Normalized Difference Vegetation Index (NDVI) is widely-used for the monitoring of agriculture crops. Its interpretation is based on thresholds and the colormaps used for the visualization of NDVI maps are discrete. We propose a fuzzy logic approach for both the visualization and the interpretation of the NDVI maps. The rationale is that the NDVI values of agricultural crops exhibit a certain spread, while the interpretation based on thresholds is prone to a certain degree of incertitude. We define several membership functions for modeling three sub intervals of the NDVI values in the [0, 1] range, useful for the interpretation of the vegetation status for agricultural crops. The three sub intervals are corresponding to three categories of vegetation status: dried-out vegetation, moderately healthy and strongly developed. For a Sentinel-2 time series, we compare the visualization using the crisp logic, the Sentinel-2 color palette, and the color palettes resulting from the proposed membership functions implementing the fuzzy logic. We show that our colormap has a smoother color gradient, which can facilitate a more visually-appealing and interpretable transition of colors. We also show an example of inference for the interpretation of the NDVI values for an operational usage of the proposed fuzzy logic approach. © 2024 IEEE.

A communication over an Internet Protocol (IP) based network fails if an endpoint sends packets that are too big to reach their destination and if the sender is unable to detect that. The node on the path that drops these packets should respond with a Packet Too Big (PTB) message. However, multiple scenarios exist in which the sender will not receive a PTB message. Even if it does, it refrains from using the information in case it suspects that a potential attacker forged the message. In particular, we are not aware of any implementation of the secure transport protocol QUIC (e.g., used by HTTP/3) that processes PTB messages. In this paper, we present a novel parameterizable PTB detection algorithm for reliable transport protocols that does not dep.nd on PTB messages. We further describe how to integrate our algorithm into QUIC, present results from an evaluation using the algorithm within a QUIC simulation model and, based on these results, suggest concrete parameter values. © 2023 IEEE.

Fifth-generation (5G) mobile networks are vulnerable to jamming attacks that may jeopardize valuable applications such as industry automation. In this paper, we propose to analyze radio signals with a dedicated device to detect jamming attacks. We pursue a learning approach, with the detector being a convolutional neural network (CNN) implementing a generalized likelihood ratio test (GLRT). To this end, the CNN is trained as a two-class classifier using two datasets: one of real legitimate signals and another generated artificially so that the resulting classifier implements the GLRT. The artificial dataset is generated mimicking different types of jamming signals. We evaluate the performance of this detector using experimental data obtained from a private 5G network and several jamming signals, showing the technique's effectiveness in detecting the attacks. © 2024, CC BY-NC-ND.

This study examines decision-making in software re-engineering within businesses, focusing on the challenges and considerations involved. Financial constraints, time, and staff efforts are critical factors in these decisions. The study identifies difficulties faced by top-level management with legacy systems, existing systems, underused systems, and packaged software due to user resistance and customer dissatisfaction. The primary goal of the study is to assess the importance of software quality factors, especially from the users' perspective, in making re-engineering decisions. It uses the ISO 9126 Model to analyze quality elements in the case study software, aiming to provide guidance for deciding whether to proceed with re-engineering. The study explores functionality, reliability, usability, efficiency, maintainability, and portability as factors influencing re-engineering decisions, based on the ISO 9126 model. To understand user interactions and program performance, the study used unstructured participant observation in the case study software, highlighting the challenges faced by top management due to user resistance. These findings were further confirmed through face-to-face interviews with software users and dep.rtment employees, offering insights into their perspectives on software quality elements. The results reveal that, despite some flaws, the system has valuable features and capabilities. Most employees express a desire to undergo re-engineering to enhance service quality, align with ISO 9126 standards, and leverage the expertise of competent staff for re-engineering activities. © 2023 IEEE.

We propose a hybrid forecasting model that includes time series segmentation, which is based on the DBScan clustering algorithm, and a penalty spline. Each step of the hybrid model required modification for real-time use. The DBScan density-based algorithm was supplemented with technology for working with noise and transition between clusters. A recurrent penalty spline model has low computational complexity and, accordingly, high forecasting speed inside the hybrid model. The forecast efficiency was assessed by a number of indicators that reflect predictive efficiency and extrapolation accuracy of using synthetic, model and real TS. Accuracy indicators (MSPE, MAPE) are below 4%. In comparison with other widely-spread forecasting methods, the proposed hybrid algorithm ranks among the known algorithms. © 2024 IEEE.

The Internet of things (IoT) is getting more and more intrusive into our lives until the day comes when everything becomes connected to the Internet. Due to the limited resources and heterogeneous Internet of Things (IoT) devices, the traditional means of protection are useless and cannot be used to protect these devices. The most important security risks, their causes and the consequences of their occurrence have been listed, scheduled and categorized. The study concluded that there are real security risks that cannot be ignored, and they need to find innovative solutions to eliminate them or reduce their damage to a minimum. This paper showed the main risks addressed in previews research, and outlined the gaps in this field of technology, also producing a brief summary information about the most important solution to avoid many threats against the IoT field. © 2023 IEEE.

The process of selecting a leader to avoid instability in distributed system network after leader failure is called Leader Election Algorithm (LEA). This process becomes more complicated when it faces intermittent or complete links disconnected. the network becomes a one-way behavior if both lines of communication between two points are disrupted and thus the network becomes very slow, especially in systems where time is a critical issue, and the process of communication between points becomes much slower if the network leader is next to the fault or close to it, so the criteria will be established to ensures that the system leader in the Bidirectional ring communication network is in a place that allows next leader to communicate with all points as quickly as possible, and this will be during the election *** research presents a solution for leader failure problem in bidirectional ring network. This research takes into account the existence of intermittent or disconnection links between nodes. It will produce three algorithms to determine a new leader in the network with maximum network performance. It uses the least probability of time steps and the number of messages needed to elect the new leader in bidirectional ring network with N communicated nodes. so that the system remains able to work and communicate with its best capacity during this problem with the number of message complexity O(N) in the worst case. The third scenario minimizes the value of proper leader ID IDCurrent/IDCurrent-idStepCount', and maximizes the value of proper leader place N - (N - nStepCount). © 2024 IEEE.
