INSIGHT INTO GLOBAL GROUND-LEVEL AIR QUALITY USING SATELLITES, MODELING AND IN SITU MEASUREMENTS
(2015)
Ground-level air quality depends on the ambient concentration of atmospheric aerosols and trace gases. We applied information on aerosols and trace gases gathered from satellite remote sensing, in situ observations, and ...
Solar Absorption Spectroscopy at the Dalhousie Atmospheric Observatory
(2015)
A newly refurbished high-resolution Fourier Transform Spectrometer (FTS) has been installed at the Dalhousie Atmospheric Observatory (DAO) to monitor the outflow of trace gases leaving North America. Regular solar absorption ...
PIP: A (Privacy) Injection Pattern for Inserting Privacy Patterns and Services in Software
(2015)
Sensitive data may be leaked in many ways, and misuse of personal data from information systems is very common. It is challenging to implement privacy services in existing applications without affecting other modules. We ...
The influence of dietary fat concentration on fatty acid signatures and stable carbon isotopes of fatty acids in liver of Atlantic pollock (Pollachius virens)
(2015)
A number of biomarker techniques have been employed to investigate animal diets, including analyses of fatty acid (FA) proportions and stable carbon isotopic signatures. Here, the influence of dietary FA concentrations on ...
Orthognathic Surgery and Peri Operative Antibiotic Use
(2015)
Purpose : The purpose of this study was to determine the most effective duration of antibiotic prophylaxis following orthognathic surgery.
Methods: A survey of Canadian Oral and Maxillofacial surgeons (OMFS), a retrospective ...
DIFFERENTIAL CODE SHIFT REFERENCE IMPULSE RADIO ULTRA-WIDEBAND TRANSCEIVER: BIT ERROR RATE TESTS AND PERFORMANCE ASSESSMENTS
(2015)
Impulse radio is a wireless communication technique in which ultra-short pulses in the range of nano-seconds are used for the transmission of information. These ultrashort pulses spread over the radio frequency spectrum ...
An Application of Mathematical Optimization to Autoclave Packing and Scheduling in a Composites Manufacturing Facility
(2015)
An industry problem regarding autoclave packing and scheduling in a composites manufacturing facility is examined. The hill-climbing method is modified and applied to solving the packing of autoclaves, which is a modified ...
Non-Linear Coupling of Scales of Ocean Variability and Implications for Downscaling
(2015)
The objectives of this study are to develop better methods for dynamically downscaling ocean conditions, and to improve understanding of the physical processes controlling variations on regional scales.
Motivated by the ...
Investigating the generation efficiency, growth and structure of flocs produced by electrocoagulation
(2015)
Electrocoagulation (EC) is a water treatment technology that releases metal cations into solution from sacrificial anodes. Compared to chemical coagulation (CC), EC’s advantages (e.g., solid metal electrodes, reduced ...
Sparse Directional Estimation of the Time-Varying Underwater Acoustic Channel
(2015)
This thesis focuses on the directional estimate of the underwater acoustic channel using
modal beamforming with an orthogonal frequency division multiplexed (OFDM)
communication system. An underwater channel model and ...
