Vilka faktorer inverkar vid valet av transportföretag? : En fallstudie om företagskunders resonemang och prioriteringar vid köp av transporttjänster och val av transportföretag.
During the last couple of years the focus for many businesses have moved from just being price oriented to include such factors as quality, flexibility, service, delivery precision and environmentally friendliness. The shift in viewpoint arises from the increasingly competition on the market and the hard economic atmosphere. It has become more important to differentiate the company and its products to be able to increase market share. The purpose with this master?s thesis was to get a better understanding on how companies (customer to DHL) are reasoning and prioritizing when choosing Swedish carriers.

Styrsystem : För en forskningsutrustning
The division of Engineering Materials at Linköping University, department of Management and Engineering, conducted a research project concerning Fatigue life of thermal barrier coatings during 2009. During this project equipment to provoke these fatigue failure by rapidly heating and cooling test subjects in cycles, was ordered.Design and manufacturing of the equipment was handled internally at LIU.The equipment was built using a furnace that is lowered and raised over the table where the test subject is placed. To keep the temperature of the furnace a lid slides in place to close the downward facing opening of the furnace when it is in the raised position. On this door there is nozzle that is used to cooling of the test subject by air.To make sure that the equipment can work independently you need an automation controller that can evaluate if movement can occur without danger of collisions. The control system also needs to monitor that all elements are performed according to plan.This degree project is based on a modular system from OPTO 22 and includes the configuration of a PLC that will be supplied with logic and a user interface.The degree project resulted in a graphic interface in which a user can set desired values for different parameters and get information about current values for them.

Vårdanställdas efterlevnad av informationssäkerhetspolicys : faktorer som påverkar efterlevnaden
Informationssäkerhet är ett område som kommit att sättas alltmer i fokus hos organisationer. Tidigare har främst tekniska lösningar för att skydda viktig information fått uppmärksamhet, det är först på senare tid som informationssäkerhet har börjat uppfattas som ett komplext område som innefattar såväl tekniska, som organisatoriska och mänskliga faktorer. För att eftersträva en god informationssäkerhet inom organisationen bör ett grundligt arbete läggas på att utveckla informationssäkerhetspolicys och säkerhetsansvariga måste kontinuerligt utbilda och skapa medvetenhet hos anställda kring vilka hot som finns mot organisationen ifall informationssäkerhetsbestämmelser inte efterlevs.Huvudsyftet i föreliggande studie har varit att undersöka vilka faktorer som styr anställdas efterlevnad av informationssäkerhetspolicys. Ytterligare delsyfte har varit att undersöka hur den faktiska efterlevnaden av informationssäkerhetsbestämmelser avspeglar sig inom två vårdverksamheter i Landstinget i Östergötland. För att uppfylla studiens syfte har fallstudier genomförts där såväl observationer som intervjuer med personal legat till grund för datainsamlingen.Resultatet visar att säkerhetsmedvetandet och efterlevnaden av säkerhetsbestämmelser inom de undersökta organisationerna är tämligen god, men det finns skillnader i graden av efterlevnad.

Kvalitetssäkring av stordimensionella gjutgods : Produktion och kontroll av formgjutna komponenter
AbstractA continuous improvement of products and production is an important goal for a modern industrial company. A small engineering group located in Sweden came in touch with the authors of this report during the spring semester of 2014. The aim of this report is, as part of the group´s ambition of improvement, to analyse ways in which the quality of component casted parts can be verified. Non-destructive testing (NDT), and methods to use it for quality control, is the main focus of this report. However, fields such as material standards, component casting and quality engineering are analysed as well.
Bemästra, bistå eller både och? : En kritisk studie av Provincial Reconstruction Teams roll och agerande i Afghanistan
The specific task of this thesis is to illustrate the complexity of a cooperation between civilian and military entities by examining Provincial Reconstruction Teams (PRTs) and their role as an actor among others in the field in a war-torn Afghanistan.By using counterinsurgency strategy as an analytical framework it has been possible to examine the civilian and military contexts closer. Underlying structures concerning the norms and interpretation of reality of the PRTs has been partly revealed. Studies of the PRTs as one significant bearers of "the comprehensive approach", which includes a holistic approach regarding the use of civilian and military capabilities, new conclusions can be drawn on whether a general civil-military approach can be a part of the solution for current and future conflicts. Based on the counterinsurgency strategy, the author has identified three themes as bearing and thus appears through the thesis as a foundation. These are Coordination, Development and Security.

The world around us is shrinking and globalization and capitalism are processes affecting the world. Global trends, like outsourcing and relocation of firms to low-cost countries, have become more common. This creates a huge vulnerability in the municipalities that today are concentrated around a single large company. One of these is Olofström which today is one of the most vulnerable municipalities in Sweden and whose survival today lies in the hand of the company ?Volvo Cars Corporation?.
Framgångsfaktorer för trygghetsboende. En utredning av olika aktörers inställning i trygghetsboendefrågan
Assisted living is a relatively new form of housing that received a government definition in 2007 in conjunction with a government appointed investigation of future alternative accommodation for senior citizens. The type of accommodation is intended for seniors who have the need for increased security, which may be a consequence of that they feel anxious or lonely. It concerns ordinary homes with qualities that suit needs of seniors. There is no allowance from the local municipality required in order for seniors to apply for these homes and so assisted living should not be confused with nursing homes/ sheltered housing. The purpose of this study is to identify success factors for a winning concept for assisted living in the Gothenburg region, on behalf of Skanska Project development.
