Lap joints of commercially pure magnesium plates to aluminium plates (Magnesium plate on the top, and Aluminium plate, grade 1100, on the bottom side) were conducted by friction stir welding using various traveling and rotation speeds of the tool to investigate the effects of the welding parameters on the joint characteristics and strength. Defect-free lap joints were obtained in the welding tr...
Heat transfer in the mold is the heart of the continuous casting process and its quantitative analysis was pioneered by Keith Brimacombe. With many different processes currently competing, it is appropriate to apply modeling to investigate the theoretical limits of continuous casting speed and productivity. The heat transfer rate during solidification processes drops with time so the shell thic...
Background. This study aimed to analyze core muscle fatigue effects on the kinematic parameters change during volleyball jump serve. Methods. The participants were sixteen experienced male volleyball players with average age, height, and body weight of 24.6 ± 1.8 years, 1.85 ± 1.6 m, and 79.5 ± 3.5 kg, respectively. This study utilized two high-resolution video cameras, a drone video, a lactat...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
Friction stir welding (FSW) is an economic and high quality technique at aluminum welding and joining methods. The most important factor in the soundness of this type of welding, is the mechanism of material transfer in each tool rotation. The materials transfer during the welding process involves horizontal and vertical movement that caused by extrusion process and forging force (the tilt angl...
Objective: The purpose of this study is to find the optimum training conditions for selective strengthening of the vastus medialis oblique muscle over vastus lateralis. Methods: For this purpose, a musculoskeletal model of lower limb was developed by OpenSim software. Using a detailed tibiofemoral and patellofemoral joint modeling and six muscular branches for components of quadriceps femori...

In the conventional continuous casting of steel, either mold powder or oil can be added to lubricate the mold from sticking to the solidifying steel shell. The mold powder melts to form a molten slag or flux layer, and also acts to protect the molten steel from oxidation, to insulate the molten steel from heat loss, to absorb inclusions from the molten steel, to regulate heat transfer to mold w...
today, information technology and computers are indispensable tools of any profession and translation technologies have become an indispensable part of translator’s workstation. with the increasing demands for high productivity and speed as well as consistency and with the rise of new demands for translation and localization, it is necessary for translators to be familiar with market demands an...
Benchmarking of spatio-temporal databases is an issue of growing importance. In case large real data sets are not available, benchmarking requires the generation of artificial data sets following the realworld behavior of spatial objects that change their locations, shapes and sizes over time. In this report, a generator for changing raster data, called “Generator of Time-Evolving Regional Data...
