Hyperelastic constants from a modified hardness test using energy balance obtained from FE-analysis

In order to simplify the hyperelastic characterisation of rubber materials, an extension of the standard hardness test is proposed. A number of indentation depths are chosen for the hardness test and the indentation forces for these depths are recorded. By this modification, hyperelastic constants can be derived from the test, providing more information from the test by a small extra effort. Equiv

Ghosts also cry [Review of the motion picture Volver].

Reviews the film, Volver, directed by Pedro Almodóvar (2006). At the beginning of this extraordinary film, women in a small Spanish town tend to the graves of their departed; at the end, what some would consider a female "ghost" nurses a relative with cancer, as a haunting shot of a wooden door with cracks of light slowly turns dark, reminding us that in the blackness that will engulf us at the en

Establishing Timing Requirements and Control Attributes for Control Loops in Real-Time Systems

Advances in scheduling theory have given designers of control systems greater flexibility over their choice of timing requirements. This could lead to systems becoming more responsive and more maintainable. However, experience has shown that engineers find it difficult to exploit these advantages due to the difficulty in determining the “real” timing requirements of systems and therefore the techn

Collective agreements. A comparative study of Swedish and Vietnamese labour law systems

In recent years, Vietnam has witnessed its economic slowdown. In the labor market, low wages, poor working conditions, violations of labor law are common; labor disputes and strikes increase and these have been negatively affecting workers' lives. Reason for this situation is that the market economy has developed at a higher level; Vietnamese enterprises have become more and more competitive. In t
