Loose Id, scored for orchestra (piccolo, 2 flutes, 2 oboes, 2 clarinets in B-flat, B-flat contrabass clarinet, 2 bassoons, contrabassoon, 4 horns in F, 3 trumpets in B-flat, 2 trombones, 1 bass trombone, tuba, timpani, percussion (3 parts), violin I, violin II, viola, violoncello, and contrabass), is an abstract realization in sound of the energy of the Id. Unleashed, without the counterbalance of Ego or Superego, the Id generates unbridled instinctual energy, resulting in an orgiastic frenzy. Distinct from a state of dementia, this piece represents a thoroughly lucid and intentional rampage of self-indulgence. The accompanying essay examines the underlying structural principles of Loose Id, focusing on how they aid the creation of the overall experience of the piece. Particular attention is given to the concepts of linearity and nonlinearity and their roles in different levels of creative and listening processes.

The work was concerned with experimental study of the turbulent flame development process of alcohol fuels, namely ethanol and butanol, in an optically accessed spark ignition research engine. The fuels were evaluated in a single cylinder engine equipped with full-bore overhead optical access operated at typical stoichiometric part-load conditions with images captured using high-speed natural light imaging techniques (or chemiluminescence). The differences in flame development between the fuels was analysed to understand better the impact of high and low alcohol content fuels on combustion. Advanced image analysis, in conjunction with Ricardo WAVE simulation, allowed for the conclusion that the faster burning exhibited by ethanol was the result of the marginally higher laminar burning velocity providing a faster laminar burn phase and accelerating the flame into the turbulent spectrum thus reducing bulk flame distortion and better in-cylinder pressure development. Such physical reactions are often over-looked in the face of chemical differences between fuels. A further study into the variation of maximum in-cylinder pressure values was conducted focussing on iso-octane and ethanol. This study identified two phenomena, namely “saw-toothing” and “creep” in which cluster of cycles feed into one another. From this it became clear that the presence of high pressure during the exhaust process had a large influence on the following cycles. This is another often overlooked phenomenon of direct cycle-to-cycle variation whereby incylinder pressures during blowdown can dictate the duration, load or stability output of the following cycle. Finally the work investigated the impact on flame development of alcohol fuels when the overlap duration was altered. While the engine produced counterintuitive figures of residual gas, ethanol was confirmed as having greater synergy with EGR by displaying less impacted combustion durations c.f. iso-octane. Care should be taken however when analysing these results due to the unique valve configuration of the engine.

Regeringen beslutade den 21 december 2015 att införa tillfälliga ID-kontroller vid landets gränser. Detta på grund av att den dåvarande flyktingkrisen enligt regeringen innebar en allvarlig fara för allmän ordning och säkerhet. Denna uppsats analyserar den proposition, riksdagsdebatt samt följdmotioner som låg till grund för lagen genom en idealtypsanalys. En hel del kritik uppkom i samband med lagen, dels på grund av bristfällig beredning, dels på grund av dess påverkan på asylrätten. Studien undersöker hur riksdagspartierna förhåller sig till asylrätten i relation till den motsättning som kan urskiljas mellan nationell suveränitet och deklarationer om mänskliga rättigheter. Resultatet visar att de flesta riksdagspartier anser att asylrätten principiellt är viktig men att nationens intressen kommer i första hand. Centerpartiet och Vänsterpartiet värnar istället i första hand asylrätten, vilken de ser som en absolut rätt.
