Directive Antenna Clutter Loss in Slant Paths

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper investigates the development of a clutter loss model specifically for slant paths involving directive antennas. Conventionally, clutter loss is characterized by using isotropic antennas to facilitate standard link budget calculations via single antenna gain values.

World Models for Robotic Manipulation: A Survey

SmartBot, EarlyView.
World models enable robots to anticipate how candidate actions may alter object configurations, contact states, and scene geometry before physical execution. This survey examines world models for robotic manipulation as action‐conditioned predictive systems and organizes the literature according to predicted representations, interfaces between ...

Task‐Oriented Hierarchical Environment Modeling via Spatial Belonging Relationships for Domestic Service Robots

SmartBot, EarlyView.
Domestic service robots in dynamic homes often rely on memory‐intensive, quickly outdated 3‐D maps. This work presents HEMDSR, a four‐layer, task‐oriented model that reasons about object‐room and object‐object spatial belonging relationships, encodes observation viewpoints, and builds local 3‐D maps just‐in‐time.

AI‐Powered GPR Characterization of Peatland Underground Cavity Induced by Smoldering Wildfire: A Laboratory Proof‐of‐Concept

Safety Science and Technology, EarlyView.
We present an AI‐assisted ground‐penetrating radar framework to noninvasively detect and quantify smoldering wildfire‐induced subsurface cavities in peatlands. A ResNet model accurately predicts cavity geometry from GPR images, enabling improved assessment of underground fire damage and hazards.

Respecifying Stigma and the Language of Relationships: Attributes and Categories as Contexturally‐Achieved Phenomena in the Search for Help

Symbolic Interaction, EarlyView.
This article revisits Goffman's original formulations of stigma. In doing so, the discussion focuses, specifically, upon his emphasis that a “language of relationships, not attributes is needed.” The analysis is intended to demonstrate how Goffman's observations offer a starting point for an inquiry in to just how members produce and orient to “spoiled

Refined Safety Distance Measurement of Heavy Construction Machinery Near Electricity Operation Based on Feature‐Homogenised Spatial Target Analysis

High Voltage, EarlyView.
ABSTRACT Heavy construction machinery is essential for power infrastructure construction and maintenance, making safety distance measurement crucial for ensuring operational safety. Existing methods, which rely on target space mapping, face challenges such as error accumulation and limited accuracy.
