A Technique For Analyzing Radiation From Conformal Antennas Mounted On Arbitrarily-Shaped Conducting Bodies, Dean Arakaki, Douglas H. Werner, Raj Mittra

Electrical Engineering

This paper presents an efficient method to solve the problem of radiation from conformal aperture and microstrip antennas mounted on arbitrarily shaped conducting bodies. The method, based on the surface equivalence and reciprocity principles, uses a combination of the finite difference time domain (FDTD) and method of moments (MoM) techniques to substantially improve the computational efficiency of the radiation pattern calculation. When the geometry and location of the radiating element are modified, only a small portion of the overall analysis requires re-simulation. This leads to a significant improvement in computational efficiency over presently used techniques, and can substantially improve the …

Molecular Aspect Of Leaf Senescence, Edward Himelblau, Betania Quirino, Yoo-Sun Noh, Richard Amasino

Biological Sciences

Senescence is the last stage of leaf development and one type of programmed cell death that occurs in plants. The relationships among senescence programs that are induced by a variety of factors have been addressed at a molecular level in recent studies. Furthermore, an overlap between the pathogen-response and senescence programs is beginning to be characterized. The complexity of the senescence program is also evident in studies of senescence-specific gene regulation and the role of photosynthesis and plant hormones in senescence regulation. New molecular-genetic approaches are expected to be useful in unraveling the molecular mechanisms of the leaf senescence program.

Sequence Analysis Of Bacterial Dna In The Colon And Stomach Of The Tyrolean Iceman, Raul J. Cano, Friedrich Tiefenbrunner, Massimo Ubaldi, Clarissa Del Cueto, Stefania Luciani, Tobe Cox, Paula Orkand, Karl H. Kunzel, Franco Rollo

Biological Sciences

The male human body found in an Alpine glacier on September 19, 1991 ("Tyrolean Iceman") has, for the first time in history, given scientists a chance to perform detailed anatomical, histological, and molecular investigations on the organs of a person from the Neolithic Age (5350-5100 B.P.). In the present study, tissue samples aseptically taken from the stomach and the colon of the mummy were utilized for DNA extraction, and the DNA was PCR-amplified, using primer pairs designed to bind to fragments of the 16s ribosomal RNA gene (16s rDNA) of a broad range of bacteria. The PCR products were cloned …

Wavelet-Based Approach For Structural Damage Detection, Z. Hou, Mohammad N. Noori, R. St. Amand

Office of the Dean (CENG) Scholarship

A wavelet-based approach is proposed for structural damage detection and health monitoring. Characteristics of representative vibration signals under the wavelet transformation are examined. The methodology is then applied to simulation data generated from a simple structural model subjected to a harmonic excitation. The model consists of multiple breakable springs, some of which may suffer irreversible damage when the response exceeds a threshold value or the number of cycles of motion is accumulated beyond their fatigue life. In cases of either abrupt or accumulative damages, occurrence of damage and the moment when it occurs can be clearly determined in the details …

Applying Positive Behavior Support And Functional Behavioral Assessments In Schools, George Sugai, Robert H. Horner, Glen Dunlap, Meme Hieneman, Timothy J. Lewis, C. Michael Nelson, Terrance Scott, Carl Liaupsin, Wayne Sailor, Ann P. Turnbull, H. Rutherford Turnbull, Donna Wickham, Brennan Wilcox, Michael B. Ruef

Graduate Studies in Education

Positive behavior support (PBS) and functional behavioral assessment (FBA) are two significant concepts of the 1997 amendments to the Individuals with Disabilities Education Act. These two concepts are not new, but they are important for improving the quality of efforts to educate children and youth with disabilities. The purposes of this article are to describe (a) the context in which PBS and FBA are needed and (b) definitions and features of PBS and FBA. An important message is that positive behavioral interventions and supports involve the whole school, and successful implementation emphasizes the identification, adoption, and sustained use of effective …

The Effect Of Impact Damage On The Room-Temperature Fatigue Behavior Of Γ-Tial, Trevor S. Harding, J. Wayne Jones

Materials Engineering

The relationship between impact damage and the fatigue behavior of γ-TiAl has been examined. Axial fatigue specimens fabricated from cast Ti-47.9Al-2.0Cr-1.9Nb (to be referred to as 48-2-2) and Ti-47.3Al-2.2Nb-0.5Mn-0.4W-0.4Mo-0.23Si (to be referred to as WMS) alloys were damaged by impact under controlled conditions with a 60 deg wedge-shaped indenter to simulate assembly-related damage in low-pressure turbine blades. The level of damage produced was quantified and found to correlate well with the peak load of the impact event. The WMS alloy exhibited a greater resistance to impact damage due to its higher yield strength and lamellar microstructure. A measure of the …

Smoking Laws And Their Differential Effects On Restaurants, Bars, And Taverns, John Dunham, Michael L. Marlow

Economics

This article examines the effect of restrictive smoking laws on restaurants, bars, and taverns. Supporters of these laws often argue that they do not harm firms and may even raise profits. Opponents argue that owners cater to customer smoking preferences, and laws mandating specific policies will negatively impact profits. This article provides a framework for examining the distribution of effects that smoking laws exert on businesses, and demonstrates that changes in total sales or tax revenues do not provide a meaningful understanding of the economic implications because smoking laws exert different effects on different firms. The distribution of these effects …

Mathematical Devices For Getting A Fair Share: Whether The Problem Involves An Estate, A Cake Or An Opportunity For Regency, Solutions Now Exist For Obtaining An Equitable Division, Theodore P. Hill

Research Scholars in Residence

Since the dawn of history (and certainly before) people have bickered, even battled, over the fair distribution of resources -- for example, the division of estates, disputed territories and the spoils of war. Such dilemmas have for the most part been resolved unilaterally by kings (Solomon and the baby), judges or simple force. Few truly logical solutions evolved. In the past 50 years, however, a number of mathematical devices have been discovered that offer elegant, practical and often surprisingly simple resolutions to many problems of fair-division.

Supplemental Viscous Damping Effects On Seismic Demands Of Linear Elastic Systems, Linda M. Tam, Rakesh K. Goel

Civil and Environmental Engineering

The objective of this study is to examine the effects of viscous supplemental damping on response quantities of asymmetric-plan structures responding in a linearly elastic fashion. The response quantities which will be investigated include: element deformations, base shears, and base torques. These response quantities will be normalized, evaluated, and then analyzed.

It is shown that supplemental damping is indeed effective in reducing element deformations and base torques. In some cases, supplemental damping is also effective in reducing base shears. In order to achieve the largest reduction in flexible element deformation, it is recommended that all fluid viscous dampers be placed …

Peak Flow Responses To Forest Practices In The Western Cascades Of Oregon, Usa, R. L. Beschta, M. R. Pyles, A. E. Skaugset, C. G. Surfleet

Natural Resources Management and Environmental Sciences

The effects of clearcut silviculture (road building, clearfelling, cable logging, and site preparation) were evaluated using long-term peakflow records for three small watersheds (60–101 ha) and six large basins (62–640 km²) in the western Cascades of Oregon, USA. After a calibration period, two of the small watersheds were treated while the third remained untreated (control). Analysis indicated that peakflow increases following treatments were dependent upon peakflow magnitude. Peakflow increases averaged approximately 13–16% after treatment for 1-yr recurrence interval events, and 6–9% for 5-yr recurrence interval events. For the six large basins, multiple linear regression analyses of peakflows relative …

Restricted Words By Adjacencies, Don Rawlings

Mathematics

A recurrence, a determinant formula, and generating functions are presented for enumerating words with restricted letters by adjacencies. The main theorem leads to refinements (with up to two additional parameters) of known results on compositions, polyominoes, and permutations. Among the examples considered are (1) the introduction of the ascent variation on compositions, (2) the enumeration of directed vertically convex polyominoes by upper descents, area, perimeter, relative height, and column number, (3) a tri-variate extension of MacMahon's determinant formula for permutations with prescribed descent set, and (4) a combinatorial setting for an entire sequence of bibasic Bessel functions.
