Software testing usually accounts for a large proportion of software development time and cost. Thus, it is crucial to improve test efficiency and reduce test cost as much as possible. This paper describes a cloud-based approach to increase test efficiency by partitioning a large test job into multiple tasks and executing the tasks concurrently on different virtual machines (VMs). Several task partitioning...
With the rapid development of computer and network technology, micro-blog system provides to exchange information and proceed social life. It provides very favorable ways. Especially, how to quickly obtain information and release information, sharing of information in today's society become a research direction for a big data. In this paper, we based on Struts2, JSP, MySql, Ajax and JQuery related...
Appropriate subspace projection enhances the characteristics of the desired signal power and reduces the interference effect. This paper proposes an algorithm that uses projection subspace to estimate the direction of arrival (DOA) for coherent signals without signal source number information. First, the joint diagonalization structure of a set of Toeplitz matrices constructed from the covariance...
Multi-Project Wafer (MPW) is designed for cost saving and fast prototype but conventional Blade Dicing process is time consuming and high risk to cause die loss because repetitive Blade Dicing process. Stealth Dicing is an alternative solution of Blade Dicing, patterned by Hamamatsu Photonics, which has potential for MPW dicing solution. This paper presents first successful MPW dicing by Stealth Dicing...
Over the past few years we have seen explosive growth in the amount of data and researchers are now facing greater challenges in dealing with heterogeneous data increasing in an unprecedented speed. There is a clear need for intelligent surveillance systems since the size of video data has become too large to be reviewed by humans. In this paper, we propose an unified computational framework, which...
We study the question of hand posture recognition by developing a new class of Bag-of-Features (BoF), namely Hierarchical BoF. The Hierarchical BoF captures spatial information by dividing whole hand area into several sub-regions and projecting local features onto horizontal and vertical directions. A similarity measurement based on Histogram Intersection Kernel (HIK) is proposed to classify hand...
In traditional fractal image compression, the encoding procedure is time-consuming due to the full search mechanism. In order to speed-up the encoder, we adopt particle swarm optimization method performed under classification and Dihedral transformation to further decrease the amount of MSE computations. The classifier partitions all of the blocks in domain pool and range pool into three classes according...
In the process of OLAP analysis based on multi-dimensional data, analysts are often involved in large-scale data cube, which results users cannot find the interest information efficiently. To overcome this problem, some exceptions mining or exceptions-based methods were proposed. In this paper, a new regression-based definition of exception is proposed, threshold exception, and following which an...
In the daily life, people often repeat regular routes in certain periods. Predicting personal future routes using this information helps to achieve many goals, including improving the quality of intelligent transportation systems (ITSs) and location-based services (LBSs) for individuals. In this paper, a novel system is developed to predict the personal future routes based on the continuous route...
Biclustering the gene expressing data is an important task in bioinformatics. A parallel biclustering algorithm for gene expressing data is presented. The algorithm starts from the data sets containing pair of rows and columns of the data matrix, and gets the biclusters by gradually adding columns and rows on the data sets. A pruning technique is also proposed to reduce computing time. Experimental...
