OCEANS 2020 - SINGAPORE
An OCEANS conference is a major forum for scientists, engineers, and end-users throughout the world to present and discuss the latest research results, ideas, developments, and applications in all areas of oceanic science and engineering. Each conference has a specific theme chosen by the conference technical program committee. All papers presented at the conference are subsequently archived in the IEEE Xplore online database. The OCEANS conference comprises a scientific program with oral and poster presentations, and a state of the art exhibition in the field of ocean engineering and marine technology. In addition, each conference can have tutorials, workshops, panel discussions, technical tours, awards ceremonies, receptions, and other professional and social activities.

Computer is a resource that practitioners, researchers, and managers can rely on to provide timely information about current research developments, trends, best practices, and changes in the profession.
Physics, medicine, astronomy—these and other hard sciences share a common need for efficient algorithms, system software, and computer architecture to address large computational problems. And yet, useful advances in computational techniques that could benefit many researchers are rarely shared. To meet that need, Computing in Science & Engineering (CiSE) presents scientific and computational contributions in a clear and accessible format. ...

Since 1982, Landsat has acquired multispectral data using 8-bit data. With many new and highly advanced systems and sensors being developed, we wish to evaluate the benefits of higher radiometric precision for forestry applications. Two industrial forestry sites in central Virginia are chosen to carry out this analysis because of the large variability in standing biomass associated with recovery from ...

The High Resolution Imaging Spectrometer (HIRIS) is a remote sensing instrument which will be placed on board the first NASA Polar Orbiting Platform (NPOP-1), as part of the Earth Observing System (EOS). HIRIS is an F/5.4 aperture spectrometer with a focal length of about 1222 mm, and uses a precision two-axis gimballed pointing mirror system to image and track targets. The instrument is in early development and is scheduled for launch in 1998. Gimbal position and rate sensors provide the feedback signals to maintain the pointing accuracy at 585 arcsec (peak-to-peak), and the pointing stability at less than 2.65 arcsec in 33 msec. A state-space controller implemented with a digital computer is used to provide a position loop bandwidth of 1 Hz and a rate loop bandwidth of 7 Hz. This paper will address the design concept developed for the HIRIS pointing system, including an overview of the system design, flight hardware and software. In addition, a simulation assessment of the pointing system that takes into consideration issues such as non-linear effects, sensor noise, and non - collocated sensors and actuators in a flexible structure, will be discussed.
Since 1982, Landsat has acquired multispectral data using 8-bit data. With many new and highly advanced systems and sensors being developed, we wish to evaluate the benefits of higher radiometric precision for forestry applications. Two industrial forestry sites in central Virginia are chosen to carry out this analysis because of the large variability in standing biomass associated with recovery from past harvest. IKONOS imagery and Earth Observing System's Advanced Land Imager (ALI) imagery are used in the study. These sensors acquire data using 11 and 12 bits, respectively. By subsampling to Landsat spatial resolution, and truncating the dynamic range and radiometric resolution, we can create Landsat-like image products at a variety of radiometric resolutions. Results show that although a difference can be seen when comparing datasets of higher and lower radiometric resolution, those differences appear to be small when trying to discriminate the boundaries of disturbed stands.
AVHRR data have been extensively used for global land cover classification, but few studies have taken direct and full advantage of the multiyear properties of AVHRR data. The authors generated three types of signatures from 12-year monthly composite NDVI (normalized difference vegetation index) and channel 4 brightness temperature (T/sub 4/) of NOAA/NASA Pathfinder AVHRR Land data for land cover classification. Both quadrature discriminate analysis (QDA) and linear discriminate analysis (LDA) are explored for classification. A global land cover training database created from Landsat TM and MSS imagery is used for training and validation. It turns out that QDA performs much better than LDA, and the overall classification rate is as high as 95.9%.
The High Energy Physics community has been developing dedicated solutions for processing experiment data over decades. However, with recent advancements in Big Data and Cloud Services, a question of application of such technologies in the domain of physics data analysis becomes relevant. In this paper, we present our initial experience with a system that combines the use of public cloud infrastructure (Helix Nebula Science Cloud), storage and processing services developed by CERN, and off-the-shelf Big Data frameworks. The system is completely decoupled from CERN main computing facilities and provides an interactive web-based interface based on Jupyter Notebooks as the main entry- point for the users. We run a sample analysis on 4.7 TB of data from the TOTEM experiment, rewriting the analysis code to leverage the PyRoot and RDataFrame model and to take full advantage of the parallel processing capabilities offered by Apache Spark. We report on the experience collected by embracing this new analysis model: preliminary scalability results show the processing time of our dataset can be reduced from 13 hrs on a single core to 7 mins on 248 cores.
A new pulse characterization concept capable to measure the absolute value of carrier-envelope phase has been demonstrated. Complete waveforms of sub- single-cycle pulses were characterized by using the method.
A new control approach for bidirectional DC-DC (BDC) converter is proposed in this paper. This approach aims at controlling a BDC in such a way that makes it behaves like a multi-level virtual conductor. As a matter of fact, the voltage difference between the terminals of any conductor is zero volts. Conversely, the main target of the proposed control approach is to keep the voltage difference between the converter terminals constant at certain value. In other words, the proposed control approach permits the DC-DC converter to transfer the power between two nodes at different voltage levels. In this way, the converter performs like a conductor but unlike the normal conductor, it has voltage deference between its terminals. Thus, the authors call it virtual conductor. This virtual conductor is considered a base to a power routing in dc networks; since it has the ability of transferring the electric power between nodes at different voltage levels. Furthermore, it allows an easy plug-and-play feature. The proposed BDC system configuration has been investigated analytically, using simulation, and experimentally.
