We present an optimal parallel implementation of a meldable priority queue based on the binomial heap data structure. Our main result is an interesting application of the parallel computation of carry bits in a full adder logic to binomial heaps, thus optimizing the parallel time complexity of the Union (often called melding) of two queues. The Union operation as well as Insert, Min, Extract-Mi...
this paper deals with optimal operation of a three-product dividing-wall column (dwc). the main idea is to design a control structure, through a systematic procedure for plantwide control, with an objective to achieve desired product purities with the minimum use of energy. exact local method is used to find the best controlled variables as single measurement or combination of measurements base...
objective in previous studies, the relaxant, anticholinergic (functional antagonism), antihistaminic and its stimulatory effects on b-adrenoceptors of nigella sativa have been demonstrated on guinea pig tracheal chains. in the present study, the relaxant effects of hydro-ethanolic, macerated aqueous (ma) and lipid-free macerated aqueous (lfma) extract of nigella sativa on tracheal chains of gui...
In order to solve the problem that three-phase current of interior permanent magnet synchronous motor (IPMSM) contains 11th and 13th harmonics, a multiple rotating frame transformation (MSRFT)-based harmonic suppression method is established. Firstly, influencing factors harmonics in IPMSM vector control are analyzed, influence mechanism inverter’s dead-time effect flux linkage on described. Se...
This paper presents a framework that allows several independent dataflow analyses which perform optimizations to be composed and applied concurrently. This is done so that every analysis will benefit from the transformations made to the program by all other analyses. Dataflow analyses are mostly used in optimizing compilers, to deduce transformations that can be applied on the original program,...
Most Prolog machines have been based on specialized architectures. Our goal is to start with a general purpose architecture and determine a minimal set of extensions for high performance Prolog execution. We have developed both the architecture and optimizing compiler simultaneously, drawing on results of previous implementations. We nd that most Prolog speciic operations can be done satisfacto...
Many complex networks show signs of modular structure, uncovered by community detection. Although many methods succeed in revealing various partitions, it remains difficult to detect at what scale some partition is significant. This problem shows foremost in multi-resolution methods. We here introduce an efficient method for scanning for resolutions in one such method. Additionally, we introduc...
The energy usage of computer systems is becoming important, especially for portable battery-operated applications and embedded systems. A significant reduction in the energy consumption of a program can be achieved via code optimizations that transform the code to take advantage of the Instruction Set Architecture (ISA) of the target processor. These code optimizations result in significantly s...
