Genetic programming was used to find out a mathematical model for drafting force from drafting process parameters on the drawing frame, which fits the experimental data as much as possible. the study used rayon fibers as the raw material in the mini-draw frame. the process parameters on the draw frame such as front roller speed, front roller draft, back roller speed and back roller draft as variables were investigated. the paper used the principle that there is linear relationship between drafting force and deformation from the strain gauges in the sensor. the data obtained from online measurement device was used for training and testing on the genetic programming. A comparison between experimental and predicted data was done. the results show very good agreement between the experimental and predicted values. Furthermore, this article shows that genetic programming can provide further use for setting up the machine process parameters without requiring an expert in the field.

programming support for multi-threaded applications on embedded microcontroller platforms has attracted a considerable amount of research attention in the recent years. this paper is focused on this problem, and presents UnStacked C, a source-to-source transformation that can translate multithreaded programs into stackless continuations. the transformation can support legacy code by not requiring any changes to application code, and only modifications to the underlying threading library. We describe the details of UnStacked C in the context of the TinyOS operating system for wireless sensor network applications. We present a modified implementation of the TOSthreads library for TinyOS, and show how existing applications programmed using TOSthreads can be automatically transformed to use stackless threads with only modifications in the build process. By eliminating the need to allocate individual thread stacks and by supporting lazy thread preemption, UnStacked C enables a considerable saving of memory used and power consumed, respectively.

In this paper, a constraint shifting combined homotopy method for solving multi-objective programming problems with both equality and inequality constraints is presented. It does not need the starting point to be an interior point or a feasible point and hence is convenient to use. Under some assumptions, the existence and convergence of a smooth path to an efficient solution are proven. Simple numerical results are given. (C) 2011 Elsevier B.V. All rights reserved.

First, we present a novel approach to an abstract preference-based argumentation framework (an abstract PAF), which generalizes Dung's abstract argumentation framework (AF) to deal with additional preferences over a set of arguments. In our formalism, the semantics of such a PAF is given as P-extensions that are selected from extensions of acceptability semantics by taking into account such preferences. Second, using a prioritized logic program (PLP) capable of representing priority information along with integrity constraints, the proposed method defines the non-abstract preference-based argumentation framework (the non-abstract PAF) translated from a PLP, whose semantics is also given by P-extensions instantiating those of an abstract one. Finally we show the interesting result that, P-extensions of such a non-abstract PAF under stable semantics capture preferred answer sets of a PLP, which ensures the advantages as well as the correctness of our approach.
