this paper discusses the performance evaluation and availability analysis of ammonia synthesis unit of a fertilizer plant. the fertilizer plant is a complex and repairable engineering system comprises of various units viz. shell gasification and carbon recovery, desulphurization, co-shift conversion, decarbonation, nitrogen wash and ammonia synthesis etc. one of the most important functionaries...

We present an analitical study of the dynamical process of the approach to steady state for a driven diffusive system represented by the microemulsion phase of a ternary mixture. The external applied field is given by a “plane Couette”shear flow and the problem is studied within the framework of a time-dependent GinzburgLandau model. A Fokker-Planck equation for the probability distribution of ...

In the present paper, we analyze the effect of varying catastrophic intensity on a limited capacity Markovian queueing system with two identical servers. The time dependent probabilities for the number in the system are obtained. The steady state probabilities and various measures of performance are also provided. Further some important particulars cases are also derived and discussed.

We study the question of existence of steady-state probability distributions for systems perturbed by white noise. We describe a class of nonlinear feedback systems for which an explicit formula for the steady-state probability density can be found. These systems include what has been called monotemperaturic systems in earlier work. We also establish relationships between the steady-state proba...

in this paper, startup performance of upflow anaerobic hybrid reactor and upflow anaerobic sludge blanket reactors in anaerobic treatment of distillery spentwash has been studied under identical conditions of operation. various effluent characteristics like ph, electrical conductivity, chemical oxygen demand, biochemical oxygen demand and total solids and other process parameters like biogas pr...

this paper presents the steady state behavior and maintenance planning of the bleaching system in a paper plant. the paper plant comprises of various systems including feeding, chipping, digesting, washing, bleaching, screening, stock preparation and paper making, etc. one of the most important functionaries of a paper plant, on which quality of paper depends, is the bleaching system, where rem...

In this paper, loss probabilities and steady state probabilities of data packets for an asynchronous transfer mode (ATM) network are investigated under the buffer division and push-out schemes. Data packets are classified in classes k which arrive in Poisson fashion to the service facility and are served with general service rate under buffer division scheme, finite buffer space N is divided in...
