Tutorials

OCEANS 2024 is offering tutorials for attendees at a nominal charge, with the purpose of expanding the attendees’ knowledge of key technologies or emerging areas of technology and research. The tutorial sessions will be conducted on 15th April, 2023. The sessions will be held in-person only.

With speakers/instructors providing rare insights into the subject and covering both theoretical & practical aspects in sufficient depth, tutorials are expected to benefit academia and industry. The list of tutorials proposed to be conducted subject to enough interest from registering attendees, is given below.

CEU credits. One of the benefits of offering Professional Tutorials is that attendees can acquire Continuing Education Units (CEU) for an accreditation tutorial which assists the attendee in career development. There will be a fee of SGD 10 per tutorial for CEU applications.

Meals or refreshments will not be provided for tutorial attendees – you are required to make your own arrangements for this during the tea/lunch breaks. Tutorial materials will be made available to attendees before the beginning of the conference.

Note that if a certain minimum number of delegates do not sign up for a tutorial session, we will choose not to proceed with the session.

The deadline for submission of Tutorial proposals has closed.

Feel free to contact the tutorial chair at technical-chair@singapore24.oceansconference.org with any questions.

List of Tutorials

Presenter(s): Prof. Roee Diamant, University of Haifa, Israel

Description:

In this tutorial, we will examine the theoretical foundation of underwater acoustic signal detection and offer some practical techniques. We will introduce the existing noise models, and discuss ways to estimate their parameters. Based on these, several theoretical bounds for detection performance will be presented. Traditional and state-of-the-art detection schemes will be studied, and analyzed by their suitability to the underwater domain. We will then focus on tailor-made solutions for both active and passive underwater signal detection, and show some test cases on practical applications. In the second part, the attendees will practice on detection of signals over both simulations and using real signals recorded at sea. Finally, the current research challenges will be reviewed.

The objectives are:

  1. Introduce basic approaches for underwater acoustic signal detection.
  2. Study practical noise distribution model for signal detection.
  3. Discuss current schemes for underwater acoustic signal detection.
  4. Experience techniques for signal detection.

The classes will include both theoretical analysis, simulation results, and a first-hand experience of acoustic detection of the participants over experimental data. The workshop is targeted to electrical and computer engineers who have a background on random processes, telecommunication, signals and systems, and probability analysis. The topics covered are highly relevant to engineers working on a variety of acoustic applications including the broad topics of: Sonar imaging, Underwater acoustic communications, Underwater localization, Event detection and Analysis of acoustic sensor data.

Description:

This is a half-day tutorial that provides an overview of current AUV technologies and operations. The objective is to equip participants to navigate the complexities of AUV technology by establishing a basic understanding of what currently available AUV systems can provide for oceanographic applications. The first half will cover AUV anatomy and terminology, a comparative overview of diverse AUV styles, and consideration of mission planning and real-world at-sea operations. The second half will dive deeper into vehicle architecture, payloads, survey optimization, and navigation options. It will culminate in a survey of advanced applications and current research in the field. Key points will be illustrated by applications and results from the Monterey Bay Aquarium Research Institute’s (MBARI) Dorado AUV and Long Range AUV operations.

The course is intended for those without substantial prior experience working with AUVs. It is suitable for anyone with familiarity with one or more engineering disciplines and/or oceanographic operations who is looking for a broad topic overview. It may be of particular interest to researchers or industry professionals looking to understand how AUV data might be useful for their work. Additionally, it is suitable for engineers who primarily work with other types of platforms, or students looking for an introduction to the field.

Attendees will gain basic understanding of AUV types, technologies, terminology, and navigation techniques, including discussion of the comparative strengths of AUVs and alternative methods of data collection. Attendees will also be provided an understanding of tradeoffs in AUV operations, including power estimation, endurance considerations, and mission structure to acquire the desired data sets. Previous iterations of this tutorial have shown that it is best suited to a class size of ten to twenty people, to allow time for discussion of participants’ particular areas of interest.

Quinn Shemet is a research engineer at the Monterey Bay Aquarium Research Institute (MBARI). At MBARI, Quinn works on development and operation of the Long Range AUV, an upper-water-column AUV designed primarily for biological and chemical sensing, and associated payloads.

Length: Half-day

Time: 0900-1230

Requirements for attendees: (Will be updated soon)

Description:

The tutorial starts with a short presentation of our laboratory, our projects and the motivation for automatic control and adaptability in automatic control of marine systems. In addition, an introduction to model predictive control with its variants, strengths and weaknesses is given. After a short break, participants will familiarize themselves with the simulated vessels and vessel identification methods required for predictive control. With successfully identified models, the participants will explore the influence of different optimization parameters on the model-based predictive controller.

Once the controller has been realized, control synthesis will be explored in a completely data-driven fashion. First, a theoretical background with requirements and conditions that ensure the feasibility of direct data-driven controllers will be presented. After a short discussion and a break, the participants will learn about the planned data-driven controller and will fill out the missing pieces required for the controller application. After implementation, participants will test the quality of the controller, observe the impact of the controller parameters on the quality of the control scheme and compare the results with the model-based predictive controller.

Luka Mandić received a Master’s degree in Electrical Engineering from the University of Zagreb, Faculty of Electrical Engineering and Computing, Zagreb, Croatia, in 2018. He is currently working in the Laboratory of Underwater Systems and Technologies at the Department for Control Engineering and Computing in Zagreb, where he is currently pursuing his PhD.
