This master thesis was conducted during the spring of 2014 at Atlas Copco Rock Drills AB in Örebro. The purpose of the thesis was to develop a simulation model of the rotation system for a hydraulic rock drill. In the future, the model will be used to investigate the phenomena called ?jerky rotation?. In order to validate the simulation model a test bench was designed and tests were made.

This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

The aim of this master thesis is to study the students usage and experiences of the reference services at the university library at Linköping University. The four questions that I seek answers to are: - What kind of help do the students most often ask for at the reference desk? - To what extent do the students use the reference services for their studies? - What are the students experiences of the help they receive at the reference desk? - What are the students experiences of the treatment they receive from the librarians at the reference desk? I have studied literature that describes reference work and evaluation of reference work. I have also studied Christian Grönroos theory of service quality. I have distributed questionnaires to students at Linköping University.

Bakgrund och problem: ?What gets measured gets done? är ett välkänt ordspråk inom prestations-mätningsområdet. Den primära rollen i prestationsmätning är att säkerställa att företagets mål upp-nås och för det används mål och mått som hjälper medarbetarna att prestera väl. Detta gäller såväl i företagets supply chain som i övriga delar av verksamheten. Eftersom en supply chain i många fall är mycket komplex ökar betydelsen av styrning och mätningar.Syfte: Syftet med denna studie är att i detaljhandelsbranschen identifiera ett fåtal Key Performance Indicators (KPI) för en supply chain (SC) som kan bidra till ökad lönsamhet via materialanskaffning, lager och butikspåfyllnad.Avgränsningar: Studien avgränsas till ett företag för att kunna gå på djupet och se hur fallstudiens företag ställer sig till studiens generellt uttryckta syfte.Metod: En kvalitativ fallstudie har genomförts.

 Saab Microwave Systems (SMW) is a business unit within Saab AB that manufactures and develops different types of radar- and sensor systems for naval, airborne and ground based forces as well as within the market for civil security. In addition to the manufacturing of radar and sensor systems they also provide different types of service concepts. The business unit has 50 years of experience within the area of developing radar systems and is considered to be one of the market leaders. When applying an assemble-to-order production strategy with products at this level of cost price the product lead-time is vital and becomes an important part of the strategy within marketing and sales. Within SMW there is a new department called Supply Management (SM) that provides the supply of incoming and outgoing material. Within SM there are four sub-departments working with activities such as planning, purchasing, receiving inspection, storage and distribution.

 Date: 2008-10-06Level: Bachelor thesis within Information Technology and business economics, 15p, EIK021Authors: Anna Karlsson, akn05009@student.mdh.seLena-Maria Lindström, llm05002@student.mdh.seMagnus Wretlund, mvd05001@student.seTutor: Marie Mörndal Title: Managing IT-incidents, a case study at ICAs IT department                            OperationsKeywords: IT-incident management, IT-incident management process, IT-incident, ITIL, CCTA Problem: An organization can benefit by having an established management process of handling IT-incidents. But how can this be achieved? Are there step-by-step procedures? What´s included in the management process of IT-incidents? Is the size of the organization relevant to which model is to be chosen? Can the work of the writers of this essay result in a recommendation of a specific model for IT-incident management? These questions lead to the following essay question; How are IT-incidents managed?Purpose: The purpose of this thesis is to describe and discuss how IT incidents can be managed.Method: The writers of this essay have performed a case study at ICA, a Swedish food retail company. Eleven interviews with nine different persons have been carried out. The interviews are analyzed in the chapter called Resultat och analys.Conclusion: Our conclusion is that there are both similarities and differences in Dept.

Background: The strategic importance of purchasing departments is increasing, yet supply risks are rather uncharted. The procurement of coffee involves supply risks and the purchaser needs to be able to handle these to enable the roasting-house to produce coffee as specified. Purpose: To chart risks in connection with the procurement of coffee as well as the possibilities of handling these. The thesis also examines if general risk management theories are applicable on the supply risk present within Swedish roasting-houses and can become an integral partof the purchasing process. Method: A qualitative case study of the purchasing process of Swedish roasting- houses.

Corporate Social Responsibility (CSR) refers to adjusting corporate goals so that they are not only based on maximizing corporate profits, but include ethical standards on socially desirable behavior (Boatright, 2008). Even though many companies have integrated CSR into their business operations, there are still many issues that are difficult to tackle. Especially Multinational Corporations (MNCs) in the global business environment face many challenging situations due to the fact that they often have linkages to countries where the local government is either unwilling or unable to take care of its responsibilities. MNCs often find themselves with increased responsibilities when they start solving some of the issues that earlier have been the sole responsibility of states. A specific case situation discussed in this paper is related to ?conflict minerals?.

The cost for forestry logistics in Sweden is about 25 percent of the total cost of getting the raw material to industry (Anon., 2010). There might be much to gain by taking a look at your supply chains on the logistic side in your company. In this report the logistic chains by Mellanskog for ENA Energi AB in Enköping has been looked in to. ENA Energis plant is a combined power and heating plant and about 99, 5 percent of their fuel consisted of bio energy in year 2009 (ENA Energi, 2011, länk A). The main purpose with this report is to look at three questions: 1. How does the supply chain look today? From forest to industry. 2.
