Asphalt surfaces as ecological traps for water-seeking polarotactic insects : How can the polarized light pollution of asphalt surfaces be reduced?

The surface of dry or wet asphalt roads reflects partially linearly polarized light, the degree of linear polarization p of which depends on the darkness and roughness of asphalt: the darker and/or the smoother the asphalt, the higher the p of light reflected from it. If the asphalt is sunlit and the direction of view is parallel to the solar-antisolar meridian, then the direction of polarization

Body composition and migration strategies : a comparison between robins (Erithacus rubecula) from two stop-over sites in Sweden

Robins captured as passage migrants by the Baltic Sea in Sweden at Falsterbo and Ottenby Bird Observatories, respectively, differ with respect to body mass, fat load and orientation behaviour. Relatively more birds with large visual fat deposits are captured at Ottenby than at Falsterbo, but robins at Falsterbo carry more fat than robins at Ottenby. Robins with small fat loads at Ottenby probably

Conditional parametric ARMAX models for observed hourly heat-load dynamics in apartment buildings

This paper presents a methodology for estimation of physically interpretable building energy performance characteristics such as: heat loss coefficient, azimuth angle dependent solar gain, and diurnal periodicity in heat-demand. The models are demonstrated on a case-study with hourly observations of district-heating connected apartment buildings in Denmark. The weather model inputs are obtained fr

Efficient Two-view Estimation using Richer Geometric Correspondences

Two-view estimation is a fundamental problem in 3D computer vision, and an important sub-task of multi-view estimation pipelines such as Structure-from-Motion (SfM) and Simultaneous Localization and Mapping (SLAM). In recent years, the main focus in the field has been on keypoint-based methods, where interest points are first detected and matched across the two images, followed by robust estimatio

Probabilistic and AI-based Methods for Moisture-safe and Sustainable Building Envelope Design

The increasing demand for energy-efficient and sustainable construction necessitates the need for building envelope designs that effectively balance moisture safety with sustainability. Improper moisture management in building envelopes can lead to severe consequences, including construction damage, decreased energy performance, and health risks associated with microbial growth. For instance, wate

Descartes "onda demon" och kristen livskonst

René Descartes’ Meditations on First Philosophy explores foundational philosophical and theological questions through a method of radical skepticism. Central to this exploration is the concept of the evil demon, a hypothetical being that challenges human capacity to comprehend and perceive reality. Descartes’ meditations are pivotal to the development of rationalist philosophy, bridging epistemolo

Historiska cykler: En jämförelse mellan Ibn Khalduns och Oswald Spenglers teorier om civilisationers uppgång och fall : En studie av de drivande faktorerna bakom civilisationers nedgång i Muqaddimah och Västerlandets undergång

This thesis explores the philosophical and historical perspectives of Ibn Khaldun and Oswald Spengler regarding the cyclical nature of civilizations. By analyzing Ibn Khaldun’s Muqaddimah and his theory of asabiyya (social cohesion), alongside Spengler’s kulturseele (cultural soul) in The Decline of the West, the study examines their respective explanations of the rise and fall of societies. Ibn K

Drawing the Infinite

The presentation brings together two of her recent film installations and a selection of her sculptural works from the past decade. It highlights Barba’s continuous engagement with the representational function of images and language as they are channeled through cinematic apparatuses.For Barba, cinema is a sovereign and speculative instrument that critically questions the singular properties of s

Exhibition Notes

The Exhibition Notes installation includes Blind Volumes (2016/2022), a work that uses steel frames as a support, a kind of stage on which films and kinetic sculptures are displayed. Eight further artworks are choreographed around the gallery, transforming it into a place for experimentation. The gallery thus becomes a space where the constitutive elements of film, celluloid, projector and sound a

Radiant Exposures

In Radiant Exposures the artist introduces an exhibition architecture with two angled walls that steers visitors through the space and also provides a structure in which Barba’s films are screened and the artist’s sculptural works installed in a carefully orchestrated setting. Yet, signaling the importance of both film and sound as major themes in Rosa Barba’s practice, visitors will encounter the

Digital Competencies, Disaster Risk Reduction, and Education : An Introduction to the Digital Competency Framework to Develop Digital Pedagogical Competencies of Educators in Disaster Risk Reduction.

The COVID-19 pandemic was a novel biological hazard that emerged in 2019 and significantly impacted various sectors of society. While sectors such as the economy and health were severely affected, the education sector was no stranger to the grave impact of the pandemic. While the pandemic called for regulations such as lockdowns and social distancing, the education sector was required to shift the

Treatment Related to Urinary Tract Infections Is Associated with Delayed Diagnosis of Urinary Bladder Cancer : A Nationwide Population-based Study

BACKGROUND AND OBJECTIVE: It has been suggested that urinary tract infections (UTIs) are associated with delayed diagnosis of bladder cancer (BC). Our aim was to investigate prediagnostic treatments related to UTI and the relation to BC diagnostic delay, reflected by advanced disease at diagnosis. METHODS: We used data from the BladderBaSe 2.0 with data of treatments related to UTI up to 3 yr befo

Ethics as an enabler and a constraint : Narratives on technology development and artificial intelligence in military affairs through the case of Project Maven

Project Maven is an AI-induced information technology for military applications initiated by the United States Department of Defence (DoD) in 2017 and originally signed on to a civilian contractor, namely Google. However, this initiative raised massive resistance from a substantial amount of Google employees, eventually leading to the contract's annulation. This article uses narrative analysis to

Pillage of the Sea : permanent sculpture in the sea

In Ostend, Rosa Barba presents Pillage of the Sea, 2021, a permanent sculpture. Barba has anchored an outsized cairn on the beach, imitating stones by pouring concrete in textile. The textile makes one think of the form of sandbags, with which Barba creates a type of imaginary barrier against the future rise in the sea level. Each stone symbolizes a city, the fate of which is threatened by climate

Coding for intangible competitive advantage : mapping the distribution and characteristics of software-developing firms in the Swedish economy

Software is at the core of digitalisation and is often claimed to play a central role in innovation and in shaping competition across industries and firms. There are yet few studies of the extent and nature of software development across firms. We employ a unique firm-level survey comprising 3,929 firms across Sweden to analyse the distribution and characteristics of firms that invest in software

Weavers

This original proposal by the artist and filmmaker Rosa Barba is deployed in two spaces of the art center. In the nave, she conceives an in situ project, in connection with the research carried out during her recent residency at the Atelier Calder, located in Saché. The second part of the exhibition takes place in the black gallery and immerses us in a cinematographic space mixing images and sculp

A Novel Bipolar PFC Converter for Battery Charging Application

Power electronic converters are pivotal while designing any charging scheme, regardless of the battery capacity and application. Nowadays, Power Factor Correction (PFC) converters have become popular for various battery charging systems due to their simple configurations. Single-Ended Primary-Inductor Converter (SEPIC) and Cuk PFC converters are preferred over buck-boost converters in this regard
