Towards vertical urban geometry extraction: occlusion-reduced estimation from street view images using diffusion models

International Journal of Digital Earth
Understanding urban structure is crucial for analysing city dynamics, urban planning, energy efficiency, and environmental sustainability. Extracting urban vertical geometry, such as building heights, is essential to these efforts. However, as cities are

IM2ELEVATION: Building Height Estimation from Single-View Aerial Imagery

Remote Sensing, 2020
Estimation of the Digital Surface Model (DSM) and building heights from single-view aerial imagery is a challenging inherently ill-posed problem that we address in this paper by resorting to machine learning.

Variable Stiffness Flexure Structures Enabled by Phase‐Change Gallium and Adhesive Interfacial Locking for Soft Robotic Applications

Advanced Engineering Materials, EarlyView.
A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.

Thermodynamic Pathways of Nonequilibrium Solidification in Wire‐Arc Additive Manufacturing Fe‐Based Multicomponent Alloy Structures

Advanced Engineering Materials, EarlyView.
Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Effects of Building Height and Window-to-Wall Ratio on Cooling Demand, Passive Comfort, and Peak Demand in a Composite Climate: EnergyPlus Simulations and an Exploratory Surrogate Model

Buildings
Rapid vertical growth in Tier-2 Indian cities is reshaping residential forms and may affect cooling demand, passive comfort, overheating severity, and peak electricity demand. This study examines the influence of building height and window-to-wall ratio (

Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

Advanced Engineering Materials, EarlyView.
A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Height, Weight, and Body Mass of the British Population Since 1820 [PDF]

The average height of a population has become a familiar measure of that population's nutritional status. This paper extends the use of anthropometric data in the study of history by exploring published evidence on the weight, as well as the height, of ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

Advanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

New generalized expressions for forced convective heat transfer coefficients at building facades and roofs [PDF]

, 2017
Previous research indicated that the surface-averaged forced convective heat transfer coefficient (CHTC) at a windward building facade can vary substantially as a function of building width and height.
