Normalized Systems (NS) enables sustainable software development and maintenance using code generation of evolvable information systems from models of so-called NS Elements. To promote semantic interoperability with other conceptual models, RDF and OWL technologies can be used for knowledge representation in NS as it is common within the Semantic Web and Linked Open Data domains. Previous research resulted in initial NS-OWL bi-directional transformation and a prototype tool for its execution. In this extended paper, these efforts are further elaborated into an evolvable solution based on NS Expanders. The transformation utilizes RDF to encode all domain-specific structural knowledge of an NS model to ensure bi-directionality. In addition, it also maps entities of NS metamodel to OWL concepts to serve as an ontology for underlying data. Because of the metacircular NS metamodel, any NS model including the metamodel itself, can be transformed. Moreover, the transformation of application data to or from RDF is also possible. Having the NS metamodel, NS models, and potentially also data in RDF opens further research possibilities in terms of analysis and integrations. The use of NS Expanders caused that the solution can be easily extended and refined, e.g. when the metamodel is updated. The results of our research are expected to help with the design of real-world information systems, including the NS tooling and the metamodel.

Nonribosomal peptides and polyketides are natural products commonly synthesized by microorganisms. They are widely used in medicine, agriculture, environmental protection, and other fields. The structures of natural products are often analyzed by high-resolution tandem mass spectrometry, which becomes more popular with its increasing availability. However, the characterization of nonribosomal peptides and polyketides from tandem mass spectra is a nontrivial task because they are composed of many uncommon building blocks in addition to proteinogenic amino acids. Moreover, many of them have cyclic and branch-cyclic structures. Here, we introduce MassSpecBlocks - an opensource and web-based tool that converts the input chemical structures in SMILES format into sequences of building blocks. The structures can be searched in public databases PubChem, ChemSpider, ChEBI, NP Atlas, COCONUT, and Norine and edited in a user-friendly graphical interface. Although MassSpecBlocks can serve as a stand-alone database, our primary goal was to enable easy construction of custom sequence and building block databases, which can be used to annotate mass spectra in CycloBranch software. CycloBranch is an open-source, cross-platform, and standalone tool that we recently released for annotating spectra of linear, cyclic, branched, and branch-cyclic nonribosomal peptides and polyketide siderophores. The sequences and building blocks created in MassSpecBlocks can be easily exported into a plain text format used by CycloBranch. MassSpecBlocks is available online or can be installed entirely offline. It offers a REST API to cooperate with other tools.

The Hicks induced innovation hypothesis states that a price increase of a production factor is a spur to the invention. We propose an alternative hypothesis restating that a spur to the invention requires not only an increase of one factor but also a decrease of at least one other factor to offset the companies’ cost. We illustrate the need for our alternative hypothesis in a historical example of the industrial revolution in the United Kingdom. Furthermore, we econometrically evaluate both hypotheses in a case study of research and development (R&D) in 29 OECD countries from 2003 to 2017. Specifically, we investigate the dependence of investments to R&D on the economic environment represented by average wages and oil prices using panel regression. We find that our alternative hypothesis is supported for R&D funded and/or performed by business enterprises while the original Hicks hypothesis holds for R&D funded by the government and R&D performed by universities. Our results reflect that the business sector is significantly influenced by market conditions, unlike the government and higher education sectors.

Automatic detection of objects in photos and images is beneficial in various scientific and industrial fields. This contribution suggests an algorithm for segmentation of color images by the means of the parametric mean curvature flow equation and CIE94 color distance function. The parametric approach is enriched by the enhanced algorithm for topological changes where the intersection of curves is computed instead of unreliable curve distance. The result is a set of parametric curves enclosing the object. The algorithm is presented on a test image and also on real photos.

The outbreak of the global coronavirus pandemic worsened the conditions for teaching, and it was necessary to teach students to use technologies and tools of remote communication, such as Skype, Google meets or today’s most popular software from Microsoft - MS Teams. Since we primarily teach agile project management using practical methods, specifically games, it was necessary to invent and design a game that can be played through remote communication channels, not only in classes with students’ physical presence. The game was designed in ADLM software, which stands for Application Life-cycle Management, called JunoOne. Through this tool, the course of the entire project (agile game) will be recorded in the game, and students will be able to try not only the style of agile project management in the Scrum framework but also in the real tool used in practice. This paper’s main goal is to present the created agile game in a real tool and the concept of how to play the game remotely. Unfortunately, the game as such has not yet been played due to the bad pandemic situation.

Since its inception in 2007, DBpedia has been constantly releasing open data in RDF, extracted from various Wikimedia projects using a complex software system called the DBpedia Information Extraction Framework (DIEF). For the past 12 years, the software received a plethora of extensions by the community, which positively affected the size and data quality. Due to the increase in size and complexity, the release process was facing huge delays (from 12 to 17 months cycle), thus impacting the agility of the development. In this paper, we describe the new DBpedia release cycle including our innovative release workflow, which allows development teams (in particular those who publish large, open data) to implement agile, cost-efficient processes and scale up productivity. The DBpedia release workflow has been re-engineered, its new primary focus is on productivity and agility, to address the challenges of size and complexity. At the same time, quality is assured by implementing a comprehensive testing methodology. We run an experimental evaluation and argue that the implemented measures increase agility and allow for cost-effective quality-control and debugging and thus achieve a higher level of maintainability. As a result, DBpedia now publishes regular (i.e. monthly) releases with over 21 billion triples with minimal publishing effort.

In this contribution, we investigate the incompleteness problem in textual requirements specifications. Missing alternative scenarios are one of the incompleteness sources, i.e., descriptions of processing in the cases when something runs in another way as expected. We check the text of requirements specification using linguistic patterns, and we try to reveal scenarios and alternative scenarios. After that process is finished, we decide whether the set of alternative scenarios is complete. As a result, we generate warning messages. We illustrate our approach with examples.

Knowledge representation in OWL ontologies gained a lot of popularity with the development of Big Data, Artificial Intelligence, Semantic Web, and Linked Open Data. OWL ontologies are very versatile, and there are many tools for analysis, design, documentation, and mapping. They can capture concepts and categories, their properties and relations. Normalized Systems (NS) provide a way of code generation from a model of so-called NS Elements resulting in an information system with proven evolvability. The model used in NS contains domain-specific knowledge that can be represented in an OWL ontology. This work clarifies the potential advantages of having OWL representation of the NS model, discusses the design of a bi-directional transformation between NS models and domain ontologies in OWL, and describes its implementation. It shows how the resulting ontology enables further work on the analytical level and leverages the system design. Moreover, due to the fact that NS metamodel is metacircular, the transformation can generate ontology of NS metamodel itself. It is expected that the results of this work will help with the design of larger real-world applications as well as the metamodel and that the transformation tool will be further extended with additional features which we proposed.

Nowadays, open-source graph databases do not include an inherent mechanism for data relocation that would be based on their usage. They often do not offer even appropriate monitoring that could help to make such a decision. Information about data utilization could, however, work as an input to some decision- making process about more suitable data regrouping that could be much more efficient in terms of intra-network communication. Therefore, we created a module for the graph computational framework TinkerPop that logs traffic generated by the user queries. These logged records serve as an input for the algorithm of Adaptive Partitioning that we enhanced with better balancing, avoidance of local optima and the notion of weighted graphs. This approach yields a 70–80% improvement in intra-network communication, which is comparable to other methods, namely Ja-be-Ja, that offers similar results but has higher computational demands.

This bachelor thesis deals with the design of an application for parametric modelling of hall structures in the engineering software Tekla Structures. In the theoretical part of the thesis a research of available applications that are designed for parametric creation of building models is made. The output of the thesis is a functional prototype of a desktop application that allows to generate the main grid of the building model directly in the 3D scene of Tekla Structures software based on the input data provided by the user. The proposed user interface contributes to speed up the work when entering the necessary parameters. The implementation uses the .NET Framework platform in combination with the MVVM architecture, thanks to which the application has the potential for future extensions in the form of connecting other structural modelling software. The connection to Tekla Structures is implemented using its public API.

The master's thesis deals with the transformation of ontological conceptual models into graph databases and with the implementation of related integrity constraints. At first, the thesis analyzes the suitability of several different graph database systems and justifies the choice of the Neo4j graph database as the most suitable one for the given purpose. Next, it introduces a comprehensive procedure for the transformation of OntoUML diagrams into a list of specific integrity constraints and describes the precise implementation of these integrity constraints in the Neo4j. The mentioned procedure is subsequently used for the instantiation of an example OntoUML model. Instantiated model is also tested in order to verify the correctness of the transformation procedure. Finally, the thesis discusses the achieved results and addresses possible future work. As a result, this thesis shows that it is possible to instantiate a valid OntoUML model in a graph database, yet it is not possible to use the same principles of instantiation for all types of graph databases.

Dozens and possibly hundreds of textural features have already been introduced, but any comprehensive evaluation and comparison of the features is still lacking. We study and describe monospectral and multispectral features and based on this we create a general methodology for measuring the information quality of textural features. In this methodology, we classify features into categories, which creates a generalization layer that allows features to be evaluated generally and automatically. We will then incorporate this methodology in the creation of a multispectral textural benchmark with a web portal that allows experimentation with features. We will explain all phases of development from analysis, design of the user interface and its testing, to the actual implementation of the system. The created benchmark is made up of several components and can be expanded with other features, datasets for statistics, and last but not least, it is computationally scalable both vertically and horizontally.

This thesis provides an overview of modern immersive audio technologies and outlines why ambisonics is becoming the industry-standard spatial audio format for 360° video. An introduction to ambisonics theory is provided, and several important decoding techniques are described. A software solution is then presented, which implements automatic spatial panning of sounds in a DAW based on the 3D positions of objects (relative to the active camera) in the Blender scene. The implementation consists of two plugins - a Blender plugin to access the 3D scene data, and a VST ambisonic panner plugin that utilises said scene data to calculate the panning direction. Panning direction vectors are updated in real time using interprocess communication, allowing artists to preview the animation while simultaneously making adjustments to the audio, and vice versa. The presented solution is especially useful in producing spatial audio for 360° 3D animations, where it can help reduce the number of audio sources that have to be panned manually. It can however find a place in non-animated projects as well, where it can be used to visualise the movement of sound sources, and would allow to use Blender's advanced 3D animation toolset for animating sound source positions.

3D reconstruction, especially photogrammetry is a common way of acquiring static 3D models of the real world. There exist multiple software solutions performing photogrammetry that process overlapping images, for example, taken from multi-camera systems. This thesis aims to create a new pipeline that utilizes already existing photogrammetry software solutions and multi-camera systems. This pipeline starts with synchronized image acquisition of the scene and ends with visualization of an animated point cloud. To understand the demands and capabilities of photogrammetry, a custom multi-camera benchmark system was created. This system was used for photogrammetry experiments and as a starting point for the introduced pipeline. The results show that it is possible to create an animated point cloud even when using a low-cost multi-camera system, like ours created. Using this pipeline on high-end multi-camera systems may introduce new interesting dynamic visualization of captured scene.

The COVID-19 pandemic led to increasing demand for real estate, mainly for those in cities rich in civic amenities. Finding the right real estate property without any domain insights is difficult. Creating a real estate portal with more than just a base of advertisement listings can require the use of proprietary technologies, which often do not allow storing information for later usage and thus results in the state known as the vendor locking. This thesis proposes an alternative way of creating a web-based scalable application using open source technologies powered by a triple-store database which enables the potential of the linked data.

A Blockchain smart contract (SC) is an emerging technology that has the potential to revolutionize the practice of conducting legal contracts. The benefits of SC include, for example, the opportunity to eliminate the need for third-party authorities. However, one of the challenges associated with smart contracts, stalling their mass adoption, is the complex, highly technical method of creating them. DasContract is an ongoing research project that aims to address this challenge by defining a visual domain-specific language (DSL) that can be converted into executable smart contract code. This thesis contributes to the research project by designing and implementing a web application in the Blazor WebAssembly framework, which allows users to visually model smart contracts using the DasContract DSL. The thesis also explores the possibilities of deploying the implemented client-side Blazor web application as a standalone multi-platform application. The editor is fully open-source and is currently being utilized for conducting further SC research.

This thesis covers the software design and realization of the Trackman service in the integration platform, Integromat. Trackman is a key component of the internal monitoring system of Integromat, and also plays a major role in the further distribution of collected data on the platform. The goal was to design the whole architecture of the service, mainly the database model and architecture of the application layer in JavaScript, as well as designing the communication between Trackman and third-party services while leveraging the existing integrations that are already offered by Integromat, and finally implementing the whole solution. The database layer is built on top of the PostgreSQL database management system and uses the Stored Procedures pattern. The application layer is then coded in JavaScript and thanks to the internal libraries of Integromat, it offers a high level of data abstraction and a wide range of possibilities for data transformation. At the time of finishing this thesis, Trackman is already running in the production environment, serving roughly half a million requests a day.
