A synchronous-profiling, low-position-cutting, flexible-reel-belt-conveyor, low-loss soybean header was designed to address the problems of a lack harvesting machines supporting soybean-corn strip intercropping, few existing headers, and high loss rate headers. By establishing dynamic model synchronous-profiling cutting device, key structure operation parameters that affect performance synchron...

In this paper, empirical modeling of surface roughness in CO2 laser cutting of stainless steel using was presented. Mathematical modeling was based on using feed forward neural network by exploiting experimental measurements obtained from the Taguchi’s L27 experimental design. The mathematical models of surface roughness was expressed as explicit nonlinear functions of the selected input parame...

cles or the tendons then that’s minimally invasive surgery. If you can do it with two incisions, three incisions, or ten incisions, it doesn’t matter, as long as you don’t cut the muscles or the tendons. Most of the ways that surgeons are doing a single mini incision involve cutting the muscles and cutting the tendons. There’s nothing magic about making one incision or two incisions. However, t...

This paper reports a statistical analysis of the laser wood cutting process. The laser cutting of wood is a multi-factor process and correct combination of the parameters involved is needed to achieve high quality and optimum process efficiency. In this paper a design of experiments and statistical modelling approach is used to investigate the significant process parameters by consideration of ...

The problem of cutting a convex polygon P out of a planar piece of material Q (P is already drawn on Q) with minimum total cutting cost is a well studied problem in computational geometry that has been studied with several variations such as P and Q are convex or non-convex polygons, Q is a circle, and the cuts are line cuts or ray cuts. In this paper, we address this problem without the restri...

The flat glass cutting problem is in the class of NP-Complete problems, thus making an exhaustive search, of every pane in every position, impossible. Instead, an approximate solution is formed, using a combination of software techniques, involving preprocessing of the lists to be cut as well as various feedback processes within the cutting algorithms. Due to practical considerations, the metho...

Old age is associated with poorer movement skill, as indexed by reduced speed and accuracy. Nevertheless, reductions in speed and accuracy can also reflect compensation as well as deficit. We used a manual tracing and a driving task to identify generalized spatial and temporal compensations and deficits associated with old age. In Experiment 1, participants used a hand-held stylus to trace a pa...
