Stranger Citizens: Migrant Influence and National Power in the Early American Republic

John McNelis O’Keefe

Stranger Citizens examines how foreign migrants who resided in the United States gave shape to citizenship in the decades after American independence in 1783. During this formative time, lawmakers attempted to shape citizenship and the place of immigrants in the new nation, while granting the national government new powers such as deportation.

John McNelis O'Keefe argues that despite the challenges of public and official hostility that they faced in the late 1700s and early 1800s, migrant groups worked through lobbying, engagement with government officials, and public protest to create forms of citizenship that worked for them. This push was made not only by white men immigrating from Europe; immigrants of color were able to secure footholds of rights and citizenship, while migrant women asserted legal independence, challenging traditional notions of women's subordination.

Stranger Citizens emphasizes the making of citizenship from the perspectives of migrants themselves, and demonstrates the rich varieties and understandings of citizenship and personhood exercised by foreign migrants and refugees. O'Keefe boldly reverses the top-down model wherein citizenship was constructed only by political leaders and the courts.
Engineering Thermodynamics - A Graphical Approach

Israel Urieli

This open educational resource is intended to be a totally self-contained learning resource in Engineering Thermodynamics. It is designed to be suitable for a two course sequence for Mechanical Engineering majors. It may, however, be used in any format and for any purpose, including self-study. The various unique pedagogical features of this web resource are discussed in Paper AC 2010-47 (see additional files below), presented at the 2010 ASEE Annual Conference (refer also to the OU Video).

There is normally a printed Thermodynamics Properties Tables booklet which accompanies the web resource. If this is unavailable then this booklet can be downloaded and printed (see additional files below).

In Part 1 we introduce the First and Second Laws of Thermodynamics. Rather than applying these laws in terms of components and processes we have chosen a more interesting approach of applying them to complete cycles or systems. The ideal Stirling cycle machine is developed as a prime example of both Laws (refer to a paper: A Meeting between Robert Stirling and Sadi Carnot in 1824 (see additional files below) presented at the 2014 ISEC), and complete ideal heat engines, steam power plants and refrigeration systems are evaluated in Chapters 3 and 4. Where appropriate, we introduce graphical two-dimensional plots to evaluate the performance of these systems rather than relying on equations and tables. This enables intuitive visualization of the solutions to a high degree of accuracy. The section on Carbon Dioxide as a refrigerant does not appear in any textbook that I am aware of. Because of the Global Warming crisis, the currently used refrigerant, R134a, will be banned from usage in automobile air conditioning systems in Europe within a few years. Among the alternatives being developed we prefer to return to Carbon Dioxide as the refrigerant of choice.

Stirling Cycle Machine Analysis

Israel Urieli

Dedicated to William T. Beale (1928 - 2016), inventor of the Free Piston Stirling Engine, Mentor and Frien.

This web resource is intended to be totally self contained learning resource for the analysis and development of computer simulation of single phase, piston/cylinder Stirling cycle machines. It includes thermodynamic, heat transfer and fluid flow friction analysis, and until 2012 it was used as resource material for an advanced course for Mechanical Engineering majors. The course structure was based on the book by I.Urieli & D.M.Berchowitz 'Stirling Cycle Engine Analysis' (Adam Hilger, 1984). The computer simulation program modules (originally written in FORTRAN) have all been updated and rewritten in MATLAB, a convenient interactive language which allows direct graphical output - essential for Stirling cycle analysis. A complete set of all the m-files are developed and provided, and they can be augmented and adapted as needed for specific engine/refrigerator configurations.

Chapter 1: Background and Introduction

Chapter 2: Basic Engine Configurations

Chapter 3: Ideal Isothermal Analysis

We define and analyze the Ideal Isothermal model of a Stirling engine, including the Schmidt Analysis, and discuss its limitations. One obviously incorrect conclusion of this analysis is that all three heat exchangers are redundant, and only contribute dead space, since all required heat transfer processes occur in the isothermal compression and expansion spaces. Nevertheless we can obtain a better understanding of a specific design, particularly when we augment the solution with Allan Organ's particle mass flow analysis.

Chapter 4: Ideal Adiabatic Analysis

We find that the Ideal Isothermal analysis predicts that the heat exchangers of a Stirling engine are redundant, thus we cannot seriously use this model to predict the ideal performance of an actual machine. We thus turn to an alternative model in which the compression and expansion spaces are adiabatic. We find that there is no closed form solution to this model and we have to resort to computer simulation. We gain various insights from using this model in particular with regards to the importance of the regenerator, which was not understood for a significant period.

Chapter 5: Simple Analysis

This analysis approach uses the Ideal Adiabatic model as a basis to predict the real performance of the three heat exchanger sections, particularly with regards to heat transfer and pressure drop. The name Simple Analysis is to indicate that this is a simplification of the actual non-steady flow heat exchange, however it enables a parametric analysis of a specific machine.

This learning resource includes a set of tutorial MATLAB computer program modules for simulating specific Stirling engine configurations. The complete set of m-files can be downloaded in compressed format sea.zip (sea = stirling engine analysis). These modules can be augmented and adapted as required to simulate a specific engine design. Currently the engine modules are for Alpha machines, including a Sinusoidal drive, a Ross Yoke-drive and a Ross Rocker-V engine. The heat exchanger types include tubular, annular gap, and slot heat exchangers, and the regenerator matrix types include screen mesh and rolled foil matrices. Working gas types include air, helium, and hydrogen.

Note that the purpose of this learning resource is to develop an appreciation and understanding of the complexity of practical Stirling cycle machine performance simulation, mainly due to the heat transfer processes. It is not intended as an alternative to the Sage Software for engineering modeling and optimization of Stirling cycle machines.
