Digital twins have been gaining an immense interest in various fields over the last decade. Bringing conventional process simulation models into (near) real time are thought to provide valuable insights for operators, decision makers, and stakeholders in many industries. The objective of this paper is to describe two methods for implementing digital twins at water resource recovery facilities and
Cellular-based localization and sensing pave the way for a variety ofapplications across various domains, ranging from autonomous driv-ing to emergency care and intelligent traffic management. Althoughtraditional methods have been effective, they still face challenges such as therequirement for highly accurate models and the inherent complexity of thealgorithms. This thesis explores the potential
Preconcentration of methane (CH4) from air is a critical sampling step in the measurement of singly and doubly substituted isotopologue ratios. We demonstrate the potential for isotope fractionation during preconcentration onto and elution from the common trapping material HayeSep-D and investigate its significance in laser spectroscopy measurements. By altering the trapping temperature for adsorp
Achieving net-zero climate targets requires some level of carbon dioxide removal. Current assessments focus on tonnes of CO2 removed, without specifying what form these removals will take. Here, we show that countries’ climate pledges require approximately 1 (0.9–1.1) billion ha of land for removals. For over 40% of this area, the pledges envisage the conversion of existing land uses to forests, w
I en samtid där akademisk prestation är en allt viktigare aspekt för framtida framgång blir det angeläget att veta vilka faktorer som kan inverka på det. Anknytning har visat sig ha en väsentlig roll i vår utveckling och därav väcks frågeställningen kring vilken betydelse anknytning har för akademisk prestation. I den här systematiska narrativa kunskapsöversikten har vi granskat och eftersökt redaIn a time where academic achievement is a key factor for future success, the importance of knowing which factors have an impact on achievement is crucial. Parent-child attachment has shown to have an essential role in our development and therefore the question of which role attachment has on academic achievement is awoken. In this systematic narrative review we have examined and sought after exist
Background/Problematization: Iconic brands are the gold standard of branding and have established a central role in the consumers’ lives. Behind every iconic brand, we can find iconic products. Despite the importance of these products, iconic products are overlooked in academia. Few studies have explored the concept and there is no common definition or comprehensive framework. This is restrictive
Den bakomliggande orsaken till att islet amyloid polypeptide (IAPP) är cytotoxisk mot β-celler från bukspottkörteln tros vara prefibrillära oligomerer. Oligomererna skapas då IAPP ändrar konformation till amyloidfibriller. Förlusten av β-celler från cellklusterna har kopplats till typ II-diabetes. Ytterligare kunskap om hur man hindrar IAPP från att växla till den giftiga oligomerformen är oerhörtPrefibrillar oligomers are thought to be the “culprit” behind the cytotoxicity of islet amyloid polypeptide (IAPP) to pancreatic islet β-cells. The oligomers are generated in the process of IAPP’s conformational change into amyloid fibrils. The depletion of islet β-cells has been connected to type II diabetes. Knowledge of how to stop IAPP from switching into the cytotoxic oligomer form is of the
Under de senaste 30 åren har migrationsförvar (Engelska: Detention centers) blivit metoden att föredra när det gäller hanteringen av migrationsströmmarna i flera länder inom Europeiska Unionen (EU). I samband med den ökade användningen har det även skett en förändring från att stater har ett slags monopol gällande hanteringen av migrationsfunktioner till att stater delegerar (Engelska: Outsource) In the last three decades, detention centers have become the preferred method to manage the migration flow in multiple states within the European Union (EU). In correlation to the increasing use of detention centers, there has been a shift from states having a type of monopoly on migration management functions, to an increase of states outsourcing their responsibility to private companies. When st
Atypical femur fractures (AFF) are rare but clinically important fractures that have been associated with long-term mechanical loading and altered bone remodeling. In this study, a phase-field fatigue modeling framework was developed and calibrated to investigate fracture initiation in the femur under cyclic loading conditions representative of walking. The model was based on a previously publishe
Image compression is crucial for storing remote sensing data in space-constrained on-orbit systems. Current methods primarily follow two directions. The first combines wavelet transforms with post-processing, leveraging wavelets' sparse representation for multi-resolution analysis and efficient hardware implementation. The second employs compressed sensing (CS), which shifts complexity to the deco
we present rearing records of Eulophidae resulting from five years of collecting leafminers and other herbivorous insects throughout the United States. These include the first documented hosts for Chrysocharis beckeri Yoshimoto, C. minuta (hansson), Closterocerus damastes walker (identification tentative), Diaulinopsis albiscapus (girault), Elasmus borrowi girault, Neochrysocharis cyaneoviridis ha
Den ökade efterfrågan och turismen i Stockholms skärgård har skapat en identitetsmässig konflikt, där bebyggelseutvecklingen främst drivs av kommersiella besöksnäringar och privata fritidshus. Skärgårdsmiljön balanserar idag mellan strikt skyddade naturområden och exklusiva, privatiserade strandtomter, vilket lämnar lite utrymme för ett levande permanentliv. För att skärgården ska förbli en fungerThe growing demand and tourism in the Stockholm archipelago have created a conflict of identity, where property development is primarily driven by commercial hospitality industries and private seasonal housing. Today, the archipelago environment balances between strictly protected natural areas and exclusive, privatized shorelines, leaving little room for a vibrant, year-round community. For the a
Biogenic volatile organic compounds (BVOC) are known as hydrocarbons emitted into the atmosphere from the biosphere. They have physiological and ecological functions such as communication within the plant and plant – plant, protection against environmental stress factors and defense against herbivores attack. Coniferous forests are known to produce larger quantities of BVOCs, especially terpenes,
En stor del av samhällets miljöpåverkan kommer från bygg- och fastighetssektorn. Från årsskiftet 2022 finns det nya krav för nybyggnationer på att en klimatdeklaration ska genomföras för bärande konstruktionsdelar, innerväggar samt klimatskärmar. Kraven kan vara ett startskott för att fler delar i byggnader ska klimatdeklareras. Projekt Villazero, ett småhus som uppförs i Borlänge av Fiskarhedenvi
This thesis was dedicated to investigating the use of different parameter update schemes for Hidden Markov models with time-varying parameters, with an emphasis on developing alternatives to the quasi-Newton step. The focus was on applications to financial returns, using data from the S\&P-500 and the Nikkei index, and for comparison, a trial using synthetic data was also performed. Different
Introduction:The XenX is a small animal irradiation system that acquires high-resolution cone-beam tomography (CBCT) images of small animals and treats small animals with higher precision than medical linear accelerators. MuriSlice is a software for CBCT image reconstruction. This thesis aims to optimise the CBCT image reconstruction protocol in MuriSlice to enable the segmentation of CBCT images
After 9/11 then U.S president George W Bush declared ”the war against terrorism”. He stated that al-Qaeda and Taliban prisoners were “unlawful combatants”. The significance of this term placed all persons considered as “unlawful combatants” outside the scope and protection of International Humanitarian Law (IHL), which is the law that applies in armed conflicts. This thesis is a comparison between
