Recent Design Optimization Methods for Energy-Efficient Electric Motors and Derived Requirements for a New Improved Method—Part 2

open access: yesProceedings, 2018
Designing energy-efficient electric motor is a task where multiple goals have to be achieved at once. To find the best design possible, different approaches have been developed.

A data-driven model for Fennoscandian wildfire danger [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2023
Wildfires are recurrent natural hazards that affect terrestrial ecosystems, the carbon cycle, climate and society. They are typically hard to predict, as their exact location and occurrence are driven by a variety of factors.

Physical Modelling in MvStudium

open access: yesSNE Simulation Notes Europe, 2012
In this paper, we describe “physical” modeling technology in MvStudium that is a graphical environment for modeling and simulation of complex dynamic systems. MvStudium.6 modeling language (MVL) is based on open hybrid automata or Behavior-Charts (for short BCharts), functional diagrams, and supports object-oriented modeling. B-Chart is an extension of

Physical modelling in biomechanics [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2003
Physical models, like mathematical models, are useful tools in biomechanical research. Physical models enable investigators to explore parameter space in a way that is not possible using a comparative approach with living organisms: parameters can be varied one at a time to measure the performance consequences of each, while values and combinations not

On the Concept of Model in Physics

open access: yesThe Educational Review, USA, 2023
The concept of model is the basis for theoretical and experimental research in physics. A model is defined as an application of physical theories to the description of a physical system. As a premise to the introduction of models, physical theories are defined as mathematical frameworks with a hypothetical-deductive structure, provided with a mapping ...
