Commercial Space Situational Awareness (Ssa) Capabilities And Their Benefits For Civilian Space Traffic Management (Stm), Mark A. Skinner

Space Traffic Management Conference

Paralleling (but lagging) satellite development, SSA, long the sole domain of sophisticated militaries, now includes commercial providers. These commercial capabilities, identified as beneficial to the sustainable use of outer space[1], have demonstrated technical sophistication sufficient to positively contribute to the mitigation of satellite interference and provide actionable SSA information. Utilizing small optical telescopes, these entities are able to determine the orbits of objects in the geosynchronous orbit (GSO) to sizes as small as 1 m², with measured positional uncertainties of 10s of meters, on the order of the size of a modern communications satellite. These techniques …

Spaceways: Airspace In Outer Space, Scott Haeffelin

Space Traffic Management Conference

Forecasted future demand in space travel is driving the need for the development of space traffic management. Currently, orbital space traffic is mostly unregulated with internationally agreed upon best practices and self-interest driving space operators to avoid collisions with other spacecraft. This paper explores the future of space travel by presenting a concept of creating “airspace in space” or spaceways to manage the ever growing volumes of space traffic. Spaceways are analogous to airspace for aircraft with the goal of increasing levels of safety and reducing probabilities of collision. These goals can be achieved by creating traffic rules, defining valuable …

Space Analysis And Research Centers (Sparcs) For Ssa Data And Analytics, Phillip Cunio, Brien Flewelling

Space Traffic Management Conference

Widespread use of massive data and increasing reliance on spaceborne infrastructure are two of the emerging megatrends of the early 21^st century. However, both come with liabilities: movement and processing of large data volumes is very expensive, and reliance on spaceborne infrastructure adds risk that problems in the still incompletely-understood space domain might cause work disruptions.

ExoAnalytic proposes the use of Space Analysis and Research Centers (SpARCs) as a way to begin addressing both these issues. A SpARC is a facility which integrates volumes of data collected on satellites, centrally analyzes it, and makes available resulting useful information. The …

Projecting Air Traffic Impact Of Blocked Airspaces, Amal Srivastava, Neil Gahart

Space Traffic Management Conference

FAA frequently blocks strategically located airspaces to ensure operational safety in the vicinity of hazardous operations such as space launches and military exercises. As demand for access to airspace continues to rise, the need for, and the impact of blocked airspaces is likely to grow. Users such as space operators have no advanced insights into potential NAS impact of airspaces blocked due to their operations, nor do they possess ways to minimize it. This paper presents a model that would give users this insight. The model estimates levels of air traffic likely to intersect arbitrary airspace volumes on a daily …

Air Traffic Impact Analysis Design For A Suborbital Point-To-Point Passenger Transport Concept, Tanja Luchkova, Sven Kaltenhaeuser, Frank Morlang

Space Traffic Management Conference

Space flight activities are growing on an international level, thereby creating an evident need for a safe and efficient integration of space vehicle operations into the air traffic system. For concepts like very high-speed intercontinental passenger transport via suborbital point-2-point flights, as it is proposed by the DLR SpaceLiner, this integration issue is becoming especially relevant. As part of a case study approach to analyse the effects of space vehicle operations on air traffic and to evaluate mitigation strategies and optimized ATM integration, a traffic impact analysis has been prepared and conducted for the SpaceLiner return trajectory towards a European …

Examining Time To Evacuate Dynamically Activated Aircraft Hazard Areas, Zheng Tao, Granghuai Wang, Ashley G. Williams, Jon L. Semanek, Jonathan L. Schwartz

Space Traffic Management Conference

The growth in launch and reentry operations in the National Airspace System (NAS) presents the Federal Aviation Administration (FAA) with the challenge of integrating them more efficiently while also minimizing effects on other NAS users and maintaining safety. Currently, to maintain safety and account for unforeseen events such as vehicle breakup, the FAA segregates large amounts of airspace, called Aircraft Hazard Areas (AHAs), from traditional NAS users during launch and reentry operations. In order to minimize effects on NAS users, some AHAs during reentry are dynamically activated only if an unexpected event occurs. If a dynamic AHA is activated, then …

Common Management Gaps In The Life Cycle Of Digitized Objects, Jocelyn Wehr

Central Plains Network for Digital Asset Management

Presented from the perspective of someone responsible for creating the digital objects that will eventually be included in a digital preservation program, this poster session will identify common issues that make the management and preservation of digital objects more challenging. Digital preservation needs to be talked about within the digitization workflow, because it takes a lot of work to produce the best digital objects possible. We are often focused on the immediate use of the digital objects and less focused on their long-term use. Even with best practices in mind, there is often an immediate need (patron orders, for example) …

Numbers, Numbers, Numbers—Is It Working?! Meaningful Measurement Of Digital Collections, Allison Ringness

Central Plains Network for Digital Asset Management

After a digital project is completed and made available online, the work is not over: digital projects managers must quantify the value of these digital collections. There are a plethora of tools to measure usage, but inferring value from usage requires careful interpretation of the data. After interpretation, the results must be communicated effectively to administrators. This poster will identify sources of digital collection use data, identify pitfalls in these sources, explore ways to derive meaning from use data, and suggest strategies for communicating value measurements to library administrators.

This poster presentation is the first 15 minutes of video with …

Collaborating Across Workflows: Managing Creative Assets From Legacy Works, Patrice-Andre Prud'homme, Jennifer Hunt Johnson

Central Plains Network for Digital Asset Management

From the perspective of two distinct workflows, this presentation will illustrate how library departments, Digital Collections and Conservation collaborate on the production of digital assets. In essence, both digitization and analog preservation workflows aim to guarantee that collections are easily retrieved and usable. This case study will illustrate two examples. The first one is more linear yet regional; it aims to create digital assets to engage the community by means of crowdsourced transcription. The second one is hands-on, as it addresses the long-term research value of the physical material for use in classrooms by Special Collections. While these workflows may …

Experiments On Column Base Stiffness Of Long-Span Cold-Formed Steel Portal Frames Composed Of Double Channels, H. B. Blum, K. J. R. Rasmussen

CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)

Cold-formed steel haunched portal frames are popular structures in industrial and housing applications. They are mostly used as sheds, garages, and shelters, and are common in rural areas. Cold-formed steel portal frames with spans of up to 30m (100 ft) are now being constructed in Australia. As these large structures are fairly new to the market, there is limited data on their feasibility and design recommendations. An experimental program was carried out on a series of portal frame systems composed of back-to-back channels for the columns, rafters, and knee braces. The system consisted of three frames connected in parallel with …

Experimental Investigation Into Steel Storage Rack Beam-To-Upright Bolted Connections, Liusi Dai, Xianzhong Zhao, Chong Ren

CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)

For unbraced steel storage racks, the down-aisle stability depends largely on the performance of beam-to-upright connections and column bases. Boltless connections are generally used in order to make rack structures easy to assemble and feasible to adjust the storey height. Recently, storage racks are designed to carry large amounts of goods and they are therefore raise a considerable height, which makes the improvement of the structural stability to be sufficiently important. Under the circumstances, tab-connected beam-to-upright connections with bolts are gradually used in steel storage racks. Compared with boltless connections, the stiffness, strength and ductility of the bolted connections are …

Reduced Order Models For Profiled Steel Diaphragm Panels, G. Bian, S. Torabian, B. W. Schafer

CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)

The objective of this paper is to provide progress on development and validation of reduced order models for the in plane strength and stiffness of profiled steel panels appropriate for use in structural models of an entire building. Profiled steel panels, i.e, metal deck, often serve as a key distribution element in building lateral force resisting systems. Acting largely as an in-plane shear diaphragm, metal deck as employed in walls, roofs, and floors plays a key role in creating and driving three-dimensional building response. As structural modeling evolves from two-dimensional frameworks to fully three-dimensional buildings, accurate and computationally efficient models …

This paper summarizes research on the cross-aisle stiffness and strength of industrial cold-formed steel rack upright frames for loads in cross-aisle direction. Tests were carried out at the Universitat Politècnica de Catalunya, Barcelona, Spain on joints as well as entire upright frames. A possible rather simple analysis procedure is developed and described.

Characterizing The Load Deformation Behaviour Of Steel Deck Diaphragms, P. O'Brien, S. Florig, C. D. Moen, M. R. Eatherton

CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)

Lateral loads flow through a building’s horizontal roof and floor diaphragms before being transferred to the vertical lateral force resisting system (e.g. braced frames, moment frames or shear walls). These diaphragms are therefore a critical structural component in the resistance of lateral loads. A review of the literature shows that a large number of experimental programs have been performed to obtain the in-plane load-deformation behavior of steel deck and concrete on steel deck diaphragms. The tested diaphragm behavior was found to be dependent on a set of factors including loading protocol, fastener type, fastener size and spacing, and more. There …

Development Of A Method To Generate A Simplified Finite Element Model For An Electrical Switchboard Cabinet, Edwin Lim, Barry J. Goodno, James I. Craig

CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)

Electrical switchboards are one of the key pieces of equipment used in operations of most critical facilities such as hospitals and emergency services buildings. Unfortunately, past observations have shown that the switchboard cabinet and its contents may be vulnerable to damage or failure during an earthquake. An electrical switchboard cabinet is a complex structure typically constructed using cold-formed steel frame members enclosed by steel panels and containing a variety of switchgear and bus bars. The panels are usually fastened to the steel members by screws, and the steel members are connected together by bolts or screws. The structural behavior of …

An Improved Two-Stage Seismic Analysis Procedure For Mid-Rise Buildings With Vertical Combination Of Cold-Formed Steel And Concrete Framing, X. Yuan, L. Xu

CCFSS Proceedings of International Specialty Conference on Cold-Formed Steel Structures (1971 - 2018)

Presented in this paper is an improved two-stage analysis procedure for evaluating the seismic load of the mid-rise buildings with vertical combination of cold-formed steel and concrete framing. By comparing the improved procedure to the one prescribed in ASCE 7, it is found the stiffness requirement of the two-stage analysis procedure stated in ASCE 7 may be over-relaxed, which may consequently result in the underestimation of the base shear of the upper structure in certain cases. Furthermore, the lateral load at the top storey of the upper structure evaluated by ASCE 7 two-stage analysis procedure may also be considerably underestimated. …
