International Russian Smart Industry Conference (SmartIndustryCon)

作者： Igor Sokolov Yuri Stepchenkov Yuri Diachenko Institute of Informatics Problems of FRC “Computer Science and Control” of Russian Academy of Sciences Moscow Russia

The article researches the problem of self-timed (ST) binary counter implementation. ST circuits demonstrate correct operation over a much wider range of supply voltage and ambient temperature, in contrast to synchronous counterparts. The reason for this is hardware redundancy, two-phase operating discipline and mandatory acknowledging of the switch completion of all circuit cells in each phase of circuit operation. As a result, ST circuits operate stably no matter the cell delays. Due to their simpler indication, serial ST counters have less hardware redundancy than combinational ST circuits. However, they require the specific procedure organization to implement ST preset. The article examines the circuitry basis for the ST counter implementation and proposes a schematic preset realization ensuring its self-timing and optimal hardware complexity.

Nowadays, unmanned aerial vehicles (UAV) are considered for a variety of different applications. One of the important ones is automatic collection of sensory data. In this work, we study the use of UAV-based for secure remote monitoring network enabled via LoRaWAN lower-power wide area (LPWA) network. In the considered use-case the UAVs carry sensors collecting data and LoRa modules to transmit collected data to the stationary gateway. The work focuses on congestion control on the gateway. Specifically, we propose a multi-threshold hysteresis-based control mechanism to alleviate system overload by dropping some of the data send by the sensors. The considered system is modeled using the queuing system with multiple thresholds. The work studies time-dependent characteristics of the system: average time the system spends in overload and reduced load states. Our results demonstrate that using hysteresis control allows for the system to accept priority data traffic even under relatively high system load. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

E-Learning has emerged as the most effective way of getting information in a range of sectors in the contemporary age. The utilisation of electronic content to provide education and development is referred to as e-learning. While the broadening internet has a plethora of e-learning tools, knowledge acquisition is not just an aspect that adds to an individual's enrichment. Assessment and evaluation are crucial parts of every learning system. Due to more complex assessments and quicker inspection, multiple choice questions are becoming extremely prevalent in current evaluations. However, establishing a diversified pool of MCQs relevant to a certain subject matter presents a hurdle. Manually creating high-quality MCQ exams is a time-consuming and arduous procedure that demands skill. As a result, research has concentrated on the automated construction of well-structured MCQ-based tests. This paper presents a paradigm using natural language processing based on semantic similarity and dynamic ontology. The proposed QG-SKI model uses LOD Cloud and Wiki Data to generate Ontologies dynamically and Knowledge reservoir is performed. The dataset is analysed using TF-IDF algorithm and the Semantic Similarity and Semantic Dissimilarity are computed using Shannon’s entropy, Jaccard Similarity and Normalised Google Distance. These algorithms are executed for a multitude of degrees and levels to generate a similar of similar instances. The suggested model has a 98.15% accuracy and outperforms previous baseline models by dampening resilience. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Self-timed (ST) digital circuits, which constitute a subclass of asynchronous circuits, have a number of advantages over synchronous and asynchronous counterparts. Due to the two-phase discipline, redundant data encoding and mandatory acknowledging of successful switching completion in each operation phase, ST circuits operate in a wider range of supply voltage and temperature and are more resistant to soft errors. Excessive hardware costs inherent in ST circuits do not play a significant role at the current semiconductor technology development level. However, the lack of qualified developers and automated design tools for ST circuits hamper the wide ST circuits' practical use. The paper considers an approach to the ST circuit design based on the formalized transformation of the original synchronous Verilog-description of a digital circuit into a description of an ST circuit that has all the ST circuit's properties and ensures the ST circuit synthesis with minimal hardware complexity. The most difficult stage of converting a synchronous circuit description into its ST description is sequential unit implementation. It requires taking into account the nuances of the functioning of ST triggers and units based on them. The paper proposes a formalized method for substituting ready-made parameterized templates of typical sequential ST units instead of synchronous counterparts based on extracting the synchronous counterpart's properties and selecting the most suitable ST template.

International Russian Smart Industry Conference (SmartIndustryCon)

Self-timed (ST) circuits have a number of advantages over synchronous counterparts. They utilize natural interaction between digital units based on data availability. Combinational ST circuits use redundant coding of information and a two-phase operating discipline, which makes it possible to detect the successful circuit switching completion in each phase. The combinational ST circuit synthesis has been well studied, formalized, and implemented in several existing computer-aided design systems for asynchronous digital units. It is based on dualizing the logical function system in order to convert single information signals into dual-rail signals with a null or unit spacer and supplementing an additional indication subcircuit that detects the completion of ST circuit switching into the current phase. The synthesis of ST circuits with memory is less amenable to formalization. The paper considers the problem of implementing typical ST units with memory, namely latches and flip-flops. It analyzes ST latch and flip-flop implementation features and their interaction with the combinational environment, which requires dual-rail coding of information signals, and offers effective circuit solutions that ensure the adequacy of their behavior in relation to synchronous counterparts.

With the advancement of wireless networks the data needs of the wireless internet have become so great, and the use of 4G and 5G so ubiquitous, that challenges arise in the availability and distribution of resources. In this paper we examine an application of Machine Learning and subsequently Neural Networks to offer a solution to this problem. The, now more than ever, profound availability of processing power greatly empowers and makes the deployment of these tools easier than ever, even in problems where in the past their application would not be feasible. The use of machine learning techniques to distribute resources in wireless networks is investigated and contrasted to a traditional algorithmic method. Scenarios are also entertained in which such approaches might be applicable. © 2022 IEEE.
