Analys av verkstadsplaneringen : på Fläkt Woods i Jönköping
This paper is finishing part of the two-year master programme in Industrial Engineering and Management.Initially there was an inquiry of studying the queue-times that Fläkt Woods uses when they break down internal working orders. These times were assumed to be too generalised and does not apply to the actual value of the queue-times which generates incorrect data and delivery delays. During the work of this paper it has been established that it is not the queue-times that is the biggest problem. The problem is the shop floor control and the lack of manufacturing the right products at the right time. Therefore an analysis of the production planning process was made to bring forward the real problems.
Resurssnåla materialflöden - En fallstudie på Volvo Powertrain
From the customer?s perspective the only reason for a firm to exist is the value it creates. However, a problem within manufacturing companies is that of the total lead time, only a small part can be considered as value adding. It has further been discovered that when working with improvements businesses often sub-optimizes single processes instead of considering what benefits the entire company. Thus, when improving processes and activities it is important to have knowledge about and understand which factors that affect how the flow can be designed.Several studies have been performed with a wide perspective on process flows in order to obtain a more resource-efficient and value added flow.
Chewing behaviour of growing cattle
Chewing behaviour includes both eating and ruminating activity. Chewing behaviour is of great importance for the feed intake as through the action of chewing (i.e. eating and ruminating) animals mechanically process the forages in small particle sizes and prepare the food for digestion. As cattle grow the chewing behaviour changes along with increasing body weight and chewing efficiency is increased. The aim of this thesis was to review the available scientific literature in order to describe chewing behaviour in growing cattle, as well as the factors that affect this behaviour.

"Än en fågel, än en blomma" : En tematisk och dialogisk studie av ungmör och skaldinnor i Anna Maria Lenngrens dikter.
Anna Maria Lenngren (1754-1817) is known as one of Stockholms Posten?s sharpest satirists. Over the years many literature researchers have based their analysis and interpretations on biographical facts. This means that we miss important parts of her authorship, as she almost exceptionally has been writing role-poems. In a role-poem, the author takes a role as a fictitious narrative subject and/or another poem character.
Om Eyvind Johnsons Stad i ljus
This is a study of Eyvind Johnson?s novel Stad i ljus from 1928, first published in French as Lettre recommandée, 1927. The purpose has been to prove that motives, themes and narrative techniques characteristic to Johnson?s later writings is present as early as in this novel from the twenties. In the novel as well as in the contemporary short stories Johnson starts to explore the symbiosis between living, traveling and writing and begins to use metafictionality as a method to approach autobiographical material.
Removal efficiency of perfluoroalkyl substances (PFASs) in drinking water : evaluation of granular activated carbon (GAC) and anion exchange (AE) using column tests, and the effect of dissolved organic carbon
Poly- and perfluoroalkyl substances (PFASs) are a group of environmental contaminants that have gained increasing attention due to their potential to bioaccumulate, environmental persistence and potential toxicity. PFASs have been found in surface water, sediment, air, soil, sludge and ice caps globally, as well as in wildlife and humans. Furthermore, PFASs have also been detected in drinking water, leading to raised concerns for human health, since drinking water is one of the most significant sources of PFASs for the general population. Conventional water treatment techniques have shown to be ineffective removing PFASs, highlighting the importance for further research to develop efficient removal techniques.
The aim of this study was to investigate the removal efficiency of PFASs in water using two treatment techniques; granular activated carbon (GAC), type Filtrasorb 400®, and anion exchange (AE), type Purolite A-600. Additionally, the effect of dissolved organic carbon (DOC) on removal efficiency was studied.
Om att lära sig prestera under press
I have researched different methods for practicing with the purpose of learning some useful ways to handle my performance anxiety issues, to better understand the phenomenon, and to be able to perform better under pressure. I chose or created nine methods and used each during a decided period of time, each period ending with a performance. Afterwards I analyzed the methods with the help of audio recordings and written concert evaluations to see if it was possible to alter my practicing techniques to be more directly focused on preparing for the concert situation..
Fallstudie av produktionschefers ledarskap
The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the manufacturing line.Weight sensing systems is today a reality in trucks with air springs.
Drama & vägledning : Metoder som speglar livet
This study illustrates how drama methods and career counselling might interact. The aim is to investigate whether drama methods can enhance career counselling methods. Drama is here defined as an umbrella term that includes all forms of action methods used in psychology and education.A literature survey was carried out in parallel with qualitative research interviews. Three professional drama leaders were interviewed separately. This was followed by a group interview with five upper secondary school students, who had all taken a course in drama with a focus on personal development.The findings show that there are common and consistent goals and values between drama and career counselling.

En studie om möjligheter att stoppa förfalskningar : Spårbarheten i en global värld
The purpose of this study is to describe the traceability of products that protect against counterfeiting and examine how protection against counterfeit products have been developed to date, and to display the opportunity to streamline the protection of products and brands.Nowadays, in the global world, it is getting increasingly more difficult to track the products. Especially for the last link in the chain, which in most cases is the customer and who is constantly exposed to risks. This report deals with the possibilities of preventing and detecting counterfeit products. Fake products are not unusual in an historical perspective. It has been common with counterfeits ever since the Middle Ages continuously until today. Forgers have become more skillful and they are successful in most industries. Many of the fake products are of poor quality and can be downright dangerous to the customer.To answer the question, the author used a qualitative collection method.

Framtagning av en utvecklingsprocess för automation - baserat på konceptet Lean Automation
Due to the globalization today the competition in the market has in- creased and it requires flexibility and produce according to customer demand. In order to reduce the cost of wages industrial companies are now considering moving the manufacturing to low-cost countries. To keep up with the competition in the market without moving the manu- facturing abroad, Lean Automation was developed. The concept of Lean Automation is to reduce the perceived complexity with automa- tion and make automation available for new users and in new applica- tions.Haldex Brake Products are situated in Sweden and want to maintain the manufacturing of the automatic brake adjusters in the country. It is a product well-known and highly exposed to the competition in the mar- ket.
