Psychomotor Domain

To carry out evaluation comprehensively, we need appropriate instrument that suitable with domain that being evaluated. Evaluation instrument development with test has been conducted by experts. These instruments were only suitable to measure cognitive domain and part of psychomotor domain. To measure affective domain, we need to develop non-test evaluation instrument (alternative test). The development of this instrument tends to more difficult and complicated compare with instrument test evaluation instrument. Therefore, it does necessitate a through study to derive and elaborate affective domain to specific aspect to develop valid and reliable instrument.

Axial Piston

In order to realize that an asymmetric flow piston pump can control an asymmetric differential cylinder, a proposal about the application of an asymmetric flow-distributing axial piston pump is put forward. The new type of piston pump can output the flows with two different values to control the movement of the differential cylinder directly in the closed circuit and realize much ideal result of the control of the differential cylinder by a single pump. Also a simulation model of the hydraulic pump is established under the circumstance of SimulationX software, considering the characteristics of the movement of an individual piston, the oil compressibility, and the flow distribution area changed with the rotation angle. The key data of the pump is defined by means of digital simulation. In particular, an analysis is made on the dimension of the unloading groove of the port plate and the characteristics of the flow pulse of the pump. Furthermore, an experimental model pump is manufactured, the basic performances of the pump is tested on the experimental platform at various rotatory speeds such as pressure, flow and noise, in the end the accuracy of the principle is verified.

Acoustic Comfort

It is important to know the sound insulation of partitions in order to be able to compare different constructions, calculate acoustic comfort in apartments or noise levels from outdoor sources such as road traffic, and find engineer optimum solutions to noise problems. The use of lightweight partitions as party walls between dwellings has become common because sound insulation requirements can be achieved with low overall surface weights. However, they need greater skill to design and construct, because the overall design is much more complex. It is also more difficult to predict and measure of sound transmission loss of lightweight partitions. There are various methods for predicting and measuring sound insulation of partitions and some of them will be described in this paper. Also, this paper presents a comparison of experimental results of the sound insulation of lightweight partitions with results obtained using different theoretical models for single homogenous panels and double panels with and without acoustic absorption in the cavity between the panels.

This research based on the problems about learning evaluation in which was less attractive because it had not used evaluation instruments based on technology, especially the learning process during the Covid 19 outbreak. The purpose of this study was to develop an evaluation of Arabic learning for SMK in the form of an objective test based on Kahoot application during the Covid-19 outbreak. This research data were obtained from the interviews and students' responses to the evaluation. The interviews were conducted with groups of students as participants in the study, meanwhile, students' responses were confirmed to 32 students. The findings of this study indicated that the Arabic language objective test evaluation instrument by using the kahoot application was very feasible.  94% according to design experts, 96% according to material experts, 96% according to media experts. The results of the product effectiveness trial of the objective test evaluation instrument based on the kahoot application were 86% for one to one learner, 90% for the small group test, 88% for the field trial test. The development of an Arabic evaluation in the form of an objective test based on the Kahoot application during the Covid-19 outbreak had a significant effect on the evaluation of Arabic and could make students more active, independent and feel comfortable in the evaluation process. In line with that, this paper suggested the need for teacher and institutional involvement in solving the problem of community limitations in online learning evaluation.

This paper illuminates a new type of precision cropping process method with rotary striking action. The new process makes use of a controllable circumferential strike on a metal bar with a V-shaped notch. The working principle of the machine is described. Different types of metal bars have been tested, and both bad results and successful results were stated in the paper. The most ideal control mode has been obtained. The experimental results show that the new cropping process can crop bars with different materials and diameters. In some cases, it can be directly used in the subsequent industrial production.

In order to reduce the ignition energy of the tantalum nitride film transducer, a new type of energy exchangers bridge area was designed in this paper, and it was fabricated by MEMS technology. The parameters of ignition voltage, ignition energy, as well as action time were tested. The experimental results showed that in terms of ignition voltage, ignition energy, and action time, the value of the energy exchangers element of the new bridge area was lower than the value of the energy exchangers element of the conventional bridge area. In addition, ignition performance can be reduced by many energy exchangers in the new bridge area.
