Abstract

It was around the years 2003 to 2005 that a dramatic change seized the semiconductor industry and the manufactures of processors. The increasing of computing performance in processors, based on simply screwing up the clock frequency, could not longer be holded. All the years before the clock frequency could be steadily increased by improvements achieved both on technology and on architectural side. Scaling of the technology processes, leading to smaller channel lengths and shorter switching times in the devices, and measures like instruction-level-parallelism and out-of-order processing, leading to high fill rates in the processor pipelines, were the guarantors to meet Moore’s law.

Abstract

Some years ago, progress in road telematics had made it possible to introduce time travel information in real time on VMS devices. Such information can lead road users to avoid congested areas as well as to waiting in a better condition for the end of the congestion. In a way, they increase congestion, in another way, they reduce it. Our research aimed at explaining the reasons why some people behave in a way and another one in. We assumed that travel time messages may be interpreted from several points of view, depending on driver knowledges in memory, experience and will, and as a result, the decision taken. An enquiry on a group of drivers aimed at analysing mental activity involved in decision taking process will be presented.

Abstract

This field research studies human-human interactions (HHI), seen from cockpit's perspective in context of collaborative decision making (CDM) during flight operation situations. It is based on the assumption that cooperation among all participating operators achieves positive effect on CDM operation. The aim of the research is to identify, how factors driving cooperative behaviour are established in flight operation situations during day-today HHI at action level. Obtained results are used to guide future CDM design with simulation software development and system behaviour simulation. In this paper, a cockpit survey is introduced which examines two highly dynamic flight operation situations. Both situations are usually time constrained, change quickly and require synchronous human-human cooperation between pilots and multiple other operators. The first one, turn-round operation, involves HHI with information sharing via face-to-face or technological means and HHI with task/decision making distribution between pilots and other operators. The second one, the flight operation itself, involves HHI with information sharing only via technological means and HHI with task/decision making distribution between pilots and other operators.
