Latest generations of district heating and cooling systems are characterised by low network temperature with uninsulated pipes, decentralised heat pumps and chillers to modulate the network temperature, and shared energy flows between interconnected buildings. This paper presents a simulation model for the design and analysis of these systems. The model was developed using the Modelica language an
This paper introduces the first minimal solvers that jointly estimate lens distortion and affine rectification from repetitions of rigidly-transformed coplanar local features. The proposed solvers incorporate lens distortion into the camera model and extend accurate rectification to wide-angle images that contain nearly any type of coplanar repeated content. We demonstrate a principled approach to
Sweden developed during the first two decades of the post-war period into one of the wealthiest countries in the world. This change in the wealth of the country was accompanied by immigration on a previously unknown scale. Sweden’s remarkable economic growth has been facilitated by this immigrant flow, which consisted almost entirely of European labour migrants during the period up to the early 19
Speaker localization using microphone arrays depends on accurate time delay estimation techniques. For decades, methods based on the generalized cross correlation with phase transform (GCC-PHAT) have been widely adopted for this purpose. Recently, the GCC-PHAT has also been used to provide input features to neural networks in order to remove the effects of noise and reverberation, but at the cost
This paper presents the numerical results of combustion and soot recession in the Engine Combustion Network (ECN) Spray A and D flames using large eddy simulations (LES). The nominal injector nozzle diameters for the ECN Spray A and D are 90μm and 186μm. A two-equation soot model is implemented to model the soot formation and oxidation processes. The numerical model is validated by comparing the s
Severe congenital protein C deficiency (SCPCD) is rare and there is currently substantial variation in the management of this condition. A joint project by three Scientific and Standardization Committees of the ISTH: Plasma Coagulation Inhibitors, Pediatric/Neonatal Thrombosis and Hemostasis, and Women’s Health Issues in Thrombosis and Hemostasis, was developed to review the current evidence and h
Existing state-of-the-art estimation systems can detect 2d poses of multiple people in images quite reliably. In contrast, 3d pose estimation from a single image is ill-posed due to occlusion and depth ambiguities. Assuming access to multiple cameras, or given an active system able to position itself to observe the scene from multiple viewpoints, reconstructing 3d pose from 2d measurements becomes
Correlations between mean transverse momentum [pT] and anisotropic flow coefficients v2 or v3 are measured as a function of centrality in Pb–Pb and Xe–Xe collisions at sNN=5.02 TeV and 5.44 TeV, respectively, with ALICE. In addition, the recently proposed higher-order correlation between [pT], v2, and v3 is measured for the first time, which shows an anticorrelation for the presented centrality ra
This paper discusses a Python interface for the recently published Dune-Fem-DG module which provides highly efficient implementations of the discontinuous Galerkin (DG) method for solving a wide range of nonlinear partial differential equations (PDEs). Although the C++ interfaces of Dune-Fem-DG are highly flexible and customizable, a solid knowledge of C++ is necessary to make use of this powerful
The pentasaccharide glycoside corresponding to galactosylgloboside (SSEA-3), β-d-Gal p-(1 → 3)-β-d-Gal pNAc-(1 → 3)-α-d-Gal p-(1 → 4)-β-d-Gal p-(1 → 4)-β-d-Glc p-1-OCH2CH2Si-(CH3)3 (4), was synthesized via glycosylation (87%) of 2-(trimethylsilyl)ethyl 2,3,6-tri-O-benzyl-4-O-[2,3,6-tri-O-benzyl-4-O-(2,4,6-tri-O-benzyl-α-d-galactopyranosyl)-β-d- galactopyranosyl]-β-d-glucopyranoside (2) with the gl
With functions as diverse as communication, protection and thermoregulation, coloration is one of the most important traits in lizards. The ability to change colour as a function of varying social and environmental conditions is thus an important innovation. While colour change is present in animals ranging from squids, to fish and reptiles, not much is known about the mechanisms behind it. Tradit
Governments around the world have been shortening the leash on human rights non-governmental organization (NGO) watchdogs. Some see NGOs working in the field of human rights, and more recently, those working to fight impunity for serious violations, as Trojan Horses for foreign intervention in their internal affairs. Many worry that NGOs dictate United Nations (UN) human rights and international c
Pelvic floor reconstructive surgery (PFRS) has suffered from high recurrence rates ever since its birth. Implants were thus quickly employed, initially autologous grafts and allografts. Technological development led to the manufacturing of synthetic implants that were believed to provide the support needed during urinary incontinence and pelvic organ prolapse (POP) surgery. However, due to a surge
Antimony (Sb) is a toxic metalloid, which has been increasingly used in the brake lining of vehicles, and increased concentrations have been found in soils near abundant traffic. However, since very few investigations of Sb accumulation in urban vegetation have been undertaken there exists a knowledge gap. We studied the concentrations of Sb in leaves and needles of trees in the Gothenburg City ar
We have recently developed a method based on relativistic time-dependent density functional theory (TD-DFT) that allows the calculation of electronic spectra in solution (Creutzberg, Hedegård, J. Chem. Theory Comput.18, 2022, 3671). This method treats the solvent explicitly with a classical, polarizable embedding (PE) description. Furthermore, it employs the complex polarization propagator (CPP) f
Over the last decades, marketing literature has persistently been interested in how marketers and consumers alike engage with the past through past-themed brands, products, and services. However, our knowledge on past-themed marketing is scattered and treated in largely separated literature streams on retro, heritage, nostalgia, and vintage. This article reviews marketing literature on retro, heri
