Hur lokal bioenergi kan bidra till att Uppsala kommun når klimatmålet 2050
The purpose of this thesis was to examine how locally produced bioenergy may contribute to meet the climate target year 2050 in the municipality of Uppsala. The
goal of reduced GHG-emissions from current 6,8 ton CO2-equivalents to 0,5 ton CO2-equivalents per capita and year, year 2050 is based on avoiding harmful penalties
of an increased level of GHG in the atmosphere. By estimating available biomass in the county together with examining future technologies and emission factors for the substrates used, four possible future scenarios has been developed focusing either on electricity generation or production of biofuels. GHG-emissions of year 2050 have been calculated using the software LEAP.
The conclusion is that bioenergy, depending on how it is integrated in the energy system, may reduce greenhouse gas emissions between 0.6 ton CO2-equivalents and 1.4 ton CO2-equivalents per capita or 12% to 25% compared to 5.5 ton CO2-equivalents in the reference scenario 2050. The greatest reduction is obtained if biofuels are produced in combination with energy efficient heat requirements in
buildings..
Betydelsen av utfodring under sintiden, sintidens längd och kalvningsintervallet med avseende på kons hälsa under kommande laktation
This essay describes and compares the extensive reindeer management to the more intensive, but grazing based, sheep management system in Sweden. Differences and similarities between the two production systems will be investigated by elucidating the economy, land use and possibilities to influence production and economy through breeding, feeding and product development. The reindeer management area covers the northern part of Sweden whilst the sheep management is dispersed over the country. Both reindeer and sheep are ruminants and have relatively high demands on the quality and digestibility of the feed however reindeers graze on mountain-and forest lands whilst sheep often graze inaccessible areas or cultivated grasslands. Selection intensity is generally lower in the reindeer management compared to the intensity in sheep breeding.
Frånluftsvärmepumpens möjligheter i flerbostadshus
If a building is heated by a heat pump, it is of high importance that the heat pump has a high coefficient of performance. An exhaust air heat pump extracts heat from the building?s exhaust air. The air has a relatively high and constant temperature all year around, leading to a high seasonal coefficient of performance. This thesis examines whether it is profitable to complement an exhaust ventilation system with an exhaust air heat pump in an apartment block that already has geothermal heat pump, district heating, oil- or biofuel heated system.
Adaptive QoS Management in Dynamically Reconfigurable Real-Time Databases
During the last years the need for real-time database services has increased due to the growing number of data-intensive applications needing to enforce real-time constraints. The COMponent-based Embedded real-Time database (COMET) is a real-time database developed to meet these demands. COMET is developed using the AspeCtual COmponent-based Real-time system Development (ACCORD) design method, and consists of a number of components and aspects, which can be composed into a number of different configurations depending on system demands, e.g., Quality of Service (QoS) management can be used in unpredictable environments. In embedded systems with requirementson high up-time it may not be possible to temporarily shut down the system for reconfiguration. Instead it is desirable to enable dynamic reconfiguration of the system, exchanging components during run-time.
Styrningen av den svenska förskolan
In this study we have focused on the operational management of the public pre-school in Sweden. We have studied how the governance system is designed, why it is designed this way and what impact it has on the operational management. This has been analyzed from a theory stating that there are two types of organizations: pay-driven and function-driven. Through a case and document study we came to the conclusion that the pre-school is a function-driven organization but is nowadays acting on a market and have adopted characteristics of a pay-driven organization. We connect this change to the phenomenon New Public Management.
Alice Springs drivet av solenergi - En jämförelse mellan solceller och Stirlingsystem
In the middle of Australia there is a city called Alice Springs. The city has one of the highest amounts of daily sunshine hours and sun irradiation in the world. The Australian Government runs a project called Solar Cities, and Alice Springs is one of the participators. The main part of the goal with the Solar Cities project is to increase the amount of electricity generated by solar power and by doing that lower the impact on the environment. This thesis examines the possibilities for construction of a large scale solar power plant in Alice Springs. This is done to determine the potential of creating a more sustainable energy system in the city.

Påverkan mellan ekonomistyrningen och inköpsfunktionen : En studie av Sandvik och Scania
AbstractTitle:The Impact of Management Control Systems on the Purchaser Function - A study of Scania and Sandvik Authors: Mohammad Reza Akhbari and Johanna Sullivan Svensson Published: 2011 Keywords: Management control, purchasing function, impact, control, control instruments, Key Performance Indicators, measurement, communication and organizational structure. Background and problem formulation: In order for a company?s business idea or vision to be fulfilled, the management of a company needs assistance from various means to intentionally affect the operation in the desired direction. Management control concerns activities of both financial and non-financial character in order to implement the strategy of a company and to reach profitability. Since the purchaser function is responsible of spending 50 percent of a company?s total revenue, the function has an optimal starting point to be a key actor in the shaping and execution of a company?s strategic plan.
Webbaserad schemaläggning av läkare : Systembeskrivning och gränssnittsförslag
Through analysis of the work of scheduling the doctors at the hospitals of Sundsvall,Gävle and Karolinska in Stockholm this thesis presents some conclusion about howand why a computer system would benefit these very tasks. The reason for doing thisis mainly to save money through more efficient scheduling, but also to minimizeerrors and maximize comfort for scheduler and doctor alike.Scheduling consists of collecting doctors? requests, assessing the need of staff,distribute the available doctors and make sure all tasks are covered throughout thescheduled period of time. The work is often very complex and involves manyvariables ranging from competence to personal whishes and economical constraints.Solving these problems takes a lot of time and energy which could be better spentcuring patients.The conclusion of this thesis is that there is reason to develop such a system to savetime and optimize resources. A description of the system is found in numerous lists ofroles, tasks and prototype sketches which combined shape the content andfunctionality.
Content Management Systems - effektiviserar informationshanteringen?
För ett par år sedan tog utvecklingen och fokuseringen kring Internet fart på
allvar ute bland företag. Alla skulle ha en webbsida och anledningen till detta
var ofta att konkurrenten hade en eller att man bara ville synas.
Idag finns det ett antal så kallade Content Management System utvecklade för
att hantera information på Internet, intranet och extranet. Det gemensamma för
dessa system är att användarna skall kunna uppdatera, vidareutveckla och
administrera lösningen utan någon teknisk kompetens.
Syftet med den här uppsatsen var att undersöka om ett Content Management System
effektiviserar uppdateringen av information, med hjälp av kategorier inom
användbarhet. Användbarhet består av flera olika kategorier, dock har vi valt
att begränsa oss till tre av dessa; effektivitet, syfte och tillfredsställelse.
För att få djupare kunskaper inom ämnet användbarhet har vi läst böcker och
artiklar, vi har även sökt information via Internet. Vi hittade information om
användbarhetstest där vi fann en metod som hette utredning.
En kvalitetsanalys av EU:s direktiv om förnybar energi
There's no doubt today that mankind has contributed to the changing climate byher use of fossil fuels. This must change in the nearby future. The Europeanleaders are expressing concern that renewable energy sources are not beingused to their full potential. The 2001/77/EC Directive on Electricity Productionfrom Renewable Energy Sources was accepted in 2001 to encourage thedevelopment of energy production from renewable sources, which isconsidered a step towards the fulfillment of the goal of the Union, that 12% ofthe gross energy consumption should come from renewable energy sources bythe year 2010.The objective of this thesis is to illuminate the common legislation of the EUregarding renewable energy with regard to goal fulfillment, judicial quality,conflicts with other goals of the EU and other faults. The objective is reachedby a hermeneutic study in which interpretation of written text is the mainmethod.
Strukturerat lärande genom Action Design Research. En studie om visualisering av behörigheter
As organizations are generating more business intelligence in their systems, more employees need access those systems. As a result some sort of permission management needs to be implemented to ensure the information remain safe. Access Control Matrix (ACM) is one way of managing permissions and is widely used among organizations. The issues that comes with ACM is that the matrix itself gets difficult to manage and overview as its complexity increases with the number of permissions. The study utilizes Action Design Research to develop a tool for visualizing permissions.
