This paper introduces a new compiler optimization called with-loop-folding. It is based on a special loop construct, the withloop, which in the functional language Sac (for Single Assignment C) serves as a versatile vehicle to describe array operations on an elementwise basis. A general mechanism for combining two of these with-loops into a single loop construct is presented. This mechanism con...

Motion control systems have grown in sophistication and precision. However the precision of an entire machine process, for example an assembly operation, involves factors beyond the movement of the controlled mechanism. The initial location of parts prior to handling is subject to a tolerance often much greater than the placement tolerance. The correct position of a part is relative to the fina...

In this paper we study the unrelated parallel machines problem where n independent jobs must be assigned to one out of m parallel machines and the processing time of each job differs from machine to machine. We deal with the objective of the minimisation of the maximum completion time of the jobs, usually referred to as makespan or Cmax. This is a type of assignment problem that has been freque...

Recently, it has been verified that applications of metaheuristics for finding optimal or suboptimal solutions for NP-hard optimisation problems is one of the most promising research fields. Using the ant system metaheuristic, this paper proposes a new design method for state feedback control law which simultaneously achieves the linear quadratic stabilisation and an eigenstructure assignment c...

This study proposes a combination of a fuzzy sliding mode controller (FSMC) with integral-proportion-Derivative switching surface based superconducting magnetic energy storage (SMES) and PID tuned by a multi-objective optimization algorithm to solve the load frequency control in power systems. The goal of design is to improve the dynamic response of power systems after load demand changes. In t...

To facilitate the application of semantics in statistical machine translation, we propose a broad-coverage predicate-argument structure mapping technique using automated resources. Our approach utilizes automatic syntactic and semantic parsers to generate Chinese-English predicate-argument structures. The system produced a many-to-many argument mapping for all PropBank argument types by computi...

Slip power recovery configuration provides an attractive alternative for variable speed drives and generating systems, due to its high-efficiency and low converter rating. The core component is the doubly-excited machine. Firstly, we present a stability analysis of the doubly-excited machine with open loop voltage and open loop current control in the rotor circuit. Possibilities of open loop co...

in this paper, distributed parameter process systems behavior is studied in frequency domain. based on the dominant gain concept that is developed for such studies, a method is presented to control distributed parameter process systems. by using dominant gain concept, the location of open loop zeros, resulted from the time delay parameter in the process model, were changed from the right half p...

one of the questions that has been ignored in letter of credit is a problem of assignment of proceeds in letter of credit that has been discussed generally below the transfer of lc subject, but has differed with it. so in this article, the author has tried to use the words assignment and transfer exactly in their place to clear the existent differences. at first, the writer’s hypothesis was tha...
