Microarray technology demands the development of data mining algorithms for extracting useful and novel patterns. A bicluster of a gene expression dataset is a local pattern such that the genes in the bicluster exhibit similar expression patterns through a subset of conditions. In this study biclusters are detected in two steps. In the first step high quality bicluster seeds are generated using...

The objective of this study was to determine the effects of grasp conditions (types of grasp, grasp width, glove and types of coupling) on maximal pushing force (MPF) and required pinch force (RPF) during snap fit assembly. The results indicated that the type of grasp, the type of coupling and wearing gloves have significant (p<0.05) effects on both MPF and RPF. Regarding the pair wise comparis...

Objects are often movable in the environment and do not have to be grasped from the presented placement. •Pre-grasp interaction can adjust object configuration in the environment to improve the task conditions for the final grasp. •Our video observation surveys the variety of pre-grasp interactions used by people in natural task settings. •The observed pre-grasp interactions can be described by...

OBJECTIVE This study examined the influence ofpencil grasp on handwriting legibility during both short and long writing tasks in 46fourth-grade students who were typically developing. Matched samples were used to controlfor variability. METHOD Regular classroom writing assignments were scoredfor word and letter legibility, and scores were compared using a mixed repeated-measures analysis of v...

We study the output-sensitive computation of all the combinations of edges and concave vertices of a simple polygon that allow an immobilizing grasp with less than four frictionless point contacts. More specifically, if n is the number of edges, and m is the number of concave vertices of the polygon, we show how to compute: • in O(m log m + K) time, all K combinations that allow a form-closure ...

This paper deals with the problem of synthesis of stable grasp by multi-fingered hands. First, a mathematical description of the problem is formulated. The grasp to be synthesized should satisfy equilibrium conditions and unilateral frictional constraints. It should also be stable against disturbances applied to the object. Two types of stability conditions, contact stability and Lyapunov stabi...

In this paper, we describe a solution to the problem of determining the kinematic feasibility of a dextrous hand to grasp a given object at a desired connguration in the two dimensional space. We refer to this problem as kinematic graspability. The kinematic conngu-ration of a grasp is deened in terms of a set of contact pairs between the topological features of the hand and the object. We deri...
