the efficiency and robustness of reliability methods are two important factors in first order reliability method (form). the conjugate choice control (ccc) and directional chaos control method (dcc) were developed to improve the robustness and efficiency of form formula using the stability transformation method. in this paper, the ccc and dcc methods are applied for reliability analysis of a co...

conclusions the prepared antibody can be used for the development of an elisa kit to assay afm1 in milk and other biological fluids. background aflatoxins are the most extensively studied group of mycotoxins produced by molds, especially the aspergillus group, which are highly toxic to animals and humans. objectives since immunoassay is a simple and rapid method for the analysis of many toxic s...

in this study it has been tried, to compare results and convergence rate of sensitivity analysis and conjugate gradient algorithms to reduce fuel consumption and increasing engine performance by optimizing the timing of opening and closing valves in xu7/l3 engine. in this study, considering the strength and accuracy of simulation gt-power software in researches on the internal combustion engine...

In this paper‎, ‎two extended three-term conjugate gradient methods based on the Liu-Storey ({tt LS})‎ ‎conjugate gradient method are presented to solve unconstrained optimization problems‎. ‎A remarkable property of the proposed methods is that the search direction always satisfies‎ ‎the sufficient descent condition independent of line search method‎, ‎based on eigenvalue analysis‎. ‎The globa...

a classical result of neumann characterizes the groups in which each subgroup has finitely many conjugates only as central-by-finite groups. if x is a class of groups, a group g is said to have x-conjugate classes of subgroups if g/coreg(ng(h)) 2 x for each subgroup h of g. here we study groups which have soluble minimax conjugate classes of subgroups, giving a description in terms of g/z(g). w...

introduction: an effective vaccine against hcv infection is not available. the non-structural protein 3 (ns3) of the virus as an important immunogenic candidate has been utilized in various modules. nanostructured polymers have been recently used for efficient vaccine and drug delivery. the aim of the current study was the synthesis of rns3-g2 conjugate and preliminary evaluation of its immunog...

The fracture behaviors of rocks under dynamic loading are significantly affected by flaws. Understanding regarding this fundamental mechanism flaw-induced fracturing could aid in reducing geohazards deep rock engineering. In study, a series experiments conducted on conjugate flawed white sandstone specimens to study the effect geometric configuration flaws fracturing. results show that geometry...

In this paper, we present a new approach for solving absolute value equation (AVE) whichuse Levenberg-Marquardt method with conjugate subgradient structure. In conjugate subgradientmethods the new direction obtain by combining steepest descent direction and the previous di-rection which may not lead to good numerical results. Therefore, we replace the steepest descentdir...
