"Eyes Without Light" is conceived and scored for symphonic orchestra. The title of this work reflects personal concerns regarding global environmental issues. The phrase "eyes without light", derived from the Gaelic term "sul gan solas", refers in this instance to the blind greed of multi-national industrial and political corporations which are responsible for the destruction of the earth's ecosystem (primarily the forests and oceans). This work, influenced by the 19th-century symphonic poem initiated by Beethoven, Berlioz and Liszt, is programmatic in nature. The busy, confrontational destructiveness of mankind is represented by repeated or moving sixteenth notes at the beginning and end of the piece. These sections utilize varying densities of semitone clusters and are predominantly dissonant. The calmness and balance of the planet earth is represented by the middle section of the work, which consists primarily of slow-moving sustained lines. These sustained lines move to a sonority which is the structural focal point of the work (m 129-131). This sonority is resolved in the final measures. Both the focal point sonority and its resolution are constructed of P5 and P4 intervals. The aggressive destructiveness of mankind is emphasized by the repeated dissonant chords in the concluding measures (m 140-147, m 151-157) of the section. / Arts, Faculty of / Music, School of / Graduate

This dissertation discusses Stirling’s cycle and its contribution using different approaches. There are calculation of Schmidt’s theory and distinctiveness between ideal and real cycle described. Based on my previous research, this work provides a detailed summary of different methods which are used to stimulate Stirling’s cycles as well as the motor as a whole. Attention is particularly dedicated to current utilization of this machine which is not broadly known within general public.

This thesis describes the design chain to indicate the measuring cylinder Stirling engine. It describes the practical problems of measurement methodology and highlights the possible pitfalls of the measuring chain. For measuring the use of pre-existing model of gamma Stirling engine modification. It was carried out systematic measurement and evaluation of measured data. As a mathematical model for comparison with the measured data was used ideal cycle and Schmidt theory.

This paper deals with the thermodynamic cycle of Striling engine. Analysis of the ideal cycle, Schmidt analysis and second-order method with loss correction by PROSA 2.4 software is applied. The results are compared with experimental data of two model engines.

Rezension des von Carmen Ottner herausgegebenen Werkes Franz Schmidt und Preßburg

Rezension des Konferenzberichts zum 13. Franz-Schmidt-Symposium

Bränder i skog och mark förväntas bli ett allt vanligare inslag i ett framtida klimat. Skogsbränder kan orsaka stora geomorfologiska förändringar i landskapet, bland annat genom vittring av block och berghällar. Antalet tidigare studier som berör vittring till följd av skogsbränder är begränsade till antal och många av de studier som finns är utförda i klimat och miljöer som skiljer sig från det vi har i Sverige. Det finns därför en relevans i att studera hur, och till vilken grad, skogsbränder påverkar vittringen av granitoida bergarter i Sverige. Med anledning av detta har en fallstudie av brandens påverkan på vittring utförts i Norra Lunsens Naturreservat. Syftet med studien var att undersöka hur vittringsgraden inom brandområdet i Norra Lunsen påverkats av skogsbranden 2017. Studien har till stor del bestått av fältstudier där såväl kvantitativa mätningar som observationer använts för att samla in data. Resultatet visar att det finns en mätbar skillnad på vittringsgraden inom brandområdet jämfört med övriga delar av Norra Lunsen. Det visar även att de olika geomorfologiska förutsättningarna inom brandområdet haft en inverkan på vittringsgraden.
