Second Note on Basic Interval Arithmetic for IEEE754R
No full textThe IFIP Working Group 2.5 on Numerical Software (IFIPWG2.5) wrote on 5th Septem-
ber 2007 to the IEEE Standards Committee concerned with revising the IEEE Floating-
Point Arithmetic Standards 754 and 854 (IEEE754R), expressing the unanimous
request of IFIPWG2.5 that the following requirement be included in the future computer
arithmetic standard:
For the data format double precision, interval arithmetic should be made
available at the speed of simple floating-point arithmetic.
IEEE754R (we believe) welcomed this development. They had before them a document
defining interval arithmetic operations but, to be the basis of a standards document, it
needed more detail. Members of the Interval Subroutine Library (ISL) team were asked
to comment, in an email from Ulrich Kulisch that enclosed one from Jim Demmel to Van
Snyder raising the issue. This paper provides ISL's comments

Hybrid Interval Marching / Branch and Bound Method for Parametrized Nonlinear Systems
No full textAbstract. The hybrid interval marching / branch and bound method for parametrized nonlinear systems presented in this paper can find all the solution components (curves) with mathematical certainty within a given search region of n-space. Kearfott and Xing introduced an interval step control method which improved on floating point step controls with a mathematical guarantee that the predictor algorithm will not jump from one path to another. But those methods did not try to detect all the solution components (curves) in a search region, and also their algorithms depend on heuristics to adjust box sizes. The algorithms for our hybrid interval marching / branch and bound method for parametrized nonlinear systems not only can find all global solution components of n-dimensional parametric curves but also depend on the geometry of a function rather than heuristics to set the box size. Snyder’s implicit curve algorithm, which employs subdivision and global parameterizabability, can find the global solution curves of nonlinear parametric equations, but his method was just 2-dimensional. Our algorithm is designed to handle n-dimensional systems of nonlinear parametric equations. We successfully ran our hybrid interval marching / branch and bound method for several test functions
Royal Religious Authority: Morocco’s "Commander of the Faithful"
No full textKing Mohammed VI of Morocco has cultivated the country’s image as a bastion of moderate Islam and of himself as a strategic partner, but to what extent does his international reputation correspond to public opinion in Morocco? In this paper, the author evaluates the domestic standing of the king and other religious figures as part of a larger Baker Institute study (https://www.bakerinstitute.org/research/new-guardians-religion-islam-and-authority-middle-east/) on religious authority in the Middle East

No full textArticle written by Thomas R. Bodine about Japanese American incarceration, incarceration camps, and race and racism.The Bishop James Chamberlain Baker Collection includes letters, documents, and articles about Japanese Americans during World War II. Subjects in the collection include Japanese Americans mass removal, Pearl Harbor and the aftermath, religion, and support from the non-Japanese American community. The collection was digitized and made accessible online by CSUDH Gerth Archives and Special Collections
Interval Computations on the Spreadsheet
No full textThis paper reviews work on using interval arithmetic as the basis for next generation spreadsheet programs capable of dealing with rounding errors, imprecise data, and numerical constraints. A series of ever more versatile computational models for spreadsheets are presented beginning with classical interval arithmetic and ending with interval constraint satisfaction. In order to demonstrate the ideas, an actual implementation of each model as a class library is presented and its integration with a commercial spreadsheet program is explained
Georgian projections of French Revolutionary madness

Abstract generalized bisection and a cost bound

; this framework contains a new idea for handling the occurrence of roots on boundaries. We then present and prove a bound on the total amount of computation which is valid for any algorithm in the class. Finally, we define a specific prototypical algorithm valid for F satisfying certain natural smoothness properties; we show that it satisfies the hypotheses for the general framework. This algorithm is based on "bisection" of generalized rectangles, the Kantorovich theorem, and second-order Taylor type models for F. It is meant to provide further guidelines for the development of effective heuristics, etc., for actual implementations.</p
