Triangulating the height of cosmic noise absorption: A method for estimating the characteristic energy of precipitating electrons [PDF]

open access: yes, 2010
Energetic electrons (tens to hundreds of keV) deposit significant energy into the D layer of the ionosphere. Riometers provide a means of monitoring this electron precipitation by measuring the associated cosmic noise absorption (CNA), but individually ...

Geometric and scale effects on energy absorption of structural composites [PDF]

open access: yes, 2011
PhDThe challenge faced by structural designers is becoming increasingly difficult as the imposed design criteria of energy absorbing structures requires weight reduction of structures without compromising cost and crushing performance.

The development and calibration of a generic dynamic absorption chiller model [PDF]

open access: yes, 2012
Although absorption cooling has been available for many years, the technology has typically been viewed as a poorly performing alternative to vapour compression refrigeration.

High-resolution maps of the characteristic energy of precipitating auroral particles [PDF]

open access: yes, 2001
For the first time we produce high-resolution maps of the characteristic energy of precipitating electrons from ground-based instrumentation in the auroral zone over northern Scandinavia. This is done by combining intensity-calibrated optical data at 557.

Technoeconomic evaluation of trigeneraton plant: Gas turbine performance, absorption cooling and district heating [PDF]

open access: yes, 2006
This PhD thesis is a demand led study taking into account changes in ambient conditions and power settings of a tri-generation power plant. Includes an evaluation tool for combined heat, cooling and power generation plant.

Speed and Temperature Effects in the Energy Absorption of Axially Crushed Composite Tubes [PDF]

open access: yes, 2008
Tubes of glass reinforced thermosetting resins have been tested in axial compression between steel platens with one end chamfered to prevent critically high loads causing catastrophic centre failure.

The Influence of Multiscale Fillers Rein forcement into Impact Resistance and Energy Absorption Properties of Polyamide 6 and Polypropylene Nanocomposite Structures [PDF]

open access: yes, 2013
Three-phase composites (thermoplastic polymer, glass-fibres and nano-particles) were investigated as an alternative to two-phase (polymer and glass-fibres) composites.

Mechanical energy absorption of architecturally interlocked petal-schwarzites

open access: yesCarbon Trends, 2023
We carried out fully atomistic reactive molecular dynamics simulations to study the mechanical behavior of six newly proposed hybrid schwarzite-based structures (interlocked petal-schwarzites).
