Algorithms, Networking and Sensing for Data Processing, Mobile Computing and Applications
(Wydawnictwo Politechniki Łódzkiej, 2016) Sankowski, Dominik; Romanowski, Andrzej; Sikora, Jan; Wiatr, Kazimierz; Ostalczyk, Piotr
It is an exciting time to be a computer scientist. The multitude of new data sources, sensing methods and the abundance of processing power create new opportunities of which we would never have thought before. This monograph is addressed to the students and researchers who are excited by this perspective. We contribute a carefully selected collection of research activities that aim at using applied computer science to solve some challenges of the modern world and effectively use the potential of information technology. We hope that the chapters included in this book will illustrate how computer science can help us understand the world and achieve our goals more effectively. That is why we have included works that deal with the computational aspects of physical processes. Furthermore, the book also addresses the timely challenges produced by the emergence of mobile computing as the most common interaction paradigm. We also look into future technologies by preparing for the time of pervasive robot assistants. Finally, many chapter of this monograph address data processing. We believe that contributions in this area are particularly relevant as making sure that the abundance of data generated by computational artefacts around us is used effectively is bound to be crucial in deterring how our lives will look in the near future. The topics addressed here are certainly worth a reflection. We hope that this book will inspire the reader to conduct further research with a futuristic outlook.

Carbon Footprint Reduction of a Petrochemical Process Supported by ML and Digital Twin modelling
(Wydawnictwo Politechniki Łódzkiej, 2023) Kulikowski, Sławomir; Romanowski, Andrzej; Sierszeń, Artur
This article aims to present a concept of an Artificial Intelligence application in the form of pre-trained Machine Learning modules to reduce the carbon footprint of a chemical recycling process. Chemical recycling of plastic is energy-consuming as it requires relatively high temperatures and calibration cycles based on a constantly changing structure of raw materials. Due to that fact, complex process parameters must be tuned to allow the production of the required fraction of gasoline. In general, the designed IoT system enables a massive collection of technology and environmental data and the processing of parameters to feed the Digital Twin of a petrochemical plant. The scientific part of the project consists of Digital Twin modelling, experiments, simulations, and training of machine learning modules to predict the optimal set of production line parameters based on the specific structure of raw materials to reduce the number of calibrations and lower energy consumption indirectly which will lead to carbon footprint reduction. There is an here is an estimate that that deployed solution will allow reduction of energy consumption on a monthly level of 10-15% which could generate direct savings on a cost of energy but also savings in a field of carbon emission and related credits. The project also includes the evaluation of predictions supported by machine learning modules, training techniques and comparison to expert settings to assess the quality of the application.

Computerised systems pervade our everyday lives. We see computers everywhere we go. We wake up to the sound of an electronic alarm clock and go to sleep just after switching off the e-book reader. Academic research keeps pursuing solutions to more and more problems using computational methods. With so many new systems around us that attempt to solve so many problems, it becomes harder and harder to identify the truly valuable solutions. How does a modern engineer find what are the latest developments can affect their work? In this book, we provide research results in a variety of application domains that illustrate how computer science may contribute to solving engineering problems. We address a broad spectrum of applications including finance, computer networks, office environments and 3D graphics to show how versatile computer algorithms can be. We aim to stress that applied computer science produces best results when practiced as an interdisciplinary science in close cooperation with application domain specialists. We hope that this monograph will inspire many researchers and students to conduct new interesting activities to further advance the field of computer science. The readers are welcome to use the chapters of this book as starting points of extended discussions that may lead to new ideas and discoveries. We encourage interested readers to contact the authors to fuel the discussions with hands-on experiences and extended work.
