Indiscriminate disposal of beverage cans as waste poses a great threat to the environment, causing flooding, landfill, and blockage drainages, leading land pollution sometimes accident. Hence, there is need design system capable converting these wastes into usable products. In this study, simulation-based analytical for aluminum recycling processing plant was carried out ascertain efficiency re...

In this paper, we discuss the results of recently published analytical concepts for performance evaluation of packetswitched mobile radio networks. For comparison we regard the results of a simulation system (GPRSim), which emulates the GSM General Packet Radio Service (GPRS) in great detail. Our scope is to identify the possible reasons for deviations between analytical and simulation results ...

A new approach to calculate the axially symmetric binary gas flow is proposed Dalton’s law for partial pressures contributed by each species of a binary gas mixture (argon and helium) is incorporated into numerical simulation of rarefied axially symmetric flow inside a rotating cylinder using the time relaxed Monte-Carlo (TRMC) scheme and the direct simulation Monte-Carlo (DSMC) method. The res...

Abstract: A self-timed ring using NULL Convention Logic (NCL) is presented. Analytical method to evaluate the speed of NCL rings has been developed. The analytical predictions are verified by Synopsys simulation. Excellent agreement between the theoretical predictions and simulation results is obtained. The analysis leads to speed optimization of a 24-bit NCL divider to achieve a throughput of ...

Flame bending process is one of the forming processes of steel plates. During this process, plate is formed with heating by gas torch flame followed by controlled cooling along specified paths. Considering simple tools used in the process, it is a popular and economical forming method. At present, this process is manually done on the basis of skilled technician’s experience. Experimental and ...

This paper focuses on the development of simulation-based environment for multi-echelon cyclic planning and optimisation in the product maturity phase. It is based on integration of analytical and simulation techniques. Analytical techniques are used to obtain initial planning decisions under conditions of stochastic demand and lead time, whereas simulation techniques extend these conditions to...

This paper presents an analytical model to evaluate the performance of parallel simulation on distributed computing platforms. The proposed model is formalized by two important time components in parallel and distributed processing: computation time and communication time. A conservative parallel simulation of multistage interconnection networks is used as an example in our analytical model. Pe...
