Special Issue Information

Dear Colleagues,

Symmetry creates balance, and harmony results in design. It plays a key role in electrical engineering and computing. Types of symmetries include reflection symmetry, translation symmetry, rotational symmetry, and glide reflection symmetry. This Special Issue will cover the state of the art of advances in electrical engineering, computing, and symmetry and invites researchers to submit original research papers and review articles related to any electrical engineering and computer engineering discipline in which theoretical or practical issues of symmetry are considered. The topics of interest include (but are not limited to):

Symmetry in electrical engineering (electronics, nanotechnology, communications, circuits, architectures, electromagnetics, etc.);
Symmetry in computing (computer systems, computing architecture, programing language, machine learning, neural networks, artificial intelligence, cybersecurity, etc.);
Symmetry in other interdisciplinary engineering disciplines (mechanical, agricultural, biomedical, graphical modelling, industrial, information, materials, space engineering, control, automation, robotics, etc.);
Symmetry, design, and optimization in engineering applications.

Abstract

In this research, we investigate a resistor capacitor electric circuit that exhibits an exponentially decaying transient response. Due to uncertainty in the precise capacitance value, we treat the capacitance as a continuous uniformly distributed random variable. Using this approach, we derive the desired transient current response of the circuit as a function of the capacitance. Subsequently, we develop a probability model for the response current, expressed in terms of probability density function and cumulative distribution function. The model’s validity and correctness are verified, and it is further utilized for probabilistic analysis of the transient current. We demonstrate the application of the model for determining the probability of the transient current response reaching a specific value. By following the same procedure used to derive the probability model of the transient current, probability distributions for other circuit parameters, such as voltages and currents, can also be obtained. Furthermore, for parameters that are functions of the transient current, the probability model can also be obtained from the already derived probability model. To illustrate this, we derive the probability models of three other parameters in the circuit from the already obtained models. We also present examples to demonstrate the usage of the developed probability models. Full article

Abstract

The Internet of things (IoT) extends the Internet space by allowing smart things to sense and/or interact with the physical environment and communicate with other physical objects (or things) around us. In IoT, sensors, actuators, smart devices, cameras, protocols, and cloud services are used to support many intelligent applications such as environmental monitoring, traffic monitoring, remote monitoring of patients, security surveillance, and smart home automation. To optimize the usage of an IoT network, certain challenges must be addressed such as energy constraints, scalability, reliability, heterogeneity, security, privacy, routing, quality of service (QoS), and congestion. To avoid congestion in IoT, efficient load balancing (LB) is needed for distributing traffic loads among different routes. To this end, this survey presents the IoT architectures and the networking paradigms (i.e., edge–fog–cloud paradigms) adopted in these architectures. Then, it analyzes and compares previous related surveys on LB in the IoT. It reviews and classifies dynamic LB techniques in the IoT for cloud and edge/fog networks. Lastly, it presents some lessons learned and open research issues. Full article
