Generation ＆ use of human 3D-CAD models

ICEM 2001 The 3～(rd) International Conference on Experimental Mechanics

作者： juergen Grotepass Engineering Solutions tecmath AG Sauerwiesen 2 Germany 67661 Kaiserslautern

＜正＞ Individualized products are one of the ten mega trends of the 21st Century with human modeling as the key issues for tomorrow’s design and product development. The use of human modeling software for computer based ergonomic simulations within the production process increases quality while reducing costs by 30%-50% and shortening production ***, the entire production chain can be designed, individualized models generated and analyzed in 3D computer environments, yielding a reduced time for production start and a reduction of fault specific costs. This presentation focuses on the use of human 3D-CAD models for both, the ergonomic design of working environments （i.e. cockpits, vehicles） and made to measure garment *** design for ergonomics is matched to human needs, thus prevealing health. Ergonomic simulation includes topics as human vision, reachability, kinematics, force and comfort analysis. Individualized 3D-models are generated that base on the physiognomy of real persons thus having the same measures and *** Germany more than 17 billions of Mark are moved to other industries, because clothes do not fit. The presentation displays the technology involved in the context from 3D-Scanning, automatic generation of body measures and the production of garments. Individual clothing tailored to the customer’s preference means surplus value, pleasure and perfect fit.3D scanning is the gateway to the worlds of virtual reality, model generation, simulation and animation. Scanning is done with a laser based data acquisition by triangulation. It takes 20 sec. to acquire the complete surface of a human being with a resolution of 1 to 2mm. The 3D model consists of up to 2 mio data points, where color adds a further attribute for many *** short scanning time of less than 20 sec. per person opens new dimensions for mass screening of large groups. This facilitates the large scale creation and maintenance of reliable population

Trends in Switching Markets

1998 International Conference on Communication Technology

作者： juergen Weber Siemens AG Public Communication Networks OEN SN BM 2K Business Management Asia Hofmannstr.51 D-81359 Muenchen Germany

＜正＞Telecommunication network operators face enormous challenges. Telephone- and ISDN networks,the global Internet and broadband networks are *** structures are changing rapidly,traffic volume per subscriber is increasing and the demand for bandwidth towards the subscriber is growing. Changes in network architecture,the so-called consolidation and the resulting increase in the size of exchanges are cost-saving measures for network *** consolidation first means decreasing the number of switches and network ***,switching intelligence must be centralized in a smaller number of switches while implementing larger remote switching units（RSU）. Furtheron,the convergence of the PSTN and the Internet as well as broadband communication will have tremendous impact on future capabilities, performance and services of PSTN switches.

＜正＞RF SiP technology is an enabling packaging platform for wireless communication, which is constrained by the fact that, today, SiP design is an "expert engineering" process-one that is not scalable as a general design solution. To facilitate a move to mainstream SiP implementation, an integrated, scalable SiP design solution

In our study we investigated the relevance of functional phenotypes and genotypes by analyzing physiological parameters of APs and mRNA expression of chamber specific genes and the eletrophysiological characteristics of different cardiomyocytes in developing fetal heart. Combining single cell RT-PCR and patch clamp we found that almost one third of the measured cells (34.8%) were featured with pacemaker-like APs in the posterior section,which expressed a-MHC exclusively,while those with atrial:like APs exhibited transcripts of both a-MHC and ANE In the middle section,all three transcripts were identified in 92% of the cells exhibiting ventricular-like APs (APD=150.7±1.1ms) while the rest showed only the expression of a-MHC and ***,a significantly prolonged APDgo (233.9±2.0ms) was recorded in the OFT as compared to the middle part,which might well explain its function as an electrophysiological sphincter,a-MHC and MLC2v transcripts were detected in this *** on the findings mentioned above,we conclude that during early cardiac development,the exclusive expression of a-MHC is an indicator for pacemaker-like ***2v can be used as a specific marker for ventricular-like cardiomyocytes and atrial cells can be identified by co-expression of a MHC and ANF.

离子迁移率的非线性函数反映了物质本身的微观碰撞特性,是FAIMS技术实现离子分离检测的基础。现有的离子迁移率非线性函数求解方法多是近似求解,存在较大误差。该工作提出了一种基于半正弦分离电压和FAIMS谱图峰位置下的严格求解方法,推导出严格的二阶、四阶系数求解方程。利用自制的高场不对称波形离子迁移谱仪分别对乙醇、间二甲苯和正丁醇三种典型的醇和苯类物质进行检测,获取了三种物质的FAIMS谱图,通过谱图峰位置获得了不同分离电压值下的补偿电压,利用最小二乘法求出三种离子非线性函数二阶、四阶系数。拟合后的均方误差表明FAIMS非线性函数严格求解的方法,明显优于现有的求解方法。有助于提高FAIMS检测分辨率,进而有助于建立更加准确的FAIMS图谱,实现FAIMS对检测物质的精准识别。

In this article, we give the construction of new four-dimensional signal constellations in the Euclidean space, which represent a certain combination of binary frequency-shift keying (BFSK) and M-ary amplitude-phase-shift keying (MAPSK). Description of such signals and the formulas for calculating the minimum squared Euclidean distance are presented. We have developed an analytic building method for even and odd values of M. Hence, no computer search and no heuristic methods are required. The new optimized BFSK-MAPSK (M = 5,6,···,16) signal constructions are built for the values of modulation indexes h =0.1,0.15,···,0.5 and their parameters are given. The results of computer simulations are also provided. Based on the obtained results we can conclude, that BFSK-MAPSK systems outperform similar four-dimensional systems both in terms of minimum squared Euclidean distance and simulated symbol error rate.

Plant-pollinator in teractio ns have a fundame ntal in fluence on flower evolution. Flower color signals are frequently tuned to the visual capabilities of important pollinators such as either bees or birds, but far less is known about whether flower shape in fluences the choices of pollinators. We tested European honeybee Apis mellifera pref ere nces using novel achromatic (gray-scale) images of 12 insect-pollinated and 12 bird-pollinated native Australian flowers in Germany;thus, avoiding in flue nces of color, odor, or prior experie nee. In depende nt bees were tested with a number of parameterized images specifically desig ned to assess pref ere nces for size, shape, brightness, or the number of flower-like shapes prese nt in an image. We show that honeybees have a pref ere nee for visiti ng images of in sect-polli nated flowers and such a pref ere nee is most-likely mediated by holistic in formati on rather than by in dividual image parameters. Our results in dicate an giosperms have evolved flower shapes which in fluence the choice behavior of importa nt pollinators, and thus suggest spatial achromatic flower properties are an important part of visual signaling for plantpollinator in teractions.

It is not objective to rate the decision-making factors in the traditional failure mode and effect analysis,so fuzzy semantic theory is used in this *** fuzzy semantic scales and their corresponding semantics are summarized,and a defuzzification method is studied to obtain the fuzzy value table of the six fuzzy semantic *** the conflicts between experts in the traditional failure mode and effects analysis,a conflict-resolution algorithm is studied to obtain the failure risk ***,a certain type of industrial valve is used as an example to prove the validity of the theory proposed in this paper.
