Partnering in the Dynamic Environment: The Role of Trust in Asymmetric Technology Partnership Formation
(Lappeenranta University of Technology, 2002-03-27)
The purpose of this study was to increase the understanding of the role and nature of trust in asymmetric technology partnership formation. In the knowledge-based "learning race" knowledge is considered as a primary ...
Data-parallel computation in parallel and distributed environments
(2002)
The past few decades have seen a considerable increase in the number of parallel and distributed systems. With the development of more complex applications, the need for more powerful systems has emerged and various parallel ...
The Influence of Process Conditions on the Deresination Efficiency in Mechanical Pulp Washing
(2002-06-07)
The aim of this thesis was to produce information for the estimation of the flow balance of wood resin in mechanical pulping and to demonstrate the possibilities for improving the efficiency of deresination in practice.

Automated formulation of optimisation models for steel beam structures
(2002-12-13)
Over 70% of the total costs of an end product are consequences of decisions that are made during the design process. A search for optimal cross-sections will often have only a marginal effect on the amount of material used ...
Modeling of non-isothermalvapor membrane separation with thermodynamic models and generalized mass transfer equations
(2002-05-30)
A rigorous unit operation model is developed for vapor membrane separation. The new model is able to describe temperature, pressure, and concentration dependent permeation as wellreal fluid effects in vapor and gas separation ...
Logging residues from regeneration fellings for biofuel production - a GIS-based availability and supply cost analysis
(2002-11-16)
Finland has large forest fuel resources. However, the use of forest fuels for energy production has been low, except for small-scale use in heating. According to national action plans and programs related to wood energy ...
Influence of stationary phase and eluent properties on chromatographic separation of carbohydrates
(2002-12-13)
In this thesis, the sorption and elastic properties of the cation-exchange resins were studied to explain the liquid chromatographic separation of carbohydrates. Na+, Ca2+ and La3+ form strong poly(styrene-co-divinylbenzene) ...
Local and Global Feature Extraction for Invariant Object Recognition
(2002-12-05)
Perceiving the world visually is a basic act for humans, but for computers it is still an unsolved problem. The variability present innatural environments is an obstacle for effective computer vision. The goal of invariant ...
Permanent magnet synchronous motor for industrial inverter applications - analysis and design
(2002-11-22)
During the latest few years the need for new motor types has grown, since both high efficiency and an accurate dynamic performance are demanded in industrial applications. For this reason, new effective control systems ...
Introducing massively parallel computers into operational weather forecasting
(2002-12-20)
Numerical weather prediction and climate simulation have been among the computationally most demanding applications of high performance computing eversince they were started in the 1950's. Since the 1980's, the most powerful ...
