Design of a Microwave Power Detection System in the 5G-Communication Frequency Band

open access: yesSensors, 2021
At present, the proposed microwave power detection systems cannot provide a high dynamic detection range and measurement sensitivity at the same time. Additionally, the frequency band of these detection systems cannot cover the 5G-communication frequency

Low Dynamic Range Solutions to the High Dynamic Range Imaging Problem

open access: yesJournal of Measurement Science and Instrumentation, 2010
While capturing a real world scene using a common digital camera,due to limitations of the sensor dynamic range,we will not be able to capture the entire dynamic range of the scene.This problem is evident while capturing a picture of a scene which has ...

Suppression and the dynamic range of hearing [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1992
The results from experiments that have examined intensity discrimination in the presence of notched noise indicate that spread of excitation is not necessary for the auditory system to maintain a large dynamic range. In these experiments, however, the notched noise and the pedestal were simultaneously present.

Dynamic range majority data structures [PDF]

open access: yesTheoretical Computer Science, 2011
Given a set $P$ of coloured points on the real line, we study the problem of answering range $α$-majority (or "heavy hitter") queries on $P$. More specifically, for a query range $Q$, we want to return each colour that is assigned to more than an $α$-fraction of the points contained in $Q$.

Dynamic Range Mode Enumeration

open access: yesCoRR, 2021
The range mode problem is a fundamental problem and there is a lot of work about it. There is also some work for the dynamic version of it and the enumerating version of it, but there is no previous research about the dynamic and enumerating version of it. We found an efficient algorithm for it.
