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...
متن کاملSOT 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 ...
متن کاملTheory for Searching in a Thesau- rus
In this article we present a framework based on Situation Theory which models the Query by Navigation process in a Hypertext environment. Descriptors in the Hyperindex are transformed to so-called infons. Documents in the Hyperbase are represented as situations, which can support infons. Similarly, search paths are modeled as a number of followed information links between the infons expressing ...
متن کاملThe Elasticity Coefficients Measurement of Human Dentin Based on RUS
This paper proposed to take advantages of resonant ultrasound spectroscopy (RUS) to measure the mechanical properties of human dentin specimen. The resonant spectroscopy of the dentin specimen was obtained between the frequency bands 155 and 575 kHz, and resonant frequencies were extracted by linear predictive filter and then by Levenberg-Marquardt method. By inverse problem approach, 13 experi...
متن کاملKinFu MOT: KinectFusion with Moving Objects Tracking
Using a depth camera, the KinectFusion algorithm permits tracking the camera poses and building a dense 3D reconstruction of the environment simultaneously in real-time. We present an extension to this algorithm that allows additionally the concurrent tracking and reconstruction of several moving objects within the perceived environment. This is achieved through an expansion of the GPU processi...
