Communication-Based Control Strategies for Parallel Inverters
The communication-based control methods require a power management platform or supervisory control and data acquisition (SCADA) operation. These control methods are employed to provide power-sharing and voltage control, and their main advantage is eliminating the requirement for a secondary controller. The supervisory control receives information from all inverters and tries to maintain a balance in power-sharing between the inverters.

Biography
Robert Fulton
Robert Fulton (November 14, 1765 – February 25, 1815) was an United States engineer and inventor who is widely credited with developing a commercially successful steamboat; the first was called The North River Steamboat of Clermonts. In 1807 that steamboat traveled on the Hudson River with passengers from New York City to Albany and back again, a round trip of 300 miles, in 62 hours. The succe

Imagery Analysis
Imagery analysis is the extraction of useful information from bi-dimensional graphic formats. This includes color and black-and-white photographs, screen shots, infra-red photographs and video, radar screens and synthetic aperture radar formats, ultrasound, EKG, EEG, MRI, echo cardiograms, seismographs and others. In short, any type of sensor-related data projected in 2- and 3-D formats qualifies as imagery.

Arms Control
Arms control is a term for international restrictions upon the development, production, stockpiling, proliferation and usage of small arms, conventional weapons, and weapons of mass destruction. Arms control is typically exercised through the use of diplomacy which seeks to impose such limitations upon consenting participants through international treaties and agreements, although it may also comprise efforts by a nation or group of nations to enforce limitations upon a non-consenting country.

Artificial Intelligence in the Effective Battery Life Cycle
The rapid growth of battery production and usage will cause waste and disposal-related issues as these batteries reach end-of-life. Moreover, it also causes the depletion of natural mineral resources. Thus, effective battery reuse and recycling procedures are highly important because they contain metals of critical importance. The recycling of batteries causes the return of valuable materials, including lead, lithium, nickel, cadmium, and copper, back to the value chain, partially easing the need to extract new resources. Moreover, recovering metals from batteries reduces the burden on landfills, the burden on the environment, and the negative impact on human health. The critical material’s recirculation also leads to a reduction of the ecological CO2 footprint, which is connected with battery cell production and may provide CO2-neutral battery cell production. Improper battery waste disposal causes harmful effects on human and animal health, as well as the environment, as they contain a huge number of heavy metals. These waste compounds contaminate water, soil, and vegetation.

Coastal Erosion Risks Assessment on Yunlin Coast
A coastal erosion risk assessment was framed as the basis for the intervention of coastal adaptation strategies under time-variant scenarios. The framework was devised to assess the influence of coastal erosion on coastal defense, the coastal inundation induced by the erosion-induced malfunction of defense, and risks using a downscaling analysis and the mechanism of the compound hazard interaction, which are innovative and practical for the application of coastal management in Taiwan.

Flat Panel Display
Flat-panel displays are electronic viewing technologies used to enable people to see content (still images, moving images, text, or other visual material) in a range of entertainment, consumer electronics, personal computer, and mobile devices, and many types of medical, transportation and industrial equipment. They are far lighter and thinner than traditional cathode ray tube (CRT) television sets and video displays and are usually less than 10 centimetres (3.9 in) thick. Flat-panel displays can be divided into two display device categories: volatile and static. Volatile displays require that pixels be periodically electronically refreshed to retain their state (e.g., liquid-crystal displays (LCD)). A volatile display only shows an image when it has battery or AC mains power. Static flat-panel displays rely on materials whose color states are bistable (e.g., e-book reader tablets from Sony), and as such, flat-panel displays retain the text or images on the screen even when the power is off. As of 2016, flat-panel displays have almost completely replaced old CRT displays. In many 2010-era applications, specifically small portable devices such as laptops, mobile phones, smartphones, digital cameras, camcorders, point-and-shoot cameras, and pocket video cameras, any display disadvantages of flat-panels (as compared with CRTs) are made up for by portability advantages (thinness and lightweightness). Most 2010s-era flat-panel displays use LCD and/or LED technologies. Most LCD screens are back-lit as color filters are used to display colors. Flat-panel displays are thin and lightweight and provide better linearity and they are capable of higher resolution than typical consumer-grade TVs from earlier eras. The highest resolution for consumer-grade CRT TVs was 1080i; in contrast, many flat-panels can display 1080p or even 4K resolution. As of 2016, some devices that use flat-panels, such as tablet computers, smartphones and, less commonly, laptops, use touchscreens, a feature that enables users to select onscreen icons or trigger actions (e.g., playing a digital video) by touching the screen. Many touchscreen-enabled devices can display a virtual QWERTY or numeric keyboard on the screen, to enable the user to type words or numbers. A multifunctional monitor (MFM) is a flat-panel display that has additional video inputs (more than a typical LCD monitor) and is designed to be used with a variety of external video sources, such as VGA input, HDMI input from a VHS VCR or video game console and, in some cases, a USB input or card reader for viewing digital photos). In many instances, an MFM also includes a TV tuner, making it similar to a LCD TV that offers computer connectivity.

History of Passive Sliding Base Isolation Systems
Base isolation techniques have emerged as the most effective seismic damage mitigation strategies. Several types of aseismic devices for base isolation have been invented, studied, and used. Out of several isolation systems, sliding isolation systems are popular due to their operational simplicity and ease of manufacturing. These isolators behave passively i.e. their properties of independent of frequency of earthquake excitation. Herein, the historical development of passive sliding isolators based on the number of sliding surfaces is discussed.

Application of RAP in Asphalt Concrete Pavements
The use of recycled asphalt pavement (RAP) materials in asphalt concrete pavements (ACP) brings significant cost and environmental benefits. In practice, however, the amount of RAP readily available far exceeds the amount being utilized in ACPs, which still leaves the problem of excess RAP in the environment partially solved. Additionally, ACPs containing RAP materials (i.e., RAP-ACPs) can still be landfilled after they have reached the end of their useful life, which may restore the original environmental waste problem. To address these, researchers have demonstrated different ways to maximize the application of RAP in ACPs. Among them, the use of RAP in pavement preventive maintenance (PPM) treatments and the repeated recycling of RAP-ACPs (i.e., RnAP) are specifically discussed herein. It is envisaged that, by promoting these two practices, the application and benefits of RAP can be further maximized to improve sustainability.
