crops and agricultural products are subject to natural loading during growth. different mechanical forces are also exerted on them during harvest. one product, sugar cane, experiences large shear forces are during harvest. an examination of the crop properties and machine parameters of sugar cane are necessary to develop appropriate cutting tools and the optimization and design of harvesting ma...

Introduction: Silica aerogel is an ultra-lowdensity glass foam used in collector tiles for the capture of particles in low Earth orbit [1] and, recently, for the capture of cometary particles by NASA’s Stardust mission [2]. Reliable and reproducible methods for cutting these and future collector tiles from sample return missions are necessary to enable detailed study of the captured material. T...

Since the cutting tools used in machining process of super alloys are subjected to high cutting forces, accordingly tools life is reduced, therefore improvement in alloys machining and reducing cutting forces to achieve longer tools life is an essential necessity. In this research, the effect of changes in feed rate on cutting forces in machining process of nickel based super alloys is investig...

abstract: nowadays, the non-traditional processes such as “laser, edm and awj” used for cutting high thickness sheet metal. hardox is hard and tough steel alloy and it has many industrialize applications. one best process to cut the hardox is abrasive water jet (awj) cutting.  it can cuts complex shape with high quality and accurate tolerance.  awj cutting offers certain unique benefits such as...

We consider the problem of fair division of a two dimensional heterogeneous good among several agents. Applications include division of land as well as ad space in print and electronic media. Classical cake cutting protocols either consider a one-dimensional resource, or allocate each agent several disconnected pieces. In practice, however, the two dimensional shape of the allotted piece is of ...

The present study was conducted to optimize the green house conditions for Propagation of Stevia rebaudiana cuttings. belonging family Asteraceae, is a native Brazil and Paraguay. Its leaves produced stevioside, an caloric natural sweetener. sweetness stevioside 150 -300 times greater than sucrose. Seeds were very small in size. Production through seeds not beneficial because viable germination...
