Network traffic monitoring becomes, year by year, an increasingly more important branch of network infrastructure maintenance. there exist many dedicated tools for on-line network traffic monitoring that can defend the typical (and known) types of attacks by blocking some parts of the traffic immediately. However, there may occur some yet unknown risks in network traffic whose statistical description should be reflected as slow-in-time changing characteristics. Such non-rapidly changing variable values probably should not be detectable by on-line tools. Still, it is possible to detect these changes withthe data mining method. In the paper the popular anomaly detection methods withthe application of the moving window procedure are presented as one of the approaches for anomaly (outlier) detection in network traffic monitoring. the paper presents results obtained on the real outer traffic data, collected in the Institute.

In the current era of architecture, sustainability and energy efficiency are becoming increasingly important, while at the same time, advanced technological tools and analytical methods are reshaping the design and construction of buildings. Architects must think responsibly and globally, as buildings account for a significant proportion of the world's energy use. As architects, we have a responsibility to create ecologically optimal facilities for the long term. Withthis in mind, we would like to present applications that trace the chronological milestones in the development of energy analysis. this paper provides a detailed overview of the different methods of energy analysis. the methods include software developed specifically for energy analysis, an analysis add-on built into modeling software, and among the more innovative technologies, we have also examined parametric design and methodologies based on artificial intelligence algorithms. We have tried to select these methodologies and software in a diversified way to get a more comprehensive picture of how they work. the main aim of this paper is to compare the conclusions drawn from case studies of our previous energy research and from the studies of these energy software, partly subjectively and partly with an objective perspective that tightens subjectivity. As such, a set of criteria we have defined will guide the structure of this analysis. In this article, we will try to highlight the advantages and disadvantages of each method, and we will also try to consider the importance of 3D model-based analysis.
the article analyzes the existing approaches and software tools for popularizing Internet resources using external ranking factors. As the analysis showed, today there is a lot of software that provides tools for auto...

In this paper, we offer an engaging emotion-based movie recommendation system. With our approach, people may effortlessly convey their feelings through natural language in a search box. Using cutting-edge natural language processing tools, we examine and understand the user’s emotional condition. Its recommendation structures make use of strategies. the first technique is content-based filtering, which generates suggestions based on a variety of criteria, including actors, directors, and movie-related content. the algorithm makes recommendations for films based on an analysis of these features and films that the user has expressed interest in. Using the TF-IDF Vectorizer from the sci-kit-learn module, we apply TF-IDF vectorization to the anticipated genre to improve the precision of genre-based movie recommendations. Withthe help of this vectorization technique, we depict the anticipated genre. We used cosine similarity to recommend 10 movies that match the user’s preferences.

Curriculum moral and civic education is the concrete implementation of the construction of socialist spiritual civilization in the school classroom. It is not only a means of moral and civic moral education, but also a way of thinking to learn new knowledge, and it is the unity of moral education and thinking methods. Taking the course of operating system as an example, this paper introduces popular and vivid moral and civic examples from the need of understanding the course knowledge, and explains the course knowledge from a new perspective. these examples include the methodology of understanding things, and at the same time convey healthy and progressive moral and civic themes such as outlook on life, values, social outlook, ethics and scientific thinking methods. the analysis shows that curriculum moral and civic education is not only an external requirement, but also an internal demand of the curriculum itself.

Many probabilistic inference problems such as stochastic filtering or the computation of rare event probabilities require model analysis under initial and terminal constraints. We propose a solution to this bridging problem for the widely used class of population-structured Markov jump processes. the method is based on a state-space lumping scheme that aggregates states in a grid structure. the resulting approximate bridging distribution is used to iteratively refine relevant and truncate irrelevant parts of the state-space. this way, the algorithm learns a well-justified finite-state projection yielding guaranteed lower bounds for the system behavior under endpoint constraints. We demonstrate the method's applicability to a wide range of problems such as Bayesian inference and the analysis of rare events.

Sentiment analysis is an emerging field that focuses on determining positive and negative sentiments, emotions, and measuring their intensity. One application of sentiment analysis is to provide a clearer picture of the general public's opinion on specific topics, such as events, campaigns, services, or specific news, which may be in the form of articles, posts, brief comments, tweets, or even images. While various sentiment analysistools for English texts have been developed, tools for Arabic text sentiment analysis remain limited and often basic. Not only is a vast amount of content generated online in Arabic, but its strategic importance cannot be overlooked. the aim of this paper is to conduct a hybrid approach to sentiment analysis on Arabic text using the Semeval-2018 Task-1 dataset. the proposed method uses a combination of lexicon-based features, word embedding as well as character embedding as features classified by an ensemble of CNN, DNN, GBT, and bi-LSTM models. Results show a 4% improvement over the Semeval-2018 competition's winner. the knowledge gained from this method has been localized, making it implementable for future applications.

As distributed energy sources become more prevalent, maintaining power grid stability is increasingly challenging. By integrating machine intelligence and communication technologies, traditional power networks could transform into smart grids. through machine learning and artificial intelligence, these smart grids can adeptly respond to unexpected changes in consumer demand, power interruptions, surges in renewable energy production, and other crucial situations. Variations in power generation and loads, along with changes in the power system’s structure, lead to varying shifts in the entire network’s active power. Detecting these fluctuations through manual analysis is laborious, but machine learning can be highly impactful in this regard. this study aims to collect comprehensive data for analyzing grid stability, utilizing machine learning tools to thoroughly examine the data, and adopting a multimodal approach to compare model outcomes for an improved solution strategy. Our analysis reveals an accuracy exceeding 0.97, indicating strong potential for practical application and implications.
