TIME-SERIES ANALYSIS AND MODELLING TO PREDICT AVIATION SAFETY PERFORMANCE INDEX

Safety performance index is a tool with the potential to grasp the intangible domain of aviation safety, based on quantification of meaningful aviation safety system properties. The tool itself was developed in the form of Aerospace Performance Factor and is already available for the aviation industry. However, the tool turned out to be rather unsuccessful as its potential was not fully recognised by the industry. This paper introduces performed analysis on the potential and it outlines new

The impact of returning to a daytime schedule on sleep, performance and mood after simulated fixed and rotating split shift schedules

Split shift schedules which minimise consecutive hours awake and maintain adequate total sleep time per 24h may be a suita-ble alternative to long shifts. However, when returning to a daytime schedule (RTDS), performance and sleep deficits may occur as a result of changing the timing of sleep and wake periods. The first aim of the current study was to check whether fixed and rotating split shift schedules with 20h time in bed (TIB) per 48h minimised cumulative deficits in sleep, performance and

EFFECTS OF PLACEMENT ERRORS ON PERFORMANCE OF VLF METAL DETECTOR HEADS

Metal-detector performance depends heavily on the sensor head. Errors in coil placement within the head can lead to degradation in detector performance. Electromagnetic modelling of typical very-low-frequency detector heads shows the effect of coil placement errors on detector sensitivity. Provided the bucking coil ‘tracks’ the receive coil, required error corrections can remain small. A correctly-aligned head could detect a gold ring target at a range of about 12 cm.

EXPERIMENTAL VERIFICATION OF PSYCHOPHYSIOLOGICAL PERFORMANCE OF A SELECTED FLIGHT PERSONNEL AND SW: PRESURVEY FOR TRANSPORT SAFETY

Flight personnel have various factors that cause high psychological stress during the performance of flight tasks, thereby influencing their psycho-physiological experience, which may be a cause of a breach of air traffic safety. The paper presents the results of an experimental verification of task management under load, which allowed selection of probands from a sample of 100 participants in the presurvey. Overall, 70% of the probands achieved better results than the minimum level of success

To evaluate multi-target video tracking results, one needs to quantify the accuracy of the estimated target-size and the Cardinality error as the well as measure the frequency of occurrence of ID changes. By surveying existing multi-target tracking performance scores and, after discussing their limitations, the work proposes three parameter-independent measures for evaluating multi target video tracking. The measures consider target-size variations, combine accuracy and cardinality errors

This paper presents an analysis result of grasp-move-and-twist motions of robotic hands equipped with optical three-axis tactile sensor to evaluate performance of a new control algorithm based on tactile slippage sensation. The optical three-axis tactile sensor is capable of defining normal and shear forces simultaneously. The proposed algorithm consists of robot arm and hand controls based on parameters of normal and shear force, and slippage detection. To improve performance during grasp

ANALYSIS OF HEAT DEMAND AND THERMAL COMFORT IN NATURALLY VENTILATED SINGLE-FAMILY HOUSES OF VARIOUS CONSTRUCTIONS

for passive one. The building architecture included climbing plants (shedding leaves for the winter) above living room windows across the entire south side façade. Internal blinds were also used to prevent excessive solar gains. The building had a heating system and natural ventilation. 3. METHODS The analyzes were based on the results of the building performance simulation. The thermal model was prepared in the OpenStudio program [12], and the calculations were carried out in the EnergyPlus (EP
