To avoid the discomfort of direct monitoring, the dyna- mometer system was designed based on 12 string-gauge bridges instrumented on a standard walker frame. The detailed positions of these bridges were determined according to the deformation distri- butions of the walker frame under different directional components of HRV. To adapt the system to quantitative and reliable measurement, a redundant-optimized technique was developed in calibra- tion. The measurement accuracy, nonlinearity. and crosstalk of the designed system were investi- gated, which were better than 1.01%. 2.91%, and 3.19% respectively. Clinical trials were done with 6 paraplegic subjects using the system and one case was given as the example of actual mea- surement. All experiment and clinical trial results show that this method is reliable and practicable.展开更多

The research starts by posing the following questions. Can we claim, in a general perspective of improvement of the quality of life in towns and cities, that the recovery of abandoned historic buildings could be a key-factor in conservation and innovation policies of the historical heart of towns？ What relationship, if any, is there between the adaptive-reuse design of ancient hospitals and the effects of such action, not only in terms of heritage conservation but also in terms of economic and social regeneration of the surrounding context？ The complexity of this issue is addressed by analyzing related cases, relevant for their design solutions and effects, and proposes answers to the opening questions by correlating the main characters of relevant case studies in Europe.展开更多
