Air pollution is one of the main factors affecting human health. Air quality is especially important in the tourist areas developed with facilities for outdoor activities. During the winter season of 2017/2018, the concentrations of particulate matter (PM10, PM2.5, PM1), CO, O3, and NO2 were studied in 12 attractive tourist villages in the surroundings of the Czorsztyn Reservoir in southern Poland. Air pollutant measurements were performed continuously, using a single ground-based Alphasense air sensor. Our assessment of human health risk (HHRA), arising from inhalation exposure to air contaminants, was calculated for both local inhabitants and tourists, based on actual measured values. It was found that pollutant concentrations exceeded both permissible and recommended levels of PM10 and PM2.5. The mean total noncarcinogenic risk values were equal to 9.58 (unitless) for adults and 9.68 (unitless) for children and infants, under the resident exposure scenario. However, under the tourist exposure scenario, the mean total risk was equal to 1.63 (unitless) for adults and 1.64 (unitless) for children and infants. The risk to tourists was lower than that to inhabitants due to shorter exposure times. The target non-carcinogenic value of 1, calculated for PM10, PM2.5, and NO2, was significantly exceeded in total risk, under the residential exposure scenario, in reference to all the local subpopulations. In the majority of the investigated locations, the total risk exceeded the value of 1, under the tourist scenario, for all the subpopulations analysed. PM2.5 was recognised to be the most important contaminant in our risk analysis, in view of its share in the total risk value.

This paper describes the implementation of the distributed INRED system running in a real industrial environment, with a set of intelligent tools and a workflow system. The INRED-Workflow system, being the key components of the INRED system, provides the infrastructure for process automation. Participants of the (service) processes, managed by INRED-Workflow, are controlled by the system and other process participants, such as quality managers and technologists, at every stage of the performed service procedures. All data gathered from the service processes is stored in the System Knowledge Repository (SKR) for further processing by using advanced algorithms. The INRED-Workflow system uses the so-called Smart Procedures, which allows easy implementation of newly defined algorithms based, among others, on machine learning.

The article presents a model of pedestrian dynamics based on Cellular Automata, dedicated especially for high density conditions. Using the proposed representation, it is possible to map different behaviors of agents in various conditions. The article describes mechanisms of a pedestrian’s movement for different pedestrian’s shapes when a pedestrian occupies multiple cells, compared to the classical representation where a pedestrian occupies a single square cell. A greater number of cells per pedestrian can describe a pedestrian with e.g. a backpack, a suitcase on wheels, or on a bicycle more precisely than when s/he is represented by one cell. More accurate discretizations are particularly useful when high density of pedestrians occurs. The article focuses on the following aspects of a pedestrian’s movement: changing direction, movement speed, a passing scheme, and an overtaking scheme.

The article presents a new method of modeling the spread of fire using Cellular Automata based on 3D mesh. The models based on different heat transport mechanisms were used in the study, including conductivity, convection and thermal radiation. General mechanisms of fire spread are exemplified by a fire inside a building. The tests of the created simulator for fire in rooms were conducted, and the reference point was the known simulator based on CFD, namely FDS Fire Dynamics Simulator.

The aim of this study was to assess air quality by using medium-cost sensors in recreational areas that are not covered by permanent monitoring. Concentrations of air pollutants PM2.5, PM10, PM1, CO, O 3 , NO 2 in the Niedzica recreational area in southern Poland were obtained. The research revealed that in cold weather, particulate matter concentrations significantly exceeded acceptable levels determined for PM2.5 and PM10. The most important factor that affects air quality within the studied area seems to be the combustion of poor quality fuels for heating purposes. The information obtained by the research presented could be a useful tool for local authorities to make environmental decisions, based on the potential health impacts of poor air quality levels on the population.

The paper presents the method of identifying the initial pool of request-response pairs for Active Protocol Discoverer. This method is suitable for the bottom-up form of protocol discovering, in which the samples of requests are generated, and the high order form (e.g. grammar) of protocol description is created on the basis of these samples. The method is based on the evolutionary computation approach similar to linear genetic programming, in which particular requests are treated as individuals (programs) with different lengths.

The paper presents a proposition of a system of protocol discovering (Protocol Discoverer) developed on the basis of Grammatical Evolution techniques. Unlike numerous other solutions based solely on observing messages between participants of a conversation, our Protocol Discoverer is an active participant which generates messages and sends them to the system for which the protocol is to be identified. This solution allows not only for identifying typical behaviors of participants within a protocol, but also for finding anomalous behaviors (the ones which normally do not occur between participants using a defined protocol). In order to generate the description of a protocol in the form of a context-free grammar, the solution presented in the article is based on the evolutionary approach using Grammatical Evolution by Grammatical Evolution. Universal grammar is the basis for creating evolutionary solution grammars which describe particular pairs of requests-responses appearing in the protocol.

The paper focuses on the evaluation of effectiveness of a number of algorithms used to assess text similarity. The purpose of such evaluation is to determine the best methods for comparing and identifying near-identical web pages. Such comparison of web pages is in turn a prerequisite for building new automated testing tools and security scanners. The goal is to build scanners that will be able to automatically test the web application behavior for a large range of supplied parameters (known as fuzzing). Such testing requires massive generation and processing of requests, which in turn require fast page comparison methods. The similarity comparison is performed on a shortened, tokenized version of web pages, using a test set of pages downloaded from popular websites. A methodology for the evaluation of similarity metrics is proposed, together with a quality metric for the intended task. Several tokenization strategies are also tested and their impact on the final result is assessed.

This paper discusses selected aspects of evolutionary search algorithms guided by grammars, such as Grammar Guided Genetic Programming or Grammatical Evolution. The aim of the paper is to demonstrate that, when the efficiency of the search process in such environment is considered, it is not only the language defined by a grammar that is important, but also the form of the grammar plays a key role. In the most common current approach, the person who sets up the search environment provides the grammar as well. However, as demonstrated in the paper, this may lead to a sub-optimal efficiency of the search process. Because an infinite number of grammars of different forms can exist for a given language, manual construction of the grammar which makes the search process most effective is generally not possible. It seems that a desirable solution would be to have the optimal grammar generated automatically for the provided constrains. This paper presents possible solutions allowing for automatic grammar induction, which makes the search process more effective.
