Hybrid Satellite-Terrestrial Communication Networks for the Maritime Internet of Things: Key Technologies, Opportunities, and Challenges

With the rapid development of marine activities, there has been an increasing number of maritime mobile terminals, as well as a growing demand for high-speed and ultra-reliable maritime communications to keep them connected. Traditionally, the maritime Internet of Things (IoT) is enabled by maritime satellites. However, satellites are seriously restricted by their high latency and relatively low data rate. As an alternative, shore & island-based base stations (BSs) can be built to extend the coverage of terrestrial networks using fourth-generation (4G), fifth-generation (5G), and beyond 5G services. Unmanned aerial vehicles can also be exploited to serve as aerial maritime BSs. Despite of all these approaches, there are still open issues for an efficient maritime communication network (MCN). For example, due to the complicated electromagnetic propagation environment, the limited geometrically available BS sites, and rigorous service demands from mission-critical applications, conventional communication and networking theories and methods should be tailored for maritime scenarios. Towards this end, we provide a survey on the demand for maritime communications, the state-of-the-art MCNs, and key technologies for enhancing transmission efficiency, extending network coverage, and provisioning maritime-specific services. Future challenges in developing an environment-aware, service-driven, and integrated satellite-air-ground MCN to be smart enough to utilize external auxiliary information, e.g., sea state and atmosphere conditions, are also discussed

Emerging Technologies

This monograph investigates a multitude of emerging technologies including 3D printing, 5G, blockchain, and many more to assess their potential for use to further humanity’s shared goal of sustainable development. Through case studies detailing how these technologies are already being used at companies worldwide, author Sinan Küfeoğlu explores how emerging technologies can be used to enhance progress toward each of the seventeen United Nations Sustainable Development Goals and to guarantee economic growth even in the face of challenges such as climate change. To assemble this book, the author explored the business models of 650 companies in order to demonstrate how innovations can be converted into value to support sustainable development. To ensure practical application, only technologies currently on the market and in use actual companies were investigated. This volume will be of great use to academics, policymakers, innovators at the forefront of green business, and anyone else who is interested in novel and innovative business models and how they could help to achieve the Sustainable Development Goals.

Economically sustainable public security and emergency network exploiting a broadband communications satellite

The research contributes to work in Rapid Deployment of a National Public Security and Emergency Communications Network using Communication Satellite Broadband. Although studies in Public Security Communication networks have examined the use of communications satellite as an integral part of the Communication Infrastructure, there has not been an in-depth design analysis of an optimized regional broadband-based communication satellite in relation to the envisaged service coverage area, with little or no terrestrial last-mile telecommunications infrastructure for delivery of satellite solutions, applications and services. As such, the research provides a case study of a Nigerian Public Safety Security Communications Pilot project deployed in regions of the African continent with inadequate terrestrial last mile infrastructure and thus requiring a robust regional Communications Satellite complemented with variants of terrestrial wireless technologies to bridge the digital hiatus as a short and medium term measure apart from other strategic needs. The research not only addresses the pivotal role of a secured integrated communications Public safety network for security agencies and emergency service organizations with its potential to foster efficient information symmetry amongst their operations including during emergency and crisis management in a timely manner but demonstrates a working model of how analogue spectrum meant for Push-to-Talk (PTT) services can be re-farmed and digitalized as a “dedicated” broadband-based public communications system. The network’s sustainability can be secured by using excess capacity for the strategic commercial telecommunication needs of the state and its citizens. Utilization of scarce spectrum has been deployed for Nigeria’s Cashless policy pilot project for financial and digital inclusion. This effectively drives the universal access goals, without exclusivity, in a continent, which still remains the least wired in the world

The impacts of social media on leadership and organizational change in the U.S. Coast Guard : a first look

Thesis (M.B.A.)--Massachusetts Institute of Technology, Sloan School of Management, 2009.Statement of responsibility reads: by CDR James A. Passarelli, USCG.Includes bibliographical references (leaves 140-143).The U.S. Coast Guard faces a period of radical organizational change (known as "Modernization") in a time of asymmetrical threats to the U.S. and uncertain budget climates. In this time of uncertainty, a wave of New Media or Social Media (NSM) like blogs, social networking sites, file sharing and virtual worlds is sweeping the globe, connecting and networking people as never before. This thesis explores the impacts of New or Social Media on the U.S Coast Guard through two lenses: leadership and organizational change. There are three main themes to the thesis. First, I will present the reader with an introduction to New or Social Media along with a snapshot of the Coast Guard and its state of organizational change. Then, I will describe potential opportunities and challenges of NSM for the Coast Guard and strategies for leaders to engage in the medium. Lastly, I provide recommendations for NSM policies and actions for the Coast Guard going forward.James A. Passarelli.M.B.A

DRONE DELIVERY OF CBNRECy – DEW WEAPONS Emerging Threats of Mini-Weapons of Mass Destruction and Disruption (WMDD)

Drone Delivery of CBNRECy – DEW Weapons: Emerging Threats of Mini-Weapons of Mass Destruction and Disruption (WMDD) is our sixth textbook in a series covering the world of UASs and UUVs. Our textbook takes on a whole new purview for UAS / CUAS/ UUV (drones) – how they can be used to deploy Weapons of Mass Destruction and Deception against CBRNE and civilian targets of opportunity. We are concerned with the future use of these inexpensive devices and their availability to maleficent actors. Our work suggests that UASs in air and underwater UUVs will be the future of military and civilian terrorist operations. UAS / UUVs can deliver a huge punch for a low investment and minimize human casualties.https://newprairiepress.org/ebooks/1046/thumbnail.jp

Improving Capabilities and Strategic Fit in Governmental Agencies

A thesis submitted....The notion of Strategic Fit has been and remains to be one of the most important arguements in the fields of business strategy and strategic management. This research study examines the key concept of ‘strategic fit’ and its associated theories and seeks to investigate the causes that have created ‘strategic drift’ in Abu Dhabi’s governmental agencies in the infrastructure sector with the aim of improving their performance. However, for organisations, public or private, it still remains to be the most important notion and one that cannot be ignored because it is about the success of the organisation in its external environment where all competitive activity takes place. Thus, there are many underlying factors such as organisational culture, structure and organisational history that impact, or influence, the level of fit that organisations achieve. Therefore it is imperative that research is further undertaken on a deeper and wider level to fully understand the concept and importance of strategic fit and how it can be achieved. Hence, a research study in this area, especially in developing cities such as Abu Dhabi, is well justified and needed. The lack of strategic fit that has been witnessed in the Abu Dhabi’s infrastructure sector over the past few years continues to be, and it is a clear indication of a developing mismatch between the government and its policies and the agencies that implement them. However, this is clearly a major issue for the government going forward, if polices are developed with no clear understanding of the available resources and capabilities. Similarly, the study also seeks to determine why a strategic fit has not been achievable by the Abu Dhabi government. Though the government has developed policies to better serve its people, it continuously faces issues of policies not being implemented, or being implemented too late and targets not been met according to the original brief. It has been identified that there are numerous deficiencies between the various government agencies in the infrastructure sector in terms of keeping pace with governmental policies - consequently, resulting in strategic gaps with an increasing possibility of a possible strategic drift, if these issues are not addressed effectively and in a timely manner.The study further wishes to explore if strategic gaps have occurred as a result of inherent cultural, historical, political and/or structural aspects of the Abu Dhabi government and its numerous agencies – simply because these issues can be seen as preventative to change and progress which, in turn, can lead to strategic gaps and strategic drift in the long term. The research paradigm selected for this research study is that of the pragmatist approach and subsequently the key methodology employed throughout this research is that of the mixed methods. That mixed methods research is an intellectual and practical synthesis based on qualitative and quantitative research. Also, This research provides a summary of the important findings, proved hypotheses, achieved aim and objectives, and significant contribution to the knowledge of strategic management through the development of the “Community Innovation Scheme”, the “3-Spectrums of Change”, the “4Ms Change Model”; and the resulting framework model; the “Government Strategy Model”
