Aggregates constitute major part of the pavement structure. The engineering properties of the aggregates, as well as its shape (i.e. form and angularity) and texture, substantially affect the overall performance of the pavement (Kuo and Freeman 1998, Maerz 2004). A number of researchers reported that form and surface texture of aggregates have significant effect on the mechanical property of th...

6 Summary The rendering process of discrete samples was described as a resampling process divided in two phases: reconstruction and traversal. Then, rendering acceleration techniques were classified into three different groups: using pre-computed information, controlling image quality, and simplifying viewing transformation. Finally, volume rendering algorithms were presented, divided into four...

Friction stir welding (FSW) is a promising technique to join aluminum alloys without having problems encountered during fusion welding processes. In the present work, the evolution of microstructure and texture in friction stir welded thin AA2024 aluminum alloy are examined by electron backscattered diffraction (EBSD) technique. The sheets with 0.8 mm thickness were successfully welded by frict...

Microstructure evolution, mechanical properties, formability, and texture development were determined for AA6111 samples processed by asymmetric rolling (ASR) with different roll friction, velocity, or diameters, conventional rolling (CR), and equal-channel-angular pressing (ECAP). Highly elongated or sheared grain structures were developed during ASR/CR and ECAP, respectively. ASR led to impro...

The potential use of carbon fibre laminate composites is limited by the weak out-ofplane properties, especially delamination resistance. The effect of incorporating titanium carbide to the mesophase pitch matrix precursor of carbon fibre laminate composites on interlaminar shear strength is studied both on carbonised and graphitised composites. The presence of titanium carbide modifies the opti...

in order to improve food texture, hydrocolloids are used widely as gelling material in food systems. wild sage seed has remarkable amounts of gum (mucilage) with good functional properties. this mucilage also improves the rheological, textural and functional properties of foods. in this study the effects of different drying methods including hot air drying (40, 50, 60, 70 and 80°c), freeze dryi...

objective roughness is the main parameter in interlocking bonding mechanism. yet there is no model designed to evaluate the effect of surface roughness on adhesion of coating materials in pharmaceutical sciences. materials and methods in this study polymethyl metacrylate spherical beads with different sizes were poured into 10 mm mold, then it was pressed by hand screw and finally heated to 141...

The elastoviscoplastic single crystal constitutive model incorporating non-Schmid effects developed by Dao and Asaro (Mater. Sci. Eng. A, 1993, vol. 170, pp. 143-60) is introduced into Asaro and Needleman's (Acta Metall., 1985, vol. 33, pp. 923-53) Taylor-like polycrystal model as well as Harren and Asaro's (J. Mech. Phys. Solids, 1989, vol. 37, pp. 191-232) finite element polycrystal model. Th...

Proximate composition (moisture, protein, total fat, and total ash) and textural characteristics (hardness, adhesiveness, springiness, cohesiveness, chewiness and firmness and work of shear) of cooked sausages formulated from mechanically deboned chicken meat (MDCM) with addition of chicken offal (heart, gizzard or liver) were investigated. Chicken offal replaced equal weight (15 kg) of MDCM in...
