Easy Operation

In order to meet requirement of separation screen for tenebrio molitor L, one separation screen was designed, this product has a good separation, simple structure, low cost, high efficiency, easy operation. Based on the analysis of design requirement of separating screen for tenebrio molitor L, overall structure, working principle and the main structural parameters were determined. The kinematic mathematical model of shaking mechanism was established by using the vector method. The kinematics analysis of shaking mechanism was conducted by using Matlab, the displacement, velocity and acceleration curves of sieve box were obtained. The performance test showed that the prototype machine can screen different instar tenebrio molitor L and frass, this machine has good screening effect. In addition, machine design and performance are able to meet the design requirements.

In this paper is carried out the selection and simulation of a one degrees of freedom (DOF) leg mechanism. The leg mechanism consist of a nine bar linkage and is based on a Low-cost Easy-operation idea. Virtual simulation tests of the model shows the feasible of the proposed leg mechanism, for human leg motion assistance. Kinematics and dynamics analysis of the leg mechanism is carried out. Finally, dynamic simulation results reveal the motion characteristics and performance of the leg mechanism.

Safety side in engineering has been thought of as variety one priority in development of latest vehicle. Each single system has been studied and developed so as to satisfy safety demand. Instead of having bags, sensible suspension systems, sensible handling and safe cornering, there’s one of most crucial system within the vehicle that is brake systems. Without brake within the vehicle can place a traveller in unsafe position. Therefore, it’s a requirement for all vehicles to own correct brake. Due to vital system within the vehicle, several of researchers have conducted a study on brake and its entire part. In this project, the author has conducted a study on aerated and traditional disk brake of traditional traveller vehicle with full load of capability. The brake must be sufficiently designed in order to dissipate the heat generated from the braking process adequately for safe braking system performance. The aim of our project is to design and investigate the braking performance of the low cost passenger car with various materials like stainless steel, cast iron and aluminium alloy. The disc brake structure is changed with cross-drilled holes on the rotor of the disc for more heat dissipation using CATIA V5 R21 and performance study in term of its Structural property was determined using ANSYS finite element analysis software

The Cost

In this paper, a low-cost water electrolyzer is developed and its performance study is presented. Locally found materials are used to develop the electrolyzer. The electrolyzer has two cells connected in parallel and bipolar electrode configuration. In common, different cells are connected in series but for this electrolyzer parallel connection has been tested. A very thin polymer, Nylon-140 has been used as separator membranes for this electrolyzer. In separator membrane assembly, the designed geometry creates two separate gas channels internally which enables the direct collection of hydrogen and oxygen gas from the designated outlet port of the electrolyzer. The geometry excludes the need of external tubing into each cell-compartments to collect hydrogen and oxygen separately. The developed electrolyzer is found to be 42% efficient with its highest production rate of 227.27 mL/min. The purity of hydrogen is found to be more than 92% and justified with the burn test. The cost is 20 times less than the commercial electrolyzers. The development method and scheme can be helpful to popularize the small scale use of hydrogen in Bangladesh for various renewable energy applications. Dhaka Univ. J.

And Performance

A recent series of experiments suggests that fostering superstitions can substantially improve performance on a variety of motor and cognitive tasks ( Damisch, Stoberock, & Mussweiler, 2010 ). We conducted two high-powered and precise replications of one of these experiments, examining if telling participants they had a lucky golf ball could improve their performance on a 10-shot golf task relative to controls. We found that the effect of superstition on performance is elusive: Participants told they had a lucky ball performed almost identically to controls. Our failure to replicate the target study was not due to lack of impact, lack of statistical power, differences in task difficulty, nor differences in participant belief in luck. A meta-analysis indicates significant heterogeneity in the effect of superstition on performance. This could be due to an unknown moderator, but no effect was observed among the studies with the strongest research designs (e.g., high power, a priori sampling plan).
