A Binary Tree Decomposition Space Of Permutation Statistics, Don Rawlings Jan 1992

A Binary Tree Decomposition Space Of Permutation Statistics, Don Rawlings

Mathematics

Based on the binary tree decomposition of a permutation, a natural vector space of permutation statistics is defined. Besides containing many well known permutation statistics, this space provides the general context for an archetypal recurrence relationship that contains most of the classic combinatorial sequences and some of their known generalizations.

Riemannian Geometry Of Orbifolds, Joseph Ernest Borzellino Jan 1992

Riemannian Geometry Of Orbifolds, Joseph Ernest Borzellino

Mathematics

We investigate generalizations of many theorems of Riemannian geometry to Riemannian orbifolds. Basic definitions and many examples are given. It is shown that Riemannian orbifolds inherit a natural stratified length space structure. A version of Toponogov's triangle comparison theorem for Riemannian orbifolds is proven. A structure theorem for minimizing curves shows that such curves cannot pass through the singular set. A generalization of the Bishop relative volume comparison theorem is presented. The maximal diameter theorem of Cheng is generalized. A finiteness result and convergence result is proven for good Riemannian orbifolds, and the existence of a closed geodesic is shown …

One-Sided Refinements Of The Strong Law Of Large Numbers And The Glivenko-Cantelli Theorem, David Gilat, Theodore P. Hill Jan 1992

One-Sided Refinements Of The Strong Law Of Large Numbers And The Glivenko-Cantelli Theorem, David Gilat, Theodore P. Hill

Research Scholars in Residence

A one-sided refinement of the strong law of large numbers is found for which the partial weighted sums not only converge almost surely to the expected value, but also the convergence is such that eventually the partial sums all exceed the expected value. The new weights are distribution-free, depending only on the relative ranks of the observations. A similar refinement of the Glivenko-Cantelli theorem is obtained, in which a new empirical distribution function not only has the usual uniformly almost-sure convergence property of the classical empirical distribution function, but also has the property that all its quantiles converge almost surely. …

Pleistocene Terrestrial Vertebrates From Near Point San Luis, And Other Localities In San Luis Obispo County, California, George T. Jefferson, Harry L. Fierstine, John R. Wesling, Teh-Lung Ku Jan 1992

Pleistocene Terrestrial Vertebrates From Near Point San Luis, And Other Localities In San Luis Obispo County, California, George T. Jefferson, Harry L. Fierstine, John R. Wesling, Teh-Lung Ku

Biological Sciences

Terrestrial vertebrate remains were recovered from sediments that lie on remnants of the lowest marine wave-cut platform between Point Buchon and Point San Luis. Uranium series ages of these samples, which range from 83 to about 49 ka suggest a correlation to late Pleistocene climatic and eustatic events associated with marine oxygen isotope substage 5a, and establish a maximum age of ≈80 ka for the occurrence of terrestrial mammal fossils. The Point San Luis area assemblage appears typical of the late Pleistocene regional vertebrate paleofauna fauna from west-central California. Five mammalian taxa are added to the Pleistocene record from San …

Enterprise Projects: Experiential Learning In Applied Entomology, Mark D. Shelton Jan 1992

Enterprise Projects: Experiential Learning In Applied Entomology, Mark D. Shelton

Office of the Dean (CAFES) Scholarship

During 1924, when jobs for college students were difficult to find in San Luis Obispo, Calif., a group of entrepreneurial students at the California Polytechnic School negotiated an $80 bank loan from a local lender to raise chickens. Parents and college faculty cosigned the loan, and thus was born the Agricultural Enterprise Program.

Broad-Crested Weir Application On 15,000-Acre Farm, Stuart W. Styles Jan 1992

Broad-Crested Weir Application On 15,000-Acre Farm, Stuart W. Styles

BioResource and Agricultural Engineering

Growers in California have been subjected to increasing pressure to account for water used on the farm due to limited water supplies and increasing energy costs. Water measurement capability provides for equitable distribution of assigned costs and enables effective water management to be accomplished. Broad-crested weirs are proven water measurement devices, especially when applied to on-farm applications. The broad-crested weirs and published data were developed by the USDA Agricultural Research Service in Phoenix, Arizona. This paper is a discussion of an application of these weirs.

Strategies For Effective Risk Communication Under Sara Title Iii: Perspectives From Research And Practice, Richard C. Rich, W. David Conn, William L. Owens Jan 1992

Strategies For Effective Risk Communication Under Sara Title Iii: Perspectives From Research And Practice, Richard C. Rich, W. David Conn, William L. Owens

City and Regional Planning

Title III of the Superfund Amendments and Reauthorization Act of 1986 requires that planning and emergency response agencies be able to communicate with the public in nonemergency situations in order to help citizens understand the risks they face from hazardous materials and to secure citizen participation in designing responses to chemical emergencies. Both research and reports from the field indicate that, with notable exceptions, most Local Emergency Planning Committees created for this purpose are making little or no effort at proactive communication. As a result, citizens are not being educated effectively about the hazards they face and are not acting …

On Capacity Modeling For Production Planning With Alternative Machine Types, Robert C. Leachman, Tali F. Carmon Jan 1992

On Capacity Modeling For Production Planning With Alternative Machine Types, Robert C. Leachman, Tali F. Carmon

Industrial and Manufacturing Engineering

Analyzing the capacity of production facilities in which manufacturing operations may be performed by alternative machine types presents a seemingly complicated task. In typical enterprise-level production planning models, capacity limitations of alternative machine types are approximated in terms of some single artificial capacitated resource. In this paper we propose procedures for generating compact models that accurately characterize capacity limitations of alternative machine types. Assuming that processing times among alternative machine types are identical or proportional across operations they can perform, capacity limitations of the alternative machine types can be precisely expressed using a formulation that is typically not much larger …
