Effective device management is not trivial due to a variety of devices and software. To keep costs to minimum companies must effectively utilize a unified solution for device management. This research investigated Funambol’s implementation of Open Mobile Alliance Device Management (OMA DM) which is the most popular device management solution. Interviews were used to set experiments and create realistic test cases. A set of devices and a collection of Funambol software were used to create device management sessions. All of the sessions were recorded, analysed, manipulated and resent to identify efficient ways of device management. Additionally, an influence of compression and buffer-like mechanisms were checked. Methods and guidelines are provided for efficient use of OMA DM as well as a reliable analysis of OMA DM Sessions under various conditions. It was found that for most data it is best to use a built-in transport protocol compressor. Hypertext Transfer Protocol’s (HTTP) deflate with a combination of client-side buffering-like mechanism at a client side performed best at most cases. Funambol’s implementation of the Binary Extensible Markup Language (WBXML), in most cases, performed very badly, even though it was designed specifically to compress OMA DM Session messages. It was found that for an efficient use of OMA DM a proper software option set (e.g. forced use of compression) may be sufficient.

The European Parliment stipulated regulations concerning the forestry vehicles operators' health and working conditions. The allowed whole body vibrations were limited, which influenced the design of the vehicles' cabin. Surveys show a strong correlation between operator's comport and their productivity. The object of the research was Rottne AB Comfort Line Cabin, which was designed to increase the comfort for the forwarder operators. The main objective was to determine the cab's inertia properties, position of the centre of gravity and the resonance frequencies of the cab as well as a system consisting of the cab and its suspension. The methods used were an impact test with Mass-Line Analysis for the cab's properties and Operational Modal Analysis for the system. For both tests a Leuven Measurement System was used, but a part of the calculations were made in parallel by use of a MATLAB code written for this thesis. In addition a suspension test was made to estimate the centre of gravity and it was here treated as the reference value. The authors used reference values and the quality of the obtained results to compare the methods used. Further proposals for future research were made together with hints how to use vibration tests more effectively.

Die Common Object Request Broker Architecture (CORBA) der Object Management Group (OMG) bietet die Chance, nicht nur eine Plattform fuer neue verteilte Anwendungen zu sein, sondern erlaubt es auch, bestehende Anwendungen und Altsoftware hersteller- und systemuebergreifend zu integrieren. Diese Eigenschaft hebt CORBA von anderen Programmierplattformen ab und gibt CORBA das Potential, eine aussichtsreiche Basis fuer kuenftige Anwendungssysteme zu sein. Das Ziel dieser Studienarbeit besteht darin, die Umsetzbarkeit verschiedener Interaktionsarten in CORBA zu untersuchen und an Beispielen praktisch auszuprobieren. Moegliche Ablaufformen aus der Literatur, aus den Systemen DCE und MPI und anhand eigener Ueberlegungen werden im ersten Teil dieser Arbeit systematisch zusammengefasst. Danach folgt eine ausfuerliche Behandlung der Architektur von CORBA und der hier moeglichen Ablaufformen und Interaktionsszenarien. Abschliessend werden acht verschiedene Versionen eines einfachen verteilten Woerterbuches vorgestellt, um einige der in CORBA realisierten Konzepte am praktischen Beispiel zu verdeutlichen. Als CORBA-Plattform stand Orbix-MT 2.0.1 (multi-threaded) der Firma IONA Technologies Ltd. unter Solaris 2.x zur Verfuegung.

Abstract Age-related hearing impairment is the most common type of hearing impairment among adults. Adult-onset hearing impairment is one of the leading causes of disease burden worldwide and it is associated with social isolation and depression. As the proportion of older people is increasing in Western countries, the socioeconomic importance of adult hearing impairment will increase notably. The aim of the present contribution was to study the epidemiological aspects of hearing and related factors among older adults. The prevalence of hearing impairment, defined either by audiometry or by a self-report, and the differences between these two were analyzed. Tinnitus and hyperacusis were also studied. Furthermore, the prevalence of ear diseases, otological risk factors, and noise exposure and their association with hearing thresholds were analyzed. In addition, audiogram configurations and certain subject-related factors and their relation to hearing were assessed. The subjects were randomly sampled from the population register and they responded to an extensive questionnaire. Otological status was examined and pure tone audiometry was conducted. Data on 850 subjects aged 54–66 years were analyzed. Hearing impairment was found to be a highly common condition with a prevalence of 26.7% when defined by better ear and 42.2% when defined by worse ear. Men had worse hearing than women. High-frequency sloping audiogram configurations were common. Self-reported hearing difficulty and measured hearing impairment seem to be associated at high frequencies. At least one ear disease or otological risk factor for hearing impairment was found among 18.4% of the subjects and noise exposure among 46%, more often by men. Interestingly, noise exposure did not seem to associate with hearing levels among subjects screened for ear disease or otological risk factors. The results of the present study suggest that hearing impairment is a highly common condition among older adults and this should be taken into account when future hearing healthcare is planned. Furthermore, it seems that most of the subjects reporting hearing difficulty had no measured hearing impairment according to the criteria applied for eligibility for hearing aid fitting in Finland. Based on the results of the present study, the criteria for hearing impairment entitling persons for hearing aid fitting should be reconsidered. / Tiivistelmä Ikäkuulo on yleisin aikuisten kuulovian aiheuttaja, ja aikuisiän kuulovika on merkittävä terveydellinen haittatekijä. Kehittyneiden maiden ikäjakauman painottuessa vanhempiin ikäluokkiin aikuisten kuulovioista tulee merkittävä sosioekonominen rasite yhteiskunnille. Tutkimuksen tavoitteena oli selvittää aikuisten kuulovikojen epidemiologiaa ja kuulovikoihin liittyviä tekijöitä. Myös kuulovian vallitsevuus määriteltynä kuulokäyrän tai tutkittavan oman ilmoituksen perusteella selvitettiin. Samoin tutkittiin muita kuulemiseen liittyviä ongelmia, kuten tinnitusta ja ääniyliherkkyyttä. Edelleen arvioitiin erilaisten kuuloon vaikuttavien tekijöiden, kuten korvasairauksien, muiden kuulovian riskitekijöiden ja melulle altistumisen, vallitsevuutta väestössä sekä niiden assosiaatiota kuulemiseen. Näiden lisäksi tutkittiin kuulokäyrien muotoja ja niiden yhteyttä tutkittavan ilmoittamaan kuulo-ongelmaan. Tutkittavat valittiin satunnaisesti väestörekisteristä. He täyttivät laajan kyselylomakkeen, heidän korvansa tutkittiin lääkärin vastaanotolla ja lisäksi heille tehtiin kuulotutkimukset. Tutkimukseen osallistui 850 55–66-vuotiasta henkilöä. Tutkimus osoitti, että kuulovika on tässä ikäryhmässä hyvin yleinen löydös ja miehillä yleisempi kuin naisilla. Tutkittavan ilmoittama kuulovika ennusti mitattujen kuulokynnysten heikkenemistä korkeilla taajuuksilla (4–8 kHz). Samoin korkeille taajuuksille laskeva kuulokäyrän muoto oli yleisin. Erilaisia kuulovian riskitekijöitä raportoi 18.4 % tutkittavista. Tämän lisäksi 46 % kertoi merkittävästä altistumisesta melulle, miehet naisia useammin. Yllättäen melualtistumisella ei näyttänyt olevan yhteyttä kuulokynnyksiin siinä ryhmässä tutkittavia, joilla ei ollut korvaperäisiä riskitekijöitä kuulovialle. Tutkimustulokset osoittavat, että kuulovika on hyvin yleinen löydös tämän ikäisillä aikuisilla. Vanhenevat ikäluokat ovat merkittävä haaste kuulonhuollolle, ja tämä olisi otettava huomioon päätettäessä kuulonhuollon rahoituksesta. Useat niistä aikuisista, jotka kokivat kuulo-ongelmia, eivät kuulokäyrälöydöksensä mukaan täyttäneet Suomessa käytössä olevia kriteereitä kuulokojesovitukselle. Tämän tutkimuksen perusteella näyttääkin siltä, että kuntoutustarvetta arvioitaessa kuulovian kriteereitä tulisi kansallisesti tarkistaa ottamalla huomioon myös huonomman korvan kuulokynnykset sekä kuulon alenema korkeilla taajuuksilla.
