Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure
Advanced Engineering Materials, EarlyView.Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.

Epistemology of modeling and simulation
2013 Winter Simulations Conference (WSC), 2013 While ontology deals with the question of being or existence, epistemology deals with the question of gaining knowledge. This panel addresses the challenge of how we gain knowledge from modeling and simulation.

Introduction to modeling and simulation [PDF]
Proceedings of the 2003 International Conference on Machine Learning and Cybernetics (IEEE Cat. No.03EX693), 2004 Simulation is a powerful tool for the analysis of new system designs, retrofits to existing systems and proposed changes to operating rules. Conducting a valid simulation is both an art and a science. This paper provides an introduction to simulation and modeling and the main concepts underlying simulation. It discusses a number of key issues regarding

Simulation by modeling may be classified into three related methods.1. We may use analog models which obey the same laws as the phenomena we wish to study. Instruments such as network analyzers, slide rules, and electrolytic tanks are examples of devices that are used to make analog models.2. We may use mathematical models to describe phenomena we wish

On Modelling And Simulation of Occupant Models
Building Simulation Conference Proceedings, 2015The selection of modelling and simulation methodologies plays an unprecedented role over the predictive accuracy of occupant behaviour and presence models. In this study, different modelling and simulation formalisms emerging from the literature were introduced to represent occupant's presence and lighting use in BPS tools.

Modeling and simulation of the trawl in fishing simulator
Proceedings of the 15th ACM SIGGRAPH Conference on Virtual-Reality Continuum and Its Applications in Industry - Volume 1, 2016The aim of the present study is to develop a numerical calculation method to accomplish dynamic simulation of the fishing nets in fishing simulator. Fishing nets were modeled as a group of lumped mass points interconnected with springs that have no mass under the uniform flow motion.

MODELLING AND / FOR / BY SIMULATION
Annual Review in Automatic Programming, 1985Abstract Various aspects of the close interconnection of the two tasks ‘Modelling a System’ and ‘Simulating a System’, shall be discussed for continuous systems. Some typical examples from different areas of application will be given in order to provide some insight into this matter.

Validation of simulation models
Journal of Experimental & Theoretical Artificial Intelligence, 2012In philosophy of science, the interest for computational models and simulations has increased heavily during the past decades. Different positions regarding the validity of models have emerged but the views have not succeeded in capturing the diversity of validation methods.
