Rendezvous strategy impacts on CTV avionics design, system reliability requirements, and available collision avoidance maneuvers

Rockwell International is conducting an ongoing program to develop avionics architectures that provide high intrinsic value while meeting all mission objectives. Studies are being conducted to determine alternative configurations that have low life-cycle cost and minimum development risk, and that minimize launch delays while providing the reliability level to assure a successful mission. This effort is based on four decades of providing ballistic missile avionics to the United States Air Force and has focused on the requirements of the NASA Cargo Transfer Vehicle (CTV) program in 1991. During the development of architectural concepts it became apparent that rendezvous strategy issues have an impact on the architecture of the avionics system. This is in addition to the expected impact on propulsion and electrical power duration, flight profiles, and trajectory during approach

Hudibras and its literary context

The thesis is approximately 60,000 words in length and is divided into three parts. Part I (Chapters 1-4) deals with Hudibras in relation to seventeenth century literary traditions. Chapter 1 introduces the poem and its author, places Hudibras within its immediate historical context, describes its popularity, and states the problem of determining its genre; several possible solutions to the problem are considered, notably those of seventeenth and eighteenth century writers; "mock-heroic" is defined and adopted. Chapter 2 is a survey: it begins by citing two adverse modern criticisms of Butler's method of ridiculing his principal character, and then sets out to test the justness of them. A number of romances popular in the seventeenth century are described; criticism of them is considered; and several satirical and burlesque works using romantic characters, motifs, and plots are analyzed. Chapter 3 places Hudibras with respect to the works and attitudes described in the previous chapter. The generating circumstances of the first part of the poem are considered in the light of Butler's presentation of them as a romance; Hudibras and Halpho are examined in relation to other mock-knights and squires, especially Don Quixote and Sancho Panza, and Braggadochio and Trompart. Chapter 4 treats Hudibras in connexion with the seventeenth century tradition of classical burlesque, analyzes Butler's treatment of classical themes and characters for the purpose of satire, and in an extended comparison between Hudibras and Gondibert examines Butler's criticism of the heroic ideals of love and military valour. Part II (Chapters 5 and 6) comprises studies of several elements of Butler's literary method in Hudibras. Chapter 5 analyzes Butler's use of metaphor and of dramatic argument as satirical techniques. Chapter 6 treats the mock-speeches (III,ii) and the burlesque heroical epistles, as well as the narrative method of Hudibras, and the device of the comic narrator. Part III consists of three appendices. Appendix A deals with the question of the identity of the 'West Country knight' upon whom Butler says that he based the character of Hudibras. The evidence in favour of Sir Samuel Luke and Sir Hanry Rosewell is examined and Sir Samuel Rolle is presented as the most likely 'original' of Hudibras A certain amount of evidence in his favour is given for the first time in this appendix. Appendix B criticizes the identification of Ralpho in the 'Key to Hudibras' (1715), presenting for the first time the source from which the author of the 'Key' drew the portrait of 'Isaac Robinson,' the man upon whom (he claims) Butler based his characterization of Ralpho. Appendix C criticizes the attribution to Butler (currently accepted) of Mercurius Menippeus, a political pamphlet first published in 1680 and containing a passage of invective against Sir Samuel Luke. It is argued that the attribution is virtually without foundation

Physical Therapy Management of Scoliosis Resulting in Bilateral Shoulder Pain in an Older Factory Worker: A Case Report

Background: Adolescent Idiopathic Scoliosis (AIS) affects as many as 4 in 100 adolescents. The efficacy of conservative treatments has been closely examined in younger age groups, but little research exists examining conservative management of AIS as adolescents age into adulthood and beyond. Considering the aging population, including those with conservatively managed AIS, is at risk for pain and dysfunction resulting from degenerative changes of spinal alignment, a need for this research exists in order to properly manage cases of peripheral joint dysfunction rooted in spinal deformity. Case Description: A 61 year old male presenting with bilateral shoulder pain also has a history of AIS. Through adolescence, his AIS was managed by observation only and he encountered few issues. His shoulders began hurting more frequently with age until he sought medical attention. This patient was working full time as a factory worker throughout this episode of care. Intervention: Physical therapy to treat shoulder impingement including manual therapy, neuromuscular re-education, therapeutic exercise, and therapeutic activity. Intervention evolved from targeting shoulder pain to increasing spinal mobility and postural control as symptoms improved. Outcome: Improvement of 29.5% as measured by QuickDASH. Patient expressed satisfaction with his recovery and opted to discontinue therapy. Discussion: AIS can continue to alter function and cause pain into adulthood. These symptoms can be treated with physical therapy by implementing interventions targeted at both the spine and the primary symptom location

Food Security in Developing Countries

This paper provides a systematic definition of food security, focusing on its different dimensions; examines the nature and magnitude of the different dimensions of food insecurity in developing countries; discusses the difficult tradeoffs that policy makers face in trying to address food security’s multiple dimensions simultaneously; and explores promising new approaches to address food insecurity. The geographic focus is on Sub-Saharan Africa and South Asia, where the majority of the world’s food insecure people live.food security, hunger, poverty, food policy, economic development, Agricultural and Food Policy, Food Security and Poverty, International Development, O13, O19, Q18,

An application of a generalized management information system to energy policy and decision making : the user's view

This paper presents an approach to the development and use of management information systems that is particularly applicable to systems with the following characteristics: - several classes of users, each of which has a different degree of sophistication - complex and changing security requirements - data exhibits complex and changing inter-relationships - changing needs to be met by information system - must be built quickly nd inexpensively - complex data validation requirements The approach is hierarchical from the user's view in that he may access the system at distinct levels, corresponding to his degree of computer sophistication. A casual user has high level primitives to work with, while an experienced user has more flexible but more detailed low- level primitives. We also have advocated that such systems be implemented in a hierarchical fashion, because this technique provides for ease of debugging, independence of hardware, and a basis for investigating properties of completeness, integrity, correctness, and performance
