Abstract
This paper presents the characterization of fundamental analog and digital circuits with a-IGZO TFTs from measurements performed at normal ambient. The fundamental blocks considered in this work include digital logic gates, a low power single stage high-gain amplifier with capcacitive bootstrapping and a level shifter/buffer. These circuits are important functional blocks in analog/Mixed signal IC design with oxide TFTs. Being fabricated at low temperature (<200 degrees C), they can find potential applications in low-cost large-area flexible systems.

Abstract
Several countries have a significant installed capacity of large-scale reversible hydro power plants. This large-scale storage technology comes with high investments costs, hence the constant search for methods to increase and diversify the sources of revenue. Traditional fixed speed pump storage units typically operate in the day-ahead market to perform price arbitrage and, in specific cases, provide downward replacement reserve (RR). Variable speed pump storage can not only participate in RR but also contribute to frequency restoration reserve (FRR), given their ability to control its operating point in pumping mode. This work proposes a strategy to manage the water resource and maximize the power plant revenue by participating in the day ahead market but also providing ancillary services. Moreover, a model to correctly allocate the water resource throughout the year is presented, as well as an evaluation module to calculate the real revenue of the system.

Abstract
In this paper it is presented a usability evaluation of an entertainment platform, well-known, YouTube. The main aim is to study how people with intellectual disabilities interact with the layout and uses their search field option. We intended to observe and analyze performance and satisfaction but also if the interface can give them autonomy on the search option. The results show that participants had a good experience with the interface, however cannot be autonomy with the search option.

Abstract
The present study investigated how vivid, i.e. sensorially rich platforms influence the urge to buy impulsively in e-commerce environments. A stimulus - organism - response model was assessed in an experiment involving two groups, one experiencing a vivid platform and the other a more informational one. The response was posited to be mediated by the affect elicited during the experience. The results show that the urge to buy was not prevalent, but it was significantly higher in the group exposed to the vivid site. The variance of urge to buy was largely accounted buy the variance of positive arousal (delight). Negative affect, as well as low arousal positive affect (relax) have small negative effects on the urge. These results confirm our expectation that a simple distinction between negative and positive affect is insufficient to predict the urge, since the level of arousal also plays a fundamental role to trigger the urge.
