Megacities and tall buildings: symbiosis

E3S Web of Conferences, 2018
Anyone concerned with the development of human civilization in the 21st Century will likely have heard the term «megacity». It is – as it should be – increasingly prevalent in both mainstream and academic discussions of the great trends of our time ...

VAE+DDPG: An Attention‐Enhanced Variational Autoencoder for Deep Reinforcement Learning‐Based Autonomous Navigation in Low‐Light Environments

Advanced Intelligent Systems, EarlyView.
Variational Autoencoder+Deep Deterministic Policy Gradient addresses low‐light failures of infrared depth sensing for indoor robot navigation. Stage 1 pretrains an attention‐enhanced Variational Autoencoder (Convolutional Block Attention Module+Feature Pyramid Network) to map dark depth frames to a well‐lit reconstruction, yielding a 128‐D latent code ...

Evaluating the African arid corridor hypothesis: A meta‐analysis including the phylogenetic and biogeographical history of Sesamothamnus

American Journal of Botany, EarlyView.
Abstract Premise We examined the African arid corridor (AAC) disjunction pattern of vascular plants between northeastern and southwestern Africa in the context of geological and climatic events since the late Miocene. We developed a phylogenetic and biogeographical framework for the arid‐adapted genus Sesamothamnus (Pedaliaceae), a classic example of ...

Wind-Induced Aerodynamic Effects on Set-Back Tall Buildings Using LES

Buildings
Set-back modification represents a dependable method to reducing the wind effects on high-rise buildings, but the flow mechanism and aerodynamic responses of set-back tall buildings have not been explored systematically.

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

American Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

Methane Pyrolysis Performance in Catalytic Molten Media for Hydrogen Production From the Perspective of Bubble Column Reactor Design and Configuration

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In the hydrogen production routes from natural gas (methane), methane pyrolysis offers a cleaner option than the established steam methane reforming by producing CO2‐free hydrogen. However, in fixed bed reactors over solid catalysts, this technology experiences rapid catalyst deactivation due to carbon (coke) deposition encapsulating its ...

The Role of Tall Buildings in Sustainable Urban Composition—The Case of Hanza Tower in Szczecin (Poland)

Arts
Tall buildings are a unique category of architectural objects, as they are characterized by a strong self-presentation effect and have a significant visual impact on the urban composition and the surrounding cityscape.

Early Pliocene Varanus (Squamata, Varanidae) remains from Megalo Emvolon, Thessaloniki, Greece

The Anatomical Record, EarlyView.
The article describes new cranial and postcranial varanid material from Megalo Emvolon Lower Pliocene vertebrate fossil site near Thessaloniki. The fossils, likely representing a single individual, are referred to Varanus cf. marathonensis. Abstract This study describes new fossil varanid material from a recently discovered fossil spot (MVL site) at ...

Effect of Structural Forms on Wind-Induced Response of Tall Buildings: A Finite Element Approach

Eng
Tall buildings are vulnerable to wind loads, which can cause significant displacements that can affect their stability, strength, and serviceability. Their structural configuration can significantly influence their behavior to wind loads.
