Database Management Systems (DBMS) are at the core of many modern applications, ranging from e-Commerce (e.g. Amazon.COM), web applications (e.g. flickr), online banking, telephony, and even traditional brick-and-mortar retailers. DBMS can be a significant source of delay in these applications, making DBMS the performance bottleneck: users can spend orders of magnitude more time waiting for the...

Cost-effectiveness data is useful for use in priority setting decisions in order to improve the efficiency of resources used. This paper thereby responds to Eckard et al. which addressed the use of cost-effectiveness data in the actual prioritization decisions in the Swedish national clinical guidelines for heart diseases. Based on a set of experiences on the use of economic evaluation in prior...

Virtualization is a fundamental component in cloud computing because it provides numerous guest VM transparent services, such as live migration, high availability, rapid checkpoint, etc. Utilizing virtualization technology to combine real-time operating system (RTOS) and off-the-shelf time-sharing general purpose operating system (GPOS) is attracting much more interest recently. Such combinatio...

To reduce the cost of regression testing, software testers may prioritize their test cases so that those which are more important, by some measure, are run earlier in the regression testing process. One potential goal of such prioritization is to increase a test suite’s rate of fault detection. Previous work reported results of studies that showed that prioritization techniques can significantl...

Context: Prioritization is an essential part of requirements engineering, software release planning and many other software engineering disciplines. Cumulative Voting (CV) is known as a relatively simple method for prioritizing requirements on a ratio scale. Historically, CV has been applied in decision-making in government elections, corporate governance, and forestry. However, CV prioritizati...
