The control theory of nonlinear systems has been receiving increasing attention in recent years, both for its technical importance as well as for its impact in various fields of application. In this context, an alternative, frequency domain approach is pursued here. In the rest of this work, a specific system form of linearly decoupled but nonlinearly coupled subsystems is examined. The mathematical toolbox of the Hilbert transform is appropriately introduced for obtaining two low-pass subsystems that form an equivalent description of the essential overall system dynamics. The nonlinear coupled dynamics is investigated systematically by partitioning the coupled system state vector in such a way as to fully exploit the low-pass and the band-pass intrinsic features of free dynamics. In particular, by employing the Hilbert Transform, a low-pass equivalent system is derived. Then, a typical case is investigated thoroughly by means of numerical simulation of the original coupled low and band-pass, real-state-variable system and the low-pass-equivalent, complex-state-variable derived one. The nonlinear model equations considered here pave the way for a systematic investigation of nonlinear feedback control options designed to operate mechatronic transducers in energy harvesting, sensing or actuation modes.

The paper has three parts: Part-1: Design rules in nature, Mechanics and face of failure. Part-2: Lotus effect, Drag reduction in underwater vehicles, Tuna based oscillating propulsion mechanism, Murray’s law in manifolds and hydraulic circuits. Part-3: Design tools and Applications in Ocean Engineering. A numerical analysis is carried out on the viewport window to study the viewport behaviour at its corner. Acrylic viewport, pressure vessels, underwater thrusters, and pressure compensated hydraulic circuits are widely used components/sub-systems in ocean engineering. Stress reduction at corner of viewport and spherical shell is achieved by Biological Growth Method. Underwater forward propulsion in AUVs is inspired from Tuna based oscillating propulsion mechanism which is used by aquatic animals to propel in forward direction. Drag determination and reduction in underwater propulsion is very important criteria for thruster selection. It can be achieved by making surface texture as hydrophobic like Lotus which show self-cleaning property and tendency to remain dry called Lotus effect. Design of micro-fluidic systems is based on the bio-mimetic design rule of Murray’s law in hydraulic circuits which is obtained from the study of mammalian cardiovascular system’s vascular network. Therefore, many engineering problems like these can be solved by studying nature’s models and taking inspiration from them.

This tutorial aims to highlight the many ways in which accelerating climate change, overexploitation and mismanagement, and ever-growing marine pollution are transforming the chemical and physical characteristics of the world’s ocean basins. This ongoing chemical and physical transformation of the oceans will have profound implications for marine life, Earth’s climate, coastal human populations, and ocean-based economies around the world. The tutorial will discuss the wide-ranging adverse impacts of the ongoing changes in the marine food-web on the Blue Economy of India and other coastal and island nations around the world, and how the young citizens, entrepreneurs, conservationists, academics, policy makers and shapers, can affect change and contribute towards building a sustainable Blue Economy that protects and preserves our planet’s incredibly rich ocean biodiversity. By the end of the workshop the attendees would have learnt: 1. The multitude of ways in which climate change and other human interventions are changing the distribution of marine species in the world’s ocean basins. 2. The socio-economic consequences of these changes in the marine environment for India and other coastal and island nations. 3. The opportunities and mechanisms through which young citizens can contribute towards mitigating the human-caused stressors and conserving the rich ocean biodiversity.

Prior to joining the Foundation, Dr Bajaj worked as an independent science writer and researcher focusing on climate change and the environment where he published several articles on sustainable development, climate science, climate policy, and related areas. He received his PhD in Chemistry from the University of California, San Diego, USA, where he was a graduate student researcher for the NSF-funded Centre for Chemical Innovation – Center for Aerosol Impacts on Chemistry of the Environment based in San Diego, CA, USA.
Oxygen is an essential parameter in aquatic research, monitoring and aquaculture. With the introduction of oxygen optodes in 2002 the technical possibilities to measure O2 were enormously improved. Still many end users do not have a sufficient understanding of how to make oxygen measurements with sufficient quality and how to interpret the collected data. This tutorial is intended to present recent findings on oxygen dynamics and how sensors can be handled in the field to improve the data quality. The challenges of measuring in low oxygen environments and the shortcomings of the reference method, Winkler titration, will be discussed. Pressure effects on the sensing foils in deep water will be presented and results from new developments like trace O2 detection and more stable foils with better deep sea pressure behaviour will be presented.
Dr. Anders Tengberg

More than 25 years of experience in development and use of underwater technology. Work is reflected in more than 50 scientific publications. Since 1997 scientific advisor and product manager for water quality sensors at Aanderaa/Xylem in Norway and part time with oceanographic research at the University of Gothenburg/Chalmers University of Technology, Sweden.
The tutorial session will review the fundamental principles of marine vehicle control. Topics to be covered include: basic concepts in stability, controllability and observability; feedback linearization by dynamic inversion; nonlinear backstepping; control of under-actuated vehicles; sliding mode control and adaptive control.
Dr. Karl von Ellenrieder

From 2003 to 2016, he was with the Department of Ocean & Mechanical Engineering at Florida Atlantic University (USA) where, after being promoted through the ranks from Assistant Professor to Associate Professor, he ultimately served as a Full Professor of Ocean Engineering and as the Associate Director of the SeaTech Institute for Ocean Systems Engineering. His research interests include automatic control, the development of robotic unmanned vehicles, human-robot interaction and the experimental testing of field robots. Prof. von Ellenrieder is a member of the IEEE Oceanic Engineering Society and the IEEE Control Systems Society.
The ports developed in india are deepened from 9m to 14/16m so that Panamax vessels can be handled. Case studies of Visakhapatnam, Tuticorin and Haldia will be discussed. The design and construction methodology, while the existing berth is in operation and demotion of old structures by controlled blasting with monitoring of vibration of nearby structures will be highlighted for Visakhapatnam port. The proposal for deepening of VOC ( Tuticorin port) will be discussed. The methodology of integrating the block type structure with piled structure along with analysis and design training will be given. The lock gate free Haldia dock complex and the various studies carried out for opening a new entrance so that the vessels can be berthed will be presented. The modifications required in the existing structures will also be explained.
