Design, Simulation, And Fabrication Of A Flow Sensor For An Implantable Micropump, Matthew J. Waldron

Theses

The design, simulation, and fabrication of a flow sensor to be integrated into an implantable micropump is presented. The flow sensor operates by the method of thermal anemometry, in which heat is dissipated from a resistive element held in the flow of the fluid. The rate at which heat is carried away is dependent on the flow rate and is directly related to the thermal conductance. A control circuit utilizing the constant-temperature anemometry mode of operation is used to generate a change in voltage in response to change in thermal conductance, and subsequently, flow rate. A mathematical expression describing the …

The Cartography Of National Humiliation And The Emergence Of China’S Geobody, William A. Callahan

Research Collection School of Social Sciences

Maps are an important site of the production and consumption of the national image. This essay examines modern Chinese maps to show how the very material borders between foreign and domestic space are the outgrowth of the symbolic workings of historical geography and the conventions of Chinese cartography. These maps do much more than celebrate the extent of Chinese sovereignty; they also mourn the loss of national territories through a cartography of national humiliation. The goal of this essay is to shift our attention from the diplomatic issues of international borders to examine what Chinese maps of China can tell …

All The Beef To The Heels Were In: Advertising And Plenty In Joyce's Ulysses, Mindy Jo Ratcliff

College of Graduate Studies: Theses & Dissertations

Privileging a historicist approach, this document explores the presence of consumer culture, particularly advertising, in James Joyce's seminal modernist novel, Ulysses (1922). It interrogates Joyce's awareness of how a broad upswing in Ireland's post-Famine economy precipitated advertising-intensive consumerism in both rural and urban Ireland. Foci include the late-nineteenth century transition in agriculture from arable farming to cattle-growing (grazier pastoralism), which, spurring economic growth, facilitated the emergence of a strong farmer rural bourgeoisie. The thesis considers how Ulysses inscribes and critiques that relatively affluent coterie's expenditures on domestic cultural tourism, as well as hygiene-related products, whose presence on the Irish scene …

A Modified Bisected-T Matching Network For Microwave Filter Design, Azad Raheem

Iraqi Journal of Computers, Communications, Control and Systems Engineering

In this paper, a proposed method to implement the image parameter filters is presented. It is based on cascading π-networks and using a proposed bisected-T m-derived matching section to the source and load impedances instead of the use of the cascaded T-networks and the classical bisected-π matching sections. The proposed method achieves the advantage of reducing the total number of the inductors in the circuit which is a great benefit for circuit implementation in the recent monolithic microwave integrated circuit (MMIC) technology. The method also finds application in broadband microwave distributed amplifiers design.

Relative Performance Comparison And Loss Estimation Of Seismically Isolated And Fixed-Based Buildings Using Pbee Approach, Prayag J. Sayani

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Current design codes generally use an equivalent linear approach for preliminary design of a seismic isolation system. The equivalent linear approach is based on effective parameters, rather than physical parameters of the system, and may not accurately account for the nonlinearity of the isolation system. The second chapter evaluates an alternative normalized strength characterization against the equivalent linear characterization. Following considerations for evaluation are included: (1) ability to effectively account for variations in ground motion intensity, (2) ability to effectively describe the energy dissipation capacity of the isolation system, and (3) conducive to developing design equations that can be implemented …

Native Earth Electric Field Measurements Using Small Spacecraft In Low Earth Orbit, John A. Pratt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The use of small satellites to measure the native electric field of the earth has historically presented many problems as a result of the generally modest pointing capabilities of small satellites. In spite of this, the cost of small satellites makes them ideal for just such scientific missions. This thesis details many of the constraints of electric field measuring missions as well as the requirements on any spacecraft designed to accomplish such. The data from a small sounding rocket mission is then analyzed and its usefulness discussed. Possible other methods for use are also discussed.
