This thesis presents the travelling salesman problem and the application of heuristics in ant colony optimization algorithms. The thesis also discusses the results of an experiment carried out to solve the travelling salesman problem using the ant colony system with different heuristics. An example is focused on heuristics application and comparison. © 2015 IEEE. Source

This paper tries to find the answers to the following questions: What does Situational Airworthiness (SA) truly mean from the viewpoint of the pilot ability to keep acceptable safety level on each phase of the aircraft mission execution? Which element of the aviation model has the highest influence on that pilot ability? Which sub-factors have the highest influence on the probability of achieving and maintaining an acceptable level of sub-areas of SA by the pilot during the preparation and execution of air missions? Moreover, the paper discusses sub-subjects as the definition of SA, relations between processes and the status of SA. The conclusions of the paper are partially based on the Authors’ research of the years 2012-2013. © 2015, University of Dubronvnik. All rights reserved. Source

Introduction. Aim of this study was the training effect evaluation on the Special Aviation Gymnastics Instruments (SAGI) on blood metallothionein (MT), zinc (Zn), copper (Cu), protein, neuron-specific enolase (NSE), and physical fitness in the examined cadets. Material and methods. The study comprised 55 cadets, aged 20, divided into two groups: examined group A (N=41) and control group B (N=14). In both groups, blood material was collected twice, i.e. before (baseline) and after training (series I), during (series II), and after completion of training on the SAGI (Series III). Blood serum MT, Zn, Cu, protein, and NSE were assayed with commercially available kits). Physical fitness was assessed with commonly used fitness tests. Results. A significant decrease in serum MT was noted in both groups in all three series of assays after training, except group B in series II. NSE significantly increased in group A in series II after training. NSE activity increased significantly in group B in series I and III. In both groups, a significant decrease in blood serum Zn was noted after training in series I and II. Serum Cu significantly decreased in group A in all three series of assays. Blood serum protein significantly decreased in group A in series III. In series II, blood serum protein increased significantly in both groups. The remaining values were not changed significantly. Conclusions. Training intensity on SAGI lowered serum MT levels after training in comparison with the control group. This might be associated with Zn, Cu, and protein metabolism. Source

Artificial Satellites

The GNSS standard positioning solution determines the coordinates of the GNSS receiver and the receiver clock offset from measurements of at least four pseudoranges. For GNSS positioning, a direct solution was derived for five and ten observed satellites without linearisation of the observation equations and application of the least squares method. The article presents the basic principles of methods for solving the positioning problem, the formulas and their derivation. The numerical examples with simulated pseudorange data confirm the correct performance of the proposed algorithm. The presented algorithms should be further tested with real measurements in other domains of positioning and navigation as well. Source

The article discusses the influence of pilot’s knowledge, skills, experience, as well as the influence of technical and environmental factors on pilot’s ability to build a proper Situational Awareness (SA) state during an aviation operational activity. Moreover, the decision-making process and SA process were defined, and their dependence from the perspective of some aspects of abilities presented by pilot as well. Authors’ conclusions are based mainly on their own research supported by results of research available in the specialist literature. © 2015. University of Defence. All Rights Reserved. Source
