Phishing is a cyber threat where attackers create deceptive websites or emails to exploit individuals for fraudulent purposes such as providing sensitive information like usernames, passwords, or financial details. Hence, detecting phishing emails is of paramount importance to protect sensitive information, preventing financial losses, protecting against identity theft, and maintaining trust. This study employs machine learning techniques to classify and categorize websites that are used for phishing attacks. To achieve this, we proposed a classification model for the detection of phishing domains based on classification rules. These rules were formulated based on analyzing and distributing them into three classifiers: domain name features, search engine opinion (SEO) information of the domain, and security scans by security vendors. A total of eleven classification rules were formulated which were distributed as follows: six rules for the first classifier, four rules for the second classifier, and one rule for the third classifier. Each classifier feeds its results to the main classifier, which then evaluates the received results based on its rules. Domain names from 222 confirmed phishing URLs were used to test the suggested model. The model demonstrated exceptional performance, achieving an impressive accuracy rate of 99.1% during testing.

Knowledge Cores in large formal contexts

Knowledge computation tasks are often infeasible for large data sets. This is in particular true when deriving knowledge bases in formal concept analysis (FCA). Hence, it is essential to come up with techniques to cope with this problem. Many successful methods are based on random processes to reduce the size of the investigated data set. This, however, makes them hardly interpretable with respect to the discovered knowledge. Other approaches restrict themselves to highly supported subsets and omit rare and interesting patterns. An essentially different approach is used in network science, called k-cores. These are able to reflect rare patterns if they are well connected in the data set. In this work, we study k-cores in the realm of FCA by exploiting the natural correspondence to bi-partite graphs. This structurally motivated approach leads to a comprehensible extraction of knowledge cores from large formal contexts data *** Codes 68T30 03G10 97R40 Copyright © 2020, The Authors.

According to the European Commission’s 2020 progress report, 12 Member States will (very) unlikely achieve their target for Article 7 of the Energy Efficiency Directive EED during the obligation period 2014–2020. Moreover, the national contributions to the 2030 EU target, as reported in the final NECPs, stand short of the existing 32.5 % ambition. The EU Green Deal will promote even more efforts on energy efficiency by 2030. Therefore, most Member States need to tackle untapped energy savings potentials. One of the reasons why some savings remain untapped is the difficulty to calculate, and thereby report, the energy savings, as it is challenging to estimate savings aligned with actual savings achieved, including behavioural impacts. To assist Member States to further intensify efforts in delivering energy efficiency improvements by 2030, the new H2020 project streamSAVE supports Member States in estimating energy savings for a set of priority action types. Given the importance of deemed savings approaches in Member States’ EED reporting, streamSAVE focuses on streamlining bottom-up calculations methodologies of standardized technical actions. This paper presents the status of standardized calculations in Europe, starting from an overview of catalogues and an assessment of differences observed among Member States. These catalogues are mainly designed to monitor the implementation of energy efficiency obligation schemes. Next to that, the status is explained in more detail by a range of sectors and end-uses having limited coverage of standardized savings estimations in the EU. To get a clear view on stakeholder’s needs and priorities, the assessment was complemented by an EU-wide online survey and interviews among public authorities & technical experts (October–November 2020). The paper concludes by describing how the exchange of calculation experiences can further improve the implementation of Article 3 (target setting) and Article 7 (obligation schemes or alternati

Using machine learning in clinical practice poses hard requirements on explainability, reliability, replicability and robustness of these systems. Therefore, developing reliable software for monitoring critically ill patients requires close collaboration between physicians and software engineers. However, these two different disciplines need to find own research perspectives in order to contribute to both the medical and the software engineering domain. In this paper, we address the problem of how to establish a collaboration where software engineering and medicine meets to design robust machine learning systems to be used in patient care. We describe how we designed software systems for monitoring patients under carotid endarterectomy, in particular focusing on the process of knowledge building in the research team. Our results show what to consider when setting up such a collaboration, how it develops over time and what kind of systems can be constructed based on it. We conclude that the main challenge is to find a good research team, where different competences are committed to a common goal. Copyright © 2021, The Authors. All rights reserved.

Objective: Birth asphyxia is a major newborn mortality problem in low-resource countries. International guideline provides treatment recommendations;however, the importance and effect of the different treatments are not fully explored. The available data is collected in Tanzania, during newborn resuscitation, for analysis of the resuscitation activities and the response of the newborn. An important step in the analysis is to create activity timelines of the episodes, where activities include ventilation, suction, stimulation etc. Methods: The available recordings are noisy real-world videos with large variations. We propose a two-step process in order to detect activities possibly overlapping in time. The first step is to detect and track the relevant objects, like bag-mask resuscitator, heart rate sensors etc., and the second step is to use this information to recognize the resuscitation activities. The topic of this paper is the first step, and the object detection and tracking are based on convolutional neural networks followed by post processing. Results: The performance of the object detection during activities were 96.97 % (ventilations), 100 % (attaching/removing heart rate sensor) and 75 % (suction) on a test set of 20 videos. The system also estimate the number of health care providers present with a performance of 71.16 %. Conclusion: The proposed object detection and tracking system provides promising results in noisy newborn resuscitation videos. Significance: This is the first step in a thorough analysis of newborn resuscitation episodes, which could provide important insight about the importance and effect of different newborn resuscitation activities. © 2023, CC BY.

Objective: Birth asphyxia is one of the leading causes of neonatal deaths. A key for survival is performing immediate and continuous quality newborn resuscitation. A dataset of recorded signals during newborn resuscitation, including videos, has been collected in Haydom, Tanzania, and the aim is to analyze the treatment and its effect on the newborn outcome. An important step is to generate timelines of relevant resuscitation activities, including ventilation, stimulation, suction, etc., during the resuscitation episodes. Methods: We propose a two-step deep neural network system, ORAA-net, utilizing low-quality video recordings of resuscitation episodes to do activity recognition during newborn resuscitation. The first step is to detect and track relevant objects using Convolutional Neural Networks (CNN) and post-processing, and the second step is to analyze the proposed activity regions from step 1 to do activity recognition using 3D CNNs. Results: The system recognized the activities newborn uncovered, stimulation, ventilation and suction with a mean precision of 77.67 %, a mean recall of 77,64 %, and a mean accuracy of 92.40 %. Moreover, the accuracy of the estimated number of Health Care Providers (HCPs) present during the resuscitation episodes was 68.32 %. Conclusion: The results indicate that the proposed CNN-based two-step ORAA-net could be used for object detection and activity recognition in noisy low-quality newborn resuscitation videos. Significance: A thorough analysis of the effect the different resuscitation activities have on the newborn outcome could potentially allow us to optimize treatment guidelines, training, debriefing, and local quality improvement in newborn resuscitation. © 2023, CC BY.

Hypersurface, a software defined metasurface (SDM) paradigm constitutes a revolutionary technology aiming at offering programmatic control over all aspects of a propagating wave, altering its direction, power, polarization and phase. In the absence of line of sight (LOS) between a transmitter and a receiver, HSF can provide seamless connectivity via programmatic reflection. However, such an application requires fine tuning of the metasurface reconfiguration parameters, which may not be effective when done in an open loop fashion due to model uncertainties. In this work, we consider a feedback-based formulation of the problem, which involves maximization of the received power and propose the use of Extremum Seeking Control (ESC) for the controller implementation due to fact that it is model-free and adheres to the maximization problem. Extensive simulations indicate that the proposed scheme is successful in guiding the impinging wave to the receiver within reasonable time even in the presence of time varying delays incurred by message propagation. In addition, a discrete time implementation is considered, investigating its limitations as we increase the sampling time while also characterizing the traffic within the controller network.

Big Data processing suffers from several limitations due to its magnitude making it time consuming to implement any kind of analysis such as data mining. Evolutionary Algorithms (EAs) are metaheuristic optimization algorithms inspired by the natural behavior of the population evolution such as Genetic Algorithm, Artificial Bee Colony, Artificial Ant Colony and other swarm intelligence algorithms. EAs have recently been used to overcome Big Data limitations, especially memory consumption and the long execution time. This paper provides an overview of the recent research papers that utilize evolutionary algorithms to deal with the optimization problems related to Big Data mining such as clustering, classification and features' selection. © 2020 IEEE.

This work is focused on the controller chip design/ implementation of serial-parallel-switched-capacitor coupledinductor (SPSCCI) inverter applied to high-gain boost DC-AC conversion. The controlled plant is its power part made up of SPSCCI booster and DC-link inverter to perform a practical DC-AC conversion from 12V to 110VRMS, 60Hz. Here, for achieving this goal, the controller is its control part constructed by sinusoidal pulse-width-modulation (SPWM) compensator plus phase generator, and then is implemented under Cadence full-custom design through pre-layout simulation (PRE-SIM) and post-layout simulation (POST-SIM) on a fabricated chip of integrated circuit: no. D35-105B-E0008, TSMC 0.35μm 2P4M, 1500×1500μm 2 , 5.0V, 2.68mW, max frequency 200kHz. Finally, with the help of this controller chip, a closed-loop prototype circuit of this SPSCCI can be realized and verified experimentally for some test cases of DC-AC to validate the feasibility of this inverter.
