The purpose of this study is to discuss the role of kappa-carrageenan (?-car) in the drying and swelling of polyacrylamide (PAAm)-?-car composite. The fluorescence intensity of pyranine increased and decreased as drying and swelling time were increased respectively for all samples. The desorption coefficient Dd decreased as ?-car contents were increased for a given temperature during drying. However cooperative diffusion coefficient Ds increased as ?-car contents were increased during swelling at ...

The purpose of this paper is to assess the relationship between foreign direct investment (FDI) and poverty at the macro-pathway in selected developing countries. The contribution to host countries from FDI can take several forms such as the transfer of technology human capital development increased competition in domestic markets and the generation of corporate tax revenues among others. The paper develops a data set and an econometric model to analyse FDI flows and poverty relations at the macro ...

Contingency analysis is one of the most fundamental work an electricity management center operator has to perform regularly. If both bus voltage magnitudes and reactive power flowing on the branches during any type of outages are within the acceptable limits the system is called secure. In this paper we solve the contingency problem using a recently developed local constrained optimization based branch outage problem. The optimization problem resulted from the formulation of branch outage is solved ...

Model order reduction (MOR) techniques are getting more important in large scale computational tasks like large scale electronic circuit simulations. In this paper we present some experimental work on multiprocessor systems for rational Krylov methods. These methods require huge memory and computational power especially in large scale simulations. Therefore these methods are fairly suitable for parallel computing.

Co-array Fortran (CAF) is a small set of extensions to Fortran 90. And also CAF is an emerging model for scalable global address space paralel programming. CAF.s global address space programming model simplifies the development of SPMD paralel programs by shifting the burden for managing the details of communication from developers to compilers. in this study i introduce CAF.s Programming Model provide it.s technical specifications explain CAF.s memory model and PGAS (Partitioned Global Address ...

In hardware implementations of Gaussian Potential Function Neural Networks (GPFNN) deviation from ideal network parameters is inevitable because of the techniques used for parameter storage and implementation of the functions electronically resulting in loss of accuracy. This loss in accuracy can be represented by quantization of the network parameters. In order to predict this effect theoretical approaches are proposed. One-input one-output GPFNN with one hidden layer have been trained as function ...

In this paper a new partial power and rate adaptation scheme for orthogonal frequency division multiplexing (OFDM) systems is proposed in the presence of carrier frequency offset (CFO). The conventional adaptive scheme is shown to be a special case of the partially adaptive scheme technique which enables the resulting non-convex optimization problem solved in a feasible way. It leads to a solution for optimal power adaptation that maximizes the spectral efficiency of an OFDM system using M-ary ...

In this work the effect of hard particle size and blend ratio on the film formation behavior of hard polystyrene (PS) and soft poly(n-butyl acrylate) (PBA) latex blends was studied by means of steady-state fluorescence and UV-visible techniques in conjunction with atomic force microscopy. Three different sets of latexes were synthesized: PBA latex (diameter 97 nm) pyrene (P)-labeled large PS (LgPS
