Design, Modeling, and Experimentation of Polar Robot: Assisted Sail and Multimode Motion for Energy Saving

open access: yesAdvanced Intelligent Systems, EarlyView.
This article proposes a polar robot that utilizes assisted sail and multimode motion to achieve energy‐saving. The design, modeling, and experimental methods are introduced. The results show that the energy‐saving effect of the robot using a multimode energy savings control strategy reaches 21.19%, providing technical support for long‐term polar ...

Exploiting Multitask Deep Learning to Identify Multiple Heavy Metal Contamination at Large Scales

open access: yesAdvanced Intelligent Systems, EarlyView.
A multitask deep learning framework evaluates manganese, chromium, and cobalt concentrations in European soils, achieving an average R2 of 0.75. From 2009 to 2015, soil concentrations increase significantly. Source analysis identifies anthropogenic manganese and geological chromium and cobalt origins.

Effects of Fire and Explosion Event in a Rural Area Fuel Depot Tank Farm: A Case Study From Istanbul, Türkiye

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Chemical facilities storing large volumes of flammable liquids close to residential areas pose severe fire‐and‐explosion hazards that can escalate into disasters. In this study, a tank farm located within Istanbul's city limits is examined to evaluate possible catastrophic scenarios using consequence analysis methods. For this purpose, several

Commentary: The missing sabertooth baculum—At what point might the absence of evidence reasonably be considered evidence of absence?

open access: yesThe Anatomical Record, EarlyView.
Abstract Most carnivorans and all modern felids have ossified bacula; however, no machairodont baculum has ever been identified. This is true despite the many fairly complete skeletons found around the world of several sabertooth taxa. Although the bacula of modern felids are much smaller than those of canoids (even the least weasel's baculum is longer

Surface deformation induced by the 2016 Meinong earthquake and its implications to active folds

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2023
We present 230 field observations on the location, trending, and displacement vectors of the coseismic surface cracks induced by the 2016 Meinong earthquake in the Guanmiao area, SW Taiwan. Coseismic surface cracks trends from the north to northeast. The

A comparison of Landsat 8 (OLI) and Landsat 7 (ETM+) in mapping geology and visualising lineaments: A case study of central region Kenya

open access: yes, 2015
Availability of multispectral remote sensing data cheaply and its higher spectral resolution compared to remote sensing data with higher spatial resolution has proved valuable for geological mapping exploitation and mineral mapping.

Functional models from limited data: A parametric and multimodal approach to anatomy and 3D kinematics of feeding in basking sharks (Cetorhinus maximus)

open access: yesThe Anatomical Record, EarlyView.
Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.
