Learning positioning policies for mobile manipulation operations with deep reinforcement learning
(Springer Nature, 2023)
This work focuses on the operation of picking an object on a table with a mobile manipulator. We use deep reinforcement
learning (DRL) to learn a positioning policy for the robot’s base by considering the reachability ...
Cool Concrete Incorporating Carbonated Periwinkle Shell: A Sustainable Solution for Mitigating Urban Heat Island Effects
(ACS, 2024-01)
The urban heat island effect has become a critical issue in urban areas, intensifying heat-related problems and increasing energy consumption. A sustainable cement formulation that combines ordinary Portland cement (OPC) ...
Sir Orfeo as the Source for the Medieval Romance Topoi of Abduction and Otherworld Rampant within The Hobbit’s Mirkwood
(Taylor & Francis, 2021-08-25)
In view of Jason Fisher’s (2011) principles for a rigorous study of J. R. R. Tolkien’s sources, this paper aims to demonstrate that the relationship between Sir Orfeo (c.1330) and The Hobbit (1937) is of influence and not ...
Failure-Analysis Based Redesign of Furnace Conveyor System Components: A Case Study
(MDPI, 2019-08)
Any manufacturing equipment designed from scratch requires a detailed follow-up of the performance for the first units placed in service during the production ramp-up, so that lessons learned are immediately implemented ...
Comparative assessment of synthetic time series generation approaches in healthcare: leveraging patient metadata for accurate data synthesis
(BMC, 2024)
Background
Synthetic data is an emerging approach for addressing legal and regulatory concerns in biomedical research that deals with personal and clinical data, whether as a single tool or through its combination with ...
Tolkien, Shakespeare, Trees, and The Lord of the Rings
(Taylor & Francis, 2024-04-09)
J. R. R. Tolkien maintained an ambivalent attitude toward William Shakespeare throughout his life. As Tom Shippey succinctly affirms, Tolkien read Shakespeare’s works with both interest and disapproval. Shakespeare’s plays, ...
Genetics of ancestry-specific risk for relapse in acute lymphoblastic leukemia
(Springer Nature, 2017-01-18)
The causes of individual relapses in children with acute lymphoblastic leukemia (ALL) remain incompletely understood. We evaluated the contribution of germline genetic factors to relapse in 2225 children treated on Children's ...
Naphthalene-1,8-dicarboxylate based zinc coordination polymers: a photophysical study
(RSC, 2024)
Herein, we report the synthesis and photoluminescence properties of a new 1,3-dioxo-2-(1H-tetrazol-5-yl)-2,3-dihydro-1H-benzo[de]isoquinoline-6,7-dicarboxylic (H3L) ligand and three coordination polymers (CPs). Compound ...
Cardiac output estimation using ballistocardiography: a feasibility study in healthy subjects
(Nature, 2024)
There is no reliable automated non-invasive solution for monitoring circulation and guiding treatment in prehospital emergency medicine. Cardiac output (CO) monitoring might provide a solution, but CO monitors are not ...
The determination of optimum segmentation parameters using genetic algorithms: Application to different segmentation algorithms and transmission electron microscopy tomography reconstructed volumes
(Wiley, 2023-10)
A method for optimizing an automatic selection of values for parameters that feed segmentation algorithms is proposed. Evolutionary optimization techniques in combination with a fitness function based on a mutual information ...
