A Two-Phase Development And Validation Plan For North Dakota's First Spacecraft, Jeremy Straub, Ronald Marsh
A Two-Phase Development And Validation Plan For North Dakota's First Spacecraft, Jeremy Straub, Ronald Marsh
Jeremy Straub
The Open Prototype for Educational NanoSats (OPEN) aims to make space more accessible for educational and other uses by driving down the cost of CubeSat development. This paper presents a tentative plan for the use of two orbital missions as part of a two-phase technology demonstration sequence focusing on raising the technology readiness level (TRL) of OPEN to a level suitable for wide use and adoption. It presents an overview of a two-mission development plan including mission objectives, requirements and constraints. The paper considers how the phase one mission’s spacecraft may serve as a lower-cost platform for some users in …

Conventional quality control of compaction during construction is currently based on an in-situ determination of dry unit weight and moisture content via nuclear procedures, but because this is a localised procedure, poor compaction can often occur. Moreover, with older compacted embankments where few or no records of the control done during construction are available, there is no existing methodology that can help practising engineers assess their post-construction condition. This means that the scope of the nuclear method renders it as inadequate and alternative methods should be considered. The use of shear wave velocity (Vs) surveys (i.e. MASW) to assess the …

Information systems development (ISD), at the core of the information systems discipline, is an evolving field, faced with persistent challenges due to rapidly changing social and business environments as well as emerging technologies and technical infrastructures. Many of these issues have been discussed in the Information Systems Journal (see, for example, Kautz et al., 2007).

Despite ongoing interest in deploying Information and Communication Technologies (ICTs) for sustainable development, their use in climate change adaptation remains under-studied. Based on the integration of adaptation theory and the existing literature on the use of ICTs in development, we present an analytical model for conceptualizing the contribution of existing ICTs to adaptation, and a framework for evaluating ICT success. We apply the framework to four case studies of ICTs in use for early warning systems and managing extreme events in LAC countries. We propose that existing ICTs can support adaptation through enabling access to critical information for decision-making, coordinating …
