String search algorithms play an important role in many research areas such as data mining and bioinformatics. While there exist a number of algorithms that handles the topic, we are exploring the the Knuth-Morris-Pratt (KMP) and Boyer-Moore algorithms due to their efficiency and versatility. In this work, we compared the algorithms in terms of characteristics, performance and implementation details. We also tested both the algorithms with various patterns and texts that differs in size. We also analyzed the performance of the algorithms on 4 different processors to understand the technological advancements effects on their performance. Our findings suggest that the BM algorithm perform better with large texts and patterns, while the KMP algorithm is better suited for smaller ones. Also, while newer processor generally exhibit improved performance, the significance of these enhancements may vary. Thus, we should rather be looking specific architectural advancements within generations rather than focusing solely on the generational gap. © 2025 IEEE.

A well-designed water distribution system is crucial for maintaining high service standards in any modern smart city. Moreover, as the population is sky-rocketing, the demand for energy and water is increasing more rapidly than a decade before. Therefore, ensuring a steady clean water supply with optimized energy and water consumption has become necessary. To accurately monitor water distribution systems, the accuracy of input data plays a vital role in determining how accurate the system's status estimations are. There must be a way for system operators to know what is going on at any given time to make practical decisions about how reliable the data they are receiving is. The input data uncertainty can induce flow and pressure calculation inaccuracies, which can be fatal while planning for future demands and needs to be *** the degree of uncertainty in predicting the water distribution system's capacity or load can help people better prepare for future capacity or load predictions. Accurate uncertainty calculations are critical to time series forecasting. Probabilistic formulae are widely employed with classical time series models to estimate uncertainty. But incorporating new data and fine-tuning these models is a challenging task. This research paper presents a Bayesian LSTM network that computes both time series prediction and uncertainty assessment at the same time. In this paper, a real-time data set from VCU's OpenCity test bed is employed to evaluate the efficacy of the suggested strategy. © 2022 IEEE.

Sensor-based Human Activity Recognition (HAR) is crucial in ubiquitous computing, analysing behaviours through multi-dimensional observations. Despite research progress, HAR confronts challenges, particularly in data distribution assumptions. Most studies often assume uniform data distributions across datasets, contrasting with the varied nature of practical sensor data in human activities. Addressing data heterogeneity issues can improve performance, reduce computational costs, and aid in developing personalized, adaptive models with less annotated data. This review investigates how machine learning addresses data heterogeneity in HAR, by categorizing data heterogeneity types, applying corresponding suitable machine learning methods, summarizing available datasets, and discussing future challenges. © 2024, CC BY.

The use of telepresence robots in educational settings offers a promising solution for students who are unable to attend classes in person due to illness, disability, or other barriers. However, the extent to which these technologies facilitate the perceived inclusion of remote students remains underexplored. This study investigates the experiences of remote students using telepresence robots to attend university classes, focusing on factors that mediate their sense of inclusion. Through an inductive analysis of interviews and observations from 22 remote students, we identify technological and socio-pedagogical factors that influence inclusion. Our findings reveal that while telepresence robots enhance physical presence and agency compared to traditional video conferencing tools, challenges such as technological limitations, social norms, and pedagogical practices can hinder full integration. We offer recommendations for educators and institutions to better support remote students and suggest design improvements for telepresence technologies to foster inclusivity in classroom settings. © 2025 Copyright held by the owner/author(s).

Our information is constantly under threat when transmitted through public networks. So, research to keep information secret has been carried out. Mainly, steganography, which consists of hiding data in digital media, receives much attention. Existing steganographic systems identified the need to improve performance by reducing a tradeoff between the peak signal-to-noise ratio (PSNR) and bits per pixel (BPP). In this paper, we propose a new steganographic scheme to embed the bits of secret messages in a digital image's pixels. Our method expands the differences between the neighbouring pixels for secret data concealment. We group the pixels in blocks of size 1×3, and two of the three pixels of the block are candidates to hold the secret bit. We also propose extracting the hidden data to validate our data concealment scheme. To extract the secret data, we also arrange the neighbouring pixels into blocks of three and use their differences, and a modulus function, based on pixels identified carrying the secret data based on the key generated during data concealment. To evaluate the performance of our scheme, we consider the PSNR and the BPP as metrics. The experimental results showed better performance over the existing methods with 68.7790 dB for the PSNR and 0.1562 BPP. © 2023 IEEE.

Smart Door Lock System is used to protect priceless and prevent unwanted access to a room. A usability evaluation is required to raise the system's usability level because it will help to decide how acceptable the system is. UMUX, UMUX-Lite, and SUS comparative ratings are used to gauge the usability level. The System Usability Score (SUS) has more questions than the UMUX and UMUX-Lite approaches. The general degree of acceptance of this system was deemed to be acceptable during the system's evaluation period. With an average UMUX score of 68,1, which is in the marginal category, the UMUX-LITe score is 77.3, which is categorized as acceptable, and the SUS comparison score is 73.0, which is categorized as acceptable.

Autonomous induction generators have such advantages as simplicity of design and high reliability. For a number of generators based on general industrial induction motors, their admissible capacities were determined according to the criterion of permissible thermal load of the stator winding. A digital filtering algorithm was developed for discrete adjustment of the capacitance of the excitation system under the conditions of stochastic load, which allows to avoid rattling of contacts at switching points. © 2023 IEEE.

The role of learning media greatly supports the learning process, increasing motivation and interest in the process. Learning media can also be a place to improve competence optimally through bootcamp training menus and the like with more specific training objectives. The main objective of this study is to develop a gamification-based website to enhance students' preparedness for their Final Competency Test by tackling challenges in comprehending programming absent practical experience. The learning method implemented in this website is case-based learning that integrates dynamic coding activities. The research method uses the Plomp approach with 3 main stages, namely preliminary research, prototyping, and assessment stage. The trial of the gamification website began with media and content validation followed by small group testing and large group testing. Validation by media and material experts led to the execution of small group trials (95.7%) and large group trials (91.7%), producing exceptionally positive outcomes. The results of the small group test with 12 respondents produced a very suitable value with a score of 95.7 and the large group test with 27 respondents produced a score of 9 1. 7 % with very suitable criteria. This indicates that the web-based platform is highly viable for assisting vocational students in acquiring software development skills, enhancing their preparedness for practical IT positions such as software developers and system analysts. Subsequent study involved the incorporation of gamification, such as computer-supported collaborative learning. © 2024 IEEE.
