In this paper, the residual stress of thermal spray coatings in gas turbine component by curvature method has been studied. The samples and shaft were coated by hard WC-12Co cermets using high velocity oxy fuel (HVOF) after preparation in same conditions. The curvature of coated samples was measured by using of coordinate measurement machine (CMM). The metallurgical and Tribological studies has...

Spray and air–fuel mixing in gasoline direct-injection (GDI) engines play a crucial role combustion emission characteristics. While variety of phenomenological spray models computational fluid dynamics (CFD) simulations have been applied to identify mixture distribution, most research efforts so far were concentrated on single axial-nozzle injectors limited range ambient conditions. Especially,...

IN order to remain competitive in the worldwide market for continuously cast steel, steel producers are finding it increasingly important to implement process control improvements. Through superior production process monitoring and control, producers are improving steel quality and are meeting customers’ requirements for steel size, grade, quantity, and properties at the lowest cost. Computer m...

For effective operation of a selective sprayer with real–time local weed sensing, herbicides must be delivered accurately to weed targets in the field. With a machine vision–based selective spraying system, acquiring sequential images and switching nozzles on and off at the correct locations are critical. An MS Windows–based imaging system was interfaced with a real–time embedded selective spra...

Internet drive-by downloads attacks are the preferred vehicle to infect desktop computers. In this paper, we propose a new URL analysis framework that combines lightweight virtualization and novel modifications to the WINE engine to detect heap spray attacks against applications. In addition, we are able to extract the attack shellcode used to further download other malicious binaries to the vi...

To make paper, machines spray wet pulp on a moving screen and extract the water from it by squeezing it between rollers, before drying it using heat and rolling it on reels as finished product. The water extracted in the squeezing process is removed by a continuous roll of fabric called a felt. There are typically three felts on a paper machine. Felts wear out over time, and therefore must be r...

A rapid compression machine (RCM) has been designed and built for investigating the autoignition characteristics of bio-derived jet and diesel fuels. The RCM has been designed with a particular emphasis on versatility, so that non-volatile fuels may be tested in a premixed gas phase, as a fuel spray, or as an aerosol in an oxidizing bath gas. A blend of these test approaches provides insight in...
