Web application to support voice-based group work

The electronic control units in vehicles communicate with each other using different protocols, forming a complex automotive electronics network. With the increasing connectivity of vehicles to the internet through mobile networks, the vulnerability of these networks has become a growing concern. However, there is currently no widely accepted methodology for assessing vulnerabilities in vehicle electronic systems.

The aim of the thesis is to develop a methodology for vulnerability analysis of networks in vehicles, with the possibility of using the MulVAL attack graph generator application as one of several implementation options.

To address this issue, the student should review existing literature on vulnerability analysis of traditional IP-based networks, which involves identifying all possible attack paths, and apply this approach to the automotive electronics network. The research will involve identifying data sources and collection methods required for vulnerability analysis, generating an attack graph using MulVAL or other suitable applications, and evaluating the results.

Develop a system (consisting of hardware and software components) that is capable of monitoring and configuring a small artificial environment for green household plants. Evaluate the possible communication protocols, devices, and software components, and plan a system where we can monitor the status of the environment (temperature, humidity, soil acidity, etc.) and we can configure how the automatic components (sprinkler, lighting, etc.) work.

After the planning, implement the system in a cloud/IoT environment so that the result of the development can show how these technologies and these hardware components can be used to emphasize sustainability and achieve a reduced carbon footprint for the created artificial environment.

Topic description:

In the case of web application development, security is the key function to be concerned. Authentication can be defined as the process of verifying someone’s identity by using pre-required details.

The user can be identified by the unique knowledge of some information, e.g. the combination of a username and a password. Another type of method is based on the ownership of some unique item, typically a token or a QR code. A special type of identification methods is based on the unique biometric parameters of the human user.

In the recent years, as one of the trending technologies in security systems, facial recognition got very popular. The idea behind facial recognition is that the human face is considered as a unique identity of an individual, therefore, a camera image could be used for authentication.

In this thesis, the current available solutions for user authentication on the web are collected, categorized and evaluated, with special attention to biometric identification. After reviewing the relevant literature and analyzing similar applications, a novel method of user identification is designed, developed and evaluated.

In the past 30 years, robots first conquered factories, then moved on to service applications. While industrial robots are not allowed to closely work together with robots, human-centered robotics is founded on that very close collaboration. Safety therefore is a critical issue for household, healthcare and other service robotics domains.

During the collaboration and co-working with humans, there are numerous safety aspects to consider. Robot manufacturers developed different protocols and methods to ensure high quality task execution. The global standards and unified approaches are yet missing.

Detailed tasks:

• Analysis of critical human-machine co-working scenarios;
• Objective analysis of existing platforms from the safety point of view focusing on service robots in healthcare;
• Developing an assessment and measurement protocol for safety of human-robot collaboration;
• Evaluating the results in the context of international standards

Basic description of the topic:

Industrial robot arms have extremely good repetition accuracy, but their absolute accuracy, which gives you the accuracy with which a given displacement/rotation can be achieved. This depends on the robot model used for the calculation, which is calibrated by the manufacturers and attempts to track deviations from the nominal model and give a mean value for inaccuracies due to elastic deformations and drive chain uncertainties.

This usually causes 5-10x greater inaccuracy than the robot’s repetition accuracy. This can be improved by improving the robot model. Since the early days of robotics, methods have been developed for this, both for the geometric description of the robot and for the additional uncertainty. Without claiming to be exhaustive, one of them is that the model is not designed for the entire workspace, but only for a narrow zone where precise operations are required. Fuzzy interpolation between these zones is also an exciting issue. Also, adding a soft computing layer to the traditional geometric model to describe additional properties can be a tool for calibration.

The question arose during the handling of biological samples, where the situation is complicated by the fact that, in this case, the glass plates are identified based on the installed camera. The goal is to develop the robot model and the calibration process for more accurate grasping.

Knowledge required for the task:

• C++ and MATLAB (or Python) programming knowledge

• Basic knowledge of robot modeling (Denavit-Hartenberg parameters)
• Optimization methods

Detailed tasks:

1.  Getting to know the parameters of the Denavit-Hartenberg model and related newer methods (e.g. Hayati), and the calibration methods based on them;

4. Data collection with the robotic arm;
5. Implementation, testing and optimization of the calibration procedure using the data;
6. Drawing a conclusion, comparing it with the currently used procedure;
7. Evaluation and publication of results.

Nowadays, machine learning provides different ways for automated techniques for advanced IT tasks such as real-time and fast face detection in mobile devices. It could be used to help to monitor patient’s health status in real-time for online or offline monitoring basis. However, these techniques often have some technical problems regarding the fast changing in lighting conditions and/or fast movement during the processing. This topic is to build a trained AI model for face detection in mobile devices and provide a better way of auto-detection of perfect lighting condition to ensure smooth and better detection results regarding the surrounding environment of the user. The full design of the software together with the workflow starting from the state of the art, requirement specification, design, to the implementation and testing should be well-defined.

Mobility patterns play a crucial role in designing efficient public transportation systems in big cities. Taxicab routes serve as the fundamental basis for uncovering these patterns. The student will develop a link prediction to give a traffic prediction in these temporal networks.

The problem is quite similar to this study [1], however, they use the “classic” New York dataset, that works with a zone-based resolution. In this work, the student will go one step forward, and propose, how the original raw GPS data can be processed to provide meaningful networks and how this data can be used for prediction purposes. The graph convolutional network structure is also used in ref. [2]. However, the structure of the applied datasets was significantly different. The previously applied dataset was recorded using sensor stations and the models concentrated on the prediction of future traffic speed. However, in our case, the data is recorded by the GPS of the taxis, hence, the data is not recorded in fixed points, but in a dynamic way, which we need to process to obtain the spatial and temporal characteristics. Moreover, the aim is the prediction of the traffic intensity and not the speed of the vehicles.

This integrated methodology allowed us to gain valuable insights into the travel behaviors and preferences of commuters, providing a foundation for designing efficient and targeted public transportation services. To validate the effectiveness of the approach, the student will apply it to GPS data obtained from a taxicab company in Budapest.

The thesis must contain:

• Review of literature (network science)
• Data processing (temporal network analyses, link prediction)
• Development of a Python-based algorithm
• A detailed description of the algorithms and framework and a demonstration of its application

Electrocardiogram (ECG) is one of the measured human bio-signals which is used widely in hospitals in order to define the heart activity in real-time basis and to have an overall look on the human health status in a non-invasive way. Many wearable devices and/or sensors for daily basis use are developed to provide real-time continuous monitoring for patient’s health status. Digital data collected using these sensors/devices are stored in different data formats or standards. Therefore, it is a real challenge to ensure data interoperability and compatibility. This topic is to build an online service-based solution running on a linux server which helps to interchange ECG data between different data formats or standards and to provide an analysis of the usage of this service. The full design of the software together with the workflow starting from the state of the art, requirement specification, design, to the implementation and testing should be well-defined.

Topic description:

Deep neural network have shown a great performance in finding correlation between input variables and a target label. Nowadays, models based on deep learning are usually applied for classification problems. In the case of supervised learning, the model learns from labeled training examples: if the number of samples are large, classification accuracy will rise. However, there are cases when there is a large number of categories, with relatively few samples. Humans are able to learn from only a few examples, an interesting field of research is to create machine learning based solutions to create a similar solution.

The key idea behind one-shot learning is to have a system, where prior knowledge is used as a basis of training, and new categories, new classes, new knowledge is added to this base knowledge during training.

The goal of this thesis is to review current state-of-the-art machine learning techniques for one-shot learning and adjacent fields (e. g. zero-shot learning), design and develop a solution for a one-shot learning task.

Basic description of the topic:

Mushrooms intended for the fresh market are currently harvested exclusively by hand. As a result, the mushroom industry is highly dependent on human labor. About half of the operating costs of mushroom farms are labor costs, which consist mainly of harvesting costs. Rising wages, stricter consideration of working hours and working conditions also increase the problems of manual labor. For these reasons, there is a great need to automate the harvest. The first step in automation is the detection of individual fungi using machine vision devices, as well as continuous measurement of environmental parameters. Detection refers to the use of a sensing device that can be used to identify mushroom heads that meet the given conditions and to facilitate the harvesting process. The student’s task is to design this system of devices and implement the monitoring system on a small sample model.

The rapid advancement of technology related to Industry 4.0 has brought about a paradigm shift in the way we interact with assets across various domains. This progress has led to the emergence of the concept of a Human Digital Twin (HDT) – a virtual representation of an individual’s cognitive, physiological, psychological, and behavioural characteristics. The HDT has demonstrated potential as a strategic tool for enhancing productivity, safety, and collaboration within the framework of Industry 5.0.

Meanwhile, the growth in the number of automated processes has correspondingly increased the cognitive load on human operators. In response to this challenge, this paper outlines a process for tracking human cognitive load using the galvanic skin response as a physiological marker and proposes a novel method of building a model based on the Human-Asset Administration Shell (HAAS).

The proposed HAAS framework integrates real-time data streams from wearable sensors, user interactions, contextual information, task specifics and environmental condition to deliver a comprehensive understanding of an individual’s cognitive state, physical wellness, and skills set. To validate the effectiveness of the approach, the student will apply it at the Operator 4.0 laboratory.

The thesis must contain:

• Review of literature (Asset Administration Shell, Human Digital Twin)
• Ontology development
• Development of a Python-based framework
• A detailed description of the algorithms and framework and a demonstration of its application

Electrocardiogram (ECG) is an effective way to define the overall human health status using the heart activity of the patients in real-time basis. One of the challenges in this field is to have a real-time monitoring system for ECG signals in order to define normal and abnormal ECG signals. This solution helps to detect deteriorating patients in the intensive care units (ICU) to prevent further serious problems. This topic is to provide a solution for ECG signal processing to detect anomalies in the ECG signals using AI for signal processing. The main idea is to collect different types of ECG leads, teach it for an AI model, and then use it to generate the formal shape of every type and then detect anomalies by comparing the built model with the input data. The full design of the software together with the workflow starting from the state of the art, requirement specification, design, to the implementation and testing should be well-defined.

The purpose of this work is to formulate an agent-based model of the evolution of body size and insulin sensitivity inindividuals exposed to mutual cultural influences regarding food intake and physical activity levels.

Manual medical data collection using data forms is a challenging task especially when dealing with many patients. The main aim of this research is to create and test the next version of the cross-platform application for medical data collection and storage. The application needs to store the data in a specified data format (JSON) in order to enable further data analysis. This research aims to create a cross-platform application which enables users to store their own data and/or their patient’s data. The full design of the software together with the workflow starting from the state of the art, requirement specification, design, to the implementation and testing should be well-defined.

Comparison of machine learning algorithms via development of a music recommendation system

Manipulating (picking, moving, placing) objects is one of the most dominant functionalities of robots used in industry. In order to manipulate objects, the robot first has to grasp them successfully. In case of bulk production, hard-coded grasping poses can be sufficient, but recently the desire for more-and-more flexible robot systems, capable of rapidly adapting to different unknown objects is increasing. Naturally the hand-crafted grasp poses in this kind of applications are not sufficient, so automatic solutions are sought. The majority of the current grasp detection pipelines consider a predicted probability of the success of the grasp to select the best option. However, the easiest way to grasp an object may not be the best choice for all tasks (e.g.: obstructed best-grasp pose, no collision free place pose for given grasp pose, special required movements such as insertion etc.). A grasp predictor that can consider such task (and robot system) constraints might be better suited for an actual robot application. Moveit Task Constructor provides a flexible framework to implement manipulation tasks for robots, and carry out the motion planning for said tasks. The task constraints, environment and robot setup are also easily accessible using the Moveit functionalities.

The goal of the project is to implement a grasp detector in this framework (likely based on PointNetGPD), that also considers task constraints and robot setup in rating the grasp candidates.

Detailed tasks:

• Implement a grasp detector in the mentioned framework (likely based on PointNetGPD), that also considers task constraints and robot setup in rating the grasp candidates;
• Implement alternative grasp proposal methods for comparison and potentially help with the development of the new grasp pose detection algorithm.

Basic description of the topic:

Complex mechatronic systems increasingly rely on the measurements of sensors and sensor systems. These are usually asynchronous, with different noise, and sometimes with drift, and can measure certain properties of the system. The function of the filter is to provide an optimal estimate of the state of the system based on a model that describes these properties well, for example, the movement state in the case of the localisation task.

In recent decades, the international community has carried out extremely extensive research on the subject. The diploma work identifies, understands and compares the main directions of these methods based on the movement data of the PlatypOUs mobile robot platform developed at the university offline and comparing the efficiency of the procedures with the currently used program packages.

Knowledge required for the task:

• C++ and MATLAB (or Python) programming knowledge
• Git version tracking system
• Control control theory knowledge (state space model, simulation, filtering)
• Knowledge of stochastic calculations (expected value, standard deviation)

Detailed tasks:

1. Learning the basics of linear/extended/unscented Kalman filter methods;
2. Processing the related literature, the selection of the methods to be compared;

Analysis of large medical data sets is a very challenging task due to the amount of data. The used data could be collected using different types of sensors; therefore, it has different data units and different data types. The main aim of this research is to define and implement a workflow for medical data analysis using statistical tools such as R and it’s official libraries. The tool could be used in an offline basis to analyze stored data or in a real-time basis to analyze the medical data in a synchronous way. The full design of the tool together with the workflow starting from the state of the art, requirement specification, design, to the implementation and testing should be well-defined.

Technology now makes available Continuous Glucose Monitors, able to record glycemia for patients at risk in an essentially continuous way over many days or weeks. This single-variable, somewhat erratic signal carries information on the compensation state of the subject wearing the sensor, and might allow the assessment of the efficacy of the lifestyle or therapeutic regimen. However, in order to analyse this signal, advanced mathematical modelling techniques appear necessary, possibly including fractional stochastic differential equations.
