Market potentialfor free-cutting steels in Europe
(1999)
Työn tavoitteena oli selvittää tilannetta Euroopan automaattiteräsmarkkinoilla ja sen perusteella arvioida Imatra Steelin mahdollisuuksia kilpailla kyseessä olevilla markkinoilla. Tärkein tavoite oli kokonaismarkkinapotentiaalin ...
Design and analysis of a transversal-flux switched-reluctance-linear-machine pole-pair
(Lappeenranta University of Technology, 1999-12-18)
The Switched Reluctance technology is probably best suited for industrial low-speed or zerospeed applications where the power can be small but the torque or the force in linear movement cases might be relatively high. ...
Fouling management and retention in nanofiltration of integrated paper mill effluents
(Lappeenranta University of Technology, 1999-04-23)
Nanofiltration performance was studied with effluents from the pulp and paper industry and with model substances. The effect of filtration conditions and membrane properties on nanofiltration flux, retention, and fouling ...
Sähkökäyttöjen kaapelivärähtelyt
(1999)
Taajuudenmuuttajan kytkennän synnyttämä nopea jännitemuutos aiheuttaa
pitkään moottorikaapeliin sähköisen värähtelyilmiön. Ilmiö on
tullut erityisesti esille uusien nopeasti kytkevien puolijohdetehokytkimien
ilmestyttyä ...

Reaction Kinetics and Viscosity Modelling in the Fusion Syntheses of Ca- and Ca/Mg-resinates
(Lappeenranta University of Technology, 1999-12-18)
Rosin is a natural product from pine forests and it is used as a raw material in resinate syntheses. Resinates are polyvalent metal salts of rosin acids and especially Ca- and Ca/Mg- resinates find wide application in the ...
Merchandising Strategies and Retail Performance for Seasonal Fashion Products
(Lappeenranta Univesity of Technology, 1999-03-19)
This study presents mathematical methods for evaluation of retail performance with special regard to product sourcing strategies. Forecast accuracy, process lead time, offshore / local sourcing mix and up front / replenishment ...
Use of neural networks in robot positioning of large flexible redundant manipulators
(Lappeenranta University of Technology, 1999-10-06)
Deflection compensation of flexible boom structures in robot positioning is usually done using tables containing the magnitude of the deflection with inverse kinematics solutions of a rigid structure. The number of table ...
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, ...
