This paper presents a quantum-assisted index modulation for next-generation IoT wireless networks. The NP-hard selection problem is first formulated by quadratic unconstrained binary optimization (QUBO) consisting of constraints feasible solutions. To minimize the number qubits required quantum circuit, this formulation then simplified dictionary-based approach that partially exploits classical...
In this paper, a new structure of HFTI-qZS-CMI has been proposed. The proposed structure is capable of generating high-voltage for medium to high power applications. By adding a switch, a capacitor and a high-frequency transformer and also eliminating an inductor from each qZS-CMI cell, the HFTI-qZS-CMI structure will be created. Using the high-frequency transformer in the proposed structure, l...
Abstract The problem of common mode voltage in inverters can be considered as a major issue which leads to motor bearing failures. To eliminate these voltages, proposing some methods seems to be necessary. This paper has a comparative study on estimating modulation methods of eliminating common mode voltage. The main idea of these methods is based on generation of reference vector with nearest ...

objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
A new technique of modulation index adjustment for pure wavelength modulation spectroscopy second harmonic signal waveforms recovery is presented. As the modulation index is a key parameter in determining the exact form of the signals generated by the technique of wavelength modulation spectroscopy, the method of modulation index adjustment is applied to recover the second harmonic signal with ...
Abstract This paper proposes a novel modulation scheme called “In Phase and Quadrature-Filter Shape Index Modulation” (IQ-FSIM). It aims to enhance the spectral/energy efficiencies (SE/EE) while generalizing several existing modulations index (IM) domains. In this system, bitstream is divided into three sub-streams. The first mapped using amplitude–phase modulation, other two are separately an ...
