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...

High speed machining (HSM) may produces parts with substantially higher fatigue strength; increased subsurface micro-hardness and plastic deformation, mostly due to the ploughing of the round cutting tool edge associated with induced stresses, and can have far more superior surface properties than surfaces generated by grinding and polishing. Cutting edge roundness may induce stress and tempera...

This experimental workanalysis the influence of cutting conditions on surface roughness of EN-8during machining by CNC turning. Analysis of variance (ANOVA) is employed to investigate the influence of cutting speed, feed rate, and depth of cut and coolant type on surface roughness height Ra. The influence of the interaction of cutting speed, feed rate, depth of cut and coolant type on surface r...

Maceration and evening-cutting are 2 forage management techniques that have independently improved forage quality and nutrient utilization in ruminants, but have not been evaluated in combination. Using a dual-flow continuous culture fermenter system, this preliminary study was designed to evaluate the individual and combined effects of time of cutting and maceration on in vitro ruminal digesti...

The quality of a machined surface is becoming more and more important to justify the increasing demands of sophisticated component performance, longevity, and reliability. Usually, any machining operation leaves its own characteristic evidence on the machined surface in the form of finely spaced micro irregularities (surface roughness) left by the associated indeterministic characteristics of t...

BACKGROUND AND OBJECTIVES After being encouraged to change the technique for opening the vaginal cuff during robotic surgery, this study was performed to determine the correlation between vaginal cuff complications and electrosurgical techniques. METHODS The study group consisted of patients who had their vaginal cuffs opened with a cutting current compared to the group of patients having the...

We present effective computational techniques for solving nonconvex quadratic programs with box constraints (BoxQP). We first observe that cutting planes obtained from the Boolean Quadric Polytope (BQP) are computationally effective at reducing the optimality gap of BoxQP. We next show that the Chvátal-Gomory closure of the BQP is given by the odd-cycle inequalities even when the underlying gra...

Adige S.p.A. is a world leader company in projecting, producing and selling lasertube cutting systems. Two different systems are available, one based on fusion and the other on oxidation of the material that has to be cut. Both these techniques require the presence of a laser beam well focalised on the material and an assistance gas stream, used to eject the melted material. Until now paths for...

We study the monotonicity properties of solutions in the classic problem of fair cake-cutting — dividing a heterogeneous resource among agents with different preferences. Resourceand population-monotonicity relate to scenarios where the cake, or the number of participants who divide the cake, changes. It is required that the utility of all participants change in the same direction: either all o...

Streamlines, contour lines, vector plots, and volume slices (cutting planes) are commonly used for flow visualization. These techniques are sometimes referred to as instantaneous flow visualization techniques because calculations are based on an instant of the flow field in time. Although instantaneous flow visualization techniques are effective for depicting phenomena in steady flows, they som...
