The reduction of the ripple of driving force is especially required for the practical utilization of linear synchronous motor for rope-less elevator. In this paper, the magnetic region of the linear motor is optimized by using topology optimization techniques (density method and ON/OFF method) in order to reduce the ripple of driving force. The optimal results of both methods are compared, and useful information for the optimal design of linear motor is obtained.

According to electrical output up rating of a permanent magnet motor and request to operate for a large variable speed range, resonance between structural natural vibration and electromagnetic force inside the motor can take place and make noise. This paper describes the mechanism of a resonance between them and noise lowering procedure by frequency shift when they are applied to the reluctance torque largely employed new motor named Permanent magnet Reluctance Motor (PRM).

Healthcare is increasingly becoming a distributed service involving stakeholders and resources who may be physically far from each other. But privacy and security are potential problems. Patient’s data should be available irrespective of their location, but only to authorized person. Not only that, the relationship between the person under observation and other related people, are different and the security and other characteristics concerning the data may also differ accordingly. In this paper we propose a system where an overlay network can be built in an ad hoc basis and links between different entities will be established according to the social relationship between the object person and the person at the other end and the situation of the observed person. Unlike traditional 24-hrs monitoring system, we argued that an ondemand, requirement oriented system will be beneficial for efficient resource utilization, specially in wireless communication.
