Vortex drop shaft structures: state-of-the-art and future trends
(International Association for Hydro-Environment Engineering and Research (IAHR), 2019-09-01)
Vortex drop shaft structures have played a critical role in hydraulic engineering; from one of their first
applications in hydroelectric energy dissipation in the 1940s, to numerous contemporary installations throughout
modern ...
Privacy challenges for smart-cities: The challenge of IoT camera uberveilance
(IEEE World Forum on Internet of Things, 2019-04-15)
The challenges of handling personal privacy are examined in the context of a smart-city environment with every-present surveillance. The current state of digital camera technology is reviewed and two over-arching approaches ...
Use of nondestructive techniques for determination of tension parallel-to-grain properties of spruce
(USDA Forest Service Forest Products Laboratory (FPL), 2019-09-25)
The paper presents a study of the tension properties of Irish-grown Sitka spruce. Fifty timber pieces were destructively tested having resonant frequency and knots measured. The aim was to improve knowledge of the performance ...
Numerical study of FRP reinforced timber members subjected to variable climates
(SHATiS International Conference on Structural Health Assessment of Timber Structures, 2019-09-25)
The use of FRP reinforcement, even in small percentages, has been shown to improve the short-term flexural behaviour of timber members. This technology has been successfully used in new construction and in the repair and ...
Early-stage dielectric characterisation of renal cell carcinoma for positive surgical margin detection
(Institute of Electrical and Electronics Engineers, 2019-03-31)
Partial nephrectomy is preferred to total nephrectomy tor clinically localised renal cell carcinoma. In order to minimise the risk of local tumour recurrence after partial nephrectomy, ideally, the surgical margins of the ...
Comparison of coaxial open-ended probe based dielectric measurements on ex-vivo thermally ablated liver tissue
(Institute of Electrical and Electronics Engineers, 2019-03-31)
This paper compares an in-house dielectric properties measurement system based on the "Stuchly and Stuchly" method with the broadly commercialised Keysight setup and existing literature for the characterization of ablated ...
Microwave thermal ablation: focusing energy in target tissue using fat layer
(Institute of Electrical and Electronics Engineers, 2019-03-31)
Microwave thermal ablation therapy is a minimally invasive technique introduced in the interventional oncology practice to treat a range of cancerous pathologies. Whereas satisfying results are obtained with the treatment ...
Sensing radius of an open-ended coaxial probe for dielectric measurement of tissues: Calculation with relative permittivity versus conductivity
(Institute of Electrical and Electronics Engineers, 2019-03-09)
The dielectric properties of biological tissues are important parameters used in the design and optimisation of electromagnetic-based medical technologies. Typically, these parameters are measured ex-vivo using the open-ended ...
Investigating human bone microarchitecture and dielectric properties in microwave frequency range
(Institute of Electrical and Electronics Engineers, 2019-03-31)
Dielectric properties of bones are proposed to monitor bone quality. However, no study has investigated the relationship between bone dielectric properties and microarchitecture of bone, which is of paramount importance ...
