Coping with Technology: A Study on Economic Methodology and Strategic Management of Technology
(1995-12-08)
There is a broad consensus among economists that technologicalchange has been a major contributor to the productivity growth and, hence, to the growth of the material welfare in western industrialized countries at least ...
Offdesign operation of kraft recovery boiler
(Lappeenranta University of Technology, 1993-10-01)
A model to solve heat and mass balances during the offdesign load calculations was created. These equations are complex and nonlinear. The main new ideas used in the created offdesign model of a kraft recovery boiler are ...
On the Application of Beam on Elastic Foundation Theory to the Analysis of Stiffened Plate Strips
(Lappeenranta University of Technology, 1999-10-08)
The main objective of this thesis is to show that plate strips subjected to transverse line loads can be analysed by using the beam on elastic foundation (BEF) approach. It is shown that the elastic behaviour of both the ...
Position sensorless electrically excited synchronous motor drive for industrial use based on direct flux linkage and torque control
(Lappeenranta University of Technology, 1999-04-16)
Synchronous machines with an AC converter are used mainly in large drives, for example in ship propulsion drives as well as in rolling mill drives in steel industry. These motors are used because of their high efficiency, ...
Salient Pole Synchronous Machine Modelling in an Industrial Direct Torque Controlled Drive Application
(Lappeenranta University of Technology, 1999-03-26)
Synchronous motors are used mainly in large drives, for example in ship propulsion systems and in steel factories' rolling mills because of their high efficiency, high overload capacity and good performance in the field ...
Role of references in international industrial marketing : a theory-building case study about supplier’s processes of utilizing references
(Lappeenranta University of Technology, 1997-12-16)
Scientific studies regarding specifically references do not seem to exist. However, the utilization of references is an important practice for many companies involved in industrial marketing. The purpose of the study is ...
Electrochemical Characterisation of Filter Media Properties and Their Exploitation in Enhanced Filtration
(1998-10-30)
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, ...
