A new estimation method for COVID-19 time-varying reproduction number using active cases
Hasan, Agus Ismail; Susanto, Hadi; Tjahjono, Venansius; Kusdiantara, Rudy; Putri, Endah; Nuraini, Nuning; Hadisoemarto, Panji (Peer reviewed; Journal article, 2022)We propose a new method to estimate the time-varying effective (or instantaneous) reproduction number of the novel coronavirus disease (COVID-19). The method is based on a discrete-time stochastic augmented compartmental ... -
A numerical framework for estimating the effective reproduction number of infectious diseases from compartmental epidemic models
Hasan, Agus Ismail (Peer reviewed; Journal article, 2021)We present a numerical framework for estimating the effective reproduction number of infectious diseases from compartmental epidemic models. The idea is to augment the reproduction number as an extended state variable in ... -
Predictive digital twin for offshore wind farms
Haghshenas, Amirashkan; Hasan, Agus Ismail; Osen, Ottar Laurits; Mikalsen, Egil Tennfjord (Peer reviewed; Journal article, 2023)As wind turbines continue to grow in size, they are increasingly being deployed offshore. This causes operation and maintenance of wind turbines becoming more challenging. Digitalization is a key enabling technology to ... -
Temporal Topology Density Map
Hu, Zhicheng; Hojjati, Amirabbas; Haghshenas, Amirashkan; Hasan, Agus Ismail; Da Silva Torres, Ricardo (Peer reviewed; Journal article, 2023)Spatiotemporal data visualization is of paramount importance in several applications, especially for analyzing urban mobility data encoded on topologies. This paper introduces a novel solution, called Temporal Topology ... -
Towards fully autonomous floating offshore wind farm operation & maintenance
Ambarita, Evi Elisa; Karlsen, Anniken Susanne Thoresen; Osen, Ottar Laurits; Hasan, Agus Ismail (Peer reviewed; Journal article, 2023)Wind energy is one of the most versatile and promising sustainable energy solutions. Wind energy can be harvested in both onshore and offshore environments. Due to the environmental and societal impacts of onshore wind ...
