To improve the objectivity and accuracy of evaluation for electromagnetic environment complexity and its influence on communication equipment, a subjective complexity evaluation method of electromagnetic environment oriented to the communication equipment is presented based on sensitivity and RF protection ratio of communication equipment. Based on statistical concept, the energy correlation factor is modified, and modulation and polarization correlation concept are imported into this method, by which the factor of energy correlation is modified and the subjective evaluation is made by analyzing the time domain correlation, frequency domain correlation, energy domain correlation, modulation correlation and polarization correlation of the electromagnetic environment. These simulation results indicate that communication equipment with various working parameters are influenced differently under the same electromagnetic environment. Namely, the complexities of electromagnetic environment for communication equipment with various working parameters are different.

The aim of this study was to develop a teaching model of multilateral basic movements based on characteristics of students. This produce focused on three basic movement: locomotors, non locomotors, manipulative. To to produce the prototype of the materials, ADDIE model was applied. The development of the teaching model was conducted in five steps: (1) Analyze, (2) Design, (3) Develop, (4) Implement, and (5) Evaluate. The models was revised by using self evaluation and experts review evaluation. In order to see the practicality of the product, the models was tried out by using small group and Field Test Evaluation Method in the 2nd grade of SD Negeri 52 Parupuk Tabing Padang. Meanwhile to see the effectiveness of the learning materials developed, the models was tried out by using field test evaluation method at SD Negeri Percobaan Padang. Based on the results of the research, it is concluded that multilateral movement skill teaching models based games for the 2nd grade students of elementary school are valid, practical, and effective.

Driver’S Intention

In order to improve the transmission efficiency and carrying capacity of conventional single-belt continuously variable transmission (CVT), one new type of dual-belt CVT is proposed in this paper. Under the situation that this new dual-belt CVT should be switched between single- and dual-belt modes frequently according to driver’s intention and road conditions, so five objective evaluation indexes of mode switching quality for the dual-belt CVT are proposed, considering the aspects of vehicle power, comfort, and transmission durability comprehensively. Then, the objective evaluation model of mode switching quality is established by the BP neural network optimized by the genetic algorithm. It is found that the prediction results are consistent with the subjective evaluation. After analyzing the influence of the selected five evaluation indexes on the prediction results, it is obvious that these five evaluation indexes of mode switching quality for dual-belt CVT are reasonable.

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.

The Relationship

PurposeThis study aimed to clarify the criteria for subjective evaluation of the similarities and differences between virtual and actual pants and propose a quantitative evaluation method for those similarities and differences based on geometric features related to the evaluation.Design/methodology/approachUsing patterns, we made five pairs of actual pants for a dummy in five fabrics. We simulated virtual pants with a 3-D simulator. Sensory evaluation was conducted with images of the virtual and actual pants: 20 participants compared the images based on a questionnaire. For the structure of evaluation, the authors undertook analysis of variance and principal component analysis. The actual and virtual pants were geometrically compared using the 3-D scanned data. To investigate the relationship between quantitative and sensory evaluation, the authors calculated the correlation coefficients.FindingsThe authors found that subjects perceived the differences between actual and simulated pants. When comparing the virtual and actual pants, the criteria for the differences were the silhouette from the front view, hem width, waist and wrinkles. Using differences in the hem width, it would be possible to evaluate the differences between actual and simulated pants. Roughness and smoothness of the silhouette also affected evaluation.Originality/valueThe authors clarified the evaluation criteria for the similarities and differences between virtual and actual pants. The authors proposed a quantitative evaluation method for the similarities and differences between virtual and actual garment based on our criteria. This study will be of benefit to 3-D simulator users and developers.

Start Up

Creep control is a kind of start-up control for electric vehicle. In the paper, two closed-loop control is contained in the creep control strategy. Proportional control with torque limitation, which adjusts vehicle speed, is the outer-loop control; and anti-slip control is the inner-loop control. In this way, the vehicle speed indicates no overshoot and has uniform convergence with driving torque. Moreover, the vehicle can start up on low adhesion or split road, and the driver can control the creep speed by the brake pedal only, so that the driver’s operation is reduced. Subjective evaluation method is proposed to determine the control performance metrics, and then the mathematical relationship between the performance metrics and the control parameters is established. The tuning method of the control parameters is proposed according to those performance metrics, which mitigates the workloads of calibration and provides a better driving experience. Some simulations and real vehicle experiments are conducted to verify that the control strategy has an expected performance.
