Using ordinary multiplication to do relativistic velocity addition

Relativistic addition of velocities in one dimension, though a mainstay of introductory physics, contributes much less physical insight than it could. For such calculations, we propose the use of velocity factors (two-way doppler factors). Velocities can easily, often by inspection, be turned into velocity factors, and vice versa. Velocity factors compose by ordinary multiplication. This simple device considerably extends the kinds of questions that can be asked and answered in an introductory course.Comment: 6 page

Standalone Track Reconstruction in the T-stations

An algorithm for fast and efficient tracking in the T-stations is describedtogether with its performance in the DC06 data challenge. An efficiency of94--$95~\%$ is achieved for tracks with momenta above 2~GeV for a ghost rate of $13~\%$

Corundum-Hibonite Inclusions and the Environments of High Temperature Processing in the Early Solar System

Calcium, Aluminum-rich inclusions (CAIs) are composed of the suite of minerals predicted to be the first to condense from a cooling gas of solar composition [1]. Yet, the first phase to condense, corundum, is rare in CAIs, having mostly reacted to form hibonite followed by other phases at lower temperatures. Many CAIs show evidence of complex post-formational histories, including condensation, evaporation, and melting [e.g. 2, 3]. However, the nature of these thermal events and the nebular environments in which they took place are poorly constrained. Some corundum and corundum-hibonite grains appear to have survived or avoided these complex CAI reprocessing events. Such ultra-refractory CAIs may provide a clearer record of the O isotopic composition of the Sun and the evolution of the O isotopic composition of the planet-forming region [4-6]. Here we present in situ O and Mg isotopic analyses of two corundum/hibonite inclusions that record differing formation histories

Updated Performance of the T-Seeding

Improvements to the performance of the track seeding since the start of the DC '06 data challenge are described. For tracks above 2~GeV an efficiency of $96.3~\%$ is achieved for a ghost rate of 8.1~\%. In addition, the expected performance of the algorithm during the 2007 pilot run is discussed

Back flushing on milking machine teat cups

THE possibility of replacing the dipping of teat cups between cows with a system of back flushing with water has been investigated for some time by different workers
