Utredning av frekvensregleringens påverkan på mekanisk utrustning i en kaplanturbin

As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz.However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system. Frequency controlling implies large and frequent servo forces and longer travelling distance of the sliding bearings in the Kaplan turbine.Based on one selected Kaplan turbine, Selsfors G1, measurements and MATLAB calculations have been performed in order to determine forces and movements of the linkage system. With these forces and movements as input, stresses and fatigue have been determined as well as sliding distances, bearing pressures and wear of bearings during a typical lifetime of 40 years.The results indicate that no severe wear exists on the bearings during 40 years of service.

Röst och hörselnedsättning : Akustisk analys av röst hos sju hörapparatsanvändare

A number of studies have been made to examine several aspects of voice production in individuals with different types of hearing impairments. Most of the studies were made to explore the impact that hearing aids have for people with severe or congenital hearing impairment. So far it has been confirmed that there are changes regarding voice production in these individuals. A group that has not been investigated regarding voice production to a larger extent are hearing aid users with an acquired hearing impairment. In the present study the voice production of seven individuals, four men and three women, with a moderate acquired hearing impairment is examined.

Stöd, reflektion och hjälp att inkludera : Lärares syn på specialpedagogisk handledning

The purpose of this study was to gain deeper knowledge about the special needs of guidance significance as an aid to students based on teachers' views and perceptions.Eight teachers from three different municipalities, active in primary school and middle school have been interviewed since all have participated in and have experience with special needs tutoring. Their responses were compiled and answered the three research questions: What experiences have teachers of special education counseling? How do teachers the guidance they received from a special teacher? What effect has the special educational guidance given for the inclusive education? The result shows that the special educational tutorial helps teachers gain a deeper understanding of students in need of special support and guidance to the mission vary in scope and content. The special educational tutorial that is aimed directly at the teachers seem to have a positive effect on inclusion and a critical/dilemma perspective while the consultative guidance primarily directed towards the adaptation of educational material and allows students to walk out of the classroom to receive special education promotes exclusion and ability grouping and a compensatory perspectives. From a sociocultural perspective pointing results of the study that teachers with special education tutoring experience to students in an inclusive education contribute to each other's learning,creating meaningful for everyone involved..

Inkarnationens ontologi : En studie av Wolfhart Pannenbergs kristologi i belysning av uppenbarelse som historia

Summary in EnglishThe purpose of this essay has been to examine the Christology of Wolfhart Pannenberg, and especially his interpretation of the belief in Jesus as true God and true man. The consequences for his ontology and his view of the incarnation are also focused upon.Fundamental features in the Christology of Pannenberg demand a closer examination in this connection. First, christological method regarding which a certain development can be shown from the early to the late writings of Pannenberg. According to my view, the later Pannenberg is more balanced in his way of describing the christological movements "from above" and "from below" and how these movements complement each other. In contradistinction to his mature Systematic Theology, in Jesus, God and Man from the 1960s he was more categorically an advocate of the from-below-perspective.Secondly, Pannenberg risks his entire Christology claiming the historicity of the resurrection.

The planning of this facility and especially its planned location in Sunneberg aroused a significant negative response from the citizens, demanding a better alternative for the location.The proposition resulted in heavy protests from the citizens as the planned location was viewed as an important recreation area, where the citizens could experience nature first hand, close to the centre of town. As a result, some citizens living close to the planned location, formed a network called "Bevara Sunneberg", whose purpose was to influence the decision-makers and make the citizen?s voices heard.
