Summary
Exploring ways to control the virtual environment is a popular goal of many human-computer interaction researchers. One of the approaches is using Leap Motion optical sensors, developed specifically to track hand and finger movements. The bachelor thesis focuses on utilizing Leap Motion sensors in real-time gesture recognition using neural networks. We used two layered bidirectional LSTM architecture to train static gestures along with dynamic gestures. The neural network was benchmarked on a publicly available ASL dataset acquiring 89.07% using 5-fold cross-validation on 200 epochs. The architecture was ultimately trained using our dataset of 3861 samples for real-time deployment. We demonstrated that the pre-trained model is sufficient to be integrated into other applications, and we also discussed the current state of the MultiLeap library, developed for hand detection using more than one Leap Motion sensor at once. We compared results of using multiple sensors with MultiLeap with results of using one sensor.

Summary
The thesis focuses on the analysis of methods used in recommender systems and specifically describes the k-nearest neighbors method. It defines metrics for evaluating recommender systems. Subsequently, it includes an analysis of data available from the systems at the Faculty of Information Technology, CTU in Prague. These data is preprocessed into a dataset containing student interactions with courses, on which the k-nearest neighbors method is used to recommend optional courses to each student based on similar students. Similar students are identified using Manhattan, Euclidean, and cosine distances. These distances are modified in the thesis to consider only the courses that both students actually enrolled in when comparing two students. Modified distance metrics are compared to original ones in the evaluation. The effectiveness of the system with different hyperparameters is evaluated using various metrics, with the cosine distance with 20 neighbors chosen the best combination.

Summary
The objective of this thesis is to create a system for the Haul agency, which would deal with the registration of goods.
In the first part of the thesis, an analysis is drawn up of the current state of the processes, which employees of the Haul agency use to register purchases and issues of goods. In the context of these processes, the existing programs, which deal with this kind of issues, are analyzed and the system requirements are defined.
After that, a design of the system is created, which primarily emphasizes the choice of satisfactory technologies and the need for operating with data, that are to be shared among multiple users. Based on this design the system is implemented.
In the end, the created system is subjected to the integration and user testing. As a part of the testing the Nielsen heuristic analysis of the created system has been carried out.
The resulting system allows employees of the Haul agency to process and analyze the data related to the registration of goods in a simple and organized manner.

Summary
With the rise of new technologies, digitalization is one of the ways how to save money, time and make work more efficient. One of the possible goals of digitalization is conversion of musical instruments into their virtual form.
In this work I summarized the state-of-the-art and also provided an analysis of the different approaches about creating virtual piano and virtual keyboards in general. Few techniques how hand and and finger gesture recognition is done nowadays are also described in this work as well as different approaches of several controllers.
Further, I compared two different approaches to hand and finger detection in order to create the virtual piano. One way is making virtual piano using only RGB camera. Second way is using Leap Motion Controller, which is an optical hand tracking module that captures movement of your hands. Further, I described advantages and disadvantages of these approaches and experimentally tested the accuracy.
In the thesis, in order to recognize finger location and predict tapping on the piano keys I am using deep convolutional neural networks (CNN), Stereo IR 170 Camera Module by Leap Motion and other Python libraries with pretrained models.
In the end, I provided a virtual piano software using one of these techniques which is able save output of the piano to a MIDI file.

Summary
This master's thesis is dedicated to monitoring solution design, creation, and testing. The purpose of this work is to create for the Alpha organization a monitoring solution that would allow observing the hospital servers from outside of their local network.
We will study the whole process, from extracting data to determining the correctness of the server operation based on them. It means that we will study areas such as data synchronization, security, failure prediction, etc. We will also explore technologies that simplify this process for us. The technologies are separated into two independent solutions: using the Prometheus and using the TICK stack.
The solution, which is the final product of the work, uses the TICK stack and consists of two separate components that communicate with each other. These are the hospital server monitoring part, which extracts data from the hospital environment, and the collection metrics server part, which collects data from the monitoring part and analyzes them for the different hospitals. We also will call them monitoring and collection solutions.
For more complete monitoring of the hospital environment, there are two types of data sent between these components: application data and metrics.
The metrics sending is implemented using the TICK stack, and the application data sent is implemented as two applications on each communication side. Both of them are written in Kotlin using the Spring framework. These components are also tested in detail in the final part of our work.

Summary
Students of the doctoral study program at FIT CTU in Prague must use paper forms whenever they want to perform any administrative action related to their studies. This system, where they complicatedly pass the completed form to other people to complete and then sign, is unnecessarily difficult for them. Therefore, we will try to propose some changes that could improve these processes.
In this work, we will focus on the analysis of current processes related to doctoral studies
at FIT and analyze the way in which the processes are processed internally. Subsequently, we will present the systems that already exist at CTU and could be used for partial digitization of processes in order to reduce the work of the study officer and the students themselves.

Summary
Edge flow is a fundamental concept in 3D modeling, playing a pivotal
role in natural 3D model deformations mostly used in animation. A 3D mesh does not always possess optimized edge flow. Thus, many tools exist to optimize it, among which all are analytically based solutions. This thesis explores a stochastic approach to the optimization problem while attempting to reframe the problem into a reconstruction task. We point out a common issue in regards to Chamfer distance. The limitation of Chamfer distance hinders the quality of shape reconstruction in most of the published researches. We proposed predicting offsets of the mesh points while exploring how to compute the ground truth for these offsets. We discuss several solutions and their limitations while resorting to stochastic computational solutions. We fully implemented the prediction/reconstruction pipeline but failed to train the model to predict point offsets. Despite many attempts to fix the training by changing the architecture, applying deep learning techniques, tuning the optimizer's hyperparameters, or extending the feature vector, the training result remained defective. We concluded that the model was not powerful enough to learn key shape features.

Summary
This work presents the development and testing of an AR application capable of detecting distinct
clothing and placing animations on it. We developed three different modes using our own clothing
designs. We implemented a fast backend with a NoSQL database and fast file retrieval. We have
also tested different machine-learning models, such as clothing segmentation, skin detection,
and body pose estimation. Surpisingly, we have found out that we can significantly improve
the performance of our animation placement by utilizing the models approximate knowledge of
where the spine of the body is located. During the whole process we tested the application with
users for the optimal UI/UX and AR experience.

Summary
This thesis focuses on the Compose Multiplatform framework, designed for creating cross-platform applications. I introduce readers to this framework and describe its differences from the Jetpack Compose framework. I also analyze existing frameworks aimed at developing cross-platform applications, specifically Flutter, React Native, and PWA. In a comparative analysis, I consider the support of basic functionalities, the quality of documentation, and other factors. In the next section, I design the user interface of an application prototype in Figma and implement this prototype in the aforementioned frameworks. These prototypes are then thoroughly tested. I continue by comparing these platforms using quantitative and qualitative metrics, based on, among other things, a sample walkthrough of the application and the handling of common functionalities. In the final chapter, I compare the suitability of the Compose Multiplatform framework with other platforms, assessing the quality of documentation, framework features, library support, and community engagement.

Summary
In this thesis, we create a decision guide to help companies choose the most appropriate approach to migrate to SAP S/4HANA - Greenfield, Brownfield or Hybrid. A decision tree was initially created based on interviews with experts, but proved to be insufficient. Therefore, we created a decision guide in the form of a quiz that allows prioritization of factors such as cost, risk and time, and then supported this format with a web application. The guide helps companies choose the best approach to migration and demonstrates its practical application on fictional companies. This work provides a practical solution for managers in deciding the best approach to migrate to S/4HANA.
