AI and Chatbots in FinTech: Revolutionizing Digital Experiences and Predictive Analytics
No full textThis book is a comprehensive guide to the use of Artificial Intelligence (AI) in the Financial Technology (FinTech) industry. It is comprised of ten chapters, each addressing a specific aspect of AI in FinTech. The reader is introduced to AI in FinTech, including its history and current state and the role of chatbots in FinTech and how they are used to improve customer service. Furthermore, the book explores the business framework of AI-based ChatGPT in FinTech, including the technology behind ChatGPT and how it can be applied to various financial sectors. The book examines the use of predictive analytics and machine learning in FinTech, highlighting how these tools are used to predict customer behavior and improve decision-making. The author delves into how ChatGPT is used to determine buying behavior and discusses the use of machine learning to reshape the digital experience in FinTech. Additionally, the book provides best practices for retaining customers in FinTech, including how to use AI to create personalized experiences that keep customers coming back, and explores the different applications of predictive models in FinTech, including how they are used to improve risk management and fraud detection. Lastly, the book discusses the use of ChatGPT for stock price prediction and the detection of financial fraud and examines the role of ChatGPT in the world of cryptocurrency, including how it can be used to make informed investment decisions. Overall, this book provides a comprehensive overview of the different ways AI is being used in FinTech and the potential it holds for improving customer experiences and driving innovation in the financial industry
Well-posedness of slightly compressible Boussinesq’s flow in Darcy–Bénard problem
No full textIn the present article, we show the existence, uniqueness, and behavior in time of solutions to the Darcy–Bénard
problem for an extended-quasi-thermal-incompressible fluid (extended Darcy–Bénard problem) uniformly heated from below,
modeling the phenomenon of thermal convection in porous media. First and foremost, for the sake of a more realistic
description of the phenomenon under analysis, we here assume the fluid’s density to depend on pressure and temperature,
unlike the classical problem where the density is solely a function of temperature. This new constitutive law for the density,
proposed by Guoin and Ruggeri in 2012, arises as a necessary requirement for the thermodynamic consistency of the model
and introduces a slight compressibility making the model more closely aligned with reality. Moreover, the dependence of
the fluid density on both temperature and pressure fields, from the mathematical viewpoint, adds an interesting challenge,
requiring a new approach for its resolution. The well-posedness results establish a foundation for further analyses of the
hydrodynamic stability properties of the solutions of the extended Darcy–Bénard problem, with particular regard to the
effect of compressibility factor, which has great interest in applications
Dispute Resolutions for Digital Assets in a Decentralized Virtual World
Full text linkDigital assets and the Metaverse have transformed our interactions and business practices. This dynamic environment, comprising virtual worlds and online communities, facilitates the creation, sharing, and consumption of digital information. As the Metaverse grows, disputes over digital assets pose challenges for traditional dispute resolution. Thus, this study explores the need for effective dispute resolution, focusing on digital assets, decentralization, digital evidence, and proposing a structure for decentralized resolution
A Comprehensive Study of Cryptocurrencies as a Financial Asset: Major Topics and Market Trends
No full textThe article comprises a set of theoretical and methodological approaches to studying the concept of “cryptocurrencies as a financial asset and market trends.” and identifies some trends of development of the real sector in the project financing market. This paper provides a systematic review of the empirical literature based on the major topics that have been associated with the market for cryptocurrencies since their development as a financial asset. It also presents an overview of the advantages of current trends in the market. Each influences the perception of the role of cryptocurrencies as a credible investment asset class and legitimate value. We posit that cryptocurrencies may perform some useful functions and add economic value, but there are reasons to favor the regulation of the market. While this would go against the original libertarian rationale behind cryptocurrencies, it appears a necessary step to improve social welfare
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variable gravity effects on penetrative porous convection
No full textThe effect of variable gravity on the onset of penetrative convection in a horizontal fluid-saturated porous layer is studied, performing the linear instability analysis and the nonlinear stability analysis (via the weighted energy method) of the thermal conduction solution. The linear and nonlinear critical Rayleigh numbers for the onset of penetrative porous convection are determined and their behaviour with respect to the fundamental physical parameters of the model is studied. In particular, we found that there exists a region of subcritical instabilities and that the increase of the upper bounding plane temperature and the decrease of gravity have a stabilizing effect on the onset of convection
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
