Showcases of Revolutionary Transformation:: Exhibitions in the Early Meiji Period
Auf den – gemeinhin als Meiji ishin bezeichneten – politischen Umbruch vom Frühjahr 1868 folgte ein Jahrzehnt revolutionären Wandels, der die japanische Gesellschaft von Grund auf umgestaltete. Ohne die Berücksichtigung kultureller Praktiken jedoch lassen sich die Stoßrichtung und Tragweite dieser „Meiji-Revolution“ nicht erfassen. Der Beitrag untersucht daher den Wandel anhand des Mediums öffentlicher Ausstellungen. Die Institution der Ausstellung offenbarte die revolutionären Ansprüche und Praktiken der neuen Eliten sowie die Reaktionen der Bevölkerung auf diese Ansprüche und Praktiken mit besonderer Deutlichkeit, denn es gab während der Meiji-Zeit keine andere Veranstaltungsform, die so viele Menschen an einem einzigen Ort hätte zusammenbringen können. Es wird gezeigt, dass Ausstellungen weniger Abbilder als vielmehr Träger des Wandels waren: Mit ihnen und durch sie ließen sich politische Ambitionen artikulieren, welche die im Entstehen begriffene Nation repräsentierten, Ordnungen des Wissens verhandelten und neuartige Konsumkulturen erprobten. Ihre Durchführung ließ dabei stets unterschiedliche, ja, entgegengesetzte Tendenzen hervortreten: Kontinuitäten und Brüche, wobei, längerfristig betrachtet, letztere dominierten
Epigenetics review and synthesis: autism spectrum disorder, postpartum depression, and posttraumatic stress disorder
The current review explores epigenetics-the way in which the environment influences genetic expression-to examine the crucial role the environment plays in mediating genetic effects on behavior. Specifically, this paper examines epigenetics with respect to three different mental health issues: autism spectrum disorder (ASD), postpartum depression (PPD), and posttraumatic stress disorder (PTSD). Much research in these areas has shown that domestic environmental influences impact the onset of these disorders. The purpose of this review is to show how genetics and the environment interact to alter genetic expression and ultimately, behavior. By doing so, this review justifies the need to study epigenetics and proposes ideas for future areas of research within the field. By understanding how the environment and genetics interact, clinicians can develop appropriate clinical interventions to aid those with ASD, PPD, and PTSD.Honors CollegeThesis (B.?
Repeatability: some aspects concerning the evaluation of the measurement uncertainty
Various publications stress the importance of the repeatability (i.e. precision) of the calculation of the measurement of uncertainty. We reveal by detailing an example from production control in the pharmaceutical industry that the effect of other influence quantities should not be neglected, because their magnitude is even larger than the contribution of repeatability. We review the role of repeatability within the calculation of measurement uncertainty for several common validation and day-to-day measurement scenarios. They show that measurement models need to consider the measurement sequences of the various scenarios. Otherwise the size and effect of the repeatability might be overestimated. At the end Monte Carlo simulations were used to investigate the determination of the repeatability under certain restrictions. The simulation uncovered a significant bias toward the common formula for calculating the standard deviation when it is based on a duplicated measurement of a sampl
Modelling three-way catalytic converter oriented to engine cold-start conditions

A definitive version was subsequently published as https://doi.org/10.1177/1468087419853145[EN] This article introduces a physical model of a three-way catalytic converter oriented to engine cold-start conditions. Computational cost is an important factor, particularly when the modelling is oriented to the development of engine control strategies. That is why a one-dimensional one-channel real-time capable model is proposed. The present model accounts for two phases, gas and solid, respectively, considering not only the heat transfer by convection between both, but also the water vapour condensation and evaporation in the catalyst brick, which plays a key role during engine cold-start. Moreover, the model addresses the conductive heat flow, heat losses to the environment and exothermic reactions in the solid phase, as well as the convective heat flow in the gas phase. Regarding the chemical model, the oxidation of hydrocarbons and carbon monoxide is considered by means of the Langmuir-Hinshelwood mechanism. Three layers make up the model structure from a kinetic point of view, bulk gas, washcoat pores and noble metal in the catalyst surface. The model takes fuel-to-air ratio, exhaust gas mass flow, temperature, pressure and gas composition as inputs, providing the thermal distribution as well as the species concentration along the converter.Real, M.; Hedinger, R.; Pla Moreno, B.; Onder, C.

A comparative-historical study of the Manenguba languages (Bantu A.15, Mbo cluster) of Cameroon.
The Manenguba languages are a group of closely related Bantu languages spoken on the north-western edge of the Bantu area. The main goals of this study are to reconstruct Proto-Manenguba (PM) from which the present day languages have developed and to examine how they are related to each other. In chapter two, the correspondences for consonants, vowels and tones are established and oroto-phonemes proposed. In chapter three, the sound changes that have apparently taken place between PM and the different languages are presented and discussed. Several diagrams are included to highlight the kinds of splits and mergers that have occurred. Chapter four is devoted to a comparison and partial reconstruction of the morphology of the noun class and concord system. In chapter five, PM roots are compared with Proto-Bantu (PB) reconstructions in order to examine the sound correspondences between the two proto-languages. Special attention is given to the apparent double reflexes of voiceless PB stops in North West Bantu languages which have recently been attributed to a former lenis/non-lenis distinction. Apparent non-procductive morphophonemic alternations In one of the languages (Akoose) are brought to light involving reflexes of the above stops, although we are not able to provide a satisfactory answer as to their origin. Chapter six is concerned with the classification of the Manenguba languages. Previous classifications and some recent lexicostatistical classifications are surveyed. We then present and discuss our own lexicostatistical sub-grouping of the Manenguba languages plus their relationship to some adjacent languages. This classification is then related to the previous classifications and to shared sound and morphological changes established in chapters three and four. The data on which the main part of this study is based is appended comprising some 700 comparative word lists from fourteen languages/dialects. Also included where possible are PB and proposed PM reconstructions of the lexical items

EduBal: An open balancing robot platform for teaching control and system theory
In this work we present EduBal, an educational open-source hardware and
software platform for a balancing robot. The robot is designed to be low-cost,
safe and easy to use by students for control education. Along with the robot we
present example tasks from system identification as well as SISO and MIMO
control. Using Simulink, students can quickly implement their control
algorithms on the robot. Individual control parameters can be tuned online
while analyzing the resulting behavior in live signal plots. At RWTH Aachen
University and ETH Zurich 28 units have so far been built and used in control
classes. In first laboratory experiences students show high intrinsic
motivation and creativity to apply the studied concepts of control theory to
the real system.Comment: Accepted for publication at the 21st IFAC World Congress 202
