The paper proposes a design method for the layered and ring-shaped acoustic cloaking based on BM. According to the theory of PM cloaking, physical parameters of the ring-shaped acoustic cloaking are given by theoretical design. Further, based on the features of microstructure of BM, the relationship between the parameters of each layer of microstructure of BM and the analytic expression of the physical parameters of acoustic cloaking made of BM is determined, and the design methods for microstructure of layered and ring-shaped acoustic cloaking are discussed, namely, radial equidistant layered design and radial non-equidistant layered design (i.e. equal sectorial angle layered design). At last, according to the radial non-equidistant layered design parameters of the ring-shaped acoustic cloaking, the microstructure model of the layered and ring-shaped acoustic cloaking is designed. The results of the study can serve as theoretical basis for actual production and application of acoustic cloaking.

The Mathematical Model

In order to establish the design method of a noncircular face gear (NFG) with intersecting axes, the meshing theory of this gear is investigated based on the principle of space gear meshing. A generalized approach for designing closed pitch curve of the NFG with intersecting axes was proposed based on Fourier series. The mathematical model of the NFG generated by a shaper cutter was established. The fundamental design parameters of the gears were defined, with the principle for determining their values discussed. The prototype of a NFG was machined by 5-axis CNC milling and the motion rule was tested. Experimental results verify the feasibility of the innovative transmission mechanism and the correctness of the mathematical model of NFG with intersecting axes.

Tool Performance

As has been demonstrated in the “microfactory” which is a miniature manufacturing system proposed by the author’s research group, small machine tools that are comparable in size to their target products lead to large reductions in energy consumption and area. Experiments showed that they were capable of micro mechanical fabrication. However, the design of miniature machine tools has not been fully optimized. The author proposed a design method to estimate machine tool performance. In this paper, the design tool is applied to find miniaturizing strategies. By applying the design tool, it is possible to determine which of the design parameters and error sources would significantly affect machine performance. From the results of calculation, the tool can clarify the effect of machine tool sizes imposed on the machine performances. This leads to some suggestions regarding machine tool sizes. Finally, design guidelines for miniature machine can be obtained.

For a typical Full-hybrid electric vehicle (HEV) layout, such as Toyota Prius, the power-slit device (PSD) is a key component. Determination of volume or weight of a PSD is an important issue in preliminary design of power transmission applications. The purpose of this paper is to preliminary design of PSD gear drives by minimizing volume of gear trains. A stochastic approach Genetic Algorithm (GA) was applied to a differential-based coupling PSD design problem. Static and dynamic penalty functions were introduced to the objective function for handling the design constraints. The calculation of quadratic mean deviation and dynamic bounding parameter values such as determination of crossover and mutation parameter values were adopted to ensure the convergence of the fitness function. The optimized design method based on GA produced quite well results, which promptly supplied preliminary design parameters of gear drives for differential-based coupling PSD design.

With computer technology contentiously improving, parametric design has been playing much more important role in architectural design. Parametric Design, as a design method and a tool arisen with information age, is the most recent trend in architecture. Parametric design tool improvements and wide application options has undoubtedly motivated building structural design and brought up more complex architectural works, especially on nonlinear structures. Sports buildings, due to their special functions, it calls for structures that provide large span. Therefore, there are many technical requirements in the design of sports buildings. Traditionally, sports building form is limited by structural calculation. With improved computer technology, especially parametric design tools, sports building forms become more diversified, complex and nonlinear. Parametric design helps with the dynamic interaction between architects and heir work, consequently achieves quick design and dynamic adjustments of complex structures, simplifies the design process, and finally provides more efficient and direct design method for sports building design.

Concrete mix design is the science to obtain concrete proportions of cement, water, and aggregate, based on the particular concrete design method and their mix design parameters. However, the suitability of concrete proportion for high-performance concrete depends on resulting mix factors, namely, water, cement, fine aggregate, and coarse aggregate ratios. This paper implements the multicriteria decision-making techniques (MCDM) for ranking concrete mix factors and representative mix design methods. The study presents a framework to identify critical mix factors found from the concrete mix design methods for high-performance concrete using the two-phase AHP and TOPSIS approach. Three methods of concrete mix design, namely, American Concrete Institute (ACI) mix design method, Department of Energy (DOE) method, and Fineness Modulus (FM) method, are considered for ranking mix design methods and the resulting mix factors. Three hierarchy levels, having three criteria and seven subcriteria, and three alternatives are considered. The present research is attempted to provide MCDM framework to rank the concrete mix guidelines for any given environment such as concrete under sulphate and chloride attack and for evolving the performance-based concrete mix design techniques. Sensitivity and validation analysis is also provided to demonstrate the effectiveness of the proposed approach.
