Nonscanning climate sensor study
The Nonscanning Climate Sensor represents a new instrument for climate research and global monitoring of the earth radiation budget. It contains a mosaic of array of detectors which measures the outgoing radiation of the earth in all directions without the need for mechanical scanning. The goal is to eliminate all moving parts and obtain highly calibrated measurements for up to one solar cycle (11 years) without being susceptible to mechanical failure. Over set intervals of time, the angular measurements are integrated up to produce total reflected and emitted flux values from each target area on the Earth. To achieve the require sensitivity while maintaining a flat spectral response, an improved dual cavity detector with digital control loop was developed. The detector is self calibrating to maintain high precision over the life of the instrument. Prototype detectors and a complete set of electronics with a microprocessor controller were fabricated and tested. Measurements show that the new detectors are more than an order of magnitude more sensitive than previous versions
Bootstrap percolation on the Hamming torus
The Hamming torus of dimension is the graph with vertices
and an edge between any two vertices that differ in a single
coordinate. Bootstrap percolation with threshold starts with a random
set of open vertices, to which every vertex belongs independently with
probability , and at each time step the open set grows by adjoining every
vertex with at least open neighbors. We assume that is large and
that scales as for some , and study the probability
that an -dimensional subgraph ever becomes open. For large , we
prove that the critical exponent is about for , and
about for . Our small
results are mostly limited to , where we identify the critical in
many cases and, when , compute exactly the critical probability that
the entire graph is eventually open.Comment: Published in at http://dx.doi.org/10.1214/13-AAP996 the Annals of

The Effects of an Active Student Council on Total Student Body Behavior
This paper represents a study of the activation of iii a student council and its effects on total school climate. The activation program was outlined with specific activities described in detail. The study was designed to provide for a comparison of predetermined indicators which were measured before and after the activation took place. Conclusions included positive observations made during the course of the study and recommendations for implementing more student involvement in the ongoing business of the school
