Pre-processing of heterogeneous data streams for internet of things applications
The rapid evolution of sensor technologies, particularly within the Internet of Things (IoT) domain, has led to an era dominated by massive real-time data flows. This transition resulted in the need for novel data processing methodologies that facilitate the shift from traditional offline batch analytics to agile real-time predictions and …
Optimization of ToF-SIMS depth profiling in low-pressure H2, C2H2, CO and O2 atmosphere
Time-of-flight secondary ion mass spectrometry (ToF-SIMS) is a versatile analytical method widely used in the field of surface science and thin films. Although it gives elemental, molecular, and isotopic information, it has a very low detection limit and high lateral resolution, is fast and works with all the vacuum-compatible samples, …
Characterization of constrained continuous multiobjective optimization problems
Despite the large volume of recently published papers in the field of constrained multiobjective optimization, the understanding and characterization of constrained multiobjective optimization problems (CMOPs) for benchmarking multiobjective evolutionary algorithms (MOEAs) and the related constraint handling techniques (CHTs) remain unsatisfactory. Therefore, selecting appropriate CMOPs for benchmarking is challenging and lacks …
Information spreading barriers in news
News spreads in many patterns, structures, and dynamics that change throughout time. For a variety of reasons, certain news is only covered in a particular area. Language, economy, geography, politics, time zone, and culture are just a few of the many barriers that prevent news from reaching a larger audience. …
Temperature fractionation of mercury in the cement production process
Cement production is one of the main contributors to mercury emissions in to the atmosphere. Many national and international legal i nstruments aim to control and reduce Hg emissions. Hg enters the cement production process as an impurity in fuels and raw materials, with the latter being the main source …
Development of sensitive electrochemical sensor for detection of gaseous H2O2
In recent decades, hydrogen peroxide (H 2 O 2 ) has attracted considerable attention as a n omnipresent analyte, finding applications in clinical studies/diagnos is , biology, environmental protection, atmospheric studies, homeland security, and various analytical methodologies . This dissertation provides valuable insights into three different types of electrochemical sensors …
Hybrid sol-gel coatings based on different acrylate derivatives for protection of aluminium alloy and steel against corrosion and biofouling
The subject of the doctoral dissertation is the development of coatings with improved protection of metals against corrosion and antifouling protection on structural steel S355 and aluminum alloy AA7075. S355 is a widely used metal in the construction, while AA7075 is mostly used in the transportation industry. Although they exhibit …
Characterization of Spirulina microalgae as a new alternative food source
A reduction in agricultural productivity associated with water scarcity and land degradation, combined with the growing world population and malnutrition highlights the need for new alternative food sources. In this challenging field, Spirulina microalgae emerges as a promising candidate thanks to its high nutritional value and beneficial effect on human …
Investigation of the environmental acceptability of geotechnical composites, made from different recycled materials investigation of the environmental acceptability of geotechnical composites, made from different recycled materials
Current and especially past industrial and mining activities, including underground and open pit mining, have often resulted in soil pollution that has become a global and alarming environmental problem. Among contaminants, heavy metals and metalloids are under environmental scrutiny due to their potential toxicity, persistence, and because they can be …
Validation of peptides as protein substrate models for specificity studies of cysteine cathepsins
Cysteine cathepsins are endosomal proteases that are involved in lysosomal protein degradation. Additionally, they engage in specific biological processes, like bone degradation (CatK), antigen presentation (CatS) and pro-hormone processing (CatV and CatL). Their enhanced activity was described in numerous pathological states, like cancer and viral activation, which made them promising …
