Using an Ergometer in a Controlled Underwater Environment This thesis presents the development and validation of a weight-based ergometer system for assessing diver workload under controlled and realistic swimming conditions.The aim was to design a test setup that enables divers to swim against adjustableresistance levels corresponding to standardized workload intensities. Understanding diver workload is essentialContinue reading “Elaboration and Experimental Validation of Divers Workload”

Systematic Concept Evaluation and ExperimentalValidation of a Portable Condition Monitoring Device Background. Unplanned stoppages in cableway roller systems cause significantfinancial losses and material waste in manufacturing environments like NKT inKarlskrona. Current maintenance strategies are mostly reactive or rely on manualinspections, creating a need for practical predictive maintenance solutions. Objectives. The objectives of the thesis areContinue reading “Predictive Maintenance for Cableway Rollers”

Cable Management During Transport within Production Facility This thesis addresses the issue of transporting cables attached to a pump throughout the manufacturing process, from assembly to painting and packaging, with a solution suitable for a wide range of pumps with alternating sizes, shapes, weights, and suspension systems. In order to generate a fully functional cableContinue reading “Topology Optimization as Design Support for Temporary Cable Support Holder”

For industries utilizing conveyor systems, roller failure can result in reduced efficiency or even unplanned downtime. A typical conveyor roller consists of an outer tube, end caps at both ends, bearings housed within the end caps, and a throughgoing axle. In collaboration with NKT, this thesis investigates how outdoor conveyor rollers can be improved withContinue reading “Design and Development of Durable Conveyor Rollers for Outdoor Use”

This thesis explores the design of a modular, passive attachment for small autonomous underwater vehicles (AUVs) aimed at enhancing their acoustic target strength for use in active sonar testing. Conducted in collaboration with FMV, the project addresses the limitations of current manually deployed sonar targets by proposing a cost-effective and reusable solution that preserves AUV’sContinue reading “Designing a Modular Attachment to Transform AUVs into Sonar Targets”

This Bachelor’s thesis aims to develop a robust and user-friendly GPS tracker housing for cattle. The project focuses on improving livestock management through real-time monitoring and health surveillance, aiming to enhance animal welfare and operational efficiency on farms. The project aims to design an innovative GPS housing that ensures secure attachment in a collar aroundContinue reading “Design of a GPS Tracker Housing for Cattle”

Batteritillverkare Saft AB i Oskarshamn har under det senaste året börjat en resa mot ökad automation för att bli mer konkurrenskraftiga, men även reducera repetitiva arbetsuppgifter för att förbättra ergonomin. De har arbetat fram en tydlig industriell vision som sträcker sig till år 2040. Visionen går under arbetsnamnet ”No Touch!” där målbilden är att haContinue reading “Automation av Hantering av Polbultkomplett”

Tail threading is the process of guiding a continuous sheet through multiple rollers. It is a critical step in paper, board, and textile production, especially after a break or during startup. This thesis investigates the development of improved methods for tail threading in flooring mat production, which is heavier compared to paper and textile production,Continue reading “Guiding a continuous sheet through multiple rollers”

High-frequency radar imaging using Synthetic Aperture Radar (SAR) technology has significant potential for non-destructive testing and quality control in industrial applications, such as inspecting High Voltage Direct Current (HVDC) cables during manufacturing. This thesis develops and verifies a calibration procedure designed to accurately determine the Phase Centre (PC) of an FMCW radar antenna mounted onContinue reading “High-frequency radar imaging”
