Between 1988 and 1990, serological surveys designed to study local disease prevalence and assess the clinical value of various prenatal screening tests were undertaken at Salmaniya Medical Center in Bahrain. High maternal antibody prevalence (greater than 85%) to cytomegalovirus (CMV), herpes simplex virus (HSV) and rubella was demonstrated, and 28% showed(More)
NURBS were introduced into CAD/CAM systems predominantly for the representation of conventional objects, such as conics and quadrics. Among these, the circle played a critical role in representing a myriad of parts used in the every-day practice. Being the most universally used object, the circle has enjoyed the most popularity in science and engineering.(More)
Biomedical data visualization and modeling rely predominately on manual processing and utilization of voxel- and facet-based homogeneous models. Biological structures are naturally heterogeneous and it is important to incorporate properties, such as material composition, size and shape, into the modeling process. A method to approximate image density data(More)
This paper presents a methodology to repair flawed migrated models that are designed with knowledge-guided NURBS (KGN). Incompatible traditional CAD packages that are based on NURBS technology have been for many years carrying out the exchange of models and data through either neutral file formats (IGES or STEP) or proprietary formats. The exchange process(More)
Integrated high frequency devices require high permittivity dielectric materials with low loss as well as low sintering temperatures. Ceramics with higher permittivity (50<¿r<350) than conventional low temperature co-fired ceramics (5 < ¿r < 10) will drive further miniaturization of embedded capacitor components and resonators. For microwave and mmwave(More)
