    The Web of Things (WoT) is slowly gaining grounds and through the properties of barcodes, QR codes, RFID, active sensors and IPv6, objects are fitted with some form of readability and traceability. People are becoming part of digital global network driven by personal interests. The feeling being part of a community and the constant drive of getting connected from real life finds it continuation in digital networks. This paper investigates the concepts of the internet of things from the aspect of the autonomous mobile robots with an overview of the performances of the currently available database management systems

    Exploring the Synergy between Industry 4.0, Quality 4.0, and Lean Production for Improved Quality in Manufacturing

    Get PDF
    The manufacturing industry has experienced significant changes with the advent of technological advancements. Industry 4.0 and Quality 4.0 have emerged as new paradigms focusing on the use of digital technologies to enhance efficiency and quality in manufacturing. Additionally, the long-established lean approach aims to minimize waste and improve overall quality. Integrating these approaches with Industry 4.0 and Quality 4.0 has the potential to transform the industry by optimizing quality, efficiency, and profitability. Therefore, this study aims to explore the interconnections between lean, Industry 4.0, and Quality 4.0, and their impact on quality in manufacturing. The research begins by providing the necessary background, starting with a comprehensive examination of the concept of quality. Subsequently, the study presents an overview of lean principles, followed by an analysis of the concepts of Industry 4.0 and Quality 4.0. The theoretical framework also explores the relationship between these concepts. Following the theoretical analysis, the empirical part of the study was conducted using a survey questionnaire. The survey was distributed to 190 medium-sized manufacturing companies in Finland, ultimately receiving responses from 44 organizations. This survey aimed to gather practical insights into the implementation of lean, Industry 4.0, and Quality 4.0 practices within the manufacturing context. Based on the findings derived from the survey data, lean tools have a broader adoption compared to Industry 4.0 and Quality 4.0 practices. Moreover, implementing these tools and practices has shown a positive impact on company performance, sparking a growing interest among companies to explore and implement additional tools. The survey also highlights a strong inclination among organizations to embrace Industry 4.0 and Quality 4.0 practices, showcasing their increasing recognition of the potential benefits and transformative capabilities of these innovative methodologies in driving organizational success

    Shuttle Ground Operations Efficiencies/Technologies (SGOE/T) study. Volume 2: Ground Operations evaluation

    Get PDF
    The Ground Operations Evaluation describes the breath and depth of the various study elements selected as a result of an operational analysis conducted during the early part of the study. Analysis techniques used for the evaluation are described in detail. Elements selected for further evaluation are identified; the results of the analysis documented; and a follow-on course of action recommended. The background and rationale for developing recommendations for the current Shuttle or for future programs is presented

    Research and technology: 1994 annual report of the John F. Kennedy Space Center

    As the NASA Center responsible for assembly, checkout, servicing, launch, recovery, and operational support of Space Transportation System elements and payloads, the John F. Kennedy Space Center is placing increasing emphasis on its advanced technology development program. This program encompasses the efforts of the Engineering Development Directorate laboratories, most of the KSC operations contractors, academia, and selected commercial industries - all working in a team effort within their own areas of expertise. This edition of the Kennedy Space Center Research and Technology 1994 Annual Report covers efforts of all these contributors to the KSC advanced technology development program, as well as our technology transfer activities. The Technology Programs and Commercialization Office (DE-TPO), (407) 867-3017, is responsible for publication of this report and should be contacted for any desired information regarding the advanced technology program

    Marshall Space Flight Center Research and Technology Report 2019

    Today, our calling to explore is greater than ever before, and here at Marshall Space Flight Centerwe make human deep space exploration possible. A key goal for Artemis is demonstrating and perfecting capabilities on the Moon for technologies needed for humans to get to Mars. This years report features 10 of the Agencys 16 Technology Areas, and I am proud of Marshalls role in creating solutions for so many of these daunting technical challenges. Many of these projects will lead to sustainable in-space architecture for human space exploration that will allow us to travel to the Moon, on to Mars, and beyond. Others are developing new scientific instruments capable of providing an unprecedented glimpse into our universe. NASA has led the charge in space exploration for more than six decades, and through the Artemis program we will help build on our work in low Earth orbit and pave the way to the Moon and Mars. At Marshall, we leverage the skills and interest of the international community to conduct scientific research, develop and demonstrate technology, and train international crews to operate further from Earth for longer periods of time than ever before first at the lunar surface, then on to our next giant leap, human exploration of Mars. While each project in this report seeks to advance new technology and challenge conventions, it is important to recognize the diversity of activities and people supporting our mission. This report not only showcases the Centers capabilities and our partnerships, it also highlights the progress our people have achieved in the past year. These scientists, researchers and innovators are why Marshall and NASA will continue to be a leader in innovation, exploration, and discovery for years to come

    Get PDF
    The unprecedented Covid-19 crisis revealed the scale and scope of a new type of economy taking shape in front of our very eyes: the digital economy. This book presents a concise theoretical and conceptual framework for a more nuanced analysis of the economic and sociological impacts of the technological disruption that is taking place in the markets of goods and services, labour markets, and the global economy more generally. This interdisciplinary work is a must for researchers and students from economics, business, and other social science majors who seek an overview of the main digital economy concepts and research. Its down-to-earth approach and communicative style will also speak to businesses practitioners who want to understand the ongoing digital disruption of the market rules and emergence of the new digital business models. The book refers to academic insights from economics and sociology while giving numerous empirical examples drawn from basic and applied research and business. It addresses several burning issues: how are digital processes transforming traditional business models? Does intelligent automation threaten our jobs? Are we reaching the end of globalisation as we know it? How can we best prepare ourselves and our children for the digitally transformed world? The book will help the reader gain a better understanding of the mechanisms behind the digital transformation, something that is essential in order to not only reap the plentiful opportunities being created by the digital economy but also to avoid its many pitfalls
