One of the problems in software development is the gap between customer requirements and the final product. Especially, if component-oriented programming is taken into consideration, the cost, complexity, and development time should mostly depend on customer requirements. Quality function deployment provides a systematic method for tying design decisions directly to customer wants and needs. Th...

‎artificial neural networks have the advantages such as learning, ‎adaptation‎, ‎fault-tolerance‎, ‎parallelism and generalization‎. ‎this ‎paper is a scrutiny on the application of diverse learning methods‎ ‎in speed of convergence in neural networks‎. ‎for this aim‎, ‎first we ‎introduce a perceptron method based on artificial neural networks‎ ‎which has been applied for solving a non-singula...

in this paper, based on sinh-cosh method and sinh-gordon expansion method,families of solutions of (2+1)-dimensional breaking soliton equation are obtained.these solutions include jacobi elliptic function solution, soliton solution,trigonometric function solution.

The study explores the tradeoff between efforts to benchmark on product-development practices and be customer focused in the implementation of a quality-improvement method. The results of a survey of thirtythree firms' experience with quality function deployment (QFD) reveal that benchmarking on how competitors, peers, or role models develop products facilitates process improvement but hinders ...

housing is the second need after food for human beings. since the housing crisis began with the increase in population, respective governments were forced to construct houses for a large number of families. ignoring the qualitative aspects of these houses has caused social and cultural harm. therefore, designers need to pay more attention to the quality of housing and living environments. the m...

objective: polycystic ovary syndrome (pcos) is one of the most common endocrine disorders that is associated with different metabolic, reproductive and psychological consequences. the main aim of this study was to compare the sexual function and quality of life in women with polycystic ovary syndrome and healthy women. materials and methods: this is a causal-comparative study in which 129 women...

The ERNE project is briefly introduced. The single shot nature of an instrument development project highlights the importance of the concept of process. Useful concepts of process management are reviewed. Trade-off situations and optimisation of diverse requirements are commonplace in space instrument projects. The Quality Function Deployment (QFD) method is discussed as a potential tool for qu...

Two simple methods of using sophisticated statistical techniques to analyse intralaboratory quality control data are described. One method uses a plastic grid to assess the cumulative sum (cusum) graph. An equivalent procedure, which may be carried out by a laboratory computer, gives automated on-line quality control of the Coulter S blood counter. The possible development of simple apparatus t...
