Moment generation in wheelchair propulsion

Wheelchair propulsion is a man machine interaction in which chair design and fit affect the relative positions and orientations of the upper extremity relative to the handrim and wheel axle. To understand these relationships better, experimental data were collected in five hand positions from five subjects exerting maximal effort to propel an instrumented wheelchair with its wheel in a locked position. The results of experiments revealed that the progression moment was greater at both initial and terminal propulsion positions and smaller in the mid-propulsion position. The vertical and horizontal force components were directed radially away from the wheel axle posterior to the dead centre position and radially towards the wheel axle anterior to top dead centre. Subsequently, a subject-specific quasi-static model of the upper extremity which maximized wheel progression moment was developed to augment our understanding of experimental measures. Model-predicted trends in progression moments and hand force direction were similar to experiment. Model predictions revealed that the optimal progression moment generation could potentially be affected by an individual's anthropometric parameters, joint strengths and also the direction of force applied by the hand on the handrim. Through wheelchair fitting and training of wheelchair users, it may be possible to improve propulsion technique.     

The mechanical generation of emulsions

Emulsions are complex systems frequently encountered in our daily lives and in most industrial sectors, including the oil industry. An understanding of the mechanisms of emulsion formation is essential both to create them and to treat them. The present work describes the main phenomena that come into play in emulsifying. The break‐up of droplets in either laminar or turbulent flow is discussed, and certain correlations, from which the diameter of the droplets formed can be predicted, are given. The role of surfactants is also examined, as are the typical time scales of the various processes involved.

Next generation actuators leading breakthroughs

Conventional actuators still play the most important roles in motion control of automated machines. However, for advanced machines and instruments with higher performance, the conventional motors seem to be difficult to satisfy the coming sophisticated demands. So, the development of innovative actuators is recognized as one of the most important subjects of the key technology for next generation. Present state of the technology related to innovative actuators is introduced with some examples developed in a national project for new actuators. Essentials to develop a new actuator and to put it to practical use are also commented.     

Tribology in nuclear power generation

A prerequisite for the efficient production of electricity from nuclear power reactors is a high degree of reliability and predictability of performance in engineering components and plant. This can only be achieved if engineering designs are based on sound tribological principles and incorporate the best available data from well planned back-up research and development programmes.The approaches being adopted to tackle the specifically nuclear orientated (ie non-conventional) engineering problems in nuclear power generation are discussed and examples given of successful solutions at all of the various stages of the nuclear fuel cycle ranging from uranium enrichment to power station operation, spent fuel reprocessing and, finally, disposal of waste products. The paper is not intended to be a comprehensive review and does not cover all the areas in great detail.
