The modeling of industrial combustion applications today is almost exclusively based on two-equation turbulence models. Despite its known limitations, the most the widely used model is still the standard k-ε model. The objective of this paper is to investigate the performance of two-equation turbulence models applied to a confined swirling flow. Numerical modeling of an axis-symmetric confined sud

Background: Multiple clinical practice guidelines and head computed tomography decision rules exist for emergency department (ED) triage of children with traumatic brain injury (TBI). These vary in structure, aim, target cohort, and outcomes, yet are used clinically in similar populations. We compared important clinical and practical characteristics of all major guidelines in a large, real-world p
A study of resonant structures in B+→D∗+D-K+ and B+→D∗-D+K+ decays is performed, using proton-proton collision data at center-of-mass energies of s=7, 8, and 13 TeV recorded by the LHCb experiment, corresponding to an integrated luminosity of 9 fb-1. A simultaneous amplitude fit is performed to the two channels with contributions from resonances decaying to D∗-D+ and D∗+D- states linked by C parit
Expectations of and prerequisites for Swedish school libraries is the subject of this master’s thesis. The purpose of the thesis is to gain insights into what a school library is expected to be and what is required to achieve it. The thesis focuses on the trade union DIK's award “World class school libraries” which is meant to function as a set of criteria for what a well-functioning school li
Konvergensen är ett starkt sätt att skapa ökat kundvärde på befintliga eller nya produkter och tjänster. Detta adderande värde för kunden sker huvudsakligen på två nivåer av konvergensen.: Tjänstekonvergensen, där man genom att erbjuda tjänster såväl fast som mobilt ökar tjänsens värde och på så sätt ger kunden ett ökat värde. Det ökade värdet av tjänsterna grundar sig i att de kommer att vara til
An unmanned ship can be designed without considering humancomfort, and can thus be constructed lighter, smaller and less expensive.It can carry out missions in rough terrain or be in areaswhere it would be dangerous for a human to operate. By not havingto support a crew, lengthy missions can be accepted, enabling, e.g.reconnaissance missions, or reducing emissions by lowering thespeed.Breakthrough
BACKGROUND: The majority of out-of-hospital cardiac arrests (OHCAs) occur at place residence, which is associated with worse outcomes in unselected prehospital populations. Our aim was to investigate whether location of arrest was associated with outcome in a selected group of initial survivors admitted to intensive care.METHODS: This is a post-hoc analysis of the Targeted Temperature Management a
Gas in scattering media absorption spectroscopy shortly called GASMAS, is a tunable diode laser spectroscopic technique developed for the measurement of gas present in turbid media. The technique relies on the sharp and specific absorption lines of gases which enables sensitive measurements of gas concentrations in the presence of a scattering solid medium with much broader absorption features. Th
Importance: Accurate blood-based biomarkers for Alzheimer disease (AD) might improve the diagnostic accuracy in primary care, referrals to memory clinics, and screenings for AD trials. Objective: To examine the accuracy of plasma β-amyloid (Aβ) and tau measured using fully automated assays together with other blood-based biomarkers to detect cerebral Aβ. Design, Setting, and Participants: Two pros
Objectives: The aim of this study was to investigate symptom prevalence, symptom relief, and palliative care indicators during the last week of life, comparing them for patients with motor neuron disease (MND), central nervous system tumors (CNS tumor), and other neurological diseases (OND). Material & Methods: Data were obtained from the Swedish Register for Palliative Care, which documents c
The effort to electrify society has in recent years resulted in major changes in the transportation sector. Charging time remains a challenge in several applications such as transportation and heavy machinery. A proposed solution that shortens the energy replenishment time and adds flexibility in loading the grid is to battery-swapping: exchanging the depleted battery for a fully charged one. In s
We investigated the role of cultural experience in the search advantage for happy faces. European British participants living in the UK, Asian Japanese participants living in Japan, and Asian Japanese participants living in the UK, were required to search for a happy or an angry face target against a background of neutral facial expressions, using Asian Japanese and European American faces. Result
Spectroscopic imaging is a widely employed diagnostic approach with applications span-ning several different disciplines. Although color-sensitive cameras are very common and used for everyday photography, scientific applications often require highly specific color sensitivity to avoid signal cross-talk and misinterpretations. Such systems are primarily based on sequential acquisition configuratio
Problemformulering: Byggprocessen är idag långsam, kostsam och genererar stora mängder spill och utsläpp. För att kunna möta bostadsbehovet från den snabbt växande befolkningsmängden måste tekniken utvecklas, den måste bli snabbare och mer kostnadseffektiv. Med ny teknik där betongelement tillverkas genom automatiserad och datorstyrd 3D-printning kan eventuellt hela betongbyggnadsprocessen effektiQuestion formulation: The construction process today is slow, costly and generates large amounts of waste and emissions. In order to meet housing needs of the rapidly growing population in a sustainable way, the technology must evolve; it must be faster and more cost-effective. New technology, where concrete is manufactured by automated and computer-controlled 3D-printing, can possibly streamline
ESS linjäraccelerator ska korrigera störningar innan de uppstår. I Lund pågår just nu bygget av europas nya anlägg- ning för forskning med neutronspridning, ESS. Neu- tronspridning är en icke-destuktiv metod för att stu- dera rörelser och strukturer på molekylnivå. Meto- den används som komplement till röntgenstrålning. På liknande sett som man med röntgenstrålning kan se igenom huden på en männisThe purpose of this thesis is to study beam-cavity interactions, with a focus on how to maintain an unperturbed acceleration field in a conducting cavity with a proton beam present. The impact on a cavity acceleration field from different perturbation sources is investigated through computer simulations of a theoreti- cal model based on a resonant circuit. Perturbations from the RF input pulse to
