An investigation of Roman mortar technology through the petrographic analysis of archaeological material
(Elsevier, 2007)This paper studies Roman mortars to demonstrate that petrographic analysis provides valuable information on ancient mortar technology. Facts on lime technology relating calcination and slaking were obtained through ... -
Investigation of the effect of low-temperature annealing and impact angle on the erosion performance of nickel-tungsten carbide cold spray coating using design of experiments
(2022)This study investigates the solid particle erosion performance of cold sprayed tungsten carbide-nickel coatings using alumina particles as erodent material. After the coatings fabrication, specimens were annealed in an ... -
The investigation of the relaxation processes in antiferroelectric liquid crystals by electro-optic spectroscopy
(American Institute of Physics, 1998)Electrooptic spectroscopy of an antiferroelectric liquid crystal is carried out over a range of frequencies from 1 Hz to 100 kHz. In the antiferroelectric SmCA phase two relaxation processes are found, one at the fundamental ... -
Investigation on autonomous healing for GFRP composite using cyanoacrylate adhesives
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2012)An investigation into smart structures with a vascular healing system using cyanoacrylate (CA) adhesive is presented in this thesis. The flexibility in the functional role of a smart structure involves the structure executing ... -
Investigation on parametrically excited motions of point absorbers in regular waves.
(2016)Free floating objects such as a self - reacting wave energy converter (WEC), may experience a condition known as parametric resonance. In this situation, at least two degrees of freedom become coupl ed when the ... -
An investigation on powder stream in Cold Gas Spray (CGS) nozzles
(2011)The exponential increase of industrial demand in the past two decades has led scientists to th e development of alter native technologies for th e fast manufacturing of engineering components, aside from standar d ... -
Investigations into the mechanical properties of insect cuticle
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2016)Insect cuticle is a composite material comprised of chitin fibres embedded in a protein matrix. It performs a wide variety of functions across class Insecta, and as such displays a wide bandwidth of material properties. ... -
Investigations of nano-scale helical pitch in SmCá* and SmC* phases of a chiral smectic liquid crystal using differential optical reflectivity measurements
(2006)Differential optical reflectivity (DOR) was used to study the temperature dependence of the short helical pitch in freestanding films of a liquid crystal compound. The experimentally measured DOR signal was fitted using ... -
Investigations of nanoscale helical pitch in smectic-C and smectic-C* phases of a chiral smectic liquid crystal using differential optical reflectivity measurements
(2006)Differential optical reflectivity DOR was used to study the temperature dependence of the short helical pitch in freestanding films of a liquid crystal compound. The experimentally measured DOR signal was fitted using ... -
Investigations on rare-earth doped alumino-silicate xerogel incorporated in micro-channel glass and porous silicon
(2005)Porous materials in general have received great attention from the last century. The development of new porous materials and the preparation of new composites based on porous materials is a subject of interest. The development ... -
Investigations on the effect of non-linear models on the reliability of partial safety factor designs
(2023)Most modern structural design codes, such as the Eurocode, are based on the partial safety factor concept. The partial safety factors are calibrated on linear limit states. They provide simplified rules on the application ... -
IoT and AI-Driven Audio in the Smart City: A Rhythmanalysis inspired approach
(2018)French Philosopher and theorist Henri Lefebvre's The Production of Space (1991) has proved a crucial text for framing the discourse around contemporary urban society in the fields of human geography, critical theory, ... -
An IoT Approach for Monitoring UV Disinfection Robots
(2021)The use of ultraviolet germicidal irradiation (UVGI) technology as a means of disinfecting hospitals and other frontline settings has increased significantly in the wake of the COVID-19 pandemic. Although the science of ... -
Irish Researchers Develop Automated Anisotropic Test Kit
(2003)A hollow cylinder apparatus for measuring anisotropic soil behaviour has been developed by researchers at the National University of Ireland, Dublin. Dr Brendan O'Kelly and Pat Naughton said the automated apparatus ... -
Isolating neural indices of continuous speech processing from multivariate neural data
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2017)The human ability to understand speech is underpinned by a hierarchical auditory system whose successive stages process increasingly complex attributes of the auditory input. To produce categorical speech perception, it ... -
