The main objective of the Offshore Code Comparison Collaboration Continuation, with Correlation (OC5) project, is validation of aero-hydro-servo-elastic simulation tools for offshore wind turbines (OWTs) through comparison of simulated results to the response data of physical systems. Phase III of the OC5 project analyzes the Senvion 5M wind turbine supported by the OWEC Quattropod from the alpha ventus offshore wind farm. This paper shows results of the verification of the OWT models (code-to-code comparison). A subsequent publication will focus on their validation (comparison of simulated results to measured physical system response data). Based on the available data, the participants of Phase III set up numerical models of the OWT in their simulation tools. It was necessary to verify and to tune these models. The verification and tuning were performed against an OWT model available at the University of Stuttgart - Stuttgart Wind Energy (SWE) and documentation provided by Senvion and OWEC Tower. A very good match was achieved between the results from the reference SWE model and models set up by OC5 Phase III participants. © Copyright 2018 ASME.

10.4.0 Panel 10.4.0: U.S. OSD Systems of Systems engineering Guide: Status Report & INCOSE Support

引用

INCOSE International Symposium 2014年第1期17卷

作者： Kristen Baldwin Dr. Charles Dickerson Dr. Abe Meilich John Osterholz Malcolm Touchin Dr. Steve Bratt Panelist Deputy Director Office of the Secretary of Defense (OSD) Software Engineering and System Assurance Office of the Deputy Under Secretary of Defense Acquisition and Technology Chair INCOSE Architecture Working Group (AWG) INCOSE AWG Leadership Team former Director BAE Systems Architecture and Interoperability for the DoD Chief Information Officer Technical Manager Systems Engineering Innovation Centre (SEIC) Loughborough University CEO W3C (invited) World Wide Web Consortium (W3C)

In May 2006, a task was issued by the U.S. Deputy Under Secretary of Defense for Acquisition and Technology (DUSD (A&T)) to develop a Systems of Systems engineering Guidebook. The Office of the Secretary of Defense (OSD) convened a small group of Government, Industry and Academia, and selected the Stevens Institute of Technology to lead the project. During the summer and autumn of 2006, the International Council on Systems engineering (INCOSE) was honored to be invited to provide a global representation of the systems engineering community in support of the OSD writing of a Systems of Systems, Systems engineering (SoS SE) Guide. On 22 December 2006 the draft SoS SE Guide, version 0.9, was released for review and use by the systems engineering community. Industry and academia have been asked to submit their comments as part of the effort to pilot the recommendations in the Guide. In 2007, OSD has been actively engaging a sample of DoD SoS programs to pilot the Guide, especially with respect to the 16 OSD SE processes. The responses will become part of the first update to the Guide. At this panel, OSD will present the background and motivation for writing the Guide, along with an update on the pilot. Both OSD and INCOSE will discuss their insights. As part of the broad SE community review, the Guide will also be viewed from the UK perspective of Capabilities Based Acquisition. Looking to the future, the concepts and practices of Net Centricity, Network Enablement of Capabilities, and Semantic Web will be considered and how they might be more deeply integrated into future versions of the Guide. This panel will provide opportunities for INCOSE to continue to work with OSD and collaborate on SoS SE.

The U.S. Coast Guard's multimission patrol boats are rapidly approaching the end of their useful service life. Conventional and advanced designs are being assessed as potential replacements. The paper presents the conventional design which is based on modern, well-proven patrol boat design practices and technologies. The principal features and performance characteristics of the design are highlighted. Also described are the specific mission requirements, the general design philosophy, and important design objectives including seakeeping performance, survivability, habitability and safety. Other objectives discussed in the paper include improved producibili-ty and reduced maintenance requirements to minimize life cycle cost.

最近,天然异质结(PbSe)_(5)(Bi_(2)Se_(3))_(6)在理论上预测并实验证实为拓扑绝缘体.本文通过高压原位量子调控在(PbSe)_(5)(Bi_(2)Se_(3))_(6)中成功引入超导电性.当压力增加到10 GPa时,超导电性突然出现,T_(c)约为4.6 K,随后T_(c)急剧下降.值得注意的是,当进一步施加压力到30 GPa以上时,出现了一种新的超导态,且T_(c)直到本实验最高压力仍未饱和.结合XRD和拉曼光谱,我们认为(PbSe)_(5)(Bi_(2)Se_(3))_(6)中两个超导态的出现与压力诱导的结构相变有关.拓扑异质结压力下出现新的量子态,为进一步研究拓扑和超导的关系提供了一个良好的平台.

Natural spline interpolation and exponential parameterization for length estimation of curves

AIP Conference Proceedings 2017年第1期1863卷

作者： R. Kozera M. Wilkołazka 1Warsaw University of Life Sciences - SGGW Faculty of Applied Informatics and Mathematics Nowoursynowska str. 159 02-776 Warsaw Poland 2John Paul II Catholic University of Lublin Faculty of Mathematics Information Technology and Landscape Architecture Konstantynó w str. 1H 20-708 Lublin Poland 3The University of Western Australia School of Computer Science and Software Engineering 35 Stirling Highway Crawley W.A. 6009 Perth Australia

This paper tackles the problem of estimating a length of a regular parameterized curve γ from an ordered sample of interpolation points in arbitrary Euclidean space by a natural spline. The corresponding tabular parameters are not given and are approximated by the so-called exponential parameterization (depending on λ ∈ [0, 1]). The respective convergence orders α(λ) for estimating length of γ are established for curves sampled more-or-less uniformly. The numerical experiments confirm a slow convergence orders α(λ) = 2 for all λ ∈ [0, 1) and a cubic order α(1) = 3 once natural spline is used.

Wengcao Village, listed in the fourth batch of traditional villages in China, is a remote Miao village which built in a landslide-prone risk, and always at the risk of geological hazard-prone area. In order to solve the contradiction between the protection of traditional villages and the economic development of traditional villages, on the basis of environmental behavior, spatial behavior and complex theory, the author combined with the investigation. For the first time, a four-dimensional collaboration model of expert supervision, enterprise leadership, government guidance, and public participation was creatively proposed to ensure the replication and relocation of traditional villages. Aim to ensure the smooth progress of the replication and construction of traditional villages, the current popular neural network prediction model and reinforcement learning multi-agent model are combined to build a replication and construction decision model and its optimize to avoid possible future risks.

We describe the problem of estimating a length of a regular parameterized curve from an ordered sample of interpolation points in arbitrary Euclidean space by modified complete spline. The corresponding tabular parameters are assumed to be unknown and are approximated by the exponential parameterization (controlled by the parameter λ ∈ [0, 1]). In this paper the numerical verification of asymptotic orders α(λ) in length estimation is performed for curves sampled more-or-less uniformly. The numerical experiments confirm a slow linear convergence orders α(λ) = 1 for all λ ∈ [0, 1) and a quartic order α(1) = 4 once modified complete spline is used.
