‎In this paper‎, ‎we propose a feasible interior-point method for‎ ‎convex quadratic programming over symmetric cones‎. ‎The proposed algorithm relaxes the‎ ‎accuracy requirements in the solution of the Newton equation system‎, ‎by using an inexact Newton direction‎. ‎Furthermore‎, ‎we obtain an‎ ‎acceptable level of error in the inexact algorithm on convex‎ ‎quadratic symmetric cone programmin...

The aim of this paper is to study the local Nusselt number of the symmetrical liquid-liquid jets emitting from a nozzle. Equations obtained from theoretical works are arranged in the form of a computerized model. The validity of this model was tested by the data from an experimental paper [1]. After few adjustments the model predicted the experimental data with a reasonable accuracy. Making...

This paper examines how equity analysts affect corporate liquidity policy and the value of cash. Greater analyst coverage reduces information asymmetry between a firm and outside shareholders and enhances the monitoring process, in turn increasing the value of cash and allowing firms to hold more cash. The cash-to-assets ratio increases by 5.2 percentage points when moving from the bottom analy...

Entities define their own set of rules under which they are willing to collaborate, e.g., interact, share and exchange resources or information with others. Typically, these individual policies differ for different parties. Thus, collaboration requires the resolving of differences and reaching a consensus. This process is generally referred to as policy reconciliation. Current solutions for pol...

The pharmaceutical supply chain is composed of multiple firms interacting to produce and distribute drugs in an uncertain environment. In this work, we develop and validate a multi-agent simulation of the supply chains associated with the pharmaceutical industry. We demonstrate that the operating norms of a particular industry can be accurately represented to create an industry-specific model c...

Portfolios are selected in non-Gaussian contexts to maximize a Cherny and Madan index of acceptability. Analytical gradients are developed for the purpose of optimizing portfolio searches on the unit sphere. It is shown that though an acceptability index is not a preference ordering, many utilities will concur with acceptability maximization. A stylized economy illustrates the advantages from t...

one of the most main head in governments is to achieve the energy for their countries. as the fossil sources are at their ends and also they cause greenhouse emission and environment pollution, shifting to renewable sources of energy is an indispensable alternative for most countries. the sun is the most important renewable energy source. to assessment reachable solar radiation in mashhad from ...
