This paper derives the long-run marginal timber and sawing cost of producing lumber from a dual linear programming framework. A computational accounting procedure is suggested and compared with a recently designed procedure in industrial use. To be useful, the calculated cost figures should be approximately constant over a nontrivial interval of sales volumes. The preliminary results of a case ...

Industrial Research Limited (IRL) has engaged in world leading research in the area of automated beef processing. Two innovative applications of automation are beef belly ripping and beef brisket sawing. The challenges faced in these applications, the methods used to meet them and the results achieved are described.

A framework is brieey introduced, which supports the comparison of Neural Networks and Evolutionary Algorithms. This framework, called \Adaptive Sampling", was used for the design of two incomplete 3-SAT methods. The rst one is based on the Neural Network approach, and the second method mixes general features of Neural Networks and Evolutionary Algorithms (EAs). These methods have been tested a...

The performance of complex polyrhythms-rhythms where the left and right hand move at different rates-is usually the province of highly trained individuals. However, studies in which hand movement is guided haptically show that even novices can perform polyrhythms with no or only brief training. In this study, we investigated whether novices are able to tap with one hand by matching different ra...

The paper deals with the drive options of mechanical presses and their influence on energy efficiency. Although main focus is efficiency, we also emphasize design operational issues. press machine divided into two separate sections – side side. its efficiency described using an balance formula. We quantify for 80 MN forging press. describe eight different types drives from a typical flywheel to...

The loss of water from hardened concrete (stored in unsaturated air) causes drying shrinkage. Shrinkage of hardened concrete is influenced by various factors in a similar manner to creep under drying conditions. High cementitious materials content, particularly fine particles will reduce bleeding, but increase long term drying shrinkage. (The time of sawing the joints for induced cracking is no...

Abstract The subject of this paper is the analysis influence laser cutting oak wood on its drying process. research was comparison process and quality dried in samples cut by classical technology (sawing) with use laser. carried out two sets which were subjected to an identical Continuous moisture loss final attained, gradients before after drying, internal tensions monitored means fork test cu...
