The two fundamental problems in a pattern recognition system are feature extraction (shape measurement) and classification. The problem of extracting a vector of shape measurements from a digital image can be further decomposed into three subproblems. The first is the image segmentation problem, i.e., the separation of objects of interest from their background. The cluster analysis methods disc...

introduction:owing to its favorable radionuclidic characteristics, such as tl/2 = 6.73 day and eβ (max) = 497 kev and ease of its large-scale production using medium flux research reactors, lutetium-177 (177lu) is an attractive radionuclide for various therapeutic applications. no carrier added (nca) 177lu was obtained by thermal neutron bombardment (4×1013n/cm2.s) of 176yb target through 176yb...

Polyvinylidene fluoride/polyvinylpyrrolidone (PVDF/PVP) hollow fiber membranes were fabricated by dry-jet wet-spinning process. The correlated effects of the air gap length and PVP concentration ((1) the air gap length effect at the low and high PVP concentration in the dope solutions, as well as (2) the effect of the PVP concentration at the same air gap length) on the cross-section structure ...

Objectives: The aim of the present study was to establish a simple and reliable method for separation of anteroventral periventricular (AVPV) and arcuate (Arc) nuclei in the rat hypothalamus to evaluate expression of peptide mRNAs in these nuclei using RT-PCR. Methods: Two female Sprague -Dawley rats were perfused transcardially with 10% buffered formalin. Brains were immediately removed and di...

This document describes the simulation and FPGA implementation of the IIP Radiometer Digital IF Section described in [1]. The digital IF processor presented here is a slightly different to that of [1]. The digital IF processor implemented here is illustrated in Figure 1 where there are four distinct sections; namely demultiplex, FS/4 down conversion, filtering and FS/4 up conversion. The struct...

Component infrastructures such as Enterprise JavaBeans [27], Micorosoft’s COM+ [14] and the upcoming CORBA Components [17] have become the de-facto standard for enterprise applications. Reasons for this success are the clean separation of technical and functional concerns, COTS containers (applications servers), and the resulting well-defined programming model and standardization. It is desirab...
