Uneven temperature and voltage distributions due to rapid discharge rates and different boundary conditions for series-connected LiFePO4 batteries
(Elsevier, 2017-02-01)This paper presents the surface temperature and voltage distributions on a prismatic lithium-ion battery pack at 1C, 2C, 3C, and 4C discharge rates and 5°C, 15°C, 25°C, and 35°C boundary conditions (BCs) for water cooling ... -
A Unified Simplicial Model for Mixed-Dimensional and Non-Manifold Deformable Elastic Objects
(ACM, 2019-07)We present a unified method to simulate deformable elastic bodies consisting of mixed-dimensional components represented with potentially non-manifold simplicial meshes. Building on well-known simplicial rod, shell, and ... -
Universal bounds for positive matrix semigroups
(Polish Academy of Sciences, 2016)We show that any compact semigroup of positive n×n matrices is similar (via a positive diagonal similarity) to a semigroup bounded by n√. We give examples to show this bound is best possible. We also consider the effect ... -
Universal formula for the holographic speed of sound
(Elsevier, 2018-06-10)We consider planar hairy black holes in five dimensions with a real scalar field in the Breitenlohner–Freedman window and derive a universal formula for the holographic speed of sound for any mixed boundary conditions of ... -
Unlocking the Power of GWF Research: Introducing an AI-Driven Portal for Enhanced Accessibility and User-Friendly Experience!
(University of Waterloo, 2023-05)The Canada First Research Excellence Fund provided CDN $77.8 million to the Global Water Futures Programme (GWF) to generate practical scientific knowledge on how to forecast, prepare for, and manage water futures in Canada, ... -
Unmasking the linear behaviour of slow motor adaptation to prolonged convergence
(Wiley, 2016-06)Adaptation to changing environmental demands is central to maintaining optimal motor system function. Current theories suggest that adaptation in both the skeletal-motor and oculomotor systems involves a combination of ... -
The Unobserved Waiting Customer Approximation
(Springer, 2021-06-02)We introduce a new approximation procedure to improve the accuracy of matrix analytic methods when using truncated queueing models to analyse infinite buffer systems. This is accomplished through emulating the presence of ... -
Unprofitable Affiliates and Income Shifting Behavior
(American Accounting Association, 2017-05)Income shifting from high-tax to low-tax jurisdictions is considered a primary method of reducing worldwide tax burdens of multinational firms. Current losses also affect income shifting incentives. We extend prior approaches ... -
Unravelling the factors that drive separation in differential mobility spectrometry: A case study of regioisomeric phosphatidylcholine adducts
(Elsevier, 2019-10)Differential mobility spectrometry (DMS) has shown promise as an analytical tool in the field of lipidomics. However, the underlying mechanism that drives DMS-based lipid separations is still somewhat unclear. Here, we ... -
Unrestricted State Complexity Of Binary Operations On Regular And Ideal Languages
(Institut für Informatik, 2017-08-27)We study the state complexity of binary operations on regular languages over different alphabets. It is known that if L′m and Ln are languages of state complexities m and n, respectively, and restricted to the same alphabet, ... -
The Unrestricted Variant of Waring's Problem in Function Fields
(Adam Mickiewicz University, 2007-09)Let J k q [t] denote the additive closure of the set of k th powers in the polynomial ring Fq[t], defined over the finite field Fq having q elements. We show that when s>k + 1 and q>k 2k+2 , then every polynomial in ... -
Upflow anaerobic-microaerobic fixed biofilm reactor integrating methanogenesis with partial nitrification
(Elsevier, 2018-09-15)An anaerobic-microaerobic fixed biofilm (AMFB) reactor, that integrates methanogenesis with partial nitrification within a single unit was investigated to achieve carbon removal simultaneously with ammonium oxidation in ... -
Uranium and molybdenum isotope evidence for an episode of widespread ocean oxygenation during the late Ediacaran Period
(Elsevier, 2015-05-01)To improve estimates of the extent of ocean oxygenation during the late Ediacaran Period, we measured the U and Mo isotope compositions of euxinic (anoxic and sulfidic) organic-rich mudrocks (ORM) of Member IV, upper ... -
Uranium isotope compositions of mid-Proterozoic black shales: Evidence for an episode of increased ocean oxygenation at 1.36Ga and evaluation of the effect of post-depositional hydrothermal fluid flow
(Elsevier, 2017-09-01)We report U isotope data for marine black shales of the early Mesoproterozoic Velkerri Formation (Roper Group) and late Paleoproterozoic Wollogorang Formation (Tawallah Group) from the McArthur Basin, Northern Australia. ... -
URBAN PHOSPHORUS SPECIATION AND EXPORT LOADS: A PAIRED SEWERSHED FIELD AND MODELING STUDY
(University of Waterloo, 2023-05-14)In this study, annual and seasonal loads of phosphorus (P) exported from two neighbouring urban sewersheds (AJE and AJW) discharging into Lake Ontario were estimated. The following different chemical pools of P were ... -
Usage of Interactive Event Timelines in Collaborative Digital Tabletops with Automation
(Springer, 2016)Tabletop computers are increasingly being used for complex scenarios, such as emergency response. In such scenarios, maintaining situation awareness of dynamic changes automated by the system is crucial for users to make ... -
Usage of Interface Management System in Adaptive Reuse of Buildings
(MDPI, 2019-05)Adaptive reuse of buildings is considered a superior alternative for new construction in terms of sustainability and a disruptive practice in the current capital project delivery model for the renewal of today’s built ... -
