This paper describes an investigation into ATC complexity as a contributory factor in changes of safety level. ATC complexity, together with equipment interface and procedural demands comprise the task demands on the controller; subsequent controller activities are mediated by performance shaping factors to create workload. In order to establish a link between ATC complexity, a controller’s sub...

Modern commercial aircraft have extensive automation which helps the pilot by performing computations, obtaining data, and completing procedural tasks. The pilot display must contain enough information so that the pilot can correctly predict the aircraft’s behavior, while not overloading the pilot with unnecessary information. Human-automation interaction is currently evaluated through extensiv...

We describe a dialogue model and an implemented annotation scheme for a pilot corpus of annotated online chats concerning bargaining negotiations in the game The Settlers of Catan. We will use this model and data to analyze how conversations proceed in the absence of strong forms of cooperativity, where agents have diverging motives. Here we concentrate on the description of our annotation sche...

ABSTRACT A mathematical model of a synchronization block of a DS-CDMA system is developed and then investigated using a simulation. For this synchronization a pilot sequence has been used that can be a pseudorandom sequence or a chaotic sequence of a limited length. The theoretical model is tested by simulation. It was shown that the system can be synchronized using a pilot sequence represented...

Eddi et al. [Phys. Rev Lett. 102, 240401 (2009)] presented experimental results demonstrating the unpredictable tunneling of a classical wave-particle association as may arise when a droplet walking across the surface of a vibrating fluid bath approaches a submerged barrier. We here present a theoretical model that captures the influence of bottom topography on this wave-particle association an...

Physician workforce planning tools are needed to address the adequacy of the nation’s physician workforce to meet its health needs. Since health care is an inherently local phenomenon, physician supply and demand need to be understood in the local area context. Therefore, we seek to build a Local Area Physician Workforce Planning Model that emphasizes a local perspective. To that end, we are de...

This paper describes development of the conceptual and mathematical models for the part of the Waste Isolation Pilot Plant (WIPP) repository performance assessment that is concerned with what happens to the waste over long times after the repository is decommissioned. These models, collectively referred to as the "The Disposal Room Model," describe the repository closure process during which de...

Multi-species water quality models can be used to predict the fate and transport of contaminants such as arsenic in water distribution networks. In recent work, water quality models have been used to simulate hypothetical contamination events, estimate potential human health effects, and characterize the ability of sensors to detect contamination. Little work has been done to calibrate water qu...

STOCK DEFINITION AND GEOGRAPHIC RANGE There are two species of pilot whales in the western Atlantic — the Atlantic or long-finned pilot whale, Globicephala melas, and the short-finned pilot whale, G. macrorhynchus. These species are difficult to differentiate at sea; therefore, some of the descriptive material below refers to Globicephala sp., and is identified as such. The species is considere...

To reduce pilot contamination, a downlink precoding algorithm was put forward for Large-scale MIMO system. It set the Least Square (LS) criterion to the objective function, and then solved the precoding matrices with the Lagrange multiplier method. In the solving, it utilized not only the estimated channel information but also the pilot contamination information, which was acquired from some bl...
