Abstract Although a statewide trip table is an important ingredient in the statewide planning process, such information is difiScult to obtain. The study described in this report investigated the appUcabihty to the state-level problem of existing software developed to estimate trip tables in urban areas (or smaller) from link counts. Criteria that would form the basis for determining the apphcabihty of any particular software package were developed. Packages such as The Highway Emulator (THE), PC- LINKOD, and Fast Matiix CaUbration (FMC) were tested using small and medium sized networks. Because FMC performed the best on these tests, it was applied to the state-level hip table estimation problem. However, FMC was designed to update an existing trip table, and Indiana had no such previous trip table. As a result, an "0-D Factoring" procedure was adopted to convert zone-by-zone origin and destination totals into an initial hip table that could be updated by FMC. By making some adjustments to the elasticities in FMC, a trip table was developed for the Indiana state highway network. 17. Keywords 18.

  • T-AFMD-89-1 Failed Financial Institutions: Reasons, Costs, Remedies, and Unresolved Issues
    United States General Accounting Office Testimony For Release on FAILED FINANCIAL INSTITUTIONS: Delivery Reasons, Costs, Remedies and Unresolved Issues Expected at 9:00 a.m. PST Friday January 13, 1989 Statement of Frederick D. Wolf, Director Accounting and Financial Management Division Before the Committee on Banking, Finance and Urban Affairs House of Representatives c!44-.J.: r 1 / ;77& GAO/T-AFMD-89-l GAOPmrl62(12/27) Mr. Chairman and Members of the Committee: We are pleased to appear today to discuss preliminary observations from ongoing work assessing characteristics and management practices of financial institutions which have failed in recent years. We will also discuss preliminary issues related to the Bank Board's recent resolution actions and will offer thoughts on (1) the kinds of actions the Congress should consider in its efforts to resolve the financial problems of the thrift industry and its insurer, the Federal Savings and Loan Insurance Corporation (FSLIC), and (2) actions needed to prevent this situation from recurring. FINANCIAL INSTITUTIONS FAILING AT RECORDRATES We are currently faced with a crisis of major proportions. Not since the early 1930s have financial institutions failed in such unprecedented numbers. In 1987, 203 commercial banks were closed or assisted at an estimated $3 billion net cost to the Federal Deposit Insurance Corporation (FDIC). In 1988, the number of banks closed or assisted rose to 221. As a result, FDIC expects to incur a loss of $3 billion to $4 billion to its deposit insurance fund. However, with this loss, the fund will have a balance of about $14 billion to $15 billion, and FDIC expects that balance to increase slightly or remain stable this year.

  • Passive and Active Drag of Paralympic Swimmers
    PASSIVE AND ACTIVE DRAG OF PARALYMPIC SWIMMERS By Yim – Taek OH A thesis submitted in partial fulfilment of the requirement of the Manchester Metropolitan University for the degree of Doctor of Philosophy Institute for Performance Research Department of Exercise and Sport Science Manchester Metropolitan University SEPTEMBER 2015 i ACKNOWLEDGEMENTS Above all, I give thanks to my Lord Jesus Christ with my whole heart, who planned, carried and finished my PhD. I dedicate this thesis to my precious Lord Jesus Christ. I would like to give thanks to God, as He allows me to see my world-best supervisor Dr Carl Payton. I would like to express my sincere gratitude to him for his invaluable help and inestimable encouragement throughout my PhD. Through his leadership this thesis could consolidate its position as a potential contributor to future IPC classification. I would also like to offer my thanks to Dr Conor Osborough who offered me worthy help, especially during the ‘Passive drag project’ at the London 2012 Paralympic games. I would like to give my thanks to Dr Casey Lee and Dr Danielle Formosa who, as the team members of the project, helped me in collecting the data. I must also thank Prof Brendan Burkett of the University of Sunshine Coast and all the members of the IPC Sports Science Committee. With the support of IPC Sports Science this thesis was able to conduct experiments during both the London 2012 Paralympic games and the Montreal 2013 IPC Swimming World Championships. Additional thanks goes to Mr Des Richards and Mr Grant Rockley who helped me in preparing the experimental devices and Mr Eric Denyer who kindly helped in the proofreading of the thesis.

  • BUILDINGS and THEIR APPLICATIONS in GEOMETRY and TOPOLOGY to the Memory of Professor S.S. Chern Contents 1 Introduction and Hist
    ASIAN J. MATH. c 2006 International Press Vol. 10, No. 1, pp. 011–080, March 2006 002 BUILDINGS AND THEIR APPLICATIONS IN GEOMETRY AND TOPOLOGY∗ LIZHEN JI† To the memory of Professor S.S. Chern Abstract. Buildings were first introduced by J. Tits in 1950s to give systematic geometric inter- pretations of exceptional Lie groups and have been generalized in various ways: Euclidean buildings (Bruhat-Tits buildings), topological buildings, R-buildings, in particular R-trees. They are useful for many different applications in various subjects: algebraic groups, finite groups, finite geometry, representation theory over local fields, algebraic geometry, Arakelov intersection for arithmetic va- rieties, algebraic K-theories, combinatorial group theory, global geometry and algebraic topology, in particular cohomology groups, of arithmetic groups and S-arithmetic groups, rigidity of cofinite subgroups of semisimple Lie groups and nonpositively curved manifolds, classification of isoparamet- ric submanifolds in Rn of high codimension, existence of hyperbolic structures on three dimensional manifolds in Thurston’s geometrization program. In this paper, we survey several applications of buildings in differential geometry and geometric topology. There are four underlying themes in these applications: 1. Buildings often describe the geometry at infinity of symmetric spaces and locally symmetric spaces and also appear as limiting objects under degeneration or scaling of metrics. 2. Euclidean buildings are analogues of symmetric spaces for semisimple groups defined over local fields and their discrete subgroups. 3. Buildings of higher rank are rigid and hence objects which contain or induce higher rank buildings tend to be rigid. 4. Additional structures on buildings, for example, topological buildings, are important in applications for infinite groups.
