Microfog lubricant application system for advanced turbine engine components, phase 2. Tasks 3, 4 and 5: Wettability and heat transfer of microfog jets impinging on a heated rotating disc, and evaluation of reclassifying nozzles and a vortex mist generator

The wettabilities and heat transfer rates of microfog jets (oil-mist nozzle flows) impinging on a heated rotating disc were determined under an inert atmosphere of nitrogen at temperatures ranging from 600 to 800 F. The results are discussed in relation to the various factors involved in the microfog lubricant application systems. Two novel reclassifying nozzles and a vortex mist generator were also studied

Quarterly literature review of the remote sensing of natural resources

The Technology Application Center reviewed abstracted literature sources, and selected document data and data gathering techniques which were performed or obtained remotely from space, aircraft or groundbased stations. All of the documentation was related to remote sensing sensors or the remote sensing of the natural resources. Sensors were primarily those operating within the 10 to the minus 8 power to 1 meter wavelength band. Included are NASA Tech Briefs, ARAC Industrial Applications Reports, U.S. Navy Technical Reports, U.S. Patent reports, and other technical articles and reports

A cybernetic approach to prediction with an outline of an adaptive optical computer

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Since the pioneering work of Kolmogoroff and Wiener the use of computing devices to solve problems concerned with - the prediction of future states of a time series has stimulated a large amount of research. Despite all this, however the results have been disappointing. If significant progress were to be made in this field it would lead not only to the possibility of forecasting economic events, the weather, earthquakes, epidemics, and so on, but also -to the possibility of simulating these system. Approaches involving the programming of a computer to carry out this task run into the difficulty of defining the variables involved in a precise enough manner, whereas using the computer -to investigate all the past events of that time series requires a large processing time and an enormous memory store. This thesis examines an approach to this problem which involves the use of a device for processing information in a parallel manner. The system envisaged consists of a holographic recognition device controlled by a digital computer -a combination of analogue and digital techniques. The principle of this device is that developed by Gabor and others, and allows the system to learn to predict the future of a time series. The system learns to predict the future of a time series by using a past length of time series as a training set. Using this training set it attempts to predict the next values of the time series, which can then be compared with the actual time series. The system, then, attempts to optimize its prediction by minimizing the error between the predicted and actual values

Shuttle synthetic aperture radar implementation study, volume 1

Results of an implementation study for a synthetic aperture radar for the space shuttle orbiter are described. The overall effort was directed toward the determination of the feasibility and usefulness of a multifrequency, multipolarization imaging radar for the shuttle orbiter. The radar is intended for earth resource monitoring as well as oceanographic and marine studies

What Are the Visible and Invisible Archaeologies of Conflict in the Irish Landscape of Donegal and How May These Be Contextualised and Represented Through Arts Practice

The research question - What are the visible and invisible archaeologies of conflict in the Irish landscape of Donegal and how may these be contextualised and represented through arts practice? has been addressed through textual and historical research and through arts practice, using lens-based media in the exploration of an historic series of military circumstances, in the contemporary Irish landscape of County Donegal. The research undertaken and the resulting outcomes are presented as a textual narrative and as visual arts practice. The thesis material is composed of five chapters, each of which discusses selected arguments in the fields of, respectively; the modification of human sight through opticality and the emergence of modern photography, origins of the geographical discipline and the visual influence on formations of cultural landscape, a contemporary archaeological approach to sites of conflict and examples of relevant artwork, and a characterisation and discussion of Ireland\u27s position of neutrality during the Second World War, including a critical review of the images produced on this topic. This fourth chapter is intended to function as context and framework for the fifth chapter, the re-imagining of the landscape through the arts practice, shown in the Arc of Fire website, which is composed of selected visual material from the live research phase and the site-specific exhibition installed in Fort Dunree in the Inishowen peninsula. The conclusions form the final part of the thesis. Photography and lens based processes, explored as a critical history and employed as a working method of my professional arts practice, is fundamental to the research project
