A multivariate logistical model of the system was chosen because the system contains continuous input variables and a singular binary output variable corresponding to an \"all-or-nothing\" nerve action potential. Subsequently, this method was used to quantitatively assess the sensitivity of rapidly adapting afferents in rat hairy skin to the stimulus metrics stress, strain, and their time derivatives. In-vitro experiments involving compressive stimulation of isolated afferents using pseudorandom and non-repeating noise sequences were completed and an analysis of the data was performed using multivariate logistical regression.","PeriodicalId":269364,"journal":{"name":"Proceedings of the IEEE 27th Annual Northeast Bioengineering Conference (Cat.

The goal was to determine the NN with optimal performance in classifying impedance spectra and their corresponding pH values when varying levels of noise were introduced to the original signal. The performance of two linear associative memory NNs (Hebbian and ADALINE) and the backpropagation (BP) NN were evaluated using impedance spectra in the frequency range from 25 Hz-500 kHz as inputs and the pH values as outputs. Results indicate that a BP NN with a single hidden layer and moderate numbers of neurons is an optimal solution for the authors' research.","PeriodicalId":269364,"journal":{"name":"Proceedings of the IEEE 27th Annual Northeast Bioengineering Conference (Cat.

A conventional laparoscopic dissector was fitted with a depth sensor, whose analog output is sampled, processed, and stored using a LabView program on a personal computer. Novice users were tested in simple target approach exercises, using both dominant and non-dominant hands over a seven-day period. Analysis of test data indicated no significant difference in overall precision, but significant differences in approach trajectory, especially during retraction. Data also showed significant improvement in time to complete tasks from day one to day seven. The test fixture was seen to be effective in evaluating a variety of facets of instrument movement and control.","PeriodicalId":269364,"journal":{"name":"Proceedings of the IEEE 27th Annual Northeast Bioengineering Conference (Cat.
