A Study on Fractionation and Ultrafiltration of Proteins with Characterized Modified and Unmodified Membranes
Membrane filtration has become increasingly attractive in the processing of both foodand biotechnological products. However, the poor selectivity of the membranes and fouling are the critical factors limiting the development ...
On the Reversed Brayton Cycle with High Speed Machinery
This work was carried out in the laboratory of Fluid Dynamics, at Lappeenranta University of Technology during the years 1991-1996. The research was a part of larger high speed technology development research. First, there ...
New Distance Transforms for Gray Level Image Compression
(Lappeenranta University of Technology, 1996-04-27)
This thesis deals with distance transforms which are a fundamental issue in image processing and computer vision. In this thesis, two new distance transforms for gray level images are presented. As a new application for ...
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 ...
Mk-factor Equations and Crack Growth Simulations for Fatigue of Fillet-welded T-joints
(Lappeenraata University of Technology, 1993-06-22)
Development a distributed simulation environment on a cluster of workstations
(Lappeenranta University of Technology, 1998-12-15)
Simulation has traditionally been used for analyzing the behavior of complex real world problems. Even though only some features of the problems are considered, simulation time tends to become quite high even for common ...
Knapsack sets for cryptography
(Lappeenraata University of Technology, 1994-05-06)
The basic goal of this study is to extend old and propose new ways to generate knapsack sets suitable for use in public key cryptography. The knapsack problem and its cryptographic use are reviewed in the introductory ...
Competitor Information andCompetitive Knowledge Management in a Large Industrial Organization
Thisthesis supplements the systematic approach to competitive intelligence and competitor analysis by introducing an information-processing perspective on management of the competitive environment and competitors therein. ...
The effects of productivity on profitability: a case study at firm level using an activity-based costing approach
Productivity and profitability are important concepts and measures describing the performance and success of a firm. We know that increase in productivity decreases the costs per unit produced and leads to better profitability. ...
Freezing Point Depressions of Dilute Solutions of Alkali Metal Chlorides and Bromides
Freezing point depressions (¿Tf) of dilute solutions of several alkali metal chlorides and bromides were calculated by means of the best activity coefficient equations. In the calculations, Hückel, Hamer and Pitzer ...
