The wheat precision seeding technology provided an advanced agricultural protection for the high yield of wheat. But the lack of an effective agricultural machine made this technology difficult to apply widely. In this paper a quadruped wheel robot to achieve the wheat precision seeding technology was designed. And experimental study was taken under different operating conditions. Because of multiple effort factors, a quadratic orthogonal rotation combination design method was applied in the experiments, and identifying the main factors by analysis. Then the field test was carried out according to the main factors. The experiment results showed that the qualified rates of seeding exceed 93% in different sowing speed. That reached the agronomic requirements of wheat precision seeding.

The aim of this experimental study was todetermine the effect of all teaching methods, part, mixed and motivation result learning toward of flat service skill courts tennis. Learning motivation is divided into two parts, namely high andlow.This research was conducted at Faculty of Sport ScienceState University of Macassar,the academic year 2014/2015. Experimental using factorial design method 2x3. The sample consisted of 60 students were divided into 6 groups, each consisting of 10 students. Data analysis technique is a two-way analysis of variance (ANOVA) followed by Tukey's test at a significance level of α= 0.05. The results of this study indicate that ( (1) overall teaching methods higher effect of the part teacing methods on learning outcomes flat tennis service skills (2) overall teaching methods lower effect of the part teacing methods on learning outcomes flat tennis service skills, (3) overall teaching methods lower effect of the part teacing methods on learning outcomes flat tennis service skills,(4) there is interaction between the overall teaching methods, part teaching methods and combined teaching methods and learning motivation outcomes flat tennis service skills,(5) overall teaching methods higher effect of the part teacing methods on learning outcomes flat tennis service skillsusing a high learning motivation, (6) overall teaching methods lower effect of the part teacing methods on learning outcomes flat tennis service skillsusing a high learning motivation, (7) part teaching methods lower effect of the combined teacing methods on learning outcomes flat tennis service skillsusing a high learning motivation, (8) overall teaching methods higher effect of the part teacing methods on learning outcomes flat tennis service skillsusing a low learning motivation, (9) overall teaching methods lower effect of the part teacing methods on learning outcomes flat tennis service skillsusing a low learning motivation, (10) part teaching methods lower effect of the combined teacing methods on learning outcomes flat tennis service skillsusing a low learning motivation.

This contribution demonstrates the application of the new Design Method Validation System ( DMVS) for the validation of engineering design methods in product development. The application example is a case from the medical branch. The product design method Design for Mass Adaptation ( DfMAd) with individualization and modification steps as triggers is compared to an adapted design method with product individualization but without modification triggers. This experimental study was conducted in accordance with the DMVS procedure. Measured outcomes refer to the usefulness, applicability and acceptance of the design method DfMAd. Two groups of student participants were compared to each other through research tools based on quantitative and qualitative data collection and analysis. Findings show that the considered DfMAd phase successfully leads to the desired benefit for the consideration of variant-oriented alternatives, thus confirming the test hypothesis. In the example of a product, a crutch, a high treatment quality can be achieved by specific adaptability of the product. In addition, it is shown that DMVS is suitable for the development of experiments and that the data collection means are differently suited for the validation of the three criteria.

A parameter optimization design method is proposed for multiple coal bucket dampers (CBDs) to reduce the seismic response of coal-fired power plants. To test the damping effect of the optimized CBDs, a 1 : 30 scale shaking table test model of a power plant structure was fabricated. A comparative testing program was conducted using three seismic excitations on a model with and without CBDs. A finite element analysis model, replicating the conditions of the shaking table test, was constructed for comparison, and the shock absorption effects of CBDs subjected to 22 groups of far-field seismic action and 28 groups of near-field seismic action were analyzed. Finally, the influence of changes in the structural period on the seismic response of the CBD-equipped structure was studied. The results indicate that the use of CBDs in a coal-fired power plant structure, based on an optimization design method for multiple-tuned mass dampers (MTMDs), results in a significant reduction in the structure displacement response, displays a certain discreteness under different excitations, and maintains a certain damping stability even as the structural period changes. Overall, the use of CBDs is a promising prospect for improving the seismic performance of coal-fired power plant structures.
