Occupational sleep medicine is a new field within sleep medicine. Occupational sleep medicine applies (1) the science of sleep, frequently as instantiated into mathematical modeling; (2) the tactics,...
View ArticleApplication of selective laser melting (SLM) for hybrid aerospace structures
The study investigates the adhesion properties of SLM manufactured Titanium (Ti-6Al-4V) alloy surfaces for metal-metal and metal-composite hybrid joints using Mode I Double Cantilever Beam (DCB)...
View ArticleSPIDER on a chip: a phase sensitive ultrafast oscilloscope
We present a device for full waveform characterization, exploiting FWM in a CMOS compatible photonic chip, working with pulse energies as low as 10pJ and with sub-picosecond (<700fs) accuracy over a...
View ArticleA comparative study of vent designs for effective ventilation in cricket helmets
It has been reported that wearing a protective helmet reduces airflow around the head and leads to an increase in heat-related stress and discomfort due to excessive sweat. The main objective of this...
View ArticleOctave spanning mid-IR supercontinuum generation in a silicon-on-sapphire...
We generate a 1.9-4.9 µm supercontinuum in dispersion engineered silicon waveguides with a sapphire substrate. The sapphire substrate allows for extension of the long wavelength edge into the mid-IR by...
View Article3D anthropometric investigation of head and face characteristics of...
Design specialists have acknowledged the need for more accurate measurements of human anthropometry through the use of 3D data, especially for the design of head and facial equipment. However, 3D...
View ArticleUser centred design customisation of bicycle helmets liner for improved...
In order for bicycle helmets to maintain sufficient coverage and protection of riders, the helmets must be adequately positioned and secured on the head. This research investigates helmet's dynamic...
View ArticleComparison of theoretical predictions of radiation efficiency with...
The measurement and prediction of radiation efficiency is important in many areas of acoustics. It has recently become an even more important topic, because the radiation efficiency needs to be known...
View ArticleImpact attenuation of customized user-centered bicycle helmet design
Bicycle helmets are currently available to cater to general head sizes, ranging from S/M and L/XL, but there is also a universal model that can fit all sizes through adjustable helmet strap. Numerous...
View ArticleUsability and Utility: The missing link in evaluation of Healthcare...
This paper examines the role of usability and utility evaluation of information systems used in healthcare. The potential consequences of poor usability and utility are discussed and deficiencies of...
View ArticleMeasurement of high time-bandwidth pulses on a chip with a phase sensitive...
We report a CMOS-compatible monolithic device for the amplitude and phase characterization of ultrafast optical pulses based on FWM, working up to 1THz bandwidth and 100ps time-duration thanks to a new...
View ArticleFishnet metamaterial with double negative refractive index in blue region of...
By optimizing the shape and scale of perforations as well as the depth of different layers, we obtained a metal- dielectric-metal double fishnet metamaterial with an unbroken 38-nm bandwidth of...
View ArticleUltra-low power passive mode-locking using an integrated nonlinear microring...
Using high nonlinear enhancement in a CMOS compatible microring resonator incorporated in a SOA based nonlinear loop-mirror laser architecture, we observe passive modelocking at extremely-low power...
View ArticleEffects of drivers' action on severity of school bus collision
Since parents put their faith in the SB drivers and school divisions to transport their children to and from school safely and these collisions tend to attract a lot of media attention, the safety of...
View ArticleSeverity of single vehicle crashes during holidays
This research examined the effects of different contributing factors on the severity of single vehicle crashes occurring during holidays in the years 1999-2008 in Alberta, Canada. Urban and rural...
