Advancement in machining technology of curved surfaces for various engineering applications is increasing. Various methodologies and computer tools have been developed by the manufacturers to improve efficiency of freeform surface machining. Selection of the right sets of cutter path strategies and appropriate cutting conditions is extremely important in ensuring high productivity rate, meeting...

We introduce an evolutionary stochastic-local-search (SLS) algorithm for addressing a generalized version of the so-called 1/V/D/R cutting-stock problem. Cutting-stock problems are encountered often in industrial environments and the ability to address them efficiently usually results in large economic benefits. Traditionally linear-programmingbased techniques have been utilized to address such...

Methods: After considering inclusion and exclusion criteria, cases were divided in to 5 groups. All Women were injected 50 ml of normal saline into umbilical vein immediately after clamping and cutting the cord, in group A without oxytocin, in Group B with 10 units of oxytocin, in group C with 20 unit oxytocin and in group D with 30 unit oxytocin. In group E (control) women were managed conserv...

Optimization of cutting parameters is important to achieve high quality in the machining process, especially where more complex multiple performance optimizations are required. The present investigation focuses on the multiple performance optimizations of machining characteristics of unidirectional glass fiber reinforced plastic (UD-GFRP) composites. The cutting parameters used for the experime...

A high moisture level in the top 10 cm of soil at time of cutting of alfalfa increased the incidence of plant mortality and Fusarium wilt in soil infested with Ditylenchus dipsaci and Fusarium oxysporum f. sp. medicaginis in greenhouse and field microplot studies. Ranger alfalfa, susceptible to both D. dipsaci and F. oxysporum f. sp. medicaginis, was less persistent than Moapa 69 (nematode susc...

Observations are made regarding the influence of cutting speed and friction on cutting force by way of finite element modeling. Simulations are validated by comparison of cutting forces and chip morphologies for the Al6061-T6. Analysis of cutting forces over a wide range of cutting conditions suggests an important role of the secondary shear zone in the decrease of cutting force as a function o...

In this work we present a novel level set-based model for the real-time simulation of soil deformations. A level set defined by a signed distance function and sampled in a regular 3D grid represents and tracks the soil volume under deformation. Moving away from classical 2.5D heightfield representations of soil to a full 3D volume representation allows for improved tracking of cutting tool oper...

We examine the history of cake cutting mechanisms and discuss the efficiency of their allocations. In the case of piecewise uniform preferences, we define a game that in the presence of strategic agents has equilibria that are not dominated by the allocations of any mechanism. We identify that the equilibria of this game coincide with the allocations of an existing cake cutting mechanism.

Packet classification is one of the fundamental techniques required by various network management functionalities. As the state-of-the-art of software packet classification, decision-tree algorithms employ various geometrical cutting schemes to build optimized decision trees. However, existing cutting schemes cannot meet the desired performance on large rulesets because they sacrifice either cl...
