Using the price for recycling used home appliances as a variable in the decision-making process, this paper studies the pricing decision-making process of the home appliances enterprises when a wholesale and retail price for the green home appliances have already been determined in advance. Considering the influences of the effective recycle behavior of the used home appliances to the whole sup...

Abstraet--A budget model is developed to predict the long-term response of a lake to changes in its phosphorus loading. This model computes total phosphorus and hypolimnetic oxygen concentrations, taking sediment-water interactions into account. The lake is treated as two segments: the water and a surface sediment layer. A total phosphorus budget for the water accounts for inputs due to externa...

This paper presents computer-based design and analysis of control systems for centrifugal compressors when the operating fluid is supercritical CO2. It reports a non-linear dynamic model including a main forward compression line and two different configurations for the recycle antisurge line. Disturbance scenarios are proposed for testing the configurations and performance indicators are sugges...

A great effort to recycle batteries has been performed in the last two decades. During this period new directives have been published specially in Europe. The aim of this paper is to review the current status of technologies applied to recycle portable batteries, e.g. lead acid will not be described here. Essentially, this paper presents the current status of the technologies involved in the co...

Exponential polynomials arising in transfer functions of chemical processes with recycle and time-delay preclude the use of standar control technics designed for free-delay systems. In this work a simple and effective methodology to derive an approximate discrete-time model free of delay of a continuous timedelayed systems describing recycle and dead-time processes is proposed. The method is ba...

Engineering problems frequently require solving a sequence of dual linear systems. This paper introduces recycling BiCG, that recycles the Krylov subspace from one pair of linear systems to the next pair. Augmented bi-Lanczos algorithm and modified two-term recurrence are developed for using the recycle space. Recycle space is built from the approximate invariant subspace corresponding to eigen...
