Efficient Criteria of Quantumness for a Large System of Qubits

In order to model and evaluate large-scale quantum systems, e.g., quantum computer and quantum annealer, it is necessary to quantify the “quantumness” of such systems. In this paper, we discuss the dimensionless combinations of basic parameters of large, partially quantum coherent systems, which could be used to characterize their degree of quantumness. Based on analytical and numerical calculations, we suggest one such number for a system of qubits undergoing adiabatic evolution, i.e., the accessibility index. Applying it to the case of D-Wave One superconducting quantum annealing device, we find that its operation as described falls well within the quantum domain.

Inovasi Instrumen Penilaian Menggunakan Aplikasi Kahoot di Masa Pandemi Covid-19

The assessment using Kahoot is a measuring tool to assess the extent to which the learning process is conveyed to students. Based on the interview result with teachers during the COVID-19 pandemic, teachers still use conventional methods in paper tests (paper). Therefore, an assessment instrument is needed that makes it more accessible for teachers to assess students during the COVID-19 pandemic. With the development of technology in education, the researcher develops instruments using Kahoot on the theme 6-subtheme 1 about temperature and heat for the fifth grade of elementary school. This development research aims to produce products in the form of instrument, suitability, and practicality of assessment instrument using Kahoot on theme 6-subtheme 1 about temperature and heat for the fifth grade of elementary school, to know assessment instrument using Kahoot and practicality. This was development research (R&D) with a 4D model consisting of the Define, Design, Develop, and Disseminate stages. The developed assessment instrument was tested to 6 students for the limited test and 13 students for the comprehensive test in the fifth grade of SD N Long. Techniques of collecting data were interviews, student response questionnaires, and documentation. While the data research instruments used were material expert validation sheets, media expert validation sheets, expert validation sheets, practitioners, and student response questionnaires. The results are in an assessment instrument using Kahoot on theme 6-subtheme 1 about temperature and heat. The validation results on aspects of presentation, feasibility, language, application and graphics get an average of 3.52 with a percentage of 84.12%, including the appropriate category. Student responses to the assessment using Kahoot in the limited trial get a proportion of 73.3% with practical criteria, and in the broad trial, it gets 85.6% with efficient criteria. Therefore, the assessment instrument using Kahoot on theme 6-subtheme one about temperature and is feasible and practical to use in assessments in elementary schools.

Nonlinear small-gain theorems for input-to-state stability of infinite interconnections

We consider infinite heterogeneous networks, consisting of input-to-state stable subsystems of possibly infinite dimension. We show that the network is input-to-state stable, provided that the gain operator satisfies a certain small-gain condition. We show that for finite networks of nonlinear systems this condition is equivalent to the so-called strong small-gain condition of the gain operator (and thus our results extend available results for finite networks), and for infinite networks with a linear gain operator they correspond to the condition that the spectral radius of the gain operator is less than one. We provide efficient criteria for input-to-state stability of infinite networks with linear gains, governed by linear and homogeneous gain operators, respectively.

Distributed Reed-Muller Coded-Cooperative Spatial Modulation

This paper proposes the distributed Reed-Muller coded spatial modulation (DRMC-SM) scheme based on Kronecker product (KP) construction. This special construction enabled an effective distribution of classical Reed-Muller (RM) code along source and relay nodes. The proposed DRMC-SM scheme not only offers robustness in bit error rate (BER) performance but also enhances the spectral efficiency due to additional antenna index transmission inculcated by spatial modulation (SM). The usefulness of KP construction over classical Plotkin (CP) construction in coded-cooperation is analysed with and without incorporating SM. An efficient criteria for selecting the optimum bits is adopted at relay node which eventually results in better weight distribution of mutually constructed (source and relay) RM code under proposed KP construction. The numerical results show that proposed KP construction outperforms CP construction by gain of 1 dB in signal to noise ratio (SNR) at bit error rate (BER) of 7 x 10 -7 . Moreover, the proposed DRMC-SM scheme outperforms its non-cooperative Reed-Muller coded spatial modulation (RMC-SM) scheme as well as distributed turbo coded spatial modulation (DTC-SM) scheme in similar conditions. This prominent gain in SNR is evident due to path diversity, efficient selection of bits at relay node and the joint soft-in-soft-out (SISO) RM decoder deployed at the destination node.

At the moment, complex and unified solutions have not been created, with the intensification of processes and control systems in accordance with integral resource-efficient criteria, which increases the urgency of the task of developing a technological basis for a specialized combined electrotechnological complex for water treatment. The aim of the research is to substantiate the structure and parameters of the combined electrotechnological processes of wastewater treatment in paper and cardboard production. When treating wastewater, electrocoagulation processes were used, characterized by the electrochemical dissolution of metal anodes. Also, during the processing, chemical coagulation was used, which is based on the addition of active coagulants to the wastewater: ammonium, copper, and iron salts. To accelerate the precipitation processes, after coagulation, a biocidal flocculant was used, after which the clarified solution was passed through a diaphragm electrolyzer with an inactive membrane. Also, wastewater was subjected to ozonation for the purpose of additional oxidation of pollutants. To mix the coagulant and effluents, we used an atmospheric air supply. After flotation coagulation, the wastewater was separated by sedimentation and filtered, if necessary, through a polystyrene foam filter. After evaluating the results of experimental wastewater treatment of paper and cardboard production, a combined scheme of an electrotechnological water treatment complex is proposed. Calculation of technical and economic indicators showed that the financial costs of processing glue and dye washes using a combined electrotechnical complex are almost six times less than the services of specialized companies for the disposal of such wastewater. Disposal of untreated aqueous solutions of paper and cardboard production without purification is unacceptable - from the point of view of their possible critical anthropogenic load on the environment in such cases.

Comparison Analysis of MAC Protocols for Wireless Sensor Networks

Wireless sensor networks (WSN) are rapidly emerging as an interesting and challenging area of research in the field of communication engineering. This review work is different from other state-of-the-art literature as the MAC protocols discussed here are applicable both for homogeneous and heterogeneous networks. Performances like energy efficiency, cost optimization, throughput, bandwidth utilization, and scalability of the sensor network depend on MAC protocols, which are application-based. In the study, the authors have surveyed different MAC protocols with different merits and demerits. Based on the study, it is very hard to recommend any particular protocol as a standard for implementation as these are exclusively application dependent. The work can be further extended in terms of hybrid protocols, which may carry the advantages of the respective protocols along with energy-efficient criteria for practical implementation. Further cooperative WSN communication can be used for internet of things (IoT)-based systems, where the node placements and multi-operations concepts are of main concern.
