Polyphenols and saponins – properties and application in cosmetics
No full textThe cosmetics market is an extremely dynamic, developing branch of the industry. There is a constant need for multifunctional ingredients that will meet the growing expectations of consumers. Active ingredients of natural origin are also appreciated more and more often. One of the most commonly used plant extracts are those rich in polyphenols. These ingredients are known for their antioxidant properties, but they can have many more functions in relation to human skin. They act against wrinkles, brighten skin, support protection against harmful UV rays, etc. Other interesting active plant ingredients are saponins – compounds with an amphiphilic structure – that can be natural alternative to surfactants or emulsifiers. They possess antimicrobial activity and strengthen blood vessels. This article briefly characterizes polyphenols and saponins, taking into account their structure and classification, as well as indicates and describes their properties that can be used in the cosmetics industry
Historic structure and cultural consciousness: The space regeneration of Jinling Machinery Manufacturing Bureau, China
No full textDifferent forms of historic structures within the city show diverse cultural and social factors that not only shape the urban personality, but also construct the complexity of historical and modern spaces. Therefore, as far as urban renewal is concerned, on the one hand, it is essential to protect historic structures to stimulate cultural consciousness of spatial intervention in order to preserve the urban personality and on the other hand, it is necessary to reuse historic structures to keep the possibilities of a continuous dialogue between the past, the present and the future of the city. Through the methods of historical analysis and empirical research, this paper takes the renewal of Jinling Machinery Manufacturing Bureau (JMMB), the modern industrial site, as a case to analyze the relationship between historic structures, cultural consciousness and urban development on two scales -urban areas and plot. The research shows that: 1) the continuation of a stable historic structure is the key to maintain cultural identity in the process of space regeneration; 2) the historic structure contains tangible space forms and historical narrative logic; 3) the cultural consciousness determines the value orientation of space regeneration; and 4) the new functions match culture themes that can promote social values of space regeneration

A Quantitative Analysis of the Exoadaptivity of Buildings in London
No full textAdapting cities is a method of addressing global warming and rising sea levels. Rooftop housing, a way of externally
adapting buildings, has recently been promoted in London. The concept of ‘exoadaptivity’ has been developed by this study
to describe how buildings and built environments externally adapt. Using unstructured data from the planning system and text
mining, this study provides a quantitative analysis of the exoadaptivity of buildings in London with an emphasis on the spatial
and temporal dimensions of rooftop housing. The results reveal that the exoadaptivity of buildings in London varied. This
study also finds that there are contrasts in terms of how residential and non-residential buildings adapted. Amidst global
environmental crises such as climate change, exoadapting buildings could be critical to achieving sustainability in the built
environment
Political reform and the form of the city – Reading through the adoption of modern planning in Tehran using space syntax
No full textWith the discovery of abundant oil resources and the bold agenda of the former monarch of Iran, a rigid and ambitious political reform was introduced in the country. Adopting a western way of economic development, these political reforms sought to not only change the social arrangement in the country but also change the way the country was looked upon. This set path for a series of radical and quick changes in the way everyday life of the city dwellers was facing.
Given the importance of the industrialization in these political reforms and moving away from a labour-intensive economy, top-down modern master-planning changed the way the cities were thought of and in turn the way they meant to be serving the political agenda. In time for the rise of the modern methods of material production and vehicular-based strategic planning, the capital city of Tehran became the most prominent subject to these changes in terms of patterns of development and settlement schemes.
Through a conversation between the planning and policy-making documents and a quantitative analysis of the built city, this research seeks to ask how the change in the political agenda and the approach in city making logic shapes the modern metropolitan area of Tehran and what are the fundamental differences between the process of growth in the built environment before and after the implementation of these changes. The analysis here shows that the fundamental change in the city of Tehran happened after the WWII that a series of development policies changed the logic of city making, and in turn the way the city grew and functioned afterwards
Semantic Segmentation for Autonomous Drone Delivery SUADD’23 Challenge
No full textThe popularity of drones as well as other different flying devices
remains undeterred for several years now, with various industries recognizing
their usefulness in a range of applications. However, the effectiveness
of such systems is heavily dependent on real-time autonomous surface identification.
The goal of this work is to evaluate recently published dataset
dedicated to Unmanned Aircraft Systems. We performed experiments using
several semantic segmentation neural network architectures. We outline possible
improvements for future research and promising results for attentionbased
solutions in the field
Dancing on the peripheries: Performative architecture and cultural diversity in the city of Barcelona today
No full textThe relationship between architecture and ritualized performance is intimate and complex. New cognitive science and ecological psychology understandings of the body-mind-environment connection and role of the body and senses in meaning-making have influenced interdisciplinary dialogue, with the concept of performative architecture explored through fields such as phenomenology, geography, and performance studies. This paper studies the relationship between space, ritual, and event, in performances by ethnic minority communities in Barcelona, examining the phenomenon of regularly occurring dance sessions by resident groups of Filipino and other cultures, in semi-public outdoor spaces throughout the city.
Although the choice of these spaces may appear arbitrary, they are in fact carefully considered by users in terms of their physical and social affordances. The methodology used to uncover common factors among the studied spaces includes analysis through the lens of enactive-embodied cognition and perceptual affordance theory, ethnographic study, and observation based on site visits. The aim is to gain a better understanding of why certain spaces lend themselves to specific actions and ritual events, how peripheral urban spaces can support self-organizing performative actions and creative cultural expression and play, and how architecture and urban form can ‘perform’ cultural diversity in the city. The outcome, in the last instance, is a reinterpretation of the history of old cities from an innovative dialogical perspective that can help build a new sense of place for co-living
Spotting Advertisements from Above: Billboard Detection and Segmentation in UAV Imagery
No full textIn this work, deep-learning methods were researched for billboard
detection in urban environments. Billboards are one of the adversarial
visual pollutants occurring in cities, causing over-saturation of visual stimulation.
Due to this, we develop an algorithm that helps in the analysis and
management of urban space. We utilise near real-time object detection methods
to detect and segment them on images registered by unmanned aerial
vehicles (UAVs). Research is based on recent algorithms from the YOLO
family with modified heads for the instance segmentation task. We gathered
images and prepared hand-annotated labels for training and evaluation purposes
of deep learning approaches. We reached the [email protected] metric of 0.61
for detection and 0.60 for segmentation, enabling us to develop smart city
applications
