Technology selection and group decision support systems: Case studies on supporting strategic technology selection processes
(2002)
The objective of the dissertation is to increase understanding and knowledge in the field where group decision support system (GDSS) and technology selection research overlap in the strategic sense. The purpose is to develop ...
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 ...
Development of fibre recovery process
(2002)
The fiber recovery process is an essential part of the modern paper mill. It creates the basisfor mill's internal recirculation of the most important raw materials ¿ water and fiber. It is normally also a start point for ...

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 ...
