Pilot survey of physicians on the system of assigning professional grades
Medicine of Extreme Situations, 2023Stagnation of the institution of assigning professional grades (categorization) draws increasing attention to the study of the opinions of physicians aimed at understanding and addressing the issues of this system. The study was aimed to get an estimate of the categorization system, the need for and directions of its transformation from physicians. The

Pilot Assignment to Ships in the Sea of Bothnia
2010The Maritime Administration in Sweden initiated a study on the best allocation of pilots and its impact on costs and service levels. Pilots are required to guide ships from and to ports along the shipping fairways between the ports and open sea. Transports to and from rendezvous points at sea are made by small vessels. Normally the pilots are qualified

Pilot assignment for PTS-OFDM with channel estimation for PAPR reduction
2016 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS), 2016The partial transmit sequence (PTS) technique is an effective method for the peak-to-average power ratio (PAPR) reduction of orthogonal frequency division multiplexing (OFDM) signals. Recently, applying channel estimation to PTS-OFDM with different pilot assignment schemes were proposed for removing the requirement of transmitting the side information (

An Innovative Pilot Assignment Technique for Pilot Contamination Suppression in TDD Massive MIMO
2018Time division duplex (TDD) massive multiple-input multiple-output (massive MIMO) has been regarded as a fantabulous technology for fifth generation wireless cellular networks (5G) to improve spectral efficiency (SE) and network performance using tens of hundreds of antennas and terminals attached to the base station (BS). On the other hand, the concept

Risk Analysis
AbstractHumans’ risk perception has been recognized as a significant factor affecting behavior safety. In the aviation domain, the two different roles of crews in the cockpit—pilot flying (PF) versus pilot monitoring (PM)—are responsible for different tasks. However, little is known about how role assignment shapes pilots’ perceived risk. We designed a

A Dynamic Optimization based Algorithm for Pilot Assignment in Massive MIMO.
J. Inf. Sci. Eng., 2023In this study, we propose an efficient algorithm for the optimization of pilot assignment to reduce pilot contamination in multi-cell multi-user massive multiple-input multiple-output (MIMO) systems. The object function of the proposed optimization approach is based on the cumulative average uplink Signal to Interference plus Noise Ratio (SINR) values.

Optimal Personnel Assignment: An Application to Air Force Pilots
Military Psychology, 1995Abstract : A study was conducted to examine the potential utility of optimally assigning Air Force pilots to training tracks without benefit of actual training outcomes. The resulting assignment solution indicated that (a) there was sufficient agreement among pilots to form coherent selection policies that differed across types of aircraft, and (b ...

Location-aware channel estimation and pilot assignment for massive MIMO
2014 International Workshop on High Mobility Wireless Communications, 2014A location-aware channel estimation algorithm is proposed for massive multiinput multi-output (MIMO) systems, to reduce the inter-cell interference caused by pilot contamination. Specifically, by utilizing the property of the steering vector, a fast Fourier transform based post-processing is introduced after the conventional pilot-aided channel ...
