This paper investigates the effect of the change in matrix dimensionality and the relationship between function communication time and execution time, as well as the relationship between memory parameters and execution time, on the efficiency and economic cost of computation when using a serverless platform for high-dimensional matrix data. AWS Lambda was used to create the functions, AWS S3 to store the data, perform the high-dimensional matrix fork multiplication and matrix convolution operations, respectively, and S3 to design the monitoring and data analysis interface, and finally, analyze the statistical data. According to the analysis, the average communication time consumption ratio decreases gradually as the number of matrix dimensions increases. The computation time decreases by increasing the number of nodes as far as concurrency allows. As the memory parameter increases, the computation time decreases, and the total cost decreases and then increases. The experimental results show that the impact of communication costs on serverless computing decreases as the size of the data increases. When the concurrency limit is not reached, there is a significant increase in computational efficiency, reducing the time consumed by individual nodes and the overall computing process. Increased memory improves computational efficiency but does not necessarily result in total cost savings. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Cloud computing is a service level computing that provide various service to the customers in order to establish an effective customer Relationship management (CRM). This offers various services like virtual machine, self-service provisioning, elasticity computing and storage (pay-as-you-go). Cloud computing provides shared services by enhancing resource management scalability, interoperability and prediction resources as a key to realize the resource utilization with high-performance management metrics. However, when the number of users increase, the process of task scheduling and service allocation using a traditional computing environment will degrade the CRM. In order to address this challenge, this research study proposes an Optimal Service Level Scheduling (OSLS) based task allocation design for improving CRM in cloud computing environment. The Adaptive Service Level Scheduling Algorithm (ASLSA) and the Support Level Load Balancer (SLLB) will reduce the workload in cloud computing environment in order to improve the Quality of Service (QoS) of CRM. This process will optimize the resource utilization in cloud platform based on the service requirement. It provides optimal scheduling features to CRM in order to improve the service optimality based on task and enhance the computational processes such as service load management, heterogeneous service delivery, pricing, resource pools and elasticity. The proposed system leverages high performance when compared to the existing models. © 2022 IEEE.

The intensive flow of personal data associated with the trend of computerizing aspects of people’s diversity in their daily lives is associated with issues concerning not only people protection and their trust in new technologies, but also bias in the analysis of data and problems in their management and reuse. Faced with a complex problem, the strategies adopted, including technologies and services, often focus on individual aspects, which are difficult to integrate into a broader framework, which can be of effective support for researchers and developers. Therefore, we argue for the development of an end-to-end research infrastructure (RI) that enables trustworthy diversity-aware data within a citizen science community. © 2022 Copyright for this paper by its authors.

EarLock: Personal Authentication System for Hearables Using Sound Leakage Signals

引用

IEEE Transactions on Mobile Computing 2025年第7期24卷 6183-6196页

Earphone-type wearable devices, also known as "hearables,"will have many functions in the future. Some of those functions will require authentication of the wearer for access to the user's privacy information or settlement of payments. In this study, we propose a new personal authentication system for hearables called EarLock. EarLock authenticates the wearer by acquiring and analyzing ear canal and auricle shape information using sound leakage from the device. The system can be implemented using a speaker and external microphone that are highly compatible with hearables. We implemented three prototype devices and investigated EarLock's authentication performance under various practical scenarios, including walking conditions, noisy environments, and situations with object interference. Experimental results showed that the in-ear, open-ear, and bone-conduction devices achieved balanced accuracy (BAC) scores of 87.2-93.7%, 83.4-94.7%, and 85.9-90.0%. © 2025 IEEE.

In mountainous landscapes, integrating topograph2 ical information is crucial for effective analysis and under3 standing. Remote sensing becomes indispensable in studying mountains, enabling the monitoring of critical aspects such as grassland degradation, snow depth, glacier dynamics. The intricate nature of mountain ecosystems requires a thorough un7 derstanding of their dynamics, given their vital role in providing habitats for unique species, influencing hydrology patterns, and indicating the impact of climate change. However, the persistent challenge of cloud cover obstructs surface observations, limiting the effectiveness of optical sensors. To overcome this obstacle, various cloud removal techniques have been developed, although they tend to struggle in such landscapes. In this study, we introduce CRT-UNet, a UNet-based cloud removal model that incorporates topographical information from Digital Elevation Model (DEM) data as input to enhance perfor17 mance in mountainous regions. By integrating Synthetic Aperture Radar Sentinel-1 (S1) data, DEM information, and topographic insights into Sentinel-2 (S2) data, our model aims to enhance cloud removal capabilities, particularly in challenging terrains characterized by thick cloud coverage and significant elevation variations. This integration of topographical information enriches the cloud removal process, enabling more accurate restoration of obscured terrain features. The results demonstrate the superior performance of CRT-UNet in cloud removal across varying cloud cover levels and complex terrain features, such as rugged peaks and deep valleys. The proposed model outperforms state-of28 the-art cloud removal models quantitatively and qualitatively. This underscores the importance of incorporating topographi30 cal information in remote sensing applications, particularly in mountainous regions to improve data accuracy. © 2008-2012 IEEE.

International Russian Automation Conference (RusAutoCon)

作者： Georgi Martinov Evgeny Salamatin Department of Computer-Architecture Control Systems Moscow State University of Technology "STANKIN" Moscow Russia

The problem of synchronizing parallel tasks in control systems at the level of the part program is reviewed. A general solution, based on a high-level part programming language extension, is proposed for synchronizing parallel tasks within one control system as well as tasks performed by several different control systems. A scheme for synchronizing the CNC with external autonomous devices through the Common PLC Memory, to which the part program, the PLC program and the inputs and outputs (I/Os) of electric automation have access, has been developed. A set of functions in a high-level part programming language, providing zeroing a certain number of bytes, writing bit, byte, long and float data types to the Common PLC Memory and reading them from it, has been implemented. As a part of practical research, a test stand on the basis of the AxiOMA Control CNC system, that controls actuators via the EtherCAT protocol, was assembled; master and slave part programs were implemented; tests, confirming the operability of the mechanism for synchronizing CNC system with external devices by using a part program, were carried out.

International Russian Smart Industry Conference (SmartIndustryCon)

作者： Georgi Martinov Natalia Martemianova Department of Computer-Architecture Control Systems Moscow State University of Technology "STANKIN" Moscow Russia

The paper considers the problems of manufacturing prototypes of printed circuit boards on bench-type milling machines that require the prompt production of a small batch and correction, if it’s necessary. We used modern tools from third-party manufacturers for the preparation of production and processing of single- and double-layer printed circuit boards on bench-type CNC machines. A technique is proposed that formalizes the process of preparing and verifying part programs and manufacturing printed circuit boards. The methodology was tested and an example of manufacturing a prototype of a printed circuit board for a voltage regulator on a machine with an "AxiOMA Control" CNC system was illustrated.
