(University of Waterloo, 2004)Membrane proteins are involved in vital cellular functions and have important implications in disease processes, drug design and therapy. However, it is difficult to obtain diffraction quality crystals to study transmembrane ... -
Use of Kinematics to Minimize Construction Workers' Risk of Musculoskeletal Injury
(University of Waterloo, 2017-03-29)Construction work requires more repetitive and highly physical effort than, for example, office work. Despite technological advancements in construction, the human factor is still an essential part of the industry. Hence, ... -
The Use Of Kullback-Leibler Divergence In Opinion Retrieval
(University of Waterloo, 2008-10-01)With the huge amount of subjective contents in on-line documents, there is a clear need for an information retrieval system that supports retrieval of documents containing opinions about the topic expressed in a user’s ... -
Use of Liquid Chromatography - Organic Carbon Detection to Characterize Dissolved Organic Matter from a Variety of Environments
(University of Waterloo, 2012-10-26)Dissolved organic matter (DOM) is a heterogeneous mixture of organic compounds comprised mostly of carbon, oxygen, nitrogen, and hydrogen, but is often operationally defined as the concentration of dissolved organic carbon ... -
The use of machine learning algorithms in recommender systems: A systematic review
(Elsevier, 2018-05-01)Recommender systems use algorithms to provide users with product or service recommendations. Recently, these systems have been using machine learning algorithms from the field of artificial intelligence. However, choosing ... -
Use of Markov Decision Process Models in Preventive Medicine
(University of Waterloo, 2018-08-02)The biggest trade-off when proposing health care policies is about balancing the effectiveness and the practicality of the policies. The optimal policies providing benchmark performances can be driven through using operations ... -
Use of Medications for Management of Alzheimer’s Disease in Ontario’s Home Care Population
(University of Waterloo, 2010-04-07)Abstract Background: Home care is an important care setting for those with Alzheimer’s disease (AD). It provides support that allows individuals with AD to remain at home and may delay the transition to long-term care ... -
Use of N2O and its Isotopic Composition to Investigate Nitrogen Processes in Groundwater
(University of Waterloo, 2010-10-01)This study explores the use of N2O and its isotopic composition to investigate nitrogen processes in groundwater aquifers. Groundwater sampling was undertaken in 2008-2009 at two septic system sites (Long Point site and ... -
Use of Non-linear Models Based on Saturation Kinetics to Determine Chronic Co, Se or Zn Toxicity for Either Exposure or Body Burden in Hyalella azteca
(University of Waterloo, 2018-03-26)Water chemistry can influence the bioavailability, and therefore the toxicity, of metals and other elements. Water chemistry measurements have been incorporated into many water guidelines for the concentration of metals ... -
Use of non-orthogonal factor analysis for gauging illusory halo: A technical report
(2022-05-27)Non-orthogonal factor analysis is examined as a possible aid in assessing the extent of illusory halo in survey responses. Data from several studies involving students' evaluation of teaching (SETs) are re-analyzed with ... -
Use of OCT and Oculus Pentacam HR as Aids to Semi-Scleral Contact Lens Fitting
(University of Waterloo, 2013-09-03)Purpose: To determine whether semi-scleral contact lenses (sSCL) can be appropriately fitted using corneal sagittal depth measurements, and to determine the impact of fit on visual acuity, effect of time on topographic ... -
The use of plant functional traits to detect changes in urban wetland management regimes within Kitchener, ON
(University of Waterloo, 2019-08-14)Humans have modified their surrounding environment in ways that often lead to changes in ecosystem structure and function. Ecosystem management efforts are necessary to bring back functioning attributes of ecosystems for ... -
