At present, several studies exist describing the relevance of human factor in air transport with main focus on pilots and flight safety. Within such studies, monitoring of physiological functions is used. There are lot of physiological parameters and methods of their assessment; however, they are mostly based on principles originating from clinical practice. Yet, sensitivity and specificity of these...
This paper deals with research of safety performance predictions to allow improved risk control in military. Safety performance is identified as appropriate tool to establish system-wide information on safety which can serve the decision making process on how to manage safety. The information contributes to better understanding of behavioural patterns in the controlled system and the ability to foresee...
This paper deals with functionality verification of satellite navigation system GPS-150 before its application for air traffic. The goal of this project was to verify GPS-150 properties with regard to its fundamental functionality — provision of navigation information during flight. Within the research, the main focused was placed on GPS-150 operation during specific flight conditions with acrobatic...
Mental disorders, such as schizophrenia, are accompanied by increased morbidity and mortality rates, potentially reducing the lifespan of patients by up to 10 years. Premature deaths in schizophrenia sufferers are caused mainly by cardiovascular diseases and complications related to excessive weight gain and type 2 diabetes mellitus. Gaining weight is, furthermore, often a side effect of medicine...
Atrial fibrillation ranks among the most common heart rhythm disorders. Considering the lack of any trusted method capable of foreseeing possible recurrence of atrial fibrillation after it has been terminated, nonlinear analyses of beat-to-beat heart rate variability demonstrate promising potential. This work focuses on verifying the capability of the nonlinear methods to differentiate patients with...
The work introduces a new means for quantification of dynamic stability and upper limb movement as a whole during gait. Swinging arms during gait performed by the experiment volunteers, as a cyclic motion, was quantified using two parameters AH (the convex hull area) and already known to the medical community - ROM (range of motion) revealed a potential use of the former in the scientific community...
The article introduces a novel system for measuring locomotive response of small animals (specifically amphibians and reptiles) to change in their body orientation based on a camera system located on mechanical platform powered by a set of three actuators. The camera system consists of three cameras providing a record three anatomical angles of body segment movements in space. A gyro accelerometer...
The article focuses on a technique of gyroscope data processing and quantifying movement patterns of upper limb during walking. Four cheap gyroscopes were used. Using a novel method based on the trajectory length obtained by plotting shoulder and elbow joint angle vs. each other, provides information for a quantification of the complex arm movement as a whole in the sagittal plane. Two parameters...
The article presents a FlexiGuard modular biotelemetric system for real-time monitoring of special military units. The main focus of the system is on automated monitoring of special forces via parallel monitoring of each member of the special team individually, witch includes collecting sets of physiologic (or environmental) parameters. The systems consists of a set of sensors (for monitoring temperature,...
The article deals with the issue of rescuing people in aviation using rescue parachutes, while providing basic information on rescue parachute systems for an aircraft and on emergency ejection seats. The success of an emergency abandonment using rescue parachutes is affected by the actual flight conditions as well as the way of emergency abandonment the aircraft as well. Defining suitable conditions...
Psychological discomfort and stress may negatively affect various work activities especially in professions that are directly responsible for the lives and health of human beings. We can find these kinds of professions mainly in civil aviation, specifically the profession of a pilot. Analysis showed, that the legislative requirements for the qualifications of a pilot, require only the competence for...
The objects of the study including determining the relationships between movements of upper extremities identifying joint angles using a fuzzy logic system (FS). The authors analyzed ranges of joint angles and simple rhythmical movement: swinging segments of walking subjects' arms moving in-phase (synchronously) or anti-phase (reciprocally), and designed fuzzy expert system which has never been described...
The most frequently used method for scratch test in the international standards is progressive loading scratch test mode. Although the mentioned standards to measure practical adhesion of nano and micro thin films require optical microscope with magnifications between 100× and 500×, not only the optical microscopes, but even the international standards are not usually and largely used to study new...
Heart rate is a parameter describing activity of human heart and its psycho-physiological character based on sympathovagal balance of autonomic nervous system, which could be instrumental for indicating stress in aircraft pilots. The assessment focuses on transition from the airplane's analog presentation of flight data to digital visualization (glass cockpit). The main objective was to examine heart...
Flying an aircraft requires a significant degree of coordination of upper and lower limbs. Such movements tend to be rather uncoordinated in the case of inexperienced pilots which results in inaccurate piloting. The aim of this study is to prove or disprove the dependence of the upper limb activity in relation to the aircraft steering during various actions which are required for precise maneuvering...
The article is dealing with the study of stability and posture by measuring and analyzing the angular movements of the head and shoulders. In neurological practice, however, this method of evaluating the relative angular movements of the head and shoulders is not a common practice. The objective of this study was to develop a method of precise measurement of relative angular movements of the head...
