Följande rapport behandlar konstruktionen av ett system som kontinuerligt ska analysera kvaliteten på vatten. Systemet är uppdelat i mätenheter som utför själva mätningen och en centraliserad server som man kan koppla upp sig mot för att övervaka/justera sina mätenheter.Uppdragsgivaren till projektet var forskare från IFM på Linköpings universitet. De hade sedan tidigare ett fungerande system för att analysera vatten kontinuerligt. Vår uppgift var att ersätta deras system med ett nytt, som var baserat på mindre och billigare hårdvara. Vi har visat att systemet går att implementera på den önskade hårdvaran.Rapporten skildrar även hur projektgruppen tog designbeslut under utvecklingsfasen.

Modelica is a multi-domain and equation-based modeling language. Modelica is based on object-oriented principles and non-causal modeling. The language is constructed to facilitate reuse and decompose models. The models and the modellibrary can modified to design a new nonlinear components.Object-oriented modeling is an excellent way to analyze and study large complex heterogeneous physical systems. The object-oriented modeling approach build on reusing and decomposition of models and non-causal modeling.Modeling physical systems often leads to a DAE system with index 2 or 3.

System specialists and technicians will use the prototype. The Simulator should give the user a technical demonstration on how components work in a door system. The proto- type consists of motor, switch, relay and sensor.

Den här uppsatsen behandlar Holmes Rolston IIIs bok ?Environmental Ethics? och den teori som författaren där för fram angående naturens värde. Syftet är att klargöra hur naturen är värdefull enligt Rolston samt att kritiskt granska de argument som förs fram.Uppsatsen har tre delar. En introduktion som i korthet presenterar teorier om etisk naturalism, antropocentrisk etik, det naturalistiska misstaget, intrinsikala värden samt distinktionen mellan kultur och natur. Detta syftar till att placera den kommande diskussionen i en tydlig kontext.Efter introduktionen följer del ett, som behandlar Rolstons teori.

The European Union's Corporate Sustainability Reporting Directive (CSRD) aims toenhance and standardize sustainability reporting to support the green transition. While the public sector is expected to lead in sustainability, the application of CSRD within Swedish municipalities is fragmented. Many municipally owned companies fall below reporting thresholds individually, creating a transparency gap despite the municipal group often exceeding these thresholds collectively. This discrepancy raises moral and strategic questions regarding public accountability and the effective utilization of the framework. This thesis investigates the rationale for the proactive adoption of CSRD principles bySwedish municipalities, irrespective of formal legal requirements.

The research within the management control systems-field and more specifically performance management has been rather shallow and not much has happened the last decades besides the balanced scorecard. The researchers see a lack of studies focusing on the effects of an integrated performance management system and also how it affects the different hierarchical levels and the tasks to perform.We decided to perform an essay with case study-characteristics by looking at both the strategic and tactical level at Volvo Group, or more specifically Group Trucks. We performed three different interviews, one at the group level and two at the division level. The aim was to see what effect an integrated performance management system had on the tactical level (i.e. the divisions).Our findings and corresponding analysis suggested that Volvo was a rather centralized company in order to get the performance management system to work by enabling a ?weekly control?.

The heating of companies premises is today functional with electrical heating and heating offossil fuel. The energy cost for these kinds of heating in buildings has heavily increased duringthe last years and the influence on the environment has become more visual. This leads to thatenterprises today become more anxious to render energy more effective and find alternativesolutions to their ancient heating systems. This is something that Skandinaviska kraftprodukterAB in Halmstad has become aware of.The purpose with this examination is to find the most cost-efficient and environmental measuresfor the office and workshop premises of SKP AB. Where one of the bigger things is to find agood alternative for their current oil furnace, which was heating the workshop.

Toxic metals contaminate soil worldwide and thus serve as sever environmental threat. Therefore the purposes of this study were to investigate in which soil fractions that different heavy metals (Fe, As, Cu, Zn and Pb) could be found in contaminated soils and if it is possible to use sieving as a method for decontamination. Soil samples were collected from three different locations, the Nasa silver mine, the Blaiken-mine and Svalget environmental station. The samples were oven dried and later on sieved into six different fractions 8mm, 4 mm, 0.5 mm, 0.250mm, 0.063 mm and <0.063 mm. The fractions 4 mm, 0.5 mm and <0.063 mm from each location were analyzed in an x-ray fluorescence detector.

The first aim of this thesis is to descriptively identify and chart the activities of the strategic intelligence and environmental scanning that take place at the regional collaboration network Regionförbundet Örebro. This identification is essential in reaching the comprehensive and primary aim of the thesis: to discuss, through normative discourse, what the options of improvement are and in which ways systematic operations can be integrating parts in the organization. In order to offer guidance of development from the perspectives of environmental scanning, the question at issue has emanated from activities concerning the present methods of working at Regionförbundet Örebro.During the creation of this thesis, several interviews have been made with people who are regarded to be key roles within the regional collaboration network. An analysis has been made, based on governing documents and answers from the interviews, where possible improvements of the business have been identified. The inferences become parts of a greater potential of amelioration since they are presented as active solutions and proposals that can be directly adaptable to the organization.Our proposals of improvements/ameliorations are constituted by a number of concrete/explicit points such as: a wider public information supply and an introduction of several annual routines and methods..

Vid affärssystembyten väljs ibland standardsystem framför egenutvecklade system. En orsak är att egenutvecklade system är dyra och komplicerade att bygga. Flera företag tycker också att det är smidigare att implementera standardsystem då dessa är utformade som en paketlösning där samtliga moduler är integrerade.Ett problem för företag är att välja "rätt" standardsystem. Ett arbetsmål i denna uppsats är att ta reda på i hur stor utsträckning företag använder sig av en metod i anskaffningsprocessen. Huvudfokus är att ta reda på vad företag tycker är viktigast att anpassa - verksamhet eller system? Ett annat delmål är att titta på hur företagskulturen förändras vid ett standardsysteminförande.I undersökningen görs sex företagsintervjuer hos företag som alla har anskaffat standardsystem.

Abstract The purpose of this essay is to find difficulties and risks in the re-engineering process when restructuring to Model-View-Controller (MVC). A thoroughly theory study has been conducted to be able to understand the important steps in the re-engineering process. The methods and concepts of this essay are re-engineering, UML, system development life cycle, design patterns and MVC. The science approach used is design science where the artifact being developed are a set of models.In the analysis phase of the process the system is analyzed. The result of the analysis is notes of difficulties found and models showing the structure of the system.

This master thesis is about designing and dimensioning a boat for transport of caravan, car, trailer or ATV. Buoyancy and stability are important properties as the pontoonboat should also be able to serve as a workboat. Many of the vessels on the market today that is being used for similar purpose are stable enough, but their hull is often similar with barges and thus too slow. This work has been to construct a boat that has good stability but also has a hull that enables it to move faster, is more maneuverable and having a more attracting design than today?s barges.

Water is an important food and an important natural resource. In order to protect these are the Environmental Code and the EU directive given to water protection and related water protection regulations will be established for all water sources until 2010. Those who will prepare a water protection and related water protection regulations is the municipality or person responsible for water supply. The person then decides and declares the area as water protection and related water protection regulations are municipal or provincial government. The idea of creating a water protection is to protect the water supply and the body of water against pollution caused by point sources, diffuse sources and accidents combined.

In this paper, a navigation support approach for speech-only interaction based on auditory icons for room-based designs is presented, i.e. naturally occurring sounds that have a natural mapping to the system's underlying design metaphor. In contrast to many recent investigations that have focused on multi-modal or augmented reality systems, this paper concerns a unimodal speech and sound-only system. An auditory icon based prototype system for buildings maintenance support using a room-based metaphor was developed. The design was evaluated in a comparison with earcons and no-sound designs.
