Development a distributed simulation environment on a cluster of workstations
(Lappeenranta University of Technology, 1998-12-15)
Simulation has traditionally been used for analyzing the behavior of complex real world problems. Even though only some features of the problems are considered, simulation time tends to become quite high even for common ...
Improving the Potentials of Logistics Processes: Identification and Solutions
(Lappeenranta University of Technology, 1998-10-21)
The importance of logistics for companies is a well known and justified issue. Today, enterprises are developing their logistics processes in order to match their products and services to the requirements of the most ...
Analysis and Control of Excitation, Field Weakening and Stability in Direct Torque Controlled Electrically Excited Synchronous Motor Drives
(Lappeenranta University of Technology, 1998)
Direct torque control (DTC) is a new control method for rotating field electrical machines. DTC controls directly the motor stator flux linkage with the stator voltage, and no stator current controllers are used. With the ...
Electrochemical Characterisation of Filter Media Properties and Their Exploitation in Enhanced Filtration
Streaming potential measurements for the surface charge characterisation of different filter media types and materials were used. The equipment was developed further so that measurements could be taken along the surfaces, ...
