Objective(s) Developing and validating a simple, efficient, reproducible and economic reversed phase high performance liquid chromatographic (RP-HPLC) method for the quantitative determination of pefloxacin in bulk material, tablets and in human plasma. Materials and Methods A shim-pack CLC-ODS column and a mobile phase constituting acetonitrile: 0.025 M phosphoric acid solution (13:87 v/v, ...

The procedural steps for developing an expert system for designing signals at isolated intersections are described and the most important development issues for each step are discussed. The steps include problem analysis and definition, preliminary prototype specification, knowledge acquisition strategy development, prototype development plan, knowledge extraction, knowledge representation, too...

the aim of this research paper is the introduction of a novel mathematical approach to improvethe accuracy of the results of air pollution dispersion models based on the calibration of input backgroundconcentrations. using the dunkirk area of the city of nottingham in the uk as a case study, an air pollutionmodel in adms-roads was created for developing the mathematical approach. the iterative ...

MR offers a remarkable set of anatomical, functional and metabolic readouts that find extensive use in biomedical research and clinical diagnostics. The nuclear imaging techniques like PET and SPECT as well as optical imaging approaches, however, have a much higher intrinsic sensitivity than MR. This explains why these techniques are presently preferred for molecular imaging applications, in wh...

The present exploratory study aimed to provide a more tangible and comprehensive picture of the construct of investment in language learning through investigating the issue from a quantitative perspective. To this end, the present researchers followed three main phases. First, a hypothesized model of investment in language learning with six components was developed for the Iranian English as a ...

Meta-model based development offers a promising way of managing the complexity of industrial scale software development by describing a system in terms of different ‘views’. These views can then be described as instances of a single meta-model. Such views are usually not disjoint and it is essential that they are shown to be consistent. A weakness of meta-modelling tools is the lack of support ...

Formalizing security requirements has received a significant attention since the 70s. However, a general method for specifying security requirements is still missing. Especially, little work has been presented on specifying and verifying that a given application is a secure resource consumer. The purpose of this work is to set up a methodology for (1)specifying security requirements of service ...

This paper is an introduction to the demonstration sessions for the Precise UML Development Environment (PrUDE). PrUDE is a software V&V platform that integrates in a cost-effective way various rigorous software analysis methodologies.
