Music Genre Recognition in the Rough Set-Based Environment
PublikacjaThe aim of this paper is to investigate music genre recognition in the rough set-based environment. Experiments involve a parameterized music data-base containing 1100 music excerpts. The database is divided into 11 classes cor-responding to music genres. Tests are conducted using the Rough Set Exploration System (RSES), a toolset for analyzing data with the use of methods based on the rough set theory. Classification effectiveness...

Job Demands, Engagement, and Turnover Intentions in Polish Nurses: The Role of Work-Family Interface
PublikacjaBackground: Poland has lower ratios of employed registered nurses per 1,000 inhabitants than the EU average. Polish nurses work under miserable conditions without assisting personnel, and they reconcile their professional demands with responsibilities for their families; 96% of them are women. Rationale/Aims: This study uses Hobfoll’s conservation of resources (CORs) theory to explain the role of various resources in the improvement...

Kinetyka formowania się tlenku miedzi(I) na elektrodzie Cu w oparciu o badania impedancyjne
PublikacjaWykorzystano technikę Dynamicznej Elektrochemicznej Spektroskopii Impedancyjnej (DEIS) do wyznaczenia chwilowych widm impedancyjnych w zakresie potencjałów formowania się warstwy pasywnej tlenku miedzi (I) w roztworze 0.1M NaOH. Autorzy skupili się na określeniu charakteru zmian parametrów impedancyjnych towarzyszących powstawaniu monowarstwy Cu-OHads. Do analizy zastosowano elektryczny obwód zastępczy R(CR)(COR). Zmiany tych parametrów...

Music Data Processing and Mining in Large Databases for Active Media
PublikacjaThe aim of this paper was to investigate the problem of music data processing and mining in large databases. Tests were performed on a large data-base that included approximately 30000 audio files divided into 11 classes cor-responding to music genres with different cardinalities. Every audio file was de-scribed by a 173-element feature vector. To reduce the dimensionality of data the Principal Component Analysis (PCA) with variable...

A Surrogate-Assisted Measurement Correction Method for Accurate and Low-Cost Monitoring of Particulate Matter Pollutants
PublikacjaAir pollution involves multiple health and economic challenges. Its accurate and low-cost monitoring is important for developing services dedicated to reduce the exposure of living beings to the pollution. Particulate matter (PM) measurement sensors belong to the key components that support operation of these systems. In this work, a modular, mobile Internet of Things sensor for PM measurements has been proposed. Due to a limited...

Nanoparticle-assisted biohydrogen production from pretreated food industry wastewater sludge: Microbial community shifts in batch and continuous processes
PublikacjaBiohydrogen production from industrial waste has gained a significant attention as a sustainable energy source. In this study, the enrichment of biohydrogen production from pretreated dissolved air flotation (DAF) sludge, generated from food industry wastewater treatment plants, was investigated using SiO2@Cu-Ag dendrites cor- e–shell nanostructure (NS). The effect of NS on the changes of the microbial community and biohydrogen...

The work-family interface: Job demands, work engagement and turnover intentions of Polish nurses
PublikacjaA conflict between one's professional life and one's family life may lead to lower well-being both at work and home. Most nurses are women who have traditionally reconciled their professional life with family life. One aim of this study was to examine the relationships between the work-family conflict (WFC),the family-work conflict (FWC), and the perception of job demands (quantitative workload and interpersonal conflicts at work)....
