A kinetic priority queue is a kinetic data structure which determines the largest element in a collection of continuously changing numbers subject to insertions and deletions. Due to its importance, many different constructions have been suggested in the literature, each with its pros and cons. We propose a simple construction that takes advantage of randomization to achieve optimal locality an...

An efficient design of in situ combustion depends on accurate kinetic modeling of the crude oil oxidation. The kinetic triplet of the oxidation reactions of a heavy oil sample was investigated. Once the kinetic triplet is known, the kinetic equation would be deconvolved. The crude oil sample was obtained from Kuh-E-Mond reservoir, located in the southwest of Iran. The samples were analyzed usin...

Let C denote a set of n mobile clients, each of which follows a continuous trajectory on a weighted tree T . We establish tight bounds on the maximum relative velocity of the 1-centre and 2-centre of C. When each client in C moves with linear motion along a path on T we derive a tight bound of Θ(n) on the complexity of the motion of the 1-centre and corresponding bounds of O(nα(n)) and Ω(n) for...

abstract in this work, the dry reforming of methane was studied using a corona and glow discharge plasma microreactors. a chemical kinetic model was developed to understand the reaction better. the modelization allowed prediction of the reactants conversion according to the energy transfer to the gas (p×τ). the β value is trait of the energy cost, whatever this value was leeser indicated better...

This paper illustrates a new optical flow estimation technique that builds upon a genetic algorithm (GA). First, the current frame is segmented into generic shape regions, using only luminance and color information. For each region, a two-parameter motion model is estimated using a GA. The fittest individuals identified at the end of this step are used to initialize the population of the second...

the toxicity of chlorpyrifos to three iranian populations of two-spotted spider mite, collected from isfahan (isr), yazd (yz) and guilan (gus2) provinces were surveyed using the residual contact vial bioassay. the bioassay results showed that resistance ratios of isr and yz populations were 176.90 and 9.78 fold compared to the gus2 population, respectively. determination of esterase and glutath...

This paper is a continuation of earlier work [6] in which we presented an automatic domain decomposition method for the solution of gas dynamics problems which require a localized resolution of the kinetic scale. The basic idea is to couple the macroscopic hydrodynamics model and the microscopic kinetic model through a buffer zone in which both equations are solved. Discontinuities or sharp gra...

BACKGROUND Optimal turning of critically ill patients is not well established. Kinetic therapy (systematic mechanical rotation of patients with 40 degree turns) may improve pulmonary function more than the improvement in function achieved via the standard of care (turning patients every 2 hours). OBJECTIVE To determine (1) if patients receiving mechanical ventilation who tolerate kinetic ther...
