Special Issue Information

Dear Colleagues,

We would like to invite submissions to a Special Issue of Applied Sciences on new paradigms in smart cities and societies entitled “Advanced Applications of Computer Science and AI in Smart Cities and Societies”. The penetration of data in the world is significantly increasing due to the need to apply different devices and applications to human activities in modern life. In order to effectively manage and control daily activities, such data should be considered appropriately in decision-making procedures to find optimum solutions. To achieve these purposes, computer science is used to help modern society in all aspects of building smart cities. Actually, implementing computer science applications in human societies is at the heart of modern smart cities, in which any disturbance might lead to unsuitable consequences, abnormal situations, security issues, and even disorder and chaos. In order to cope with ever-increasing data, complexity, and security in modern smart cities, new architectures, concepts, algorithms, and procedures are essential. This Special Issue aims to encourage researchers to address the technical issues and research gaps in applying computer science applications in smart cities to improve daily life in human societies. The topics of interest of this Special Issue include, but are not limited to:

  • Smart grids protection and security;
  • Smart grids stability;
  • Data-mining approaches in smart cities;
  • Issues in data analytics;
  • Advanced teaching using computer technologies;
  • Modern banking based on data analysis;
  • Machine learning applications in smart city hospitals;
  • Technical issues in learning algorithms;
  • Advances in optimization methods;
  • Data-mining architecture;
  • Artificial intelligence applications to improve smart city performance;
  • New paradigms for electricity infrastructures in smart cities;
  • Systems concepts;
  • Methodologies and applications of modern methods for image processing and pattern recognition;
  • New trends in communication links and data transfer;
  • Design, modeling, and management of networks;
  • Developing heuristic optimization algorithms;
  • New approaches in managing smart cities based on data analytics approach;
  • Communication issues in smart cities;
  • Monitoring, control, operation, stability, and security in smart cities;
  • Optimization of losses in sensor, electricity, and communication networks;
  • Managing water distribution in smart cities;
  • Modern electrical transportations, electrical vehicles, smart navigations, and map routing in modern smart cities;
  • Data-mining approaches in modern societies;
  • Cloud computing.

There is a great need to implement preventive mechanisms against shootings and terrorist acts in public spaces with a large influx of people. While surveillance cameras have become common, the need for monitoring 24/7 and real-time response requires automatic detection methods. This paper presents a study based on three convolutional neural network (CNN) models applied to the automatic detection of handguns in video surveillance images. It aims to investigate the reduction of false positives by including pose information associated with the way the handguns are held in the images belonging to the training dataset. The results highlighted the best average precision (96.36%) and recall (97.23%) obtained by RetinaNet fine-tuned with the unfrozen ResNet-50 backbone and the best precision (96.23%) and F1 score values (93.36%) obtained by YOLOv3 when it was trained on the dataset including pose information. This last architecture was the only one that showed a consistent improvement—around 2%—when pose information was expressly considered during training. Full article

The complexity of power system networks is increasing continuously due to the addition of high capacity transmission lines. Faults on these lines may deteriorate the power flow pattern in the network. This can be avoided by the use of effective protection schemes. This paper presents an algorithm for detecting and classifying faults on the transmission network. Fault detection is achieved by utilizing the fault index, which depends on a combination of characteristics extracted from the current signal by the application of the Stockwell transform and Wigner distribution function (WDF). Various faults are categorized using the quantity of phases with a faulty nature. The fault events like phase to-ground (L-G), two phases (LL), two phases to-ground (LL-G), and three phases to-ground (LLL-G) are investigated in this study. The performance of the algorithm designed for the protection scheme is tested for the variations in the impedance during the fault event, variations in the angle of the fault incidence, different fault locations, the condition of the power flow in the reverse direction, the availability of noise, and the fault on the hybrid line consisting of two sections of underground cable and the overhead line. The algorithm is also analyzed for discriminating switching incidents from fault cases. A comparative study is used to establish the superiority of the proposed technique as compared to the Wavelet transform (WT) based protection scheme. The performance of the protection technique is established in MATLAB/Simulink software using a test network of the transmission line with two terminals. Full article
