Massive multiple-input multiple-out (MIMO) technology is vital in millimeter-wave (mmWave) bands to obtain large array gains. However, there are practical challenges, such as high hardware cost and power consumption in such systems. A promising solution to these problems is to adopt a hybrid beamforming architecture. This architecture has a much lower number of transceiver (TRx) chains than the to
We used Swedish national-register data (N = 2,828,777) to examine divorce and its associated patterns of family genetic-risk scores (FGRSs; personalized measures of genetic risk inferred from diagnoses in relatives) across 10 psychiatric disorders: major depression, anxiety disorders, obsessive compulsive disorder, bipolar disorder, schizophrenia, anorexia nervosa, alcohol use disorder, drug use d
This chapter addresses the organization known as the Satanic Reds, which was founded in the latter half of the 1990s by Tani Jantsang and Philip Marsh. The organization has been described as a ”virtual audience cult,” and even though it is clear that several people have contributed in shaping it, the organization has been especially influenced by its two founders. Jantsang and Marsh have spoken fo
In this paper we address absolute camera pose estimation. An efficient (and standard) way to solve this problem, is to use sparse keypoint correspondences. In many cases point features are not available, or are unstable over time and viewing conditions. We propose a framework based on silhouettes of quadric surfaces, with special emphasis on cylinders. We provide mathematical analysis of the probl
This thesis contributes to the credit risk literature by analyzing the Merton model’s ability to replicate credit default swap (CDS) spreads. Since defaults are rare events, resulting in low statistical power, the method is evaluated by comparing model implied CDS spreads to market ones. The data sample used includes quarterly observations from 2015 to 2024 for 44 firms included in the NASDAQ Comp
Det är ett ofta återkommande problem för hornister att utöka sitt register, i detta fall höjdregistret. Det finns också en uppsjö av olika beskrivna övningsmetoder med detta syfte. Denna uppsats diskuterar, ur ett autoetnografiskt perspektiv, utökning av höjdregistret med hjälp av Brophys och Lejonclous övningsmetoder. Övningarna inkorporerades i den dagliga övningsrutinen och dokumenterades både
Title: Planning for Supplier Base Reduction - understanding Supplier Base Reduction’s role in purchasing. A case study at Alfa Laval AB Authors: Fabian Karlsson and Sebastian Eriksson-Ritzén Supervisors: Ala Pazirandeh, Department of Industrial Management and Logistics, Lund University Markus Ekendahl, Alfa Laval AB Background: Today individual businesses do not compete as isolated entities, but r
Background/Aims: We assessed how the novel PrisMax continuous renal replacement therapy (CRRT) system performed in a prospective international multicentre setting. We compared this device to its predecessor, the Prismaflex, with regards to multiple treatment parameters. Additionally, we performed a survey, aiming to measure user satisfaction. Methods: Data was prospectively collected from 7 intens
There have been increasing theoretical speculations and observational indications that certain globular clusters (GCs) could contain a sizeable population of stellar mass black holes (BHs). In this paper, we shortlist at least 29 Galactic GCs that could be hosting a subsystem of BHs (BHS). In a companion paper, we analysed results from a wide array of GC models (simulated with the MOCCA code for c
Unnecessary food waste in Sweden is approximately 1,2 billion kilograms each year and this has consequences for both the environment and resources. The purpose of this project is to investigate if it is possible to reduce the unnecessary food waste, by selling cured meat products to a lower price in supermarkets, after the expired date but at the same time take people’s health into account. Focus
Mikroskopiska echinodermfossil har undersökts ur prover från täljstensintervallet och intillig-gande delar av ’lanna’- och ’holenkalkstenen’ i Hällekis stenbrott, Västergötland. Den undersökta sektionen är från översta volkhov och mellersta kunda, darriwilian (mellanordovicium). Tidigare studier har konkluderat att en regression/transgression skedde under den undersökta perioden, vilket bekräftas Microscopic echinoderms were studied in acid-insoluble residues from the Lanna and Holen limestones at Hällekis, Västergötland, Sweden. The section studied spans the uppermost Volkhov and lower–middle Kunda Baltoscandian stages, within the Darriwillian global Stage (Middle Ordovician). The echinoderms show an increase in abundance, accompanying falling sea levels during the well-recognized regress
This report aims to examine the economic conditions of photovoltaic systems in sports halls. It also intends to examine if it is economically viable to use the excess production from the solar electricity to heat up a hot water storage tank instead of selling it into the grid. This will be answered by studying Knislinge sports hall. Two different configurations of the solar system were investigat
Large companies in today’s business environment are to a great extent depending on their credit score by rating institutes like Moody’s and Standard & Poor’s. There is however indications that these big institutes are not always rating companies accurately. This is why this thesis aims at developing a new credit rating model, CRITA-Score, with the objective of determining a company’s financial
The doctoral dissertation is a key component of postgraduate education that plays an important role for knowledge production and hence the development of a discipline. Swedish human geography currently lacks an overview of dissertations. This article fills this knowledge gap by reporting findings from a unique database covering all doctoral dissertations between 1884 and 2015. The paper focuses on
Swedish emigration to America is a topic that does not hold a major position in Swedish historical research anymore. At one time, during the 1960s and 1970s, there were a major research project, Sweden and America after 1860, that focused primarily on the reasons of the migration, the demographics of the migration and to some extent what happened to the emigrants in America. The research project d
