Small Satellite Conference

The multi-sensor micro-satellite imager (MSMI) programme is developing an imager suitable for microsatellites, with multi-spectral, hyperspectral and video detectors on the same focal plane of a single telescope. It also contains the mass memory and high speed data compression capability to store any combination of the above sensor outputs on board. The imager is designed as a standard payload for the African Resource Management (ARM) satellite constellation and will be test flown as part of the ZASat programme (as part of the South African Space programme). Consortium partners include universities, private companies and research councils in both South Africa and …

Accurate Battery Performance Modelling: The Key To Accessing A Truly Responsive Modular Small-Cell Concept , Chris Pearson, Nick Russel, Carl Thwaite

Small Satellite Conference

The AEA Technology (AEA) Small Cell concept allows an infinite range of battery sizes to be built up using the minimum amount of re-qualification. Furthermore, an extensive rolling stock of cells is held at AEA to ensure that future demand can be met without the need for programme delays due to cell manufacture lead-time. Batteries can be composed of modular blocks so that energy storage systems can be built up from common building bricks. This eliminates the need for qualification and minimises recurring battery cost. Such features have captured the mood of the small satellite community in the quest for …

Low Power High-Speed Radiation Tolerant Computer, David Czajkowski, Praveen Samudrala, Manish Pagey, David Strobel

Small Satellite Conference

This paper presents a new concept of building a high performance, radiation hardened computer from Commercial-Off-The-Shelf (COTS). We discuss the underlying radiation mitigation technologies used, and demonstrate their (radiation-tolerance) capabilities by citing the radiation test results. Hardness against Single Event Upsets (SEU) for COTS microprocessors is achieved using Time-Triple Modular Redundancy (TTMR). Single Event Functional Interrupts (SEFI) of the microprocessors are being mitigated with an auxiliary Hardened Coreä (H-Core) chip. The other on-board chips used are a combination of space qualified, radiation hardened COTS parts. A flight unit of the computer based on the above mentioned technologies, Proton 100k, was …

Formation Flying Demonstration Missions Enabled By Canx Nanosatellite Technology, Eric Caillibot, Cordell Grant, Daniel Kekez

Small Satellite Conference

Two nanosatellite missions that lay the groundwork for satellite formation flying are being realized at the University of Toronto Institute for Aerospace Studies, Space Flight Laboratory (UTIAS/SFL). Such an undertaking has never before been attempted with satellites of this size (< 10 kg). These missions will establish the core technologies necessary for formation flying endeavours at any scale, while capitalizing on the low-cost nature and rapid design cycle of nanosatellites. The key technologies being developed for the nanosatellite missions are nanosatellite propulsion, centimeter-level position determination, and active, three-axis attitude control. The first mission, CanX-2, currently nearing completion, will evaluate the core subsystems listed above. Its planned launch is scheduled for mid-2006. CanX-2 will be followed by a dual satellite mission, CanX-4 and -5, to be launched in 2008, that will build upon the experience gained from CanX-2 and demonstrate actual formation flying. This paper describes the design of CanX-2 and the practical lessons learned to date that can be applied to CanX-4 and -5. The objectives and preliminary mission profile for CanX-4 and -5 are also outlined.

System-Level Mitigation Of Sefis In Data Handling Architectures, A Solution For Small Satellites, Shazia Maqbool

Small Satellite Conference

We describe a fault-tolerant architecture designed to enhance commercial-off-the-shelf (COTS) device-based space-system reliability, and to provide automated system recovery, in the presence of radiation-induced functional errors. The architecture is primarily aimed at cost-effective “small satellite” systems, where very limited mass, volume and power resources preclude the use of multiple-redundant system-based architectures. Our architecture is based on the concept of a fast data network interlinking all units of the data handling subsystem to an intelligent supervisor node. The supervisor monitors status messages from the units and intervenes when the state of a unit does not match expectations or messages stop arriving. …

A Standardized, Distributed Computing Architecture: Results From Three Universities, Michael Swartwout, Christopher Kitts, Pascal Stang, Glenn Lightsey

Small Satellite Conference

At the 16th AIAA/USU Conference on Small Satellites, researchers at Santa Clara University (SCU) proposed a distributed computing architecture for small or multi-spacecraft missions. This architecture extended existing I2C, Dallas 1-wire and RS232 data protocols and was adaptable to a number of microcontrollers. Since then, that architecture has been implemented on six university-class space missions at three different universities. As “early adopters”, these universities had the typical challenges of working with a new, evolving standard and adapting the standard to their hardware and mission needs. Each faced additional, program-specific challenges related to project size, scope and infrastructure as well as …

The *.Sat Cubesat Bus: When Three Cubes Meet, Eric Lee, Matthew D’Ortenzio, Stevan Spremo, Belgacem Jaroux, Ignacio Mas, Dan Saldana

A collaborative effort between Stanford University and the National Aeronautics and Space Administration (NASA) begun in 2003 continues today with the primary objective of supporting a NASA Ames Research Center (ARC) biological payload scheduled for launch into orbit aboard a satellite conforming to the International CubeSat Specification authored in 2001. The Stanford portion of the program, named “StarDotSat” (*.Sat), seeks to put forth a standardized spacecraft bus adhering to the CubeSat Specification that provides all necessary services to one or more attached payload modules. The CubeSat specification was the result of a joint effort by the California Polytechnic University, San …

Of Rainbows And Rivers: Lessons For Telecommunications Spectrum Policy From Transitions In Property Rights And Commons In Water Law, Dale B. Thompson

ExpressO

A number of industries utilize the telecommunications spectrum to provide billions of dollars of services. However, some have noted that technological development and implementation of spectrum applications have not progressed as fast in the United States as in other parts of the world To improve technological development, many have recommended significant changes in United States policy of allocating spectrum, some based on a “property rights” approach, and others based on a “commons” approach. This article takes a novel approach to this problem, by applying lessons from our two hundred year history of water law to spectrum policy. Also, instead of …

Extensible Boom-Based Optical System For Nano-Scale Remote Sensing Satellite "Prism" , Yuya Nakamura, Ryu Funase, Masaki Nagai, Akito Enokuchi, Yuta Nojiri, Tsukasa Funane, Fumiki Sasaki, Shinichi Nakasuka

Small Satellite Conference

Intelligent Space Systems Laboratory (ISSL), the University of Tokyo is now developing the nano-scale remote sensing satellite named as "PRISM." This satellite aims at obtaining high resolution Earth images with 30m of ground resolution. Conventional remote sensing satellites have adopted reflective optical system using multiple mirrors to realize long focal length and large aperture. However, such system requires very high stiffness, machining accuracy and thermal management in order to maintain the designed light path. Thus we concluded that common reflective optical system cannot be applied to our nano-satellite, and adopted a totally different concept. PRISM deploys an extensible boom up …

Specific Ige Response To Purified And Recombinant Allergens In Latex Allergy, Viswanath P. Kurup, Gordon L. Sussman, Hoong Y. Yeang, Nancy Elms, Heimo Breiteneder, Siti Am Arif, Kevin J. Kelly, Naveen K. Bansal, Jordan N. Fink

Mathematics, Statistics and Computer Science Faculty Research and Publications

Background

In recent years, allergy to natural rubber latex has emerged as a major allergy among certain occupational groups and patients with underlying diseases. The sensitization and development of latex allergy has been attributed to exposure to products containing residual latex proteins. Although improved manufacturing procedures resulted in a considerable reduction of new cases, the potential risk for some patient groups is still great. In addition the prevalent cross-reactivity of latex proteins with other food allergens poses a major concern. A number of purified allergens and a few commercial kits are currently available, but no concerted effort was undertaken to …

Business Process Outsourcing: An Exploratory Study, David Johnson

LSU New Orleans Theses and Dissertations

This study examines the emergence of Business Process Outsourcing (BPO) in white collar occupations. Recent BPO practices are compared to the offshore outsourcing of production in the context of the shift from Fordist to flexible production. The study considers BPO in light of Harry Braverman's theory of work degradation and whether or not BPO extends the traditional division of labor between conception and execution to higher skilled white collar occupations. An exploratory qualitative approach comprised of informant interviews, a focus group, and literature review was used to analyze how BPO occurs, why it happens, and where it takes place. I …

Colonial Legacies And Development Performance In Africa, Stephanie Burchard

LSU New Orleans Theses and Dissertations

It is often assumed that significant differences existed between Great Britain and France with regards to their respective styles of colonial administration. Some researchers have asserted that this difference in colonial administration has affected post-colonial economic and political development in Africa. This paper offers some theoretical, anecdotal, and econometric evidence questioning the validity of these assumptions. This paper also examines some commonly encountered problems associated with econometric analyses of African development: namely, the availability and reliability of data, and the difficulty in operationalizing and measuring political development in Africa.

Electrodisinfection Of Municipal Wastewater Effluent, Mark Peterson

LSU New Orleans Theses and Dissertations

To avoid the spread of disease from sewage treatment effluents, pathogenic microorganisms present must be destroyed by one or a combination of disinfection methods. Chlorine remains the predominant disinfectant used although it consumes considerable amounts of energy and has associated exposure risks from production, transportation and storage of this poisonous gas. In addition to bacteria and other objectionable microorganisms, color, suspended and colloidal solids also require removal from water for reuse. Aluminum and iron additions have been used to coagulate and remove non-settleable solids. By electrically dissolving aluminum to form solids-bridging aluminum hydroxide, the water itself can also be disinfected …

Exploring The Functional Subtypes Of Relational And Overt Aggression In A Sample Of Detained Girls, Monica Marsee

LSU New Orleans Theses and Dissertations

In the current study, we investigated the association between relational aggression and measures of delinquency and overt aggression in a sample of detained adolescent girls. We also tested the validity of the distinction between reactive and proactive subtypes of relational aggression by testing their independent associations with important emotional, behavioral, personality, social, and cognitive variables that have been studied in past research and found to be important for distinguishing between reactive and proactive overt aggression. Our sample consisted of 58 predominantly African-American (78%) adolescent girls recruited from three juvenile detention centers in the southeastern United States. Participants ranged in age …

Types Of Aggression, Responsiveness To Provocation, And Psychopathic Traits, Luna C. Munoz

LSU New Orleans Theses and Dissertations

Research on the various subtypes of aggression has documented differences in the experience of anger and the expression of angry aggression. Mixed proactive and reactive aggressive individuals exhibit reactive aggression but, unlike reactive aggressive individuals, fail to exhibit angry expressions or physiological arousal. Similar to the proactive group, individuals with psychopathic traits have been found to exhibit emotional underreactivity, and physiological underarousal, while still exhibiting reactive aggression. The present study examined 85 boys (ages 13 to 18) from a detention center. Three groups of aggressive boys were identified via cluster analysis based on the self-report of types of aggressive behavior: …

Evaluation Of An Electro-Disinfection Technology As An Alternative To Chlorination Of Municipal Wastewater Effluents, Maria Elena Pulido

LSU New Orleans Theses and Dissertations

This research evaluated and demonstrated the disinfection efficiency of an electrochemical system for total coliform removal from wastewater effluents after secondary treatment. Four bench scale batch electrochemical cells were assembled and operated in the laboratory: the first electro-disinfection reactor was set with aluminum electrodes, the second with standard 316 stainless steel electrodes, the third one with titanium electrodes, and the fourth one with a standard 316 stainless steel cathode and a titanium anode. During the electro-disinfection process the water sample was placed on the reactor/disinfector to which direct current (DC) was charged. The results showed that total coliform counts in …

Water Quality Study Of Southshore Of Lake Pontchartrain, Maria Carolina Martinez Fernandez

LSU New Orleans Theses and Dissertations

In 2004, a field sampling study was initiated along the southern shoreline area of Lake Pontchartrain in Jefferson Parish, specifically, around Bonnabel Canal (Pumping Station No.1) to identify the effect of urban stormwater discharges on Lake Pontchartrain and to simulate the plume patterns from the Bonnabel Canal. Sixteen sampling stations were selected along the south shore of Lake Pontchartrain. Under dry weather conditions Fecal Coliform values exceeded the limit of 200 MPN/100mL at 3 of 16 stations. Fecal Coliform counts were found to be "wet" weather-dependent and unsuitable for primary contact recreation for at least three to four days following …

Sex And Virtual Reality: Posture And Motion Sickness, Moira Flanagan

LSU New Orleans Theses and Dissertations

It is well established that exposure to virtual motion environments (VME) can elicit postural instability (PI) in addition to motion sickness (MS). While research has found sex differences in motion sickness, the results of experimental studies are equivocal regarding these differences, and previous studies utilizing VME have failed to address the factor of sex differences in terms of hormonal fluctuations, which may also be instrumental in behavioral responses to VME, such as PI. The intent of this investigation was to determine whether exposure to VME, during various phases of the menstrual cycle (premenstrual, permenstrual, ovulation) would reveal sex differences in …

Comparing Different Levels Of Interactivity In The Visualization Of Spatio-Temporal Data, Samara Ebinger

LSU New Orleans Theses and Dissertations

The Internet and other advances in technology have dramatically affected cartography in recent decades and yet these new capabilities have not been adequately evaluated for effectiveness. Are dynamic maps more effective than traditional static paper maps in allowing users to visualize spatio-temporal patterns? How important is a higher level of interactivity in visualizing data? Which format is preferred? To examine these questions, human subject tests were conducted to evaluate different levels of interactivity as represented by 1) a static paper map series; 2) an animated map with 'VCR'-type controls; and 3) a toggle map featuring an interactive temporal legend. Results …
