The personal health records (PHR) always contain much health-related privacy information in different categories. When storing the PHR data in the cloud, the PHR owner losescontrol to the sensitive information and is confronted with potential privacy exposure. In this paper, we propose a scheme to enable the protection of the PHR data hosted in the cloud. It not only supports that the data access can be fine-grained and base on the privacy policies specified by the PHR owner, but also affords an effective encryption mechanism and flexible key management approach to enforce the privacy policies sticky to the PHR data. © 2013 Universitas Ahmad Dahlan.

This paper studies the quality management method in small-size software project. In traditional method, test and evaluation are prerequisite methods to improve the project quality. The paper analyses characteristics and the disadvantages of project management in small-sized software project. Therefore, some quality activities should be considered in small-sized software project. The paper proposed lightweight quality planning, quality execution and quality monitoring activities in project management. Finally, the paper gives practical applications and proves method effective.

Provenance plays a fundamental role in e-science to keep track of the data processing execution, evaluate the data quality, reproduce the analysis results, and especially share and re-use workflows. How to take full advantage of provenance to help scientists discover, match and select scientific workflows is a challenging work. Although some studies have been done to model, store, and query scientific workflows, little is done to build practical systems to support workflow matching and discovery. In this paper, we devise and implement a Provenance-Based Workflow Matching and Discovery System (PWMDS) for task-based pipelines in a proteomics data analysis platform called CoPExplorer to address the above challenge. With the proposed novel provenance model and workflow matching & discovery algorithms, PWMDS can provide scientists a ranked list of suitable service candidates for their specified workflows, and initial experiments demonstrate its effectiveness. © 2012 IEEE.

The intrinsic construction project nature of one-of-a-kind and the requirement of massive data exchange make collaboration one of the critical factors towards success. However, due to the complexity of multiple phases and multi-disciplinary participants in project life cycle, industry level collaboration in Architecture, Engineering, and Construction (AEC) sector remains a challenge. This paper proposes an integrated solution based mainly on social network services (SNS) and cloud computing. We present a novel platform named Construction Business Social Network Service (CBSNS), which is promising to be adopted as an industrial scope collaboration cloud. We describe its main functions as well as its privacy control mechanism. To better support its deployment as a community cloud, a three-pass load balance algorithm is proposed. The first pass sorts initial virtual machines (VMs) and physical machines (PMs) using bubble algorithm, during which parameters such as hungry threshold are considered. The second pass builds mappings between allocable PM queue and requesting VM queue using first come first served strategy, and groups Non-allocable VMs after designated time slice. The third pass handles possible exceptions when finally such ones existing. The actual time complexity of the algorithm is O(n). While the commercial implementation of the algorithm is ongoing, the proposed CBSNS has been developed and used in real life application. © 2012 IEEE.

In this paper, a novel software testing evaluation model is proposed for specification based software testing. The proposed model uses Analytic Hierarchy Process (AHP) to analyze the weight of influence each individual function unit software, then the model classifies the defect ratio of each function unit based on the weight of influence derived from step one and calculates the final evaluation result of software testing according to the defect ration and influence degree. © 2012 IEEE.

As the weight of the general system characteristics (GSC) in IFPUG method is the same in the different types of software systems. To solve the problem, this article uses the Fuzzy AHP (Analytic Hierarchy Process) approach to assign weight to the fourteen general system characteristics, and gives the improved formula of VAF. It makes IFPUG method more suitable to these other types of software systems besides the information management system. An example of functional size measurement is given to illustrate the feasibility of this method. And it also illustrates that the fuzzy AHP approach can get a better accuracy of the function point counting, and reduces the deviation. © 2012 IEEE.

The traditional database is designed for the structured data and the complex query. In the environment of the cloud, the scale of data is very large, the data is nonstructured, the request of the data is dynamic, these characteristics raise new challenges for the data's storage and administration, in this context, the NoSQL database comes into being. The article compares and analyzes the general structure of the Cassandra, HBase, MongoDB, the data's distribution mechanism in the cluster, the mechanism of the fault tolerance, their support for the programming model and some relevant technologies, in order to provide some references for selecting or building the NoSQL database solution. © 2012 IEEE.

Nonfunctional property verification is becoming more and more important to computer system. In recent decades, in order to describe not only the system function but also the system performance, researchers in the area of formal methods try to extend Petri net for modelling computer system, and the verification problem becomes the quantitative verification from the qualitative verification. In this paper, we define the reachability graph and present the solution algorithm to reachability graph;then we put forward an algorithm for linear-time temporal logic model checking probabilistic Petri net system;for demonstrating the effectiveness of this algorithm, we run an example in the modelling an verification tool which we developed.
