A substation must be properly protected against lightning and other external effects to the equipment in the station or staff, for that we use relay protection. They should also protect against internal errors which may occur as ground faults. There are different types of protection relays, but most common are overcurrent-, distance-, residual current- and differential protection.The purpose of this thesis was to deepen our knowledge of relay protection and to use the theoretical knowledge we got from the university studies in the work process. In the process we discovered which parameters were the most essential and calculated these for all relay protections on the substation. We also carry out a comparison between two brands of relay protection, ABB and Alstom.During our work we will test and simulate the over-current relays in a program called NEPLAN, the program will also calculate the fault currents.

Abstract The present study examined if early deaf people and people with severe hearing loss perceive visual information differently than hearing people. An experiment was conducted with eight deaf participants and eight participants with normal hearing. The participants were between the ages of 18-74 years. The participants were asked to look at fifteen different images portraying manipulated illusions, and then assess if the images were of the same size. Subsequently another image depicting a different illusion with a face hidden in it was presented to the participants.

The present study deals with task-oriented conversations between a person with hearing loss and a relative or friend. The purpose was to investigate how the participants in the task-oriented context co-construct understanding, and to focus on different kind of repair strategies that the participants may use to make the hearing loss relevant in the conversation. The method used was Conversation Analysis (CA). The material consisted of eight videotaped task-oriented conversations between a person with hearing loss and their significant other. Altogether eight persons participated in the study ? four of them had a hearing loss and the other four had normal hearing.

The thesis demonstrates protection solutions that can be suitable for a camp during internationalmissions in order to resist complex threats. The threats could consist of small arms, machineguns,RPG 7, anti armour missiles, mortar, artillery, HPM-weapons, car bombs, biological and chemicalweapons as well as sabotage and theft. It?s not the technology itself that makes the threat scenariocomplex it?s the way the opponent acts during the operations. The opponent acts usually incivilian clothes and therefore he is difficult to distinguish from other civilians.

A hearing loss may affect the identity development and participation among adolescents. To understand adolescents with hearing loss in modern society, it?s of great importance to ascertain how identity- and participation processes occur in new areas, such as the internet.Objective: The aim of this study was to investigate what research shown regarding identity development among adolescents with hearing loss and whether social processes on the internet may influence the participation of this group.Method: A literature review was conducted to obtain a cohesive framework of research about participation processes and identity development among adolescents. Included articles have been published 1995-2015.Results: The results show the importance of the individual?s identification with the surrounding.

This project started when LIC Audio AB wanted help with development of a hearing aid for public rooms. The problem is that a lot of people suffer from some sort of hearing impairment. In places with a lot of people and background noise the problem becomes bigger and the sound seems to flow together. During the project we found the solution for the problem in the shape of a headphone. The headphone receives a signal from a preinstalled hearing loop.

The study emanates from the national quality registry for persons with severe and profound hearing impairment. The aim was to examine possible differences between signing deaf and adults with acquired severe hearing loss, with reference to self-assessed problems, how the hearing loss influences daily life.In total 234 adults aged 30-90 years were included (128 women, 106 men). In the registry, there are background variables and questions that the patients have answered. The results, indicated on a visual analogue scale (VAS) from 0-100, from a question ?To which extent does your hearing loss at present influence your life?? were analysed.The study was performed by pooling the results of VAS and dividing the patients into signing deaf and those with acquired severe hearing loss, and in age groups 30-60 and 61-90 years.

Background: More than half of the elderly (65-84 years) in Sweden have problems with hearing. In some studiesit?s discussed if age related hearing loss or presbyacusis is a part of natural aging or if it depends on underlyingfactors.The purpose of this literature study was to analyse scientific papers which illustrate correlations between lessknown underlying factors and presbyacusis, defined from psychoacoustic and/or neurofysiological tests.Material and method; Literature study where scientific papers, relevant to the purpose of the study and thequestions at issue were found in the database PubMed.The result shows that cardiovascular disease, hormones, diet and drugs have an influence on presbyacusis. Thehealth condition of the individual and their lifestyle matters, likewise estrogen which according to the results of 2studies has a protective effect on hearing.Conclusion; The studies show that heart attack and high systolic blood pressure in women have a correlation topresbyacusis, but not in men, - the hormone estrogen, - some vitamins, antioxidants and diet have a protectiveeffect on hearing and studies show that smoking and alcohol have negative effects..

Abstract Title: How Shops Influence the Customer to Purchase Authors: Lisa Hegestrand, Jonna Olandersson and Anna Sjödahl Advisor: Leif Rytting Course: Marketing C, 61 ? 90 ECTS Purpose Our purpose is to analyze and clarify how a number of shops work to influence their customers? in-store buying behaviour. We would also like to analyze and reflect on how and to what extent these shops use the customer?s senses when trying to influence buying behaviour. Method We have combined a deductive and inductive approach.

The project has been performed in a close collaboration with Hörsam who works in the field of hearing technology. In a first meeting with the company, the Project group was showed a few existing storage boxes for hearing aids. The company thought they were unnecessarily large with plenty of unused space and wanted a new, smarter solution to be developed.The project began with user studies in which audiologists, maintenance technicians, future users and others were interviewed. The purpose was to obtain their views on today's storage boxes and to find out how well the users maintained their hearing aids. It proved to be a large lack of knowledge regarding the management of hearing aids within the users.

Hearing is considered to be the most important sense for the communication between people. Several studies have shown that hearing loss can lead to deterioration in quality of life, reduced social activities, feelings of alienation and hence the increasing incidence of depression symptoms.An early audiological rehabilitation is a prerequisite for proper communication among people with hearing loss. Knowledge has been shown to be of great importance and structured learning and individually targeted approach can be expected to facilitate the audiological rehabilitation.The purpose of this study was to examine the effect of an educational effort for people with hearing loss where the effort was made in the distance within the audiological rehabilitation and was followed-up by professional phone support, through a randomized controlled study.The study group consisted of 69 hearing aid users who were randomized by an independent person into two groups, an intervention group and a control group. The intervention group (n = 33) had access to the book "When the sounds are weaker - on hearing and hearing aids". The group received weekly topic-based information related to the different chapters of the book, in five rounds.

The aim of this study was to examine language abilities and their correlation to reading comprehension in 12 year old children with mild tomoderate sensorineural hearing impairment. Eight children with mild to moderate hearing impairment were tested in listening comprehension, grammatical comprehension, receptive vocabulary, phonological short termmemory, word finding, semantic relations, reading comprehension, comprehension of written words and decoding of words and non-words. The results were compared to results from a comparison group. The children with hearing impairment had significantly lower results in phonological short term memory and decoding. No significant difference was found between groups in reading comprehension.
