Load balancing methods in networks aim to distribute traffic evenly between nodes to prevent overloading of individual routes and improve overall network performance. For instance, machine learning-based routing allows you to analyze network behavior and predict optimal routes for data transmission, which is especially effective in complex dynamic networks. Another option is Pareto Optimization, which is used to consider multiple criteria, such as minimizing latency and energy consumption, simultaneously. The reliability of networks, especially wireless ones, is becoming an issue that requires solutions that can adapt to constantly changing conditions, creating stable communication systems. The article describes and tests a simulation model of a wireless network in which requests are sent from sources through towers to two different recipients simultaneously along several paths. The use of intermediate switching nodes allows using the AOMDV protocol to build different data transmission routes. The simulation results for various modifications of the model allow us to evaluate the advantages of using multipath routing.

The increasing adoption of Docker containers in modern software development requires effective monitoring and optimization to ensure high performance and efficient resource utilization. This paper provides an overview of the various tools and technologies that leverage artificial intelligence (AI) to automate the monitoring and optimization of Docker containers. The authors explore the capabilities of AI-driven tools such as machine learning-based anomaly detection, predictive analytics, and automated resource management. By examining these tools, the authors highlight their benefits in enhancing container performance, scalability, and availability. Through comparative analysis, the strengths and limitations of each tool and their impact on container management are discussed. The findings underscore the potential of AI to revolutionize container monitoring and optimization, leading to more efficient and robust IT infrastructure.

The research is devoted to the problem of project- specific steep learning curve when designing complex hardware microarchitectures. To address this issue, it is proposed to use custom synthesizable kernels that provide computational model inferred from specific properties of target microarchitectures. Using ActiveCore hardware generation framework, previously developed by the author, inference of such kernel for coprocessors with out-of-order (OoO) execution and register renaming is demonstrated. Hardware generator packaged with this kernel offers behavioral specification of execution pipelines functionality and provides decoupled latency-insensitive interface for execution units, which allows to generate designs both in RTL and HLS form in arbitrary combinations. Experimental OoO FPU coprocessor based on this kernel shows capability for concise, high-level, untimed specification, while having sufficient performance for integration with superscalar OoO CPU designs. © 2021 IEEE.

The Sequence-to-Sequence (Seq2Seq) of neural network (NN) method based on recurrent neural network (RNN) and attention mechanism plays an important role in information extraction and automatic summarization. However, this method can't make full use of the text linguistic feature information, and there is a problem of unregistered words in the generated results, which affects the accuracy and readability of the text summarization. To solve this problem, the text linguistic feature is used to improve the input characteristics, and the copy mechanism is introduced to alleviate the problem of unregistered words in the summarization generation process. On this basis, a new method named Copy-Generator Model (CGM) based on Seq2Seq model is proposed to improve the effect of text summarization. The results of experiments using LCSTS (Large Scale Chinese Short Text Summarization) as the data source show that the proposed method in this paper can effectively improve the accuracy of summarization and can be applied to automatic text summarization. © 2021 IEEE.

The article considers the problem of designing a synthesis method for Coarse-Grained Reconfigurable Array (CGRA) architectures. The author observes several general problems of such architecture and demonstrates how they can be solved using the NITTA project example. NITTA - the CAD for generating and programming CGRA processors for cyclic execution of control or signal/data processing algorithms. Target system work principles from hardware, algorithm, and transport points of view provided. The principles of building a target system imitation model and synthesis method based on interaction with that model in dialog form are described. All ideas were demonstrated on the simple algorithm example. © 2021 IEEE.

Automatic Speech Recognition (ASR) systems are known to perform poorly in recognition of atypical speech, which certainly includes emotional speech. The labor-intensive nature of developing comprehensive speech databases for training purposes has led to the widespread adoption of synthetic speech data generation, utilizing existing natural speech, in numerous research studies. This paper examines the impact of standard data augmentation techniques, including pitch shifting, time stretching and volume adjustment on the accuracy of isolated-word recognizer of emotional speech. The experiments carried out indicate a significant increase in accuracy achieved through a single augmentation based on pitch-shifting for all emotional states.

Many universities today offer special courses or entire master programs for cyber-physical systems (CPS) developers training. A multi-aspect design route of the CPS creation is considered as the methodological vector, which should provide a parallel, balanced, and integrated movement from the task to the product. The most important part is knowledge and skills in computing, aimed at designing computing platforms and CPS application software. However, the ongoing segmentation in computing reduces the interdisciplinary interaction effectiveness. We consider the development of an integral perception of a computing system based on a multi-level and multi-domain representation model and a deep understanding of the fundamental universal mechanisms of its functioning as a way to improve the quality of design and the efficiency of interaction between computer specialists. This can be achieved by the development of microarchitectural descriptions of a computing system and its components, filling the gap between architectural representation and implementation-level documents. These principles should be implemented even during specialists training. The means of creating such models and descriptions, as well as the educational laboratory complex of distance learning, which supports the proposed approach, are demonstrated. © 2021 IEEE.

Security plays an important role in many sectors and industries. Nowadays, scams and illegal movements are spreading around the world. Copyright protection for PDF documentation is one of the focus in digital watermarking. Hence, a study was conducted on the related research of digital watermarking on PDF which is text documentation. This paper shows a review of watermarking techniques, characteristics, and possibility of attacks in text document format. This paper also discusses the comparisons between the existing scheme with different domains. The results can be seen from the dominant approaches in text digital watermarking which are the structural approach and hybrid approach. Based on the experimental phase, attacks are in a few formats such as insertion attack and removal attack. These are frequently used to test the robustness of digital watermarks that are embedded into an object. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.
