Lithium Recovery from Lithium-Ion Battery
Lithium-ion batteries are becoming an integral part of renewable-based energy systems that helps to provide an efficient and greener solution for energy storage. LIBs have found their use in a variety of applications ranging from portable electronic devices to energy grid systems. Owing to the reduction in carbon dioxide emission and improved energy to fuel weight ratio, LIBs have also been widely used in electronic vehicles. LIBs have been especially desirable in this case due to their high charge to mass potential in comparison to other battery types. In the recent decade, the extensive use of LIBs has posed not only a great threat to the world’s lithium resource depletion but also the prevailing problem concerning the consumed and non-recycled LIBs. Hence, immediate attention to alleviate any danger to the ecosystems due to the release of harmful chemicals is required.

Voice-Tacking
Voice-tracking, also called cyber jocking and referred to sometimes colloquially as a robojock, is a technique employed by some radio stations in radio broadcasting to produce the illusion of a live disc jockey or announcer sitting in the radio studios of the station when one is not actually present. It is one of the notable effects of radio homogenization.

Bump Fire
Bump fire is the act of using the recoil of a semi-automatic firearm to fire shots in rapid succession, which simulates the rate of fire of a fully automatic firearm. Bump fire gunstocks are of varying legality in the United States. The Department of Justice announced a plan on March 23, 2018 to classify bump stocks as "machine guns" and effectively ban them nationwide under existing federal law. If the rule becomes final, existing bump stocks would be required to be destroyed or surrendered by both manufacturers and individual owners. On April 17, 2018, Slide Fire Solutions, the sole holder of the bump stock patent, announced that it would cease production of bump stocks as of May 20, though they did not state whether this was a temporary or permanent measure. It has temporarily suspended production before.

List of AEW&C Aircraft Operators
Airborne early warning and control (AEW&C) aircraft are airborne radar systems designed to detect and track aircraft, missiles, ships and vehicles and provide command and control to direct friendly forces. Some operators, such as the Royal Air Force refer to such aircraft as Airborne early warning (AEW), while others reserve the shorter name for AEW aircraft lacking command and control facilities.

Stitched Textile Strain Sensors
By embedding conductive yarns in, or onto, knitted textile fabrics, simple but robust stretch sensor garments can be manufactured. In that way resistance based sensors can be fully integrated in textiles without compromising wearing comfort, stretchiness, washability, and ease of use in daily life. The many studies on such textile strain sensors that have been published in recent years show that these sensors work in principle, but closer inspection reveals that many of them still have severe practical limitations like a too narrow working range, lack of sensitivity, and undesired time-dependent and hysteresis effects. For those that intend to use this technology it is difficult to determine which manufacturing parameters, shape, stitch type, and materials to apply to realize a functional sensor for a given application.

Application of Maturity-Models in Universities
A maturity model is a widely used tool in software engineering and has mostly been extended to domains such as education, health, energy, finance, government, and general use. It is valuable for evaluations and continuous improvement of business processes or certain aspects of organizations, as it represents a more organized and systematic way of doing business.  We present a Systematic Literature Review study of the elements and purposes of the maturity models applied to universities. Obtaining results that show the intention to evaluating the maturity of only some areas of the universities and not the whole, creating some gaps that do not allow to measure the desired level. It also shows how information technologies help its implementation in the field.

Light detection and ranging (LiDAR)
Light Detection and Ranging (LiDAR) is a 3D imaging technique, widely used in many applications such as augmented reality, automotive, machine vision, spacecraft navigation and landing. Achieving long-ranges and high-speed, most of all in outdoor applications with strong solar background illumination, are challenging requirements.

Astrophotography
Astrophotography, also known as astronomical imaging, is the photography or imaging of astronomical objects, celestial events, or areas of the night sky. The first photograph of an astronomical object (the Moon) was taken in 1840, but it was not until the late 19th century that advances in technology allowed for detailed stellar photography. Besides being able to record the details of extended objects such as the Moon, Sun, and planets, modern astrophotography has the ability to image objects invisible to the human eye such as dim stars, nebulae, and galaxies. This is done by long time exposure since both film and digital cameras can accumulate and sum photons over these long periods of time. Photography using extended exposure-times revolutionized the field of professional astronomical research, recording hundreds of thousands of new stars, and nebulae invisible to the human eye. Specialized and ever-larger optical telescopes were constructed as essentially big cameras to record images on photographic plates. Astrophotography had an early role in sky surveys and star classification but over time it has given way to more sophisticated equipment and techniques designed for specific fields of scientific research, with image sensors becoming just one of many forms of sensor. Today, astrophotography is mostly a subdiscipline in amateur astronomy, usually seeking aesthetically pleasing images rather than scientific data. Amateurs use a wide range of special equipment and techniques.
