Multi-gigawatt peak power post-compression in a bulk multi-pass cell at a high repetition rate
(2022-09-27)The output of a 200 kHz, 34 W, 300 fs ytterbium amplifier is compressed to 31 fs with >88% efficiency to reach a peak power of 2.5 GW, which to date is a record for a singlestage bulk multi-pass cell. Despite operation ... -
Multi-instrument comparisons of D-region plasma measurements
(2013)The ECOMA (Existence and Charge state Of Meteoric dust grains in the middle Atmosphere) series of sounding rocket flights consisted of nine flights with almost identical payload design and flight characteristics. All flights ... -
Multi-phase performance evaluation for modern minehunting systems
(2019-05-10)Many NATO navies are in the process of replacing their dedicated minehunting vessels with systems of heterogeneous, unmanned modules. While traditional ship-based assets prosecute sonar contacts in sequence through to ... -
Multi-watt, multi-octave, mid-infrared femtosecond source
(2018)Spectroscopy in the wavelength range from 2 to 11 μm (900 to 5000 cm−1) implies a multitude of applications in fundamental physics, chemistry, as well as environmental and life sciences. The related vibrational transitions, ... -
Multiband Passive Bistatic Radar Coherent Range and Doppler-Walk Compensation
(2015)The work simulates the performance of a coherent Passive Bistatic Radar multiband processing algorithm. The aim of the work is to present improved range resolution by coherently combine non-adjacent DVB-T channels, while ... -
Multibeam Echosounder With Orthogonal Waveforms: Feasibility and Potential Benefits
(2021-04-15)Modern multibeam echosounders (MBE) employ frequency-division techniques (FDT) to ensonify multiple sectors within the same ping cycle. This leads to improved performance in coverage rate, and yaw and pitch stabilization. ... -
Multichannel open tubular enzyme reactor online coupled with mass spectrometry for detecting ricin
(2017)For counterterrorism purposes, a selective nano liquid chromatography–mass spectrometry (nanoLC-MS) platform was developed for detecting the highly lethal protein ricin from castor bean extract. Manual sample preparation ... -
Multimodal change monitoring using multitemporal satellite images
(2021-09-12)The main objective of this study is to monitor the land infrastructure growth over a period of time using multimodality of remote sensing satellite images. In this project unsupervised change detection analysis using ITPCA ... -
Multimodal Multispectral Imaging System for Small UAVs
(2020-01-17)Multispectral imaging is an attractive sensing modality for small unmanned aerial vehicles (UAVs) in numerous applications. The most compact spectral camera architecture is based on spectral filters in the focal plane. ... -
Multiple episodes of fluid flow in the SW Barents Sea (Loppa High) evidenced by gas flares, pockmarks and gas hydrate accumulation
(2012)Gas and gas hydrates have gained considerable attention in the last 20 yr due to their possible impact on global climate change from methane escalations. Our study area, the SW Barents Sea, is unique in its evolution due ... -
Multiple-array passive acoustic source localization in shallow water
(2017)This paper considers concurrent matched-field processing of data from multiple, spatially-separated acoustic arrays with application to towed-source data received on two bottom-moored horizontal line arrays from the SWellEx-96 ... -
Multiplex polymerase chain reaction detection of enteropathogens in sewage in Norway
(2019-03-04)The primary objective of this small-scale study was to investigate the occurrence of enteropathogens in sewage (municipal wastewater) in Norway using the commercially available FilmArray® multiplex polymerase chain reaction ... -
A Multiscale Wavelet-Based Test for Isotropy of Random Fields on a Regular Lattice
(2015)A test for isotropy of images modeled as stationary or intrinsically stationary random fields on a lattice is developed. The test is based on the wavelet theory, and can operate on the horizontal and vertical scale of ... -
Multiteam Systems Handling Time-Sensitive Targets: Developing Situation Awareness in Distributed and Co-located Settings
(2022-08-04)There is an increasing interest in how to organize operations carried out by multiteam systems (MTS). Large MTS typically operate with a dedicated integration team, responsible for coordinating the operation. We report a ... -
