Alfa Laval – ett företag Beyond budgeting?

Uppsatsens syfte är att beskriva och analysera hur Alfa Laval har ersatt den traditionella budgeten och hur väl den nya ekonomistyrning stämmer överens med teorierna kring Beyond budgeting. Resultatet av arbetet visar att företaget inte fullt ut har implementerat Beyond budgeting även om systemet med rullande prognoser har en stark ställning inom koncernens styrsystem. Systemet får beskrivas som en hybrid av ett stort antal system som anpassats till Alfa Lavals behov. Förändringen har resulterat i en mer framsynt organisation med ett högre tempo i beslutsfattandet och mindre politiska konflikter i planeringsprocessen

The Effectiveness of Source Code Obfuscation: an Experimental Assessment

Source code obfuscation is a protection mechanism widely used to limit the possibility of malicious reverse engineering or attack activities on a software system. Although several code obfuscation techniques and tools are available, little knowledge is available about the capability of obfuscation to reduce attackers’ efficiency, and the contexts in which such an efficiency may vary. This paper reports the outcome of two controlled experiments meant to measure the ability of subjects to understand and modify decompiled, obfuscated Java code, compared to decompiled, clear code. Results quantify to what extent code obfuscation is able to make attacks more difficult to be performed, and reveal that obfuscation can mitigate the effect of factors that can alter the likelihood of a successful attack, such as the attackers’ skill and experience, or the intrinsic characteristics of the system under attack

A Scientific Basis for the Development of the Next Generation of Biomass Burners

The kinetics derived from the classical engineering study are used to simulate the devolatilization and char burn-out phases in the CFD model. Likewise, the study on morphology development will be used to estimate suitable sub-routines, e.g. effective drag coeffcients. The full-scale campaign is used to evaluate the results of the generic CFD models. As the qualitative trends can be reproduced, the CFD models can be used to extend the experimental matrix and facilitate process optimization
