In order to optimize calf welfare and health it is important to know the behavior of cattle in free ranging conditions. When the cow is about to give birth to a calf she will leave the heard about 12 hours before. It is then rather obvious that isolating the cow about calving time in a single pen is imitating the cows? natural behavior. To save space and minimize building cost it?s common that the farmers build calving pens for four of five cows especially at larger farms.

In recent years, increasing emphasis has been placed on streamlining the supply chain. Keeping inventory and warehouses is considered to be a waste of resources. It is however difficult to completely eliminate the need for inventory and warehouses in a supply chain. The purpose of warehousing is to provide a service for the customer. By keeping what the customer demands in inventory it is possible to make a quick delivery when a need arises.

GE Healthcare wants to investigate whether additive manufacturing would be an alternative method in their workshops in the Umea? plant. Additive manufacturing is called 3D printing in everyday language and manufactures details by building them up layer by layer in an Automated machine. The purpose of this work is therefore to investigate how mature additive manufacturing methods are and how they could be used at GE.The work has been divided into three parts. The first section investigates how additive manufacturing would work in the production workshop at GE.

Erytrocyten, den röda blodkroppen, innehåller proteinet hemoglobin (Hb) vars främsta uppgift är att transportera syre till kroppens alla vävnader. Tillgången till tappat blod från blodgivare är mycket viktig inom sjukvården. Det är viktigt att blodpåsen tappas, hanteras och lagras på rätt sätt för att undvika onödig hemolys av erytrocyter. För att se till att hemolysgraden håller sig under det rekommenderade gränsvärdet på <0,8 % utförs regelbundna kvalitetskontroller på erytrocytkoncentrat (e-konc) vid förvaringstidens utgång som är 42 dagar. Syftet med studien var att undersöka hur hemolysgraden (%) i erytrocytkoncentrat stiger under förvaringstiden, samt att se om upprepad mekanisk hantering vid tillverkning av dessa påverkar hemolysgraden.

AbstractAttitudes towards the reference situation and the meetings between library users and librarians have become the subject of much debate in the library setting today. The aim of this two years master´s thesis has been to examine six librarian?s attitudes and apprehensions concerning the interactions between the librarian and the users in the library setting. We were also interested in knowing how a library can work to become more service oriented and customer centred. We conducted six interviews with librarians located at three different libraries in Sweden.

This study examined the factors influencing dairy farmers´ decisions to invest in Automated milking systems (AMS). The problem studied involves uncertainty, information and complexity for dairy farmers in specific decision contexts. The frame of reference in the thesis combines contingency theory and decision theory and is used in a qualitative analysis of a set interview with dairy farmers who have recently bought an AMS and salespersons from Delaval, one of the AMS suppliers.The aim of this study is to develop an understanding of the decision making processes of dairy farmers, and in particular to identify which types of factors influence the outcome of an investment decision in the technological development of a farm.The study uses Thompsons` (1967) theory about the structure that organizations develop to handle the input of information. Thus, interest is focused on how a farm business structure handles information in the AMS decision, investigating the differences in information with Delaval?s "feed first principle" system and Lely?s "free cow traffic" system.The results of the qualitative interviews with the dairy farmers who bought an AMS show that there are three important factors that influence the outcome: employees, suppliers and the owner.

Föreliggande arbete utgör en delstudie i projektet Automatiserad telefonuppföljning inom Kriminalvården. Projektets övergripande syfte var att undersöka tillämpbarheten av Interactive Voice Response (IVR) som en modern metod för utvärdering, övervakning och påverkan av intagna som blivit villkorligt frigivna från ett fängelsestraff. IVR är en metodik baserat på automatiserade telefonintervjuer som bl. a innebär att en dator har programmerats för att ringa upp, ställa frågor, registrera svar och ge feedback till klienterna. I tidigare publikation från projektet undersöktes med hjälp av automatiserade telefonuppföljningar (IVR) hur stress och mående samt användande av alkohol och droger utvecklas under de trettio första dagarna efter avslutad anstaltsvistelse (Andersson et al, 2011).

This thesis was conducted at Linköping University and SAAB Aerostructures, Linköping, and focuses on the automation of flexible fixturing in machining applications. At Linköping University a project called "Koofix" is conducted with support from Strategiska stiftelsen and several manufacturing industries including SAAB Aerostructures. The purpose of this project is to develop a more cost-effective, flexible, technique for fixation of workpieces during processing and assembly.Fixtures are an important part during the machining process, especially if you process the parts with high accuracy. Today a large number of fixtures are used at SAAB and they would prefer to reduce the number of fixtures by using flexible fixtures instead. SAAB uses one fixture for each article and this result in a high fixture cost and it also takes time to design and construct a new fixture.There are several advantages with using a flexible fixture such as that you can process workpieces with different length, height and thickness in the same fixture.

?För ett automatiserat återskapande av inbyggda systems funktionella arkitektur från källkod ochprodukt data?Den ökade komplexiteten i inbyggda system inom fordonsindustrin tillsammans med de striktaresäkerhetsrestriktionerna som infördes av ISO26262 standarden, kräver bättre kunskap ochkännedom om produktarkitekturen. Men, för befintliga produkter som inte var utvecklade enligt enväldefinierad arkitekturmodell, så måste en modell återhämtas.Syftet med detta examensarbete är att automatisera återhämtningen av funktionella arkitekturenför fordons inbyggda system, vilket är ett krav för många av ISO26262 aktiviteter. Dettaexamensarbete föreslår och beskriver två modeller för det inbyggda systemet i ett fordon, och visardess användning för att bland annat generera användarvänliga vyer. Återhämtningen av modellernasker genom att tolka den inbyggda C-koden och bearbeta fordonets data såsom inblandadestyrenheter, deras adresser och CAN buss detaljerna.Två modeller har föreslagits för att fånga den återskapade informationen om inbyggda systemet iett fordon: en produktmodell för inbyggda system och en mjukvaruarkitektur modell för deninbyggda mjukvaran.

Quickmatch is a company that recruits students to other companies that need temporary workers. Today all administration is done by hand, which is very time demanding and therefore inefficient. Employees send assignment reports by e-mail about the working hours and breaks to the administration office. Since these reports are handled manually, there is a great need for an Automated system that makes the company more scalable.The purpose of this work was to solve the defined problem, i. e.

Bakgrund: Högre grad av automation i lager har blivit en viktig och tilltagande trend. Lager är en viktig komponent i de flesta flöden och essentiellt i strävandet av önskade servicenivåer då de ofta verkar i det avslutande stadiet i flöden där ordern förbereds och levereras till kund. Den ständigt växande konkurrensen på marknaden har dock lett till att lagerverksamheter ständigt måste arbeta med kontinuerlig förbättring. Genom eliminering av icke värdeskapande moment skapas förutsättningar för att uppnå effektivare lager och överlag en högre kvalitet i lagerverksamheten. Kvaliteten som erbjuds samt kvalitetens betydelse för kunden är det som utgör den totala kvalitetsnivån, eventuella avvikelser från denna nivå betraktas som brister.Syfte: Syftet med studien är att genom kartläggning beskriva hur påfyllnads- och plockprocessen på den automatiserade delen av Staples lager utförs.

Developments in milk production are heading towards fewer but larger herds where the milking process is often fully Automated. Automatic milking systems were launched in the 1990?s and in the year 2010 the Automatic Milking Rotary (AMR) was introduced. As a rule there are no supervision personnel present during the milking event in systems with automatic milking. This means that there is a risk that cows can be incompletely milked in one or more udder quarters, for example if the robots fail in attaching the milking cups or if the cow kicks off the milking unit.
