Abstract:

Discussed here is a technique for testing digital devices based on the calculation and control of two or more characteristics of a binary electric signal at a reference point. Signals coming from a healthy and failed digital device that are indistinguishable by the value of one of the characteristics may differ in value of the other characteristic. The combination of test methods can significantly reduce the potential of not detecting the failure of digital device. The technique is aimed at increasing the information content of the healthy state monitoring results and the possibility of localizing failures in digital instruments and devices of power systems.

Abstract:

The increasing prominence of wireless multimedia systems and the need to limit power capability in very-high density VLSI chips have led to rapid and innovative developments in low-power design. Power reduction has emerged as a significant design constraint in VLSI design. The need for wireless multimedia systems leads to much higher power consumption than traditional portable applications. This paper presents possible optimization technique to reduce the energy consumption for wireless multimedia communication systems. Four topics are presented in the wireless communication systems subsection which deal with architectures such as PN acquisition, parallel correlator, matched filter and channel coding. Two topics include the IDCT and motion estimation in multimedia application.These topics consider algorithms and architectures for low power design such as using hybrid architecture in PN acquisition, analyzing the algorithm and optimizing the sample storage in parallel correlator, using complex matched filter that analog operational circuits controlled by digital signals, adopting bit serial arithmetic for the ACS operation in viterbi decoder, using CRC to adaptively terminate the SOVA iteration in turbo decoder, using codesign in RS codec, disabling the processing elements as soon as the distortion values become great than the minimum distortion value in motion estimation, and exploiting the relative occurrence of zero-valued DCT coefficient in IDCT.

Abstract:

AbstractThis article offers a research tool for comparative studies of digital communication systems. It brings together the fields of infrastructure studies, Internet governance, and political economy of the Internet with the tradition of systemic media analysis and argues that existing frameworks are inadequate for capturing regulatory and power structures in a complex digital environment. In the article, we develop a framework for conceptualising and mapping the components of digital communication systems – the DCS framework – and operationalise it for standardised measurements by outlining twelve key indicators that can be analysed using empirical data from a number of existing databases. The framework provides a basis for measuring and comparing digital communication systems across national or regional contexts, and thereby developing new typologies for how to understand structural differences and similarities.

Abstract:

With the focus on organizations, this article describes power in relation to mediated surveillance using Luhmann’s systems theory, poststructuralist theory and theory of media sociography. It aims to sketch out the main issues in contemporary surveillance discourse and illustrate the current situation, as well as discuss surveillance from the perspective of poststructuralist theory in relation to Luhmann’s concepts of trust, risk and especially power. The underlying media sociographical question is which storing-, retrieving-, localisation- and temporal possibilities for communication and surveillance do digital media provide and how the realization of this potential feeds back into organizations’ power structures.

Abstract:

In modern very large scale integrated (VLSI) digital systems, power consumption has become a critical concern of VLSI designers. As size shrinks and density increases in chips, it will be a challenge to design high performance and low-power digital systems. Therefore, VLSI designers are trying to reduce power dissipation in these systems by using power optimization techniques. Different mathematical operations can be found in the architectures of most digital systems. The focus of this paper is division. In comparison to other basic computational operations, division requires more iterations, takes a long time, covers a large area, and consumes more power from the digital system. As a result, the system's design requires high speed and a low-power divider in order to improve its overall performance. This paper focuses on dynamic power dissipation. In order to determine which design consumes the lowest dynamic power, different system designs of digit-recurrence division algorithms, such as restoring division and non-restoring division are suggested. An innovative power-optimization technique, the very hardware descriptions language (VHDL) technique, is utilized to the suggested system designs. The VHDL technique achieved the higher optimization in dynamic power, at 93.66% for non-restoring division with internal-loop iteration, than traditional approaches.

Abstract:

The relevance of this study is justified by the introduction of digital transformers to modern electrical substations and the need to create relevant digital systems for the automatics relay protection. The article discusses the basic principles of automatics relay protection of the digital electrical substations. The authors examine the problems of its implementation with the use of embedded systems based on domestic computing systems of the Elbrus family with the support of a protected mode of program execution. They suggest an architecture of the user program for managing the automatics relay protection system at a digital substation. Based on the architecture of user tasks and the requirements of the industrial standard, the authors form the restrictions imposed on the software and hardware of the computing systems used in embedded systems in the industry. This paper presents some results of the protected mode in real problems of automatics relay protection at digital substations. The study demonstrates the advantage of using protected mode in creating programs that control industrial facilities. The authors consider the effect of protected mode on the performance and fault tolerance of the target system.

Data science-based digital twin models of renewable energy system technologies developed in a real-time data-rich environment help develop better decisions and predictions than those in the present environment. Based on this real-time analysis of countrywide data, digital twin contributes to effective and reduced cost-based power system control at the localised level. Developing digital twin models from the collection of relevant data is an innovative technology. The challenge is how to leverage all the operational data and analyse the use of data from across transmission and distribution networks to help achieve the objectives. This paper presents an overview of the existing applications of digital twins in power systems.

Abstract:

The digital power grid system is used to maintain stability and to provide a continuous supply of electrical energy to consumers in the event of a power outage or other interruption of service. This is due to their ability to respond quickly in the event of an interruption. However, unpredictable failures and cascading accidents occur regularly, resulting in a blackout that can cause significant disruption to modern life. Furthermore, the rotor angle behavior can indicate the overall synchronism and stability of the complete digital power grid system. The digital dynamic nonlinear system operators can profit economically and technically from implementing protection measures that are appropriately designed and implemented. This study has utilized data transitions over digital power grids, connectivity used in digital power grids, power quality, network congestion, and stability issues as independent variables. However, the digital dynamic nonlinear system has been used as the dependent variable. The data was collected using questionnaires, and the data was collected from various digital power grids and solar system users. The collected data was analyzed by using SEM PLS 3. The reliability of the collected data was tested by Cronbach’s alpha and the values above 0.7. The results indicated that there are significant values between the variables.

Abstract:

Power-efficient digital controllers are proposed for wireless retinal prosthetic systems. Power management plays an important role in reducing the power consumption and avoiding malfunctions in implantable medical devices. In the case of implantable devices with only one-way communication, the received power level is uncertain because there is no feedback on the power status. Accordingly, system breakdown due to inefficient power management should be avoided to prevent harm to patients. In this study, digital power controllers were developed for achieving two-way communication. Three controllers—a forward and back telemetry control unit, a power control unit, and a preamble control unit—operated simultaneously to control the class-E amplifier input power, provided command data to stimulators, monitored the power levels of the implanted devices, and generated back telemetry data. For performance verification, we implemented a digital power control system using a field-programmable gate array and then demonstrated it by employing a wireless telemetry system.

Abstract:

Digitalization affects the relation between human agents and technological objects. This paper looks at digital behavior change technologies (BCT) from a deontological perspective. It identifies three moral requirements that are relevant for ethical approaches in the tradition of Kantian deontology: epistemic rationalism, motivational rationalism and deliberational rationalism. It argues that traditional Kantian ethics assumes human ‘subjects’ to be autonomous agents, whereas ‘objects’ are mere passive tools. Digitalization, however, challenges this Cartesian subject-object dualism: digital technologies become more and more autonomous and take on agency. Similarly, human subjects can outsource agency and will-power to technologies. In addition, our intersubjective relations are being more and more shaped by digital technologies. The paper therefore re-examines the three categories ‘subject’, ‘object’ and ‘intersubjectivity’ in light of digital BCTs and suggests deontological guidelines for digital objects, digital subjects and a digitally mediated intersubjectivity, based on a re-examination of the requirements of epistemic, motivational and deliberational rationalism.

Abstract:

With the continuous improvement of the integration and intelligence of ubiquitous power Internet of things system equipment, its cost in life cycle management such as data service, operation monitoring, and safety protection is becoming higher and higher. At the same time, the probability of power grid failure, reduced operation efficiency, and function failure will gradually increase with the development of its scale. Accurately evaluating the metering performance of distribution network digital metering system in the operation of power system and improving its accuracy, stability, and reliability are the key issues for its future use in power trade settlement. In this paper, a digital reconstruction method of power metering production data based on digital twin is proposed. The operation data of power system is collected in real time through the data acquisition module, the operation data is analysed, identified, and predicted, and then the analysis, identification, and prediction results are used to realize the visualization and digitization of operation data. Further, the operation data of the digital metering system are monitored and analysed to verify the effectiveness of the method. The advantages and disadvantages of the design scheme of the digital metering system are obtained by analysing the active power error, which provides the basis of practice and selection for the application of the digital metering system.

Abstract:

Abstract Flip-flops are fundamental building block in designing the digital circuits. They contribute significant amount of power consumption in the digital systems. In the modern era of VLSI design, power consumption has become crucial factor. As the technology is scaled down below 65nm, leakage power contributes significantly to overall power consumption of digital circuits. Since, Flip-flop is a fundamental building block in designing digital systems, reducing the power consumption of Flip-flop is required to achieve low power consumption of digital systems. Recently single-phase clocking technique has been employed in designing FFs to achieve low power consumption. This technique reduces excess loading on the clock signal. In this article performance of recent single-phase clocked FFs is compared with the conventional transmission-gate Flip-flop. Also, drawbacks of these FFs are discussed. For the comparison of performance of single-phase-clocked FFs with conventional transmission-gate FF, all the simulations are performed at 45-nm predictive technology on Tanner EDA tool.
