A main goal of surgical simulators is the creation of virtual training environments for prospective surgeons. Thus, students can rehearse the various steps of surgical procedures on a computer system without any risk to the patient. One main condition for realistic training is the simulated interaction with virtual medical devices, such as endoscopic instruments. In particular, the virtual defo...

Background and Objectives: Virtual inertia control, as a component of a virtual synchronous generator, is used for the implementation of synchronous generator behaviour in microgrids. In microgrids that include high-capacity distributed generation resources, in addition to virtual inertia, virtual damping can also lead to improvement of frequency stability of the microgrid. The purpose of the c...

It is often said that music affects the impression of our environment and also our behavior. The author’s group previously investigated the effect of music on the performance and impression in the virtual environmental context of video games; racing games and Pachi-slot games (slot-machine type games). The results commonly showed that the “no music” condition provided the best performances, and...

Systematic analysis of 8 B Coulomb dissociation with the Asymptotic Normal-ization Coefficient (ANC) method is proposed to determine the astrophysical factor S 17 (0) accurately. An important advantage of the analysis is that uncertainties of the extracted S 17 (0) coming from the use of the ANC method can quantitatively be evaluated, in contrast to previous analyses using the Virtual Pho-ton T...

We present a complete calculation of the photon + 1 jet rate in e+e− annihilation up to O(ααs). Although formally of next-to-leading order in perturbation theory, this calculation contains several ingredients appropriate to a next-to-next-to-leading order calculation of jet observables. In particular, we describe a generalization of the commonly used phase space slicing method to isolate the si...

We report on a recent calculation of the two-loop virtual QCD corrections to the W boson pair production in the quark-anti-quark-annihilation channel in the limit where all kinematical invariants are large compared to the mass of the W boson. Our result is exact up to terms suppressed by powers of the W boson mass. The infrared pole structure is in agreement with the prediction of Catani’s gene...

In the art field, the modelling of the symbolic forms through the computer programming and the calculated simulation seems to be a revolution for the state and the status of the representation. How is it made and where is it situated? By effect how to situate and define it, from real to virtual, from mimetism to abstraction, etc? And what is the nature of this new kind of artifice, produced by ...

In this paper, we propose a method of estimating camera parameters for annotating 3D virtual objects with a wearable vision system. The proposed method tracks natural feature points using a doubled color histogram matching and template matching. The model-view matrix calculation method consists of three algorithms for PnP problems and uses each algorithm selectively. The experimental system usi...

We review the status of the calculation of next-to-next-to-leading order corrections to large angle Bhabha scattering in pure QED. After discussing the electron-loop and photonic corrections, we focus on the recently calculated two-loop virtual corrections involving a heavy-flavor fermion loop. We conclude by assessing the numerical impact of these corrections on the Bhabha scattering cross sec...
