Seductive Details
Seductive details are often used in textbooks, lectures, slideshows, and other forms of educational content to make a course more interesting or interactive. Seductive details can take the form of text, animations, photos, illustrations, sounds or music and are by definition: (1) interesting and (2) not directed toward the learning objectives of a lesson. John Dewey, in 1913, first referred to this as “fictitious inducements to attention.” While illustrated text can enhance comprehension, illustrations that are not relevant can lead to poor learning outcomes. Since the late 1980s, many studies in the field of educational psychology have shown that the addition of seductive details results in poorer retention of information and transfer of learning. Thalheimer conducted a meta-analysis that found, overall, a negative impact for the inclusion of seductive details such as text, photos or illustrations, and sounds or music in learning content. More recently, a 2020 paper found a similar effect for decorative animations This reduction to learning is called the seductive details effect. There have been criticisms of this theory. Critics cite unconvincing and contradictory evidence to argue that seductive details do not always impede understanding and that seductive details can sometimes be motivating for learners.

GPS-aided GEO Augmented Navigation
The GPS-aided GEO augmented navigation (GAGAN) is an implementation of a regional satellite-based augmentation system (SBAS) by the Government of India. It is a system to improve the accuracy of a GNSS receiver by providing reference signals. The AAI's efforts towards implementation of operational SBAS can be viewed as the first step towards introduction of modern Communication, navigation and surveillance/Air Traffic Management system over Indian airspace. The project has established 15 Indian reference stations, 3 Indian navigation land uplink stations, 3 Indian mission control centers, and installation of all associated software and communication links. It will be able to help pilots to navigate in the Indian airspace by an accuracy of 3 m. This will be helpful for landing aircraft in marginal weather and difficult approaches like Mangalore and Leh airports.

Unmanned Spaceflights to the International Space Station
Uncrewed spaceflights to the International Space Station (ISS) are made primarily to deliver cargo, however several Russian modules have also docked to the outpost following uncrewed launches. Resupply missions typically use the Russian Progress spacecraft, European Automated Transfer Vehicles, Japanese Kounotori vehicles, and the American Dragon and Cygnus spacecraft. The primary docking system for Progress spacecraft is the automated Kurs system, with the manual TORU system as a backup. ATVs also use Kurs, however they are not equipped with TORU. Progress and ATV can remain docked for up to six months. The other spacecraft — the Japanese HTV, the SpaceX Dragon and the Orbital Sciences Cygnus — rendezvous with the station before being grappled using Canadarm2 and berthed at the nadir port of the Harmony or Unity module for one to two months. As of September 2018, Progress spacecraft have flown most of the uncrewed missions to the ISS.

Meunier Rifle
The Meunier rifle, known as the "Meunier A6" or "STA No. 8", evolved as a part of the program initiated in 1890 by the French military to develop a semi-automatic infantry rifle that would eventually replace the Mle 1886-93 Lebel rifle. Four government research establishments (STA, ENT, Puteaux and CTV) proposed over 20 prototypes. About half of them were based on recoil (both short recoil and long recoil) and the others were gas operated. This secret program was placed under the direction of General Naquet-Laroque who headed the Puteaux (APX) government arsenal.

Cyber–Physical Systems Forensics
Cyber–Physical Systems (CPS) connect the physical world (systems, environments, and humans) with the cyber world (software, data, etc.) to intelligently enhance the operational environment they serve. CPS are distributed software and hardware components embedded in the physical world and possibly attached to humans. CPS are vulnerable to security risks, which requires incorporating appropriate forensics measures in the design and operations of these systems.
