More than half of the world population is living in cities. It requires extended infrastructure and various services to support the densely concentrated population, ranging from electric grid, private and public transportation, water supply and sewage sanitation, telecommunication, health care, banking, education, childcare, nursing homes, welfare, law enforcement, and governmental operations. Therefore, cities provide a huge opportunity to become smarter by utilizing the latest computer and information technologies. By smarter, we mean that the city operation will be more efficient, cost less, consumes less energy, more connected, more secure, and more environmentally friendly.


The list of enabling technologies that could be used towards smart cities is large. To name just a few, there are Internet of Things (IoT) and sensing technology, new generations of telecommunication technology such as 5G, cyber-physical systems, cloud and service-orientated computing, smart grid, intelligent transportation systems, unmanned aerial vehicles, autonomous driving, machine learning, artificial intelligence, computer vision, and the blockchain technology. One particular valuable opportunity in smart city research is the integration of multiple enabling technologies, which is a largely unexplored territory.


By using the enabling technologies, a wide variety of smart city applications could be developed. We have already seen smart city consortiums and hubs being created that focus on the cultivating and sharing of innovative applications. For example, Smart Cities Connect Media and Research frequently organize events such as conferences, exhibitions, and competitions. They organized the applications into five categories: (1) community engagement, (2) digital transformation, (3) smart mobility, (4) urban infrastructure, and (5) urban operations.


We envisage that many new interesting scientific and engineering problems will arise when integrating multiple enabling technologies together for smart cities. On the other hand, designing smart city applications would also expose areas in the individual enabling technologies that should be improved. Furthermore, in this proposed special section, we encourage researchers to develop coherency in smart city research. What are the common set of requirements for smart cities? How could the enabling technologies work together seamlessly towards future smart cities? These are very important questions to investigate. An important approach is the development of a robust and comprehensive model for smart cities that would be fundamental to the development of many smart city applications.

    Abstract In recent years, a number of wireless indoor positioning (WIP), such as Bluetooth, Wi-Fi, and Ultra-Wideband (UWB) technologies, are emerging. However, the indoor environment is complex and changeable. Walls, pillars, and even pedestrians may block wireless signals and produce non-line-of-sight (NLOS) deviations, resulting in decreased positioning accuracy and the inability to provide people with real-time continuous indoor positioning. This work proposed a strong tracking particle filter based on the chi-square test (SPFC) for indoor positioning. SPFC can fuse indoor wireless signals and the information of the inertial sensing unit (IMU) in the smartphone and detect More >

    Abstract Water quality analysis is essential to understand the ecological status of aquatic life. Conventional water quality index (WQI) assessment methods are limited to features such as water acidic or basicity (pH), dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand (COD), ammoniacal nitrogen (NH3-N), and suspended solids (SS). These features are often insufficient to represent the water quality of a heavy metal–polluted river. Therefore, this paper aims to explore and analyze novel input features in order to formulate an improved WQI. In this work, prospective insights on the feasibility of alternative water quality input variables… More >

    Abstract Water distribution network (WDN) leakage management has received increased attention in recent years. One of the most successful leakage-control strategies is to divide the network into District Metered Areas (DMAs). As a multi-staged technique, the generation of DMAs is a difficult task in design and implementation (i.e., clustering, sectorization, and performance evaluation). Previous studies on DMAs implementation did not consider the potential use of existing valves in achieving the objective. In this work, a methodology is proposed for detecting clusters and reducing the cost of additional valves and DMA sectorization by considering existing valves as… More >

    Abstract In the smart logistics industry, unmanned forklifts that intelligently identify logistics pallets can improve work efficiency in warehousing and transportation and are better than traditional manual forklifts driven by humans. Therefore, they play a critical role in smart warehousing, and semantics segmentation is an effective method to realize the intelligent identification of logistics pallets. However, most current recognition algorithms are ineffective due to the diverse types of pallets, their complex shapes, frequent blockades in production environments, and changing lighting conditions. This paper proposes a novel multi-feature fusion-guided multiscale bidirectional attention (MFMBA) neural network for logistics… More >

    Meng Da, Huiqin Wang, Ke Wang, Zhan Wang
    CMES-Computer Modeling in Engineering & Sciences, Vol.131, No.1, pp. 513-527, 2022, DOI:10.32604/cmes.2022.019040
    (This article belongs to the Special Issue: Computer Modeling for Smart Cities Applications)
    Abstract The properties of the same pigments in murals are affected by different concentrations and particle diameters, which cause the shape of the spectral reflectance data curve to vary, thus influencing the outcome of matching calculations. This paper proposes a spectral matching classification method of multi-state similar pigments based on feature differences. Fast principal component analysis (FPCA) was used to calculate the eigenvalue variance of pigment spectral reflectance, then applied to the original reflectance values for parameter characterization. We first projected the original spectral reflectance from the spectral space to the characteristic variance space to identify… More >

    Xiaoting Zhang, Weidong Gao, Ruru Pan
    CMES-Computer Modeling in Engineering & Sciences, Vol.130, No.3, pp. 1533-1546, 2022, DOI:10.32604/cmes.2022.018763
    (This article belongs to the Special Issue: Computer Modeling for Smart Cities Applications)
    Abstract Historically, yarn-dyed plaid fabrics (YDPFs) have enjoyed enduring popularity with many rich plaid patterns, but production data are still classified and searched only according to production parameters. The process does not satisfy the visual needs of sample order production, fabric design, and stock management. This study produced an image dataset for YDPFs, collected from 10,661 fabric samples. The authors believe that the dataset will have significant utility in further research into YDPFs. Convolutional neural networks, such as VGG, ResNet, and DenseNet, with different hyperparameter groups, seemed the most promising tools for the study. This paper… More >
