Technical and environmentally the combined heat and power plant is by today's standards among the leading waste incineration plants in the world. The owners are constantly striving to improve the efficiency of the waste incineration plant. They have seen the opportunities for savings in reducing internal usage of electricity.

For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

The different aspects of each individual construction project such as the general conditions, design and economic restrictions as well as many more factors mean it is difficult to standardize building processes or plan in detail based on past experiences. As a result operational efficiency is often reduced, and unnecessary waste is generated. To make an organization more efficient and therefore reduce waste production everybody involved needs to appreciate and understand the improvements that can increase the organization?s efficiency. To investigate these improvements a time study was performed on two different construction sites, both of which involved buildings being constructed of prefabricated steel and concrete elements.

The contact company, LRF Konsult, is a consulting firm specialized in areas of law, real estate, finance and taxation. Discussions on the subject of agricultural improvement in the area of Lean, has primarily been driven by the Royal Swedish Academy of Agriculture and Forestry, where LRF Konsult also participated. This thesis can be seen as a preliminary study of how Lean can work within agricultural enterprises.The thesis primarily focuses on the possibilities dairy farms have to improve operations. What practical benefits they can obtain through the implementation of Lean. And how an implementation could take place.By visits to two dairy companies, and through interviewing their respective business leaders, an image of the companies activity for improvement, in connection to this thesis was established.

The purpose of this thesis is to identify the factors that drive efficiency and effectiveness in technical development projects performed at A?F?s department of product development. In addition to identifying and analyzing these factors, the thesis also analyzes what needs to be taken in to account in order to implement a measurement system that is able to both monitor and control the identified factors.The thesis has been performed in a qualitative manner. It is based on interviews with people from several different technological companies, within different lines of business, all of which are customers to A?F?s department of product development.The results show that there are seven critical factors for project efficiency and effectiveness.

This thesis investigates the regulation of hybrid work environments by focusing on the implementation of rules by both management and employees. It examines the methods used to measure compliance and the consequences of non-compliance within organizations. The study also explores how flexibility in work arrangements and the balance between work and personal life affect employee well-being and productivity. Furthermore, it highlights the critical role of self-leadership in navigating the complexities of hybrid work, emphasizing how effective self-management can enhance organizational efficiency and employee satisfaction. We have adopted a qualitative research approach and interviewed employees, managers, and HR personnel with experience in hybrid work. The different perspectives are expected to provide insights into this area by including all levels within an organization It is evident that organizations that have clearly established rules and guidelines regarding hybrid work have achieved the best desired results.

With increased deployment ofintermittent renewable energy, such aswind and solar power, energy storagebecomes necessary to help reduceproduction peaks. Thermoelectric EnergyStorage is a method still in researchphase, which stores electricity in hotwater at a temperature of 120 ° C. Thisthesis aims to examine whether theThermoelectric Energy Storage would bepossible to integrate into existingpower generation such as a combined heatand power plant, and how the technologypotentially could function in theelectricity market. ThermoelectricEnergy Storage consists of a chargingprocess and a discharging process, bothoperating by the working fluid CO2. Toincrease the efficiency of theThermoelectric Energy Storage, wasteheat from the district heating networkis integrated.A model of the Thermoelectric EnergyStorage has been developed and it wascalculated by thermodynamic propertiesof the working fluid, CO2, in thevarious process steps.

The aim of this essay is, with reference to a close study on the negotiation delegations of the Tenant Association, to examine the principals of democracy in relation to distribution of power and participation, efficiency and professionalism. This is done with the intention to understand the Tenant Association's view on its own commission as negotiator, according to democracy. The investigation is carried out on the Tenant Association in the Swedish cities of Stockholm, Malmö and Gothenborg.The data acquisition was obtained by using a questionnaire and through interviews with representatives from the Tenant Association negotiation delegation.A central conclusion from this investigation is that the representatives of the Tenant Association generally are satisfied with the democracy model used in the organisation, despite awareness of the fact that there are some failures with representation amongst younger people, women and immigrants. Also, they suggest that the model with representative democracy is by all means the most useful because of its arrangement and efficiency in decision making processes.The policies of the Tenant Association, considering distribution of power and participation between elected representatives and employees, are legitimated by the negotiation delegates. However, there is obvious discrepancy in the look upon their respective tasks between the delegates and the chief negotiators.One can recognise the development of democracy that is called New Public Management in this survey.

In the spring of 2014 Sweco Systems AB were commissioned to design a ventilation system for a newly built preschool in Linköping. Terms from the client was that it cost efficiency would cope with the energy demands that are placed on the building. The unit chosen was a cross-flow heat exchanger, and this work is to compare it with two other heat exchangers to see if a more energy and cost efficient could have been chosen. The heat exchangers that was chosen for the comparison was a rotating- and a counterflow heat exchanger. Simulations have been made to the different heat exchangers by the manufacturers.

The aim of this study was to increase the knowledge about if and how the National Value System?s goal of a life with dignity for the elderly pervades the work in home care organisations. The study was based on a qualitative research method and was conducted through interviews with professional care givers in home care organisations, there were five individual interviews and one pair interview. The background for this study was the National Value System for the eldercare that was introduced in 2011. The theory of New Public Management and the concept of Rationality of Caring were used to analyse the result.

An organization that uses all of its improvement opportunities has a great advantage compared to its competitors. It is an important task when it comes to continuous improvements of every process. Up until September 2007, Husqvarna AB had a suggestion committee who evaluated every suggestion separately and the proposer received a payment if the suggestion was approved by the committee. However, this system did not work satisfying enough to fulfill Husqvarna?s needs and they are now looking for a system that can handle the ideas from the employees in a more effective way.

Making the work in the public sector more efficient is something that has been seen as necessary during the later years. One way to do this on municipal level has been to apply solutions former used mostly by private companies. The organisational parts have also been adjusted to existing conditions in this work of change. For example more and more municipalities have come to use the purchaser-supplier model since the beginning of the 1990's. Norrköping, Linköping and Motala have been chosen in this essay for a closer study of the effects of the changes of the 90's, from an efficiency point of view.
