Single Dish Polarization Calibration

Using the formalism of Hamaker et al. (1996), I derive a method for the polarization calibration of observations made with a single radio telescope. This method is particularly appropriate for observations of pulsars, where the sign and magnitude of the circular polarization are useful for understanding the emission processes at work. I apply the method to observations of PSR J1359–6038 made us...

Parabolic Dish Microphone

A parabolic dish microphone is like a mirror telescope for sound. A parabolic reflector is used to collect and focus sound waves to a microphone receiver [1, 2]. The parabolic shape has the property that all sound waves impinging parallel to the central axis of the dish are reflected to its focus point. When the dish is aimed at a distant sound source it is safe to assume that all the sound wav...

DISH: Distributed Self-Healing

Unattended wireless sensor networks (UWSNs) operating in hostile environments face the risk of compromise. Unable to off-load collected data to a sink or some other trusted external entity, sensors must protect themselves by attempting to mitigate potential compromise and safeguarding their data. In this paper, we focus on techniques that allow unattended sensors to recover from intrusions by s...

A Micro-Glucide Dish.

The difficulties met in endeavoring to obtain chemically pure products have incited us to try to develop a micro-technique for the study of carbohydrate fermentation by bacteria. By this technique, used by us since 1941 and involving over five hundred different strains, we have found that we gained much room in our incubators, made a notable saving of time in the preparation of the material, in...
