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..
Ledarskap och etik : En studie om Strukturellt etiskt klimat & Situationsbaserat etiskt beslutsfattande i fastighetsmäklarbranschen
AbstractTitle: Leadership and ethics in the Real estate agent-industry Level: Final assignment for Bachelor Degree in Business Administration Authors: Paula Massamiri & Therese Delmar Supervisor: Lars-Johan Åge, Jonas Molin & Jens Eklinder Frick Date: 2014 ? May Purpose of study: The aim of this study is to create an understanding of how leaders trough a Structural ethical climate can contribute to a Situation-based ethical decision-making of their employees. Method: We have used a qualitative method and conducted semi-structured interviews with respondents from real estate agent firms. When we studied our phenomenon, our overall research deign was qualitative interviews. Our data has been analyzed with an abductive method of analysis, influenced by Grounded theory. Results and conclusions: The study shows that leaders in the real estate agent-business trough a Structural ethical climate contributes to a Situation-based ethical decision-making of their employees by acting as role models, leads by example, highlighting the office values and rewards & punishes behaviors to control their employees? ethical decision making. Suggestions for further research: We believe that future studies can be conducted through observations to study both leaders and employees, to pay attention to employees? opinions and reflect on what affects them.
Automatiskt kabelmärkningssystem
Risk management is a key competency that is constantly being researched how it can be improved within project management. The risk management process consists of four major steps: identify risks, assess the risks? significance on the project, evaluate and address the key risks and follow up.The majority of companies seem to neglect certain identified risks, and decide not to mitigate if the risk does not cause adverse effects to the business. To counteract undesirable consequences and help organisations to become more effective at managing risks an initial work has been conducted for a risk repository.The project develops a proposal on the design of a risk repository which aim to effectively support a database implementation. The study includes literature studies which resulted in a relational model for database implementation.
A Study of the Sales Process of ERP Systems: Wasteful Management or Managing the Wasteful?
A description and analysis of the sales process of ERP systems is presented; also the consequences for the parties involved are discussed. The chosen methodological basis is an inductive research design consisting of a case study based on interviews. The analysis of the empirical data is done with a proposed analytical framework. Based on the agency theory, the analysis is tightly knitted together with opportunism. There are three controlling factors: relationships (relationship marketing), contracts (principal-agent theory), and competition.
Patogenes för prostatacarcinom hos hund : en jämförelse med människan
This thesis investigates the possibilities offered to a working landscape architect by anincreased and altered use of digital 3D environments. A basic assumption is that increased useof digital three-dimensional environments promotes the creative processes and presentationoptions of landscape architects.The thesis is based on literature studies and communication with working landscapearchitects, and includes an investigation of the visualization methods available in the Blender3D modelling software. The thesis provides a thorough survey of what it means to model inthree dimensions, as well as of what modelling methods are feasible for a landscape architectto use. As landscape architects, we work with human and unique processes, and thus it isdifficult to develop standardized and automatic software for our profession. One possiblesolution is to turn to open source development, where software and models are shared andanyone can contribute.

I skolreformernas kölvatten : Statligt kontrollbehov och synen på skolan som agent
This thesis examines the effects of the Swedish school reforms that took place in the early 1990?s. Theories such as Principal-Agent, Stewardship and Lipsky?s street-level bureaucracy are discussed as well as New Public Management (NPM). These reforms were heavily influenced by NPM, causing an increased level of street-level bureaucracy, and according to Principal-Agent theory some outcomes could have been predicted.
Brandsläckning och textil restvärdesräddning Hur saneras textil efter en pulversläckning?
This bachelor thesis discusses firefighting and the use of portable fireextinguishers in the salvageof historic artefacts focusing on textiles. It also looks into the use of multi-purpose dry chemicalextinguishers in a textile context and the impact the actual dry-agent has on textiles afterfirefighting.Literature studies, interviews and tests on different textiles were carried out to write this thesis.During the tests textiles were exposed to the dry agent and also to dry agent plus water toinvestigate the difference in residue. After vacuumcleaning it was clear that when the textile wasexposed to dry agent and water it was almost impossible to remove the chemical without rinsingin water.By examining the residue left on the textile using SEM it was possible to see if a textile was aswell decontaminated after vacuum-cleaning as it looks to the eye. We know that the dry agentoften consists of ammonium phosphate which acts corrosively on many materials and one canassume it damages textiles as well after longer exposure.Buildings housing cultural collections are vulnerable as we cannot easily replace ruined materialwith new.
Altruism i familjeföretag - effekter och åtgärder
In family firms altruistic effects can arise in order to preserve the ownership of the firm within the family. The family firm may chose to carry or take measures against these effects. Regardless, it will lead to different agent costs. Therefore, the aims of the study were to explain how altruistic effects in family firms exert an influence on the administrative systems and possible counter measures.In order to explain the origin of altruistic effects, we built a theory which showed that the altruistic effects were followed by agent costs. The family can take measures to counteract these original effects.
Utveckling av logik för handelsagent
Detta examensarbete behandlar agenter och logiken som används för att styra dessa. ESR (Experimenterande Svenska Radioamatörer) är en geografiskt spridd organisation och fysiska möten mellan medlemmarna försvåras på grund av detta. Swap Meet, som är en del av Radioträff Syd, arrangeras årligen på olika platser runt om i Sverige. Medlemmar från andra platser i landet finner det då svårt att ta sig till dessa träffar. Dessutom vill många medlemmar köpa och sälja komponenter under hela året vilket inte är möjligt i dagsläget.
I Kölvattnet av IFRS 2: En Studie av Optioner som Incitament till VD i Svenska Börsbolag
The implementation of IFRS 2 led to significant changes in the accounting practices for corporations regarding stock related compensation. The new regulations required firms to account for the stock based compensation as an expense in the financial statements, rather than merely disclosing the information in the notes section to the statements. Following prior research on the area; specifically studies made in the U.S., where researchers find that companies change their use of stock based compensation due to the increased accounted expenses, this study hypothesizes that the same pattern may be found among companies listed on the Swedish stock market. The results of this study show that the use of option incentives has decreased during the studied period 2001-2008 and that the decrease in part can be derived from IFRS 2 and in part from other factors. The results are useful to future research, as they provide an overview of the effects that IFRS 2 had on companies, and various factors that influence the behavior of corporations, as well as in a larger perspective be a factor to take into account for future modifications of the IFRS..
Vilka konsekvenser har Lex Uggla för fåmansbolag och deras ägare?: -En studie av 50 företag i Stockholm
This thesis analyzes the consequences of ?Lex Uggla? ? a law concerning the boundaries between firm and individual with respect to wealth taxation ? for small businesses, with more than 3 million SEK in over-liquidity. There are two main findings of this thesis. Firstly, the wealth taxation of non-operational assets seems to be an inefficient tax which costs the Swedish welfare system much more than it generates. Secondly, the change in actions among entrepreneurs following the extensive news coverage following the tax authority?s charges against the company of the well-known artist, Magnus Uggla (hence ?Lex Uggla?) illustrates that neither changes of rules nor new applications of rules is necessarily sufficient for an agent to change course of action.
Evolution av värden i en sokastisk tillståndsmaskin : Kan evolution underlätta för att finns lämpliga värden åt en sokastisk tillståndsmaskin hos en agent?
Evolution och tillståndsmaskiner är kända koncept inom både AI-forskning och spelindustrin. Tillståndsmaskiner har länge använts för att simulera artificella motståndare, samtidigt som evolution i många fall applicerats för att få agenter att själva upptäcka bra lösningar på problem. Arbetet använder sig av evolution för att undersöka om det går att evolvera fram bättre tillståndsövergångar i en stokastisk tillståndsmaskin än hos en fördefinierad tillståndsmaskin. Två homogena lag med två agenter vardera skapas, vilka tävlar på en arena där det går ut på att döda det andra laget först. Det ena laget delar en ständigt evolverande beteendemall medan det andra laget består av fördefinierade agenter, på så sätt att de har bedömts som duktiga på att spela spelet.

Mean value modelling of a poppet valve EGR-system
Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.
