Traditionally 3D interaction techniques (3DITs) are implemented in VR applications in a proprietary way on specific target platforms. Mixing 3DIT specific code with application code neither allows for reusability in other applications nor for exchanging 3DITs in a comfortable and flexible way. We propose an additional system software layer called Virtual Environment Interaction Technique Abstra...

Physical layer security is an emerging security area that achieves perfect secrecy data transmission between intended network nodes, while malicious nodes that eavesdrop the communication obtain zero information. The so-called secrecy capacity can be improved using friendly jammers that introduce extra interference to the eavesdroppers. We investigate the interaction between the source that tra...

Résumé : Nous avons mesuré la fréquence de formation de panaches dans une expérience de convection thermique à Pr >>1. Comme la viscosité du fluide utilisé varie fortement avec la température, les couches limites chaude et froide ont différentes épaisseurs et viscosités. Ceci entraîne des fréquences différentes pour ces couches. Il semblerait qu’il y ait une interaction directe entre les couche...

Preamble Interaction of shock waves with turbulent boundary layers is important in many aerospace applications. Examples in external aerodynamics include control surfaces, wing body junctions, and multi-body aerodynamics. In high-speed propulsion systems, shock-boundary layer interaction (SBLI) can occur in intakes, supersonic combustion chambers and nozzles. Computational fluid dynamics (CFD) ...

One of the claimed benefits of embodied interaction is that it is an intuitive form of human–computer interaction. While this claim seems to be widely accepted, few studies explore the underlying cognitive mechanisms of intuition in the context of tangible and embedded interaction design. What is intuitive interaction? What makes an interface intuitive to use? We explore these questions in the ...

nowadays, atomic force microscope is considered as a useful tool in the determination of intermolecular forces and surface topography with the resolution of nanometers. in this kind of microscope, micro cantilever is considered as the heart of the microscope and is used as a measuring tool.  this paper is aimed towards investigating the behavior of a piezoelectric micro cantilever with a triang...

A. Panas and J.-P. Pantouvakis · Multi-attribute regression analysis for concrete pavement... · pp 289-295 INTRODUCTION Concrete pavement layering is a process that requires the combination of laborand machine-intensive operations. As such, the implications and the interactions of the affecting factors pose a significant research interest, given that published productivity or cost data are scar...

Cylindrical structures in a group are frequently seen on land and in the ocean. Mutual flow interaction between the structures makes the wake very excited or tranquil depending on the spacing between the structures. The excited wake-enhancing forces in some cases cause a catastrophic failure of the structures. This paper presents results of an experimental investigation of Strouhal number (St),...

Numerical modeling is a critical tool to the U.S. Department of Energy for evaluating the environmental impact of remediation strategies for subsurface legacy waste sites. Unfortunately, the physical and chemical complexity of many sites overwhelms the capabilities of even most state of the art groundwater models. Of particular concern is the representation of highly-heterogeneous stratified ro...

We present the modelling of a monitoring system which provides nighttime care by detecting situations of concern and therapeutic interventions as the core technological component within an Ambient Assisted Living project. The modelling of processes and interactions allows early detection of problems in the strategy to be implemented through simulation and verification.
