Can the Hubble tension be resolved by bulk viscosity?
(Journal article; Peer reviewed, 2021)We show that the cosmic bulk viscosity estimated in our previous works is sufficient to bridge the H0 value inferred from observations of the early universe with the value inferred from the local (late) universe. -
A Cascaded Heading Control Design With Motion Constraint Handling for Marine Surface Vessels
(Journal article, 2023)Maritime motion control systems traditionally employ proportional-integral-derivative (PID) feedback control combined with a model-based feedforward structure for heading control. However, such control designs often suffer ... -
A Change-Driven Image Foveation Approach for Tracking Plant Phenology
(Peer reviewed; Journal article, 2020)One of the challenges in remote phenology studies lies in how to efficiently manage large volumes of data obtained as long-term sequences of high-resolution images. A promising approach is known as image foveation, which ... -

Classification and determinants of passing difficulty in soccer: a multivariate approach
(Peer reviewed; Journal article, 2021)Introduction Usually, the players’ or teams’ efficiency to perform passes is measured in terms of accuracy. The degree of difficulty of this action has been overlooked in the literature. Objectives The present study ... -
Classification of Failures in the Perception of Conversational Agents (CAs) and Their Implications on Patient Safety
(Peer reviewed; Journal article, 2021)The use of Conversational agents (CAs) in healthcare is an emerging field. These CAs seem to be effective in accomplishing administrative tasks, e.g. providing locations of care facilities and scheduling appointments. ... -
Cloud-based Smart IoT Sustainable Solution for Waste Sorting and Management
(Chapter, 2022)A neat and clean surrounding is the main driving force for any city to be called a smart city. By 2050, it is expected that 66% of the world population will live in cities. The growing volumes of wastes are largely caused ... -
Co-rotational Reduced Order Kalman Filter Finite Element Method for the Real-time Implementation of Large-scale Structural Models
(Peer reviewed; Journal article, 2023)The real-time implementation of large-scale structural models without sacrificing their physical realism is challenging. This paper introduces a conceptual framework named the Co-rotational Reduced Order Kalman Filter ... -
Co-simulation as a Fundamental Technology for Twin Ships
(Peer reviewed; Journal article, 2020)The concept of digital twins, characterized by the high fidelity with which they mimic their physical counterpart, provide potential benefits for the next generation of advanced ships. It allows analysis of data and ... -
Co-simulation-based Pre-training of a Ship Trajectory Predictor
(Chapter, 2022)A ship trajectory predictor plays a key role in the predictive decision making of intelligent marine transportation. For better prediction performance, the biggest technical challenge is how we incorporate prior knowledge, ... -
