Unmanned Vehicle Systems & Operations on Air, Sea, Land

Unmanned Vehicle Systems & Operations On Air, Sea, Land is our fourth textbook in a series covering the world of Unmanned Aircraft Systems (UAS) and Counter Unmanned Aircraft Systems (CUAS). (Nichols R. K., 2018) (Nichols R. K., et al., 2019) (Nichols R. , et al., 2020)The authors have expanded their purview beyond UAS / CUAS systems. Our title shows our concern for growth and unique cyber security unmanned vehicle technology and operations for unmanned vehicles in all theaters: Air, Sea and Land – especially maritime cybersecurity and China proliferation issues. Topics include: Information Advances, Remote ID, and Extreme Persistence ISR; Unmanned Aerial Vehicles & How They Can Augment Mesonet Weather Tower Data Collection; Tour de Drones for the Discerning Palate; Underwater Autonomous Navigation & other UUV Advances; Autonomous Maritime Asymmetric Systems; UUV Integrated Autonomous Missions & Drone Management; Principles of Naval Architecture Applied to UUV’s; Unmanned Logistics Operating Safely and Efficiently Across Multiple Domains; Chinese Advances in Stealth UAV Penetration Path Planning in Combat Environment; UAS, the Fourth Amendment and Privacy; UV & Disinformation / Misinformation Channels; Chinese UAS Proliferation along New Silk Road Sea / Land Routes; Automaton, AI, Law, Ethics, Crossing the Machine – Human Barrier and Maritime Cybersecurity.Unmanned Vehicle Systems are an integral part of the US national critical infrastructure The authors have endeavored to bring a breadth and quality of information to the reader that is unparalleled in the unclassified sphere. Unmanned Vehicle (UV) Systems & Operations On Air, Sea, Land discusses state-of-the-art technology / issues facing U.S. UV system researchers / designers / manufacturers / testers. We trust our newest look at Unmanned Vehicles in Air, Sea, and Land will enrich our students and readers understanding of the purview of this wonderful technology we call UV.https://newprairiepress.org/ebooks/1035/thumbnail.jp

UNMANNED UNDERWATER VEHICLE MISSION SYSTEMS ENGINEERING PRODUCT REUSE RETURN ON INVESTMENT

Unmanned Underwater Vehicles (UUVs) accomplish a wide spectrum of missions ranging from generic to extremely specific. Although not all UUVs can accomplish all missions, there is significant replication of the requirements and the systems across the family of UUVs. The design process for UUVs balances operational requirements, design feasibility, expected performance, schedule, budget, and ultimate system and life-cycle costs. The U.S. Department of Defense does not have an established process for developing UUV Systems Engineering (SE) requirements. This results in duplicative development efforts adding unnecessary costs to UUV programs. This paper investigates the SE requirements and interfaces across various UUV mission spaces to establish complexity and reuse weights. A Constructive SE Cost Model (COSYSMO) is applied to determine the cost advantage to reuse SE requirements for UUV assets across different mission spaces to determine an overall SE effort. Requirements from the baseline mission are then compared with requirements from eight other missions, and the efforts compared to determine a return on investment (ROI) for using previous missions as a baseline. Utilizing the resulting UUV requirement cost versus ROI can serve as a starting point for future UUV program concept design.Civilian, Department of the NavyCivilian, Department of the NavyCivilian, Department of the NavyCivilian, Department of the NavyCivilian, Department of the NavyApproved for public release.

Investigate how construction waste generation rate is, different for every types of project in peninsular Malaysia, using site visit method

Malaysia is a rapid development of its urban centre, and where construction and demolition (C&D) waste generation is increasing proportionally with the new construction industry development. In Malaysia, the most crucial issue highlighted by local researchers is excessive of C&D waste generation. The transfer of construction and demolition waste at landfills has brought about major ecological concerns and government sources demonstrate that there is an intense lack of landfill space in Malaysia. The aim of this study is to investigate the construction waste generation rate in Malaysia due to different project types. To obtain the waste generation rate, construction sites visit is required. In construction site, direct and indirect approaches were utilized to collect C&D waste generation data based on data available. For the construction waste generation rate, nonresidential projects obtained smallest value such as 0.008 t/m2 while residential projects obtained highest value such as 0.016 t/m2. Social amenities obtained 0.010 t/m2 of waste generation rate. Waste generation rate is different compare to waste generation due to projects sizes. Waste generation rate shows the actual waste generation for every projects type based on gross floor area. The gross floor area is important parts need to be considered during waste generation which provide actual waste generation data. Waste generation rate plays an important role to measure waste generation for every type of projects. This study, will be very much beneficial for contractors and clients to control the construction waste in construction site and to identify efficiencies of projects using waste generation rate. Besides that, provide a generation rate on construction waste to the Government for control the waste and reduce illegal dumping in future
