Exploring the strategic impact of technological change - Studies on the role of Internet in magazine publishing
(2007-09-19)
Over the past few decades, turbulent change has characterized the situation in the media industry. It has been noted that digitalization and new media are strongly influencing the industry: it is changing the existing ...
Dynamic Simulations of Rotors during Drop on Retainer Bearings
(2007-11-07)
The active magnetic bearings have recently been intensively developed because of noncontact support having several advantages compared to conventional bearings. Due to improved materials, strategies of control, and electrical ...
Particle transport method for convection-diffusion-reaction problems
(2007-12-01)
Convective transport, both pure and combined with diffusion and reaction, can be observed in a wide range of physical and industrial applications, such as heat and mass transfer, crystal growth or biomechanics. The numerical ...
Supervised localimage feature detection
(2007-12-07)
This thesis is about detection of local image features. The research topic belongs to the wider area of object detection, which is a machine vision and pattern recognition problem where an object must be detected (located) ...
Towards desired crystalline product properties: In-situ monitoring of batch crystallization
(2007-08-07)
The objective of industrial crystallization is to obtain a crystalline product which has the desired crystal size distribution, mean crystal size, crystal shape, purity, polymorphic and pseudopolymorphic form. Effective ...

(2007-03-03)
The patent system was created for the purpose of promoting innovation by granting the inventors a legally defined right to exclude others in return for public disclosure. Today, patents are being applied and granted in ...
Impingement jet cooling of end windings in a high-speed electric machine
(Lappeenranta University of Technology, 2007-12-04)
The rotational speed of high-speed electric machines is over 15 000 rpm. These machines are compact in size when compared to the power rate. As a consequence, the heat fluxes are at a high level and the adequacy of cooling ...
A novel approachfor assessing the fatigue strength of ultrasonic impact treated welded structures.
(2007-12-18)
It is commonly observed that complex fabricated structures subject tofatigue loading fail at the welded joints. Some problems can be corrected by proper detail design but fatigue performance can also be improved using ...
Field Sales Management Control: Towards a Multi-Level Theory
(2007-12-07)
The purpose of this dissertation is to increase the understanding and knowledge of field sales management control systems (i.e. sales managers monitoring, directing, evaluating and rewarding activities) and their potential ...
On Modelling, System Identification and Control of Servo-Systems with a Flexible Load
(2007-06-16)
The present study was done with two different servo-systems. In the first system, a servo-hydraulic system was identified and then controlled by a fuzzy gainscheduling controller. The second servo-system, an electro-magnetic ...
