The present work proposes a new class of model for random variables with support in the positive real line, this model explains the conditional quantile and is an alternative for modeling data that indicate asymmetric behavior and heavy tails. We present a new autoregressive moving average model based on the

τ

–th quantile of the Burr XII distribution (BXII-ARMA) since the quantile is less sensitive than the average of heterogeneous populations and also suitable in the presence of outliers. This model makes it possible to model any quantile by a dynamic structure containing autoregressive terms and moving averages, time-varying regressors, unknown parameters, and a link function. The conditional maximum likelihood method is considered to estimate the parameters and build the confidence intervals of the BXII-ARMA model. In addition, the model is adjusted to real data related to the financial market and compared with other competing models. Full article

In this paper, the effects of various fluid properties on two-dimensional unsteady biomagnetic fluid flow (blood) and heat transfer over a stretching sheet under the appearance of a magnetic dipole is investigated. The governing boundary layer equations are simplified via suitable transformation which are then solved using the bvp4c function approach in MATLAB software. The results indicate that fluid velocity and temperature are greatly influenced by the ferromagnetic interaction parameter. With increasing ferromagnetic number, fluid velocity drops but temperature increases. It is also found that the coefficient of skin friction and Nusselt number increase with an increase in values of thermal conductivity parameter. For certain parameter values, the results are also compared with previously published studies and they are found to be in acceptable agreement. Full article

The efficient compiling of arbitrary single-qubit gates into a sequence of gates from a finite gate set is of fundamental importance in quantum computation. The exact bounds of this compilation are given by the Solovay–Kitaev theorem, which serves as a powerful tool in compiling quantum algorithms that require many qubits. However, the inverse closure condition it imposes on the gate set adds a certain complexity to the experimental compilation, making the process less efficient. This was recently resolved by a version of the Solovay–Kitaev theorem for inverse-free gate sets, yielding a significant gain. Considering the recent progress in the field of three-level quantum systems, in which qubits are replaced by qutrits, it is possible to achieve the quantum speedup guaranteed by the Solovay–Kitaev theorem simply from orthogonal gates. Nevertheless, it has not been investigated previously whether the condition of inverse closure can be relaxed for these qutrit-based orthogonal compilations as well. In this work, we answer this positively, by obtaining improved Solovay–Kitaev approximations to an arbitrary orthogonal qutrit gate, with an accuracy

The Internet of Things (IoT) is a network of smart objects connected via the Internet, where each object is identified by a unique, accessible, and programmable address, while Blockchain is a technology for storing and transmitting information based on a decentralized system such that the centralized validation of transactions is replaced by a consensus mechanism. The integration of these two technologies requires consensus protocols to overcome the major challenges encountered in IoT systems, including issues related to security, storage capacity limits, computing power, etc. Therefore, different consensus algorithms have been implemented. For this purpose, this paper presents a research study on the criteria that would render a Blockchain consensus algorithm suitable for IoT networks, namely, computing power, latency, storage capacity, and security.

The objective of this article is to present a simulation of quantum information. We take advantage of quantum entanglement to ensure the spontaneous transfer of a state from one qubit to another similar qubit. Similarly, the principle of quantum teleportation is conceived in the application; it is not about transfer of matter, but of information. Indeed, two systems already exist, and at the end of the teleportation, the process is destructive—the first system will no longer be in the same state as the initial state and the second system takes the state of the first, which does not contradict the no-cloning theorem.

Blockchain technology is increasingly being used in the internet of things (BCoT: Blockchain for IoT) to ensure the security and reliability of data exchanged between connected devices. There are several generic blockchain architectures for IoT that differ in their network and consensus characteristics. Blockchain architectures for IoT can be compared based on various criteria such as the type of storage used, consensus, and security. They should be selected based on the specific needs of each use case, and the resource constraints of connected devices and security and resilience requirements. In this article, we present a review of blockchain architectures for the internet of things that have been studied and applied in some well-known contemporary applications. Full article

Kiln process fans play a crucial role in the cement manufacturing process. This article presents a study on the use of machine learning models to predict kiln process fan vibrations based on process fan running parameters. The study tested three different models, namely, k-nearest neighbors, linear regression, and random forest, and it found that all three could accurately predict fan vibrations. However, the random forest model performed the best due to its ability to handle non-linear relationships. The findings have significant implications for the maintenance and operation of kiln process fans, as predictive maintenance can reduce downtime and improve operational efficiency. Full article

Recent advances in artificial intelligence and natural language processing have been widely used in recent years, and one of the best applications of these technologies is conversational agents. These agents are computer programs that can converse with users in natural languages. Developing conversational agents using artificial intelligence techniques is an exciting prospect in natural language processing. In this study, we built an intelligent conversational agent using deep learning techniques. We used a sequence-to-sequence model with encoder–decoder architecture. This encoder–decoder uses a recurrent neural network with long–short-term memory cells. The encoder was used to understand the user’s question, and the decoder was to provide the answer.

Recommender Systems (RSs) have become essential for suggesting personalized recommendations to users across various fields, especially in tourism. Due to the rising popularity of mobile devices, mobile RSs have emerged as a potential research area. However, developing these systems into smart tourism mobile applications requires a significant investment in artificial intelligence experts and software engineering. Hence, to reduce the cost of this investment, we propose building a software factory that provides a robust set of assets such as domain-specific languages for accelerating the development process. To this aim, we apply a model-driven engineering approach that uses models, metamodels, and model transformations to support the designing and implementation of these software systems. In this paper, we introduce an overview of our software factory to support the development of several models of RSs. Full article

Conversational agents are being increasingly adopted in various domains, such as e-commerce and customer services, and as a direct communication channel between companies and end-users. Several tools have been developed to facilitate their definition and deployment. They exploit existing cloud infrastructures and artificial intelligence (AI) techniques to efficiently process users’ input and extract conversational information. Major Information Technology (IT) companies, such as Google, IBM, Microsoft, and Amazon, have provided powerful tools to develop conversational agents. Still, choosing the most appropriate tool is not easy, as it may require high costs associated with automatic natural language processing (NLP) services and expertise in software engineering and AI. Therefore, this paper aims to analyze different tools to help developers and non-developers to choose the optimal tool for their specific scenario of creating a conversational agent. Full article

Code-based cryptography is a promising candidate for post-quantum cryptography due to its strong security guarantees and efficient implementations. In this paper, we explore the use of code-based cryptography for multi-party computation and digital signatures, two important cryptographic applications. We present several efficient and secure code-based protocols for these applications, based on the McEliece cryptosystem and its variants. Our protocols offer strong security guarantees against both classical and quantum attacks, and have competitive performance compared to other post-quantum cryptographic schemes. We also compare code-based cryptography with other post-quantum schemes, including lattice-based and hash-based cryptography, and discuss the advantages and disadvantages of each approach.
