چکیده
Films of pure poly(vinyl alcohol) (PVA) and samples doped with dierent concentrations of heptahydrated ferrous sulphate were prepared using a casting method. Mechanical and relaxation properties were measured before and after irradiation. The modulus of elasticity, yield strength, tensile strength ductility and relaxation time were produced from true stress±true strain and stress relaxation measurements. The measured parameters were found to be dependent on both FeSO4 concentration and on -doses. A cyclic eect occurs. # 1999 Elsevier Science Ltd. All rights reserved.

Towards a scheduling and timing analysis solution for integrated modular avionic systems
Timing analysis is a collection of mathematically based techniques that enable a system, together with its software, to be analysed off-line without the need for system execution. The result of applying the analysis, is a set of guarantees regarding the worst-case behaviour of the system – under normal system operation, these worst-case guarantees will be met at run-time. The guarantees include...

Primal-dual affine-scaling methods have recently been extended from linear programming to semidefinite programming. We show how to analyze these methods in the framework of potential reduction algorithms. The analysis suggests implementable variants of the methods as 'long step predictor-corrector' algorithms, where the step length is determined by the potential function. A numerical comparison...

This paper describes the use of fuzzy logic techniques to control the speed of a three-phase induction motor. The use of Matlab/Simulink and fuzzyTECH MCU96 as software development tools for system design is emphasised. Hardware implementation is based on a standard 16/32-bit microcontroller, without the need of any additional components for the fuzzy logic controller. The system performance is...

متن کاملPerformance of the Hough transform on a distributed memory multiprocessor
The Hough transform is a projection-based transform which can be used to detect shapes in images. One of the disadvantages of the transform is its requirement for large amounts of computing power. Parallel machines have given programmers the potential for incredible computing power. To obtain maximum performance from parallel machines, parallel algorithms should be designed to reflect the archi...
