Comics und der myopische Blick : Strafen fรผr unerwartete und wirkungsvolle Texte
A remarkable indictment and conviction following the sale of an โobsceneโ comic book invites us to examine arguments brought forth to describe a specifically childlike reception of new media, as usually suggested by those who would motivate legal restrictions for such media. Trying to explain some perceived contradictions on the surface of these arguments, we discuss whether it is the failure or rather the extreme success of texts that is marked as โdangerousโ in such contexts
Saving Grace on Feathered Wings: Homing Pigeons in the First World War
Soldiers of the First World War came in all shapes and sizes. The humble homing pigeon is one of the more unique and critical examples of such. They served in the armed forces of both the Allies and the Central Powers. Used as a last-ditch form of communication, the homing pigeons were exceptional in the work of sending messages back and forth between the battle lines. Little has been written about their vital role and even less in the rigorous training the birds and their handlers both endured. Understanding their training is critical to understanding how the homing pigeons performed so well under the extreme conditions of combat

BAJA SAE: Building an Engineer
of the necessary experience needed to perform the job with a high level of competence. Simulating this real-world experience in a classroom or lab becomes difficult when it has to be squeezed into a class like senior design. While for some, a good grade might be incentive enough to put forth the effort to properly gain these experiences, other things will likely become a larger priority. The SAE student design series introduces students to a competitive atmosphere that promotes extreme learning growth in a short period of time. Each portion of the competition has a specific aim that, when combined together, train a student into an engineer who is far more experienced and educated than one born from a traditional classroom. The opportunities that come from this competition, presented both to learn and grow more familiar with the real world environment of engineering are invaluable. It submerges students into an environment that encourages and promotes growth in every dimension.Cockrell School of Engineerin
Time series analysis for financial market meltdowns
There appears to be a consensus that the recent instability in global financial markets may be attributable in part to the failure of financial modeling. More specifically, current risk models have failed to properly assess the risks associated with large adverse stock price behavior. In this paper, we first discuss the limitations of classical time series models for forecasting financial market meltdowns. Then we set forth a framework capable of forecasting both extreme events and highly volatile markets. Based on the empirical evidence presented in this paper, our framework offers an improvement over prevailing models for evaluating stock market risk exposure during distressed market periods. --ARMA-GARCH model,ยป-stable distribution,tempered stable distribution,value-at-risk (VaR),average value-at-risk (AVaR)
Application of GeoSHM System in Monitoring Extreme Wind Events at the Forth Road Bridge
ยฉ 2019 by the authors. Implementation of Structural Health Monitoring systems on long-span bridges has become mandatory in many countries to ascertain the safety of these structures and the public, taking into account an increase in usage and threats due to extreme loading conditions. However, the successful delivery of such a system is facing many challenges including the failure to extract damage and reliability information from monitoring data to assist bridge operators with their maintenance planning and activities. Supported by the European Space Agency under the Integrated Applications Promotion scheme, the project 'GNSS and Earth Observation for Structural Health Monitoring of Long-span Bridges' or GeoSHM aims to address some of these shortcomings (GNSS stands for Global Navigation Satellite System). In this paper, the background of the GeoSHM project as well as the GeoSHM sensor system on the Forth Road Bridge (FRB) in Scotland will be briefly described. The bridge response and wind data collected over a two-year period from 15 October 2015 to 15 October 2017 will be analysed to demonstrate the high susceptibility of the bridge to wind loads. Close examination of the data associated with an extreme wind event in 2018-Storm Ali-will be conducted to reveal the relationship between the wind speed and some monitored parameters such as the bridge response and modal frequencies
