Transient Analysis and Control for Scalable Network Systems

The rapidly evolving domain of network systems poses complex challenges, especially when considering scalability and transient behaviors. This thesis aims to address these challenges by offering insights into the transient analysis and control design tailored for large-scale network systems. The thesis consists of three papers, each of which contributes to the overarching goal of this work.The fir

Experimental and Numerical Analysis of an Active Pre-Chamber Engine Fuelled with Natural Gas

Increasingly stringent pollutant and CO2 emission standards require the car manufacturers to investigate innovative solutions to further improve the fuel economy and environmental impact of their fleets. Nowadays, NOx emissions standards are stringent for spark-ignition (SI) internal combustion engines (ICEs) and many techniques are investigated to limit these emissions. Among these, an extremely

Conceptual Framework for Telehealth Adoption in Indian Healthcare

India is a developing country with a large landmass and a huge socio-culturally, economically and, ethnically diverse population. The healthcare system for such a diverse and complex country could entail challenges anddifficulties in execution and outreach. Here, the emerging area of Telehealth could afford a place for itself in providing healthcare and health education to a large section of peopl

Left atrial dyssynchrony in veteran endurance athletes with and without paroxysmal atrial fibrillation

Background: Prolonged endurance exercise increase the risk of atrial fibrillation (AF) in men. Functional parameters may help separate physiological from pathological atrial remodeling in athletes. LA mechanical dispersion (LA MD) is associated with AF in the general population, but the associations between prolonged exercise, LA MD and AF are not known. Purpose: To describe LA MD in veteran athle

The association between sodium intake and coronary and carotid atherosclerosis in the general Swedish population

Aims: A high intake of salt raises blood pressure and the risk of cardiovascular disease. Previous studies have reported on the association between salt intake and carotid stenosis, but the association with coronary atherosclerosis has not been reported. Therefore, this project aimed at studying the association between salt intake and both carotid and coronary atherosclerosis in a contemporary com

Determinants of telehealth adoption in the Indian healthcare domain: an exploratory study

India is a developing country with a large landmass and a huge socio-culturally, economically and ethnically diverse population. The healthcare system for such a diverse and complex country entails challenges and difficulties in execution and outreach. Here, the emerging area of telehealth could afford a place for itself in providing healthcare and health education to a large section of people res

A Numerical Methodology for the Design of Active Prechambers in Spark-Ignition Engines

Active prechamber spark-ignition engines are a feasible and effective solution in reducing fuel consumption and pollutant emissions for internal combustion engines. However, reliable and low-cost numerical approaches need to be developed to support and speed-up their industrial design, considering their geometric complexity and the involved multiple-flow length scales. In this work, a computationa

The dynamics of touch-responsive gene expression in cereals

Wind, rain, herbivores, obstacles, neighbouring plants, etc. provide important mechanical cues to steer plant growth and survival. Mechanostimulation to stimulate yield and stress resistance of crops is of significant research interest, yet a molecular understanding of transcriptional responses to touch is largely absent in cereals. To address this, we performed whole-genome transcriptomics follow

Retracing the Vikings in the East : A review of Scandinavian-Islamic interfaces

De vanligaste kontakterna under vikingatiden ur ett svenskt perspektiv gick österut. Miljontals islamiska mynt flödade in i Skandinavien från Nordafrika, kalifatet och det samanidiska herraväldet i Centralasien. Deras ursprung varierade, och silverströmmens kronologi gör det möjligt att beskriva föränderliga relationer mellan aktörerna. Några välkända artefakter från samma riktning kom till SkandiThe most common contacts during the Viking Age from a Swedish perspective were to the East. Millions of Islamic coins flowed into Scandinavia from North Africa, the Caliphate, and the Samanid dominion in Central Asia. Their origins differed, and the temporality of the silver stream makes it possible to outline changing interfaces between the actors. Some well known artifacts from the same directio

Rapid manoeuvre of fan worms (Annelida: Sabellidae) through tubes

Multiple variables determine the success of an escape response of an animal, and the rapidity of the escape manoeuvre is often the most important. Fan worms (Annelida: Sabellidae) can rapidly withdraw their tentacles, which are covered in heavily ciliated ramifications called pinnules, into their tubes to protect them from approaching threats. Here, we explore the dynamic and mechanistic features

A reality check on the GARCH-MIDAS volatility models

We employ a battery of model evaluation tests for a broad set of GARCH-MIDAS models and account for data snooping bias. We document that inferences based on standard tests for GM variance components can be misleading. Our data mining free results show that the gain of macro-variables in forecasting total (long-run) variance by GM models is overstated (understated). Estimation of different componen

New insights into the pathophysiology and therapeutic targets of asthma and comorbid chronic rhinosinusitis with or without nasal polyposis

Asthma and chronic rhinosinusitis with nasal polyps (CRSwNP) or without (CRSsNP) are chronic respiratory diseases. These two disorders often co-exist based on common anatomical, immunological, histopathological, and pathophysiological basis. Usually, asthma with comorbid CRSwNP is driven by type 2 (T2) inflammation which predisposes to more severe, often intractable, disease. In the past two decad

På rätt sida av historien? Hbtq-rättigheter som global politik

Detta kapitel introducerar queera perspektiv på global politik med utgångspunkt i en diskussion om politisk mobilisering kring hbtq-frågor på nationell och transnationell nivå. Att diskutera global politik utifrån ett queerperspektiv handlar inte enbart om att ”lägga till” hbtq-personer. Snarare innebär en queer analys att kritiskt granska vissa av de antaganden kring säkerhet, makt och förtryck s
