Pilot Induced Oscillations (PIO) are described as pilot-aircraft dynamic couplings which can lead to instability in an otherwise stable system. Previous and ongoing research has attempted to explain, predict, and avoid such oscillations. In contrast to other research, this effort backs away from pilot models and PIO avoidance and focuses on the characteristics of the pilot before, during, and a...

The equation of state Soave-Redlich-Kwong (SRK) and its modification (predictive SRK or PSRK) are applied to simulate multicomponet distillation, which separate main component of spearmint essential oil. The simulation model is based on bubble point method, and the Wang-Henke algorithm. Spearmint essential oil is considered in the study and the original experimental data were obtained f...

In this paper, we propose the analytical approach for amplify-andforward (AF) relay networks with pilot symbol assisted-channel estimation (PAS-CE) over quasi-static Rayleigh fading channels. Moreover, the accuracy of the channel estimation process is verified based on the number of pilot symbols and the accuracy of the derived average symbol error rate (ASER) expression of M-ary phase shift ke...

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 identify to the species level at sea; therefore, some of the descriptive material below refers to Globicephala spp., and is identified as such. The spe...

This paper studies the problem of channel estimation for the downlink in broadband LTE communications. A Kalman Filter is used to combine channel soundings made with pilot tones that are deployed at different times and in different frequency bands on a pre-selected pattern. This Kalman filter is presented in a form directly suitable for implementation as a periodically time varying filter, in t...

1. Auriculotherapy was effective in relieving the symptoms of constipation and improving quality of life for elderly people. 2. Auriculotherapy had a significant time effect in relieving symptoms of constipation, a greater reduction in scores for symptoms of constipation and quality of life, and an increased number of bowel movements per week, compared with controls. 3. The methodology of this ...

Task management (TM) is always performed on the flight deck, although not always explicitly, consistently, or rigorously. Nowhere is TM as important as it is in dealing with non-normal situations. The objective of this study was to analyze pilot TM behavior for non-normal situations. Specifically, the study observed pilots’ performance in a full workload environment in order to discern their TM...

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 considered ...
