Yes / The power output characteristics of the hydro turbine is one of the core contents for transient calculation of the hydro turbine generating sets (HTGS). In particular, the hydro turbine operates far beyond the given parameters region during the load rejection transient. As such, obtaining the complete characteristics of the hydro turbine becomes one of the key issues in calculating the transient process. In this study, methods for calculating the energy losses are proposed by analyzing the general characteristics of the inner energy losses within the hydro turbine. Characteristic parameters in the hydro turbine power model are calculated from the synthetical characteristics of the model hydro turbine. The transient power model of the hydro turbine has been established and applied to calculate and reconstruct the complete characteristics of the hydro turbine. Furthermore, the relationship curve between the mechanical friction loss power and the rotation speed under different head can be established by combing the runaway curve with the proposed turbine power model. This relationship is applied to construct the complete characteristics of the mechanical friction loss. Combining the proposed two complete characteristics, the power model of the hydro turbine is suitable for simulation with a wide range of fluctuations as well as the load rejection transient. Details of the computational procedures are presented and demonstrated using a case study. / The research reported here is financially supported by the National Natural Science Foundation of China under Grant No. 51579124, 51469011,51279071.

Abstract: Interpersonal skills such as perception are an important topic within sustainability discourse. Additionally, businesses play a key role in the sustainable transition the world is currently undergoing. Through this study, we aimed to investigate how business leaders and decision makers perceive the sustainability performance of the firms they work for and explore how these perceptions align with real-world circumstances. In doing so, we will discover how such interpersonal skills are being utilised within a business context. 'The study was developed using theories such as inner development skills, the Dunning-Kruger effect and Brandlogic’s sustainability IQ Matrix. We followed an inductive interpretivistmethodology to gather qualitative data through a series of interviews. The findings show thatperceptions and their accuracy are quite varied, though participants who reported higher levels of communication from their firm often had more positive perceptions. Furthermore, despite the Dunning-Kruger effect suggesting that education would have an impact on accuracy, we did not find this to be the case, rather participants who demonstrated usage of a variety of inner development skills tended to be more accurate. These findings suggest businesses who wish to improve the perception of their firm should focus on how they communicate their efforts, and those seeking to improve accuracy should focus on development of inner development skills.

Complex samples containing nanoscale or larger materials exhibit light scattering, a universal property of matter. However, the influence of scattering-induced cascading optical processes on quantifying sample scattering intensity and depolarization has not been thoroughly evaluated. This study uses polystyrene nanoparticles (PSNPs) as a model analyte for systematic experimental and computational investigation. It aims to elucidate the effects of cascading optical processes on scattering cross-section, molar coefficients, depolarization, and intensities. A theoretical model is introduced to show how the Beer-Lambert law is complicated by forward-scattered light interference in UV-Vis measurements. The dependence of scattering intensity on concentration and particle size is complex due to light scattering depolarization and inner filter effects (IFEs). Scattering depolarization increases with PSNP scattering extinction but levels off before unity, influenced by light polarization. Insights from this work enhance understanding of material characterization and nanoparticle quantification and clarify light scattering effects on absorption and fluorescence measurements.

In this thesis we shall examine the role of measurerability in the theory of Lebesgue Integration. This shall be done in the context of the real line where we define the notion of an integral of a bounded real-valued function over a set of bounded outer measure without a prior assumption of measurability concerning the function and the domain of integration. / Mathematical Sciences / M.

In the last decades a number of studies have shed light on early modern scientific experience. While some of these studies have focused on how new facts were forced out of nature in so-called experimental situations, others have charted long-term transformations. In this dissertation I explore a rather different facet of scientific experience by focusing on the case of the Prussian university town Halle in the period from the late seventeenth till the mid-eighteenth century. At this site philosophers, theologians and physicians were preoccupied with categories such as inner senses, inner experience, living experience, psychological experiments and psychometrics. In the study I argue that these hitherto almost completely overlooked categories take us away from observations of external things to the internal organisation of experience and to entirely internal objects of experience. Rather than seeing this internal side of scientific experience as mere theory and epistemology, I argue that it was an integral and central part of what has been referred to as the cultura animi tradition, that is, the philosophical and medical tradition of approaching the soul as something in need of cultivation, education, disciplination and cure. The study contains four empirical chapters. In the first chapter I analyse the meaning and function of experience in Christian Wolff’s philosophy understood as spiritual exercise and cultura animi. In the second chapter I examine experience in the theologian Hermann Francke’s cultura animi, focusing particularly on the relation between scientific experience and what scholars have referred to as religious experience. In the third chapter I chart aesthetic experience in Alexander Baumgarten’s aesthetics. In the fourth chapter I examine the role of experience in the medicine of Georg Ernst Stahl, Friedrich Hoffmann and their followers. The analysis of medical experience channels the discussion into questions regarding the relation between the cultura animi tradition and the kind of attitudes, practices and processes that have been connected to modern objectivity.

The inner city has seen significant social and economic changes in the post-war period. The purpose of this thesis is to explore the evolution of public policy and its impacts on the changing Canadian inner city, between 1960 and 1990, by using a case study, that of Southwest Montreal. Southwest Montreal was Canada's first and longtime most important industrial area, and has suffered substantial decline since the 1950s. In order to set the context for the case study, it is necessary to outline the variety of the Canadian inner city, the socio-economic changes facing it, as well as the policy responses to these changes. The case study will trace the evolution of transportation, housing and economic/industrial policies between 1960 and 1990, and ascertain the impacts of these policies according to the theories of inner-city change (policy as factors of decline, stability, and revitalization). The policy input of the three levels of government (local, provincial and federal) will be covered. The case study will also be compared to other Canadian inner cities. It was found that public policy is an important, though not decisive, factor in inner-city change, and that policy has evolved significantly in the last thirty years.

Vegetable oil methyl esters obtained by transesterification of vegetable oils are considered to be suitable alternative fuels for diesel engines. However, higher viscosity, surface tension and boiling temperatures of biodiesels may adversely affect spray characteristics as compared to those of diesel. Thus, spray characteristics of Jatropha Methyl Ester (JME) are studied by comparing them to those of diesel in a high-pressure chamber with optical access to simulate the actual in-cylinder conditions. Also, the effect of inner-nozzle cavitation on JME and diesel sprays is studied by utilizing two nozzles, one with sharp entry-radius and the other with larger entry-radius. Finally, spray characteristics of surrogate fuels such as n-dodecane and n-hexadecane are also studied. The first part of the work concerning precise measurements of inner-nozzle geometry revealed that one of the nozzles has a hole diameter of 190-µm and entry-radius of around 70-µm, while the other has a hole diameter of 208-µm and entry-radius of around 10-µm. Injection rate-shape and coefficient of discharge for JME and diesel flow through the two nozzles were then measured. It was observed that while the coefficients of discharge (Cd) are almost identical for JME and diesel, the nozzle with entry radius of 10-µm exhibited around 20% lower Cd than that of the entry-radius of 70-µm. This observation coupled with insight from complementary CFD simulations of inner-nozzle flow showed that the lower Cd of the nozzle with entry-radius of 10-µm could be attributed to inner-nozzle cavitation. The second part of the work involved measurement of non-evaporating spray characteristics including spray-tip penetration, spray-cone angle and droplet size measurement under realistic operating conditions using techniques such as Shadowgraphy and Particle/Droplet Imaging Analysis (PDIA). The non-evaporating spray of the fuels are studied by injecting them using a common-rail fuel injection system into the high-pressure chamber maintained at room temperature. Experimental results show that JME is associated with a slightly faster spray-tip penetration and narrow spray-cone angle indicating inferior spray atomization which is confirmed by around 5% larger droplet sizes. Slower spray-tip penetration, wider spray-cone angle and around 5% smaller droplet sizes are observed for the spray from the cavitating nozzle. Thus, the inner nozzle cavitation is observed to improve the atomization of diesel and JME sprays. The differences in spray characteristics of JME and diesel reduce as the injection pressure increases. The spray-tip penetrations of both surrogates are observed to almost match that of diesel. The third part of the work involved measurements of evaporating spray liquid length, vapour penetration and spread angle for JME, diesel and surrogates at conditions of 50 bar chamber pressure and 900 K temperature. It is observed that the JME exhibits around 16% longer liquid length than that of diesel. The liquid length of n-dodecane is significantly lower than that of diesel and liquid length of n-hexadecane is around 20% higher than that of n-dodecane mimicking the trend of JME and diesel. The liquid length of n-hexadecane is very close to that of diesel at all the three test conditions. Interestingly, the vapour penetration and spread angle for all the fuels is observed to be almost identical. As the cold spray and evaporating spray characteristics of n-hexadecane match well with those of diesel, n-hexadecane can be chosen as a pure component surrogate for diesel. Finally, an analytical model for predicting the spray vapour penetration is assessed with the experimentally-observed trends of penetration and spray spread angle. The model indicated that the effect of fuel density variation is compensated by the corresponding variation in injection velocity for a given injection pressure to result in a similar vapour penetration. Overall, the present work, in addition to studying the effect of fuel physical properties and cavitation on sprays, has generated a comprehensive experimental database on non-evaporating and evaporating sprays of biodiesel, diesel, and pure component surrogates, which would aid significantly in validation of CFD simulations.

Syftet med denna studie är att få en större inblick i, och förståelse av, min egen instuderings- och interpretationsprocess, samt att utveckla densamma för att bli friare i mitt musikaliska uttryck. Jag hämtar inspiration från litteratur som beskriver Konstantin Stanislavskijs metoder samt annan litteratur som bland annat behandlar ämnena instudering, interpretation, inlevelse och kroppens kommunikation. Därefter utforskar jag de metoderna och verktygen i mitt eget arbete med repertoar. Processen dokumenteras genom loggbok samt videodokumentation av mina övningstillfällen. Resultatet visar att en detaljerad inre scenografi ökar min förmåga att vara närvarande i musiken och därmed sjunga mer uttrycksfullt. Jag upplever även att sångtekniken kommer mer naturligt och det blir lättare att sjunga. / The purpose of this independent project is to get a greater insight in, and understanding of, my own process of learning and interpret songs, as well as develop it towards greater freedom in my musical expression. I examine literature on subjects such as Konstantin Stanislavskij’s methods as well as literature regarding learning process, interpretation, ability to imagine and physical communication. After reading, I explore the methods and tools when working with my own repertoire. The process is documented through a diary and video recordings from practicing. The results show that a detailed inner scenography increases my ability to stay present in the music and sing with more expression. I also experience that the singing technique comes to me more naturally and it becomes easier to sing.
