Modelling of Stiffness and Hygroexpansion of Wood Fibre Composites

Paper 1The field of research involving the analytical modelling of the stiff ness and hygroexpansion of composite material is reviewed. This paper can be regarded as an introduction to the area of the mechanics of composite materials in general and to wood bre composites in particular. The most important models, such as the Reuss and Voigt bounds and the Halpin-Tsai, are described, along with theiPaper 1The eld of research involving the analytical modelling of the stiff ness and hygroexpansion of composite material is reviewed.

Ultra-stable and versatile high-energy resolution setup for attosecond photoelectron spectroscopy

Attosecond photoelectron spectroscopy has opened up for studying light–matter interaction on ultrafast time scales. It is often performed with interferometric experimental setups that require outstanding stability. We demonstrate and characterize in detail an actively stabilized, versatile, high spectral resolution attosecond beamline based on a Mach-Zehnder interferometer. The active stabilizatio

Uncertainty of B-value estimation in connection with magnitude distribution properties of small data sets

We evaluate the efficiency of the maximum likelihood estimator introduced by Aki (1965), using synthetic datasets exhibiting diverse but well defined properties. The deviation of the b-value estimation from its real value is quantified by Monte Carlo simulations as a function of catalogue features and data properties such as the sample size, the magnitude uncertainties distribution, the round-off

The Subscriptions to Mark’s Gospel and History of Reception

Den här artikeln granskar subskriptionerne på Markusevangeliet i 157 grekiska handskrifter, och noterar deras gradvisa utveckling från att vara identisk med titeln i den tidigaste fasen till att bli mer och mer utarbetad och betydelsefull för tolkningshistorien. Tidigt, vilket återspeglas i titeln, förknippades det andra evangeliet med Markus, känd för att vara Petrus lärjunge och tolk. Under det This article surveys the subscriptions to the Gospel of Mark in 157 Greek manuscripts, noting their gradual development from being identical to the title in the earliest phase to becoming more and more elaborate and significant for the history of interpretation. Early on, as reflected in the title, the Second Gospel was associated with Mark, known to be Peter’s disciple and interpreter. In the fou

Tångens metamorfos

Verken ställdes ut på samlingsutställningen 'Hur går det?' på Keramiskt Center i Höganäs. Verken är en del av forskningsprojektet 'Tångens potentiella mellanrum', inom vilket tångens materialitet undersöker och problematiserar. Verken utforskar mötet mellan uttryck och upplevelser av tången utifrån lera som material.

High Current Density Vertical Nanowire TFETs With I₆₀ > 1 μ A/ μ m

We present experimental data for a vertical, 22-nm-diameter InAs/(In)GaAsSb nanowire Tunnel Field-Effect Transistor that exhibits the highest reported I60 of 1.2 μA/μm , paving the way for low power applications. The transistor reaches a minimum subthreshold swing of 43 mV/dec at VDS = 300 mV with a sub-60 mV/dec operation over a wide current range. Combined with a high transconductance of 205 μS/

Modelling challenges of blockchain technology enabled healthcare sustainable supply chain management: a modified-total interpretive structural modelling approach

Blockchain technology (BCT) is beneficial for the Healthcare Sustainable Supply Chain (HSSC), and the adoption of this technology provides many benefits improving the performance of the supply chain, effortless information sharing, mitigation of data modification, etc. On the contrary, this study focuses on the various challenges that come in the path while adopting the BCT. For this, the present

Young learners and multilingualism : A study of learner attitudes before and after the introduction of a second foreign language to the curriculum

Whilst adults in Sweden place great importance on communicative competence in English, interest in learning other FLs and support for multilingualism are low. This is mirrored in the attitudes of pupils in compulsory and post-compulsory education, where English is a popular subject but opt-out and drop-out rates for FLs are high. Whilst international research has shown that initial enthusiasm for

Structural formation during bread baking in a combined microwave-convective oven determined by sub-second in-situ synchrotron X-ray microtomography

A new concept has been developed for characterizing the real-time evolution of the three-dimensional pore and lamella microstructure of bread during baking using synchrotron X-ray microtomography (SRµCT). A commercial, combined microwave-convective oven was modified and installed at the TOMCAT synchrotron tomography beamline at the Swiss Light Source (SLS), to capture the 3D dough-to-bread structu

DP-ACT: Decentralized Privacy-Preserving Asymmetric Digital Contact Tracing

Digital contact tracing substantially improves the identification of high-risk contacts during pandemics. Despite several attempts to encourage people to use digital contact-tracing applications by developing and rolling out decentralized privacy-preserving protocols (broadcasting pseudo-random IDs over Bluetooth Low Energy-BLE), the adoption of digital contact tracing mobile applications has been

Combining crop diversification practices can benefit cereal production in temperate climates

Diversifying cropping systems by increasing the number of cash and cover crops in crop rotation plays an important role in improving resource use efficiency and in promoting synergy between ecosystem processes. The objective of this study was to understand how the combination of crop diversification practices influences the performance of arable crop sequences in terms of crop grain yield, crop an

Three Structures Touching

Solo exhibition at Propellor Gallery, Santa Monica, USWhen Copenhagen-based Hasager first visited Santa Monica for a six-month residency in 2018, she was drawn to 18th Street’s Culture Mapping 90404 project, a resident-led oral history archive and mapping platform for the 90404 zip code, as it complemented her artistic process of plumbing the depths of personal memories, oral histories, and hyperl

Glued-In Rods for Timber Structures - Development of a Calculation Model

This report relates to GIROD WP1 – “Development of a calculation model”. WP1 consists of four sub-WPs: 1.1 “Theoretical work”, 1.2 “Bond line tests”, 1.3 “Tests for calibration” and 1.4 “Calibration of model”.In WP1.1 theoretical models for rational prediction of pull out strength have been developed. The models include a very simple ideal plastic model, a linear elastic fracture mechanics model,

Finite Element Analysis of Structure-acoustic Systems : Methods and Applications

Paper 1The problem in which a flexible structure interacts with an acoustic fluid is analysed by use of the finite element method. With increasing complexity of the geometry and when increasing the frequency limit is of interest, the number of degrees of freedom needed to describe the system becomes very large. To reduce the coupled system, modal analysis is performed in the structural and in the

Hybrid Quantized Signal Detection with a Bandwidth-Constrained Distributed Radar System

This paper addresses the hybrid quantized signal detection problem in a distributed radar system, where widely separated antennas transmit low-bit quantized data with varying quantization levels depending on the different bandwidth constraint for each channel to a fusion center. To enable a high detection performance with such hybrid quantized data, we formulate the generalized likelihood ratio, R

Comparison of disease severity in glaucoma patients identified by screening in the 1990s and in routine clinical care in the 2010s in Sweden

Background and PurposeIn a previous study comparing the amount of visual field damage at presentation in patients having open-angle glaucoma (OAG) identified through screening and in patients diagnosed in routine clinical practice in the 1990s, the damage was considerably worse in the clinically diagnosed patients. In the present study we compare visual field damage at presentation in the same 402

Navigating Family Reunification for Third Country Nationals: An Analyse of the Impact of Waiting Period Requirements on the Right to Family Life under ECHR and EU Law

The present thesis explores the requirement of the waiting period to grant family reunification to Third Country Nationals from the perspective of human rights law. It examines how this requirement, which currently forms a significant part of immigration policies within European member states, may impact TCNs' Right to family life under the European Convention on Human Rights (ECHR) and EU
