Automatiserad Konstruktion av Varmkanalsystem

The thesis has been carried out in cooperation with Master Flow AB, Västervik owned by the EWEBE Group. The company produces and sells hot runner systems that are tailor made for the customers.The problem that MasterFlow AB has encountered is in the construction of complex hot runner systems in SolidWorks. With several different lengths, fronts and endcaps that builds the nozzles of the hot runner systems, is affecting the problems for MasterFlow AB. The purpose of this work is to automate the design of hot runner systems so it does not overload the CAD-system SolidWorks.To gain an understanding of the problem, there have been several studies and observations at the company, where the focus has been on how the work is done with the design of hot runner systems. By using help from the corporate management, enough information has been collected to find a solution to these problems.The implementation of design automation has been based on a flowchart that was created.

Bristande mjölknedsläppning hos förstakalvare : en enkätstudie

Milk ejection in dairy cows can be inhibited if oxytocin is not released from the pituitary gland. The problem with inhibition of the milk let down is not new, but has recently regained interest. It is observed during different types of emotional stress, for example when cows are moved to an unfamiliar environment, during oestrus, changing from suckling to machine milking or when being milked for the first time. The aim of the study was to examine the extent of cows with disturbed milk ejection in Sweden. A survey was sent out to 1000 dairy farmers in order to collect data about herd size, housing systems and routines at calving and milking.

Osäkerhet vid fotogrammetrisk kartering med UAS och naturliga stödpunkter

En karta är en färskvara som är i ständigt behov av ajourhållning. Ajourhållning görs normalt med traditionella metoder: fotogrammetriska och/eller geodetiska. Men i och med att utvecklingen går framåt har intresset för en ny metod, UAS (Unmanned Aerial Systems), ökat. UAS är en relativt ny fotogrammetrisk metod där obemannade flygfarkoster används. Detta examensarbete har utvärderat vilken osäkerhet vanligt förekommande detaljer i en karta kan få i framställda "produkter" som genererats med hjälp av UAS-bilder som georefererats med naturliga stödpunkter.

Säkra kommunikationskanaler i en distribuerad heterogen miljö

The systems environments of today are often distributed and heterogeneous. These kind of systems have several advantages but also disadvantages. One problem is how to keep them secure.The security problems in these environments are mainly due to the communication between the connected computers. It is relatively easy to tap these communication channels from information. There is also a need for the possibility to secure these channels from modification of sent information and to be able to verify the sender and receiver of information in a secure manner.

Unga grisars sociala beteende : hur uppfattar de varandra

Studies on wild boars have shown that piglets at 10 to 12 days of age can be introduced to pigs outside the litter without fighting. In today's production systems, the litters are kept in separate pens until weaning. At that point, the litter is divided and the piglets are placed together with piglets from other litters. This usually leads to aggressions among the piglets and may cause stress. This literature review aims to find out how piglets perceive other pigs in their surroundings.

Inhysningssystem för växande ungtjurar

The purpose of this study was, if possible, to find a housing system for growing bulls that was as optimal as possible for the animal welfare. In order to select housing systems you must take into account the size of the group, body weight and the type of floor. Seven of the international most common housing systems were compared, straw bedding, deep straw bedding, sliding straw bedding, concrete slatted floor, rubber coated slatted floor, cubicles and feeding cubicles. Studies that have examined the proportion of tail, claw and leg injuries and the presence of unnatural behavior in the different systems. In summary, all studies showed that soft underlay were beneficial for the animals in terms of the proportion of bone lesions and swellings.

Förfoganderättsinskränkningar vid fastighetsöverlåtelse : med fokus på överlåtelseförbud i onerösa avtal

The purpose of this thesis is to investigate if a transfer restriction in a conveyance of real property for consideration is legally binding. In doctrine the legal situation is described as unclear. It will also be investigated if the restriction is binding in relation to the acquirer´s creditors and in relation to a new owner of the property.A transfer restriction in a conveyance of real property for consideration is legally binding between the parties and in relation to a new owner of the property. Even though the restriction is binding between the parties and in relation to a new owner, it is not binding in relation to the acquirer´s creditors. The Supreme Court has stated that it is a general legal principle that a transfer restriction in a conveyance for consideration is not binding in relation to the acquirer´s creditors.In this thesis it will also be argued that the legal situation is inconsequent.

Föreligger det en bostadsbubbla i Stockholms Län?

In a historical view, house prices have developed at the same rate as inflation. In the end of the 20th century the prices on the housing market started to differ from the inflation rate, and today the deviation is strong and the real price increase has been very strong.The financial crisis in 2008, which was a result of a subprime mortgage crisis on the American real estate market, has made several agents on the housing market in Sweden question today?s prices. Robert Schiller, an American economist who predicted the mortgage crisis in 2008, claimed during the Nobel Prize ceremony 2013, that Sweden shows signs of a financial bubble ? "I think that people here in Sweden have an illusion that increasing prices is a lasting trend, but that is more suggestive of a bubble".

Persona : En metod att utveckla och införa persona i en organisation

AbstractIn this thesis we aim to extend the current theories about a concept called persona. A persona is a model of a user, mostly based on qualitative research and made with such accuracy that it to some extent can be used as a replacement of a real user in a development process and as a communicative tool. We will present a way of constructing this persona without meeting the actual users and follow up with interviews from the organization using them. This will lead to a model over the process of introducing personas as a concept in an organization,previously not familiar with the concept. The model is adapted to also work for projects and organizations where the concept is already known..

Förändringar av marknadsdesign och deras påverkan på balanshållningen i det svenska kraftsystemet : En kartläggning och analys av de balansansvarigas arbetsgång

A future expansion of wind power in the Nordic power system makes the balancing for the transmission system operator Svenska Kraftnät (SvK) more complicated. Up to the hour of delivery the balance responsible parties? (BRP) makes prognoses and plans, for consumption and production, to help maintain the balance in the electrical grid. How well this is accomplished is affected by the setup of the market design. Therefore SvK has proposed the following possible changes in market design: Increase the imbalance costsIntensify the regulation of imbalancesIncrease the temporal resolution on the different marketsPresent the prices for balancing power in real-timeModify the balancing market to simplify auction of consumption bidsA mapping over the BRPs? processes within planning and trading on the day-ahead, intra-day, and the balancing market has been performed in this thesis.
