Effektiv Planering enligt Lean Production : En fallstudie på Sandvik Mining and Construction
Due to a constantly increasing competitive pressure it is of great importance to constantly strive for improvements in order to gain competitive advantages. Lean Production is a concept that has been introduced with the aim to minimize waste and increase profitability. The purpose of this report is therefore to investigate how to perform effective planning according to the principles of Lean Production, in companys with customer exclusive products, through a case study at Sandvik Mining and Construction (SMC), and to investigate how SMC kan improve their planning of drifting rods at the production unit in Sandviken.The study started by creating a theoretical framework, to describe the subject planning and planning based on Lean Production. This frame work constituted the base for the case study which took place at Sandvik Mining and Construction, and also for the model and planning tool that has been introduced.The result of the study is partly a general model with factors that contribute to a more effective planning. These factors has beed identifed as SMED, which focuses on reducing set up times and in the end to facilitate the planning.
Demokrati ur politikers och ungdomars perspektiv : - En diskursanalytisk studie om demokratiska förutsättningar i Norrköpings kommun
The democratic conditions in national states have change radically at the same time as the society has changed. Because of social and economic globalization processes, the states and government has lost power for the benefit of transnational and global institutions. That affects the democracy since the nation state earlier defined the domain of citizenship. At the same time, citizens? confidence towards political parties and politicians has gone down.
Förnuft och känsla : En studie av kokböckers visuella kommunikation under det tidiga 90-talet och sena 00-talet
The interest for food and cooking has probably never engaged the people of Sweden as much as it does today. Especially cookbooks are selling better than ever which has been a quite constant trend since the mid 90's. This study explores the connection between visual communication in Swedish cookbooks and the post-modern values which have influenced the market climate and the visual culture. I have used a theoretical framework as reference consisting of theories of semiotics, visual rhetoric, marketing communications and postmodernism. I have been studying six cookbooks, three from the late 00's and three from the early 90's, from the two separate angles of their graphic design and photographic material.
Diskonteringsräntan påverkar graden av miljöpolitiska styrmedel : En studie om koldioxidskattens påverkan på koldioxidutsläppen
This qualitative study involves the implementation of Lean and Kaizen methods in a Swedish service industry. Lean philosophy is based on a method to achieve more with less. In practical terms this means that the use of an organization's resources is improved. The origin of Lean is the Toyota Production System. Now, Kaizen methods give managers and employees a better more efficient system to reach their goals within the organization or company.
Epoxidised linseed oil as hydrophobic substance for wood protection : technology of treatment and properties of modified wood
Public concern about the release of toxic compounds from wood-based products drives legislation towards enforcing industries to find and use more sustainable solutions for wood treatment. Plant oils are good alternatives to treat wood, minimizing or even neutralizing the impact on the environment. Wood modification with epoxidised linseed oil (ELO) and acetic acid as catalyst has proven a suitable method to impregnate and protect wood. However, the mixture presents a serious inconvenience because of the quick polymerization of the ingredients that limits its practical application. Therefore, this study was designed to evaluate an alternative method using a two-step process which bypassed the problem above.

One of ABB Power Systems´s business areas is HVDC (High Voltage Direct Current) technology. HVDC is used for transmissions for both short and long distances. One of Power Systems?s products is called HVDC Light. HVDC Light is a relatively new technology for power transmission, but have before only been used for motor drives applications.
Effektutveckling i den koncentriska fasen i bänkpress och knäböj
Aim: The aim of the study was to investigate 1RM and what power could be generated in bench-press and half squat concentric at certain percentages of 1RM. Special interest was put to evaluate men (M) and women (K), strength trained (ST) verses non strength trained (EST) in generating absolute power as well as power relative to 1RM.Method: In total 59 subjects mean (± SD) age 24.9 ± 4.1 years divided into four test groups: 20 male non strength trained GIH-students (EST M), 20 female non strength trained GIH-students (EST K), 10 male strength trained - sprinters on national/regional level (ST M), 10 female strength trained - sprinters (ST K) on national/regional level. They did two tests on 1RM and power in events of concentric bench-press and half squat in a Smith machine. In the first test session 3 ? 5 lifts were made to measure 1RM in each event.
Kulturarv, efterfrågan och musikalisk mångfald En fallstudie kring bibliotekariers och användares uppfattningar om musikbibliotekets uppdrag och roll
The main purpose with this Master's thesis has been to through a case study investigate and analyze the music library activity at the Public Library in Lund, in order to find out according to which ideas and principals this activity is run by. It also discusses how you at the music department handle your task as intermediary of music and how well this coincides with the users expectations. To give the research more depth a special analysis has been made, assuming the perspective of the B&I-researcher Sanna Taljas' three perspectives regarding the music department. She identifies three perspectives in maintaining a music library, which she calls the general education, alternative and demand repertoire.The examination is based on an empirical research, where five librarians were interviewed and fifty users have responded to a survey, but the essay also includes a literary study carried out to explore which ideas there are regarding the music department's missions and roles in the existing literature.Librarians and the user's opinions coincide quite well. What distinguish the most are the opinions surrounding the competency of the music library.
Kraftanalys och framtagning av mätanordning för vertikala vindkraftverket Lucias bärarmar
The project contains a force analysis of the vertical axis wind turbine Lucia's supporting arms and a measuring device to experimentally measure the forces is made. The forces between the supporting arms and the tower are calculated theoretically and then simulated by a computere. A measuring devise is then designed to measure the forces experimentally. The forces acting on the attachment between the supporting arms and the tower is primarily the centripetal force, gravitational force and the aerodynamic forces on the rotor wings. The maximum forces were theoretically calculated and is 13.38 kN along the x-axis, -0.25 kN along the y-axis and then 0.5 kN along the z-axis.
I spränningsfältet mellan kommunala gränsformuleringar och en skalpolitisk idealisering av den regionala samhällsnivån.
The parrot is a common symbol, or even cliché, in Western literature, going all the way back fromancient Greece to the present date, and in many a genre. This study reads the oeuvre of the NobelPrize winner Samuel Beckett (1906-1989) as being closely related to these certain traditions andconnotations of for example religion, satire, and speaking nonsense, in his frequent use of parrotsand their symbolic potentials, in his writing. Furthermore, it is possible to distinguish a movementin Beckett?s use of parrots, from a more or less traditionally use, to one more philosophicallyprofound.Although the parrot graces us with its presence (or at least may be traced) in almost everywork written by Beckett, from the poem ?Whoroscope? (1930) to How It Is (1961), they are onlymentioned sparsely by his interpreters. Therefore, a brief history of the literary tradition of theparrot will be expounded.
Bekämpning av fruktträdsspinnkvalster (Panonychus ulmi) med oljeemulsioner i äppelodling
Sedan införandet av bredverkande insekticider har frukträdsspinnkvalster, Panonychus ulmi
orsakat skada på äppelodlingar i stora delar av den tempererade världen. Kemiska acaricider
utvecklades först som en lösning, men deras höga toxicitet och kvalstrens förmåga att bilda
resistens har gjort dem omoderna. En lösning på problemet är sprutning med oljeemulsioner,
som främst har en fysikalisk verkan. Oljorna tillverkas av antingen mineraloljor eller
vegetabilisk oljor och används traditionellt till bekämpning av övervintrande ägg på våren.
För att bekämpningen ska vara effektiv krävs dock att den utförs när äggen är som känsligast.
Äggen hos P. ulmi blir känsligare ju närmare kläckning de befinner sig.

The method used was a literature study. Pubmed and Cinahl were used for the search of literature. Some articles were searched from scientific studies reference lists and also advice from the supervisor.The result from the different studies shows that the effect of rehabilitation varies as there are many aspects that have an affect on the outcome measure.
The Value of Relationships in a Chinese-Western Business-to-Business Context: An Investigation on Relationship Bonds, Adaptation, Trust and Commitment
The purpose of this study is to improve the understanding of the dynamics behind Chinese-Western buyer-supplier relationships. The study takes on a partially inductive approach by commencing with exploratory in-depth interviews. The main body of the study consists of a cross-sectional survey. Data has been collected through an on-line questionnaire. The theoretical review consists of industrial relationships with specific accounts on the role of adaptation, trust and commitment; a stream of literature in cross-cultural relationships deriving from Hofstede?s culturalist legacy with specific reference to Chinese-Western relationships, including studies on relationship bonding, and the role of guanxi.
Detektering av in- och utandning vil bilkörning med hjälp av Matlab
Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measuring inhalation and exhalation is questioned.The purpose of this study was to improve the efficiency of the analysis of the RIP signal. The goal was to create a new data processing tool in Matlab that automatically detects inhalation and exhalation from a RIP signal with higher validity compared to the previous data processing tool.In this study, nine tests were performed on drivers while they were driving in different scenarios such as highway, country road and in city traffic. Inhalation and exhalation was measured using a RIP, a pneumotachograph with a tightly sealed facemask and a thermocouple placed between the nose and mouth, which was used as reference to the RIP.The result of this study was a data processing tool that automatically detects inhalation and exhalation with higher validity compared to the previous data processing tool.
SAB-SYSTEMETS AVDELNING Y : Dåtid, nutid, framtid
This Master's thesis concerns the classification of compact discs according to the Swedish classification system, SAB. The purpose of this thesis is to critically study and discuss category Y of the SAB-system and its application in Swedish public libraries. The classification system has undergone great changes from the first edition in 1921 until today. In 1921 there were no musical recordings in Swedish libraries, today they are responsible for a large part of the loans. We discuss how the system's category Y has corresponded with the musical development.
