Sparse matrix reordering is a key issue for the the efficient factorization of sparse symmetric matrices, not only to reduce fill-in and operation count, but also to increase concurrency in the elimination tree, which is essential to achieve high speed-ups when solving the systems on parallel architectures. Most sparse matrix reordering software, when applied to finite-element or finite-volume ...

The finite-element (FE) method is commonly used in biomedical engineering to simulate the behaviour of biological structures because of its ability to model complex shapes in a subject-specific manner. However, generating FE meshes from medical images remains a bottleneck. We present a template-based technique for semi-automatically generating FE meshes which is applicable to prospective studie...

A new non-conforming finite element discretization methodology for second order elliptic partial differential equations involving higher order local absorbing boundary conditions in 2D and 3D is proposed. The novelty of the approach lies in the application of C-continuous finite element spaces, which is the standard discretization of second order operators, to the discretization of boundary dif...

The basic processing element, from PCs to large systems, is rapidly becoming a symmetric multiprocessor (SMP). As a result, the nodes of a parallel computer will often be an SMP. The resulting mixed hardware models (combining shared-memory and distributed memory) provide a challenge to system software developers to provide users with programming models that are portable, understandable, and eff...

telemedicine has changed the way of health care. it is an indispensable tool in the hands of doctors to accelerate and facilitate the process of data interchange. wireless networks consist of small nodes with communications capabilities. development of wireless networks of telemedicine system is highly demanded since these networks promise a wide range of potential applications. in this paper t...

background: axillary nodal spread is an established prognostic factor in breast cancer. axillary nodal dissection and subsequent pathological examination is considered the gold standard technique of assessing the axilla for metastatic disease. a minimum of ten level i axillary nodes are required to be examined before an axillary specimen can be reliably labeled as disease free. this recommendat...

The increasing popularity of using wireless devices to handle routine tasks has increased the demand for incorporating multiple-input-multiple-output (MIMO) technology utilize limited bandwidth efficiently. presence comparatively large space at base station (BS) makes it straightforward exploit MIMO technology’s useful properties. From a mobile handset point view, and handset, complex procedure...
