Physical Review B (Condensed Matter), 1994
We present ab initio quantum-mechanical molecular-dynamics simulations of the liquid-metal--amorphous-semiconductor transition in Ge. Our simulations are based on (a) finite-temperature density-functional theory of the one-electron states, (b) exact ...

Simulator Sickness in an Army Simulator
Occupational Medicine, 1990Simulator sickness describes a symptom reported by aircrew during or after flight simulator training. Some features are common to motion sickness but others, which are unusual during real flight, are believed to result specifically from the simulator environment.

To Simulate or not to Simulate
2008Publisher Summary Simulation can take all forms, from discussing a case study to the use of standardized patients to using low- and high-fidelity simulators. Essential to their effective use are educational objectives. Without these educational objectives, neither faculty nor students will know what they are supposed to learn using these tools ...

Simulation, Gaming, and the Simulative [PDF]
Simulation & Gaming, 1999 This article examines the dominance of media-effects studies in communications scholarship and compares the study of communications with the study of simulations and games. The author draws parallels between the two fields of study and discusses the future research agenda for the study of simulations and games.

To simulate or not to simulate
ITSC 2001. 2001 IEEE Intelligent Transportation Systems. Proceedings (Cat. No.01TH8585), 2002A simple decision analysis framework is used to illustrate the key factors to consider in deciding whether or not to use microsimulation to estimate the effects of transportation projects. Microsimulation is useful if it (1) results in implementation of a worthwhile project that would not have been implemented without the simulation or (2) prevents ...

AirSim: High-Fidelity Visual and Physical Simulation for Autonomous Vehicles
International Symposium on Field and Service Robotics, 2017Developing and testing algorithms for autonomous vehicles in real world is an expensive and time consuming process. Also, in order to utilize recent advances in machine intelligence and deep learning we need to collect a large amount of annotated ...

To simulate or not to simulate…
1992Many neural network structures provide a regularity which allows for efficient implementation in hardware devices. However, the performance of these designs is often limited by other factors to levels which fall well short of those expected. The paper discusses a number of these factors and indicates characteristics which make problems more or less ...

DISSIPATIVE PARTICLE DYNAMICS : BRIDGING THE GAP BETWEEN ATOMISTIC AND MESOSCOPIC SIMULATION
, 1997We critically review dissipative particle dynamics (DPD) as a mesoscopic simulation method. We have established useful parameter ranges for simulations, and have made a link between these parameters and χ-parameters in Flory-Huggins-type models.

SYNOPTIC ABSTRACTThe principal shortcoming of simulated annealing (SA) is that it takes too much computer time. We present a few “swindling” ideas for speeding up SA by simulating its action on a problem. The increase in speed is attained at the cost of decreasing generality — the methods all require the use of problem-specific information.

First-principles simulation: ideas, illustrations and the CASTEP code
, 2002First-principles simulation, meaning density-functional theory calculations with plane waves and pseudopotentials, has become a prized technique in condensed-matter theory.
