Alfa Laval?s strategy is to focus on modularized product platforms. Several benefits areforeseen, reduced lead-time, less costs, shorter Time To Market and better quality.Development and verifying will be carried out on block level. Today the separators arebeing tested as a complete unit. A number of factors affect the test results and problemsthat are encountered can be hard to identify.

In order to decrease the disturbance from a cable testing equipment, the company Ericsson Network Technologies in Falun determined to design a new series resonant test system with a lower frequency. The new equipment is of series resonant type with a system frequency of 500 Hz. This equipment consists of an inductor, a capacitor and a voltage source. The voltage source is the same as the old one, the cable acts as the capacitor but the inductor has to be designed especially for the new equipment. In this thesis work several air coil inductor types were examined.

Quality is the main focus in management of all laboratories. Accurate results of the analyses are not only determined by the analytical procedure but also by preanalytical factors. In the total analytical process of clinical specimens, there are many possible preanalytical sources of error. Monetoring of temperature on test samples of the transport boxes is one way to reduce the mistakes in the preanalytical phase.In this study, four laboratories from primary health care were invited to participate. The temperature has been measured on test samples of the transport boxes being delivered to the laboratory.In three cases the temperature remained within the limits, but in the fourth case the temperature varied more than the allowed interval.

Sweden?s District councils and Country councils are in itself to a large extent responsible for the state financed welfare. Because of this, Sweden has a contribution- and adjustment system. The reason for this system is to create equal chance, for all District councils and Country councils, to be able to give the citizens service independently of their income and non-influential structural differences. The adjustment is built upon the so-called standard cost method, which contains four different parts.

In order to reduce the price for, and improve the performance of automatic control systems for magnetization of synchronus generators, the possibilities of using a PC based software PLC system, Programmable Logic Controller, has been investigated. The result is a system based on the CoDeSys software PLC with runtime environment from 3S-Software, communicating with external units via Modbus fieldbus. System price is reduced from ?5000 to ?2000 and system processing speed is reduced from 10 ms for a Siemens S7 PLC to 4 ms with the CoDeSys PLC system though unsolved problems with runtime seizure caused by improper settings in the PC BIOS..

In industry applications, such as power supply plants, the issue of interaction between fluid and structure is always presented. More precisely, the fluid flow affects the structure by applying force(s) on it and vice versa. As a result, the structure can move (vibrate) or deform. A good understanding of this problem can help to design the system in term of safety, stability and efficiency.This project aims to optimize and test the Unicorn FSI solver from the FEniCS project [1] to simulate the interaction of fluid and structure in an experiment, which was carried out at Vattenfall Research and Development. The target is to improve the Unicorn FSI solver to cope with a real industrial problem.

The purpose of this study was to collect Swedish normative datafor Lundamaterialet for children aged 3:0-4:5 years. Another aim was toexamine the effectiveness of the test; if it elicits adequate responses fordeciding if a child has acquired a specific language structure or not.Normative data was collected for 195 children with typical languagedevelopment. Participants were recruited from pre-schools in themunicipalities of Göteborg, Mölndal, Härryda and Skövde. This studypresents normative data for 79 children constituting the three youngest halfyeargroups. Results show that the children had acquired more than half ofthe investigated phonological and grammatical structures and that the olderchildren had acquired more structures than the younger ones.

The aim of this study is to find out whether there is any difference to be found in the attention ability before and after physical activity. The method used in this study was made of an experimental design. The participants were chosen through a cluster sampling and thereafter divided into a control group and an experimental group. A total of 64 pupils from upper secondary school participated in the study, 25 of them in the experimental group and 39 of them in the control group. Since the measure was repeated, both in respect of time and the comparison between the groups, a mixed design was used.

In this thesis a transport system is sought after thatif realised in the city of Uppsala could provide bothwell-being to all its inhabitants and sustainability,here jointly refered to as liveability. It is found thatthe car dominated transport system that is inoperation today provides two fundamental values,namely accessibility in both time and space, whichsets it apart from other transport solutions. Thesetwo values are of immense importance for theliveability in our modern world. On the other handthe car dominated system decreases the liveabilityof Uppsala in several different ways. Some of theseproblems, it is argued, could be solved within thecar system, through the adoption of moreenvironmentally friendly cars etc., but otherproblems are inherent in the car system and willremain no matter what changes are made.

This thesis is a part of the DySCAS (Dynamically Self-Configuring Automotive System)project which has the overall purpose of creating a middleware for the electronics in an automotive environment. The thesis has been made with collaboration with ENEA AB who is a member of the DySCAS project. ENEA AB has developed a demonstration platform to test the fundamental ideas which the DySCAS project is built on.The purpose of this thesis was to design and implement a GPS application to be added to the demonstration platform. This was done by adding a GPS receiver to the original DySCAS demonstration platform and designing and implementing an application to be able to extract the information from it. The resulting application is able to present cur- rent position and absolute time to the DySCAS networks as services to be used by other applications or by the network it self.

Because of increasing demand of power on Malmbanan the capacity of the existing wires which supply the trains must be increased. This increases the stress on the existing poles and for this reason the system for supplying the loads along the railway is to be removed from the poles and be replaced by some other system. This thesis is a study on a two-level low voltage (1 kV and 0.4 kV) electrical system with the aim to investigate if it can be an alternative to the system used today taking into account the voltages, fault currents and costs.In this thesis the following tasks have been performed:? Gathering of data? Description of basic theory? Loadow and fault current calculations of the system with MATLAB? Life Cycle Cost estimate of the system? Analysis and conclusions from the resultsThe results show that the new system can be an alternative to replace today's system. The simulations and calculations show that the voltage drop is at an acceptable level and that the fault currents are large enough to supply a safe disconnection if a fault occurs at the far end of the system..

Chlamydophila psittaci is a common cause of diseases in parrots ranging from being less serious to more serious. It is also a zoonotic disease which poses serious health problems to humans. The disease is highly under diagnosed. The symptoms in birds are nonspecific and may be indicative of many different diseases which make it harder to diagnose and treat. The purpose of this study was to investigate the prevalence of C.

AimThe purpose of this study is to compare the level of activity between playing wii Sports Tennis and wii Sports boxing, and the usual sports, and to see how the two variants are perceived.Issues:- How much strain ratio and energy consumption it gives to exercise wii sports compared with the playing of sport for real?- How do the test participants experience the different tests?- How are the two wii sports games against each other in terms of activity and fitness in the school environment?MethodThis is an experimental study in which 10 test participants (5 men and 5 women) have carried out four different physical tests. The tests consisted of either playing an exergame or playing a sport for 25 minutes. Physical activity was measured during the test using a heart rate monitor. All test participants completed all tests in the same order.

Fagan Test of Infant Intelligence (Ftii) är ett parjämförelsetest som mäter spädbarns intresse för ett nytt visuellt stimuli när detta presenteras tillsammans med ett stimuli redan känt för spädbarnet, kallat nyhetspreferens. Även om Ftii har visat sig fungera väl vid bedömning av spädbarns kognitiva nivå kan testet förbättras på ett antal punkter. För att uppnå reliabla resultat har försökspersonerna ofta testats vid ett flertal tillfällen. För att undersöka möjligheterna att ytterligare validera erhållna resultat från Ftii har en version av Ftii skapats för att utföras med en ögonrörelsemätare. Denna version, kallad Ftii-Ö, har testats med hjälp av en spädbarnsgrupp och en vuxengrupp för att på så sätt utvärdera för och nackdelar med ett test utfört på ögonrörelsemätare.

This study is focusing on students at compulsory level and their performance in national exam tests when the students first language is taken into account. Students in Swedish schools with non-Swedish speaking parents commonly follow language classes for limited Swedish proficient students. How does this affect their results when tested in other subjects as physics,biology and chemistry? A general claim is that national tests can provide data for balancedand fair grades. This view is challenged in this paper, through Principal Component Analysisof test results that shows a difference between schools when the schools social position and share of limited Swedish proficient students are measured.
