As a core component of an ITS, CAVs have garnered significant attention and expect to play an important role in enhancing traffic safety. To enable (future) practical deployment of CAVs, safety strategies must be incorporated into the control design. This includes, in particular, strategies for ensuring avoidance or mitigation of multi-vehicle collisions. Conventional control strategies exhibit so

Denna avhandling undersöker konceptet Rolling Magnet Energy Harvester (RMEH), en kinetisk energifångare, baserad på principerna för elektromagnetisk induktion. RMEH är utformad med fraktcontainrar i åtanke och utnyttjar energin från fordonets rörelser för att driva potentiella sensorer ombord. Det långsiktiga målet är att förbättra logistiken genom att tillhandahålla en enkel, hållbar och underhålThis thesis investigates the concept of a Rolling Magnet Energy Harvester (RMEH), a kinetic energy harvester based on the principles of electromagnetic induction. Designed with shipping containers in mind, the RMEH harnesses energy from the rolling motion of vehicles to power potential onboard sensors. The long term objective is to enhance logistics by providing a simple, sustainable, and maintena

Titel: Upplevelser och erfarenheter av fantomsensationer/-smärta vid amputation i nedre extremiteten, en kvalitativ intervjustudie. Introduktion: Fantomsmärta (PLP) och fantomsensationer (PS) är vanliga fenomen som amputerade upplever. Tidigare forskning visar stor spridning angående resultat och det återfinns en begränsad representation av upplevelser och erfarenheter av personer med påverkan av

Integrating learning-based techniques, especially reinforcement learning, into robotics is promising for solving complex problems in unstructured environments. Most of the existing approaches rely on training in carefully calibrated simulators before being deployed on real robots, often without real-world fine-tuning. While effective in controlled settings, this framework falls short in applicatio

Hazardous situations involving radioactive, chemical, and other dangerous materials pose significant risks to emergency responders. In such situations, robots can support civil forces in reconnaissance and mitigation. However, this requires the development of robotic systems with novel AI-based assistance functions, operation procedures, and raises new ethical and legal questions. To address these

Trajectory planning under kinodynamic constraints is fundamental for advanced robotics applications that require dexterous, reactive, and rapid skills in complex environments. These constraints, which may represent task, safety, or actuator limitations, are essential for ensuring the proper functioning of robotic platforms and preventing unexpected behaviors. Recent advances in kinodynamic plannin

From the perspective of the Swedish education system, rural knowledge does not seem to be particularly important. Many young people in rural areas have deep and important knowledge that is invisible in school and during school time, both to teachers and to the young people themselves. This paper examines knowledge used in agriculture and animal husbandry, a type of knowledge that is particularly uFrom the perspective of the Swedish education system, rural knowledge does not seem to be particularly important. Many young people in rural areas have deep and important knowledge that is invisible in school and during school time, both to teachers and to the young people themselves.

Alternative food networks are increasingly promoted in policy, academic, and civil society discourses as pathways to sustainable and socially just food systems. However, their demographic homogeneity raises questions about their capacity to foster social inclusion. This study explores how Community Supported Agriculture (CSA) initiatives in Southern Germany navigate tensions between solidaritybase

Corporations now face dual pressures from climate change: the financial vulnerability and environmental accountability. As a response, corporate climate-related disclosure has evolved from voluntary sustainability pledges to a regulatory and market necessity in many regions including the Mainland China. This study explores climate-related disclosure behaviors and underlying motivations of Chinese

Climate change and environmental degradation are some of the most pressing crises of our time, however action is lacking. In order to create system transformation, the inner dimensions of sustainability need to be addressed: values, worldviews and qualities on an individual, collective and system level. Ecovillages seem to be spaces where the integration of internal and external sustainability occ

Glacier retreat driven by climate change has created intense water scarcity in Ladakh, India, threatening both the local agriculture and livelihoods. In response, Artificial Glaciers (AGs) have emerged as an adaptive strategy. This study examines the role of AGs in enhancing social resilience in the villages of Ursi and Igoo using the Six Attributes of Social Resilience framework. A mixed-methods

Bakgrund: Total höftplastik (THA) anses vara en effektiv behandling vid höftartros som förväntas resultera i minskad smärta och återställd funktion. Trots att många patienter får goda resultat, upplever en del en kvarstående smärta och funktionsnedsättning efter operationen. Rehabiliteringen efter THA varierar stort mellan olika vårdgivare och det finns en avsaknad av nationella riktlinjer för reh

Bakgrund: Ätstörningar, särskilt de två vanliga typerna, anorexia nervosa och bulimia nervosa, är komplexa och svårbehandlade sjukdomar med höga återfallsfrekvenser. De vanligaste behandlingarna består av psykologiska insatser och medicinering. Som en tilläggsbehandling inkluderas fysioterapeutinsatser. Anorexia nervosa och bulimia nervosa har en multifaktoriell orsak och den höga återfallsfrekven

Bakgrund: Tidigare forskning om idrottsrelaterade hjärnskakningar och rehabilitering inom innebandy och ishockey är begränsad. Eventuella skillnader mellan dessa idrotter har ännu inte undersökts. Syfte: Syftet med denna studie var att kartlägga förekomsten av idrottsrelaterade hjärnskakningar samt undersöka rehabiliteringsmetoder hos spelare i utvalda innebandy- och ishockeyföreningar i Skåne. S

Bakgrund Handartros är en mycket vanlig sjukdom som drabbar stora delar av den äldre befolkningen, varav majoriteten av de drabbade är kvinnor. Handartros kan bland annat ge symptom så som smärta, stelhet, nedsatt funktion och påverkad hälsorelaterad livskvalitet. Grundbehandlingen i Sverige för dessa symptom är information, träning och om det är relevant, viktnedgång. Få studier har dock hittills

Bakgrund: Studier har visat att regelbunden fysisk aktivitet har god effekt på sömnen. Det finns även forskning som tyder på att detta samband kan skilja sig beroende på kön och ålder. Det saknas dock studier som jämför sambandet i grupper med olika sysselsättningar. Vidare saknas det studier i en svensk kontext som undersöker sambandet, hur det skiljer sig mellan; män och kvinnor, olika åldersgru

Objective: To investigate the expression and clinical significance of DNA helicase RecQL1 in cervical carcinoma and cervical intraepithelial neoplasia(CIN). Methods: The expression of DNA helicase RecQL1 were determined with reference to clinicopathological features and patient survival. 75 cervical carcinoma, 60 CIN and 20 normal control cases were collected for immunohistochemical analysis. Resu

Unmarried childless older men in rural China represent a growing group who face distinct care situations. Support networks are essential to their health and care, yet those networks remain understudied. This study aims to investigate the support networks available to this group, how they change over time, and the factors affecting their development. Guided by a situational perspective on care, the

Objective: To investigate the expression of Pyruvate dehydrogenase kinase 1(PDK1), phosphorylated Pyruvate dehydrogenase (p-PDH) and Pyruvate kinase isozyme type M2 (PKM2) based on Warburg effect pathway in cervical cancer tissues, and explore the roles of these molecules on prognosis and recurrence after postoperative radiation. Methods: The expressions of PDK1, p-PDH and PKM2 in primary tissues
