ADVANCED RANGE TELEMETRY DYNAMIC MEASUREMENT LISTSLuten, Robert H., Diekmann, Vernon 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / A typical telemetry system for aircraft flight-testing transmits one or several data streams to the ground for real-time display and analysis, and also records the same stream onboard for later playback. During test operations, only a fraction of the available data is used at any given time for real-time display or analysis. More efficient use of the RF channel could be realized if only the data needed for the current test point is transmitted, rather than the entirety of the data. Intelligent selection of a subset of the data stream can provide large reductions in the required telemetry downlink bandwidth. As one of the Advanced Range Telemetry (ARTM) On-Board Data Management (OBDM) initiatives, a prototype on-board data selection subsystem is being developed and demonstrated. The demonstration utilizes COTS telemetry workstations to the maximum extent possible and includes “plug-in” data requestor, selection, and server components to implement the added DML functionality. A significant objective of the OBDM/DML project will be to validate RF channel models to help minimize the amount of flight-testing necessary to validate the DML concept. This paper will discuss the OBDM/DML architecture, integration of several custom components with the COTS portions of the ARTM “test bench”, and the current status of the OBDM/DML development and test program.

PCI BASED TELEMETRY DECOMMUTATION BOARDJerome, Chris, Johnson, Edward, Sittler, Arthur, Wainwright, Ross 10 1900 (has links)
International Telemetering Conference Proceedings / October 26-29, 1998 / Town & Country Resort Hotel and Convention Center, San Diego, California / The Space Sensing & Vehicle Control Branch of the Air Force Research Laboratory and Voss Scientific, Albuquerque, NM, are developing an advanced PC and COTS-based satellite telemetry processing, analysis and display system known as the PC-Satellite Telemetry Server (PC-STS). This program grew out of a need to develop less expensive, more capable, more flexible, and expandable solutions to the satellite telemetry analysis requirements of the Air Force. Any new system must employ industry standard, open architecture, network and database protocols allowing for easy growth and migration to new technologies, as they become available. Thus, the PC-STS will run on standard personal computers and the Windows NT operating system. The focus of this work and this paper is the Telemetry Server component, and in particular, the custom-built decommutation board. The decommution board will be capable of processing frame formatted and CCSDS packet telemetry. It will be capable of fully decommutating telemetry data, converting raw data to engineering units, and providing this data to the Telemetry Server host. Time tagged engineering units or minor frames of telemetry will be transmitted to the Telemetry Server processor via on-board memory buffers. The decom board uses the PCI bus, programmable DSPs, considerable on-board memory, and a SCSI bus for local archiving. This paper presents the general architecture of the PC-STS, and discusses specific design considerations. These include trade-offs made during the design of the board’s hardware and software, operational specifications, and graphical user interfaces to program, monitor, and control the board.

An On-Board Instrumentation System for High-Rate Medium Caliber ProjectilesBukowski, Edward, Don, Michael, Grzybowski, David, Harkins, Thomas 10 1900 (has links)
ITC/USA 2015 Conference Proceedings / The Fifty-First Annual International Telemetering Conference and Technical Exhibition / October 26-29, 2015 / Bally's Hotel & Convention Center, Las Vegas, NV / The U.S. Army Research Laboratory developed an on-board telemetry instrumentation system to obtain measurements of the in-flight dynamics of medium caliber projectiles. The small size, high launch acceleration, and extremely high spin rates of these projectiles created many design challenges. Particularly challenging were the high spin rates, necessitating the development of a data compression scheme for solar sensors. Flight tests successfully captured data for spin rates exceeding 1000 Hertz (1 kHz).

The effect of a supreme court opinion outside the judicial system : an analysis of Brown v. Board of Education and the American SouthAllen, Neal Robert 01 June 2010 (has links)
This dissertation seeks to describe and explain the connection between The Supreme
Court and politics outside of the judicial system. It is a case study of the reaction to the
Brown v. Board of Education integration decision in the American South. I apply a
theoretical model of “judicialization,” arguing that when courts affect politics outside of
the judicial system, they reshape politics to resemble the adversarial legal system,
sparking polarized conflict and causing non-judicial political actors to make arguments in
the form of constitutional doctrine. Analyzing editorials and letters to the editor from
Southern newspapers, I show that debate after Brown was characterized by appeals to
constitutional principles, and that Brown increased the salience of segregation in schools
as a subject of political debate. I also supplement my Southern newspaper data with data
from African-American newspapers and analyze Southern elections in the periods
immediately before and after the education integration decision to assess the impact of
the Court’s education decision on both voters and candidates. / text

Board of directors’ relationship to environmental sustainability: Differences between insiders and outsiders : A study of inside and outside board members’ cognition and reasoning when engaging in environmental sustainability issuesÖstberg, Joel, Gunningberg, Jonas January 2014 (has links)
The aim of this study is to investigate how inside and outside directors differ in their cognition and reasoning in regards to environmental sustainability issues. The theoretical background derives from a cognitive view and Stakeholder theory. The paper is further based on current research regarding insiders’ and outsiders’ relationship to environmental sustainability. In order to capture the cognition and reasoning of insiders and outsiders, a Think-aloud study was conducted, interviewing a total of 20 board members in the food industry. Results from this study showed that, when faced with environmental issues, outsiders are more likely to request, repeat, ponder as well as clarify the information given. Secondly, outsiders are more likely to consider a long-term perspective. Thirdly, outsiders are more likely to consider an environmental view. Lastly, both insiders and outsiders use analogical reasoning when contemplating around environmental issues. However, insiders are more likely to draw experience from their current position or company while outsiders are more likely to draw experience from outside their current position or company when solving environmental issues.

Constructing the military landscape : the Board of Ordnance maps and plans of Scotland, 1689-1815Anderson, Carolyn J. January 2010 (has links)
This thesis examines the mapping of eighteenth-century Scotland in relation to the British state’s imperatives to know the spaces of the nation. It examines the idea of the ‘military landscape’—that conjunction of forts, roads, and barracks—represented and constructed by the military engineers, surveyors, and draughtsmen of the Board of Ordnance between 1689 and 1815. In total, 940 maps constitute the Board of Ordnance ‘archive’ housed mainly in the National Library of Scotland, the British Library, the National Archives (Kew), and the Royal Library at Windsor. The study of the Board of Ordnance military maps of Scotland is considered in relation to the epistemological foundations of map making in the Enlightenment, particular focus being paid to the relations between government institutions and military cartography. The thesis considers how political and military power was embodied in the engineers’ maps and plans. It explores the extent to which the Scottish landscape—especially the Highlands—was an unknown territory demanding intellectual and material civilisation in cartographic form. In its main chapters on forts, movement, and battles, the thesis is organised to reflect the purpose behind the creation of military maps. It includes representations of military activities that consistently had recourse to mapping—fortifying, intelligence, reconnaissance, marching, encamping, and battle—and explains why military maps were conceived thus and how they were used. Fortification cartography dominates the representation of Scottish military landscapes: 73% of the archive constitutes maps, plans, sections, and views of forts, barracks, and coastal batteries; 22% maps associated with military movement; and 5% battle maps. By examining the different genres of military mapping, the thesis offers an evaluation of the Board’s endeavours to rationalise and to codify military cartography in order to bring it in line with wider European practices. This review of the nature and extent of military mapping of eighteenth-century Scotland reveals the practice to be a result of institutional imperatives to assert territorial control rather than simply a cartographic enterprise. In (re)constructing the military landscape, the thesis extends current knowledge of military mapping in eighteenth-century Scotland and provides for the first time a substantive examination of the Board of Ordnance as an agency of state and cartographic authority.

Striking a balance with concussion assessment : use of the Wii balance board to evaluate postural controlCullen, Hilary, M 31 May 2017 (has links)
Background: Concussion assessments rely on a multifaceted approach where evaluation of balance and postural control plays an important role. Following a concussion, 67% of individuals report dizziness as a persistent symptom and 30% experience balance impairments. Studies incorporating the common Balance Error Scoring System (BESS) tool suggest that these impairments return to pre-injury baselines within ten days of incident. In contrast, however, studies incorporating more advanced posturography methods observe significant differences in balance up to one year following injury. While the BESS is consistently associated with low sensitivity and poor reliability scores, advanced posturography systems using force plates are not practical or accessible in most recreational sports environments. Recently, the Wii Balance Board (WBB) has been identified as a potential force plate proxy. Research confirms that the WBB is both valid and reliable in collecting center of pressure data. Thus, the WBB may be useful for investigating post-concussion balance deficits. Objective: The purpose of this study was to investigate the potential utility of a customized WBB program to assess postural balance in an athletic population. The study aimed to assess change in postural balance using the clinical BESS and WBB assessment tools to evaluate balance at fixed intervals during a regular athletic season and following concussion. Design: Prospective partial cohort. Methods: Balance was assessed at baseline, mid-, and post-season. Individuals who sustained a concussion during the study period were further assessed weekly for four weeks post-injury. Results: No significant differences were observed in raw BESS scores across regular season or post-concussion time points. In contrast, significant differences in several WBB outcome measures were observed. In the single stance condition, COPML worsened by 24% and COPT worsened by 9% between baseline and post-season time points (p=.002 and p=.007). In contrast, participants improved by 14% on a timed dynamic task (p=.003) between baseline and post-season time points. Following concussion, only the WBB dynamic outcome measures were found to be statistically significant. A positive trend was observed post-concussion, suggesting that a learning effect exists with the dynamic WBB program. Conclusion: Study results emphasize the importance of considering the progression of athletic season when interpreting baseline and post-concussion balance measurements. Study results support the use of a quantitative balance assessment, such as with a WBB, to improve measurement of static and dynamic postural balance. / Graduate / 0566 / hilarymcullen@gmail.com
