1. Reliability and Life Cycle Cost Modelling of Mining Drilling Rigs
Abstract : In the context of mining, drilling is the process of making holes in the face and walls of underground mine rooms, to prepare those rooms for the subsequent operation, which is the charging process. Due to the nature of the task, drilling incurs a high number of drilling rig failures. READ MORE

2. Methods for availability improvements of a scaling machine system
Abstract : Scaling is the process of cleaning loose material from the roof, face and wall of the mine room in underground mining. The purpose of scaling is to make the mine room safe for the next operation. Due to the nature of the task, scaling has been identified as an operation with a high number of accident occurrences.

4. Set-up based operator training method in automated manufacturing: A joint production engineering and competence theory approach
Abstract : Productivity improvement strategies such as increased automation, implementation of work cells and introduction of flexible work organisations have changed the content of operator work and the preconditions for training manufacturing competence. Traditional industrial training approaches have become increasingly obsolete. READ MORE

5. Data Driven Condition Monitoring for Transmission and Axles
Abstract : As the requirements to improve up-time and thus to reduce costly down-time con-tinuously increases, the construction equipment business focuses on more and newways to increase ability and sensitivity of early fault detection of critical compo-nents and parts in order to prevent failure. Failure of critical components in theheavy duty machine may lead to unnecessary stops and expensive downtime. READ MORE
