Listed is a summary of the contributions of the papers pertaining to various application domains:
Cybersecurity is an important concern for every organization. In this special issue, twelve papers deal with intrusion detection, integrity, and confidentiality. In [1], the authors describe an intrusion detection system for wireless mesh networks that identifies intrusion activities using a support vector machine classifier. The proposed method employs a hybrid genetic algorithm and a mutual-information technique for feature selection. In [2], a scheme is proposed to provide a secure outsourcing solution for the matrix-chain multiplication problem in cloud computing. For preserving data confidentiality, the client employs few linear transformation schemes. The proposed verification scheme helps to maintain the integrity of the computed result. In [3], the authors evaluate the efficiency of various deep learning methods to detect and classify domain names as either malicious or benign by automatically extracting the required features thus reducing the burden of manual feature engineering approaches. In [4], the effectiveness of recurrent neural network (RNN) and its variant long short-term memory (LSTM) is analyzed for Android malware detection of time-varying sequences of benign and malicious applications. This paper also provides a comparative analysis with other machine-learning classifiers. In [5], the authors propose a data-driven intrusion detection system for Industrial Internet of Things (IIoT) to hybridize both anomaly and specification-based schemes. In [6], an intelligent monitoring technique for smart grid security assessment using interleaved index is proposed. In [7], a dual encryption methodology using an optimal asymmetric encryption and a probabilistic approach is proposed for balancing both security and efficiency of the binding update for IPv6 mobility. In [8], the security of a chaotic system based image encryption algorithm is evaluated to reveal its unknown defects using chosen-plaintext and known-plaintext attacks. In [9], deep learning is employed for detecting malicious URLs. In [10], a scheme is proposed for secure information retrieval in the cloud. In this approach, the keywords extracted from the documents are distributed into different buckets and during the search process each search query is compared with the document indexes within appropriate buckets. In [11], the authors investigate the event data generated by the Domain Name System (DNS) Internet protocol for the purpose of Cyber threat situational awareness. Deep learning has been employed to classify the domain name as either benign or malicious. In [12], the authors present an extended taxonomy of intrusion detection systems and review the state-of-the-art techniques of related data pre-processing.
Biometrics technology is widely used as a security measure for verifying identity and detecting criminals. This special issue includes five papers on biometrics. In [13], speech data have been collected from various scenarios and a speaker identification system is developed. Based on the study, the authors conclude that performance degrades when mismatching occurs in training and testing sensors. In [14], a system level design for Hierarchical Temporal Memory (HTM) that exploits the combination of a memristive crossbar based Spatial Pooler and a conceptual analog Temporal Memory is presented. In [15], the authors propose a secured authentication protocol for remote Internet of Things (IoT)-based services. Another interesting idea is presented in [16] to detect face spoofing attacks by extracting various feature descriptors concatenated and classified by Logistic Regression. In [17], an automatic tongue-print identification method is proposed. The texture patterns are extracted from tongue images using the Local Binary Pattern (LBP) texture representation method.
Natural Language Processing (NLP) is an interdisciplinary area that is mainly applied for improving communication between humans and machines. Four papers in this special issue deal with issues related to NLP. In [18], a novel spell checker for the Malayalam language using deep learning is implemented. The tool comprises of both error detection and error correction. In [19], a mechanism for extracting named entities in Tamil Tweets is proposed. The system extracts Tamil texts from Twitter, tags unlabelled corpora and experiments with tri-gram embedding in word and glove model. In [20], attention-based mechanism is employed for developing English to Punjabi neural machine translation system. The work also includes a parallel corpus for English-Punjabi language pair. In [21], a new authorship analysis technique using style word pattern identification is proposed. The method enables identification of author traits in case of authors belonging to the same domain of interest thus providing a mechanism to resist manipulations of online posting activities.
Three papers are related to control and robotics. In [22], a design of a novel Nonlinear Fractional Proportional-Integral-Derivative (NLF-PID) for control of a two-link rigid manipulator is presented. The controller is developed by cascading a hyperbolic function of instantaneous state and current error with linear FO-PID scheme. In [23], a self-learning adaptive and optimal Lyapunov fuzzy Markov game controller for safe and stable tracking control of two-link robotic manipulators is proposed. In [24], the authors use Interval Type-2 fuzzy logic controller design to control chaos and associated instability in a nonlinear dynamical power system.
Another important area in decision making are the recommendation systems that provide suggestions based on previous usage behaviour. In [25], the authors present a recommender system that utilizes clickstream data. The proposed system predicts the preferences for the products clicked by the customers with the help of machine learning classifiers. In [26], the authors propose a community-based hashtag recommender system for twitter users. The work applies sentiment analysis for community detection using collaborative filtering. In [27], a parallel proactive cross-domain recommender system that helps to accelerate the computation in the multi-agent environment is proposed. In [28], the authors define fuzzy soft cardinality and fuzzy soft relative cardinality and discuss the related properties. Finally, the lattice ordered fuzzy soft group is applied in decision-making problems to find suitable solutions. In [29], a hybrid credit scoring model based on Neighborhood Rough Set and layered ensemble classification with weighted voting is proposed for computing the credit score.

In [45], the effect of gravitational perturbation forces on the orbital elements is discussed. Based on several experimental results, the authors conclude that the variations in semi-major axis affect the spatial representation of selected features registered in the satellite image data that have a direct bearing on the gravity-based perturbation forces.
Three papers are related to the software engineering field. In [46], a modelling framework for automotive software design and optimal test path generation scheme is proposed. In [47], the authors propose a fuzzy-based recommendation system that recommends programming skills and competency level of individuals based on eye movement data. In [48], the authors primarily explore the capability of evolution-based metrics when used in conjunction with object-oriented metrics for ascertaining change prone nature of classes. Four possible scenarios were evaluated for predicting change prone. The study also evaluates the use of seven machine learning techniques to determine change prone nature of classes in object-oriented software.
