A novel membrane electrode assembly design for proton exchange membrane fuel cells: Characterization and performance evaluation
(Elsevier, 2019-03-10)Conventional membrane-electrode assembly (MEA), a key component in proton exchange membrane fuel cells, only operates reasonably within a narrow range of operating conditions. In this study, a scaled-up MEA that can perform ... -
A novel microfluidic resistive pulse sensor with multiple voltage input channels and a side sensing gate for particle and cell detection
(Elsevier, 2019-04-04)Traditionally, a resistive pulse sensor (also known as Coulter counter) works by letting a particle pass through a small orifice in an electrolyte solution. The detection sensitivity mainly relies on the volume ratio of ... -
A novel micromechanical model of nonlinear compression hysteresis in compliant interfaces of multibody systems
(Springer, 2016-07)A micromechanical model of nonlinear hysteretic compression between interacting bodies of multibody systems, covered with fibrous structures, has been created and validated experimentally in this work. As an application, ... -
A Novel Percutaneous Electrode Implant for Improving Robustness in Advanced Myoelectric Control
(Frontiers Media, 2016-03-31)Despite several decades of research, electrically powered hand and arm prostheses are still controlled with very simple algorithms that process the surface electromyogram (EMG) of remnant muscles to achieve control of one ... -
A novel selective disassembly sequence planning method for adaptive reuse of buildings
(Elsevier, 2018-05-10)Adaptive reuse of buildings can be an attractive alternative to new construction in terms of sustainability and a circular economy. Achieving net benefits with adaptive reuse partly relies on efficiently planning building ... -
A Novel Test Geometry for Characterization of Traction-Separation Behaviour in Composite Laminates Under Mode I Delamination
(Springer, 2021-04-16)The integration of composite laminates into automotive structures can provide weight reduction and improvement in occupant safety. However, the adoption of such materials requires characterization and efficient modeling ... -
Novelty Detection in Airport Baggage Conveyor Gear-Motors Using Synchro-Squeezing Transform and Self-Organizing Maps
(Prognostic and Health Management Society, 2013)A powerful continuous wavelet transform based signal processing tool named Synchro-squeezing transform (SST) has recently emerged in the context of non-stationary signal processing. Founded upon the premise of time-frequency ... -
An Npz Model With State-Dependent Delay Due To Size-Structure In Juvenile Zooplankton
(Society for Industrial and Applied Mathematics, 2016)The study of planktonic ecosystems is important as they make up the bottom trophic levels of aquatic food webs. We study a closed nutrient-phytoplankton-zooplankton (NPZ) model that includes size structure in the juvenile ... -
Nucleotide coordination with 14 lanthanides studied by isothermal titration calorimetry
(Elsevier, 2017-06-09)With their hydrolytic, optical and magnetic properties, lanthanide ions (Ln3+) are versatile probes for nucleic acids. In addition, nucleotide-coordinated Ln3+ ions form useful nanoparticles. However, the thermodynamic ... -
Number of prime factors with a given multiplicity
(Cambridge University Press, 2022-03)Let k ⩾ 1 be a natural number and ωk (n) denote the number of distinct prime factors of a natural number n with multiplicity k. We estimate the first and second moments of the functions ωk with k ⩾ 1. Moreover, we prove ... -
The number of valid factorizations of Fibonacci prefixes
(Elsevier, 2019-07-05)We establish several recurrence relations and an explicit formula for , the number of factorizations of the length-n prefix of the Fibonacci word into a (not necessarily strictly) decreasing sequence of standard Fibonacci ... -

Numeric and Traffic Light Calorie Labels on Cafeteria Menus: Noticing, Use, and Perceptions Among Young Adults
(Oxford, 2020-05-29)Objectives The objective of this study was to examine the impact of numeric versus interpretive calorie labelling on consumer noticing, use, and perceptions of labels. We hypothesized that due to their at-a-glance format, ... -
Numerical Analysis of Convective Heat Transfer in Fenestration with Between-the-Glass Louvered Shades
(Elsevier, 2009-10)A two-dimensional steady laminar natural convection model of a window cavity with between-panes louvers (i.e., slats) was developed by approximating the system as a vertical cavity with isothermal walls at different ... -
Numerical considerations for the simulation of proppant transport through fractures
(Elsevier, 2019-09)Injection of a proppant slurry (fluid mixed with granular material) into a reservoir to keep fractures open is a common procedure in hydraulic fracturing treatments. This article presents the numerical methodology for ... -
