At NTNU, small satellites are being built for maritime surveillance. Together with drones and vessels on and under water, information may be collected in a way that has never been done before. For example, poisonous algae can be discovered earlier, and farmed fish do not let go of life.

Now the combination of a variety of technologies can help us to monitor the processes in the ocean in a completely new way and to acquire new, necessary knowledge. For the first time, NTNU builds small satellites to be linked to autonomous subsea vessels (AUV), Autonomous Sea surface vessels (ASV) and unmanned airplanes (UAV).

- By combining all these technologies we can observe phenomena from different distances, with different types of sensors. This gives us a much larger range of information, "says Tor Arne Johansen and Kanna Rajan. They are both professors at the Department of Technical Cybernetics, and work at AMOS.

AMOS have through the last three years been using the artist BIIAS from Trondheim to provide music for the Polar night exhibition that is currently shown at Vitenskapsmuseet NTNU (open all days during the week). At the exhibition, BIIAS provided ambient soundscapes to illustrate marine life at the surface (seabirds and deep water fishes coming up to feed), high zooplankton activity and diurnal migration triggered by the extremely low light condition provided by diffuse light from the sun that is below the horizon, northern light and the moon. In addition, the exhibition with corresponding soundscapes shows the mass occurrence of organisms at the seafloor were reproduction is one of the major features.

Based on the soundscapes from “Polar night”, the year 2017 has been used to take these soundscapes to the next level, which now comprises 10 new songs. It is our hope that the original soundtrack ”Movements (Original Music for the “Polar Night” Exhibitions) created by BIIAS in collaboration with NTNU AMOS, will provide a platform for art in science. With its vibrant soundscapes and existential lyrics, the intention of “Movements” is to transport the listener into the polar night and complement science with artistic integrity to ease the communication of scientific research. It was published on March the 4th 2018 on all major music streaming services (eg. Spotify and ITunes).

By combining art and science, this project will work as a platform to pique people’s curiosity of the possibilities using enabling technology to generate new knowledge of the seascape and the matrix of organisms living in sea water, thus providing more answers to questions regarding life on Earth.

Of the 10 songs there are 5 instrumental soundscapes and 5 lyrical compositions all exploring peoples relationship with the sea, the depths, underwater robotics and marine biology. NTNU AMOS is planning to use the music in educational videos, TV productions, exhibitions and book projects. The AMOS professors with colleagues from Uit-The Arctic University of Norway and University of Delaware (USA) have signed a contract with Springer Verlag regarding a book about "Polar Night" and where the album "Movements" will give readers a new dimension by using this music while reading the book about enabling technology and the organisms living in the “dark ocean matrix”. The work was financed through NTNU Centre of Excellence ”Autonomous Marine Operations and Systems” (AMOS, NRC project 223254).

Use of an Autonomous Surface Vehicle reveals small-scale diel vertical migrations of zooplankton and susceptibility to light pollution under low solar irradiance

 

Abstract

Light is a major cue for nearly all life on Earth. However, most of our knowledge concerning the importance of light is based on organisms’ response to light during daytime, including the dusk and dawn phase. When it is dark, light is most often considered as pollution, with increasing appreciation of its negative ecological effects. Using an Autonomous Surface Vehicle fitted with a hyperspectral irradiance sensor and an acoustic profiler, we detected and quantified the behavior of zooplankton in an unpolluted light environment in the high Arctic polar night and compared the results with that from a light-polluted environment close to our research vessels. First, in environments free of light pollution, the zooplankton community is intimately connected to the ambient light regime and performs synchronized diel vertical migrations in the upper 30 m despite the sun never rising above the horizon. Second, the vast majority of the pelagic community exhibits a strong light-escape response in the presence of artificial light, observed down to 100 m. We conclude that artificial light from traditional sampling platforms affects the zooplankton community to a degree where it is impossible to examine its abundance and natural rhythms within the upper 100 m. This study underscores the need to adjust sampling platforms, particularly in dim-light conditions, to capture relevant physical and biological data for ecological studies. It also highlights a previously unchartered susceptibility to light pollution in a region destined to see significant changes in light climate due to a reduced ice cover and an increased anthropogenic activity.

Networks of Dissipative Systems: Compositional Certification of Stability, Performance, and Safety

Abstract:

Standard computational tools for control synthesis and verification do not scale well to large-scale, networked systems in emerging applications.  These lectures present a compositional methodology suitable when the subsystems are amenable to analytical and computational methods but the interconnection, taken as a whole, is beyond the reach of these methods. The main idea is to break up the task of certifying stability, performance, or safety for the network into subproblems of manageable size using dissipativity properties of the subsystems. Along the way we will introduce the notions of equilibrium-independent dissipativity as well as dissipativity with dynamic supply rates, and point to computational tools for verifying these properties.  We will illustrate the compositional approach with case studies in multi-agent systems and biological networks.

Ocean School of Innovation-workshop: Playing Lean Startup

7 December 2017 at 09:00 –16:00 
Scandic Lerkendal, Trondheim

Lean startup is a methodology for developing businesses and products, which aims to shorten product development cycles by adopting a combination of business-hypothesis-driven experimentation, iterative product releases, and validated learning. The central hypothesis of the lean startup methodology is that if startup companies invest their time into iteratively building products or services to meet the needs of early customers, they can reduce the market risks and sidestep the need for large amounts of initial project funding and expensive product launches and failures.

Playing Lean is both a serious board game and a great workshop format, hosted by Lean Startup practitioner Tore Rasmussen from the Norwegian University of Life Sciences.

Room B343, Elektro Bld., Gløshaugen

Abstract

In robust controller design, controllers intend to achieve the best control performance in the presence of the worst uncertainties, and the use of a high controller gain is the general method to handle the effect of uncertainties in nonlinear control theory. However, such a strategy causes massive control actions, so very powerful actuators are demanded to perform unnecessarily large control actions. Furthermore, the robust control performance is mostly obtained at a price of sacrificing the nominal control performance of the system, because the nominal control performance is not taken into account in robust controller design. Therefore, a control method is required to maintain the nominal control performance in the absence of uncertainties and exhibit robust control performance in the presence of uncertainties. In this talk, I will demonstrate two methods: 1) a real-time optimization-based nonlinear observer to estimate not only unmeasurable states but also unknown parameters 2) a self-learning disturbance observer. In the first method, a nonlinear moving horizon estimator is designed for systems that have constrained states and parameters. In the second method, the basic nonlinear disturbance observer is used in the estimation scheme for the self-learning disturbance observer to provide a conventional estimation law, which is used as being the learning error for the neuro-fuzzy system (NFS). Thus, the NFS learns uncertainties, and eventually takes the overall control of the estimation signal completely in a very short time and gives unbiased estimation results for the disturbance. A few real-time implementations on custom-design agricultural robotic systems will also be introduced.

Room B343, Elektro Bld. D, Gløshaugen

Abstract

Reachability analysis is critical for obtaining formal safety and performance guarantees for nonlinear and hybrid dynamical systems. However existing computational tools do not scale to models with more than a few state variables. In this talk we present a scalable procedure to compute tight over-approximations of reachable sets.  We first sample a number of trajectories of the system and next establish a tight bound on the divergence between the samples and neighboring trajectories using the concept of matrix measures from contraction theory. The divergence bounds also account for the accumulation of numerical simulation errors along simulation traces, which means that the proposed method provides a guaranteed over-approximation of the reachable set.  We demonstrate that the proposed technique scales well to systems with a large number of states.

Guest lecture by Andreas Bartl, Technical University of Munich, Germany, on Real-Time-Substructuring: Towards a Hardware-In-The-Loop approach in Structural Mechanics

27 April at 12:30-13:30
Havrommet (A1), Marine Technology Centre

Abstract

Real-Time-Substructuring is a Hardware-in-the-Loop technique in the domain of structural mechanics, which combines physical tests with simulations. Applied to noise, vibration and harshness problems, Real-Time-Substructuring allows testing components of complex systems and their effects under realistic boundary conditions. The method can be used in cases where the setup of the full system in the laboratory requires high efforts and costs or where the virtual component is modified frequently during the design process. The Hardware-in-the-Loop concept allows to take into account non-linear effects of the physical component as well as effects, which are not included in the model, such as temperature changes during the test. Real-Time-Substructuring can enable a rapid prototyping approach as modifications on the physical component show direct acoustic and vibrational effects on the physical system.

In the talk, current research on Real-Time-Substructuring at the Chair of Applied Mechanics at the Technical University of Munich will be presented. A use case, which is currently worked on, is the design process of an automotive transmission crossbeam. Additionally, control strategies for Real Time Substructuring, which are used at the Technical University of Munich will be presented.

Guest lecture by Prof. Jay Farrell, University of California, Riverside, USA, on "Reliable Precise State Estimation for Autonomous Highway Vehicles"

Room B343, Elektro Bld. D, Gløshaugen

Abstract

Autonomous and wirelessly connected vehicles face various challenges before effective commercial deployment. Key among these challenges is accurate and reliable awareness of world interactions. Awareness arises from onboard sensors and from ubiquitous communication between vehicles and infrastructure. Vehicle coordination and safety specifications necessitate reliable “where-in-lane” (i.e., decimeter accuracy) knowledge of vehicle position relative to other vehicles and the environment. This presentation will address vehicle state estimation with a focus on high precision and reliability.

Sensor fusion is critical to achieving these application requirements. Several of the sensors (e.g., vision, radar, Lidar, ultrasound, Global Navigation Satellite Systems (GNSS)) have various spurious measurement types. Standard Extended Kalman Filter (EKF) approaches are not sufficiently reliable at removing the effects of such spurious measurements because the EKF approach must decide at the time each measurement arrives whether it is valid. If deemed as valid, the measurement is used and discarded; otherwise it is not used and discarded. When that decision is wrong, either measurement information is lost or the state and covariance estimates are corrupted. Either situation can result in divergence of the EKF.

An alternative is to maintain all recent measurement data within a moving time-horizon. This window of data can be processed within a Bayesian framework to extract the optimal state trajectory estimate over the time-horizon. Because the time window of data is maintained it is straightforward to change the assumptions as to which data are valid and reprocess the data, allowing consideration of multiple fault scenario assumptions. Therefore, this approach is referred to as a Contemplative Real-Time (CRT) estimator. It is closely related to Moving Horizon Estimation (MHE) and Simultaneous Localization and Mapping (SLAM). This presentation will review the interrelationships between the EKF, Iterated Extended Kalman Filter (IEKF), and CRT within the Bayesian framework; discuss fault accommodation; present comparative experimental results; and discuss recent results on computationally efficient carrier phase integer ambiguity resolution over time windows.

Abstract:

Today we are witnessing a growing need to high-rate data transmission in underwater missions in a wide range of application areas. In particular, with the increasing use of robotics in underwater missions and the recent advances in the design and development of AUVs, there is an urgent need for broadband underwater links.  Recently, visible light communications have received particular attention due to their potential in providing very high-rate data transmission. In the challenging underwater context, the major impairments of the communication link include high beam attenuation, especially in high turbidity waters, and link misalignments. We provide an overview on VLC systems in underwater environments and explain the main considerations on the impact of the underwater channel and the transmission schemes. We present the current research activities in Fresnel Institute and also some future research directions for improving the performance and reliability of these links.
