Popular Abstract in Swedish Avhandlingen omfattar förutom en kort inledning, i huvudsak två delar: (1) Beskrivning av teorin bakom ett datorbaserat verktyg för simulering av termodynamiken i ett motorsystem, där främst motorer med Homogen Kompressionsantändning (Homogeneous Charge Compression Ignition, HCCI) avses. Med system avses förutom själva motorn, turboladdare, laddluftkylare, insug och avgThis thesis focuses on engine system simulation using thermodynamics and chemical kinetic models to investigate the performance and efficiency of Homogeneous Charge Compression Ignition (HCCI) engines for stationary applications. It includes the development of software as well as models for engine, turbocharger, intercooler, inlet and exhaust manifolds, wastegate valve, inlet air humidifier, inle

BACKGROUND: Diagnostic methods for the study of allergic reactions to Anisakis simplex (A.s.) based on whole-body extracts of the larva are clearly insufficient. OBJECTIVES: To study the allergenicity of the proteins secreted by the parasite. Comparison with somatic antigens and determination of their clinical importance in allergic patients were also addressed. METHODS: An excretory/secretory (E/

The spatial and spectral filtering characteristics of a microphone array can be greatly enhanced through the use of an appropriately designed spatial/spectral filter. In this paper, we consider the design of optimum, in the minimax sense, spatial/spectral filters. The optimum minimax design problem is solved using the new efficient computational technique of Jiang et al. Numerical results demonstr

To remain competitive in the field of manufacturing today, companies must constantly improve the automation loops within their production plants. This can be done by augmenting the automation applications with "smart services" such as supervisory-control applications or machine-learning inference algorithms. The downside is that these smart services are often hosted in a cloud infrastructure and t

Background: Vitamin A may have some influence on the immune system, but the role in allergy modulation is still unclear. Objective: To clarify whether high levels of retinoic acid (RA) affects allergic response in vivo, we used a murine experimental model of airway allergic disease. Methods: Ovalbumin (OVA)-immunization/OVA-challenge (OVA/OVA) and house dust mite (HDM)-immunization/HDM-challenge (

Denna uppsats syftar till att fastställa hur införandet av Enhetliga Patent och den Europeiska- och EU-patentdomstolen kommer att påverka läkemedelsindustrins val av patentansökningsförfarande när de ansöker om patent i Europa i framtiden. För att fastställa de förväntade effekterna av Enhetliga Patent på branschen har intervjuer med ett urval personer inom forskning- och utvecklingsföretag och enThis thesis aims to establish how the introduction of the Unitary Patent and the European and European Union Patent Court will affect the pharmaceutical industry’s choice of patent application route when applying for patents in Europe in the future. To establish the expected effect of the Unitary Patent on the industry interviews with a selection of professionals in the research and development in

Byggnadssektorns klimatpåverkan behöver minskas genom energieffektivisering men också genom att öka andel av förnybar energi i den energi som används. Värmelagring i byggnader kan vara ett effektivt sätt att flytta byggnadens behov av energianvändning för uppvärmning från tider då energisystemets koldioxidbelastning är hög till tider under ett dygn då det finns betydande tillgång på förnybar energ

I uppsatsen studerar jag hur Institutet för arbetsmarknadspolitisk utvärdering (IFAU) har följt upp och utvärderat det svenska friårsförsöket. Jag undersöker om deras tillvägagångssätt stämmer överens med hur man teoretiskt bör följa upp och utvärdera arbetsmarknadspolitiska program. Hemström med fleras (2002) ”Att följa upp och utvärdera arbetsmarknadspolitiska program” ligger som huvudsaklig teo

Background and objectives For unresectable peritoneal carcinomatosis (PC) median overall survival (OS) is 5-6 months. This article analyzes patients with PC from colorectal cancer (CRC) uneligible for debulking and hyperthermic intra-peritoneal chemotherapy, describing patient-and tumor-related factors possibly affecting survival. Patients and Methods From 2005 to 2009, 43 patients presented with

We report on a computational study of resonant inelastic x-ray scattering (RIXS), at different fluorine K-edge resonances of the SF6 molecule, and corresponding nonresonant x-ray emission. Previously measured polarization dependence in RIXS is reproduced and traced back to the local σ and π symmetry of the molecular orbitals and corresponding states involved in the RIXS process. Also electron-hole

The current conjecture towards Nordic fertility rates brings the focus on the state of advancement of the second demographic transition (SDT) in the region. Nordic countries’ SDT developments have been unique as they have not experienced the same low fertility as other countries. Yet, since 2010, Iceland lost nearly a quarter of its fertility and reached an all-time low total fertility rate (TFR)

It is often impossible to capture the sound one wants without capturing noise. Consequently, research has been done on noise filtering in audio signals. Currently deep learning algorithms are used for noise filtering. This thesis investigated the effects of noise and denoising on sound classification. The thesis used two standard datasets for clean sound and noise. FSD50K was chosen as clean soun

This study investigates the activist engagement strategies of U.S.-domiciled hedge funds when engaging with Japanese firms. The study forms a comparison of the engagement strategies both before Japan’s 2015 Corporate Governance Code and after. To create this comparison, two campaigns were examined. First, the U.S.-domiciled hedge fund Steel Partners and its campaign against Japanese firm Bull-Dog

Fifth Generation New Radio (5G NR) systems operating in the Millimeter-Wave (mmWave) bands, ranging from 24 to 43 GHz, put significant demands on User Equipment (UE) hardware required for the time-critical control of the digital beamforming. The UE side digital beamforming system needs to orchestrate tasks including: Receive (RX)/Transmit (TX) chain activation and deactivation, filter bank switchi

Syfte: Studiens syfte är att undersöka om det i teorin beskrivs faktorer inom hur man framgångsrikt kommunicerar en förändringsprocess som inte appliceras i praktiken, vilket i så fall kan ligga till grund för att en så stor del av förändringsprocesser inte implementeras. Metod: En kvalitativ tvärsnittsstudie utifrån en deduktiv ansats. Uppsatsens empiriska material insamlades genom semistrukturer

This thesis examines how the Swedish Armed Forces communicates its visual identity through Instagram, one of the most popular social media platforms today. The purpose is to analyze which visual elements the Swedish Armed Forces use to express their identity, which visual elements appear most in their Instagram posts, and how their existing visual identity manual is reflected on the platform. We a

Overheating in buildings is becoming a major concern and cause for various health issues. Existing research and previous studies on the issue were examined to acquire relevant information about the definition of overheating, its possible causes, and the heath impacts it could have on human health. The review included data on the current status of thermal comfort and overheating regulations in Swed
