Arcturus user's guide

This document describes the Arcturus programming environment, a first realization of an advanced programming environment based on the programming language Ada. It is the first environment that supplies interactive, "statement (or declaration) at a time" execution of Ada program fragments

An FPGA-based infant monitoring system

We have designed an automated visual surveillance system for monitoring sleeping infants. The low-level image processing is implemented on an embedded Xilinx’s Virtex II XC2v6000 FPGA and quantifies the level of scene activity using a specially designed background subtraction algorithm. We present our algorithm and show how we have optimised it for this platform

An Annotated Bibliography and Performance Commentary of the Works for Concert Band and Wind Orchestra by Composers Awarded the Pulitzer Prize in Music 1993-2015, and a List of Their Works for Chamber Wind Ensemble

The purpose of this document is to assemble into one resource the concert band, wind orchestra, and chamber wind ensemble compositions of the 23 composers who were awarded the Pulitzer Prize in Music between 1993 and 2015. The Pulitzer Prize in Music is given annually to an American composer in recognition of distinguished achievement in composition of a work that received its premiere during the previous year. Timothy Mahr completed this study on composers who received the Prize from 1943 to 1992. This is a continuation and replication of that study, following Mahr’s procedures. A brief biographical sketch will be given for each composer, followed by a complete listing of their works for concert band, wind orchestra, and chamber wind ensembles of five to fourteen performers. Works for concert band and wind orchestra will be annotated, including available information on the premiere, instrumentation, publisher and date of publication, availability, level of difficulty, duration, and commission. Each of these works will be given a brief performance commentary and will include a selective bibliography and selective discography. Works for chamber wind ensembles will be listed by composer, title, and number of instrumental performers, but will not be annotated. There are 348 works in total to be considered in this research. The 257 chamber wind ensemble works account for 74% of the total, with the 91 works for concert band and wind orchestra comprising 26% of the total number. Second-party transcriptions of works originally for other genres are listed in the appendices, but not annotated or included in the number of total works. This study suggests that conductors should entreat these distinguished composers to continue to write for the wind band medium and identifies works that have been overlooked in scholarly research or have not been professionally recorded

Division of Maternal Fetal Medicine

The Division of Maternal Fetal Medicine at the University of Iowa provides care for women with medical, surgical, and obstetrical complications of pregnancy. The patients are cared for in a series of clinics, including the High Risk Obstetric Clinic and the multidisciplinary Fetal Diagnosis and Therapy Unit. The majority of level II scans, anomaly consultations, and interventional fetal procedures in Iowa are performed by this unit

Division of Maternal-Fetal Medicine

The Division of Maternal-Fetal Medicine presently includes maternal-fetal specialists. They are: Kimberly K. Leslie, MD (Department Head), Stephen K. Hunter, MD, PhD, (Division Director), Jennifer R. Niebyl, MD, Asha Rijhsinghani, MD, and Mark Santillan, MD, and Jennifer Krupp, MD. Dr. Roger A. Williamson, double boarded in Genetics and Obstetrics, is an Emeritus member of the Division

Space Traffic Management Concepts Leveraging Existing Frameworks

Leveraging existing U.S. regulatory frameworks, as well as international organizations, will dramatically shorten the time needed to develop an effective Space Traffic Management concept. Both the Department of Defense and the Department of Transportation have been working with the U.S. Congress to define and develop a Space Traffic Management concept that will allow the Office of Commercial Space Launch to begin a new mission that will help to ensure the safety and resilience of the space domain. Outside observers can easily see forward progress toward this, still, undeveloped concept. This paper explores potential final U.S. Space Traffic Management concepts that would be consistent with on-going U.S. Government work using existing frameworks and regulatory templates. Further, this paper explores far-term expansion of the U.S. Space Traffic Management concept in the international arena by extrapolating existing concepts and using existing organizations. This paper argues that the international, “top-down”, approach hinders the process of developing a usable global Space Traffic Management concept and, by taking a leadership role, the U.S. can develop a useful concept for U.S. entities that can be expanded to an international audience more easily and in a manner much more palatable to non-U.S. entities. This paper further explores the benefits to the commercial, civil, and military sectors by using the “bottom-up” approach and discusses recent international venues in which this concept was used to explore space domain resilience

Standup of the Joint Interagency Comined Space Operations Center

On 23 June 2015, Deputy Defense Secretary Bob Work announced the development of the Joint Interagency Combined Space Operations Center (JICSpOC) and a backup for the Joint Space Operations Center (JSPoC). Initial standup for testing and experimentation is scheduled for 1 October 2015 with an anticipated initial operational capability of 1 May 2016. After development is completed, the JICSpOC will officially be declared the backup to the JSpOC. The JICSpOC is designed to created unity of effect and information in space operations among the Department of Defense, Intelligence Community, Interagency, allied, and commercial satellite industries. The initial need for the JICSpOC is to ensure the National Security Space Enterprise meets and out-paces emerging and advanced space threats and continues to provide vital information, capabilities and effects for national leadership, allies, partners and the Joint Force. The JICSpOC will enhance the deterrent posture of National Security Space by further demonstrating the United States is prepared should an adversary attack our space capabilities and thereby enhances the space contributions to national security. The center will have the capability to develop, test, validate and integrate National Space Systems Tactics, Techniques and Procedures. The Department of Defense is committed to creating space resiliency and is working with the Intelligence Community to build the JICSpOC to take a giant leap forward toward that goal. While the details on the JICSpOC are still being worked out, the US Government recognizes that our nation’s space architecture faces increasing threats. It is important that the Department of Defense and Intelligence Community work together to address those threats and better integrate space capabilities. Together they will develop innovative approaches to space control

Maximum fidelity retransmission of mirror symmetric qubit states

In this paper we address the problem of optimal reconstruction of a quantum state from the result of a single measurement when the original quantum state is known to be a member of some specified set. A suitable figure of merit for this process is the fidelity, which is the probability that the state we construct on the basis of the measurement result is found by a subsequent test to match the original state. We consider the maximisation of the fidelity for a set of three mirror symmetric qubit states. In contrast to previous examples, we find that the strategy which minimises the probability of erroneously identifying the state does not generally maximise the fidelity
