Energy saving is very important for economical and cost effective operation of the facility. In boilers, steam is produced for various process, utility and instrumental applications. It is very important to operate the boiler with proper operating conditions. The parameters like level of feed water, steam temperature and flow of steam need to be optimized. Various studies are carried out on opt...

Multi-representation reasoning processes often show a variety of reasoning paths that can be followed. To analyse such reasoning processes with special attention for differences between individuals, it is required (1) to obtain an overview of the variety of possibilities and (2) to address navigation and control within the reasoning process. This paper presents a simulation model and analysis f...

The development of new design concepts for ship bridges on modern offshore vessels is a considerable challenge for engineering and design professions. Such ships perform advanced missions in extreme environmental conditions that are very different to those in which most design processes take place. Although site visits can help narrow this gap, such opportunities are limited by both funding and...

This paper presents a model for the simulation of the impact of projectiles of high kinetic energy on light-weight ceramic/metal armours. The work was financed jointly by the Defence Ministries of Spain, Italy, Holland and Denmark as part of a project between nations for the development of tools for the design of this type of armour. The model consists of a series of differential equations inco...

A collection of software tools for analysis of timed Petri nets, known as TPN–tools, developed over a number of years, has been extended by a simulation tool, TPNsim. The paper gives a brief characterization of TPNsim, and discusses some implementation aspects in greater detail.

A 3-dimensional computer model of sustained bipedal walking is presented. It is intended be used as a development tool for walking controllers. The direct dynamic simulation has 8 segments, 19 degrees of freedom and is driven by prescribed joint moment and stiffness trajectories. Limited feedback in the form of a proportional-derivative controller provides upper body stability and allows walkin...

optimization through simulation is considered anefficient tool in dealing with optimization problems. it’s a tool that iscapable to cover real world problems to a much more complete way than the otheroptimization tools. the problem of this tool is the necessity of heavyprocessing computations. this problem is caused not only since the simulationprocess is time consuming, but the objective funct...

in this research, our attempt is to monitor tool wear through the chip formations, forces, and temperature of edge of drill while drilling in superalloy plate to optimizes effective parameters, which lead to facilitate machining process to, improved tool life, and enhance the productivity. in this study, inconel718 superalloy material, and cemented coated carbide tool was selected for investiga...

In this article effects of friction stir welding (FSW) tool rotational and traverse speeds were studied on heat generation and temperature distribution in welding zone of AA1100 aluminum alloy and A441 AISI joint. Computational fluid dynamics method was used to simulate the process with commercial CFD Fluent 6.4 package. To enhance the accuracy of simulation in this Study, the welding line that...
