Dynamic mixers are widely used in hydrometallurgical processes. Improvement in mixers' efficiency is one of the greatest challenges in this research.The geometrical factors of the impeller are of the most important elements ...

Assistive device equipment can improve the performance of sit-to-stand (STS), standing, and walking of people with lower limb disability. The motorized assistive device is usually expensive and the use of another assistive ...

The main purpose of the study is to evaluate the effectiveness of these dead-points mono laterally in controlling the space location of the structures against the explosion loading in this regard. For ...

The aim of this research is to determine the proper concentration of Titanium Tetra IsoPropoxide (TTIP) and select the right temperature and time of calcinations for the synthesis of B4C-nano TiB2 ...

In this paper, the static pull-in instability (SPIV) of beam-type micro-electromechanical systems is theoretically investigated. Herein, modified strain gradient theory in conjunction with Euler–Bernoulli beam theory have ...

Parallel kinematic machines, are closed loop structures which have more accuracy, stiffness and ability to withstand high loads. Kinematic of these mechanisms is complicated due to their closed–loop structure, parallel ...

Surfacequality along with the low production cost, play significant role in today's manufacturing market. Quality of a product can be described by various parameters. One of the most important parameters affecting the ...
