Pozycja Integrating Anomaly Detection for Enhanced Data Protection in Cloud-Based Applications(Wydawnictwo Politechniki Łódzkiej, 2023) Czerkas, Konrad; Drozd, Michał; Duraj, Agnieszka; Lichy, Krzysztof; Lipiński, Piotr; Morawski, Michał; Napieralski, Piotr; Puchała, Dariusz; Kwapisz, Marcin; Warcholiński, Adrian; Karbowańczyk, Michał; Wosiak, PiotrIn this research, anomaly detection techniques and artificial neural networks were employed to address the issue of attacks on cluster computing systems. The study investigated the detection of Distributed Denial of Service (DDoS) and Partition attacks by monitoring metrics such as network latency, data transfer rate, and number of connections. Additionally, outlier detection algorithms, namely Local Outlier Factor (LOF) and COF, as well as ARIMA and SHESD models were tested for anomaly detection. Two types of neural network architectures, multi-layer perceptron (MLP) and recursive LSTM networks, were used to detect attacks by classifying events as “attack” or “no attack”. The study underscores the importance of implementing proactive security measures to protect cluster computing systems from cyber threats.Pozycja AI-driven Ecodriving and ETA Solutions for Truck Transport(Wydawnictwo Politechniki Łódzkiej, 2023) Lipiński, Piotr; Morawski, Michał; Napieralski, Piotr; Nowok, Paweł; Zawiślak, Bartosz; Hojdys, Leszek; Lazar, Marcin; Lazarek, Przemysław; Zając, Norbert; Pizoń, Sylwester; Jakubiec, Rafał; Sienkiewicz, Jacek; Gołąbek, Sebastian; Kabocik, Mateusz; Fedrizzi, Szymon; Kuliga, Michał; Frączkiewicz, Mateusz; Malarz, Mirosław; Puchalski, Jarosław; Danysz, Ewa; Grajcarek, MaciejPozycja Mobilnie aktywni(Wydawnictwo Politechniki Łódzkiej, 2022) Napieralski, PiotrW konkursie programowania aplikacji mobilnych wzięło udział 110 uczestników – studentów informatyki stosowanej oraz Information Technology, w tym studenci wymiany z Portugalii. Zadaniem było stworzenie aplikacji wspomagających rozwój fizyczny.Pozycja Pupil Detection Methods for Eye Tracking(Wydawnictwo Politechniki Łódzkiej, 2018) Rynkiewicz, Filip; Daszuta, Marcin; Napieralski, PiotrThe theory that pupillary changes can reflect human psychophysical character was confirmed in several conducted studies. Authors of those studies have used devices called eye trackers in order to measure pupillary changes, blinking rate, eye movement patterns or even a gaze position. The main goal of those apparatuses is to locate the pupil on a given image using implemented pupil detection algorithms. In this paper the main focus will be set on several states of art pupil detection methods. All represent different approaches to performing the same tasks in difficult situations for ex.: low/high condition, low image resolutions or low contrast.Pozycja Affective Pathfinding in Video Games(Wydawnictwo Politechniki Łódzkiej, 2018) Daszuta, Marcin; Wróbel, Filip; Rynkiewicz, Filip; Szajerman, Dominik; Napieralski, PiotrTo allow player submerge in created environment of a video game, agents called Non-Player Characters (NPCs) should act believably. One of the most vital aspect, in case of NPCs is pathfinding. There are a few methods that allow change path finding algorithms to become more human-like. Yet, those are not considering many vital aspects of human decisions regarding path choosing. The main purpose of this paper is to present known approaches and show example of a new approach that wider considers psychological aspects of decision making in case of choosing a path.Pozycja Markerless assisted rehabilitation system(Wydawnictwo Politechniki Łódzkiej, 2013) Binkowski, Michał; Guzek, Krzysztof; Napieralski, PiotrThe project focuses on the use of modern technology to analyze human movement. This analysis turns out to be useful aid for physicians in rehabilitation of patients with limb injuries. This method is more precise than simple observation of the patient through the organ of sight. The proposed system allows markerless determination of deviations between the selected bones and joints, and as a result do not require specialized and expensive equipment. The implemented application presents instructional animation of the exercises and verify the correctness of its performance in real time. The equipment that meets the requirements of the project is the Microsoft Kinect, which is nowadays widely used in the medical field.Pozycja Interactive visualization of magnetic fields(Wydawnictwo Politechniki Łódzkiej, 2013) Napieralski, Piotr; Guzek, KrzysztofIn this paper, we present an interactive method for visualizing three-dimensional nonlinear, unsteady vector fields. Visualization of three-dimensional electromagnetic fields is a difficult issue because the user has to be able to assess the distribution of the vector in the context of complex geometry. The authors propose a novel scheme to visualize the flow of vectors.
