The main shortages of traditional design for silk garment are: stylized design concept; simple and plane model; lack of diversified skin texture; and the color limit to the inherent quality of silk fabric, not fit for diversified and personalized aesthetic need of modern people. This paper breaks through traditional fabric design, and proposes optimization design methods of modern silk garment. The methods include matching different silk fabrics with different textures, or matching silk fabrics with other fabrics such as leather, fur, jean and knits.

Shaking Moment

Dynamic balance of the spatial engine is researched. By considering the special wobble-plate engine as the model of spatial RRSSC linkages, design variables on the engine structure are confirmed based on the configuration characters and kinetic analysis of wobble-plate engine. In order to control the vibration of the engine frame and to decrease noise caused by the spatial engine, objective function is choosed as the dimensionless combinations of the various shaking forces and moments, the restriction condition of which presents limiting the percent of shaking moment. Then the optimization design is investigated by the mathematical model for dynamic balance. By use of the optimization design method to a type of wobble-plate engine, the optimization process as an example is demonstrated, it shows that the optimized design method benefits to control vibration and noise on the engines and improve the performance practically and theoretically.

Two lichens species (ParmotremapraesorediosumandHeterodermialeucomelos)were assessed for dye production using boiling water method (BWM) and ammonia fermentation method (AFM). The dyes were applied on silk fabric. Three types of mordant were used i.e. alum, iron and vinegar through meta-chrome (simultaneous) method of natural dyeing. The K/S values, colour coordinates values and colour differences (ΔE) of the dyed samples were measured. Dyeing fastness properties of the dyed silk fabrics were assessed for washing, rubbing and light. TheP.praesorediosumextracts yielded beige to dull brown shades using BWM and pinkish-purple using AFM, whereas theH.leucomelosextracts produced yellowish-brown shades for both BWM and AFM on the silk substrate. Modanting seemed to be effective in increasing the K/S values of all mordanted fabrics except in the case of silk fabric dyed withP.praesorediosumextracted from AFM. Fastness ratings to washing and rubbing were all very good (5-4) for bothP.praesorediosumandH.leucomelosdyed silk fabrics. The fabrics dyed withP.praesorediosumandH.leucomelosextracts produced strong and deep colours as their ΔE values were higher and increased obviously of all mordanted fabrics. It can be concluded thatP.praesorediosumandH.leucomelosextracted from BWM and AFM methods can be used as an alternative dye source.

This article explores the ecology of late-modern askesis through the concept of ‘ethical infrastructure’: the array of goods, locales, technologies, procedures, and sundry pieces of equipment upon which the possibility of ethicists’ striving is premised. By looking at the ethnographic case of halal living among Muslim pietists in post-Soviet Tatarstan (Russia), I advance a framework that highlights the ‘profane’, often unassuming or religiously unmarked, yet essential material scaffolding constituting the ‘material conditions of possibility’ for pious life in the lifeworld of late modernity. Halalness is conceptualised not as an inherent quality of a clearly defined set of things, but as a (sometimes complicated) relationship between humans, ethical intentionality, and infrastructurally organised habitats. Pointing beyond the case of halal, this article syncretises theories of self-cultivation, material religion, ethical consumption, and infrastructure to address current lacunas and explore fresh theoretical and methodological ground. This ‘ethical infrastructure’ framework enables us to conceptualise the embeddedness of contemporary ethicists in complex environments and the process by which processes of inner self-fashioning change and are changed by material worlds.

R&D outsourcing becomes the often-adopted strategy for firms to innovate. However, R&D cooperation often ends up with failure because of its inherent quality of instability. One of the main reasons for cooperation failure is the opportunistic behavior. As the R&D contract between firms is inherently incomplete, opportunistic behavior always cannot be avoided in the collaborative process. R&D cooperation has been divided into horizontal and vertical types. This paper utilizes game theory to study opportunistic behavior in the vertical R&D cooperation and analyzes the equilibrium of the cooperation. Based on the equilibrium and numerical results, it is found that the vertical R&D cooperation is inherently unstable, and the downstream firm is more likely to break the agreement. The level of knowledge spillovers and the cost of R&D efforts have different effects on firms’ payoffs. When the level of knowledge spillover is low or the cost of R&D efforts is high, mechanisms such as punishment for opportunism may be more effective to guarantee the stability of cooperation.

This paper presents a methodology to find the optimum build orientation in the additive manufacturing of topologically optimized structural parts. The outlined methodology is based on applying a differential operator to the density distribution matrix of a topologically optimized design. The methodology is developed for 2D parts, where the profile of the geometry is constant. The 2D spatial difference operator effectively calculates the elemental density gradient vector, ultimately used to calculate the angles between i) overhanging surfaces of a topology optimized design, and ii) the build platform of a 3D printer. These angles, referred to as build angles, are used to estimate the relative amount of supporting structure required to print the design at a prescribed part orientation. This methodology can potentially be adopted to simulate the additive manufacturing surface quality of density based, structural topology optimization designs.

Equal margin design method based on the classic analytic formula is widely used in development of extra-high voltage bushing products, and its effectiveness and practicality have been fully validated. However, model and temperature factors have significant impact on internal E-field distribution of UHVAC and UHVDC bushing condenser, which traditional analytic formula is difficult to evaluate quantitatively, so it’s necessary to improve traditional equal margin design method. Firstly, basic principles of equal margin design method and its software package were briefly described, and the laws of model and temperature factors influencing on condenser E-field were investigated on FEM (finite element method) computing platform. Based on these, mathematical model of improved equal margin design method for bushing condenser was established, and flow chart of optimization process combining FEM electro-thermal coupling calculation with genetic algorithm was presented. The improved method was applied to design of UHV RIP oil-gas prototype to realize uniform axial E-field distribution along bushing condenser and equal partial discharge margin between adjacent foils. Bushing condenser was fabricated according to above optimized design structure, and has passed all type tests. In the paper, the FEM electro-thermal coupling calculation method was applied to the inner insulation optimization design to make bushing condenser’s design more suitable. The paper can provide some theoretical guidelines for research and development of other bushings in UHV level.

Low speech privacy in shared and private offices in one of the early generation of a “green” building resulted in occupants' dissatisfaction. This problem is experienced in Liu institute with a natural-ventilation system. Such a system requires low air-flow resistance which is achieved by large openings which will result in noise transmission between various spaces within the building. The poor acoustical quality in this building resulted in occupants' noise complaints which were further investigated by way of relevant acoustical measurements. CATT-Acoustic software was utilized to modify the acoustical quality of the building without any disturbance to the occupants. The optimized design of the transfer box above the office door was selected based on CATT-Acoustic predictions. The acoustical measurements were conducted after installation of the transfer box above the office door. The measurements' results agreed with the predictions which led to improved speech privacy to an acceptable level between the office and the corridor in Liu Institute. More work should be done to improve the acoustical quality of natural-ventilated building to conform to ANSI standards.1The results of this study strongly support including acoustics in “green” building designs with natural ventilation to avoid users' complaints.
