Sömnsvårigheter är vanliga i befolkningen och insomni utgör en av de mest förekommande sömnstörningarna med påtagliga konsekvenser för dagtida funktion och psykiskt välbefinnande. Flera sociodemografiska och kliniska riskfaktorer har identifierats, men kunskapen är begränsad om hur dessa faktorer tillsammans samvarierar med symtomens svårighetsgrad, behandling och önskemål om hjälp i primärvården.Sleep difficulties are frequently reported in the general population, and insomnia is among the most prevalent of sleep disorders, with substantial consequences for daytime functioning and psychological well-being. Prior studies have linked insomnia to several sociodemographic and clinical factors. However, knowledge is limited in how these factors together relate to symptom severity, treatment pa

This study investigates the interaction problem between a differentialdrive mobile manipulator and one-degree-of-freedom (1-DoF) mechanisms. While previous research has focused on stationary robotic platforms, this work puts emphasis on mobile interaction. Building upon a previously proposed adaptive control strategy for fixed-base manipulators, a holistic control framework is developed to coordin

Studien syftar till att undersöka om och hur fastighetsförvaltningen beaktas genom hela byggprocessen i nybyggnadsprojekt och hur det kan förbättras. Målsättning är att besvara de för studien relevanta frågeställningarna. Frågeställningarna som studien åsyftar att besvara kommer att betraktas med ekonomisk och ekologisk hållbarhet i åtanke. Studien har genomförts som en kvalitativ studie baserat The study aims to examine if, and how, facility management is considered throughout the construction process of a project, and how it can be improved. The aim is to answer the questions at issue. The questions of issue will be studied with an economic and ecological sustainability perspective. The study has been implemented as a qualitative study based on a document analysis of two construction p

Today’s climate crisis entails a need to change our ways of living, where an important aspect of meeting climate goals is a switch to renewable energy production. This bachelor thesis aims to explore the renewable energy transition, through a qualitative case study of a Swedish municipality in which southern Sweden’s biggest wind power park is being built. The research questions are on which geogr

Money is central to capitalism and its sustainability crises. This article argues that it is not money itself, but its internal design and governance – how it is created, distributed, and governed – that drives inequality, ecological degradation, and unsustainable growth. Yet, money’s architecture is not fixed; it can be reimagined to foster fairer, greener economies.Approaching money as a socio-t

Spiral spin liquids are an exotic class of correlated paramagnets with an enigmatic magnetic ground state composed of a degenerate manifold of fluctuating spin spirals. Experimental realizations of the spiral spin liquid are scarce, mainly due to the prominence of structural distortions in candidate materials that can trigger order-by-disorder transitions to more conventionally ordered magnetic gr

Formulating Research Problems addresses one of the most critical yet often overlooked aspects of research: how to define and frame the problem at the heart of a study. While most research methods texts devote only a few pages to this question, Johan Alvehus offers a dedicated, accessible, and practical guide that helps students move beyond vague topics toward the development of clear, rigorous, an

This paper presents PyEtSimul, an open-source Python-based framework for simulating video-based eye trackers by generating synthetic eye features through geometric modeling. The framework allows flexible positioning of eyes, cameras, and light sources in 3D space, with controlled variation of eye anatomical features and camera properties. PyEtSimul generalizes corneal modeling by representing the

Kritiken som har riktats mot regeringens angiverilag är högst befogad – förslaget innebär i praktiken att offentliganställda görs till gränspoliser, menar fyra forskare från universitet och högskolor i Lund, Malmö och Stockholm.En samförfattad debattartikel inom forskningsprojektet HUMASP, av Christina Johnsson, lektor i offentlig rätt och mänskliga rättigheter vid Malmö universitet. Jacob Lind, l

First, we present a new algorithm for the single-source shortest paths problem (SSSP) in edge-weighted directed graphs, with n vertices, m edges, and both positive and negative real edge weights. For a positive integer parameter t, in O(tm) time the algorithm finds for each vertex v a path distance from the source to v not exceeding that given by the shortest path from the source to v among the so

Populärvetenskaplig sammanfattning: Biologisk mångfald innebär variationsrikedom bland alla levande organismer i alla miljöer, på land som i vatten. Utveckling av snabba noggranna metoder för övervakning av landskap och biologisk mångfald är därför av hög prioritet i Sverige och resten av Europa. På grund av landskapsanalysens komplexitet, har ett behov av att kvantifiera landskapets ekologiska egA need to develop methods for quantifying the landscape in means of improving the monitoring of the biological diversity has become more necessary in recent years. Landscape indices are one way of quantifying the landscape. The method gives an opportunity to treat data statistically and to compare the patterns on different scales. The aim of the paper is to evaluate two indices, a shape index and

Hur skapar man samsyn och samarbete i en kommunal koncern där förvaltningar tidigare tänkte i stuprör? I Höganäs växte en kultur av gemensamt ansvar fram genom vardagliga berättelser och budgetprocessen. Den här artikeln berättar historien om hur kommunen etablerade en koncernledningsgrupp för att styra sin samlade verksamhet. Eller var det egentligen en koncernkultur som växte fram?

Railways are vital for climate mitigation as a low-carbon mode of transport but must also be resilient to climate change impacts. This study explores dynamic adaptation strategies for coastal railway infrastructure in Sweden, focusing on Trelleborg. Stakeholder workshops informed adaptation pathways using a Dynamic Adaptive Pathways Planning Light (DAPP)-light approach, which enhances stakeholder

Although a great variety of strategies to suppress Li dendrite have been proposed for lithium metal batteries (LMBs), a deeper understanding of the factors playing a crucial role during extended electrochemical cycling is often lacking. Herein, the morphological reversibility of the Li-based anode for next-generation batteries under three prevalent strategies, i.e., the use of Li-Al alloys, polyme

This paper addresses the path-tracking problem of time-optimal trajectories under model uncertainties, by proposing a real-time predictive scaling algorithm. The algorithm is formulated as a convex optimization problem, designed to balance the trade-off between improving feasibility and time optimality of a trajectory. The predicted trajectory is scaled based on the presence of path segments that

Early designs are often based on rough estimations and assumptions. Such is also the case when designing space turbines that power rocket engine fuel pumps which generally have obscure performance and size requirements. Often times, this leads to unique, single-use designs. This complicates and restricts the amount of possible testing. To aid in this early design process and to help predict turbin

Bakgrund: Psykisk ohälsa ökar i Sverige och alternativa behandlingsmetoder efterfrågas alltmer. Dock är evidensen bristfällig och trots att hästunderstödd rehabilitering är en aktivitetsbaserad rehabiliteringsform är arbetsterapeutisk forskning inom området nästintill obefintlig. Syfte: Att granska befintlig evidens avseende hästunderstödd rehabilitering för personer med psykisk ohälsa, med stöd a

Digitaliseringen har medfört en förändring av näringslivet och hur information sprids. Detta har medfört förändringar i informationssystemsmiljön som anställda arbetar i. Detta har i sint tur gjort information mer tillgänglig samt ökat mängden. Resultatet av detta har blivit att anställda har mer information som måste bearbetas, men förutsättningarna för det är densamma som tidigare. Mobila enhete
