Anthropology of a city: organization, communication, information [PDF]

open access: yesВестник археологии, антропологии и этнографии, 2020
The article is concerned with the anthropology of a city. As an instrument of conceptualization, we used a three-dimensional scheme: organization — communication — information, which allows giving the urban interpretation for each of the coordinates, and

Effects of Orientations, Aspect Ratios, Pavement Materials and Vegetation Elements on Thermal Stress inside Typical Urban Canyons [PDF]

open access: yes, 2019
The analysis of local climate conditions to test artificial urban boundaries and related climate hazards through modelling tools should become a common practice to inform public authorities about the benefits of planning alternatives. Different finishing

Switchable Supramolecular Adhesive by Tuning Interfacial Bonding and Modulus

open access: yesAdvanced Functional Materials, EarlyView.
The supramolecular adhesive (HyDiP) shows reversible adhesion and recyclability. In the dehydrated state, it is dense, stiff (E ≈445 MPa), transparent, and provides strong bonding with adhesion strengths up to 4.65 MPa. In the hydrated state, it becomes porous, soft (E ≈0.11 MPa), and detaches easily, enabling sustainable high‐strength applications ...

A model to optimize the location and size of facilities based on the area of the facility and the visit time of users

open access: yesJapan Architectural Review, 2023
This paper proposes a new model to optimize the location and size of facilities that serve the public. The objective function is based on the floor area of the facility and the time that individuals spend in the facility.

Sustainable Transport in a Compact City [PDF]

open access: yes, 2010
Transport policies in many countries seek to achieve a modal shift from the private car to public transport, in order to reduce environmental externalities like (local) air pollution, stench and visual annoyance, congestion etc. At the same time, the relationship between the spatial organisation and transportation is widely acknowledged, because the ...

MAGTWIST: A Magnetically‐Driven Rotary Actuator Using a Traveling‐Wave With Integrated Stiffness Tunability

open access: yesAdvanced Functional Materials, EarlyView.
MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.

Strategies for Sustainable Urban Development and Urban-Rural Linkages

open access: yesEuropean Journal of Spatial Development, 2014
An important driving force behind urban expansion is the growth of the urban population. But for Europe, this is not a sufficient explanation. The major trend is that European cities have become much less compact.

Mapping Europe into local climate zones [PDF]

open access: yes, 2019
Cities are major drivers of environmental change at all scales and are especially at risk from the ensuing effects, which include poor air quality, flooding and heat waves.

Molecularly Engineered Highly Stable Memristors with Ultra‐Low Operational Voltage: Integrating Synthetic DNA with Quasi‐2D Perovskites

open access: yesAdvanced Functional Materials, EarlyView.
Molecularly engineered memristors integrating Ag nanoparticle–embedded synthetic DNA with quasi‐2D halide perovskites enable ultra‐low‐operational voltage, forming‐free resistive switching, and record‐low power density. This synergistic integration of customized DNA and 2D OHP in bio‐hybrid architecture enhances charge transport, reduces variability ...

Capacity of Urban Green Infrastructure Spaces to Ameliorate Heat Wave Impacts in Mediterranean Compact Cities: Case Study of Granada (South-Eastern Spain)

open access: yesLand, 2023
Heat wave episodes are becoming more frequent and severe worldwide, especially in areas such as the Mediterranean region. This study is aimed at assessing the impact of heat waves in an urban environment and the ways areas of urban green infrastructure ...
