Studies of animal behavior are crucial to understanding animal-ecosystem interactions, but require substantial efforts in visual observation or sensor measurement. We investigated how classifying behavioral states of grazing livestock using global positioning data alone depends on the classification approach, the preselection of training data, and the number and type of movement metrics. Positi...

in this paper, we investigate the canonical property of solutions of a system of differentialequations having a singularity and turning point of even order. first, by a replacement, we transform thesystem to the sturm-liouville equation with a turning point. using the asymptotic estimates for a specialfundamental system of solutions of sturm-liouville equation, we study the infinite product rep...

Lubricant and coolant can improve surface roughness in machining. In addition of ecological harms, thermal shock of coolant or lubricant may affect the surface integrity especially on surface residual stresses and micro-crack nucleation. Dry machining is ecologically desirable and it is considered as a necessity for manufacturing enterprises in the recent years. 55Cr3 steel grade is steel with ...

Interactive graphics are an effective way of communication and information delivery, especially for complex domains. However, domain experts are rarely aware of the potentials of interactive visual displays and which interaction principles can be in charge for communication and teaching purposes. In this paper we extend a pattern language for interactive information graphics and present four pa...

This paper deals with the use of computer simulation aiming at more efficient production of the manufacturing system. In our case, the possibilities of use are demonstrated on a particular example from industrial practice. The purpose was to build up a model of the existing short barrel of the gun manufacturing line, and, especially, to propose a solution for increase of productivity, and to fi...

When a non-rotationally symmetric surface with complex shape is machined in diamond turning machine, Fast Tool Servo(FTS) can be an effective means of fabricating non-rotationally symmetric components. But the size of geometric data describing the surface becomes very large because the depth of cut varies in θ direction as the spindle rotates. Since the FTS controller has a limited capacity of ...

High precision applications, such as, semiconductor manufacturing and diamond turning of optical elements require positioning accuracy within nanometers and therefore require very precise motion control of machine tool axes. The frictional behavior at the slides is a result of very complex interaction between the contacting surfaces and lubricants. No accurate quantitative prediction of the fri...
