Alla har vi någon gång behövt använda oss av GPS för att hitta vägen eller se var vi är. Då har man antagligen också upptäckt att GPS inte alltid fungerar som den ska. I detta examensarbete undersöker vi ett alternativ till GPS som använder mobilnätet för att positionera med hjälp av maskininlärning. GPS-positionering kan ha en precision på mindre än 5 meter i öppna miljöer, men som tidigare nämnGNSS is currently the most prominent method for outdoor positioning, providing an accuracy of approximately 5 metres in good conditions. However, for environments such as dense city areas or indoors, a GNSS signal reception might not be possible. An alternative method of positioning is the fingerprint-based method, which has been widely adopted for indoor positioning by sampling the signal strengt

The course of this thesis takes its starting point from a question inspired by the work of architect and artist Allan Wexler; How can one create a building that emanates from one’s subconscious? Wexler states that he aims to create buildings in the same manner as a potter throws a pot on a wheel, without hesitation, in a kind of stream of consciousness fashion. The question about the subconscious

This paper investigates how do venture builders manage the process of developing venture opportunities in collaboration with corporates. This research followed a qualitative approach using a cross-sectional study design. Ten semi-structured interviews with employees from four different venture builder organizations are the primary data source. The data is inductively analyzed using Gioia, Corley,

Since Robotic Process Automation (RPA) is expected to have the potential of bringing substantial benefits to many of today’s businesses, RPA initiatives are taking an increasingly bigger role in various organizations. Previous research has identified a lack of guidelines in successfully adopting RPA. This deficit includes, but is not limited to a knowledge gap in the adoption of RPA by IT service

I ett allt mer digitaliserat samhälle, så är omställningen påtaglig även inom läkemedelsindustrin. Kontrollsystemet Orbit utvecklades vid Lunds Universitets avdelning för kemiteknik, för att möjliggöra automatisering av nedströmsprocesser baserade på ÄKTA-system. Kontrollsystemet har en inbyggd simulator, som tillåter en användare att genomföra simulerade experiment istället för fysiska. Målet medIn an ever more digitilized society, the transition is palpable also in the pharmaceutical industry. The control system Orbit was developed at the department of chemical engineering at Lund University, to be able to automate downstream processes based on the ÄKTA-system. The control system has a built-in simulator, enabling the user to run simulated experiments instead of actual physical experimen

From literature review a theoretical research model was developed describing the process for designing a performance measurement system fit for the company culture, strategic direction, and stakeholder perspective. Following the model, the definition of high performance for the department was investigated and success factors were formulated from interview results. These success factors were accord

Purpose: This study aims to examine changes in the acquired company’s MCS post-M&A and how the employees perceive this change. Further, the purpose is to investigate how employees' perceptions affect the employees’ motivation and identity. Methodology: This study follows a qualitative research approach by analyzing an acquired company in the logistic industry. Data was collected through s

Multiplex separation of mixed cell samples is required in a variety of clinical and research applications. Herein, we present an acoustic microchip with multiple outlets and integrated pre-alignment channel to enable high performance and label-free separation of three different cell or particle fractions simultaneously at high sample throughput. By implementing a new cooling system for rigorous t

Disorder is an intrinsic feature of all solids, from crystals of atoms to superlattices of colloidal nanoparticles. Unlike atomic crystals, in nanocrystal superlattices, a single misplaced particle can affect the positions of neighbors over long distances, leading to cumulative disorder. This elusive form of collective particle displacement leaves clear signatures in diffraction, but little i

Heart failure (HF) is a major contributor to global morbidity and mortality. While distinct clinical subtypes, defined by etiology and left ventricular ejection fraction, are well recognized, their genetic determinants remain inadequately understood. In this study, we report a genome-wide association study of HF and its subtypes in a sample of 1.9 million individuals. A total of 153,174 individual

Astrocytes play a crucial role in the onset and progression of amyotrophic lateral sclerosis (ALS), a fatal disorder marked by the degeneration of motor neurons (MNs) in the central nervous system. Although astrocytes in ALS are known to be toxic to MNs, the pathological changes leading to their neurotoxic phenotype remain poorly understood. In this study, we generated human astrocytes from induce

Retrospective, propensity-score-adjusted (PSA) studies have indicated to practitioners in the field that contrast-induced acute kidney injury (AKI) after contrast-enhanced CT (CECT) is of minor importance or even non-existent. This has led to controversies between clinicians demanding CECT not to miss any diagnoses and radiologists reluctant or even refusing CECT in risky patients. A critical revi

This chapter examines elite polarisation as a challenge to governance in parliamentary democracies. We emphasise the distinction between ideological polarisation based on substantive policy disagreements from affective polarisation, characterised by identity-based animosity that creates barriers to cooperation even when policy compromise might otherwise be possible. While parliamentary regimes hav

Multi-electron donation remains a challenge for CO2 photocatalytic conversion to multi-electron products due to the efficient Auger recombination or annihilation at multiple excitation conditions for conventional molecules or semiconductor photocatalysts. In this paper, we demonstrated possible multi-electron donation within a quantum dot (QD)/metal complex hybrid photocatalyst system when multipl

Imaging the strain in nanoscale heterostructures is challenging since it requires a combination of high strain sensitivity and spatial resolution. Here, we show that three-dimensional (3D) Bragg coherent diffraction imaging (BCDI) can be used to image the strain in a single InP segment within an axially heterostructured GaInP-InP nanowire. We use a 350 nm-diameter X-ray beam, which is smaller than

Implicit sequence learning (ISL) has been studied using a variety of tasks two of which have been particularly influential: the serial reaction time task (SRTT) and the artificial grammar learning (AGL) task, stemming from the motor learning domain and psycholinguistics, respectively. SRTTs measure the difference in response times between a repeatedly presented and random sequences of keyboard pre

Collagen VII is an essential anchoring protein in the basement membrane zone, maintaining the attachment of stratified and pseudostratified epithelia to the underlying interstitial matrix. However, collagen VII is largely unexplored in normal lungs and idiopathic pulmonary fibrosis (IPF), a disease characterized by excessive accumulation of extracellular matrix (ECM) and aberrant re-epithelializat

Background: International research demonstrates an association between arts and culture activities and health and wellbeing. A similar association exists for sports event attendance and health. The aim of this study was to investigate associations between arts and culture engagement and attending sports events during the past year and self-rated health (SRH). Methods: A cross-sectional study. A pu
