1. Construction site productivity measurements : selection, application and evaluation of methods and measures
Sammanfattning : A construction company consists of a number of different sites where the physical production is taking place. This production is not always performed in the best possible way. There are numerous things such as organisation, logistics, co-ordination, technique, quality and others that can be improved. LÄS MER
2. Quantifying Operability of Working Machines
Sammanfattning : In working machines the human operator is essential for the performance of the total system. Productivity and energy efficiency are both dependent not only on inherent machine properties and working place conditions, but also on how the operator manoeuvres the machine. LÄS MER
3. Suspension design for off-road construction machines
Sammanfattning : Construction machines, also referred to as engineering vehicles or earth movers, are used in a variety of tasks related to infrastructure development and material handling. While modern construction machines represent a high level of sophistication in several areas, their suspension systems are generally rudimentary or even nonexistent. LÄS MER
4. On Machine Learning-Based Control for Energy Management in Construction Machines
Sammanfattning : High energy efficiency is a key requirement for modern construction machinery. This is because of stricter environmental targets, electrification, and reduction of operation costs. LÄS MER
5. Ghosts and machines : regularized variational methods for interactive simulations of multibodies with dry frictional contacts
Sammanfattning : A time-discrete formulation of the variational principle of mechanics is used to provide a consistent theoretical framework for the construction and analysis of low order integration methods. These are applied to mechanical systems subject to mixed constraints and dry frictional contacts and impacts---machines. LÄS MER
