TL;DR: A complete pansharpening scheme based on the use of morphological half gradient operators is designed and the suitability of this algorithm is demonstrated through the comparison with the state-of-the-art approaches.
Abstract: Nonlinear decomposition schemes constitute an alternative to classical approaches for facing the problem of data fusion. In this paper, we discuss the application of this methodology to a popular remote sensing application called pansharpening, which consists in the fusion of a low resolution multispectral image and a high-resolution panchromatic image. We design a complete pansharpening scheme based on the use of morphological half gradient operators and demonstrate the suitability of this algorithm through the comparison with the state-of-the-art approaches. Four data sets acquired by the Pleiades, Worldview-2, Ikonos, and Geoeye-1 satellites are employed for the performance assessment, testifying the effectiveness of the proposed approach in producing top-class images with a setting independent of the specific sensor.

TL;DR: In this paper, a centralized protection strategy for medium voltage dc microgrids is presented, which consists of a communication-assisted fault detection method with a centralized coordinator and a fault isolation technique that provides an economic, fast, and selective protection by using the minimum number of dc circuit breakers.
Abstract: This paper presents a centralized protection strategy for medium voltage dc microgrids. The proposed strategy consists of a communication-assisted fault detection method with a centralized protection coordinator and a fault isolation technique that provides an economic, fast, and selective protection by using the minimum number of dc circuit breakers. The proposed method is also supported by a backup protection that is activated if communication fails. This paper also introduces a centralized self-healing strategy that guarantees successful operation of zones that are separated from the main grid after the operation of the protection devices. Furthermore, to provide a more reliable protection, thresholds of the protection devices are adapted according to the operational modes of the microgrid and the status of distributed generators. The effectiveness of the proposed protection strategy is validated through real-time simulation studies based on the hardware in the loop approach.

TL;DR: In this article, a new bulk glassy alloy (BGA) showing macroscopic tensile plastic elongation at room temperature has been developed in the hypoeutectic Zr-Ni-Cu-Al alloy system.
Abstract: A new bulk glassy alloy (BGA) showing macroscopic tensile plastic elongation at room temperature has been developed in the hypoeutectic Zr–Ni–Cu–Al alloy system. The hypoeutectic Zr–Ni–Cu–Al BGA shows a high Poisson's ratio, a low Young's modulus, and is highly malleable in compression. It exhibits a Poisson's ratio of 0.39, a Young's modulus of 73 GPa, and a distinct tensile plastic elongation of about 1.7% at room temperature with necking due to the operation of many shear bands. The tensile plastic deformability seems to originate from modifications of the glass structure with increasing the number of Zr–Zr atomic pairs in the hypoeutectic composition.

TL;DR: In this paper, the authors describe the design and fabrication of electrically controlled paper actuators that operate based on the dimensional changes that occur in paper when the moisture absorbed on the surface of the cellulose fi bers changes.
Abstract: This paper describes the design and fabrication of electrically controlled paper
actuators that operate based on the dimensional changes that occur in paper
when the moisture absorbed on the surface of the cellulose fi bers changes.
These actuators are called “Hygroexpansive Electrothermal Paper Actuators”
(HEPAs). The actuators are made from paper, conducting polymer, and
adhesive tape. They are lightweight, inexpensive, and can be fabricated using
simple printing techniques. The central element of the HEPAs is a porous
conducting path (used to provide electrothermal heating) that changes the
moisture content of the paper and causes actuation. This conducting path
is made by embedding a conducting polymer (PEDOT:PSS) within the paper,
and thus making a paper/polymer composite that retains the porosity and
hydrophilicity of paper. Different types of HEPAs (straight, precurved, and
creased) achieved different types of motions (e.g., bending motion, accordion
type motion). A theoretical model for their behavior is proposed. These actuators
have been used for the manipulation of liquids and for the fabrication of
an optical shutter.
