The earmould acoustics affect the amplification that the hearing aid is programmed to give to its user. It is therefore important that the choices made for the earmould are correctly done. One choice is regarding the shape of the soundbore that affects the frequency response of the hearing aid above a certain cut-off frequency. The purpose of this project was to measure the frequency response when altering the shape of the soundbore in the earmould. Additionally, the aim was to examine how the frequency response is affected when the shape of the soundbore is not set or is not possible to set in the software when programming the hearing aid.

Abstract During object-oriented system development, programming should be preceded by analysis and design to assure that the system fulfils the demands of the customer and simplify during the development phase and documentation. When modeling the analysis and design phases, several different notations may be used. One of these is the UML (Unified Modeling Language) which this thesis will cover. The aim is to compare the use of the UML i practice versus what is said in the literature. The investigation is built upon interviews at different companies to receive their reflections about the UML.

Among the included parts in the boiler are cyclone, convection part andINTREX-chambers.

This paper presents a project and literature overview about how risk management and quality sometimes goes hand in hand and sometimes in two different directions. Meaning that the risk management can affect product or process quality differently depending on what risks an organisation chooses to control.The purpose with this paper is to get a deeper understanding about how risk and quality works together with IT-support and therefore we have been actively participating in a project with a risk management company called Zert. A literature study and a qualitative interview study have also been undertaken to see what the customers and the other researchers have written, to be able to make proper conclusions on the subject.To easily work together and get the information that was needed, four methods where used. Besides the qualitative interview and literature study the think-out-loud, card sorting and a variation on the extreme programming method where used to help visualize and improve communication both with Zert, the costumers and among ourselves.Zert is a risk management company that helps other organisations to control their different types of risks that they might be taking, by offering a system where the risk management process is held and providing consulting services by helping within the processes. Both Zert and their customers see the communication, knowledge and teamwork as something important as well as the quality within the work, processes and the end result.

Background: The relation between work motivation and well-being are relatively well theoretically entrenched, but few studies have been conducted on nurses within psychiatry. Objective: The aim of the present study was to examine the differences in intrinsic work motivation (autonomy, competence, relatedness), mental health and burnout between young (?40 years) and older (>40 years) nurses employed in psychiatry. Method: The study was an observational study with a cross-sectional design and group comparisons, conducted as a survey. The sample constituted of 60 employed nurses.

The objective of this study was to study the agreement between two methods of indirect bloodpressure measurement in dogs and cats and to establish the within-method variation for the methods. The utility and practicality in the clinical setting were also evaluated for the both methods. The techniques evaluated were the oscillometric method and the Doppler ultrasonographic method. Thirtytwo dogs and 26 cats were used in the study and seven dogs and five cats out of these animals had diseases that may effect the bloodpressure. Bloodpressure was measured in both anesthetized and in conscious animals.

This report describes the development and implementation of a system for transmitting digital information at high speeds from a miniaturized submersible developed by the Ångström Space Technology Centre at Uppsala University. For instance, the vehicle shall transmit image data ? even stream live video - through an optical fibre to a monitor in a ground station. Hence, the system shall be used both to convert the image data to make it transmittable, and to recreate it at the receiver.The work includes a pre-study of the programming language and the technology used. A concept for the solution is presented together with main components later broken down into internal functions.

The government appointed in 2004 a special investigator with the objective to investigate the possibility of introducing a new law concerning implementation of obligatory cash registers with certain certification. This resulted in SOU 2005:35 ?Krav på kassaregister - Effektivare utredning av skattebrott? (Proposition 2006/07: 105). Following advice received from the respondents, the government has drafted a bill submitted to parliament in March 2007. Government bill 2006/07: 105 proposals for new law on cash registers, and submitted to parliament 2007th Act (2007:592) on the cash register was adopted by parliament in March that year and came into force on 1 January 2010.

The purpose of this study was to investigate different relations between the damages of falls and background variables as well as the relation between the falls and the weather condition to later be able to use this report to expand the knowledge among workers at VTI about the pedestrian fall injuries. All of the fall injuries in the data that this study is based on have occurred in Sweden during the time period between January 2003 and December 2011.To be able to answer the questions that this report is based on several statistical methods are used. The statistical methods that have been used during the making of this report are multiple linear regression, binary logistic regression, correlation analysis, association analysis and descriptive statistics as well as visual analysis.The results of the study show that women around menopause age have a tendency to get a big increase in the amount of injuries compared to men of the same age. The study also suggests that men on average tend to have a lower level of injury compared to women.Age also seems to affect both the amount of injuries and the level of injury negatively. The study suggests that the most likely reason for this is both that the intake of ?Fall Risk Increasing Medicine?, which is medicine that increases the drowsiness, is higher among older individuals as well as lower estrogen levels among older women and lower amount of testosterone among older men, which causes a loss of bone density in both sexes.The weather seems to have a strong effect on how many injuries occur but also a noticeable effect on the scale of the injury.

This master thesis work was done by two students at Machine Design at KTH for Lesjöfors Stockholmsfjäder AB. The task was to develop a calculation program for gas springs. The program is going to ease the selection of gas springs for a given case of a lid that should be opened. The program is going to be used internal by sales people at Lesjöfors AB in Sweden and internationally. The program is therefore written in English.The program was developed in Microsoft Visual C# 2008 Express Edition.

AbstractAs a developer of database-driven applications you will be faced with difficult choices, when it comes to choosing database, server and programming language. For the result to be satisfactory it requires the different techniques to interact well with each other and also fulfill performance expectations. This is even more important when the application is deployed to the cloud and the response time plays a major role.This paper evaluates different databases and their performance. To test the databases there was an application made in the server script language PHP or Hypertext Preprocessor and it was deployed to Windows Azure cloud platform. The test applications task is to call and load databases by controlled requests which creates, reads, updates and deletes data in an relatively large extent.The results shows that locale databases or databases in the same data center as the server generates the fastest response.

Leisure boats of today have a lot of electronics that needs battery power to work. In additionto that electric propulsion systems have gotten more popular lately, which further increasesthe demand for high battery capacity. The batteries used are mostly lead-acid batteries and toget the most out of the batteries it is important to treat them right. To optimize the electricsystem it is important to have knowledge of how the batteries and the electric motor are usedand which factors affect e.g. efficiency and recharging.A new electric drive that can replace old diesel engines is being developed and needs testingand evaluation.

In 2022, Russia completed its full-scale invasion of Ukraine. The EU responded with powerful restrictive measures against Russia to demonstrate its unified support for Ukraine, indicating that the perception of Russia as an external threat to the EU, particularly in Central and Eastern Europe (CEE), has become increasingly evident following the invasion. Drawing on theory and previous research suggesting that external threats strengthen group identities, I argue that Russia is perceived as an external threat to EU identity in CEE after Russia's invasion of Ukraine. Stephan and Stephan's integrated threat theory considers an external threat as either realistic, posing a threat to the ingroup's existence, or symbolic, posing a threat to the ingroup's worldview. The purpose of this study is to examine the relationship between EU identity and the perception of Russia as a group threat to the EU among individuals in CEE based on the nature of the group threat: realistic and symbolic.
