X-Band/C-Band-Comparison of Ship Wake Detectability

, 2020
Recent studies investigated the detectability of ship wake signatures on SAR imagery using a large number of SAR images collocated with Automatic Identification System data for training machine learning models. These detectability models are in agreement with oceanographic expectations from preceding studies and can therefore be used for comparing the ...

Toward Carbon Accounting and Circular Harmony in Shipping Corporations: A Systematic Bibliometric Review

Business Strategy and the Environment, EarlyView.
ABSTRACT This study examines how carbon accounting can be used to govern, not merely report, circular economy principles in shipping corporations. Grounded in institutional theory and aligned with the UN 2030 Agenda, this study introduces circular harmony as an accounting design principle: Circular interventions are embedded in a single well‐to‐wake ...

Advances in Triboelectric Nanogenerators With Rotating Structure

Carbon Energy, EarlyView.
The rotating TENG has been widely studied for its superiorities of simple structure, high efficiency, and stable output. This review introduced the four different principles of rotating TENG and offered a thorough summary for performance and application research through three‐level classification. Importantly, the current existing problems, challenges,

Confronting Technological and Tactical Change: Allied Anti-Submarine Warfare in the Last Year of the Battle for the Atlantic [PDF]

, 2012
The recall of German U-boat wolfpacks from the central north Atlantic at the end of May 1943 ended the most costly phase of the shipping war for the Allies. Never again would the German U-boats inflict dangerously high shipping losses.

Ship-Iceberg Discrimination in Sentinel-2 Multispectral Imagery by Supervised Classification [PDF]

, 2017
The European Space Agency Sentinel-2 satellites provide multispectral images with pixel sizes down to 10 m. This high resolution allows for fast and frequent detection, classification and discrimination of various objects in the sea, which is relevant in

Simulations of Photovoltaic Systems on Different Types of Ships in Sweden: Solar Energy Generation, Comparison to Energy Consumption, and Reduction of CO2 Emission

Energy Science &Engineering, EarlyView.
Investigation of the potential of using solar cells on different types of ships, to see how it reduces energy consumption and emissions of carbon dioxide (CO2). From the reduction in fuel consumption, the fuel cost reduction was estimated, and an approximate payback time for the solar cell system was calculated.

Low X-Ray Luminosity Galaxy Clusters: Main goals, sample selection, photometric and spectroscopic observations [PDF]

, 2016
We present the study of nineteen low X-ray luminosity galaxy clusters (L$_X \sim$ 0.5--45 $\times$ $10^{43}$ erg s$^{-1}$), selected from the ROSAT Position Sensitive Proportional Counters (PSPC) Pointed Observations (Vikhlinin et al.

Design of HAWT Rotor for Non‐Uniform Inflow Conditions: A Theoretical and Experimental Approach for Shear Flow

Energy Science &Engineering, EarlyView.
This paper aims to provide a robust design approach for HAWTs operating in shear flow. This study fills a critical research gap by integrating BEM and vortex theories for blade design in non‐homogeneous inflow conditions. The authors of the paper made an effort to develop and test an experimentally unsophisticated model of a turbine working in shear ...

From decision patience to process patience: A decision–process integration of the choice to wait and the experience of waiting

Journal of Consumer Psychology, EarlyView.
Abstract Consumer impatience has long been examined through the lens of intertemporal choice, where patience is inferred from decisions to accept delayed rewards. Yet, this conceptualization captures only the choice to wait, not the experience of waiting.
