Opis:
The paper presents the analysis and discussion of gender recognition based on human face picture. The research combines different features selection techniques with the set of softcomputing classifiers. We are looking for not very complicated, fast and sensitive approach to create the theoretical basis for real safety systems where the correct “on-line” gender recognition is necessary. We start from the already known differences between the female and male face. This is the key point to tune the preprocessing mechanisms. We propose the quite classic classifiers, but we focus on sensible correlation between the feature extraction and the actual classification. The significant set of the results are discussed and the best solutions are pointed. All tests were realised based on the well known base of face pictures with added set of our own collection. The proposed solution can be an essential tool for the monitoring systems, safety guards and systems to point the dangerous situations based on video data.

Opis:
In the analysis of the operation of critical infrastructure systems it is important to perform the analysis of the safety of the operation. The daily operation of such systems is inherently associated with the occurrence of various types of random undesirable events. Therefore, in the paper the matrix and logical trees methods used in the analysis of the risk of threats in critical infrastructure systems within the Baltic Sea, were presented. The analysis and assessment of the protection of technical system was performed using the FMEA method (Failure Mode and Effect Analysis). As to analyse the cause and effect of undesirable events the method of Bayes' theorem and Java Bayes program were implemented, which allows to identify the probability of the event occurrence.

Opis:
Hybrid systems (HS) are roughly described as a set of discrete state transitions and continuous dynamics modeled by differential equations. Parametric HS may be constructed by having parameters on the differential equations, initial conditions, jump conditions, or a combination of the previous ones. In real applications, the best solution is obtained by a set of metrics functional over the set of solutions generated from a finite set of parameters. This paper examines the choice of parameters on delta-reachability bounded hybrid systems. We present an efficient model based on the tool pHL-MT to benchmark the HS solutions (based on dReach), and a non-parametric frontier analysis approach, relying on multidirectional efficiency analysis (MEA). Three numerical examples of epidemic models with variable growth infectivity are presented, namely: when the variable of infected individuals oscillates around some endemic (non-autonomous) equilibrium; when there is an asymptotically stable non-trivial attractor; and in the presence of bump functions.

Opis:
National safety system is an important element ensuring safe functioning of the state and its citizens. For this reason it is and has to be subjected to permanent identyfication and analysis covering various aspects. Identyfication in the field of real and possible treats to national safety is increasing. For the overall observation of how national safety system operates, the best seems to be a system analysis, which also make it possible to search for, construct and evaluate solutions for the near and further future in a more rational way.

Opis:
This article deals with a dynamic simulation of the movement and fall of persons working at a height, using the rope belaying system. The input data, which are necessary for a created simulation model, were obtained from experimental measurements realised from the concrete belaying system. The simulation analyses were performed for three different values of the rope pre-load level. Consequently, the outputs from the simulations presented in this article were applied in a real design proposal of the rope anchoring arrangement for a horizontal belaying system.

Opis:
Aviation is the fastest growing but also the safest mode of transport. International aviation organizations give the highest priority to safety while creating aviation regulations. Therefore, a safety management system (SMS) has been created. Two approaches to assuring safety in aviation may be distinguished: Safety-I and Safety-II. Safety-I is the standard approach, focused on processing the information about malfunctioning features and system elements. On the other hand, Safety-II is a new approach to safety management, based on identifying the elements or functions of the system that work properly, which enables the system to confirm resilience to undesirable effects. One of the methods utilized for the Safety-II approach in order to study complex sociotechnical systems is the FRAM (functional resonance analysis method). The method is focused on analysing daily activities in various conditions in order to create a model of work performance. The models created based on the FRAM can be used for risk analysis, accident investigations and predicting possible future events affecting aviation safety. This method allows us to simulate system constraints and uncertain states. It can also be used as support for the air traffic safety management processes based on the Safety-II approach. The following article presents a developed FRAM model for the transfer of control over aircraft. This model constitutes an example of a coordination scheme limited to basic activities of air traffic control (ATC) services, providing a general framework for the construction and operation of the FRAM model.

Opis:
Warunkiem zrównoważonych form rozwoju infrastruktury miejskiej, uwzględniających zarówno komfort, bezpieczeństwo oraz ład przestrzenny jest podejście wielokierunkowe, łączące to, co wynika z potrzeb, ale i obowiązków mieszkańców aglomeracji, a także w sposób harmonijny wpisuje się w otaczający krajobraz kulturowy. Konieczne jest, zatem opracowanie kompleksowych przedsięwzięć w zakresie planowania i projektowania przestrzeni miejskich. Spójne i kompleksowe wdrożenie koncepcji w zakresie bezpieczeństwa ruchu drogowego nie tylko zmniejszy liczbę wypadków, ale powinno także przyczynić się do poprawy jakości i warunków życia w mieście oraz bardziej efektywnego podziału przestrzeni miejskiej i lepszego przepływu ruchu pieszych, czy rowerzystów. W pracy odniesiono się do koncepcji planowania infrastruktury komunikacyjnej opartej na zasadach strefowania oraz wspólnych przestrzeni, a także kształtowania terenów zieleni.
In order to achieve balanced forms of urban infrastructure, which ensure comfort, safety and spatial order, when designing new solutions it is necessary to adopt a multi-facet approach which will combine everything that the local residents need but will respond harmoniously to the existing cultural landscape. It is therefore necessary to work out complex undertakings for the sake of planning and developing urban space. Coherent and complex implementation of planned road safety conceptional works should not only reduce the number and weight of accidents but should also lead to improved quality of urban life and living conditions, more efficient division of the urban space, better flow of traffic of pedestrians and cyclists, changes in the behaviour of all road users, changes in the structure of transported cargos and more common use of safer means of transport. This paper deals with a concept of planning transport infrastructure based on the principle of establishing spheres and shared spaces as well as on greenery areas management.
