This paper introduces the use of a multi-zone modelling approach for analysing smoke spread in tunnels. The approach suggested in this paper is based on an existing model, i.e., the Multi-Zone Fire model developed for large spaces. The Multi-Zone Fire model has been adapted and modified for tunnel fire scenarios by including features that consider longitudinal ventilation flow, tunnel gradient and
Social influence is largely recognized as a key factor in opinion formation processes. Recently, the role of external forces in inducing opinion displacement and polarization in social networks has attracted significant attention. This is in particular motivated by the necessity to understand and possibly prevent interference phenomena during political campaigns and elections. In this paper, we fo
The use of charge balance functions in heavy-ion collision studies was initially proposed as a probe of delayed hadronization and two-stage quark production in these collisions. It later emerged that general balance functions can also serve as a probe of the diffusivity of light quarks as well as the evolution of the systems formed in heavy-ion collisions. In this work, we reexamine the formulatio
Ukraine’s recent success on the battlefield has encouraged discussion on potential changes to Russia’s political setup. While a new leader would be needed, more fundamental change would be required if the country is to embark on a path towards democracy. The key issue lies in Moscow’s relations with its periphery, an exploitative relationship that has persisted for centuries.The war in Ukraine has
INTRODUCTION: Treatment efficacy of reflex syncope is mainly related to the mechanism underlying syncope rather than its etiology or clinical presentation. The predominant mechanism underlying reflex syncope can be assigned to hypotensive or to bradycardic phenotypes.AREAS COVERED: Methodology and diagnostic criteria of the most useful tests for the identification of hypotensive and bradycardic ph
Den andra enkäten i den Svenska Handelslogistik-panelen understryker lagrets strategiska betydelse för att möta förväntningar från kunder, och visar på flera intressanta trender för utveckling och automatisering av handelns logistiknätverk och lager. Vi undersökte vilka strategiska logistikutmaningar som är viktigast för lagret i dagsläget och fem år framåt.

In recent years, since the cloud can provide tremendous advantages regarding storage and computing resources, the industry has been motivated to move industrial control systems to the cloud. However, the cloud also introduces significant security challenges since moving control systems to the cloud can enable attackers to infiltrate the system and establish an attack that can lead to damages and d
Improvements in the efficiency of combustion within a vehicle can lead to reductions in the emission of harmful pollutants and increased fuel efficiency. Gas sensors have a role to play in this process, since they can provide real time feedback to vehicular fuel and emissions management systems as well as reducing the discrepancy between emissions observed in factory tests and 'real world' scenari
Background: Moderate-to-severe hemophilia B is treated with lifelong, continuous coagulation factor IX replacement to prevent bleeding. Gene therapy for hemophilia B aims to establish sustained factor IX activity, thereby protecting against bleeding without burdensome factor IX replacement. Methods: In this open-label, phase 3 study, after a lead-in period (≥6 months) of factor IX prophylaxis, we
Systems that interact with the environment around them generally run some periodic tasks. This class of systems include, among others, embedded control systems. Embedded controllers have been proven vulnerable to various security attacks, including attacks that alter sensor and actuator data and attacks that disrupt the calculation of the control signals. In this paper, we propose, and implement,
This themed journal issue provides many examples of ways forward in the study of death and memory in the Viking world. While all contributions demonstrate that there are exciting new ways to study remains from funerary contexts that focus on different forms of citation involving material culture and monuments, this article will very briefly discuss dimensions that have not been addressed here. Spe
We extend the generalized information criteria for high-dimensional penalizedmodels to sparse statistical jump models, a new class of statistically robust and computationally efficient alternatives to hidden Markov models. In a simulation study, we demonstrate that the new generalized information criteria selects the correct hyperparameters with high probability. Finally, providing an empirical ap
The problem of estimating the node density in ad hoc networks is a significant one for protocol design. In molecular nanonetworks, the node density estimation problem poses additional challenges due to the limited processing and communication capabilities of the network nodes which necessitate the design of simple to implement distributed solutions, and the diffusion based communication channel wh
I denna rapport redovisas populationstrender för 224 svenska fågelarter för olika långa tidsperioder, samt korttidstrender för 12 arter av större däggdjur. Fåglarna har räknats höst, vinter, vår och sommar enligt strikt standardiserade metoder. Sommar- respektive vinterpunktrutter har räknats sedan 1975, i huvudsak i södra Sverige. Standardrutterna räknas också på sommaren (sedan 1996)men täcker hWe present the results of the Swedish Bird Survey, a project run by the Department of Biology, Lund University, as a part of the National Monitoring Programme of the Swedish Environmental Protection Agency. The results for 2022 include data from: 546 winter point counts in 2021/2022 (47th winter), ofwhich 254 were carried out during the Christmas/New Year count, 209 summer point count routes (48th
Nanotechnology is the science of making and using very small structures. As the scales of the constructions become smaller, the existing methods of making these structures - lithography, etching and micromoulding - although constantly improving, will reach physical limits. To overcome the limitations and create smaller, designed and ordered structures, a so-called 'bottom-up' approach must be used
