Modeling and Simulation Approaches
2018The discussion so far has been limited to relatively narrow abstractions of systems and networks. Such abstractions allow effective assessment and analysis methodologies but do not cover the richness and diversity of realistic organizations, systems and processes.

VECTORIZATION AND ECONOMETRIC MODEL SIMULATION
Computer Science in Economics and Management, 1989Linear analysis of nonlinear models, stochastic simulation, evaluation of forecast errors and optimal control are examples of econometric analysis that require many datasets to be solved for the same model. In this paper, we present an algorithm which demonstrates significant gains in solution speed-up and cost reduction, using vectorization, a ...

PACS Costs: Modelling And Simulation
SPIE Proceedings, 1988The advantages to be expected of full-scale PACS implementation are widely described in the literature. In the decision to introduce such systems, costs will also play an important part. The benefits to be achieved should at least outbalance the costs. In this paper the set-up of a software package for cost assessment is described.

Preparations, models, and simulations
History and Philosophy of the Life Sciences, 2014This paper proposes an outline for a typology of the different forms that scientific objects can take in the life sciences. The first section discusses preparations (or specimens)--a form of scientific object that accompanied the development of modern biology in different guises from the seventeenth century to the present: as anatomical-morphological ...

Electromagnetic Modeling and Simulation
2014This unique book presents simple, easy-to-use, but effective short codes as well as virtual tools that can be used by electrical, electronic, communication, and computer engineers in a broad range of electrical engineering problems. Electromagnetic modeling is essential to the design and modeling of antenna, radar, satellite, medical imaging, and other

3rd IET Professional Development Course on Railway Electrification Infrastructure and Systems, 2005
The design of railway power supplies must account for a wide range of factors such as the performance of the rolling stock, the track alignments, the level of service to be provided as well as basic issues such as the choice of AC or DC and the level of supply security desired.

Reviewing the model-based approach to scientific problem solving from a very general point of view, we observe the following pattern of actions (Figure 3.1.1): Starting with the real world situation, we recognize a problem we want to eliminate or improve.

The chapter describes the design of the speed governing system of 150 MW Francis turbines at a power station. The turbine governing system is vital for the safety and availability of a power plant. The dynamic characteristics of the turbine system are nonlinear and difficult to predict.

In this chapter we present some of the central philosophical issues emerging from the increasingly expansive and sophisticated roles computational modeling is playing in the natural and social sciences. Many of these issues concern the adequacy of more traditional philosophical descriptions of scientific practice and accounts of justification for ...
