Abstract To meet the requirements of large tolerance, high precision, soft capture and reliability space gripper, a three finger end effector is developed. The gripper adopts fingered configuration, which needs to be used together with corresponding adapter. It characterized by stable grip, clamping force, tolerance strong correction ability. A 6-DOF microgravity equivalent device innovatively ...

for all industrial processes, modelling, optimisation and control are the keys to enhance productivity and ensure product quality. in the current study, the optimization of process parameters for improving the conversion of isoeugenol to vanillin by psychrobacter sp. csw4 was investigated by means of taguchi approach and box-behnken statistical design under resting cell conditions. taguchi desi...

Technology-based interventions to promote health are expanding rapidly. Assessing the preliminary efficacy of these interventions can be achieved by employing single-case experiments (sometimes referred to as n-of-1 studies). Although single-case experiments are often misunderstood, they offer excellent solutions to address the challenges associated with testing new technology-based interventio...

the main objective of the present study is to investigate the feasibility of using carboxymethyl chitosan magnetic nanoparticles (ccmn) for the adsorption of cd2+. the study also reports important parameters, which affect the adsorption process, i.e., ph, adsorbent dose, contact time and concentration of cd2+, using box-behnken designs. firstly, functional carboxymethyl chitosan magnetic nanopa...

perlite or pearl stone is a natural glass which has formed by rapid cooling of viscous lava or magma. perlite is mainly composed of silica, aluminum, potassium and sodium. in this experiment, perlite was used as a low-cost source of si and al to synthesis of sodalite zeolite using the alkaline hydrothermal treatment. a statistical taguchi design of experiments was employed to evaluate the effec...

background a potential treatment for healing hepatic tissue is delivering isolated hepatic cells to the site of injury to promote hepatic cells formation. in this technology, providing an appropriate injectable system for delivery of hepatic cells is an important issue. in this regard, fibrin scaffolds were designed with many advantages over other scaffolds like cell delivery vehicles for biode...

Aiming at the common problems of high working resistance, low soil disturbance, and rates missed extraction in operation carrot combine harvesters, a high-efficiency drag-reducing bionic soil-loosening shovel was designed this study. The physical parameters carrots were measured, using badger claw toe as prototype. wing structures designed. Based on EDEM discrete element simulation technology, ...
