the objective of this study is to examine the effect of mispricing on firm’s investment behavior and capital structure. it also tests the role of the level of financial constraints in the relationship between mispricing , investment and capital structure. using data of 110 firms of tehran stock exchang from 1384-1389, results indicated that mispricing has negative impact to firms investment. ho...

nowadays urban sanitary landfill compatible with environmental principles and in line with sustainable development is a necessity. in this paper for the purpose of determining appropriate sanitary landfill sites in kohgilooye & boyerahmad province, , many data layers were used including: slope, land cover, distance to main roads, distance to cities & villages, geology, surface water network, di...

Object SLAM introduces the concept of objects into Simultaneous Localization and Mapping (SLAM) helps understand indoor scenes for mobile robots object-level interactive applications. The state-of-art object systems face challenges such as partial observations, occlusions, unobservable problems, limiting mapping accuracy robustness. This letter proposes a novel monocular Semantic (SO-SLAM) syst...

this study focuses on the optimization of the plane structure. sequential quadratic programming (sqp) will be utilized, which is one of the most efficient methods for solving nonlinearly constrained optimization problems. a new formulation for the second order sensitivity analysis of the two-dimensional finite element will be developed. all the second order required derivatives will be calculat...

‎In this paper we consider the minimization of a positive semidefinite quadratic form‎, ‎having a singular corresponding matrix $H$‎. ‎We state the dual formulation of the original problem and treat both problems only using the vectors $x in mathcal{N}(H)^perp$ instead of the classical approach of convex optimization techniques such as the null space method‎. ‎Given this approach and based on t...

Discovering and extracting new image features pertaining to scene geometry is important to 3D reconstruction and scene understanding. Examples include the classical vanishing points observed in a centric camera and the recent coplanar common points (CCPs) in a crossed-slit camera [21,17]. A CCP is a point in the image plane corresponding to the intersection of the projections of all lines lying...

A new constraint-handling method based on Pareto-optimality concept for multiobjective multi-constraint design optimization problems has been proposed. The proposed method does not need any constants to be tuned for constraint handling. In addition, the present method does not use weighted-sum of constraints and thus does not need tuning of weight coefficients and is efficient even when the amo...
