Minimal TCP/IP implementation with proxy support

Over the last years, interest for connecting small devices such as sensors to an existing network infrastructure such as the global Internet has steadily increased. Such devices often has very limited CPU and memory resources and may not be able to run an instance of the TCP/IP protocol suite. In this thesis, techniques for reducing the resource usage in a TCP/IP implementation is presented. A generic mechanism for offloading the TCP/IP stack in a small device is described. The principle the mechanism is to move much of the resource demanding tasks from the client to an intermediate agent known as a proxy. In particular, this pertains to the buffering needed by TCP. The proxy does not require any modifications to TCP and may be used with any TCP/IP implementation. The proxy works at the transport level and keeps some of the end to end semantics of TCP. Apart from the proxy mechanism, a TCP/IP stack that is small enough in terms of dynamic memory usage and code footprint to be used in a minimal system has been developed. The TCP/IP stack does not require help from a proxy, but may be configured to take advantage of a supporting proxy

The Impact of Latin Culture on Medieval and Early Modern Scottish Writing

In the late medieval and early modern periods, native tongues and traditions, including those of Scotland, cohabited and competed with latinitas in fascinating and inventive ways. Scottish latinity had its distinctive stamp, most intriguingly so in its effects upon the literary vernacular and on themes of national identity. The present book shows how, when viewed through the prism of its latinity, Scottish textuality was distinctive and fecund. The flowering of Scottish writing owed itself to a subtle combination of literary praxis, the ideal of eloquentia, and ideological deftness. This combination enabled writers to service a burgeoning national literary tradition, and to transcend the subject matter of nation through fruitful and energetic treatment of issues of universal appeal.https://scholarworks.wmich.edu/mip_smemc/1001/thumbnail.jp

Eisenhower’s parallel track reassessing President Eisenhower’s activism through an analysis of the development of the first US space policy

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University LondonAbstract: Historians of the early space age have established a norm whereby President Eisenhower's actions are judged solely as a response to the launch of the Sputnik satellite, and are indicative of a passive, negative presidency. His low-key actions are seen merely as a prelude to the US triumph in space in the 1960s. This study presents an alternative view showing that Eisenhower’s space policy was not a reaction to the heavily-propagandised Soviet satellite launches, or even the effect they caused in the US political and military elites, but the continuation of a strategic track. In so doing, it also contributes to the reassessment of the wider Eisenhower presidency. Having assessed the development of three intersecting discourses: Eisenhower as president; the genesis of the US space programme; and developments in Cold War US reconnaissance, this thesis charts Eisenhower’s influence both on the ICBM and reconnaissance programmes and his support for a non-military approach to the International Geophysical Year. These actions provided the basis for his space policy for the remainder of his presidency. The following chapters show that Sputnik had no impact on the policies already in place and highlight Eisenhower’s pragmatic activism in enabling the implementation of these policies by a carefully-chosen group of expert ‘helping hands’. This study delivers a new interpretation of Eisenhower’s actions. It argues that he was operating on a parallel track that started with the Castle H-bomb tests; developed through the CIA's reconnaissance efforts and was distilled in the Aeronautics and Space Act of 1958. This set a policy for US involvement in outer space that matched Eisenhower’s desire for a balanced budget and fundamental belief in maintaining peace. By challenging the orthodox view, this paper shows that President Eisenhower’s space policy actions were strategic steps that provided a logical next step for both civilian and military space programmes at the completion of the International Geophysical Yea

Anticipating the Astronaut: Subject Formation in Early American Space Medicine, 1949-1959

This project expands the scope of existing Space Race histories of the American astronaut mostly focused on daring test-pilots in the 1960sby examining a prior decade of research conducted by doctors and psychologists in the military field of space medicine on a surprising array of non-test-pilot subjects. Examining the historical, social, cultural, and political dimensions of space medicines pre-NASA work, which began in 1949, reveals two key insights. The first is that the astronaut emerged in the immediate aftermath of World War Two and developed in concert with the Cold War for a decade before NASA began operations. The second is that the kind of person space medicine experts came to consider right for space was not solely determined by the requirements of spacecraft control and environmental systems, but also by cultural ideas about bodies, minds, technology, and extreme environments in post-war American society. Based on research conducted at NASA, USAF, and NARA archives, this study examines four nearly-forgotten but revealing episodes in which non-test-pilot subjects were used to establish standards and practices for astronauts later adopted and adapted by NASA. This projects four main chapters each focus on work with a different type of subject: a young, non-flying airmans week-long ordeal playing the role of astronaut in the first Space Cabin Simulator; a mountain-based study of high-altitude Indigenous people for astronaut acclimatization; the post-flight lives of monkeys Able and Baker, Americas first celebrity space animals; and the Lovelace Woman in Space Program, a comparative study of women pilots for space fitness. Beyond the purely technical problem of Who can survive a spaceflight?, this work developing the astronaut posed a more fundamental but unspoken question about Americans: Who should fight the Cold War? Critically examining space medicines work with these non-test-pilot subjects defamiliarizes the astronaut, recasting this utopian hero of the civilian Space Race as an older Cold War military creation with a surprisingly dystopian origin. Moving beyond space-race mythologizing, or internalist scientific progress narratives, this approach challenges the enduring gendered and racialized vision of the white, male, military pilot at its origin in an effort to demilitarize the astronaut and human ventures in space
