  2. 1. Quantifying Operability of Working Machines

    Author : Reno Filla; Jan-Ove Palmberg; Kjell Ohlsson; Jonas Larsson; Linköpings universitet; []
    Keywords : Operability; machine harmony; operator workload; control effort; simulation; operator model; human operator; working machines; construction equipment; wheel loaders; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : 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. READ MORE

  4. 2. Operator and Machine Models for Dynamic Simulation of Construction Machinery

    Author : Reno Filla; Jan-Ove Palmberg; Jonas Larsson; Allan Ericsson; Tobias C. Larsson; Linköpings universitet; []
    Keywords : dynamic simulation; construction equipment; discrete simulation; continuous simulation; operator model; driver model; integrated product development; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : VIRTUAL PROTOTYPING has been generally adopted in product development in order to minimise the traditional reliance on testing of physical prototypes. It thus constitutes a major step towards solving the conflict of actual increasing development cost and time due to increasing customer demands on one side, and the need to decrease development cost and time due to increasing competition on the other.

  5. 3. Towards Human Supervisory Control in Advanced Manufacturing Systems

    Author : Johan Stahre; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; human; CIM; case study; operator; FMS; supervisory control; method; manufacturing; model; cross-disciplinary;

    Abstract : This thesis is on the topic of Human Supervisory Control in Advanced Manufacturing Systems (AMS). Presently, these systems suffer from inferior reliability and low productivity, unless "nursed" by skilled operators. Operators controlling the AMS are approaching a work situation similar to that of operators in continuous process manufacturing. READ MORE

  6. 4. Covariate Model Building in Nonlinear Mixed Effects Models

    Author : Jakob Ribbing; E. Niclas Johnsson; Mats O. Karlsson; Janet Wade; Uppsala universitet; []
    Keywords : Pharmacokinetics Pharmacotherapy; Pharmacokinetics; Pharmacodynamics; Modeling; Covariate selection; Stepwise selection; Covariate analysis; Methodology; Model validation; Model evaluation; Type-2 diabetes; Beta-cell function; Meta analysis; Cross-validation; Least absolute shrinkage and selection operator; Pharmacometrics; ED optimization; Farmakokinetik Farmakoterapi;

    Abstract : Population pharmacokinetic-pharmacodynamic (PK-PD) models can be fitted using nonlinear mixed effects modelling (NONMEM). This is an efficient way of learning about drugs and diseases from data collected in clinical trials. READ MORE

  7. 5. The GMOC Model : Supporting Development of Systems for Human Control

    Author : Simon Tschirner; Bengt Sandblad; Anders Jansson; Sebastiaan Meijer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Human-Computer Interaction; User-Centered Design; Human Control; Train Traffic Control; Usability; System Development; Human Work; Railway Traffic; Rail Human Factors; Mental Models; Situation Awareness; Datavetenskap med inriktning mot människa-datorinteraktion; Computer Science with specialization in Human-Computer Interaction;

    Abstract : Train traffic control is a complex task in a dynamic environment. Different actors have to cooperate to meet strong requirements regarding safety, punctuality, capacity utilization, energy consumption, and more. The GMOC model has been developed and utilized in a number of studies in several different areas. READ MORE
