Pilot noncompliance with checklists has been associated with aviation accidents. This noncompliance can be influenced by complex interactions among the checklist, pilot behavior, aircraft automation, device interfaces, and policy, all within the dynamic flight environment. We present a method that uses model checking to evaluate checklist-guided pilot behavior while considering these interactio...

A computational model of attention and situation awareness (SA) was developed and used to predict pilot errors in the task of taxiing from runway to terminal. The model incorporates a lowlevel perception/attention module and a higher-level belief-updating module. Attentional scanning is controlled by bottom-up and top-down processes, with the effectiveness of top-down guidance varying as a func...

We present a computational model of closed-loop, pilot-displays-aircraft system designed to evaluate the impact of the addition of a synthetic vision system (SVS) to a commercial airliner cockpit. The NASA-run empirical study revealed that while pilots rarely looked out the window during most phases of approach and landing, they devoted a substantial proportion of their gaze toward the SVS. A m...

 Central composite orthogonal design was applied to quantify relations  of xylanase production, loss of dry matter and change of pH with four critical variables during solid state fermentation of a mixture of wheat bran and wheat straw on which Aspergillus niger CCUG 33991 was cultivated. The studied variables included the percentage of wheat straw, temperature, moisture content, and fermentati...

It is a well known fact that, dual fuel engines at part loads, inevitably suffer lower thermal efficiency, higher carbon monoxide and unburned fuel emission. The work in this paper is to investigate combustion characteristics of a dual fuel (diesel-gas) engine at part loads, using a single zone combustion model with detailed chemical kinetics for combustion of natural gas fuel. The authors deve...
