Landscape can not only effectively improve the residents' living happiness, but also promote the improvement of the city's ecological environment. Among them, colored leaf plants are commonly used tree species in landscape design. Relevant designers are required to skillfully use them in order to enrich the landscape color and to better activate the landscape atmosphere. This paper analyzes the characteristics of color-leafed plants and discusses their application skills in landscape design in order to improve the quality and aesthetic feeling of urban landscape design.展开更多

The idea of humanization is based on people's actual needs, closely combining humanization with the development of modern society, so that people's needs can be effectively satisfied. After analyzing the current development situation, it is found that the humanized concept applied in landscape architecture design is relatively limited. Under the background of vigorous development of landscape architecture construction, it becomes more critical to embody the humanized concept in landscape architecture design, in order to further enrich the design connotation, strengthen people's aesthetic consciousness and effectively meet people's actual needs. Next, the article discusses the application of humanized design concept in landscape architecture design.展开更多

This framework integrates development costs as an equally important factor alongside weight and aerodynamic disciplines within the UAV design process. The OpenMDAO paradigm is employed to facilitate a standalone design and optimization application. A comprehensive multidisciplinary analysis module is developed, encompassing initial geometrical sizing, weight analysis, aerodynamic performance evaluation, and estimation models for development costs. The effectiveness of the framework is validated through a low-cost, high-performance UAV case study. The results demonstrate that neglecting the influence of UAV development costs would be imprudent. By appropriately adjusting design parameters using the optimization algorithm, significant reductions in UAV development costs can be achieved with minimal performance losses.展开更多

Fractal theory is adopted to create image automatically, which is applied to design knitted sweaters. Based on Mandelbrot set(M-set), image could be generated automatically by visual basic (VB) program. Plenty of wonderful patterns are created by the following methods: selecting any parts of the image and magnifying, extending generalized M-set, editing the selected images with photoshop. The edited pattern is used to set on any parts of clothes to show fashion effect. Actual knitted structure is simulated by knitting CAD software. The results show that the fractal theory has greater potential applications in knitted pattern design, and it deserves further research.展开更多

The absorber consists of three layers, and the difference is that the four split ring resonators made of metal gold are encrusted in the gallium arsenide （GaAs） plane in the top layer. The simulated results show that a perfect absorption in the region from 481.2 to 684.0THz can be obtained for either transverse electric or magnetic polarization wave due to the coupling effect between the material of GaAs and gold. The metamaterial is ultra-thin, having the total thickness of 56nm, which is less than one-tenth resonance wavelength, and the absorption coefficients at the three resonance wavelengths are above 90%. Moreover, the effective medium theory, electric field and surface current distributions are adopted to explain the physical mechanism of the absorption, and the permittivity sensing applications are also discussed. As a result, the proposed structure can be used in many areas, such as solar cell, sensors, and integrated photodetectors.展开更多

Analternative to Taguchi's, the robustness application design method has been recently presented.However, neither Taguchi's method nor the alternative method is capable of dealing satisfactorilywith the frequently encountered situations in which all the noise variables cannot be studiedsimultaneously. Based on the ideas from response surface modeling, linear models theory, and randomeffects models, we provide a method for estimation in the robustness application design method inproduct quality applications. With this new method used, the high-quality ratio of the productdesigned could be increased, and the ability to resist the influence of various disturbing factorsand noise factors could be enhanced.展开更多

A program is created using several multi media software to simulate the mechanism of moulding processes in order to let s tudents understand the concept of mould design. In addition, students can even access the program through the Internet. Therefore, the software is defined as Multimedia and Internet Technology (MIT) program. The MIT program consists of four sections: (i) simulation of mould mechanisms, ( ii) cooling system, (iii) material information and (iv) games for tutorials. Sec tion One covers the basic operations of different types of moulds such as two-p late mould, three-plate mould, split mould, side-core mould and mould with und ercuts. Section Two introduces different types of cooling systems such as bubble r, baffle, cooling circuits, etc. Section Three provides some useful material in formation for mould design. Section Four contains games of matching mould compon ents, mould design problem finding and multiple choice questions to test student s how much they understand mould design concept. Multimedia is highly effective particularly in teaching and learning. It changes the nature of learning itself. It makes reading dynamic by giving words an impo rtant new dimension. It allows students to see, hear and do simultaneously, thus significantly reducing average learning time. Furthermore, through cooperative learning on Internet, students can access the program, share data or search info rmation anytime anywhere.
