Operational systems, such as industrial automation, autonomous vehicles, and larger air/sea/landcrafts, often contain a large number of heavily connected systems with real-time requirements for their functionality. For such systems, detecting and responding to anomalies is both challenging and crucial. Until recently, such anomalies were monitored using heuristic methods, or even humans monitoring

Disasters can generate up to fifteen times the annual rates of waste generated by the impacted communities and overwhelm the capacities of waste management systems. Disaster waste influences almost every aspect of response and recovery, is risky, and can be time-consuming and costly to clean-up. Disaster waste management (DWM) is, therefore, a key, and often neglected step for response and recover

Som vi har märkt på grund av de senaste årens höga elpriser är en jämn elproduktion från grön energi väldigt viktig. Solkraft där man lagrar energi i smält salt kan användas för att sprida ut eltillverkningen på alla dygnets timmar. Utvinningen av saltets energi är då högst betydelsefull och denna har undersökts genom effektiva och simpla flödessimuleringar i detta arbete. Dessa flödessimuleringaTo be able to meet the global energy demands, a steady supply of green energy is required, even during sun- or windless hours. Concentrated solar power is a useful alternative, which can produce and store green energy by heating a heat transfer fluid (HTF) and extracting its energy via a heat exchanger. One such category of HTF is molten salts, and to understand and be able to model the behaviour

Hydrogen plays a pivotal role in the global energy transition, offering a clean and versatile energy carrier for a sustainable future. However, ensuring its safe use in industrial facilities requires reli- able prediction of dispersion from Venting Units (VUs). Traditional computational fluid dynamics (CFD) simulations provide high-fidelity results but are too slow for fast safety assessment and i

One of the most anticipated properties of high entropy alloys (HEA) is excellent oxidation resistance. AlxCoCrFeNi (x=0,0.3,0.6,1 mole) HEAs were synthesized by arc melting route, followed by 4 remelting operations to ensure compositional homogenization. Alloys with x = 0 and 0.3 show single phase FCC structure and x = 1 have intricate BCC+B2 structure, whereas x = 0.6 have dual phases – FCC and B

Decarbonising the global housing stock is imperative for reaching climate change targets. In the United Kingdom, hydrogen is currently being tested as a replacement fuel for natural gas, which could be used to supply low-carbon energy to parts of the country. Transitioning the residential sector towards a net-zero future will call for an inclusive understanding of consumer preferences for emerging

There are ongoing questions about the most effective wavelength for photobiomodulation (PBM) on major salivary glands due to the specific anatomical location and unique optical properties of the tissues surrounding the glands. The aim of this study was to analyze the photon propagation in the major salivary glands region of humans and rats using Monte Carlo (MC) stochastic simulation. Phantoms wer

Water erosion on arable land has since the beginning of the 80's been studied frequently in Sweden because it to a high extent contributes to losses of nutrients from fields. This study discusses water erosion on arable land in a study area in southern Sweden, with an emphasis upon its relations to topographical factors, soils and land use. In the study area another investigation of water eros

The European Union’s external democracy promotion has increasingly and widely been characterized by most of the field’s scholars, with its overwhelming focus on supporting the overall socio-economic developments rather than nurturing the political underpinnings of democracy. The European Neighbourhood Policy (ENP) has undertaken certain efforts to promote the shared values in the neighbourhood cou

This thesis addresses the complexities of the situation of the Roma in Romania and Spain and the challenges of including isolated groups in society. The main texts used for comparison come from the Council of Europe’s expert bodies: the European Commission Against Racism and Intolerance (ECRI), the Advisory Committee (ACFC) under the Framework Convention for the Protection of National Minorities (

A submerged submarine is highly sensitive to fires since the fire residues cannot be directly ventilated to the atmosphere. Deadly outcome could be the result if the submarine does not reach the surface within time or manages to purify the air while submerged. Reasons for not reaching the surface could be enemies at the surface or system failure. No Swedish submarines are today able to purify fire

Antagandet om att personer med ätstörningar är smala är fortfarande utbrett, trots att det finns ett signifikant samband mellan ätstörningar och obesitas. I linje med detta finns en kunskapslucka avseende skattningsformulär riktade mot att fånga ätstörningar och subkliniska besvär hos personer med obesitas. En systematisk litteraturöversikt genomfördes med syftet att hitta tillgängliga formulär, mThe assumption that people with eating disorders are skinny is still widespread, even though there is a co-occurrence between eating disorders and obesity. Despite this co-occurrence, there is a gap in the knowledge regarding questionnaires aimed at assessing eating disorders and subclinical symptoms for people with obesity. Therefore, a systematic review was conducted with the purpose of finding

Barn som berörs av avhysning ställs i likhet med barn som drabbas av utmätning av bostad inför risken att förlora sitt hem. En trygg hemmiljö anses vara av stor vikt för barnets utveckling och främja behovet av stabilitet. Barn som befinner sig i osäkra beroendesituationer riskerar att påverkas negativt på flera plan, och upplever inte sällan stark oro och försämrat psykiskt mående. I denna uppsChildren who are affected by an eviction are, like children affected by attachment and sale of a house due to enforceable debt, faced with the risk of losing their home. A safe home environment is considered to be of great importance for the child's development and promotes the need for stability. Studies show that children subject to unsettled housing situations tend to experience grave anxie

Växthuseffekten är ett av de största miljöproblemen som mänskligheten står inför. Den naturliga växthuseffekten är nödvändig för allt liv på jorden, men när växthusgaserna i atmosfären ökar på grund av CO2 utsläpp, stiger jordens medeltemperatur. Konsekvenserna av uppvärmningen är bland annat smältande isar, vattenbrist och naturkatastrofer. En av orsakerna till uppvärmningen är framför allt förbrN,N-diphenyl carbazolium salt has attracted interest for applications in anionic exchange membranes (AEM) due to its structural features and the high chemical stability that the compound exhibit. AEM are polymeric membranes with positively charged functional groups. They can be employed as electrolytes in alkaline fuel cells. In this project, different types of N,N-diphenyl carbazolium compounds w

The purpose of this study was to explore medically trained care givers’ views on their work with people with dementia, focusing on their professional discretion and the standardized tools they use in their daily work. The aim was to gain a deeper understanding of aspects of their work that overlap with social work. The method used was qualitative semi-structured interviews with six caregivers, wor

Domestic violence is an extensive social problem that family law secretaries are familiar with. Yet there seems to be a blindness and ignorance to subsequent violence that is not established within the practice as a matter of course and is not given any decisive importance in family law secretaries' assessments. The purpose of our study is to understand how family law secretaries reason about

Trender av svampbekämpningsmedlet Klorotalonil i gravidas blod över en 18-årsperiod Bekämpningsmedlet Klorotalonil (CHT) har funnits länge och använts på en mängd olika typer av grönsaker, vilket är förbjudet i Sverige och även Europa idag. Ändå hittades det nyligen i gravida skånska kvinnor och har fortsatt upptäckts i gravida kvinnors blod kontinuerligt under de senaste 18 åren.

Human exposure to environmental contaminants might occur via different routes, such as inhalation, skin contact, or ingestion. Exposure to several pesticides has been associated with adverse human health outcomes. Our aim was to assess the stability as well as temporal trends of

The European Spallation Source ESS, under construction in Lund, Sweden, aims to produce high-brightness and intensity neutrons for a multitude of experiments upon completion. An efficient production of neutrons requires elaborate understanding of the moderation process which slows the neutrons from relativistic speed to a kinetic energy of meV. The moderator used at the ESS will be partially made

In this paper regularization of the correlation matrix between futures contracts is examined. With starting point in the recently established HPCA framework (Avellaneda, 2019), a couple of different extensions to the one-factor model is suggested. Extensions are made in terms of adjusting the model according to different cluster structures. The data consists of futures contracts on a wide variety
