21. Points on Production : Taphonomic research on Mesolithic osseous assemblages in Sweden
Sammanfattning : Osteoarchaeological materials are influenced by many consecutive factors, from human hunting strategies, consumption patterns and waste disposal to mechanical and chemical changes in bone structure and shape. Here Mesolithic osteoarchaeological patterns have been examined in relation to the production of bone and antler artefacts. LÄS MER

23. Large-Scale Graphene Production for Environmentally Friendly and Low-Cost Energy Storage : Production, Coating, and Applications
Sammanfattning : There is great demand for energy-efficient, environmentally sustainable, and cost-effective electrical energy storage devices. One important aspect of this demand is the need for automotive electrification to achieve more energy-efficient transportation at a reasonable cost, thus supporting a fossil-fuel free society.

24. Production Ergonomics: Identifying and managing risk in the design of high performance work systems
Sammanfattning : Poor ergonomics in production systems can compromise performance and cause musculoskeletal disorders (MSDs), which pose a huge cost to society, companies, and afflicted individuals. This thesis presents a research trajectory through the problem space by: 1) Identifying and quantifying workplace risk factors for MSDs, 2) Identifying how these risks may relate to production strategies, and 3) Developing an approach to integrating ergonomics into a companies’ regular development work.

25. Disruption Analysis - An Important Tool in Lean Production
Sammanfattning : This thesis is divided in two parts which are strongly connected. Part one deal with disruptions occurring in connection with machine down-time, quality losses and increased cycle time. The analysis is based on 10 studies, in which down-time losses in Swedish industry have been registered. LÄS MER
