Computer Modelling of the Influence of Surface Topography on Water Repellency and a Study on Hydrophobic Paper Surfaces with Partly Controlled Roughness
A computer model based on minimization of the free energy, capable to predict contact angles and spreading transitions between Wenzel and Cassie mode for drops placed on surfaces with different topography were implemented in matlab. Simulations were compared with experiments documented in the literature. These showed that reported transitions between Cassie and Wenzel mode can be explained by minimization of the free energy. In this report, a study on the possibility of constructing water repellent paper surfaces with a combination of treatment with octadecyltrichlorosilane and topography changes, is included..
Distributed Operations : En förmåga eller en metod?
Uppsatsen behandlar det amerikanska konceptet Distributed Operations (DO) kopplat mot den svenska doktrinutvecklingen. Uppsatsen bygger på Mika Ihalainens uppsats om DO som en framtida upprorsbekämpningsmetod. Uppsatsen avser fortsätta på Mika Ihalainens uppsats, och då främst med hans egna förslag på vidare forskning. Syftet med uppsatsen är att besvara frågeställningen ?Är Distributed Operations en förmåga eller en metod utifrån hur konceptet nyttjades under Falklandskriget?? och att ge ett konceptexempel på hur den svenska Försvarsmakten kan hantera en lågtek-nologisk fiende samt bidraga till den svenska doktrinutvecklingen, framförallt genom en definition av begreppen förmåga och metod.
GIS-modellering av habitat för vitryggig hackspett (Dendrocopos leucotos) som hjälpmedel i naturvårdsplanering på landskapsnivå :
The white-backed woodpecker is a forest bird being critically endangered in Sweden. The species is dependent on older forests rich in deciduous trees and dead wood. The main problem for the survival of this species is present shortage of habitat. Conservation work on this umbrella species is at present focused on finding remaining or emerging habitat networks. Large areas are scrutinized in search for suitable habitats to be protected or managed for the species sake.
Deadwood in piles or distributed : does it make any difference to saproxylic beetles?
Piles of deadwood are often retained in forests after management to support the biodiversity ofsaproxylic organisms which depend on deadwood to survive. Any knowledge about the crucial role ofpiles as suitable habitat of saproxylic organisms compared to single distributed deadwood objects thatare around the piles would help conservation actors to motivate more forest owners to supportsaproxylic organisms during their management. Therefore to give facts to this the saproxylic fauna ofdifferent pile positions (up and low) was studied and compared to distributed deadwood samplesaround each pile. Our study was focused on saproxylic beetles. Some other parameters such asdiameter, deadwood volume, pile volume and decay stage were assessed to define any effect.
Kvarnkretssimulering för test av styrsystem
This thesis has been carried out in autumn 2009 at Uppsala University for Boliden Mineral AB. Physical modelling has been used to model a comminution circuit. The model has then been linked to a PLC.When a concentrator is about to become operational Boliden Mineral AB have been looking for a way to test the PLC. The purpose of this report has therefore been to develop models for the subprocess in a concentrator and link these models to the PLC. The subprocess was a comminution circuit in Aitik36.
Den trådlösa massan - svärmbeteende och kollektiv handling
This essay seeks to analyze the consequences of modern information and communication technology for collective action within the framework of social movements. With references to the protests in Seattle 1999, the essay argues that the emergence of distributed collective action is closely related to the use of technology, for example cell phones and Internet. This distributed collective action can be characterized by its decentralized and self-organizing features, forming a global pattern emerging from local interactions. Whereas contemporary theories of collective action can be ´stretched´ to fit these aspects, they lack analytical tools to describe and analyze such systems. Further, their rejection of classical crowd theory is problematic, since it contains valuable insights.

Pedagogistans pedagogiska ledarskap
The pedagogista is a new professional role in Swedish preschools. Some people question the role, which originates from Italy, since it is believed to carry out a pedagogical leadership that belongs to the head of the preschool according to the curriculum and the Education Act. Consequently, there is cause for examining what pedagogical leadership means in an organization with a pedagogista. However, re- search has shown the success of distributed leadership within schools. Hence, it ?s interesting to find out whether the pedagogical leadership of the pedagogista could be understood as distributed leadership and what that would implicate.The purpose of this thesis is to explain and understand the pedagogical leadership of the pedagogista.
Modellbygge och regulatordesign av tröghetsmomentsimulator tillreferenssystem för stridsvagn 122
This master thesis holds a modelling in Simulink for a physical model of a main battletank tower, a three-phase induction motor and some mechanics. The aim of this work is to connect an earlier project at AerotechTelub, named StabSim to another called Eldris. In StabSim it has been made a Simulink model of the align and stabilisation system in a main battle tank 122 and in Eldris it has been build a physical model of a main battle tank tower. In this thesis the models that differs between Eldris and a real tower is changed in StabSim, and the parts that only exist in Eldris is added, for example a torque generating system which purpose is to make the model to behave like a real tower in control application, although it only has half the inertia as a real tower. The thesis even includes proposing a calculation of the torque that the torque generating system will actuate at the model..
Kadmium i skånska vattendrag : en metodstudie i föroreningsmodellering
Modelling of pollutants is commonly used in research and at departments working with environmental issues. The need to use large amounts of data when modelling creates the opportunity for more generalised models with lower data demands. Aggregating functions into coarser elements is a sort of generalisation of actual features in nature.A development of a method and a modelling tool called ?KadmiumKalkylatorn? has been performed to model cadmium pollution in rivers in Skåne, Sweden. The water runoff has been multiplied with cadmium standard concentrations based on membership in landuse classes.
Den svenska biblioteksersättningen ur författarnas perspektiv
rspective [123][pdf.gif] The aim of this thesis is to study the Swedish Public Lending Right PLR from the authors perspective. I investigate what the Swedish authors of today think about the system for distributing the money in the Authors trust Författarfonden, and in what ways they want to change it. I also try to distinguish the authors thoughts about how the scolarships from the Authors trust are distributed. What kind of authors do they think are favoured when the money is distributed and what kind of authors are treated unfairly. Finally I investigate how the money is shared out in reality by using some of the literature sociologist Johan Svedjedals theories of the distribution, and compare these facts with the authors thoughts about how the money is distributed.
Generella riktlinjer vid distribuerad Scrum
Today many companies are global and can exist all over the world. It is more common that projects are conducted in different locations, from various cities in a country to nations in different parts of the world. To manage projects both traditional practices such as the Waterfall method and new flexible methods known as agile methods are used. How is the process affected when a project is distributed, when the team is scattered in different places? This makes it difficult to create a good project, something we will discuss and try to find solutions for.
Presentationsbroschyr för livsstilsmagasin
The purpose of this essay is to present a thesis work that has been executed during a period of 10 weeks, as part of a bachelor degree in Graphic Design and Communication and also to present what has led to the design of a sales brochure for the freely distributed lifestyle magazine LKPG. The purpose of the thesis work was to examine the answers to the questions ?What does clients and local company owners want to achieve from their advertising in newspapers and magazines?? and ?How should a sales brochure for a freely distributed lifestyle magazine be designed to be at most advantage and out of most interest to its clients??. The work has been carried out through an competitors analysis, qualitative interviews, literature studies and a survey on the target group. The findings of the work are that the market of freely distributed magazines, both nationally and locally, is extremely wide and has many similar competitors.
Avbördningskapacitet för Traryd kraftverk: en modellstudie vid dimensionerande flöde
Sydkraft Vattenkraft AB owns and operates the Traryd hydropower plant, located in the river Lagan in the southern part of Sweden. The gravity dam is classed according to RIDAS guidelines (Hydropower Industry Dam Safety Guidelines) as a class 1B dam. This means that the dam must discharge a class 1-flow which has a return period of 10 000 years. The inflow into the dam has been calculated in an earlier report to 495 m3/s, with a waterline at an elevation of 126, 3 meters above sea level. The gravity dam has a discharge system with two rectangular weirs, which results in a smaller discharge than the necessary 495 m3/s.
Säkra kommunikationskanaler i en distribuerad heterogen miljö
The systems environments of today are often distributed and heterogeneous. These kind of systems have several advantages but also disadvantages. One problem is how to keep them secure.The security problems in these environments are mainly due to the communication between the connected computers. It is relatively easy to tap these communication channels from information. There is also a need for the possibility to secure these channels from modification of sent information and to be able to verify the sender and receiver of information in a secure manner.
