Detecting malicious DNS tunnels via network flow entropy
(2021-12-17)The thesis proposes the concept of "entropy of a flow" to augment flow statistical features for DNS tunnelling detection, specifically DNS over HTTPS traffic. To achieve this, the use of flow exporters, namely Argus, ... -
DETECTING NO-OPINION RESPONSES IN THE CANADIAN LONGITUDINAL STUDY ON AGING (CLSA) DATASET USING UNSUPERVISED METHODS AND ACTIVE LEARNING
(2022-03-30)In open-ended surveys, participant answers that do not give any legitimate answer or opinion to the question being asked are called no-opinion responses. We consider the problem of detection of no-opinion answers in the ... -
Detection and Quantification of an Ecologically Important Marine Pathogen, Paramoeba invadens
(2016-08-22)A pathogenic amoeba, Paramoeba invadens, causes re-current mass mortalities of sea urchins (Strongylocentrotus droebachiensis) in coastal Nova Scotia, with major ecological consequences for the structure of the rocky ... -
Detection and Removal of Microplastics in Water Treatment: a Laboratory Evaluation
(2023-05-10)Plastic production has significantly increased over the past 50 years due to its low cost, ease of production, versatility, and durability. Plastic materials take decades to degrade and could remain in the environment ... -
Detection and thermal degradation of paralytic shellfish poisoning toxins.

DETECTION OF DDOS ATTACKS BASED ON DENSE NEURAL NETWORKS, AUTOENCODERS AND PEARSON CORRELATION COEFFICIENT
(2020-04-16)Distributed Denial of Service (DDoS) is a set of frequent cyber attacks used against public servers. Because DDoS attacks can be launched remotely and reflected by legit- imated users on networks, it is hard for victims ... -
Detection of Endoplasmic Reticulum Stress and Progression of Steatohepatitis in Mink (Neovison vison) with Fatty Liver
(2011-09-06)This study used the non-alcoholic steatohepatitis activity index (NAI), presence of fibrosis and Mallory-Denk bodies (MDBs), and quantification of glucose regulated protein 78 (GRP78) messenger ribonucleic acid (mRNA) ... -
Detection of Ovulation in Dairy Cows by Twice-Daily Passive Monitoring of Reticulo-Rumen Temperature
(2012-12-19)The objective of this study was to determine the ability of a passive temperature monitoring system consisting of radio frequency identification (RFID) boluses with thermistors and receiver panels to detect ovulation in ... -
DETECTION OF UDP FLOOD ATTACKS IN WIRELESS SENSOR NETWORKS BY VISUALIZATION ON PARALLEL COORDINATE PLOT
(2021-03-10)Distributed Denial of Service (DDoS) attacks are one of the most destructive attacks that threaten network systems’ security today. In this type of attack, the attacker tries to make a targeted computer or network unreachable ... -
THE DETERMINANTS OF ADULT PARTICIPATION IN JOB-RELATED EDUCATION/TRAINING IN CANADA: WHO GETS ACCESS?
(2011-12-16)In this thesis, we explore determinants of Canadian workers’ job-related education and training take-ups by using the 2008 Access and Support to Education and Training Survey (ASETS). We implement three models, OLS, probit ... -
The Determinants of Greenhouse Gas Emissions: Empirical Evidence From Canadian Provinces
(2021-12-03)The main objective of the present study is to examine the determinants of greenhouse gas emissions in Canada using panel data of 10 provinces from 1990 to 2019. The pooled ordinary least squares method is used to estimate ... -
The Determinants of Health Care Costs in Older Adults Undergoing Non-Elective Abdominal Surgery
(2013-10-24)Health care spending in Canada has been increasing faster than the rate of gross domestic product (GDP). A disproportionate amount of the health care spending is allocated to care of older adults. Non-elective abdominal ... -
DETERMINANTS OF THE BIODIVERSITY AND COMPOSITION OF STREAM INSECT COMMUNITIES
(Springer, 2009)The North Mountain of the Annapolis Valley, NS, in eastern Canada, is a ~200 km basalt ridge drained by many small first or second order streams in independent catchments. The area is fairly uniform geologically, presenting ... -
DETERMINATION OF CAPILLARY PRESSURE, RELATIVE PERMEABILITY AND PORES SIZE DISTRIBUTION CHARACTERISTICS OF COAL FROM SYDNEY BASIN-CANADA
(2012-08-28)Global warming due to anthropogenic emission of greenhouse gases notably carbon dioxide, could lead to the irreversible melting of the polar ice and significant increases in global mean temperature. One of the mitigating ... -
DETERMINATION OF EPOXIDES AND ALCOHOLS IN EDIBLE OILS
(2017-09-01)Lipid oxidation refers to the oxidative degradation of lipids, leading to toxicity and rancid flavours of lipid-containing foods. This process is often measured by determining hydroperoxides and their breakdown products, ... -
Determination of Failure Criteria for Suspended Ceiling Tile Systems and Thermal Resistance Provided Prior to Failure
(2022-04-25)The use of suspended ceiling tile systems has become popular in modern construction; however, fire performance data for these systems has not followed this trend. There currently is a lack of credible fire performance test ... -
DETERMINATION OF PROTON RADII OF NEUTRON-RICH OXYGEN ISOTOPES FROM CHARGE-CHANGING CROSS SECTION MEASUREMENTS
(2018-08-21)The nuclear charge radius is an important bulk property of the nucleus for investigating nuclear structure. The nuclei lying close to the boundaries of the nuclear chart (the drip lines) have revealed new exotic features ... -
Determination of Soil and Plant Nutrient Sufficiency Levels for Haskap (Lonicera caerulea L.)
(2018-05-03)Balanced nutrition is crucial for haskap (Lonicera caerulea L.) growth, productivity, and economically viable commercial production. However, there are no clearly established soil fertility and leaf tissue nutrient sufficiency ... -
Determination of the Effect of Nutrient Management Plans on Nitrate Concentrations in the Soil and Water Below the Root Zone in Commercial Potato Production.
(2011-04-15)Nitrate leaching from research and commercial potato rotations was evaluated using stainless steel zero tension lysimeters, tile drainage and soil samples. The effect of nutrient management versus conventional fertility ... -
