Network Centrality (NC) is for the analysis of static network to find out to which degree an element is central to a network. This paper presents three NC functions that are newly added to the simulator General-purpose Petri Net Simulator (GPenSIM). With these new functions, in addition to the usual performance analysis of a discrete-event system via a Petri net model, supplementary information about NC of the elements can also be found, paving an overall (static + dynamic) analysis of the system.

In this work, thermoforming was adopted to manufacture woven carbon fiber/thermoplastic polyurethane (TPU) composite structures. Before that, differential scanning calorimeter was used to characterize the glass transition temperature and the melting point of the thermoplastic composite. Then, the simple structures with the omega shape were manufactured to investigate the effect of the lamination sequence and the blank holding pressure. Finally, the structure of a small luggage box was manufactured to examine its quality. The results indicate that the glass transition temperature of the thermoplastic composite is around $82.66 ^{circ}mathrm{C}$ and its melting temperature is about $190.60 ^{circ}mathrm{C}$. Therefore, the forming temperature of the composite is set to $170 ^{circ}mathrm{C}$, and the temperatures of the top mold and the low mold are $100 ^{circ}mathrm{C}$ and $160 ^{circ}mathrm{C}$, respectively. From the results of the simple structure, the lamination sequence of $[ ( 0 ^{circ}/ 90 ^{circ})]$ and $[ ( + 45 ^{circ} /- 45 ^{circ})]$ have quilt different material flowing during the process such that they have different product contours. The blank holding pressure could improve the product quality as compared to zero pressure. By using these forming parameters, one could manufacture a good product of the small luggage box.
采用热成形技术制备了机织碳纤维/热塑性聚氨酯(TPU)复合材料。在此之前,采用差示扫描量热计对热塑性复合材料的玻璃化转变温度和熔点进行了表征。然后,制作了omega形状的简单结构,研究了层压顺序和压边压力的影响。最后,制作了一个小型行李箱的结构,并对其质量进行了检验。结果表明:热塑性复合材料的玻璃化转变温度约为$82.66 ^{circ}mathrm{C}$,熔融温度约为$190.60 ^{circ}mathrm{C}$。因此,将复合材料的成形温度设置为$170 ^{circ}mathrm{C}$,上模和下模的温度分别为$100 ^{circ}mathrm{C}$和$160 ^{circ}mathrm{C}$。从简单结构的结果来看,$[(0 ^{circ}/ 90 ^{circ})]$和$[(+ 45 ^{circ}/ - 45 ^{circ})]$的层压顺序在加工过程中被不同的材料流动,从而具有不同的产品轮廓。与零压相比,压边压力可以提高产品质量。利用这些成型参数,可以生产出较好的小箱包制品。

The composite materials with the specified mechanical property open new opportunities for the material optimization. Notably, in 3D printing, several materials can be applied in a single manufacturing process. The critical review of various materials shows a new path to use these materialsboth in Selective Laser Sintering (SLS) printing and in the filament for Fused Deposition Modeling (FDM) printing. The idea of optimization is crucial by relying on the mechanical property of materials and automate it in 3D printing. It is performed by considering the input parameters and the application of the products. The current problem of multi-material optimization is the lack of thorough material property analysis and implementation to develop a proper database. Thus, Finite Element Analysis (FEA) on the selected materials with different specimens and with reasoning results is discussed to investigate materials property. The obtained results can be applied to the material optimization process by selecting proper material according to the boundary conditions. The algorithms of topology optimization indicate the proper application of the obtained results. In this paper, 3D printing through the physical algorithm with the methods of active and inactive points of investigation on geometry is presented. Thus, the inactive points can be excluded, and the material usage could be reduced.
具有特定力学性能的复合材料为材料优化开辟了新的机遇。值得注意的是,在3D打印中,可以在单个制造过程中应用几种材料。通过对各种材料的综述,揭示了这些材料在选择性激光烧结(SLS)打印和熔融沉积成型(FDM)打印中应用的新途径。优化的想法是至关重要的,因为它依赖于材料的机械性能,并在3D打印中实现自动化。它是通过考虑输入参数和产品的应用来实现的。目前多材料优化的问题是缺乏深入的材料性能分析和实现,无法开发合适的数据库。为此,对所选材料采用不同的试样进行有限元分析,并结合推理结果对材料的性能进行研究。所得结果可用于根据边界条件选择合适的材料进行材料优化。拓扑优化算法表明了所得结果的合理应用。提出了一种基于几何活动点和非活动点的物理算法的3D打印方法。因此,可以排除不活跃点,并可以减少材料的使用。

Pub Date : 2018-11-01 DOI: 10.1109/AMCON.2018.8614819
Wen-Chi Lu, L. Duan, YiSheng Cai
To keep the proper orientation of the satellite is an essential issue for most space missions. However, tumbling motion of a satellite after separation from the launcher is inevitable and thus the de-tumbling is the first task of the attitude control system of a satellite. Cubesats, one of the nano-class satellites, are defined by Calpoly with masses less than 10kg. A team in National Formosa University is developing a 2-U Cubesat, named as NUTSat, to promote the aviation safety. The cubesat will carry a ADS-B receiver as the main payload to collect the flight information of civil aircraft beneath the orbit. An attitude control system of the cubesat is designed to perform the detumbling and attitude control and keep the ADS-B antenna towards to the earth. The cubesat has two magnetic torquers and one coil to interact with the earth’s magnetic field to generate proper torques to change the attitude. A three-axis magnetic sensor is used to estimate the satellite’s orientation. At this phase, the de-tumbling has been validated by simulation. Further attitude pointing controller design is undergoing.
保持卫星的正确方向是大多数太空任务的一个基本问题。然而,卫星在与发射体分离后的翻滚运动是不可避免的,因此反翻滚是卫星姿态控制系统的首要任务。立方体卫星是纳米级卫星之一,由Calpoly定义为质量小于10公斤。台湾国立台塑大学(National Formosa University)的一个团队正在开发一种名为NUTSat的2-U立方体卫星,以促进航空安全。该卫星将携带ADS-B接收机作为主要有效载荷,用于收集轨道下民用飞机的飞行信息。设计了卫星姿态控制系统,实现了卫星的坠落和姿态控制,使ADS-B天线保持对地方向。立方体卫星有两个磁扭矩器和一个线圈,与地球磁场相互作用,产生适当的扭矩来改变姿态。一个三轴磁传感器被用来估计卫星的方向。在此阶段,通过仿真验证了去翻滚的有效性。进一步的姿态指向控制器设计正在进行中。

For virtual reality, one of the hottest industries today, which applications can be seen in many fields. There are already many cases in education for applying virtual reality effects to assist teaching and achieve better learning results. This study classifies the content of interior design courses through the implementation process of knowledge engineering. For considering the effects and content to be presented, the commercial software Unity and Holobuilder are used to implement the virtual reality. The results show that the knowledge engineering process introducing can effectively explore the content to be considered when making virtual reality, such as the organization of knowledge content, the setting of interaction methods, the link between objects and the setting of restrictions. The virtual reality scene is the teaching content of the color matching and application in the space, so that the learner can improve the user’s ability to match the color of the space through this system. This study of the thesis is only preliminary preparations. In the future, more complete scenarios and content creation can be achieved through commercial applications, which will effectively help learners to improve learning outcomes in a new way.","PeriodicalId":438307,"journal":{"name":"2018 IEEE International Conference on Advanced Manufacturing (ICAM)","volume":"232 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116323409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, a polymeric Bragg grating is covered on a D-shaped single mode optical fiber, which is side-polished on a convex polymeric structure formed on a glass substrate. The Bragg grating is transferred from a photoresist, formed by using holographic interference lithography, onto a glass substrate by employing the micro-electro-mechanical systems (MEMS) technologies. The optical characteristics of the filter are measured by using a tunable laser.
