Bird Images on Ceramics Produced in South-Eastern Crimea from the Excavations of Azak

Археология евразийских степей, 2022
The paper considers the 14th century Crimean glazed ceramics with ornithomorphic design made in “sgraffito”, “sgraffito with polychrome coloring” techniques, or a combination of “sgraffito” and “engobe scraping” techniques discovered in the territory of ...

Basic level scene understanding: categories, attributes and structures [PDF]

, 2018
A longstanding goal of computer vision is to build a system that can automatically understand a 3D scene from a single image. This requires extracting semantic concepts and 3D information from 2D images which can depict an enormous variety of ...

Do Wind Turbines Amplify the Effects of Lightning Strikes A Full-Maxwell Modelling Approach [PDF]

, 2022
Wind turbines (WTs) can be seriously damaged by lightning strikes and they can be struck by a significant number of flashes. This should be taken into account when the WT lightning protection system is designed.

Photogrammetric UAV Mapping of Terrain under Dense Coastal Vegetation: An Object-Oriented Classification Ensemble Algorithm for Classification and Terrain Correction

Remote Sensing, 2017
Photogrammetric UAV sees a surge in use for high-resolution mapping, but its use to map terrain under dense vegetation cover remains challenging due to a lack of exposed ground surfaces. This paper presents a novel object-oriented classification ensemble

Lightning strikes to tall objects: A study of wave interactions at the return‐stroke front using a nonlinear transmission line model [PDF]

Journal of Geophysical Research: Atmospheres, 2015
AbstractA theoretical study is presented to investigate lightning strikes to towers, with focus on wave interactions occurring at the return‐stroke front due to the arrival of current pulses that propagate upward on the channel after being transmitted from the tower.

Enhancing Corrosion Resistance and Mechanical Strength of 3D‐Printed Iron Polylactic Acid for Marine Applications via Laser Surface Texturing

Advanced Engineering Materials, EarlyView.
Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Role of vision and mechanoreception in bed bug, Cimex lectularius L. behavior. [PDF]

PLoS ONE, 2015
The role of olfactory cues such as carbon dioxide, pheromones, and kairomones in bed bug, Cimex lectularius L. behavior has been demonstrated. However, the role of vision and mechanoreception in bed bug behavior is poorly understood.

On the use of lumped sources in a nonlinear lightning return stroke model and extension for evaluating strikes to tall objects [PDF]

Journal of Geophysical Research: Atmospheres, 2009
The use of lumped current and voltage sources is investigated in a nonlinear return stroke model that includes the dependence of the channel per‐unit‐length resistance on the lightning current and the variation of the channel impedance with height. First, considering the case of lightning strikes to flat ground, it is shown that equivalent channel ...

Body-part-specific Representations of Semantic Noun Categories. [PDF]

, 2012
Word meaning processing in the brain involves ventrolateral temporal cortex, but a semantic contribution of the dorsal stream, especially frontocentral sensorimotor areas, has been controversial. We here examine brain activation during passive reading of
