Enhancing Sustainability Through Test Point Optimization in PCBA Production Testing
No full textThis thesis explores the principles of circular economy in production test environment, aiming to enhance sustainability without sacrificing product quality. Focusing on Printed Circuit Board Assembly (PCBA) testing, the study investigates four key areas: modular and reusable Bed-of-Nails (BoN) fixture designs; dynamic power management using smart relays; alternative test methodologies; and test point optimization based on schematic analysis and historical failure data. Through a detailed review of eight commercial PCBA designs and associated yield records, the research demonstrates that approximately 30% of existing test points can be removed without diminishing diagnostic effectiveness resulting in simpler fixtures and shorter test cycles. Modular fixtures present advantages in terms of material efficiency and reusability. However, their adoption within Electronics Manufacturing Services (EMS) is limited by the high initial engineering requirements, lack of standardized interfaces, and the necessity for operator training. Although smart relay based power gating is technically implementable, it offers limited economic incentives under prevailing energy rates. Similarly, Boundary Scan and Flying Probe Testing provide valuable flexibility for small-batch and prototype testing but cannot match the throughput of optimized fixture-based methods in high-volume production. Based on the research outcomes, this thesis proposes actionable engineering strategies, including the prioritization of test points, the standardization of modular fixture designs, and the implementation of targeted power management approaches aimed at embedding circular economy concepts into end-of-line testing processes. By doing so, it advances UN Sustainable Development Goal 12.5, driving down electronic waste, preserving valuable resources, and strengthening the durability of test-system infrastructure
AI som samarbetspartner i skolledarskapet: frigörande kraft eller en förändring av skolledarskapets kärna? : En kvalitativ undersökning om skolledares upplevelser av AI:s inverkan på det mänskliga ledarskapet
No full textDenna studie är utförd av Elin Carlsson och Jonna Wennerström vid Högskolan i Halmstad, termin sex år 2025. Den ökade AI användningen i arbetslivet kan medföra förändring och omstrukturering av det samtida och framtida skolledarskapet. Därför ämnar denna studie att identifiera vilka kompetensbehov som skolledare behöver utveckla för att möta den framväxande AI-utvecklingen. Studiens avser även att undersöka skolledares inställningar kring att använda AI som en potentiell samarbetspartner i deras dagliga arbete, vilket kan medföra både möjligheter och utmaningar. Studien utgick från en kvalitativ forskningsdesign där det empiriska materialet samlades in genom semistrukturerade intervjuer.Resultaten indikerar att skolledare tenderar att föredra mänskliga samarbetspartners, på grund av AI:s upplevda begränsning i att stödja och efterlikna de “mänskliga“ aspekterna av skolledarskapet. Samtidigt framkommer en stark tro på AI som samarbetspartner i framtiden, särskilt vid avlastning av administrativa arbetsuppgifter för att kunna frigöra tid till mer värdeskapande arbete. Kombinera mänskliga förmågor med tekniska kunskaper är avgörande för att möta de nya behov som följd av AI:s ökade etablering i skolledarskapet. Studiens resultat belyser slutligen, för att AI ska kunna anta rollen som en fullvärdig samarbetspartner inom skolledarskapet, krävs det att den besitter en kontextuell förståelse, intuitiv och emotionell intelligens.This study was conducted by Elin Carlsson and Jonna Wennerström at Halmstad University during their sixth semester in 2025. The increasing use of AI in working life may lead to changes and restructuring in both contemporary and future school leadership. Therefore, this study aims to identify the competency requirements that school leaders need to develop in order to meet the emerging AI development. The study also seeks to explore school leaders’ attitudes toward using AI as a potential collaborative partner in their daily work, which may entail both opportunities and challenges. The study is based on a qualitative research design, and empirical data were collected through semi-structured interviews.The results indicate that school leaders tend to prefer human collaborators, due to AI’s perceived limitations in supporting and replicating the "human" aspects of school leadership. At the same time, there is a strong belief in AI’s potential as a future partner, especially in relieving administrative tasks to free up time for more value-creating work. Combining human abilities with technological knowledge is considered crucial for addressing the new demands that arise from the increasing integration of AI into school leadership. Finally, the results highlight that for AI to serve as a fully capable partner in school leadership, it must possess contextual understanding, as well as intuitive and emotional intelligence
Design of an Interactive Learning Module for Doppler Radar Signal Processing
No full textThis thesis discusses the development and evaluation of a real-time radar-based speed estimation system that uses the Infineon Sense2GoL Pulse radar module. The main goal was to explore Doppler-based motion detection techniques and show their educational value through organized signal processing and visualization. The system captured ten frames of raw in-phase (I) and quadrature (Q) radar echo signals from moving targets; each frame contained 256 samples. These were acquired and stored in MATLAB via serial communication. Signal processing took place frame by frame, starting with Hamming windowing to reduce spectral leakage, followed by a 512-point Fast Fourier Transform (FFT) to extract Doppler frequency components. To improve motion-specific information, low-frequency static clutter around the DC region was removed. Doppler peaks were identified using spectral thresholding, and the corresponding frequencies were converted to speed estimates using a standard Doppler equation. The system reliably detected both approaching and receding motions within the expected range of human gesture speeds. All data were visualized in MATLAB to provide a clear and educational demonstration of radar signal transformation from the time to the frequency domain. The results confirmed the reliability of the Doppler-based approach under controlled conditions and emphasized the system’s effectiveness as a teaching tool for fundamental radar signal processing concepts.Master’s thesis presented as part of the requirements for the Master’s Programme in Electronics Design, Halmstad University.</p

Newly graduated nurses emotional experiences of being new in the professional role : A general literature review
No full textBakgrund: Sjuksköterskans profession innebär att ge vård och stöd till individer för att främja hälsa och lindra lidande. Att arbeta som sjuksköterska kan vara emotionellt utmanande på olika sätt. Utbrändhet är vanligt förekommande bland sjuksköterskor. Utbrändhet är associerat med stress och hög arbetsbelastning och kan orsakas av olika faktorer som kan leda till bland annat hög personalomsättning, och den nyutexaminerade är extra sårbar. Att vara nyutexaminerad sjuksköterska innebär emotionella utmaningar under den professionella utvecklingen. Syfte: Syftet var att belysa nyutexaminerade sjuksköterskors emotionella erfarenheter av att vara ny i yrkesrollen. Metod: En allmän litteraturstudie med induktiv ansats som omfattar 10 vetenskapliga artiklar från CINAHL, PubMed och PsycInfo. Resultat: Resultatet presenteras i fem kategorier: 1) Höga förväntningar som ny sjuksköterska, 2) känslor kring den egna kompetensen i yrkesrollen, 3) stödets betydelse för emotionellt välbefinnande, 4) interaktioner och emotionella utmaningar i vårdmiljön, 5) självtvivel och känslan av att tappa kontroll. Konklusion: Nyutexaminerade sjuksköterskor genomgår emotionella utmaningar kopplat till förväntningar, kompetens, stöd, interaktioner och kontroll. Litteraturstudien kan bidra till en ökad förståelse för nyutexaminerade sjuksköterskors emotionella utmaningar bland praktiska vårdverksamheter och enhetschefer. Detta kan leda till välbefinnande och att fler sjuksköterskor väljer att stanna kvar i yrket.

Pain management in palliative care from the nurse's perspective : A general litterature review
No full textBakgrund: Palliativ vård ses som en aktiv och holistisk omvårdnad förindivider i alla åldrar med allvarligt hälsorelaterat lidande. Palliativ vårdämnar inte bota sjukdom utan att lindra lidande. God palliativ vård byggerpå fyra hörnstenar: symtomlindring, multiprofessionell samverkan,kommunikation och relationer samt stöd till anhöriga. Forskning visar attsmärtlindring är den mest bristfälliga och orättvist fördelade hälsoinsatsenglobalt. Syfte: Syftet var att belysa smärthantering i palliativ vård frånsjuksköterskans perspektiv. Metod: En allmän litteraturstudie med induktivansats där åtta kvalitativa artiklar, en artikel med mixad metod samt enkvantitativ artikel granskades och bearbetades. Resultat: Resultatetpresenterades i tre huvudkategorier som tillsammans belysersjuksköterskans perspektiv på smärthantering i palliativ vård: (1)sjuksköterskans syn på kompetens och ansvar i palliativ vård, (2)sjuksköterskans syn på samarbete och relationer i palliativ vård. Och (3)sjuksköterskans syn på kontext och vårdens ramar i palliativ vård.Konklusion: Smärthantering i palliativ vård är komplext och kräver attsjuksköterskan förenar medicinsk kompetens med ett helhetsperspektiv påpatientens lidande. Kommunikation, samarbete och kontinuerligkompetensutveckling framstår som avgörande för att uppnå trygg ochindividualiserad smärtlindring i livets slutskede.Background: Palliative care is regarded as an active and holistic form ofnursing for individuals of all ages experiencing serious health-relatedsuffering. It does not aim to cure disease but to relieve suffering. High-quality palliative care rests on four cornerstones: symptom relief,multiprofessional collaboration, communication and relationships, andsupport for family members. Research shows that pain relief is the mostdeficient and inequitably distributed healthcare intervention globally. Aim:The aim was to explore pain management in palliative care from the nurse’sperspective. Method: A general literature review based on an inductiveapproach was conducted, including eight qualitative studies, one mixed-method study, and one quantitative study. Results: The results werepresented in three main categories: (1) the nurse’s view of competence andresponsibility in palliative care, (2) the nurse’s view of collaboration andrelationships in palliative care, and (3) the nurse’s view of context andstructural conditions in palliative care. Conclusion: Pain management inpalliative care is complex and requires nurses to combine medicalcompetence with a holistic understanding of the patient’s suffering.Communication, collaboration, and continuous professional developmentare essential to achieve safe and individualized pain relief at the end of lif
