The Characteristics of Cultural Tourists who Visit Urban Jewish Heritage Centres: The Case Study of Visitors to the White Stork Synagogue in Wrocław [PDF]

open access: yes, 2016
Since the White Stork Synagogue in Wrocław has been restored, opened to visitors and become a part of the so-called District of the Four Faiths promoted by the city council, both the synagogue and its neighbourhood have become tourist attractions which ...

High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

Framework for the implementation of urban big screens in the public space [PDF]

open access: yes, 2009
In the last decade, big urban screens have appeared in town squares and on building facades across the UK. The use of these screens brings new potentials and challenges for city regulators, artists, architects, urban designers, producers, broadcasters ...

Anti‐Slip Material‐Based Strategies and Approaches

open access: yesAdvanced Materials Technologies, EarlyView.
This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.

The Question of Metropolitan Form: Introduction

open access: yesFootprint, 2009
Posing the concept of ‘metropolitan form’ as a question, as in the call for papers for this issue of Footprint, is an absolute necessity at this stage of development of urbanised areas.

Radiative Cooling by Green(er) Solvents‐Upcycled Polyvinyl Chloride From Drug Blisters Waste

open access: yesAdvanced Optical Materials, EarlyView.
This study explores upcycling poly(vinyl chloride) (PVC) from used pharmaceutical blisters into sustainable radiative cooling materials. Using solvent separation and membrane fabrication, PVC was converted into white membranes paired with aluminum foil.

Ecological sustainability and urban form [PDF]

open access: yes
One controversial idea present in the debate on urban sustainability is that urban sprawl is an ecological stressing problem. We have tested this popular assumption by measuring the ecological footprint of commuting and housing of the 163 municipalities ...

Energy Consumption Optimization in Trajectory Planning for Fuel Cell Hybrid Uavs Based On HMPC

open access: yesAdvanced Robotics Research, EarlyView.
The endurance limitation of multirotor drones is a critical challenge. This study adopts a hybrid power system of fuel cells and lithium‐ion batteries. Using Nondominated Sorting Genetic Algorithm II, it integrates trajectory planning with energy management optimization.

From Plows to Pliers - Urban Homesteading in America [PDF]

open access: yes, 1974
The state homestead exemption is the most widely known form of homesteading and exists in the majority if American jurisdictions. A new form of this plan has been added by many east coast cities that allows families to receive a grant of a home at a ...

Improving the Robustness of Visual Teach‐and‐Repeat Navigation Using Drift Error Correction and Event‐Based Vision for Low‐Light Environments

open access: yesAdvanced Robotics Research, EarlyView.
Visual teach‐and‐repeat (VTR) navigation allows robots to learn and follow routes without building a full metric map. We show that navigation accuracy for VTR can be improved by integrating a topological map with error‐drift correction based on stereo vision.
