Development of Detector System with Small Cell Multi-wire Drift Chamber

Yuanzineng kexue jishu
In order to accurately measure the path of the incident particles in front of the target at the CSR outer target terminal, multiple sets of small cell multi-wire drift chamber detectors were developed with a drift cell of 5 mm. The sensitive area of this

Effects of the Detection Efficiency on Multiplicity Distributions

, 2013
In this paper we investigate how a finite detection efficiency affects three popular multiplicity distributions, namely the Poisson, the Binomial and the Negative Binomial distributions.

Necessary and sufficient detection efficiency for the Mermin inequalities

, 2008
We prove that the threshold detection efficiency for a loophole-free Bell experiment using an $n$-qubit Greenberger-Horne-Zeilinger state and the correlations appearing in the $n$-partite Mermin inequality is $n/(2n-2)$.

Measurement of neutron detection efficiency between 22 and 174 MeV using two different kinds of Pb-scintillating fiber sampling calorimeters

, 2009
We exposed a prototype of the lead-scintillating fiber KLOE calorimeter to neutron beam of 21, 46 and 174 MeV at The Svedberg Laboratory, Uppsala, to study its neutron detection efficiency.

Vision-Aided Hyperspectral Full-Waveform LiDAR System to Improve Detection Efficiency

Remote Sensing, 2023
The hyperspectral full-waveform LiDAR (HSL) system based on the supercontinuum laser can obtain spatial and spectral information of the target synchronously and outperform traditional LiDAR or imaging spectrometers in target classification and other ...

Security proof of quantum key distribution with detection efficiency mismatch [PDF]

, 2008
In theory, quantum key distribution (QKD) offers unconditional security based on the laws of physics. However, as demonstrated in recent quantum hacking theory and experimental papers, detection efficiency loophole can be fatal to the security of ...

High efficiency compression for object detection

, 2018
Image and video compression has traditionally been tailored to human vision. However, modern applications such as visual analytics and surveillance rely on computers seeing and analyzing the images before (or instead of) humans.

Efficient and robust shot change detection [PDF]

Journal of Real-Time Image Processing, 2007
In this article, we deal with the problem of shot change detection which is of primary importance when trying to segment and abstract video sequences. Contrary to recent experiments, our aim is to elaborate a robust but very efficient (real-time even with uncompressed data) method to deal with the remaining problems related to shot change detection ...
