Human dimensions of ecosystem-based management: Lessons in managing trade-offs from the Northern Shrimp Fishery in Northern Peninsula, Newfoundland
(Elsevier, 2018-11-01)Fisheries can have significant impacts on the structure and function of marine ecosystems, including impacts on habitats and non-target species. As a result, management agencies face growing calls to account for the ecosystem ... -
Semi-continuous measurement of oxygen demand in wastewater using biofilm-capacitance
(Elsevier, 2018-09-01)Bio-capacitive coulombs were tested for determination of the 5-day biochemical oxygen demand (BOD5) using a dual-chamber microbial electrochemical cell (MxC) operated at charging (open circuit) and discharging (close ... -
Self-propulsion of aluminum particle-coated Janus droplet in alkaline solution
(Elsevier, 2018-12-15)Janus droplet motion powered by gas bubbles is studied in this paper. The Janus droplets were fabricated by partially covering one side of an oil droplet with aluminum particles under gravity effect. By placing the Janus ... -
Regional activation of anterior and posterior supraspinatus differs by plane of elevation, hand load and elevation angle
(Elsevier, 2018-12-01)The supraspinatus is one of the muscles of the rotator cuff, and growing research on fibre type composition and mechanical advantages in specific postures suggest this muscle may have distinct anterior and posterior regions. ... -
Modelling farmer choices for water security measures in the Litani river basin in Lebanon
(Elsevier, 2019-01-10)Lebanon is facing an increasing water supply deficit due to the increasing demand for freshwater, decreasing surface and groundwater resources and malfunctioning water governance structures. Technological and policy changes ... -
Poissonian potential measures for Lévy risk models
(Elsevier, 2018-09-01)This paper studies the potential (or resolvent) measures of spectrally negative Lévy processes killed on exiting (bounded or unbounded) intervals, when the underlying process is observed at the arrival epochs of an independent ... -
Financing micro-entrepreneurs for poverty alleviation: a performance analysis of microfinance services offered by BRAC, ASA, and Proshika from Bangladesh
(Springer, 2018-09-18)Microfinance services have emerged as an effective tool for financing microentrepreneurs to alleviate poverty. Since the 1970s, development theorists have considered non-governmental microfinance institutions (MFIs) as the ... -
Research Practices of Civil and Environmental Engineering Scholars at the University of Waterloo
(Ithaka S+R, 2018-09-13)This report is an investigation of research practices of Civil and Environmental Engineering (CEE) scholars at the University of Waterloo. The study was conducted by the Library, and was part of a larger suite of parallel ... -
Spatial Information Enhances Myoelectric Control Performance with Only Two Channels
(Institute of Electrical and Electronics Engineers, 2018-09-10)Automatic gesture recognition (AGR) is investigated as an effortless human-machine interaction method, potentially applied in many industrial sectors. When using surface electromyogram (sEMG) for AGR, i.e. myoelectric ... -
Spin-orbit states of neutron wave packets
(American Physical Society, 2016-07-13)We propose amethod to prepare an entangled spin-orbit state between the spin and the orbital angular momenta of a neutron wave packet. This spin-orbit state is created by passing neutrons through the center of a quadrupole ... -
Holography with a neutron interferometer
(The Optical Society, 2016-10-03)We use a Mach-Zehnder interferometer to perform neutron holography of a spiral phase plate. The object beam passes through a spiral phase plate, acquiring the phase twist characteristic of orbital angular momentum states. ... -
Decoupling of a neutron interferometer from temperature gradients
(AIP Publishing, 2016-12-16)Neutron interferometry enables precision measurements that are typically operated within elaborate, multi-layered facilities which provide substantial shielding from environmental noise. These facilities are necessary to ... -
Neutron interferometer crystallographic imperfections and gravitationally induced quantum interference measurements
(American Physical Society, 2017-01-25)Dynamical diffraction leads to an interesting, unavoidable set of interference effects for neutron interferometers. This experiment studies the interference signal from two and three successive Bragg diffractions in the ... -
Quantum-information approach to dynamical diffraction theory
(American Physical Society, 2016-12-08)We present a simplified model for dynamical diffraction of particles through a periodic thick perfect crystal based on repeated application of a coherent beam-splitting unitary at coarse-grained lattice sites. By demanding ... -
Noise refocusing in a five-blade neutron interferometer
(AIP Publishing, 2017-08-07)We provide a quantum information description of a proposed five-blade neutron interferometer geometry and show that it is robust against low-frequency mechanical vibrations and dephasing due to the dynamical phase. The ... -
Far-field interference of a neutron white beam and the applications to noninvasive phase-contrast imaging
(American Physical Society, 2017-04-26)The phenomenon of interference plays a crucial role in the field of precision measurement science. Waveparticle duality has expanded the well-known interference effects of electromagnetic waves to massive particles. The ... -
Increased interference fringe visibility from the post-fabrication heat treatment of a perfect crystal silicon neutron interferometer
(AIP Publishing, 2018-02-08)We find that annealing a previously chemically etched interferometer at 800 degrees C dramatically increased the interference fringe visibility from 23% to 90%. The Bragg plane misalignments were also measured before and ... -
Experimental search for long-range forces in neutron scattering via a gravitational spectrometer
(American Physical Society, 2014-04-09)In this work we introduce a method of measuring low-energy scattering cross section with a gravitational spectrometer. In this method we add atoms (i.e., He) to the gravitational spectrometer filled with a target gas of ... -
