Advancing Cave Survey Methods: High‐Precision Mapping in Drakotrypa Cave, Greece

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Cave floor mapping plays a vital role across various scientific disciplines by enabling the identification and interpretation of features shaped by both natural processes and human activity. In cave archaeology, floor mapping is crucial to decode and reconstruct human‐induced morphological features.

Ultrasonic surface post-processing of hot isostatic pressed and heat treated superalloy parts manufactured by laser powder bed fusion

open access: yesAdditive Manufacturing Letters, 2022
Inconel 718 alloy parts were fabricated by the laser powder bed fusion (L-PBF) technique using a multidirectional stripe scanning strategy. Subsequently, the L-PBF-built parts were hot isostatic pressed (HIP), homogenized, and aged.

Surface initial characteristics and rainfall influence on fractal dimension of soil microrelief [PDF]

open access: yes, 1998
[Abstract] The complex behavior of soil surface microrelief and its evolution is difficult to quantify. Several empirical roughness indices and geostatistical procedures currently used have been found to be sensitive to describe roughness differences ...

Effects of rock fragments on physical degradation of cultivated soils by rainfall [PDF]

open access: yes, 1995
To understand better the role of rock fragments in soil and water conservation processes, the effects of rock fragments in maintaining a favourable soil structure and thus also in preventing physical degradation of tilled soils was studied.

Cutting Through the Green: A Case for Grassland Archaeology Using UAV Multispectral Data

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Advances in low‐altitude remote sensing are needed to improve the effectiveness of archaeological prospection in the Netherlands. The geomorphological situation and land use history make applying various remote sensing and geophysical technologies particularly challenging.

Tillage-induced spatial distribution of surface crusts on a sandy paleustult from Togo [PDF]

open access: yes, 1996
The spatial distribution of crusts in coarse-textured soils and the processes affecting it are poorly documented, despite the potential impact of crusts on water infiltration.

Threshold Currents of Vacuum Arcs With Tungsten and Copper Cathodes

open access: yesHigh Voltage, EarlyView.
ABSTRACT This paper presents the results of an experimental study aimed at determining the threshold current for triggering a vacuum arc discharge, the probability of arc ignition and the average arc operation time depending on the current for tungsten and copper electrodes.

Creating Microrelief on the Inner Surface of the Cylinder Liner By Laser Radiation [PDF]

open access: yes, 2015
Определены с точки зрения максимизации гидродинамической несущей способности шаговысотные параметры микрорельефа, которые могут обеспечить минимальную, но достаточную ширину зазора в сопряжениях цилиндропоршневой группы для обеспечения жидкостного трения.
