\u27Texas Maroon’ Bluebonnet

The Texas state flower, the bluebonnet, encompasses all six of the Lupinus species native to Texas. The most widespread and popular bluebonnet, Lupinus texensis Hook., is a winter annual that produces violet-blue [violet-blue group 96A, Royal Horticultural Society (RHS), 1982] racemes in early to midspring and is predominately self-pollinating. The Texas Dept. of Transportation uses this species widely for floral displays along roadsides throughout much of the state (Andrews, 1986). Rare white and even rarer pink variants exist in native populations, and a breeding project was initiated in 1985 to develop bluebonnets with novel flower colors for use as bedding plants. ‘Abbott Pink’ was the first seed-propagated cultivar to be developed from this program (Parsons and Davis, 1993). The second cultivar, ‘Barbara Bush’ with novel lavender shade flowers, was developed more recently (Parsons et al., 1994). As with the cultivars previously developed, we used recurrent phenotypic selection to develop ‘Texas Maroon’. This cultivar is intended for use as a bedding plant for maroon flower color

An Improved Flight Simulator Graphics System Using Microcomputer Technology

The field of computer graphics has continued to provide an efficient means of depicting information about complex phenomena for its users. It has become a widely used tool through which the user may manipulate data to generate a different perspective of the problem at hand and, hence, offers a solution to many varied problems. One area of the application for computer graphics is the field of flight simulation. At the University of Central Florida, research is being conducted in the area of computer graphics simulation to develop a method through which a pictorial representation of the outline of a small airport runway may be modified to appear as viewed by a pilot in a defined airspace. The purpose of this paper is to provide a means of interfacing a small computer to a flight simulator device as well as a graphics terminal. This new implementation of the software will allow a pictorial display to be continuously modified by the changing positional and attitudinal parameters provided from a flight simulator\u27s input. Another goal of this paper is to generate faster display turnaround times by programming the computer in assembly language. Further, the hardware that accomplishes this task is discussed. Finally, suggestions for continued research in this area conclude the report

A new era of wide-field submillimetre imaging: on-sky performance of SCUBA-2

SCUBA-2 is the largest submillimetre wide-field bolometric camera ever built. This 43 square arc-minute field-of-view instrument operates at two wavelengths (850 and 450 microns) and has been installed on the James Clerk Maxwell Telescope on Mauna Kea, Hawaii. SCUBA-2 has been successfully commissioned and operational for general science since October 2011. This paper presents an overview of the on-sky performance of the instrument during and since commissioning in mid-2011. The on-sky noise characteristics and NEPs of the 450 and 850 micron arrays, with average yields of approximately 3400 bolometers at each wavelength, will be shown. The observing modes of the instrument and the on-sky calibration techniques are described. The culmination of these efforts has resulted in a scientifically powerful mapping camera with sensitivities that allow a square degree of sky to be mapped to 10 mJy/beam rms at 850 micron in 2 hours and 60 mJy/beam rms at 450 micron in 5 hours in the best weather.Comment: 18 pages, 15 figures.SPIE Conference series 8452, Millimetre, Submillimetre and Far-infrared Detectors and Instrumentation for Astronomy VI 201

The Impact of COVID-19 on Wildlife Strike Rates in the United States

Shortly after the COVID-19 pandemic impacted air traffic, industry bodies warned of the potential increase in wildlife strike risk. Prior to the pandemic, wildlife strikes were already a concern to the industry. We sought to evaluate industry warnings using interrupted time series analysis of wildlife strike trends in the United States. Using pre-pandemic wildlife strike trends, we compared a forecast of the expected monthly strike rates through the COVID-19 impact period (March 2020 to December 2020) to the actual wildlife strike rates for the same period. Our results showed an increase in wildlife strike rates in 5 out of the 10 months analyzed, supporting the need for careful consideration of wildlife strike risk through the industry’s recovery
