The overall objective of this research project is the development and evaluation of a flexible and cooperative management system within SME based production networks for the ramp-up process. Inter-organizational processes of six previous ramp ups were analyzed and documented in flow charts. Highlevel executives and domain-experts of the production nets developed in moderated focus-groups standa...

Wind energy is playing an important part for ecologically friendly power supply. Important aspects for the integration of wind power into the grid are sudden and large changes known as wind power ramp events. In this work, we treat the wind power ramp event detection problem as classification problem, which we solve with support vector machines. Wind power features from neighbored turbines are ...

Another goal of the program is to assess the effectiveness of “ramp-up,” a common mitigation protocol in which source levels are gradually increased prior to the onset of full-level transmissions. Ramp-up is thought to give nearby animals some time to move away before sonar transmissions reach maximum levels. However, it is unknown whether or not this protocol is actually effective. We have dev...

Ramp schemes are means by which a (large) secret can be shared among a group of participants in such a way that only sets of at least k participants can reconstruct the secret and the amount of information that of less than k participants can obtain is strictly controlled. This is of the concept of a threshold scheme. The current theory concerning ramp schemes will be here alongside some new re...

Pipeline networks are one of the key infrastructures of our modern life. Proactive monitoring and frequent inspection of pipeline networks are very important for sustaining their safe and efficient functionalities. Existing monitoring and maintenance approaches are costly and inefficient because pipelines can be installed in large scale and in an inaccessible and hazardous environment. To overc...

Expressions characterizing the output voltage and propagation delay of a CMOS inverter driving a resistive-capacitive interconnect are presented in this paper. The MOS transistors are characterized by the th power law model. In order to emphasize the nonlinear behavior of a CMOS inverter, the interconnect is modeled as a lumped load. The propagation delay of a CMOS inverter is characterized for...

A new ramp metering strategy implemented on the Twin Cities freeway system to reduce ramp waiting times was evaluated through microsimulation of freeway activity. The study compared Stratified Ramp Metering strategy with the previous Zone Metering Strategy and with no control strategy. Comparison with Zone, which was designed to favor freeway flow, showed the new strategy succeeded in greatly r...
