A simple model of an antagonistic muscle system is developed based on several published physiological observations and is found to be a linear first order approximation to mammalian muscle. The model response is compared to that of the human hand in various tests including impulse response, frequency response, step response and the effect of sliding friction. The results of these tests are used to select the mechanical parameters of the proposed model. The final model simulates many of the observed responses of the human hand when executing motions similar to handwriting. A control scheme is proposed for use with the mechanical model and an electronic simulation of the whole system is conducted using a digital and an analogue computer. Good matches of displacement and acceleration waveforms from human handwriting were produced by the simulation. A discussion of some physiological evidence supporting the proposed control scheme is given. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate

The purpose of this experiment was to implement an alternative mapping realization of the hierarchical abstract simulator on the Intel Multibus 1 microprocessor system. Utilizing three 286/10 single board computers, integration of the M286 monitor with the hierarchical abstract simulator algorithm and execution of the distributed simulator system (DSS) was studied. Seven experiments were done on the DSS showing that the DSS correctly executes the algorithm of the hierarchical abstract simulator. An additional benefit is that parallelism is achieved even without external input: one simulator executes the internal transition function, with other executing the external transition function. This system has demonstrated that the hierarchical abstract simulator concept can be implemented on present-day, available hardware.

Approved for public release, distribution unlimited / The purpose of this thesis is to conduct the research necessary to develop integrated 3D terrain maps capable of supporting an Unmanned Aerial Vehicle Flight Mission Control Support System. In this work, the author has tried to explore the feasibility of exploiting digital topographic maps and further understanding of the digital terrain support available to UAV FMCSS developers. This thesis explores numerous digital terrain data representations and tools available to create digital environments. This work examines and gives a methodology how to find, process, and operate in these environments. To accomplish this, the author explores the more general problem of where to find the data, what tools are available, and how to put the pieces together to create a registered digital environment on a state-of-the-art computer. This work provides a logical construct and design methodology for an analyst to create high fidelity terrain data sets. It functions as a â how toâ manual to help analysts understand which information and tools are available to use for different types of simulation projects.
