Special Issue on Compressive Optical Image Encryption
Submission Date: 2022-01-20

Special Issue Website: https://www.mdpi.com/journal/electronics/special_issues/Optical_Image_Encryption Dear Colleagues, New data-processing network systems and new image processing tools have considerably increased the volume of transmitted information. Thus, more complex networks and long processing time become necessary. High image quality and transmission speed are requested for an increasing number of applications. To satisfy these two requests, several either numerical or optical solutions have been offered separately. This Special Issue explores both alternatives and gives particular consideration to research works on the nature to converge towards optical/numerical hybrid solutions for high-volume signal and image processing and transmission. Without being limited to hybrid approaches, the latter are particularly investigated in this Special Issue with the purpose of combining the advantages of both techniques. Pure numerical or optical solutions are also considered since they emphasize the advantages of one of the two approaches separately. This Special Issue will gather a series of articles dealing with compressive optical image encryption. These topics highlight the importance of studying complex data treatment systems and intensive calculations designed for high-dimensional imaging and metrology for which high image quality and high transmission speed become critical issues in a number of technological applications. A second purpose is to highlight the important role of optics in actual information processing systems. The session topics include but are not limited to the following areas: Optical/digital cryptography; Optical/digital watermarking; Optical/digital biometrics; Compressive image; Compressive sensing for images; Compressive optical image encryption; Image compression for the medical image processing domain; Optical cryptanalysis; Novel devices and systems for optical information security; Face/fingerprint/iris/person recognition, person tracking, 3D object recognition; Liveness detection for face recognition; Holography, phase imaging, and their applications; Integral imaging; Devices and systems for 3D imaging and display; Polarization imaging, hyperspectral imaging; Remote sensing: aerial and satellite image interpretations; Industrial applications (e.g., product inspection/sorting).

Special Issue on Design and Theoretical Study of New Antennas
Submission Date: 2022-01-31

Dear Colleagues, The emergence of nanotechnology is promising to revolutionise the semiconductor industry, offering a still greater reduction in the size of electronic components with better performance and lower energy consumption. Future mobile phones, personal computers, and other portable electronic devices will enjoy progressively greater size reduction and superior computational performance, but these improvements will be compromised by the existing antenna technology, that is, using conventional high-permittivity substrates, since miniaturisation of the antenna will result in degradation of both its bandwidth and efficiency. More exotic materials such as low-loss, high-epsilon ceramics may permit size reduction without much efficiency loss, but this still incurs reduction of bandwidth, and such materials are costly. The primary aim of this Special Issue is to seek high-quality submissions that highlight recent breakthroughs in the development of design and theoretical Study of new antennas for future electronic transceivers. The topics of interest include but are not limited to: New materials for antennas and millimetre-wave systems; Wideband antennas; Antenna arrays; MIMO and smart antennas; Active and integrated antennas; Adaptive and reconfigurable antennas; Antennas/antenna arrays for energy harvesting and scavenging; Antennas/antenna arrays measurement; Advanced RF materials, meta-materials, metasurfaces and EBG; Antennas/antenna arrays for 5G communications and the Internet of Things. https://www.mdpi.com/journal/electronics/special_issues/new_antennas Dr. Chan H.

Special Issue on Advances in Low-Frequency Noise Measurements
Submission Date: 2022-01-31

Dear Colleagues, Low-frequency noise measurements are widely recognized as one of the most sensitive tools for the investigation of the quality and reliability of electron devices and systems. The fluctuations that are recorded at the ends of a biased device carry information about the interaction of the charge carriers with the detailed microstructure of the device, and important information about conduction mechanisms in new devices can be obtained from measuring noise. Moreover, it has been suggested that the observation of the noise generated in sensing devices can be used to increase the sensitivity and selectivity of sensors. Notwithstanding the huge amount of scientific literature on the subject, the fundamental mechanisms leading to the generation of low-frequency noise are not fully understood, even in mature devices. With the continuous introduction of new active materials and new advanced devices, being able to measure, characterize, and, possibly, identify the main factors affecting noise in a given technology is of paramount importance. On the one hand, investigating low-frequency noise can provide clues for a deeper understanding of the conduction mechanism in exotic materials and devices; on the other hand, understanding noise origin is a key factor for introducing process changes aimed at increasing the signal-to-noise ratio in emerging technologies. This Special Issue focuses on the latest advances in the field of low-frequency noise measurements, with a particular focus on experimental results relating to new and advanced electron devices, applications in the field of quality and reliability, measurement methodologies, and dedicated instrumentation. Topics of interest include, but are not limited to, the following: Low-frequency noise in electron devices and circuits; Low-frequency noise in advanced materials; Low-frequency noise in optical devices; Low-frequency noise measurement methodologies and instrumentation; Application of low-frequency noise to the evaluation of the quality and reliability of electron devices and systems; Low-frequency noise simulation and modeling. https://www.mdpi.com/journal/electronics/special_issues/noise_measurements Prof. Carmine Ciofi Guest Editor

Special Issue on Millimeter-Wave-Integrated CMOS Radars and Communication Systems: Architecture and Circuit Designs
Submission Date: 2022-01-31

Special issue website: https://www.mdpi.com/journal/electronics/special_issues/Millimeter_Wave_Integrated_CMOS_Radars Dear Colleagues, In the 2000s, radar systems became available as standard equipment even for lower cost vehicles, thanks to the diversification of radar-based applications, which now include automatic emergency braking systems, adaptive cruise control, blind spot detection, intelligent parking assistance, forward collision warning, etc. Most modern commercial radars host their key functions in two chips: a microcontroller and a SiGe BiCMOS chip which drives the TX and RX antennas, and integrates all the RF functions, the ADC/DAC conversions, and the basic baseband functions. The Holy Grail for next generation automotive radars is the implementation of a system‑on‑chip (SoC) sensor in CMOS technology. Despite the great amount of research produced in the last ten years, most CMOS radar implementations are targeted only to short/medium range applications and are very far from proposing actual solutions for a long-range radar sensor. Technical problems are still present and mm-wave designers from academia and industry are working on these. This bottleneck is still represented by the implementation of a high-performance mm‑wave radio front-end. Research efforts are now being made to integrate all the sensors into CMOS technology, which will provide higher data processing capacity in the digital domain, lower power consumption, and costs. Since nanoscale CMOS is also able to cope with communication applications up to the mm-wave spectrum (e.g., 5G), this poses CMOS as the dominant process over BiCMOS in the next future. This Special Issue will host the latest results in the field of integrated mm-wave CMOS ICs for radar and communication, with a focus on circuit design, architectures, component modelling, electromagnetic (EM) simulation, SoC integration, advanced package-to-chip co‑design, and antenna-to-chip co-design. The topics of interest include, but are not limited to: Mm-wave CMOS front-end circuits (LNAs, mixers, VGAs, T/R switches, amplifiers, filters, demodulators) CMOS Oscillators and frequency synthesizers (VCOs, frequency dividers, multipliers, PLLs, charge pumps) CMOS transmitters and power amplifiers for mm-wave applications Integrated radar sensors mm-wave communication circuits and systems-on-chip Prof. Dr. Egidio Ragonese Dr. Angelo Scuderi Guest Editors

Special Issue on Recent Advances in the IoT and Smart City Based on Artificial Intelligence
Submission Date: 2022-02-28

Special Issue Website link: https://www.mdpi.com/journal/electronics/special_issues/IoT_Smart_City_AI Dear Colleagues, The technology of IoT and smart city systems is based on sensors through which an enormous amount of data is collected. Given the inhomogeneity of data coming from different sources and different devices, it is difficult to determine the right methods for their collection, processing, and analysis. The IoT and smart city can be supported by Artificial Intelligence (AI) methods to create devices that simulate intelligent behavior and enable decision making with little or no human intervention. The main role in guiding decision making and autonomous action is played by data analysis, which refers to the extraction of patterns and inferences from collected data through the use of statistical methods and deep learning. Studying and analyzing current information can be used to make better decisions in the future and drive intelligent actions depending on the decisions made. When talking about data analysis, it is important to mention text mining, because many of the data analyzed are in text form. In smart city, IoT devices are interconnected and communicate for various tasks. The use of IoT applications is increasing exponentially, generating a large amount of connected data and, hence, the risk of data breaches and information leakage. Artificial Intelligence is used to develop complex algorithms to protect networks and IoT and smart city systems. This Special Issue of Electronics covers research and discussion on applying AI methods to data collected by IoT and smart city devices in various domains, as well as improving the security of IoT and smart city systems. Both original research articles and comprehensive review papers are welcome.

Special Issue on Frequency Selective Surfaces and Printed Antennas
Submission Date: 2022-02-28

Dear Colleagues, Designing user terminal antennas for 5G bands, mainly when the design includes several frequencies, is a must in the antenna research. New smartphone terminals, managing a variety of sub-6 GHz and millimeter wave frequencies, will arise in the market in the next semesters, and the antennas could be a bottleneck if their designs are not perfectly adapted to their application. In parallel, and no less important, many research works focus on the design and construction of frequency selective surfaces. These elements provide control of the radio transparency of building materials, given the possibility of selective obstruction, and even blocking the radio waves propagating across them. This Special Issue will present scholarly papers that address critical issues in the theory, design, manufacturing (use of new materials and manufacturing process), and measurements (such as fast near-field measurements) of both user terminal antennas and frequency selective surfaces at bands assigned to fifth generation networks.

Special Issue on Application of Wireless Sensor Networks in Accredited Monitoring
Submission Date: 2022-02-28

Dear Colleagues, For a while now, there has been a tendency to monitor all kinds of production processes (Industry 4.0), of logistic processes, our physical activity, the evolution of our health, our eating habits, our sleep habits, our energy consumption, etc. Our daily lives are dotted with smart monitoring devices in charge of providing a large amount of data concerning many aspects of our lives and activities. Current technology allows classical monitoring, but also activity and lifestyle monitoring. This allows us to anticipate the appearance of problems or adversities that can be avoided or minimized by making the right decisions well in advance. IoT devices (Internet of Things) make the development of health, sport, and home-care applications easy. Classical monitoring includes issues such as air pollution, the environment, water quality, parking occupancy, traffic monitoring, and many others. In fact, different approaches have emerged, focusing on other, more novel aspects, such as reliability, quality assurance, accreditation of responsibilities, custody assurance, etc. Current WSN monitoring applications are not only in charge of data collection, but also of guaranteeing its integrity, certifying the processes carried out, and guaranteeing full transparent traceability. The integration of monitoring systems with both certification tools and smart contracts is a further step in the evolution of this type of system, where it is not only a question of monitoring the state of a certain process or activity, but of guaranteeing the authenticity and veracity of the information acquired, and of attesting to its veracity and of safeguarding the corresponding evidences. This Special Issue will explore new and visionary applications in wireless sensor network monitoring. Contributions that address but are not restricted to the following topics are welcome: Medical Internet of Things (MIoT) applications: patient monitoring, elderly monitoring, health assistants, e-nurse, smart and assisted self-care, etc. Smart cities monitoring applications: social pattern identification, governance impact monitoring, informational ecosystem discovery and sharing, participatory applications, etc. Mobility monitoring: dynamic proposition of travel routes according to individual user parameters (phobias, phyllia, allergies, etc.), event-driven mobility due to culture, sport or traditional events, monitoring the environment of people with intellectual disabilities, mobility difficulties (Parkinson disease) or reduced mobility in order to facilitate their mobility through active policies. Drone surveillance and monitoring: unmanned systems (US) in cooperation with wireless sensor networks, optimal data collection, inspection, and monitoring of power transmission lines, critical infrastructure monitoring, large area monitoring, collaborative monitoring. Structural health monitoring: damage detection and characterization for engineering structures, monitoring of the changes demonstrated by a material, or certain properties of a structural system. Environmental monitoring: early fire detection, landslide detection, detection and monitoring of floods and river overflows, forest monitoring, etc. Athlete monitoring: fatigue and recovery monitoring in high-performance sport, smart heart rate monitoring for sports, evaluation of people’s movement, etc. Multi-sensor fusion approaches Blockchain-based certification for smart monitoring systems. https://www.mdpi.com/journal/electronics/special_issues/wsn_accredited_monitoring Prof. Dr. José Javier Astrain Prof. Dr. Alberto Córdoba Prof. Dr. Jesus Villadangos Guest Editors

Special Issue on Artificial Intelligence and Intelligent Robots
Submission Date: 2022-02-28

Dear Colleagues, Intelligent robotic systems are increasingly leaving the protected lab environment and are being deployed not only in factories, but also as unmanned mobile agents in the maritime, aerial or ground domains. A second evolution is that these robotic systems are being equipped more and more with artificial intelligence methodologies (using an Internet-of-Things Cloud infrastructure or embedded on the platform), for tasks such as perception, modeling, planning, resource optimization, etc. However, the incorporation of artificial intelligence into the control paradigm of intelligent robotic systems also still faces many challenges, which are often related to the ‘black box’ nature of artificial intelligence approaches. This leads to problems in terms of risk assessment, explainability, trust, certification and even socio-ethical issues. The aim of this Special Issue is to bring together researchers and practitioners in the field of artificial intelligence and intelligent robotic systems. The Special Issue will present key challenges associated with the incorporation of artificial intelligence methodologies inside intelligent robotic systems and will propose methodologies to address such challenges. We invite original contributions, as well as review papers in this area.

Special Issue on Recent Advances in Energy Management and Planning of Microgrids
Submission Date: 2022-03-31

Special Issue Website link: https://www.mdpi.com/journal/electronics/special_issues/Energy_Management_Microgrids_Planning Dear Colleagues, A microgrid can be defined as a self-sufficient and self-contained energy system that serves a specific user (or group of users) such as a university campus, a hospital complex, a business center, or a neighborhood. Microgrids can operate either isolated or connected to the main grid and are usually composed of several different types of renewable-based and fuel-based generation systems, as well as energy storage systems (ESS). The consideration of all these features gives microgrids high flexibility and allows them to provide continuous energy supply with high reliability and efficiency, as well as at low cost. Nevertheless, to accomplish this, the operation of all the available energy resources within the microgrid must be properly planned and coordinated, which is the main task of the microgrid’s energy management system. In the current microgrid control paradigm, the energy management system is embedded in a control architecture that allows to simultaneously manage the slow- and fast-changing dynamics within the microgrid. This control paradigm is known as hierarchical control, which can be deployed using either centralized and/or distributed communication and control architectures based on classical and/or metaheuristics optimization. Recently, with the rapid adoption of the Internet of Things (IoT), a larger amount of operational data is being stored. In this sense, new energy management tools aim to extract patterns and new ways of operating based on this data using tools such as data analytics and machine learning. The main aim of this Special Issue is to seek high-quality submissions that highlight new applications, address recent challenges related to design, implementation, operation, and validation of the energy management and planning of microgrids. The topics of interest include, but are not limited to: Innovative control schemes for microgrids (e.g., non-hierarchical, non-droop control). Energy management of microgrids using centralized and/or distributed approaches. New data-driven and/or Machine Learning-based strategies for energy management of microgrids. Optimal design, planning, and operation strategies of microgrids. New data-driven and/or Machine Learning-based strategies for planning microgrids.

Submission Date: 2022-03-31

Dear Colleagues, Nowadays, multimedia networking applications benefit from the rapid development of encoding techniques for multimedia data sources, effective Quality of Service (QoS) control mechanisms, and Quality of Experience (QoE) criteria for system optimization. Interoperability solutions are also being proposed to integrate wired and wireless heterogeneous networking systems for multimedia communication.

Special Issue on Gallium Nitride HEMTs: Characterization, Modeling and Design Techniques for Microwave and Millimeter-Wave Applications
Submission Date: 2022-04-01

Dear Colleagues, Thirty years after being proposed as a revolutionary technology, gallium nitride-based high electron-mobility transistors are today a well-established reality. Thanks to the superior properties of the material, such as wide bandgap and high electron mobility, HEMTs have been fabricated with a record performance as to breakdown voltages, current densities, and thermal resistances. On this basis, GaN HEMTs are increasingly attractive in analog front-end circuits capable of delivering, handling, and withstanding remarkable power levels, i.e., high-power amplifiers, switches, and highly survivable low-noise amplifiers. On top of that, all of these key functions can be integrated on what are becoming known as Single-Chip Front Ends. The applications affected by this paradigm shift range from radar to radio communications, in both the commercial and military spheres, and at frequencies which easily reach the V-band. In addition to the terrestrial and air-borne segments, recent years have also seen the first space qualifications of several GaN HEMT processes both by US and European foundries, which testifies to the full maturity of the underlying technology. The present Special Issue aims at collecting original contributions and reviews reporting the state-of-the-art of gallium nitride HEMT technology, with particular focus on characterization and modeling methods, but also including fabrication and circuit design techniques.

Special Issue on High-Efficiency Power Converters for Electric Vehicles: Battery chargers, Electric Drives, and Control Strategies
Submission Date: 2022-04-01

Dear Colleagues, Power electronic converters are a primary component of modern electrical equipment and applications. They are used to allow an efficient conversion and control of electrical power from source to load. This is particularly important in electric vehicles (EVs) where taking the most advantage of the batteries implies an increment of the range of the car. Therefore, power converters are a key factor in the proper development of EVs. These power converters interconnect many indispensable subsystems such as the batteries, the motor (or motors), and the auxiliary systems. Moreover, they control the power flows between them. For instance, the electric motor of an EV is fed from the batteries system, and the link between them is created through a high voltage DC bus. Therefore, and to begin with, there is a DC/DC power converter between the DC bus and the batteries in order to stabilize it, while between the bus and the motor, an inverter is found. The energy flow is easy to see coming from the batteries and arriving at the motor. However, it is not always like that. During regenerative braking, the energy flows the other way around, from the motor back to the bus. Some system has to absorb that amount of power, and in this case, the batteries are the ones that do the job. In a few words, bidirectional converters are mandatory in EVs. Moreover, they need to be able to switch very fast among different operation modes, handle high currents and voltages, and finally be very efficient. There are also more subsystems inside the vehicle, such as the charger. Usually, the EV is charged by means of an internal charger (on-board charger), but this is not the only way. Batteries can be charged from the outside with an external high (or very high) DC power source. Additionally, there is a trend to connect the EV to the grid and help to correct deviations and punctual problems in the mains (V2G concept). As you can see, there are many topics to work on: Novel topologies of highly efficient power converters; Battery management systems (BMS); Equalization circuits to extend the batteries’ lifetime; Control algorithms for power flows; Communications with the EV to help to develop the V2G concept; Original contributions including experimental validation are expected. This Special Issue has the aim of motivating further research on all these topics in order to help to develop new efficient power and control systems for the EV industry. We can all help to reduce climate change. https://www.mdpi.com/journal/electronics/special_issues/Converters_for_EV Dr. Pablo José Quintana-Barcia Dr. Emilio Lopez Corominas Prof. Dr. Manuel Rico-Secades Guest Editors

Submission Date: 2022-04-01

Dear Colleagues, Due to progress in the development of communication systems, it is now possible to develop low-cost wearable communication systems. Wearable antennas are antennas incorporated into clothing or worn close to the body. Wearable antennas are used for communication, IoT, 5G, and medical applications, which include tracking and navigation, mobile computing, and public health and safety. Examples include smartwatches (with integrated Bluetooth antennas), glasses (such as Google Glass with Wi-Fi and GPS antennas), GoPro action cameras (with Wi-Fi and Bluetooth antennas), and sensors to monitor patient health. Wearable antennas are increasingly common in consumer electronics and for healthcare and medical applications. However, the development of compact, efficient wearable antennas is one of the major challenges in the development of wearable communication and medical systems. Wearable medical sensors can monitor and check on patients. Continuous analysis of measured medical data of a large number of patients may result in a better online low-cost medical treatment. Technologies such as printed compact antennas, metamaterial antennas, fractal antennas, and miniaturization techniques have been developed to create efficient small wearable antennas, and they are the main topic of this Special Issue.

Special Issue on Control Systems Engineering in Autonomous Vehicles: Adaptive, Robust and Fault Tolerant Control
Submission Date: 2022-04-30

Dear Colleagues, Control Systems Engineering is increasingly crucial for the development and ongoing improvement of autonomous vehicles. Land-based, marine and aerial operations are becoming more demanding and complex, requiring more effective and flexible control strategies to enable vehicles to perform tasks autonomously, with higher accuracy, availability, and reliability and to safely operate in uncertain conditions.

Special Issue on Reconfigurable Computing and Real-Time Embedded Systems
Submission Date: 2022-04-30

Special issue link: https://www.mdpi.com/journal/electronics/special_issues/reconfigurable_computing_embedded_systems Dear Colleagues, Modern embedded real-time systems are characterized by an always-increasing demand for processing capabilities to serve computationally intensive workloads. For many tasks, hardware accelerators are an essential means to achieve the required level of performance, as in the case of future-generation workloads due to artificial intelligence. As a result, embedded platforms used in real-time systems are considerably more complex than in the past. For example, many challenges are introduced due to the contention produced by multiple cores and hardware accelerators when accessing the main memory or I/O devices, the scheduling policies implemented by the accelerator itself, and the network-based communication. These challenges call for solutions that allow guaranteeing the timing requirements of real-time applications – both from an analysis perspective, where the increased hardware complexity must be correctly captured to guarantee provably safe response time and latency bounds – and from a practical perspective, where suitable hardware and software mechanisms can be devised to arbitrate contention, allowing to increase the overall system’s predictability and performance. Many application domains share these goals, including cyber-physical systems, IoT devices, future-generation autonomous-driving applications, robotics, Industry 4.0, smart-buildings, edge computing, and more. Particular interest is attributed to emerging hardware accelerators based on the field-programmable gate array (FPGA) technology, especially to those embedded platforms that offer the possibility to dynamically - and partially -reconfigure the FPGA at runtime. Dynamic-partial reconfiguration provides a powerful and flexible way to dynamically deploy multiple accelerators, thus overcoming FPGA area constraints that would possibly not allow allocating all of them statically. Furthermore, FPGA-based accelerators offer the chance to analyze their timing behavior with a clock-level timing precision, thus resulting in a great fit for real-time systems. In this Special Issue, we aim to collect high-quality submissions that include the theoretical, engineering, and application aspects of real-time embedded systems and reconfigurable systems. The Special Issue will focus on (but is not limited to) the following topics: Real-time computing architectures Real-time network protocols Reconfigurable systems Dynamic partial reconfiguration Predictable access to shared memories, I/O devices, and accelerators Real-time virtualization Real-time robotics systems Resource scheduling and allocation in embedded real-time systems Optimization in real-time embedded and reconfigurable systems Hardware acceleration Predictable and efficient parallel applications Energy-and-power-aware allocation and scheduling Spatial and temporal isolation Floorplanning in FPGA Timing predictability for artificial intelligence Worst-case and probabilistic real-time guarantees Prof. Dr. Alessandro Biondi Dr. Daniel Casini Guest Editors

Special Issue on Design Tools and Architectures for Coarse-Grained Reconfigurable Computing
Submission Date: 2022-05-01

Dear Colleagues, Emerging applications are pushing the limits of computing platforms. The scalability of integrated circuit technology has slowed down because of the power wall and the cost wall. Performance is no longer the main metric driving the design of computing platforms, being replaced by energy efficiency and cost. On the other side, emergent applications have a fast-evolving cycle, which reduces the lifecycle of application-specific integrated circuits, increasing their cost. Reconfigurable computing offers good tradeoffs between cost, energy efficiency, and performance, compared to other computing platforms (GPP, GPU, DSP, etc.). Field-programmable gate arrays are the most used reconfigurable devices. Their fine granularity offers a very flexible hardware device but they are difficult to program and high-density FPGAs are expensive. ASICs have a high non-recurring engineering (NRE) cost that is difficult to support with the new emergent applications with a short lifecycle. Coarse-grained reconfigurable architectures (CGRAs) offer performance and energy efficiency close to those of ASICs and a programmability level closer to application software, offering a good trade-off between NRE and device cost. However, CGRAs have not yet been widely adopted because of a lack of mature architectures and programming tools. The objective of this Special Issue is to bring together the latest advances in coarse-grained reconfigurable computing (CGRC), including design tools, architectures, and applications. CGRC topics include, but are not limited to: Coarse-grained reconfigurable architectures; Fine-grained versus coarse-grained computing; Spatial and temporal computation in CGRA; Run-time reconfiguration/adaptation of CGRA; Models of computation for CGRA; Programming tools and compilers for CGRA; Energy-aware compilation for CGRA; Simulation tools for CGRA; CGRA for domain-specific applications (image processing, deep-learning, network processing, etc.); Edge computing and high-performance computing with CGRA. https://www.mdpi.com/journal/electronics/special_issues/Reconfigurable_Computing Prof. Dr. Mário Véstias Prof. Dr. José Teixeira de Sousa Guest Editors

Special Issue on Design and Validation of Advanced Quantum Computing
Submission Date: 2022-06-30

Dear Colleagues, Quantum computation is a rapidly developing field and forward leaps forward have been accomplished during recent years. Quantum calculation is evolving from an emerging topic in science into an established field in science and design. With the expanding size of quantum processors, sub-modules that comprise the processor equipment will become too large to precisely reproduce on an old-style PC. Thus, in the near future each new crude plan and boundary decision will require tedious coordination between planning, manufacturing, and test approval. Here, we can show how we can plan and test the exhibition of cutting-edge quantum equipment by utilizing existing quantum PCs. Zeroing in on superconducting transmon processors at the noticeable equipment stage, we can calculate the static and dynamic properties of individual and coupled transmons. We can show how the energy spectra of transmons can be acquired by variational cross-breed, quantum, old-style calculations that are appropriate for close term loud quantum PCs. Furthermore, single-and two-qubit gate simulations are elucidated by means of Suzuki–Trotter decomposition. The strategies clear a promising way towards planning competitor quantum processors when the requirements for ascertaining sub-module properties surpass the abilities of old-style registering assets. In this SI, editors encourage topics related to hypothetical and fundamental research on the potential and restrictions of quantum innovation, quantum design, and validation, and the investigation of how to accomplish a new advance quantum design. The scope of utilization is suited to the new consolidating innovation; for example, cloud mobile/ubiquitous computing, Internet of Things, big data analytics, artificial intelligence (AI), blockchain, and distributed records innovation.

Submission Date: 2022-09-30

Special Issue link: https://www.mdpi.com/journal/electronics/special_issues/Security_IoT_MLBC Dear Colleagues, The security and privacy of users have become significant concerns due to the involvement of the Internet of Things (IoT) devices in numerous applications. Cyber threats are growing at an explosive pace, making the existing security and privacy measures inadequate. Hence, everyone on the Internet is a potential victim of hackers. Consequently, Machine Learning (ML) algorithms are used to produce accurate outputs from large complex databases. The generated results can be used to predict and detect vulnerabilities in IoT-based systems. Furthermore, Blockchain (BC) techniques are becoming popular in modern IoT applications to solve security and privacy issues. Several studies have been conducted on either ML algorithms or BC techniques. However, these studies target either security or privacy issues using ML algorithms or BC techniques, thus posing a need for a combined survey on recent years' efforts to address both security and privacy issues in vulnerable IoT devices using ML algorithms and BC techniques. In this Special Issue proposal, we have summarized the research areas to focus on and the title related to cutting-edge topics, addressing security and privacy issues using ML algorithms and BC techniques in the IoT domain. The Special Issue emphasizes the operational elements of the IoT using machine learning techniques that facilitate intelligence in security and privacy challenges in the real world and in cyberspace. Additionally, we will invite authors to submit case studies based on categorizing various security and privacy threats reported in the past few years (especially during the COVID-19 pandemic) in the IoT domain, along with original research papers as well as survey papers.

Special Issue on Computer-Aided Design for Integrated Circuits and Systems
Submission Date: 2023-01-31

Dear Colleagues, Currently, we are witnessing a rapid development of semiconductor technology. As a result of the transition from microelectronics to nanoelectronics, new families of VLSI chips have appeared. The modern integrated circuits and systems consist of billions and billions of semiconductor transistors. Now, a single chip is enough to implement very complex digital and mixed digital-analog systems. The stiff competition between the manufacturers of integrated circuits and VLSI systems guarantees that only the best products come to the market. The enormous complexity of modern circuits and systems requires the use of Computer-Aided Design (CAD) tools that automate the different stages of the design flow. Unfortunately, modern CAD tools cannot effectively use all the potential opportunities provided by current integrated circuits. As before, many problems related to the design process still require active human intervention. Therefore, there is an obvious need to improve the theory and practice in circuit design automation in order to provide solutions to these problems.
