Why Ciao? An overview of the ciao system's design philosophy

Our intention in this note is not to provide a listing of the many features of the Ciao system: this can be found in part for example in the brochures announcing upcoming versions, in the Ciao website, or in more feature-oriented descriptions such as. Instead in this document we would like to describe the objectives and reasoning followed in our design as well as the fundamental characteristics that in our opinion make Ciao quite unique and hopefully really useful to you as a Ciao user.

The theory of electrostatic probes in strong magnetic fields : Thesis submitted to the Faculty of The Graduate School of the University of Colorado for the Degree Doctor of Philosophy Department of Aerospace Engineering Science

A theory is developed of an electrostatic probe in a fully-ionized plasma in the presence of a strong magnetic field. The ratio of electron Larmor radius to probe transverse dimension is assumed to be small. Poisson's equation, together with kinetic equations for ions and electrons are considered. An asymptotic perturbation method of multiple scales is used by considering the characteristic lengths appearing in the problem. The leading behavior of the solution is found. The results obtained appear to apply to weaker fields also, agreeing with the solutions known in the limit of no magnetic field. The range of potentials for wich results are presented is limited. The basic effects produced by the field are a depletion of the plasma near the probe and a non-monotonic potential surrounding the probe. The ion saturation current is not changed but changes appear in both the floating potential Vf and the slope of the current-voltage diagram at Vf. The transition region extends beyond the space potential Vs,at wich point the current is largely reduced. The diagram does not have an exponential form in this region as commonly assumed. There exists saturation in electron collection. The extent to which the plasma is disturbed is determined. A cylindrical probe has no solution because of a logarithmic singularity at infinity. Extensions of the theory are considered.

Pipe3D, a pipeline to analyse integral Field Spectroscopy data: I. New fitting philosophy of FIT3D

We present an improved version of FIT3D, a fitting tool for the analysis of the spectroscopic properties of the stellar populations and the ionized gas derived from moderate resolution spectra of galaxies. This tool was developed to analyze integral field spectroscopy data and it is the basis of PIPE3D, a pipeline used in the analysis of CALIFA, MaNGA, and SAMI data. We describe the philosophy and each step of the fitting procedure. We present an extensive set of simulations in order to estimate the precision and accuracy of the derived parameters for the stellar populations and the ionized gas. We report on the results of those simulations. Finally, we compare the results of the analysis using FIT3D with those provided by other widely used packages, and we find that the parameters derived by FIT3D are fully compatible with those derived using these other tools.

Islamic Political Thought: Reviving a Rationalist Tradition

This work develops the foundations of an Islamic argument for secular, liberal democracy from within the Islamic discursive tradition. First, it challenges the presentation of contemporary Islamic political thought as a unified, continuous development of the classical canon by showing the influence of the now marginalized medieval rationalists in the development of Islamic political thought. The classical rationalist concern with divine justice forced the founders of Sunni orthodoxy to state their epistemologies and their positions on ethical ontology. The orthodox positions, and their related methods of legal-juristic reasoning, are shown to be incapable of accommodating the modern Islamic positions on political representation, slavery, and just war. This leads to the second argument of the work, that the modern Islamic discourse is better understood as a reflection of the central concern with justice and its rationalist epistemology and ethical ontology we find in the writings of classical rationalists. This argument is made by examining the works of three classical rationalists, a theologian, a philosopher, and a historian. Their political positions, shaped by their rationalism and concern with justice, challenged their orthodox contemporaries, and provide substantive critiques of the classical political accommodations, methods of politico-legal reasoning, and hence, of modern Islamist political projects. The final chapter reveals how far the mainstream of Islamic political thought has deviated from the classical discourses, since the 19th century, by adopting the language and ideals of the European Enlightenment. This shift is presented as a triumph of classical rationalism over literalism, whose epistemological foundations and ontological implications have yet to be acknowledged and appreciated.

The African-American Islamic Renaissance and the Rise of the Nation of Islam

This dissertation examines African-American Islamic culture from 1920 through 1959, a period I label the "African-American Islamic Renaissance" (AAIR). The AAIR is characterized by a significant increase in interest in Islam, extreme diversity in views about Islam, and the absence of a single organization dominating African-American Islamic culture for a significant amount of time. Previous works dealing with African-American Islam in this period have failed to fully recognize these features, particularly the last of these. As a result, explanations for the rise of the Nation of Islam (NOI) have not satisfactorily explained why it was only the NOI--and not other Islamic groups that were more popular than the NOI up until the mid-1950s--that became a "mass movement," gaining the allegiance of tens of thousands of African Americans. There has been some tendency, for instance, to assume that the NOI was the most popular African-American Islamic group by the early 1950s, a notion that is probably an inference drawn from two other popular but inaccurate assumptions: that the NOI's rise was due primarily to its radical racialized doctrines and its charismatic leaders, particularly Malcolm X, who became a popular minister for the group in the early 1950s. I argue, however, that the NOI was in fact not the most popular African-American Islamic group until at least 1955, and even as late as 1959 its official membership numbers were not particularly large by AAIR standards. Also, its doctrines were not especially unique in the AAIR, nor was its having extremely charismatic leaders. I contend that the success of the NOI in the mid-to-late 1950s was the result of three levels of changes at the time: internal, external in the AAIR community, and external in the broader U.S, culture.

[Natural Philosophy book list, 1790]

One leaf containing a handwritten list of books marked "Natural Philosophy." Entries contain the author's last name and abbreviated title; five books have dates. The page is inscribed "Callender" and likely refers to John Callender (Harvard AB 1790).

One leaf containing a handwritten list of books with one column marked "Ethics" and the other column marked "Moral Philosophy." Entries contain the author's last name and abbreviated title. The page is inscribed "Vose," likely referring to Roger Vose (Harvard AB 1790), and the verso has a fragment of a poem.

[Ethics and moral philosophy book list, 1790]

One leaf containing a handwritten list of books generally on ethics and moral philosophy, though no subject is identified. Entries contain the author's last name and abbreviated title. The page is inscribed "Paine," likely referring to Robert Treat Paine (Harvard AB 1792), and the verso has a fragment of a student essay on the theme "An undevout astronomer is mad," signed "Paine."

Rules and orders relating to a Professor of the Mathematicks, of Natural and Experimental Philosophy, in Harvard College, 18 January 1726

This folder contains a single document describing the "rules and orders" of the Hollis Professor of Mathematics and Natural Philosophy. The document begins by defining the subjects to be taught by the Hollis Professor including natural and experimental philosophy, elements of geometry, and the principles of astronomy and geography. It then outlines the number of public and private lectures to be given to students, how much extra time the professor should spend with students reviewing any difficulties they may encounter understanding class subject matter discussed, and stipulates that the professor's duties shall be restricted solely to his teaching activities and not involve him in any religious activities at the College or oblige him to teach any additional studies other than those specified for the Hollis Professor of Mathematics and Natural Philosophy. Furthermore, the rules establish the professor's salary at £80 per year and allow the professor to receive from students, except those students studying theology under the Hollis Professor of Divinity, an additional fee as determined by the Corporation and Board of Overseers, to supplement his income. Moreover, the rules assert that all professorship candidates selected by the Harvard Corporation must be approved by Thomas Hollis during his lifetime or by his executor after his death. Finally, the rules state that the Hollis professor take an oath to the civil government and declare himself a member of the Protestant reformed religion. This document is signed by Thomas Hollis and four witnesses, John Hollis, Joshua Hollis, Richard Solly, and John Williams.
