The Pacific Meridional Mode (PMM) impacts tropical sea surface temperature variations, which in turn affect the PMM through excited atmospheric teleconnections. Previous studies linked this loop to Pacific-excited North Oscillation (NPO; second empirical mode of level pressure variability), while a recent study proposed linkage Aleutian low (AL) variability (the first mode). Unraveling their re...

This paper proposes an intelligent approach for dynamic identification of the vehicles. The proposed approach is based on the data-driven identification and uses a high-performance local model network (LMN) for estimation of the vehicle’s longitudinal velocity, lateral acceleration and yaw rate. The proposed LMN requires no pre-defined standard vehicle model and uses measurement data to identif...

recently, hardware sensors are widely used in monitoring and measurement of water quality parameters. constraint of the instrument to measure some water quality parameters such as the 5-day biochemical oxygen demand (bod5), which are time consuming, causes efforts are diverted to the use of software sensors for online prediction of bod5. the main goal of this research is developing an appropria...

a method based on electrical capacitance tomography (ect) and an improved least squares support vector machine (ls-svm) is proposed for void fraction measurement of oil-gas two-phase flow. in the modeling stage, to solve the two problems in ls-svm, pruning skills are employed to make ls-svm sparse and robust; then the real-coded genetic algorithm is introduced to solve the difficult problem of ...

This paper presents and studies the iteration-complexity of two new inexact variants of Rockafellar’s proximal method of multipliers (PMM) for solving convex programming (CP) problems with a finite number of functional inequality constraints. In contrast to the first variant which solves convex quadratic programming (QP) subproblems at every iteration, the second one solves convex constrained q...

control and evaluation are major secrets of an organization's survival.universities, as research and educational organizations, need to be evaluated in order to survive. the results of educational activities encompass a vast spectrum including the graduates, researchers and planners, scientific publications, as well as satisfaction of students, parents, profossors and staff (ramsden, 1996).th...

abstract accurate water measurement and delivery are basic issues in irrigation networks management and performance. in this regard, baffle modules have been considered as appropriate means for delivering almost constant discharge within a specific range of upstream water variation. the structure is meant for low discharge delivery and could be employed in farm irrigation. however, the design c...

This paper presents a mathematical model for the vibration analysis of a three-component piezoelectric force sensor. The cubic theory of weakly nonlinear electroelasticity is applied to the model for describing the electromechanical coupling effect in the piezoelectric sensing elements which operate in thickness-shear and thickness-stretch vibration modes. Hamilton's principle is used to derive...
