This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.

People are usually directed towards each other in conversations, to make it easier to hear what is being said. Algorithms for voice and speech recognition works in a similar way, regarding the microphone direction towards the sound source. In this thesis in electronics has therefore a servo control with binaural sound localization been implemented on a microcontroller connected to two microphones.When people perceive sound, the brain can estimate the sound source direction by comparing the time taken by the sound reaching one ear to the other [1]. The difference in time is called the interaural time difference, and can be calculated using various techniques. An exploratory comparison between the techniques cross-correlation and cross-spectrum analysis was carried out before implementation.

The energy in laundry rooms, in form heated air, can be utilized with a heat exchanger. A concept and an early prototype of the heat exchanger have already been developed to show that the theory works. This report describes the continued development and construction of the product.A field study was made in order to investigate the environmental usage and establish the product design. The most common washing machine was used as a calculation model, and calculations were also made to estimate the amount of energy in the air. A previous analysis of the existing prototype is also presented in this report, to show the products potential capacity.

Jönköping Energi AB (JEAB) is a local energy supplier for the county of Jönköping. JEAB also maintain the local Metropolitan Area Network (MAN). They have recently installed GPON in a portion of their network and have connected it to the MAN via an Extreme switch.However JEAB would prefer to use Cisco equipment instead of Extreme since the MAN comprises of Cisco hardware. They require a solution to connect GPON to the MAN with a recently purchased line card (Cisco 7600 ES20) which can be installed in a Cisco 6500 Catalyst switch. There is also a possible solution with an Alcatel-Lucent 7450 ESS-1 switch.

Lundbergs Plåt AB is a small company situated in Jönköping. Their main task is to process different kinds of steel such as stainless steel. Lately, they have shown an interest in Lean production.On the basis of the situation mentioned above, we developed the purpose to find and decrease the non value-added wastes in the production at Lundbergs Plåt AB. Out of this, we also developed and answered two questions: Which wastes can be found with help from a value stream mapping (VSM)? In what way can these wastes be reduced and how can these reductions contribute to an improved production? VSM is the method used to find the non value-added wastes.

As a result of global competition, companies within the automotive industry are required to improve their production systems to achieve sustainable and competitive production. To attain operational excellence, companies have adopted concepts like lean and World Class Manufacturing (WCM).In order to deliver, companies need to increase the availability and reliability of production equipment. This demands focus on both operational and strategic maintenance, and efficient equipment acquisition and management. The main objective of this thesis is to identify processes and success factors that are necessary for improved maintenance performance. By conducting a case study and by performing a literature review, the following has been studied: 1) how companies within the automotive industry work with maintenance and maintenance strategies, 2) implementation of maintenance strategies, and 3) new acquisition and spare parts management for maintenance. The results show that basic maintenance concepts and related terms are well defined in the literature.

In this report two Sustainability Life Cycle Assessments are carried out for two types of tiles for Riksbyggen, to contribute to a sustainable urban transition. Sustainability Life Cycle Assessment involves performing a life cycle assessment based on four principles based on scientific research and presented by the non- governmental, non-profit organization, The Natural Step. The principles concern raw materials, chemically produced substances, degeneration of nature and social conditions.Origin of products, manufacturing sites and manufacturing procedures were initially completely unknown and much of the work has consisted of finding the entire cycles, understand manufacturing processes of ceramic tiles and evaluating what materials and what type of energy sources that are required for the production. A socially sustainable perspective has been of high relevance alongside an ecologically sustainable perspective.The report begins with the basic underlying facts and the purposes of this investigation and that the reasons why Sustainability Life Cycle Assessments are carried out are to provide Riksbyggen and the own workers with documents presenting Riksbyggens ideas regarding sustainability and to hopefully get the ideas further down in the supply chain. The methods used to fulfill the investigation are presented and scientific facts about LCA and ceramic building materials are reviewed.

The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.

Title: Violin technique in folk music education. The purpose of this research has been to examine how violin teachers who are folk musicians teach violin playing techniques. Through litterature studies and qualitative interviews I have studied the relationship between teaching methods regarding violin playing techniques of the two genres folk music and classical music and how the teachers in the study relate to this. Mywork shows that the teachers use a variety of methods and material from both genres which they have come in contact with through different parts of their education.Jag har undersökt hur fyra fiollärare inom genren folkmusik arbetar med fiolteknik med sina elever. Genom litteraturstudier och kvalitativa intervjuer har jag undersökt relationen mellan undervisningstraditioner för teknikövning inom genrerna folkmusik och klassisk musik och hur lärarna förhåller sig till detta.

The aim of this study is to investigate ordinary readers' evaluation of quality in literature. The main issue is which criteria ordinary grown-up readers use when they are defining their likes and dislikes in literature. The analysis is based upon qualitative interviews with six readers, two men and four women, between 21 and 59 years of age. The study is hermeneutic. Since theoretical works concerning evaluation of literature among ordinary readers are sparse, the philosopher of arts and religion Hugo A.

How do we perceive literature? In our times computer games and Internet have made us grow more comfortable to the usage of non linear storylines. But how does this apply to printed literature?In this essay, called ?From a to b through d h and o. Non linear storytelling in our time? I have focused on nonlinear literature from different time periods and I have studied novels such as James Joyce?s Ulysses as well as works by William S.

The survey aims to shed light on traditional and contemporary bottom floor frames, their construction and different insulating materials; mineral wool, wood shavings and charcoal. The purpose is to analyze and discuss the similarities and differences as well as the pros and cons with a focus on the construction and the different insulating materials. The work has been limited to comparing two different wooden floor frames. The first one is based on a real floor frame from an older building, this example is presented as the traditional floor frame in this study and are from around 1940. The other floor frame is presented as a contemporary floor frame and is based on wood building type descriptions and literature.

Even though the American author H.P. Lovecraft (1890-1937) has been praised as one of the most influential writers of horror literature in the 20th century, his style of writing has occasionally been criticized. Lovecraft was using a writing style based on strict scientific language, where the human condition and existence are irrelevant in the narrative. This includes less focus on character development and more on the importance of atmosphere and environments. I am presenting narratological analyzes of what is often considered to be three of Lovecraft?s ?greatest works?: ?The Call of Cthulhu?, At the Mountains of Madness, and ?The Shadow over Innsmouth.? These analyzes are used to highlight Lovecraft?s science-oriented language and narratological techniques, with the focus of studying what methods Lovecraft was using to give his works and his readers a sense of dread, hopelessness, and an alien atmosphere.
