In this work, an empirical model based on a pure relation between charge and flux (aka an ideal memristor) has been proposed to fit the experimental data for ReRAM devices in flux charge domain. The model is able to capture the behavior with a very good accuracy, including also the behavior of the memconductance.

Jointly computing the square root (SQRT) and the inverse square root (ISQRT) of floating-point numbers is common in many algorithms, e.g., in image or time series data processing when computing norms or vector normalization. Existing designs suffer from high latency and inefficient resource utilization due to the separate architectures that carry out these two operations. In this paper, we first propose a non-iterative approximation method for computing SQRT and ISQRT based on the Chebyshev min-max criterion to reduce the latency while meeting the accuracy requirements of various applications; thereafter a shared architecture of these two operations is designed and implemented in FPGA with less logic units. In contrast with other approximation solutions, our method does not need to perform any iterations and the accuracy can be mathematically estimated. A comparison with vendor-provided IP cores for FPGAs revealed that our proposed SQRT/ISQRT floating-point IP core utilizes less resources while reducing the clock-cycle latency by nearly four times.

Over the past few years the complexity of Multi-Processor System on Chip (MPSoC) designs increased drastically. This made product verification very challenging and illusive. In order to cope with design complexity, Universal Verification Methodology (UVM) associated with System Verilog Assertions (SVA) are used extensively to build up robust verification environments revealing design issues. This work introduces a new methodology verifying SoC design blocks in two modes: Stubbing mode, where all blocks serving the Design Under Test (DUT) are implemented as UVM active and passive agents; Physical hardware mode, where all blocks are physically running along with the firmware driver. A complete SoC system contains: processor, controller, and encryption engine is studied while implementing the proposed verification approach. Functionality check and coverage collection are performed through UVM scoreboard and subscriber respectively. The proposed approach provides the capability of verifying both hardware and firmware simultaneously in the simulation phase.

In this paper, we employ a systematic and accurate genetic optimization methodology, which incorporates a fast finite-element solver, in order to derive prototype electromagnetic bandgap structures with the maximum possible bandgap or multiple bandgap operational regions. All simulation results are, also, extracted by means of a commercial computational package, verifying thus the advantages of the technique. Finally, a realistic case as part of a 5G telecommunications scenario is examined, where one of the prototype geometries, so developed, is set as ground plane of a printed λ/2 dipole antenna.

In oil drilling systems, vibrations are one of the main sources of economic losses. In this paper, a non-linear continuous model with time delay for the vertical drilling string is proposed to study the torsional vibrations of the drilling string. The Karnopp friction model is used to simulate the stick-slip phenomenon in the interaction between the ground and the drill. In the following, two different methods for reducing torsional vibrations and controlling the stick-slip phenomenon of the drilling string are investigated. In the first method, the effect of changing the system parameters on reducing the torsional vibrations is investigated. In the second method, the torsional vibrations of the drill string are controlled using the pole placement method. In this way, corresponding to the desired response of the system, with the search of parameters space, the appropriate location of the closed-loop poles of the system is found. With the designed control system, it is observed that the torsional vibrations are absorbed and the stick-slip phenomenon is damped.

Radio Frequency (RF) energy harvesting (EH) is a technique to replenish the source of wireless sensor networks (WSNs). Also, many interdisciplinary fields in the Internet-of-Things (IoT) era use RF-EH, like precision agriculture, biomedical, and robotics. Over the years, various designs have been presented in the literature operating in multi- or wide-band frequencies. Usually, a designed system is optimized using specific goals and optimization parameters to obtain maximization in power conversion efficiency (PCE). In this work, a dual-band RF rectifier system that resonates in the Wi-Fi frequency bands of 2.45 GHz and 5.8 GHz is presented. The proposed system is optimized using four optimization techniques, namely the Gradient algorithm, the Minimax algorithm, the Simulated Annealing, and the Genetic algorithm. A set of comparative results is presented to assess the performance of each technique and to obtain the feasible solution of the proposed design. Numerical results demonstrate that a 42.8% efficiency is achieved, having a 16 dBm input power and a 1.7 kΩ output resistance load.

The memristor is a new and promising electronic memory element and could be a possible replacement for the present CMOS components. Due to its nano size, low energy usage and memory effect, it could be used in neural nets, memory crossbars, reconfigurable analogue and digital devices and other electronic schemes. In this paper, a simple, fast functioning modified metal oxide memristor model is suggested. Its corresponding LTSPICE library model is generated and successfully analyzed in a simple neural network. The model’s behavior is in accordance with the basic fingerprints of the memristor elements. Its proper operation and applicability in memristor-based devices is established.

This paper investigates the issue of chaos-based image encryption. A new one-dimensional piecewise chaotic map based on the z-shaped fuzzy number is proposed and investigated, exhibiting regions of constant chaos and high Lyapunov exponent values. A pseudorandom bit generator based on the novel chaotic map is designed and successfully passes the National Institute of Standards and Technology (NIST) statistical tests. This PRBG is applied to the problem of image encryption, introducing a new image encryption scheme by using row and column permutation, chaotic pixel shuffling, and the exclusive OR operation. To demonstrate the robustness of this image encryption technique, various tests, such as differential attack and correlation, entropy and histogram analysis are performed.

Designing green and sustainable IoT applications makes energy consumption a key optimization goal of software development. Modern low-energy devices should be driven by energy-aware software. A promising solution to assist developers in this direction is provided by energy estimation tools. In this article, a method of designing flexible energy estimators is proposed. The introduced solution calculates the expected consumption of programs running on different devices and architectures by using synthetic datasets, the popular Valgrind and Pin profiling tools and the well-established Lasso regressor. In contrast to relevant studies, the emphasis is not on the construction of the most accurate tool, but on the characterization of the correlation between the various metrics (features) and energy consumption, on the comparison between predicting methods and on the construction of practical and easy-to-develop tools. The proposed approach is evaluated using the Polybench benchmark suite in widely used ARM-based systems, achieving an R2 score of 0.96, which is comparable to state-of-the-art approaches.

This work deals with the optimal planning of low-cost/low-profile passive and static electromagnetic skins (EMSs) allowing to implement Smart Electromagnetic Environments (SEMEs) in large urban areas. Owing to the high complexity/scale of the EM problem at hand, the planning problem is formulated as a global optimization one efficiently solved thanks to a suitably-customized System-by-Design (SbD) methodology relying on Machine Learning (ML) and Evolutionary Algorithms (EAs). An illustrative example is shown to assess the effectiveness of the proposed SEME planning method in a realistic scenario.
