The GPU has proven to be a powerful processor to compute spring-mass based surgical simulations. It has not previously been shown however, how to effectively implement haptic interaction with a simulation running entirely on the GPU. This paper describes a method to calculate haptic feedback with limited performance cost. It allows easy balancing of the GPU workload between calculations of simu...

The Food Simulator is a haptic interface that presents biting force. A taste of food arises from mixture of chemical, auditory, olfactory and haptic sensation. Haptic sensation while eating is a remained problem in taste display. The Food Simulator generates force to the user’s teeth to display food texture. The device is composed of four linkages. The mechanical configuration of the device is ...

Introduction: One of the important tasks of nurses in intensivecare unit is interpretation of ECG. The use of training simulator isa new paradigm in the age of computers. This study was performedto evaluate the impact of cardiac arrhythmias simulator softwareon nurses’ learning in the subspecialty Vali-Asr Hospital in 2016.Methods: This study was conducted by quasi-experimentalrandomized Salomo...

The purpose of this project is to develop a computer system that accurately simulates natural selection among species in a given environment. If the simulation is accurate towards real-world situations, then observing natural behavior will be significantly easier to manipulate than a natural environment. The Evolution Simulator will incorporate programming AGENTbased simulation techniques, and ...

Peer-to-peer network in general and specifically the Gnutella network suffer from poor search facilities due to their distributed and decentralized nature. Several improvements to the current implementations have been proposed, but the development of new improvements is hampered by the lack of a simple Gnutella simulator to test out algorithms on. The simulator that we developed is easy to use ...

ABSTRACT Little research has been conducted to understand the difference in driving performance between younger-old adults (60-75 years) and older-old adults (76+ years), or simply younger olds and older olds. The main objective of this study was to determine if a minimal increase in road light level (luminance) differently affects the performance of these two distinct age groups. Older adults...

This paper describes the performance of an image capture simulator. The general model underlying the simulator assumes that a) the image capture device contains multiple classes of sensors with different spectral sensitivities and b) that each sensor responds linearly to light intensity over most of its operating range. We place no restrictions on the number of sensor classes, their spectral se...

A mechanism for automatic update of tracking simulator parameters is suggested. A tracking simulator is a simulator, which runs in real time, and which corrects its own behavior (models) by comparing real process measurements to simulator outputs. Typically, a process simulator, no matter if static or dynamic, cannot adapt its behavior to reality, but the tracking simulator has this ability due...
