    GNSS meteorology
    Opis:
    The Global Navigation Satellite System (GNSS) can be used to determine accurate and high-frequency atmospheric parameters, such as Zenith Total Delay (ZTD) or Precipitable Water Vapour (PW), in all-weather conditions. These parameters are often assimilated into Numerical Weather Prediction (NWP) models and used for nowcasting services and climate studies. The effective usage of the ZTDs obtained from a ground-based GNSS receiver’s network in a NWP could fill the gap of insufficient atmospheric water vapour state information. The supply of such information with a latency acceptable for NWP assimilation schemes requires special measures in the GNSS data processing, quality control and distribution. This study is a detailed description of the joint effort of three institutions – Wrocław University of Environmental and Life Sciences, Wrocław University, and the Institute of Meteorology and Water Management – to provide accurate and timely GNSS-based meteorological information. This paper presents accuracy analyses of near real-time GNSS ZTD validated against reference ZTD data: the International GNSS Service (IGS) from a precise GNSS solution, Weather Research and Forecasting (WRF) model, and radiosonde profiles. Data quality statistics were performed for five GNSS stations in Poland over a time span of almost a year (2015). The comparison of near real-time ZTD and IGS shows a mean ZTD station bias of less than 3 mm with a related standard deviation of less than 10 mm. The bias between near real-time ZTD and WRF ZTD is in the range of 5-11 mm and the overall standard deviation is slightly higher than 10 mm. Finally, the comparison of the investigated ZTD against radiosonde showed an average bias at a level of 10 mm, whereas the standard deviation does not exceed 14 mm. Considering the data quality, we assess that the NRT ZTD can be assimilated into NWP models.

    Opis:
    Interpolation of precipitation data is a common practice for generating continuous, spatially-distributed fields that can be used for a range of applications, including climate modeling, water resource management, and agricultural planning. To obtain the reference field, daily observation data from the measurement network of the Institute of Meteorology and Water Management – National Research Institute was used. In this study, we compared and combined six different interpolation methods for daily precipitation in Poland, including bilinear and bicubic interpolation, inverse distance weighting, distance-weighted average, nearest neighbor remapping, and thin plate spline regression. Implementations of these methods available in the R programming language (e.g., from packages akima, gstat, fields) and the Climate Data Operators (CDO) were applied. The performance of each method was evaluated using multiple metrics, including the Pearson correlation coefficient (RO) and the correspondence ratio (CR), but there was no clear optimal method. As an interpolated resulting field, a field consisting of the best interpolations for individual days was proposed. The assessment of daily fields was based on the CR and RO parameters. Our results showed that the combined approach outperformed individual methods with higher accuracy and reliability and allowed for generating more accurate and reliable precipitation fields. On a group of selected stations (data quality and no missing data), the precipitation result fields were compared with the fields obtained in other projects-CPLFD-GDPT5 (Berezowski et al. 2016) and G2DC-PLC (Piniewski et al. 2021). The variance inflation factor (VIF) was bigger for the resulting fields (~5), while for the compared fields, it was below 3. However, for the mean absolute error (MAE), the relationship was reversed - the MAE was approximately half as low for the fields obtained in this work.

    Opis:
    Understanding the impacts of pandemics on public health and related societal issues at granular levels is of great interest. COVID-19 is affecting everyone in the globe and mask wearing is one of the few precautions against it. To quantify people's perception of mask effectiveness and to prevent the spread of COVID-19 for small areas, we use Understanding America Study's (UAS) survey data on COVID-19 as our primary data source. Our data analysis shows that direct survey-weighted estimates for small areas could be highly unreliable. In this paper, we develop a synthetic estimation method to estimate proportions of perceived mask effectiveness for small areas using a logistic model that combines information from multiple data sources. We select our working model using an extensive data analysis facilitated by a new variable selection criterion for survey data and benchmarking ratios. We suggest a jackknife method to estimate the variance of our estimator. From our data analysis, it is evident that our proposed synthetic method outperforms the direct survey-weighted estimator with respect to commonly used evaluation measures.

    Opis:
    Regression methods are used for the valuation of real estate in the comparative approach. The basis for the valuation is a data set of similar properties, for which sales transactions were concluded within a short period of time. Large and standardized databases, which meet the requirements of the Polish Financial Supervision Authority, are created in Poland and used by the banks involved in mortgage lending, for example. We assume that in the case of large data sets of transactions, it is more advantageous to build local regression models than a global model. Additionally, we propose a local feature selection via regularization. The empirical research carried out on three data sets from real estate market confirmed the effectiveness of this approach. We paid special attention to the model quality assessment using cross-validation for estimation of the residual standard error.

    Opis:
    A geoid or quasigeoid model allows the integration of satellite measurements with ground levelling measurements in valid height systems. A precise quasigeoid model has been developed for the city of Krakow. One of the goals of the model construction was to provide a more detailed quasigeoid course than the one offered by the national model PL-geoid2011. Only four measurement points in the area of Kraków were used to build a national quasigeoid model. It can be assumed that due to the small number of points and their uneven distribution over the city area, the quasigeoid can be determined less accurately. It became the reason for developing a local quasigeoid model based on a larger number of evenly distributed points. The quasigeoid model was based on 66 evenly distributed points (from 2.5 km to 5.0 km apart) in the study area. The process of modelling the quasigeoid used height anomalies determined at these points on the basis of normal heights derived through levelling and ellipsoidal heights derived through GNSS surveys. Height anomalies coming from the global geopotential model EGM2008 served as a long-wavelength trend in those derived from surveys. Analyses showed that the developed height anomaly model fits the empirical data at the level of single millimetres – mean absolute difference 0.005 m. The developed local model QuasigeoidKR2019, similar to the national model PL-geoid2011, are models closely related to the reference and height systems in Poland. Such models are used to integrate GNSS and levelling observations. A comparison of the local QuasigeoidKR2019 and national PL-geoid2011 model was made for the reference frame PL-ETRF2000 and height datum PL-KRON86-NH. The comparison of the two models with respect to GNSS/levelling height anomalies shows a triple reduction in the values of individual quartiles and a mean absolute difference for the developed local model. These summary statistics clearly indicate that the accuracy of the local model for the city of Krakow is significantly higher than that of the national one.

    Opis:
    Cyber-attacks are increasing day by day. The generation of data by the population of the world is immensely escalated. The advancements in technology, are intern leading to more chances of vulnerabilities to individual’s personal data. Across the world it became a very big challenge to bring down the threats to data security. These threats are not only targeting the user data and also destroying the whole network infrastructure in the local or global level, the attacks could be hardware or software. Central objective of this paper is to design an intrusion detection system using ensemble learning specifically Decision Trees with distinctive feature selection univariate ANOVA-F test. Decision Trees has been the most popular among ensemble learning methods and it also outperforms among the other classification algorithm in various aspects. With the essence of different feature selection techniques, the performance found to be increased more, and the detection outcome will be less prone to false classification. Analysis of Variance (ANOVA) with F-statistics computations could be a reasonable criterion to choose distinctives features in the given network traffic data. The mentioned technique is applied and tested on NSL KDD network dataset. Various performance measures like accuracy, precision, F-score and Cross Validation curve have drawn to justify the ability of the method.

    Opis:
    Badania dotyczą alternatywnego podejścia do oceny jakości metod interpolacji niewielkich i zróżnicowanych zestawów danych. Podstawowa analiza statystyczna oparta na klasycznej walidacji krzyżowej nie zawsze daje jednoznaczne wnioski. W przypadku analizowanego zestawu danych (niezgodnego z rozkładem normalnym) trzy metody interpolacji zostały wybrane jako najlepsze (zgodnie z procedurą klasycznej walidacji krzyżowej). Niemniej jednak mapy powstałe na podstawie tych metod wyraźnie się od siebie różnią. To jest powód, dla którego dogłębna analiza statystyczna była konieczna. Zaproponowano alternatywne podejście do tego zagadnienia, które uwzględnia szersze spektrum parametrów opisujących badany zestaw danych. Głównym założeniem tej metodyki jest porównanie nie tylko odchylenia standardowego estymatora, ale również trzech dodatkowych parametrów. To powoduje, iż końcowa ocena jest znacznie dokładniejsza. Analizę wykonano za pomocą programu Surfer (Golden Software). Zapewnia on możliwość wykorzystania wielu metod interpolacji wraz z różnorakimi, regulowanymi parametrami.
    The research concerns an alternative approach to the evaluation of interpolation methods for mapping small and imbalanced data sets. A basic statistical analysis of the standard cross-validation procedure is not always conclusive. In the case of the investigated data set (which is inconsistent with normal distribution), three interpolation methods have been selected as the most reliable (according to standard cross-validation). However, maps resulting from the aforementioned methods clearly differ from each other. This is the reason why a comprehensive statistical analysis of the studied data is a necessity. We propose an alternative approach that evaluates a broadened scope of parameters describing the data distribution. The general idea of the methodology is to compare not only the standard deviation of the estimator but also three additional parameters to make the final assessment much more accurate. The analysis has been carried out with the use of Golden Software Surfer. It provides a wide range of interpolation methods and numerous adjustable parameters.

    Opis:
    Analysis of accidents has found driver distraction to be a significant cause of accidents on the highways [1]. Therefore, studying the causes of driver distraction that impact its risk level is needed for a better understanding of accident occurrences. There is general scarcity of research in this field with no established research framework to study driver distractions. This paper proposes a modular research framework for conducting a driver distraction study on Polish city highways. The framework contains guidelines for distraction studies for wide range of cost and time intervals such as a quick, low cost study like analysis of existing accident databases maintained by the cities to relatively higher cost, longer duration study involving field data collection, statistical modeling, and analysis. A city may choose one or more modules to suit their study requirements including statistical and simulation tools to assess and validate the historical or empirical result. The framework is based on the careful modifications and revisions of an earlier transit bus driver study conducted in the Commonwealth of Virginia, U.S.A., and results from this research are presented for purposes of illustration.

    In this paper we compare the following MERIS processors against sea-truthing data: the standard MERIS processor (MEGS 7.4.1), the Case 2 Regional processor (C2R) of the German Institute for Coastal Research (GKSS), and the Case 2Water Properties processor developed at the Freie Universit¨at Berlin (FUB). Furthermore, the Improved Contrast between Ocean and Land processor (ICOL), a prototype processor for the correction of adjacency effects from land, was tested on all three processors, and the retrieval of level 2 data was evaluated against sea-truthing data before and after ICOL processing. The results show that by using ICOL the retrieval of spectral reflectance in the open sea was improved for all processors. After ICOL processing, the FUB showed rather small errors in the blue, but underestimated in the red −34% Mean Normalised Bias (MNB) and 37% Root Mean Square (RMS). For MEGS the reflectance in the red was underestimated by about −20% MNB and 23% RMS, whereas the reflectance in the other channels was well predicted, even without any ICOL processing. The C2R underestimated the red with about −27% MNB and 29% RMS and at 412 nm it overestimated the reflectance with about 23% MNB and 29% RMS. At the outer open sea stations ICOL processing did not have a strong effect: the effect of the processor diminishes progressively up to 30 km from land. At the open sea stations the ICOL processor improved chlorophyll retrieval using MEGS from −74% to about 34% MNB, and TSM retrieval from −63% to about 22% MNB. Using FUB in combination with ICOL gave even better results for both chlorophyll (25% MNB and 45% RMS) and TSM (−4% MNB and 36% RMS) in the open Baltic Sea. All three processors predicted TSM rather well, but the standard processor gave the best results (−12% MNB and 17% RMS). The C2R had a very low MNB for TSM (1%), but a rather high RMS (54%). The FUB was intermediate with −16% MNB and 31% RMS. In coastal waters, the spectral diffuse attenuation coefficient Kd(490) was well predicted using FUB or MEGS in combination with ICOL (MNB about 12% for FUB and 0.4% for MEGS). Chlorophyll was rather well predicted in the open Baltic Sea using FUB with ICOL (MNB 25%) and even without ICOL processing (MNB about 15%). ICOL-processed MEGS data also gave rather good retrieval of chlorophyll in the coastal areas (MNB of 19% and RMS of 28%). In the open Baltic Sea chlorophyll retrieval gave a MNB of 34% and RMS of 70%, which may be due to the considerable patchiness caused by cyanobacterial blooms. The results presented here indicate that with the MERIS mission, ESA and co- workers are in the process of solving some of the main issues regarding the remote sensing of coastal waters: spatial resolution; land-water adjacency effects; improved level 2 product retrieval in the Baltic Sea, i.e. the retrieval of spectral reflectance and of the water quality products TSM and chlorophyll.

    Opis:
    The review article is an attempt to present the issue of including respondents' inclusions in the process of qualitative pedagogical research. The problem is not often discussed in the literature in the field of pedagogical research methodology, while the dynamically developing philosophy of qualitative research in this area (participatory paradigms) proves the need to discuss the methods and possibilities of coop-eration between the researcher and the respondents. The theoretical aim of the authors is to define the described issue, whereas the practical goal of this article is to show how to include respondents in the active participation in research, and legal issues related to their participation. The latest Polish and English-language literature and practical experience indicate the existence of a number of inclusive ways of data collection, analysis and interpretation in cooperation with the surveyed entities. The article may be an inspiration for a pedagogue - teacher - educator - tutor who carries out diagnostic (research) tasks in the process of educating his pupils.
    Artykuł ma charakter przeglądowy i prezentuje problem włączania badanych do jakościowych badań pedagogicznych. Problem ten nie jest często poruszany w literaturze z obszaru metodologii badań pedagogicznych, tymczasem dynamicznie rozwijająca się filozofia badań jakościowych w tym zakresie (paradygmaty partycypacyjne) świadczy o konieczności dyskutowania o sposobach i możliwościach współpracy badacza z badanymi. Cel poznawczy artykułu to zdefiniowanie opisywanego zagadnienia i tym samym wzbogacenie teorii badań pedagogicznych, natomiast ukazanie sposobów włączania pod-miotów do aktywnego udziału uczestników w badaniach oraz prawnych standardów związanych z ich partycypacją stanowi praktyczny cel artykułu. Najnowsza literatura polsko- i anglojęzyczna oraz doświadczenia praktyczne badaczy jakościowych wskazują na istnienie inkluzyjnych sposobów gromadzenia danych, ich analizy i interpretacji we współpracy z badanymi podmiotami. Artykuł może być inspiracją dla pedagoga-nauczyciela-edukatora-wychowawcy, który realizuje zadania diagnostyczne (badawcze) w procesie kształcenia i wychowania swoich uczniów i wychowanków.

    Centralna Platforma archiwizująca strony internetowe rządu Holandii
    Opis:
    The National Archives of the Netherlands, as a permanent government agency and official archive for the central government (ministries and their agencies), has the legal duty, laid down in the Archiefwet, to secure the future of government records. Within this context, our role does not involve actively forming a collection of archived websites through selecting and harvesting these ourselves. This is a key difference between us and other national archives, national libraries and other (inter-)national heritage institutions. guidelines and a central platform for archiving government websites. Such a mandate requires an environment in which the processes, in relation to one another, can take place in a controlled manner. A significant part of making it happen was the effort we’ve put (and continue to do so) into advising the producers of records – ministries and their agencies – as to how they should create, and eventually transfer, archived public websites that are a specific form of government records. One example of the type of support we offer was a very well received set of guidelines on archiving websites that we issued in 2018. Those guidelines were also used as part of the requirements in a public European tender (2021). The objective of the tender: implementation of a central harvesting platform to harvest approximately 1500 public websites of the Central government. This article will also present our experiences and insights into integrating the processes of ingestion, storage, management and preservation of and providing access to archived public websites of the Dutch Central government into the existing infrastructure and workflows of our trusted digital repository (e-depot in short).  
    Archiwum Narodowe Holandii i archiwizacja rządowych stron internetowych Archiwum narodowe Holandii, jako stała agencja rządowa i archiwum rządu centralnego (ministerstw i ich agencji), ma prawny obowiązek zabezpieczania akt rządowych. Rola archiwum nie polega na aktywnym tworzeniu kolekcji zarchiwizowanych stron internetowych poprzez ich samodzielne wybieranie i gromadzenie. Różni się tym od innych narodowych archiwów, bibliotek i innych (między-)narodowych instytucji dziedzictwa zajmujących się archiwizacją stron internetowych. Archiwum w swoich działaniach skupia się na doradzaniu twórcom dokumentacji – ministerstwom i ich agencjom – w kwestiach tworzenia i przekazywania rejestrów rządowych w formie zarchiwizowanych, publicznych stron internetowych. Jednym z przykładów tego typu wsparcia było wydanie w 2018 r. dobrze przyjętych wytycznych dotyczących archiwizacji stron internetowych. Zostały one także wykorzystane jako część wymagań europejskiego przetargu publicznego w 2021 r., dotyczącego utworzenia centralnej platformy mającej pozyskać około 1500 publicznych stron internetowych rządu centralnego Holandii. W artykule zostaną również przedstawione nasze doświadczenia i spostrzeżenia dotyczące integracji procesów pozyskiwania, przechowywania, zarządzania, zabezpieczania i zapewnienia dostępu do zarchiwizowanych publicznych stron internetowych holenderskiego rządu centralnego z istniejącą infrastrukturą oraz zarządzaniem danymi w repozytorium cyfrowym Archiwum narodowego Holandii (w skrócie w-depot).
