INTRODUCTION Dynamic contrast enhanced breast MRI shows a high sensitivity for breast cancer [1]. To avoid respiratory motion artifacts, breast MR images are currently acquired with the patient in a prone position. Supine unilateral breast MRI has several applications including scanning of patients with known claustrophobic sensations, as an aid to breastconserving surgeries and guidance of bre...

This paper presents a simple method based on strain energy density criterion to study the crack initiation angle by finite element method under biaxial loading condition. The crack surface relative displacement method is used to eliminate the calculation of the stress intensity factors which are normally required. The analysis is performed using higher order four node quadrilateral element. The...

In this paper, meshless methods and partition of unity based finite element methods are reviewed. In meshless methods, the approximation is built without the explicit connectivity information between the nodes; moving-least squares approximants and natural neighbor-based interpolants are discussed. The enrichment of the finite element approximation through the partition of unity framework is de...

A dual-band multiple-input-multiple-output (MIMO) antenna system for LTE 700/2300/2500, UMTS2100, GSM 1800/1900 mobile phone applications is presented. The whole system consists of four identical 3-D IFAs (inverted F antenna) loaded with lumped inductors and folded on FR4 cuboids. Without any special designed decoupling structures, the measured isolation among antenna elements is higher than 13...

A C macro-element in four variables is constructed based on a split of a cross polytope into sixteen simplices. The element uses supersplines of degree nine, and provides optimal order approximation of smooth functions.

Knowledge Discovery in Databases (KDD) is the process of extracting novel information and knowledge from large databases. This process consists of many interacting stages performing specific data manipulation and transformation operations with an information flow from one stage onto the next (and often back into previous stages). The process can be very complex and may exhibit much variety in t...
