Multi-core processor architectures can have significant performance advantage over traditional single core designs, which are limited by power and processor complexity. Predictions based on Moore's Law state that a processor chip may accommodate thousands of cores in 5-10 years. Can software scale with the number of cores and achieve the performance potential? This paper uses two OLTP (online transaction...
Frequent item mining has been extensively used in association rules mining. The goal of frequent itemset mining is to discover all the itemsets whose supports in the database exceed a user-specified threshold. However, it often generates a large number of candidate itemset, which reduce the effectiveness of the mining algorithms. Constraint-based mining enables users to provide restraints on mining...
CPU scheduler is a very important subsystem which affects system throughput, interactivity and fairness. The development of Linux kernel is relatively fast-paced. By now, many CPU schedulers have been designed by researchers, hobbyists and kernel hackers. It is necessary to accurately compare and analyze different characteristics among these schedulers, so as to understand and design better CPU schedulers...
This paper presents Improved Mountain Clustering (IMC) based medical image segmentation. Proposed technique is a more powerful approach for X-Ray image based diagnosing diseases like lung cancer and tuberculosis. The IMC based segmentation approach was applied on lung X-Ray images and compared with some existing techniques such as K-Means and FCM based segmentation approaches. The performance of all...
