Ledarskap och relationer vid implementering av lean i sjukvården: en utveckling av yrkesidentiteten
The aim of this case study was to investigate the role of leadership and interpersonal relations among staff during implementation of lean at a University Hospital in Sweden. The 15 respondents were leaders and staff members from different wards and clinics, who had started working according to lean principles. One of the methods used was explorative, low structured interviews. Other methods used for gathering information about the case was attending lectures about lean healthcare at the hospital, part-taking in the lean game and reading articles about lean and the implementation in both daily press and on the intranet of the hospital. The results showed that an open and accessible leader that coaches his/her staff and supports their work, helps the staff to develop a lean identity.
Spännkraft på bandavskrapare : Utredning och konstruktion
This thesis was performed at Vendig AB which is a company that develops and sells products such as belt scrapers for conveyor. The thesis is divided into two parts, one part where it´s investigated which tension force is required to tighten Vendig AB´s scraper Hampus against the belt in a correct way. The second part is called mechanical design and here a new and more compact tension device is developed.Field studies has been conducted at a couple of Vendig AB´s costumers to get a knowledge base about how Vendig AB´s products are used, how they function and the environment they operate in. During one of the field studies the force between the scraper and the belt was measured. The result from the measurements, together with a report from LKAB [1], were evaluated and summarized in a table.
Humanitära interventioner. Europeiskt handlingsutrymme i förhållande till ett modernt interventionsbegrepp
The world is getting smaller. Global markets, political processes and communication technology bring people together. Even though many of these processes are dynamic and constructive, they have also resulted in a need for better and more effective ways of international conflict resolution.
This thesis investigates central issues connected to the concept of humanitarian interventions in relation to current and future legislation of the European Union. The overall question is whether the rapid globalization process has resulted in a change of international law towards more liberal view where authorization of the security council is not always needed? And, if there has actually been such a liberalization, how does that affect the legal possibilities for the European Union to carry out armed operations without the consent of the global community?
The conclusion of the thesis is that international law has been modified mainly in two aspects: First, the concept of sovereignty is no longer seen merely as a right of the nation, but also as a responsibility.
Utvärdering av försvarsspecifika radiovågformer
To be able to evaluate different radio waveforms in a laboratory environment FOI in Linköping has developed an experimental system for radio communication called Rasmus. The system consists of a transmitter, a channel emulator and a receiver. The transmitter modulates a digital signal to a desired analogue waveform. The channel emulator is used to simulate a real radio channel. The channel emulator distorts the signal by splitting it up in several propagation paths.
En flödesutjämnande driftstrategi för Uppsalas fjärrvärmesystem : En ändrad styrning av framtemperaturen
This thesis examines a possible control strategy to minimize flow fluctuations in Uppsala?s district heating system. High variations in flow rate may lead to complications caused by hydraulic constraints in the district heating system. These complications, such as inadequate pressure and temperature levels, increase the risk of heat delivery failures. It is therefore important to avoid such situations both for the producer and for the customers.Typically, the forward temperature is controlled by using a rough correlation with respect to the outdoor temperature.
Bland boktips och länksamlingar : En undersökning av de svenska folkbibliotekens webbplatser för ungdomar
The public libraries were quick to adapt to the changes that the Internet brought on, and today library websites are an important part of the public library. To meet the needs of teens today, the library website could offer a range of contents to make it an attractive place on many levels; both the academic needs as well as social and recreational needs should be addressed.The aim of this thesis is to evaluate public library websites for teenagers in Sweden, and to examine how well the websites address the developmental tasks and needs that teenagers have. The method used is website evaluation, one quantitative and one qualitative. A total of 60 public library sites for teenagers were evaluated, using 11 criteria based on Havighursts developmental tasks. The quantitative evaluation measured how many functions each website had per criteria, and showed that the majority of the sites had one or two functions for most of the criteria.

Concurrently important benefits have been noticed from the effects of massage, effects that can be assumed to restore individual?s health with depression and depressed mood. The aim of the study was to examine the importance of gentle massage in connection with depression and depressed mood. The research was based on scientific studies that were applied through the databases Cinahl, elin@Kristianstad, PsycARTICLES, PsycINFO, PubMed and the journal Vård i Norden as well as by manual searches.
Effektiv partiformning : analys och tillämpning på Uppåkra Mekaniska AB
This paper is the result of a case study conducted at Uppåkra Mekaniska AB during the spring of 2006. The task that was presented by Uppåkra was to develop a basis for a decision for the planning activities at the company, so that in the future they can create lot-sizes which are based upon a total cost perspective. Total cost in regards to lot-sizing is defined as the sum of the administrative reordering costs and warehousing cost per stock keeping unit.To collect data a series of interviews and observations were conducted. This data was then used during the lot-sizing simulation and analysis. The 15 units that the simulation was conducted on were grouped into three item classes depending how many different machine setups they required during the production process.
Simulering, ett alternativ inom produktionsplanering?
Typically, when Faurecia in Torsås are planning a new assembly line, one of the steps is to build a full-scale model of the line in card board, a form of mock-up planning. Faurecia has shown interest in finding an alternative methodology. The purpose was to explore the possibility of replacing today's cardboard based mock-up planning with models in a digital simulation environment.The purpose of the thesis has been to answer some of these complex questions; What are the benefits of using a simulation tool? In what way can we use it? If we choose to use a simulation tool, in what way does it affect our way of planning an assembly line? What are the advantages and disadvantages? Are there any economical and social aspects?Our results made us realize that a digital simulation tool does not replace the card board. On the other hand simulation could be used as a complement.
Utvärdering av laddningskoncept för lastbilsbatterier
When drivers overnight in the truck lots of electric energy is consumed by heaters, fans, lights and other extra equipment. If the engine is not running, this energy is taken from the lead/acid batteries of the truck which then needs to be recharged during operating hours. The fact that the charge acceptance of the lead/acid batteries is dependent on the temperature makes it hard to fully recharge the batteries at lower temperatures. A negative charge balance can lead to starting problems within a few days use in cold climate.In this thesis work, the effects of different battery charging concept are evaluated on the most common Scania battery (175Ah). A battery model is implemented in Matlab and some simulations of charging are made.
Eld som naturvårdare : Kärlväxtflora och vegetationsutveckling efter naturvårdsbränning i två småländska naturreservat
This study has taken place in two nature reserves in the municipality of Uppvidinge in the Kronoberg region in southern Sweden. These have been chosen by the County Administrative Board to be part of a bigger landscape of fire affected nature, and prescribed fire has been implemented in these. The areas are called Ösjöbol and Berga fly and have been burned 2012 and 2013 respectively. Non-burned areas have been inventoried as well. Vascular plants and mineral soil have been inventoried with the Hult-Sernander-Du Rietz scale of five levels. Issues emanate from the County Administrative Board?s goals for prescribed fire: how sticks and herbs were affected, how much soil was uncovered, how the structure and fire favoured species were affected, and how deciduous trees and spruces (Picea abies) were affected. The study shows that the soil increased, as well as the fire favoured species.
Coreträning: finns det ett samband mellan bålmuskulatur och balans?
Coreträning består av statiska och dynamiska övningar för bålmuskulaturen. Syftet med studien var att ta reda på om det fanns ett samband mellan bålmuskulatur och balans samt om en träningsperiod med Coreträning kunde påverka balansen. En litteraturstudie har gjorts där åtta artiklar granskades. Dessutom bestod studien av en empirisk del där nio försökspersoner fick sin statiska och dynamiska balans testad före och efter en 4-veckors period med Coreträning. Som mätmetod användes unilateral stance test med NeuroCom® Balance Master® 8.03 och dynamic balance test med Biodex® Balance System.
Modellering av supra och englaciala vattenkroppar detekterade i markradar data från Grönland
Earth science is a dynamic system science that explores the structures and processes of the earth. Knowledge about the earth is important for citizens since the science is a vital part in the sustainable development of the society. Without good basic knowledge the citizens don?t have the possibility to anticipate in the questions and decision-making that concerns e.g. anthropogenic climate change. In the Swedish school system earth science is not an independent subject until academically studies at the University?s.
Funktionsupphandling av solelanläggningar
This thesis aims to contribute to improved functional procurement of photovoltaic systems, PV systems. Functional procurement means that criteria concerning a function are set rather than specifying technical details or products. Possible advantages and difficulties in using functional procurement have been analyzed by interviews, simulations and a case study. Electricity production and surplus production for different scenarios have been simulated via MATLAB. The MATLAB script was also used to generate rules of thumb on feasible solar fraction for six different load profiles; a church, a farm, a car mechanic, an office, an industry and an apartment building.
Utvärdering av datorprogram för användning vid dagvattenutredningar
The main object of this diploma work thesis is about how computer programs can bea tool to use for work on stormwater investigations. The advantage of using acomputer program compared with calculations made by hand is evaluated anddiscussed. The computer programs that have been used for studies and a sequence oftesting of the possibilities are Autodesks Storm and Sanitary Analysis and DHIs MikeUrban.Focus on sustainable development now permeates the building industry. As a resultstormwater investigations have been conducted in an increasing extent the recentyears. Stormwater is water produced due to precipitation, such as rain and snowmelt.Stormwater investigations normally contain descriptions of existing land use, plannedland use and suggestions of measures and technical solutions for the future disposal ofstormwater.The initial part of the thesis consisted of literature studies on stormwater andstormwater investigations to understand the science.
