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.

Real-time Modeling and Simulation Method of Digital Twin Production Line
IEEE Joint International Information Technology and Artificial Intelligence Conference, 2019In view of the low efficiency of production line modeling method and the poor quality of the production line model, this paper proposes the concept of digital twin production line by analyzing the simulation & modeling of production line and digital twin,

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.
