussed in this paper. The design of a new sports earphone is illustrated as a case study. User study methods such as questionnaires, survey, interviews and observations are used. Quantitative and qualitative methods are used to create Persona, scenario and discover user requirements. Quality Function Deployment (QFD) method is used to translate...
