The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

The purpose of this thesis was to examine if there where fallacies in the design solutions for the business system IFS Applications from a user perspective, and if so, correct these from a cognitive science approach.Data collection consisted of three main portions. These where; workshop, individual interviews and observations. The collected data was analyzed and resulted in identification of two main areas in the application that where found lacking.The result of the study showed that the usability for processing large amounts of data and the lack of customization where the main flaws in the application. Two low fidelity prototypes where created with the purpose of rectifying the underlying flawed design solutions that where identified from the collected data..

Language choice is a required course in years 6-9 of compulsory school. Those who do not wish to study a Modern language of French, Spanish or German may choose language choice English or language choice Swedish instead. These two courses are meant to provide students with additional support and advanced work in those subjects. Although grades are given in Modern Languages, language choice English and Swedish do not merit a grade. Neither language choice English nor language choice Swedish has a set curriculum or syllabus.

Influenza is a viral infection that affects global health and economy with its endemic and sometimes pandemic spread. Rapid detection of Influenza viruses enables antiviral use and can bring financial savings. It is also essential for the global surveillance of prevalent Influenza strains. RT-PCR is considered the most specific and sensitive method for detection of Influenza, but Influenza mutates at a high rate and it is therefore crucial that RT-PCR methods are updated regularly.In 2014, Cepheid released their Xpert Flu/RSV XC assay, which can detect Influenza A and B and RSV by multiplex RT-PCR in approximately one hour. The aim of this study was to evaluate this assay at Laboratoriemedicin Västernorrland by using the laboratory?s previous PCR assay for detection of Influenza viruses as reference method.Real-time RT-PCR was used to compare Xpert Flu/RSV XC to the reference method.

This report is the result of a thesis carried out during the spring of 2010 at Sandvik Coromant in Gimo. The purpose of this thesis has been to make an inventory and mapping of information used by flow groups that are most relevant for the day-to-day work. This mapping will then form the basis for information supplied by an automated system.The project consisted of:Identifying how the information is supplied today.Inquiring into the needs of an automated system.Which needs of information that will be provided by the system.Data collection occurred in two ways, both through observations and interviews. Observations of the participants were carried out early in the thesis, where the aim was to create a picture of the problem, and gradually develop a basis for the actual interview study. At each observation, an unstructured observation was used, which means that all activity was recorded.

Dagens informationssamhälle har bidragit till att människor, maskiner och företag genererar och lagrar stora mängder data. Hanteringen och bearbetningen av de stora datamängderna har fått samlingsnamnet Big Data.De stora datamängderna ökar bland annat möjligheterna att bedriva kunskapsbaserad verksamhetsutveckling. Med traditionella metoder för insamling och analys av data har kunskapsbaserad verksamhetsutveckling tillämpats genom att skicka ut resurskrävande marknadsundersökningar och kartläggningar, ofta genomförda av specialiserade undersökningsföretag. Efterhand som analyser av samhällets befintliga datamängder blir allt värdefullare,har undersökningsföretagen därmed en stor utvecklingsmöjlighet att vaska guld ifrån samhällets enorma datamängder. Studien är genomförd som en explorativ fallstudie som undersöker hur svenska undersökningsföretag arbetar med Big Data och identifierar några av de utmaningar de står inför tillämpningen av Big Data analyser i verksamheten. Resultatet visar att de deltagande undersökningsföretagen använder Big Data som verktyg för att effektivisera befintliga processer och i viss mån komplettera traditionella undersökningar.

Creating a database to manage medical data is not the easiest. We create a database to be used for a presentation tool that presents medical data about patients that is stored in the database. We examine which of the three databases, MySQL with relational design, MySQL with EAV design and MongoDB that are best suited for storing medical data. The analysis i performed in two steps. The first step handles the database that is most effective to retriev data. The second step examines how easy it is to change the structure of the various databases. The results show that depending on whether efficiency or maintenance is most important, different databases are the best choise. MySQL with relational design proves to be most effective while MongoDB is the easiest to maintain..

A growing population together with a change in food habits to a more diverse diet containing more animal products such as meat and milk makes the possibility to produce and sell products of cattle a growing market. And at the same time there is an ongoing debate about global warming, where raising cattle is questioned due to their high production of enteric methane. To be able to raise animals in a more environmental friendly way and at the same time improve productivity in a developing country such as Vietnam would be favorable. The use of feed additives with high electron affinity could decrease the methane production and at the same time improve the gross energy digested. Nitrate and Sulfur are both good electron acceptors, but due to its toxic effects the use of nitrate in feed has been neglected.

The kitchen is one of the most important rooms in our homes. It is a place for social engagements, meetings between people and activity. How the kitchen looks today is a concept sprung from the Swedish kitchen standard of 1952. Eventhou this standard no longer exists it is a model of how kitchens are designed today. The kitchens most often sold today come from one of four major kitchen manufacturers in Sweden.My thesis investiges an alternative kitchen concept.

Arbetstillfredsställelse kan definieras som ?en positiv (eller negativ) evaluerande värdering av arbetet eller arbetssituationen? (Kaufmann, G.,  & Kaufmann, A.  2005 s. 269). Denna studie fokuserar på delaktighet,  arbetsinriktning, fysiska betingelser, lön, ledarskap och sociala betingelser som delar i arbetstillfredsställelse. Syftet med studien var att undersöka hur extraarbetande högskolestudenter på lager uppfattade sin arbetstillfredsställelse, därför intervjuades nio studenter varav tre kvinnor i åldern 21-33.

The present BA thesis is an analysis and a close reading of the French author Gabrielle Wittkop's novel Le Nécrophile (1972). The analysis consists of two parts. The first part focuses on the story and can be described as an attempt to interpret the engine of the history. The second part of the analysis focuses on the narrative; how the story is told. Le Nécrophiles main motif is re-encoding the representation of death in art and literature, traditionally conceived as a beautiful female corpse.

This case study aims to explore how decision making is performed under circumstances characterised by high uncertainty. We have identified and interviewed two types of organisations dealing with investments in pharmaceutical drug development, a business characterised by high uncertainty. We have found that the two types of organisations we have interviewed display different decision making behaviour evaluating the same type of investment. Further we have explained these differences in decision making behaviour by using relevant decision making theories. This study has showed that different forms of decision making are appropriate depending on the conditions facing the decision maker..

In the year of 2009 the conditions for managing primary healthcare in the region of Västra Götalandchanged. The decision was taken by the regional assembly and resulted in that the citizens since thenhave had the opportunity to choose which health care provider they preferto stay with. Along with thisdecision a new market for private health careproviders was established, which resulted inincreasedcompetition between the providers.In order to manage the competition, the health care providers arenow forced to be more efficient in their operations andalso to beeven more focused on their patients.Backa Läkarhusgruppen is an example of a private healthcare provider in the region of Västra Götaland.In the same way it is also an example of anorganizationin need of analysing their operations to seehowit can be further optimized to meet patient needs and expectations.The aim of this study is to analyse Backa Läkarhusgruppen?s organization and its operationsin the hopeoffinding suggestions whichwill improve the patient flow.To allocate and solve the problems thatBacka Läkarhus suffer from,an approach inspired by Lean Healthcare is used throughout the report.Some of themost significant problems that were identified within the organization are:?The synchronization of demand and capacity is inadequate.?Absence of standardized routines.?Absence of present leadership.To be able to improve the patient flow Backa Läkarhus needs to handle these identified problem areas.By synchronizing the staffing level in relation to the trends in demand a reduction in the patient?swaiting times and throughput time will be possible. Creating clear responsibilities and routines for thestaff will contribute to a higher degree of patient focus and thus lead to a more efficient patient flow.

Ovarian stimulation in assisted reproduction often leads to the production of a high number of oocytes. After fertilization of these oocytes, the resulting embryos can be cryopreserved for later use. Vitrification is a recently introduced method for cryostoring embryos, showing high survival rates for both cleavage stage embryos and blastocysts. Characteristic of vitrification are high concentrations of cryoprotectants and ultra fast freezing which makes the material glassily. A major concern with vitrification has been the direct contact of the cryo-solutions with liquid nitrogen.

In this study I?ve examined bilingual high-school students? experiences of their education held in their native language. The purpose of this study is to examine bilingual high-school students? experiences of how their school organizes the education that?s held in their native language, and how the students feel that the education in their native language has helped their overall language development and also in terms of learning in general. To complete this study I?ve interviewed six high school students and analyzed their answers using other studies and theories on this subject.
