Clusters for a collection of data could be constructed in various shapes according to the employed clustering method and its parameters. To evaluate the quality of clustering results, a variety of cluster validity indexes have been proposed. This paper presents a new cluster validity index which statistically considers both cohesion and separation of clusters. It presents its properties and shows...
Various approaches have been proposed for clinical protocol development, but few attentions have been paid to the ubiquitous healthcare services. This paper introduces a clinical protocol development methodology which is applicable to ubiquitous healthcare services. The methodology presents a systematic procedure which helps build up a protocol. It focuses on how to elucidate all participants' role...
Microarrays are one of biotechnology products which enable to measure the expression level of thousands of genes simultaneously. It is sometimes crucial to identify some interesting blocks from microarray data for further investigation. Due to the massive volume of data, it is desirable to get assistance of software tools to handle this task. This paper introduces three fuzzy set-based microarray...
