We have developed a full quantum transport simulator for p-type Si nanowire field effect transistors based on the k•p Hamiltonian. The NEGF formalism was employed for transport calculation and the self-consistent calculations were performed. We have constructed the Hamiltonian in the modespace, with its size greatly reduced compared to the full Hamiltonian. A computationally demanding problem o...

One of the essential requirements in order to have a realistic surgical simulator is real-time interaction by means of a haptic interface is. In fact, reproducing haptic sensations increases the realism of the simulation. However, the interaction need to be performed in real-time, since a delay between the user action and the system reaction reduces the user immersion. In this paper, we present...

We present our extension for structured fluid simulators and solvers widely used in computer graphics and simulation applications. It is based on storing precalculated fluid simulator states (FSS). The simulation using our extension is based on partial computation with synchronous utilization of pre-calculated fluid simulator states stored on disk device. We have incorporated this concept to re...

This work presents a framework for the design of a haptic-based ultrasound medical diagnostic simulator that can be used for ultrasound training as well as examination. The proposed simulator is composed of a PC workstation, a PHANToMTMhaptic device and a modular software package that allows for visual feedback and kinesthetic interactions between the operator and multi-modality image databases...

As research begins to explore potential nanotechnologies for future post-CMOS integrated systems, modeling and simulation environments must be developed that can accommodate the corresponding problem complexity and nontraditional device characteristics. This paper describes a circuitlevel simulator that can accommodate an important class of nanotechnology devices that are characterized by nonmo...

This paper describes a task repository, a device semantic interface to express device capabilities, and an advice algorithm that suggests the best task-device pair to satisfy a request. The purpose of the task repository is the adaptation of a pervasive environment (Ambient Intelligence) to support natural language applications, such as a natural language interface. The task repository has a pr...

This paper presents a study focused on comparing driving behavior of expert and novice drivers in a mid-range driving simulator with the intention of evaluating the validity of driving simulators for driver training. For the investigation, measurements of performance, psychophysiological measurements, and self-reported user experience under different conditions of driving tracks and driving ses...

Computational protein folding has attracted considerable interest over the years, including molecular simulations and artificial intelligence assisted methods. On other hand, research development of quantum computer hardware software have been thriving recently. In this paper, we report a case study peptide (PSVKMA) based on two-dimensional lattice model, by using both blueqat simulator (called...

We report on the modeling of ultra-small MOS devices using a newly developed full band device simulator. The simulation tool is based on a novel approach, featuring a hybrid Monte-Carlo/Cellular Automata simulation engine self-consistently coupled with a 2D and 3D multi-grid Poisson solver.
