Stimulation can be achieved by exposing the body to a transient magnetic field which is generated by passing a high current through a coil over short period of time. By positioning the coil in a specific orientation over the targeted nerve, the magnetic field will create an electric field in the conductive milieu of the body. Induced currents will result from that electric field. If those currents reach a certain amplitude within a specific time period this will cause a neural depolarization. This depolarization will enable us to test and examine the excited nerve providing the necessary data for an effective treatment. In this paper we describe a new design for the stimulating coil with the aim of achieving a more focused magnetic field. This resultant field will excite deep targeted nerves with minimum excitation to the surrounding nerves.","PeriodicalId":177613,"journal":{"name":"Conference Proceedings.

Some algorithms available for computing these transformations are examined for both the first-order and second-order forms of linear time-invariant systems. An important feature of these methods is the simultaneous diagonalization of the controllability/observability Gramians by solving two Lyapunov equations. Different application areas of balanced transformations are highlighted and some limitations and/or problems are pointed out.","PeriodicalId":177613,"journal":{"name":"Conference Proceedings.

A flexible joint is modeled, including Coulomb and static frictions and the model is represented as an ANN. The control strategy is based on a dual loop strategy. An outer load state feedback is used to compute desired load torque and motor state. An inner motor state feedback loop is used to control the motor. Both loops use feedforward compensation of friction. The controllers are represented as an ANN, the system parameters being the weights of the output layer. Parameter identification is achieved using the recursive least squares algorithm. Simulation results show that the proposed controller can suppress vibrations.","PeriodicalId":177613,"journal":{"name":"Conference Proceedings.

The LVM is a new Logic Virtual Machine for Prolog. It adopts one stack policy for all dynamic memory requirements and cooperates with an efficient garbage collection algorithm, Chronological Garbage Collection to recuperate space, not as deliberate garbage collection operation but as a natural activity of the LVM engine to gather useful objects. This algorithm takes advantages of the traditional copying, mark-compact, generational, and incremental garbage collection schemes. In order to determine the improvement of cache performance under our garbage collection algorithm, we developed an emulator to do the trace driven cache simulation. Direct mapped cache and set-associative cache with different cache sizes, block sizes and set associativities are simulated and measured. The objectives of this simulation are to verify and validate our experimental results, and to find important factors which influence the performance of the CGC algorithm.","PeriodicalId":177613,"journal":{"name":"Conference Proceedings.
