Engineering self healing capacity of cement based materials through crystalline admixtures

open access: yes, 2015
In this paper aims a thorough characterization will be performed of the effects of crystalline admixtures, currently employed as porosity reducing admixtures, on the self-healing capacity of the cementitious composites, i.e.

Data compression in ViSAR sensor networks using non-linear adaptive weighting

open access: yesEURASIP Journal on Wireless Communications and Networking, 2019
Nowadays, industrial video synthetic aperture radars (ViSARs) are widely used for aerial remote sensing and surveillance systems in smart cities. A main challenge of a group of networked ViSAR sensors in an IoT-based environment is low bandwidth of ...

Single Channel Slow Moving Target Detection Method for Terahertz Video Synthetic Aperture Radar Based on Shadows and Spots

open access: yesRemote Sensing
Terahertz waves are located in the “transition zone” between millimeter waves and infrared light. Terahertz video synthetic aperture radar (THz-ViSAR) utilizes the high operating frequency, strong radar cross-section intensity, and high azimuth ...

Motstånd, Motkultur och Miljöfrågor: En etnografisk studie av ungdomars reaktioner mot utbildning och hållbar utveckling

open access: yesNordisk Tidsskrift for Ungdomsforskning
Miljö- och hållbarhetsfrågor kan vara värdeladdade, skapa konflikter och ge upphov till motstånd, vilket också märks bland ungdomar. Detta blir särskilt tydligt inom miljö- och hållbarhetsutbildning.

High Pressure Hugoniot Measurements in Solids Using Mach Reflections [PDF]

open access: yes, 2011
Shock compression experiments provide access to high pressures in a laboratory setting. Matter at extreme pressures is often studied by utilizing a well controlled planar impact between two flat plates to generate a one dimensional shock wave.

Speckle-adaptive VISAR fringe analysis technique [PDF]

open access: yesAIP Conference Proceedings, 2017
A line-VISAR (velocity interferometer) is an important diagnostic in shock physics, simultaneously measuring many fringe histories of adjacent portions of a target splayed along a line on a target, with fringes recorded vs time and space by a streak camera.

A numerical model for the self-healing capacity of cementitious Composites

open access: yes, 2014
The self-healing capacity of cementitious composites, i.e. their capacity to completely or partially re-seal cracks, is studied in this paper. This phenomenon is investigated with reference to a previous experimental campaign dealing with a normal ...

A method for diagnosing the implosion symmetry in inertial confinement fusion with wide-angle VISAR

open access: yesNuclear Fusion
A method for diagnosing implosion symmetry in inertial confinement fusion (ICF) with wide-angle velocity interferometer system for any reflector (VISAR)was proposed in this study. The method considers the object-image relationship of the wide-angle VISAR,
