Based on a general methodology using natural co-ordinates, a three-dimensional whole body response model for the articulated human body is presented in this paper. The joints between biomechanical segments are defined by forcing adjacent bodies to share common points and vectors that are used in their definition. A realistic relative range of motion for the body segments is obtained introducing...

Augmented Reality (AR) is the evolution of the concept of Virtual Reality (VR). Its goal is to enhance a person's perception of the surrounding world. AR is a fast growing state of the art technology and a variety of implementation tools thereof exist today. Due to the heterogeneity of available technologies, the choice of the appropriate framework for a mobile application is difficult to make....

When designing controllers with robust performance and stabilization requirements, H-infinity synthesis is a common tool to use. These controllers are often obtained by solving mathematical optimization problems. The controllers that result from these algorithms are typically of very high order, which complicates implementation. Low order controllers are usually desired, since they are consider...

As there are many methods designed for augmented reality, it is still hard to really bring augmented reality application to the real life due to the performance constraint of mobile devices. In this project, I tried to implement certain promising algorithms and explore the possibilities of rich augmented reality application. ESM algorithm is chosen for tracking the clue of the scene together wi...

In order to mitigate climate change, the energy sector undergoes a transformation towards climate-neutral future based on renewable sources. Energy system models generate insights and support decision making for this transformation. face of, e.g., growingly complex important environmental assessments stakeholder structures, considering multiple objectives in these becomes essential realisticall...

This paper is aimed toward the definition of a new exact augmented Lagrangian function for two-sided inequality constrained problems. The distinguishing feature of this augmented Lagrangian function is that it employs only one multiplier for each two-sided constraint. We prove that stationary points, local minimizers and global minimizers of the exact augmented Lagrangian function correspond ex...

Frictional contact is one of the most challenging problems in computational mechanics. Typically, it a tough nonlinear problem often requiring several Newton iterations to converge and causing troubles also solution related linear systems. When modeled with aid Lagrange multipliers, impenetrability condition enforced exactly, but associated Jacobian matrix indefinite needs special treatment for...

We consider global convergence properties of the augmented Lagrangian methods on problems with degenerate constraints, with a special emphasis on mathematical programs with complementarity constraints (MPCC). In the general case, we show convergence to stationary points of the problem under an error bound condition for the feasible set (which is weaker than constraint qualifications), assuming ...

The object of this paper is to study $(epsilon)$-Lorentzian para-Sasakian manifolds. Some typical identities for the curvature tensor and the Ricci tensor of $(epsilon)$-Lorentzian para-Sasakian manifold are investigated. Further, we study globally $phi$-Ricci symmetric and weakly $phi$-Ricci symmetric $(epsilon)$-Lorentzian para-Sasakian manifolds and obtain interesting results.
