This study aims to predict saving behavior using Artificial Neural Network (ANN), XGBoost, and Support Vector Machine (SVM) algorithms. First, 25 variables were chosen from the original 217 questions asked by the National Financial Capability Well-Being Survey (2018) NFCS, using exploratory data analysis. K-means clustering was applied to determine the optimal number of saving classes (k=5) to inc
Abstract Background This study defines enterprise mobility as “The set of technology, applications, processes and policies that support the possibility to perform business activities anywhere at any time”. Enterprise Mobility is one of the main trends in the enterprise ICT environment and a leading vendor describes it as we are entering a new wave of Enterprise Computing called consumer-driven Mob
Abstract Problem: While it has been extensively studied which personal characteristics enhance entrepreneurial learning from failure, the mechanisms of how those characteristics contribute to entrepreneurial learning process has not yet been fully understood. Aim: Through a comprehensive model, this research aims to explore how different personal characteristics influence the different stages o
The purpose of this study was to investigate how women working for different women’s organizations within civil society in Zimbabwe perceive and experience their own as well as other women’s ability and existing opportunities to influence and participate in politics and decision-making. Several research questions were elaborated that address the role of the women’s organizations, the opportunities
Avancerad användning av glas som konstruktionsmaterial i pelare och balkar har blivit allt vanligare de senaste åren. Detta arbete redogör för vilka metoder och normer som kan användas för att dimensionera glasbalkar i bärande konstruktioner och vilken typ av glasbalk som är lämpligast ur hållfasthets och säkerhets synpunkt. Tidigare har glaset mest använts i fönster där det inte har haft en bäran

Homogeneous Charge Compression Ignition (HCCI) is a promising but challenging combustion engine concept. The potential for good fuel economy and low emissions is high but the transient performance required for automotive applications presents a few problems still to be solved. The focus of this work is identification of the process dynamics. An ARX type model is fitted to input-output data. A meth
Homogeneous Charge Compression Ignition (HCCI) combustion lacks direct ignition timing control, instead the auto ignition depends on the operating condition. Since auto ignition of a homogeneous mixture is very sensitive to operating condition a fast combustion timing control is necessary for reliable operation, the ignition timing control design requiring appropriate models and system output vari
This paper offers a two-zone, physical, NOx model with low computational cost, implemented in C on an embedded system. The model is able to compute NOx-emission formation with high time resolution during an engine cycle. To do this the model takes cylinder pressure and injected fuel amount as inputs and produces NO concentration as output. The model as such is not new, nevertheless the physical ba
Strain and interactions at grain boundaries during solid-phase crystallization are known to play a significant role in the functional properties of polycrystalline materials. However, elucidating three-dimensional nanoscale grain morphology, kinetics, and strain under realistic conditions is challenging. Here, we image a single-grain growth during the amorphous-to-polycrystalline transition in tec
Objective To investigate the admission rate to neonatal care and neonatal morbidity after maternal use of antipsychotics during pregnancy. Design A population-based register study. Setting Information on all singleton births between July 2006 and December 2017 in Sweden including data on prescription drugs, deliveries and infants' health was obtained from the Swedish Medical Birth Register, the Pr
BACKGROUND: Transmission of coronavirus disease 2019 (COVID-19) can occur through inhalation of fine droplets or aerosols containing infectious virus. The objective of this study was to identify situations, patient characteristics, environmental parameters, and aerosol-generating procedures (AGPs) associated with airborne severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus.METHODS:
Since the 1970s, environment and energy-related problems have moved to centre stage on many political, business and research agendas. The notion of sustainable development has emerged as the dominant global discourse to adapt societies and economies to novel modes of production and consumption in areas such as transport, energy, housing, agriculture and food. For such shifts, new technology and te
Quantum annealing is a promising approach for obtaining good approximate solutions to difficult optimization problems. Folding a protein sequence into its minimum-energy structure represents such a problem. For testing new algorithms and technologies for this task, the minimal lattice-based [hydrophobic (H) or polar (P) beads] HP model is well suited, as it represents a considerable challenge desp
Aim: To investigate the predictive ability of the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) Motor Index, in children born extremely preterm (<27 gestational weeks) without cerebral palsy. Methods: Children from the EXPRESS study (all extremely preterm births in Sweden, 2004–2007) without neurosensory impairments assessed with Bayley-III at 2.5 years corrected age
Mobility is essential to our modern world to move people and goods. However, mobility has also its downside as transport sectors are substantial emitters of greenhouse gases and air pollutants. Increasingly energy efficient combustion engines and turbines, as well as electrification and carbon-neutral fuels, will reduce the climate impacts of transportation. When such technologies are combined wit
Industrial packaging plays an important role in the performance and environmental efficiency of supplychains. Despite it being so important, the implications that industrial packaging decisions have on thelogistics operations (and vice-versa) are not completely understood. This thesis contributes to theunderstanding of the impacts of sustainable industrial packaging by discussing the importance of
In this chapter, we argue that policy-making aiming to achieve environmentally sustainable transitions of the economy is in need of a solid empirical evidence base. Conventional measurement concepts used for example by the EU based on sector-classifications deliver highly biased pictures. We propose measurement concepts based on the use of green skills and human capital, validate key assumptions o
Background: Pre-hospital electrocardiogram (ECG) transmission to an expert for interpretation and triage reduces time to acute percutaneous coronary intervention (PCI) in patients with ST elevation Myocardial Infarction (STEMI). In order to detect all STEMI patients, the ECG should be transmitted in all cases of suspected acute cardiac ischemia. The aim of this study was to examine the ability of
