Acoustic–Visual Sensor Fusion for Robot Localization in Buried Pipes

Journal of Field Robotics, EarlyView.
ABSTRACT Autonomous, untethered robots require robust localization algorithms to perform tasks such as inspection and monitoring in buried pipes. This task is challenging due to environmental constraints, such as the absence of a global positioning system underground and limited visual perception.

A Polar Topology Network Induces Elastic Stiffening in Ferroelectric Oxide Superlattices

Small, EarlyView.
The periodicity in BiFeO3/SrTiO3 superlattices tunes the system into a dense, elastically constrained polar texture state. This topology‐rich regime reveals a collective mechanical response in which interactions among polar topological defects restrict local deformations, producing a pronounced elastic stiffening.

Wave‐Velocity‐Based Temperature Monitoring Applied to Underground Power Cables in Medium‐Voltage Networks—Discrimination of Individual Cable Temperatures in a Distribution Grid

High Voltage, EarlyView.
ABSTRACT The thermal state of underground power cables can be monitored based on the temperature dependency of the dielectric permittivity of the insulation material. The resulting temperature‐dependent wave velocity is used as a thermometric property. To this end, the signal propagation time along a cable of an injected signal is determined.

Conductivity Analysis and Thermoelectric Behaviour of Larch Standing Trees Under Lightning Currents: Role of Moisture Distribution and Carrier Motion

High Voltage, EarlyView.
ABSTRACT The direct effects of lightning strikes on forest combustibles form the foundation for predicting lightning‐induced forest fires. Accurate assessment of lightning impact is hindered by limited knowledge of the conduction characteristics of standing larch trees.

Orbital reflectometry

, 2010
The occupation of d-orbitals controls the magnitude and anisotropy of the inter-atomic electron transfer in transition metal oxides and hence exerts a key influence on their chemical bonding and physical properties. Atomic-scale modulations of the orbital occupation at surfaces and interfaces are believed to be responsible for massive variations of the

Drought and soil macrofauna functional diversity effects on Mediterranean tree growth in an Ecotron ecosystem experiment

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The intensity, frequency and severity of drought events are projected to increase in the Mediterranean region under ongoing climate change. This may impact plant growth and survival in Mediterranean forests leading to altered ecosystem dynamics. The functional diversity

Using time domain reflectometry in triaxial testing [PDF]

, 2000
: Time domain reflectometry (TDR) can be used to determine the volumetric water content of soils. This note describes the utilization of a TDR miniprobe in triaxial testing. The TDR performance was examined with a series of tests that not only proved its
