This is a small pattern language for running online trainings. The language starts with an entry pattern ONLINE TRAINING. All other patterns are supporting this pattern and help to make online trainings more alive. Some of the patterns are not exclusive for online uses, for instance PREPARED EXAMPLE or TEST RUN. These patterns could be part of a pattern language for trainings as well. They are ...

A local model of interaction proposed for haptic rendering of rigid body motion is extended to the rigid body manipulation of articulated structures. In the proposed local model, the motion constraints imposed on the user by the articulated structure are rendered through the local dynamics, while those imposed by other virtual objects are rendered through impulsive, penalty, and friction contac...

Discretized representations of deformable objects, based upon simple dynamic point-mass systems, rely upon the propagation of forces between neighbouring elements to produce a global change in the shape of the surface. Attempting to make such a surface rigid produces stii equations that are costly to evaluate with any numerical stability. This paper introduces a new multilevel approach for cont...

Nanoparticle structures observed in aberration-corrected electron microscopes exhibit many types of behavior, some of which are dominated by intrinsic conditions, unrelated to the microscope environment. Some behaviors are clearly driven by the electron beam, however, and the question arises as to whether these are similar to intrinsic mechanisms, useful for understanding nanoscale behavior, or...

The title mol-ecule, C(14)H(18)Cl(4), possesses a crystallographically imposed inversion centre, which coincides with the centre of benzene ring. In the absence of classical inter-molecular inter-actions, van der Waals forces help the mol-ecules to pack in the crystal.

The short nose deformity may arise from multiple etiologies including iatrogenic following rhinoplasty. The weakening of the cartilaginous support and the contractile forces imposed by the healing soft tissue envelope may result in the short nose deformity. The focus of this article is to present the senior author's approach to this nasal deformity.
