A Comparative Analysis Of Collaborative Filtering Models For Game Recommendation Using Cosine Similarity, SVD, K-Means Clustering And Real-Time Game Insights

This paper presents a study on GameRS, a game recommendation system that employs collaborative filtering techniques, including Cosine Similarity, Singular Value Decomposition (SVD), and K-means. Clustering, in conjunction with real-time game insights facilitated by Groq AI. The system integrates data from the RAWG API to provide game recommendations and dynamically retrieves game details, including genres, platforms, reviews, ratings, release dates, trailers, and gameplay mechanics. Furthermore, it presents a novel User Satisfaction Index for Games (USIG), a metric designed to assess anticipated enjoyment by considering factors such as rating, genre similarity, and platform similarity. Users may pose specific inquiries related to games, to which Groq AI provides succinct and accurate answers. GameRS, developed with Streamlit, manages both the front-end interface and back-end logic, allowing users to access recommendations, game details, trailers, and additional features. Evaluation results indicate that Cosine Similarity surpasses alternative methods regarding recall and hit rate, whereas SVD and K-means provide insights into latent user preferences and clustering behaviors.

Traffic Congestion Measures and Sustainability Evaluation of Urban Street

Traffic congestion become a serious problem that traffic engineers still face. This research explains the sustainable indicators and congestion index for urban streets and their implementation to evaluate the performance measures proceeding toward sustainable roads. Congestion measures in terms of speed reduction and sustainable indicators; mobility (congestion index, travel time, and delay), costs (vehicle operating cost), socio-economic effect (in terms of an estimated factor called User Satisfaction Index (USI), and air pollution (Fuel emissions) are estimated. Link 3 has the highest delay value of approximately (2 minutes) for the evening peak period in the north-south direction due to a large number of vehicles dense traffic and mixed land use of the study area that produce many attraction trips daily. Congestion is distributed more spatially during the morning peak periods, while in evening periods is relatively concentrated on a specific link. The reduction in travel speed due to the congestion effect induced higher vehicle operating costs of an average unit of 2.9 per Km for links 1, 2.6, and 2.4 for links 2 and 3, respectively, at peak time from (8 a.m. to 12 a.m.). Generally, traffic congestion is mainly concentrated on Links 1 and 3 of Palestine’s urban street segments. The overall user satisfaction index (USI) is 2.209 and about 44.18%, meaning user satisfaction is less than 50%. This illustrates that the selected segment of the study area is unsustainable regarding the social and commuter opinions aspect.

An effective energy management system for intensified grid-connected microgrids

The utility's utilization of communication technology and renewable energy sources has paved the path for self-sustaining microgrids (MGs). However, the intermittency of solar and wind energies raises concerns about meeting demand effectively. To ensure optimal performance of distributed MGs, an efficient energy management system (EMS) is crucial to tackle this uncertainty. Historically, MGs have primarily achieved operational cost reduction through optimal functioning. Integrating demand response (DR) into the EMS could further enhance operational efficiency and peak reduction. This research work addresses this challenge by incorporating DR programs into grid-connected MGs' energy management. Stochastic programming is employed to account for the unpredictable solar and wind behaviours. Flexible price elasticity is used to calculate price elasticity coefficients, portraying customer responses effectively. The implemented research work compares the Dragon Fly Algorithm with other heuristic approaches, resulting in a 12.42 % reduction in overall operating costs and the efficacy of the proposed algorithm is shown.. Using the Analytic Hierarchy Process (AHP), the User Satisfaction Index is assessed, revealing that the CPP demand response initiative tops the satisfaction scale with a score of 0.92881.. Moreover, this research offers an exhaustive evaluation of techno-economic markers for each scenario, systematically ranked using the proposed AHP methodology..

FairLight: Fairness-Aware Autonomous Traffic Signal Control With Hierarchical Action Space

Although Reinforcement Learning (RL) approaches are promising in autonomous Traffic Signal Control (TSC), they often suffer from the unfairness problem that causes extremely long waiting time at intersections for partial vehicles. This is mainly because traditional RL methods focus on optimizing the overall traffic performance, while the fairness of individual vehicles is neglected. To address this problem, we propose a novel RL-based method named FairLight for the fair and efficient control of traffic with variable phase duration. Inspired by the concept of User Satisfaction Index (USI) proposed in the transportation field, we introduce a fairness index in the design of key RL elements, which specially considers the travel quality (e.g., fairness). Based on our proposed hierarchical action space method, FairLight can accurately allocate the duration of traffic lights for selected phases. Experimental results obtained from various well-known traffic benchmarks show that, compared with state-of-the-art RL-based TSC methods, FairLight can not only achieve better fairness performance, but also improve the control quality from the perspectives of the average travel time of vehicles and RL convergence speed.

A Methodological Framework Based on a Quantitative Assessment of New Technologies to Boost the Interoperability of Railways Services

Concerning the increase in the number of trips and tourists after the COVID-19 pandemic, TSPs (Transport Service Providers) and transport organizations are trying to improve their operability to answer the needs and expectations of passengers. This paper presents a methodology to assess and evaluate to what extent innovative technologies meet the needs of tourists and TSPs involved in the digital ecosystem for door-to-door trips in Europe, making railways and public transport more attractive and consequently encouraging people to use more intermodal solutions in public transport. In this study, two kinds of quantitative data are used: operational KPIs (Key Performance Indicators) and USI (User Satisfaction Index) surveys. The Effectiveness concept, as a metric of the capacity to meet these needs and expectations by the innovative technology, is calculated by merging both types of quantitative data. The method considers tourists’ socio-demographic profiles, allowing comparisons among TSPs and profiles for a specific technology, and it is extended to figure out correlations among variables through regression and Bayesian Networks analysis. In addition, specific socio-demographic data relevant to the needs and expectations were studied through the ANOVA test. This work belongs to the methodological framework of the IP4MaaS (Innovation Program 4 Mobility as a Service) project, which sets six demo sites on which this assessment method will be applied in a further stage. The concept of Effectiveness is applied in all the above-mentioned demo sites for the final assessment. Some IT innovations such as Location-Based Experience and Journey Planning have shown high Effectiveness. This work could be interesting for TSPs and IT (Information Technology) developers, researchers, policymakers, and organizations in the transport sector.

Application of internet of things-based efficient security solution for industrial

Recent years have seen a rise in demonstrations of the Industrial Internet of Things (IIoT). Creating secure Internet of Things (IIoT) applications has become a major challenge. Because of the constant demand for additional functionality, such as foresight, the number of connected devices in the enterprise facility is continually growing. Certifying a smaller number of signatories provides stronger authentication methods and prohibits trustworthy third parties from being publicly certified among the available encryption instruments. Certain network criteria must be met by the virtual network function (VNFs) used in this arrangement. As a result of this output, the final service may be delivered at the lowest possible cost, including processing time and network delay. According to the results of this study, our solution is better suited to simplifying trust management in IIoT devices. These findings reveal that our proposed confidence model may withstand behavioural shifts in hostile IIoT environments. The experimental results show our proposed method BCEPP has a high computational cost of 95.3%, a low latency ratio of 28.5%, and increased data transmitting rate of 94.1%, enhanced security rate of 98.6%, packet reception ratio of 96.1%, user satisfaction index of 94.5%, probability ratio of 33.8% when compared to other methods.

Research on Multi-Objective Optimization Model of Industrial Microgrid Considering Demand Response Technology and User Satisfaction

In the process of wind power, coal power, and energy storage equipment participating in the operation of industrial microgrids, the stable operation of wind-storage industrial microgrids is guaranteed by considering demand response technology and user satisfaction. This paper firstly sorts out the status quo of microgrid operation optimization, and determines the main requirements for user satisfaction considering three types of load characteristics, demand response technology, power consumption benefit loss, user balance power purchase price and wind power consumption evaluation indicators in the system. Secondly, the operation architecture of the windstorage industrial microgrid is designed, and the multi-objective optimization model of the wind-storage industrial microgrid is established with the comprehensive operating cost and user satisfaction as the target variables, and the corresponding solution method is mentioned. Finally, a typical wind-storage industrial microgrid is selected for simulation analysis, and the results show that, (1) Considering the demand response technology, the comprehensive operating cost of the wind-storage industrial microgrid per day is 5292.63 yuan, the user satisfaction index is 0.953, and the wind power consumption rate reaches 100%. (2) By setting four scenarios, it highlights that the grid-connected operation mode is superior to the off-grid operation mode. Considering the demand response technology, the load curve can be optimized, and the time-of-use electricity price can be fully used to coordinate the operation of each unit, which enhances the wind power consumption capacity. The compromise solution of the system comprehensive operating cost and user satisfaction under the confidence level of 0.95 is obtained, namely (5343.22, 0.94). (3) The frontier curve shows that in the process of model solving, it is impossible to optimize any sub-objective by changing the control variables, which proves that there is a close relationship between the comprehensive operating cost of the system and the confidence level, which can provide effective guidance for the optimal operation of industrial microgrids.
