An analytical model for ELDRE

In the following we present a model for ELDRE, simpler than the one proposed in Chapter 4. The purpose is to get reasonable results starting from few physical parameters. References are quite detailed because the work is based on specific results found in the past. In Section 5.1 the main assumptions are explained and the mathematical model is presented. Following Sections investigate the time-...

The Enhanced Low Dose Rate Effect (ELDRE) 4.1 Discovering the ELDRE

4.1 Discovering the ELDRE In 1991 Enlow and coworkers made a comparative study between traditional crystalline emitter transistors (BJTs) and polysilicon emitter transistors (PETs) [1]. The work was intended to study the difference in radiation response of these technologies; indeed at this time large amounts of data were available for crystalline transistors, while very little attention had be...

Building a Potassium MOT

A magneto-optical trap (MOT) was developed in order to cool and trap potassium atoms. This required construction of a mechanism for tuning and locking the frequency of a trap and repump laser in order to maintain the correct energy transitions needed to ensure trapping of the atoms. Once the lasers’ frequencies were locked, the beams were combined and amplified and can now be combined with lase...

SOT for MOT

In this paper we present a robust tracker to solve the multiple object tracking (MOT) problem, under the framework of tracking-by-detection. As the first contribution, we innovatively combine single object tracking (SOT) algorithms with multiple object tracking algorithms, and our results show that SOT is a general way to strongly reduce the number of false negatives, regardless of the quality ...
