Supplemental Material for A Primer on How to Launch an Institutional Repository Successfully.

This is a case study of the implementation of an institutional repository (IR). It is written for academic librarians who are looking for a primer on how to create an IR for their campus. Based upon Marshall University’s research and experience with this process, we present the essential elements needed to construct an institutional repository. Policies and procedures are provided that offer guidelines and checklists to follow for a successful ramp up and launch. A discussion about the value of an IR is followed by ways to secure funding and to implement a basic system that can be scaled up over time. This article mimics the scalable approach to IR implementation by starting with a discussion of the essentials, then addressing more complex IR functions. The investigation and planning stages of IR implementation can take a long time. Marshall University (MU) took (? Months) from the start of the process until the first items placed into the IR went public. It is the intention of this paper to simplify and speed the process for others. Libraries have always collected information from a worldwide marketplace and have disseminated these resources locally. The IR has created a new function for the library by making it practical to acquire locally developed resources and to disseminate them freely worldwide. The institutional repository has altered the traditional role of librarians by empowering us to respond in new ways to the challenges of a new century. This suggests a broader set of implications for the future usefulness and relevancy of the IR as doors open to new partnerships that will strengthen the university and the library’s place within it

Overview of Intelligent Power Controller Development for Human Deep Space Exploration

Intelligent or autonomous control of an entire spacecraft is a major technology that must be developed to enable NASA to meet its human exploration goals. NASA's current long term human space platform, the International Space Station, is in low earth orbit with almost continuous communication with the ground based mission control. This permits the near real-time control by the ground of all of the core systems including power. As NASA moves beyond Low Earth Orbit, the issues of communication time-lag and lack of communication bandwidth beyond geosynchronous orbit does not permit this type of operation. This paper presents the work currently ongoing at NASA to develop an architecture for an autonomous power control system as well as the effort to assemble that controller into the framework of the vehicle mission manager and other subsystem controllers to enable autonomous control of the complete spacecraft. Due to the common problems faced in both space power systems and terrestrial power system, the potential for spin-off applications of this technology for use in micro-grids located at the edge or user end of terrestrial power grids for peak power accommodation and reliability are described

Simulation and Control Lab Development for Power and Energy Management for NASA Manned Deep Space Missions

The development of distributed hierarchical and agent-based control systems will allow for reliable autonomous energy management and power distribution for on-orbit missions. Power is one of the most critical systems on board a space vehicle, requiring quick response time when a fault or emergency is identified. As NASAs missions with human presence extend beyond low earth orbit autonomous control of vehicle power systems will be necessary and will need to reliably function for long periods of time. In the design of autonomous electrical power control systems there is a need to dynamically simulate and verify the EPS controller functionality prior to use on-orbit. This paper presents the work at NASA Glenn Research Center in Cleveland, Ohio where the development of a controls laboratory is being completed that will be utilized to demonstrate advanced prototype EPS controllers for space, aeronautical and terrestrial applications. The control laboratory hardware, software and application of an autonomous controller for demonstration with the ISS electrical power system is the subject of this paper

IRresistable: How an IR (Institutional Repository) can improve library collections while preserving the past

Marshall University’s IR team will discuss the creation, progress, and benefits of the Marshall Digital Scholar, an online institutional repository. There will be time for libraries, large and small, to ask questions about digital collecting and digital projects
