Some Engineering Aspects of the Nicholson-koch Mobile Chipper

A prototype mobile chip harvester has been designed to harvest forest biomass in the form of 1 ogging residuals for use as energy wood. The prototype is presently undergoing developmental tests. Results are encou raging, indicating mechanical feasibility with prospects of working systems within the next several years. Papers presented before ASAE meetings are consldered to be the property ot th...

The Nicholson blowfly experiments: some history and EDA

The renowned Australian entomologist Alexander J. Nicholson carried out a series of experiments in the 1950s with the intent of learning more about a sheep pest, the blowfly. The results presented here are driven by analyses of the data that Nicholson collected. The situation is of special interest because it involves a system that is nonlinear, has time lags and might be described as non-stati...

Numerical Solution of Fractional Wave Equation using Crank-Nicholson Method

In this paper, Crank-Nicholson method for solving fractional wave equation is considered. The stability and consistency of the method are discussed by means of Greschgorin theorem and using the stability matrix analysis. Numerical solutions of some wave fractional partial differential equation models are presented. The results obtained are compared to exact solutions.
