Agriculture and the threat to biodiversity in sub-saharan Africa
(2015)The Millennium Ecosystem Assessment identified habitat loss due to the extensive growth of agriculture as the primary driver of biodiversity loss. One implication of this is that agricultural intensification has the potential ... -
An artificial neural network architecture for non-parametric visual odometry in wireless capsule endoscopy
(2017)Wireless capsule endoscopy is a non-invasive screening procedure of the gastrointestinal (GI) tract performed with an ingestible capsule endoscope (CE) of the size of a large vitamin pill. Such endoscopes are equipped with ... -
Can Existing Design Codes Be Used to Design Flexural Reinforced Concrete Elements Strengthened with Externally Bonded Novel Materials?
(2018)The use of composite overlays to strengthen or rehabilitate existing structural elements has been investigated over the past few decades. The most common composites that were used are based on Glass or Carbon fibers ... -
Comparative analysis of methods for extracting vessel network on breast MRI images
(2017)Digital processing of MRI images aims to provide an automatized diagnostic evaluation of regular health screenings. Cancerous lesions are proven to cause an alteration in the vessel structure of the diseased organ. Currently ... -
Computation of the effective area and associated uncertainties of non-rotating piston gauges FPG and FRS
(2019)The effective areas of three force-balanced piston gauges (FPGs) and two Furness Rosenberg standards (FRS) in the operating pressure range of each device varying for 1 Pa-15 kPa have been accurately computed both in the ... -
Computational study of the effect of gradient magnetic field in navigation of spherical particles
(2017)The use of spherical magnetic nanoparticles that are coated with drugs and can be navigated in arteries to attack tumors is proposed as an alternative to chemotherapy. Navigation of particles is due to magnetic field ... -
Computational study of the optimum gradient magnetic field for the navigation of spherical particles into targeted areas
(2015)Spherical magnetic nanoparticles coated with drugs are navigated to targeted areas, for the treatment of cancer. The particles are navigated by magnetic field gradients that can be produced by an MRI device. In the present ... -
Constraining the Asymptotically Safe cosmology: Cosmic acceleration without dark energy
(2019)A recently proposed Asymptotically Safe cosmology provides an elegant mechanism towards understanding the nature of dark energy and its associated cosmic coincidence problem. The underlying idea is that the accelerated ... -
Current phase relation from graphs and diagrams and application to thick ferromagnetic Josephson junctions
(2018)In this work we present a method of representing terms in the current-phase-relation of a ballistic Josephson junction by combinations of diagrams, used in previous work to represent an equivalent of the matching condition ... -
Development of silicon detectors for Beam Loss Monitoring at HL-LHC
(2017)Silicon detectors were proposed as novel Beam Loss Monitors (BLM) for the control of the radiation environment in the vicinity of the superconductive magnets of the High-Luminosity Large Hadron Collider. The present work ... -
Direct numerical simulation of particle-laden turbulent channel flows with two- and four-way coupling effects: Budgets of Reynolds stress and streamwise enstrophy
(2016)The budgets of the Reynolds stress and streamwise enstrophy are evaluated through direct numerical simulations for the turbulent particle-laden flow in a vertical channel with momentum exchange between the two phases. The ... -
Direct numerical simulation of particle-laden turbulent channel flows with two- and four-way coupling effects: Models of terms in the Reynolds stress budgets
(2017)In the first part of this study (Dritselis 2016 Fluid Dyn. Res. 48 015507), the Reynolds stress budgets were evaluated through point-particle direct numerical simulations (pp-DNSs) for the particle-laden turbulent flow in ... -
The effect of the daylight zone on lighting energy savings
(2020)Daylighting is the cornerstone of low energy building design. Therefore, the adoption of a daylight - harvesting lighting control system can substantially increase lighting energy savings. These are strongly depended on ... -
The electromagnetic environment of Magnetic Resonance Imaging systems. Occupational exposure assessment reveals RF harmonics
(2015)Magnetic Resonance Imaging (MRI) systems played a crucial role in the postponement of the former occupational electromagnetic fields (EMF) European Directive (2004/40/EC) and in the formation of the latest exposure limits ... -
Endoscopic single-image size measurements
(2020)In the practice of clinical gastrointestinal endoscopy, precise estimation of the size of a lesion/finding, such as a polyp, is quintessential in diagnosis, e.g. risk estimation for malignancy. However, various studies ... -
