Congestion Pricing, Slot Sales and Slot Trading in Aviation

This paper studies the regulation of an airline duopoly on a congested airport. Regulation should then address two market failures: uninternalized congestion, and overpricing due to market power. We find that first-best charges are differentiated over airlines if asymmetric, and completely drive out the least efficient airline from the market. This is not generally the case for an undifferentia...

Congestion Pricing for Aircraft Pushback Slot Allocation

In order to optimize aircraft pushback management during rush hour, aircraft pushback slot allocation based on congestion pricing is explored while considering monetary compensation based on the quality of the surface operations. First, the concept of the "external cost of surface congestion" is proposed, and a quantitative study on the external cost is performed. Then, an aircraft pushback slo...

Slot Grammars

This paper presents a formalism for natural language grammars , with accompanying parser. The grammars are called slot grammars because they are organized around slots (grammatical relations) and rules for filling them. The parser works bo t tom-up and maintains, for each phrase being built up, a list called the available slots list, ASLOTS. A phrase can grow by having one of the slots in its A...

Slot Allocation Algorithms 1 Running head: SLOT ALLOCATION ALGORITHMS SLOT ALLOCATION ALGORITHMS FOR MINIMIZING DELAY IN ALARM-DRIVEN WSNS APPLICATIONS

Energy-efficiency and latency requirements in alarm-driven Wireless Sensor Networks often demand the use of TDMA protocols with special features such as cascading of timeslots, in a way that the sensor-to-sink delay bound can stay below the duration of a single frame. However, this single TDMA frame should be as small as possible. The results presented in this paper, point to the conclusion tha...
