The optimization of a pavement management system necessitates the knowledge on the actual values of pavement condition parameters, actual pavement condition improvement as related to the use of various rehabilitation strategies, and scope of pavement deterioration before and after rehabilitation. The data for six pavement condition parameters (bearing capacity, unevenness, rut depth, macro text...

Placing micro-textures on a tool surface can play an anti-wear and friction-reducing role capture impurities improve the tool-chip friction state, thus improving cutting performance of quality workpiece. To ensure processing in micro-texture-coated tool-cutting process, process parameters micro-texture are limited to smaller parameters, which reduces efficiency increases cost. Aiming at this pr...

The objective of this paper is to design and fabricate a micro-cooler to provide integral cooling to electronics or Microelectromechanical Systems (MEMS) type components utilizing current MEMS technologies. A three-port capillary pumped loop (CPL) was analyzed and fabricated from silicon and quartz for this purpose. An analytical study of the device is presented in support of this design. This ...

Surface texturing is an important approach for controlling the tribological behavior of friction pairs used in mechanical and biological engineering. In this study, by utilizing the method of three-dimensional computational fluid dynamics (CFD) simulation, the lubrication model of a friction pair with micro-dimple array was established based on the Navier-Stokes equations. The typical pressure ...

This study investigated the acute and subchronic inflammatory effects of micrometer-size (micro-size) and nanometer-size (nano-size) particles after intratracheal (i.t.) installation in mice. The role of the type of compound, polymorphism, and size of the particles was investigated. Studied compounds were the two micro-size reference quartzes, SRM1878a and DQ12, a micro- and nano-size rutile ti...

In both computer graphics and computer vision, scenes and objects must be represented mathematically in some way. Representations tailored to ease scene acquisition in vision, may be inefficient to render. Likewise, models designed specifically for efficient rendering may be difficult, if not impossible, to capture from cameras. In this thesis, we explore potential graphical models which are bo...

the study area is located at the sanandaj-sirjan zone in the west and north-west of azna and north-east of doroud, iran. the quartz-schists are divided into two main groups: amphibole-quartz schist and garnet-quartz schist. field and microstructural studies show several deformational phases. the d1 episode which is represented by s1, matches with m1 metamprphism and d2 deformation matches with ...

Superheated water has been studied by infrared spectroscopy to examine whether the special ability of liquid water to undergo such a metastable state corresponds to the development of peculiar inter-molecular networking under tension. As the best technique to superheat water is to trap the liquid inside micro-cavities in solids (the so-called "fluid inclusions"), the role of the water-solid int...
