Modell zur Vorhersage von Prozessparametern eines Laserprozesses auf Basis von RGB-Farbwerten
No full textKünstliches neuronales Netz mit zwei verdeckten Schichten mit 50 bzw. 25 Neuronen und einer ReLU-Aktivierungsfunktion. Die Ausgabeschicht hat eine sigmoide Aktivierungsfunktion. Für das Training wird ein Adam-Optimierer verwendet, der den mittleren quadratischen Fehler der Vorhersage gegenüber der erwarteten Ausgabe minimiert und so die Gewichte des Netzes bestimmt.
Eingänge zw. 0 und 1:
b: Blau im RGB-Farbraum
g: Grün im RGB-Farbraum
r: Blau im RGB-Farbraum
Ausgänge zw. 0 und 1:
hatch_um: Der Hatch-Abstand zwischen Scanlinien in µm
power_mw: Die Laserleistung in mW
pulse_us: Die Pulsrate in µs
speed_um_s: Die Scangeschwindigkeit in µm/s
Skaliert wie folgt:

Menu Costs and Inflation Asymmetries - Some Micro Data Evidence
Get PDFThe paper explains the observed asymmetric inflation response to value-added tax (VAT) changes in Hungary by calibrating a standard sectoral menu cost model on a new micro-level CPI data set. The model is able to reproduce important moments of the data, and finds that the asymmetry can be explained by the interaction of menu costs, (sectoral) trend inflation and forward looking firms, thereby it provides direct evidence to the argument of Ball and Mankiw (1994).Menu Cost, Inflation Asymmetry, Sectoral Heterogeneity, Value-Added Tax

Firm-level adjustment costs and aggregate investment dynamics – Estimation on Hungarian data
Get PDFThis paper uses Hungarian data to estimate the structural parameters of a firm-level investment model with a rich structure of adjustment costs, and analyzes whether non-convex adjustment costs have any effect on the aggregate investment dynamics. The main question addressed is whether aggregate profitability shocks (as a result of monetary policy, for example) lead to different aggregate investment dynamics under non-convex and convex adjustment costs. The main finding is that while non-convex adjustment costs make investment lumpier at the firmlevel, they lead to a more flexible adjustment pattern at the aggregate level. This is because the model is calibrated to have the same proportion of inactive (i.e. non-investing) firms under convex and non-convex adjustment costs, but the average size of new investment of active firms is higher under non-convex adjustment costs.Capital adjustment costs, lumpy investment, irreversible investment, aggregation

Why Everyone Should Join a Union
No full textThe US Congress just forced a labor agreement on rail workers, despite the fact that more than half of the rail union members didn’t want it. If they can do this, why join a union in the first place? Amazon and Starbucks workers are attempting to form Unions as well, but those companies are strongly opposed to unions, too. What are unions for, why should people join them, and given that history of the labor movement’s greatest victories–things like mandatory weekends and safety regulations–why don’t we all bend over backwards to strengthen collective bargaining? In this discussion, Why? host Jack Russell Weinstein asks his guest whether unions “corrupt” capitalism or if they are necessary components of a just society.

MAIN CHARACTER IN KUNG FU PANDA MOVIE BY EITHAN REIFF AND CYROUS VORIS
Get PDFABSTRACTThis paper is entitled "The Main Character in the Movie Kung Fu Panda byEithanReiff and CyrousVoris". The research data was taken from a film entitled Kung FuPanda. Data collection was carried out through observation methods by watching, reading andtaking notes. Then categorized based on theory. The collected and classified data were analyzedqualitatively and descriptively based on the characterization theory proposed by Kenney(1966), Three Dimensional Aspects proposed by Lajos Egri (1987). The results of the analysis,it is known that Po Ping is the main character in the film. The author uses three-dimensionalaspect of the main character's based on theory proposed by Lajos Egri (1987) which arephysiology, psychology, and sociological aspect. From a psychological point of view the maincharacter shows that he does not give up easily and tries his best to fulfill his destiny as a dragonwarrior, from a physiological point of view the main character is shown by Po as a big fatpanda. From a sociological point of view, the main character is the son of a ramen noodle sellerand become a dragon warrior.Keywords: Character, Characterization, Method of Characterization, Three Dimensions ofCharactersABSTRAKTulisan ini berjudul "Tokoh Utama dalam Film Kung Fu Panda oleh Eithan Reiff danCyrousVoris".

The Power to Resist: A Study of Dissidence Movements in Eastern Europe
Get PDFCan resistance to a totalitarian regime be possible? When a regime is so tightly controlled by a single leader or a group of people, opposition may seem impossible. Through the theories of Hannah Arendt and Vaclav Havel and the activism of Adam Michnik, I explore the question of the possibility of resistance. Given their different perceptions of totalitarianism, Arendt and Havel see extremely different possibilities of resistance. For Arendt, with a regime controlled by a single leader who has complete power over all aspects of life, opposition is extremely unlikely. However, Havel and Michnik see that resistance is possible because the regime is controlled by a single ideology which dictates the lives of even the leaders. In my paper, I explore how the two drastically different conceptions of totalitarianism account for two equally different possibilities of opposition
External Human-Machine Interfaces on Autonomous Vehicles: The effect of message perspective and memory load on pedestrian crossing intentions
No full textPerspective-taking is the ability to see a situation based on the viewpoint of others. In autonomous vehicle-pedestrian (AV-P) interaction, the perspective taken by the pedestrian could be affected by the design of an external Human-Machine Interface (eHMI). However, currently, there is little knowledge about the effect of message perspective on the crossing intentions of pedestrians when interpreting the intention of an AV. This study aims to investigate the effect of eHMI message perspective and cognitive load on participants’ perspective-taking, as inferred from their crossing intentions. We designed a photo-based experiment and examined the effect of message perspective (egocentric (from the pedestrians' point of view): ‘WALK’, ‘DON’T WALK’ vs. allocentric: ‘BRAKING’, ‘DRIVING’ vs. ambiguous ‘GO’, ‘STOP’), and cognitive load on the crossing intentions, response times and pupil diameter of the participans (N = 103). We added a memory task to increase the cognitive load during two-thirds of the trials, since crossing intentions can be demanding (the traffic scenario can be complex complex or the pedestrian is distracted) and therefore might influence perspective-taking. The results showed that the egocentric messages were most persuasive as demonstrated by more uniform crossing intentions and faster response times compared to allocentric and ambiguous messages. When participants were put under cognitive load, a more efficient strategy was used to make a crossing decision as demonstrated by faster yet consistent crossing intentions compared to no memory task. No difference in cognitive load was measured for both message perspective and cognitive load at the moment of response, as evidenced by equal pupil size. Concerning the ambiguous messages, ‘GO’ encouraged crossing and the ‘STOP’ inhibited crossing, which points towards an egocentric perspective taken by the pedestrian. We conclude that pedestrians initially take an egocentric perspective if the eHMI message is ambiguous, though this egocentric bias can be overcome by using explicitly an egocentric or allocentric eHMI message perspective. In addition, we conclude that participants perform better (more uniform crossing decisions, faster responses) when the eHMI’s message perspective is egocentric rather than allocentric.
