Characterization of Off-Body Area Network Channels During Walking
(Journal article; Peer reviewed, 2019)In this work, the off-body area network channel characteristics during walking were investigated using finite difference time-domain. The channels were investigated in terms of fade variation and the correlation between ... -
Characterization of the Body-to-Body Propagation Channel for Subjects during Sports Activities
(Journal article; Peer reviewed, 2018)Body-to-body wireless networks (BBWNs) have great potential to find applications in team sports activities among others. However, successful design of such systems requires great understanding of the communication channel ... -
A Class-Imbalanced Heterogeneous Federated Learning Model for Detecting Icing on Wind Turbine Blades
(Peer reviewed; Journal article, 2022)Wind farms are typically located at high latitudes, resulting in a high risk of blade icing. Data-driven approaches offer promising solutions for blade icing detection, but they rely on a considerable amount of data. Data ... -
Cohesive-zone models and singularities at corners and cracks in homogeneous materials
(Peer reviewed; Journal article, 2022)The stress singularities at corners in elastic bodies are not strong enough to provide a driving force for fracture, except in the limit of a crack. Here, we re-examine these elastic stresses from the perspective of ... -
A Collaborative Beetle Antennae Search Algorithm Using Memory Based Adaptive Learning
(Peer reviewed; Journal article, 2021)Recently developed Beetle Antennae Search algorithm (BAS) mimics the odor sensing mechanism of the longhorn beetles. The beetles have many species and many of these are advantageous to the nature as well as the mankind. ... -
Collaborative Fault Diagnosis Decision Fusion Algorithm Based on Improved DS Evidence Theory
(Chapter, 2020)DS evidence theory has in obtaining a correct diagnosis when confronted with highly conflicting evidence, a collaborative fault diagnosis decision fusion algorithm based on an improved version of DS evidence theory is ... -
Color appearance in rotational material jetting
(Peer reviewed; Journal article, 2022)Material jetting (MJT) is a recognized additive manufacturing (AM) method to combine various materials and create a wide range of designed appearances. However, the measured color of MJT objects is frequently different ... -
A combined analysis of the drying and decomposition kinetics of wood pyrolysis using non-isothermal thermogravimetric methods
