[1] A unique morphology suggestive of viscous flow of a meters-thick surface layer was identified in high-resolution (<10 m/pixel) Mars Orbiter Camera (MOC) images. A global survey of 13,000 MOC images resulted in the identification of 146 images exhibiting these viscous flow features. Slope angles derived from Mars Orbiter Laser Altimeter (MOLA) data, along with an experimentally derived flow ...

16. Abstract The Oregon Department of Transportation (ODOT) has recently begun changing their standard traffic signal control systems from the 170 controller running the Wapiti W4IKS firmware to 2070 controllers operating the Northwest Signal Supply Corporation's Voyage software. Concurrent with this change in standard signal control systems, ODOT has taken the opportunity to install test sites...

Problem definition: A stopped-meter is a meter that reports zero during a predefined period of time. The zero report can occur for two reasons: either the meter is faulty or else there is legitimate zero-consumption in the property. The usual solution is to send a technician after a predefined period of time, but the problem is how to determine the optimum period of time. If the period is too s...

here has been much excitement below our so-called top band at 1.8 MHz. At less than one-tenth this frequency, near 136 kHz, you will find many amateurs enjoying QSOs using a variety of modes. Although US and Canadian amateurs need special permission to transmit here, there is a 2200 meter amateur band in many European countries and in New Zealand. Aside from its low frequency, the most striking...
