A Generalization Of Levy's Concentration-Variance Inequality, R. D. Foley, Theodore P. Hill, M. C. Spruill Mar 1990

A Generalization Of Levy's Concentration-Variance Inequality, R. D. Foley, Theodore P. Hill, M. C. Spruill

Research Scholars in Residence

Sharp lower bounds are found for the concentration of a probability distribution as a function of the expectation of any given convex symmetric function φ. In the case φ(x)=(x-c)2, where c is the expected value of the distribution, these bounds yield the classical concentration-variance inequality of Lévy. An analogous sharp inequality is obtained in a similar linear search setting, where a sharp lower bound for the concentration is found as a function of the maximum probability swept out from a fixed starting point by a path of given length.

Biomineralization Of Ferrimagnetic Greigite (Fe3s4) And Iron Pyrite (Fes2) In A Magnetotactic Bacterium, Stephen Mann, Nicholas C.H. Sparks, Richard B. Frankel, Dennis A. Bazylinski, Holger W. Jannasch Jan 1990

Biomineralization Of Ferrimagnetic Greigite (Fe3s4) And Iron Pyrite (Fes2) In A Magnetotactic Bacterium, Stephen Mann, Nicholas C.H. Sparks, Richard B. Frankel, Dennis A. Bazylinski, Holger W. Jannasch

Physics

The ability of magnetotactic bacteria to orientate and navigate along geomagnetic field lines is due to the controlled intracellular deposition of the iron oxide mineral, magnetite (Fe3O4)1,2. The function and crystal chemical specificity of this mineral has been considered to be unique amongst the prokaryotes3. Moreover, the bacterial production of magnetite may represent a significant contribution to the natural remanent magnetism of sediments4,5. Here we report, the intracellular biomineralization of single crystals of the ferrimagnetic iron sulphide, greigite (Fe3S4), in a multicellular magnetotactic bacterium common in …

Ultrasonic Measurement Of The Geometric Parameters Of Gaseous Voids In Low Gravity Fluid Containers, A. T. Patten, William W. Durgin Jan 1990

Ultrasonic Measurement Of The Geometric Parameters Of Gaseous Voids In Low Gravity Fluid Containers, A. T. Patten, William W. Durgin

Office of the Provost Scholarship

A demonstration system for the ultrasonic gauging of fluids in low-gravity has been designed and tested. For purposes of simplification, it was assumed that vapor within a liquid container in low-gravity would form a spherical bubble which would float freely in the container. The project was designed to show that ultrasonic techniques could be used to determine the geometry of the resulting sphere given a worst-case transducer arrangement. The motivation was to simplify transducer mounting requirements so that propellant or other storage vessels could be fitted with ultrasonic gauging systems with a single or perhaps a few transducer penetrations. Data …

1990 El Rodeo, California Polytechnic State University - San Luis Obispo

El Rodeo Yearbook

El Rodeo, the Cal Poly yearbook, was published annually by the Associated Students. Many of the volumes featured a theme. The collection contains volumes from 1927 to 1980. Publication was suspended between 1943-1945 (during World War II) and between 1972-1976. El Rodeo was published one last time in 1990.


Iron Compounds In Brazilian Pre-Columbian Pigments Identified By 57Fe Mossbauer Spectroscopy And X-Ray Powder Diffraction, F. F.T. De Araujo, M. A.B. De Araujo, R. B. Frankel, G. C. Papaefthymiou, V. W. Vieira Jan 1990

Iron Compounds In Brazilian Pre-Columbian Pigments Identified By 57Fe Mossbauer Spectroscopy And X-Ray Powder Diffraction, F. F.T. De Araujo, M. A.B. De Araujo, R. B. Frankel, G. C. Papaefthymiou, V. W. Vieira

Physics

Mossbauer spectroscopy and X-ray powder diffraction have been used to identify iron compounds in pre-Columbian pigments, probably used for art decorating, collected from the oldest archaeological site of Early Man presently known in American at Sao Raimundo Nonato, in Northeastern Brazil. The iron compounds were identified as being alpha-Fe203 (haematite) with full Morin transition supressed and small particles of alpha-FeOOH (goethite).

Multicolored Simon Newcomb Problems, Don Rawlings Jan 1990

Multicolored Simon Newcomb Problems, Don Rawlings

Mathematics

Recent progress made by Desarmenien and Foata in the area of permutation statistics indirectly points out a certain gap in the theory of sequence enumeration. The remedy of the situation lies in the consideration of some colorful extensions of the Simon Newcomb problem.
