1. Coated Ferritic Stainless Steels as Interconnects in Solid Oxide Fuel Cells - Material Development and Electrical Properties
Sammanfattning : Solid oxide fuel cells (SOFCs) are attracting increasing interest as devices with potentialuses in decentralized and clean electricity and heat production. Several challengeswith respect to materials have to be overcome to achieve efficiencies and life-spansthat are sufficient for long-term applications. LÄS MER
2. Prerequisites and Possibilities for Manufacturing Companies to Prioritize and Manage Occupational Health and Safety
Sammanfattning : Legislation demands that health and safety of humans at work must be secured. Today, far from every company has a functioning systematic management of occupational health and safety (OHS) in place to fulfill its legal obligations. Instead, other day-to-day tasks appear to have greater priority. LÄS MER
3. High dynamic stiffness nano-structured composites for vibration control : A Study of applications in joint interfaces and machining systems
Sammanfattning : Vibration control requires high dynamic stiffness in mechanical structures for a reliable performance under extreme conditions. Dynamic stiffness composes the parameters of stiffness (K) and damping (η) that are usually in a trade-off relationship. This thesis study aims to break the trade-off relationship. LÄS MER
4. Simulation-based multi-objective optimization for reconfigurable manufacturing systems : Reconfigurability, manufacturing, simulation, optimization, RMS, multi-objective, knowledge discovery
Sammanfattning : In today’s global and aggressive market system, for manufacturing companies to remain competitive, they must manufacture high-quality products that can be produced at a low cost; they also must respond efficiently to customers’ predictable and unpredictable needs and demand variations. Increasingly shortened product lifecycles, as well as product customization degrees, lead to swift changes in the market that need to be supported by capable and flexible resources able to produce faster and deliver to the market in shorter periods while maintaining a high degree of cost-efficiency.

5. Additive-Driven Improvements in Interfacial Properties and Processing of TMP-Polymer Composites
Sammanfattning : Efforts to address environmental concerns have resulted in new regulations designed to plan the reduction of plastic and synthetic polymer usage, necessitating the search for sustainable natural alternatives with comparable cost-effectiveness and mechanical performance. Thermomechanical pulp (TMP) fibres are one of the most affordable natural fibres that have no chemical refining in production, production have a high yield of 90-98% and TMP fibres have been demonstrated to improve the mechanical characteristics (strength, stiffness and toughness) of wood-polymer composites (WPCs) compared to the pure polymer.
