Clean IT Project
The Clean IT Project is an online project initiated by the European Union, aiming to reduce or discourage online terrorism and further illegal activities via the internet. They aim to create a document that commits the internet industry to help governments discover content that incites acts of terrorism. The main facilitators that undertook this project were the Netherlands, Germany, United Kingdom, Belgium, and Spain. There are many more supporting EU members such as Hungary, Romania, and recently, Italy, but the main countries that have started the project are the 5 listed above.

IBM System Object Model
In computing, the System Object Model (SOM) is an object-oriented shared library system developed by IBM. DSOM, a distributed version based on CORBA, allowed objects on different computers to communicate. SOM defines an interface between programs, or between libraries and programs, so that an object's interface is separated from its implementation. SOM allows classes of objects to be defined in one programming language and used in another, and it allows libraries of such classes to be updated without requiring client code to be recompiled. A SOM library consists of a set of classes, methods, static functions, and data members. Programs that use a SOM library can create objects of the types defined in the library, use the methods defined for an object type, and derive subclasses from SOM classes, even if the language of the program accessing the SOM library does not support class typing. A SOM library and the programs that use objects and methods of that library need not be written in the same programming language. SOM also minimizes the impact of revisions to libraries. If a SOM library is changed to add new classes or methods, or to change the internal implementation of classes or methods, one can still run a program that uses that library without recompiling. This is not the case for all other C++ libraries, which in some cases require recompiling all programs that use them whenever the libraries are changed, known as the fragile binary interface problem. SOM provides an application programming interface (API) that gives programs access to information about a SOM class or SOM object. Any SOM class inherits a set of virtual methods that can be used, for example, to find the class name of an object, or to determine whether a given method is available for an object.

Reduction (Complexity)
In computability theory and computational complexity theory, a reduction is an algorithm for transforming one problem into another problem. A reduction from one problem to another may be used to show that the second problem is at least as difficult as the first. Intuitively, problem A is reducible to problem B if an algorithm for solving problem B efficiently (if it existed) could also be used as a subroutine to solve problem A efficiently. When this is true, solving A cannot be harder than solving B. "Harder" means having a higher estimate of the required computational resources in a given context (e.g., higher time complexity, greater memory requirement, expensive need for extra hardware processor cores for a parallel solution compared to a single-threaded solution, etc.). We write A ≤m B, usually with a subscript on the ≤ to indicate the type of reduction being used (m : mapping reduction, p : polynomial reduction). The mathematical structure generated on a set of problems by the reductions of a particular type generally forms a preorder, whose equivalence classes may be used to define degrees of unsolvability and complexity classes.

BioMA
Modelling frameworks are used in modelling and simulation and can consist of a software infrastructure to develop and run mathematical models. They have provided a substantial step forward in the area of biophysical modelling with respect to monolithic implementations. The separation of algorithms from data, the reusability of I/O procedures and integration services, and the isolation of modelling solutions in discrete units has brought a solid advantage in the development of simulation systems. Modelling frameworks for agriculture have evolved over time, with different approaches and targets BioMA is a software framework developed focusing on platform-independent, re-usable components, including multi-model implementations at fine granularity.

Seagate Barracuda
The Seagate Barracuda is a series of hard disk drives and later solid state drives produced by Seagate Technology that was first introduced in 1993. The line initially focused on high-capacity, high-performance SCSI hard drives until introducing ATA models in 1999 and SATA models in 2002. Since 2001, the Barracuda is Seagate's most popular product line as the hard disk drive industry started to move to a 7200 RPM spindle speed.

Fallout Shelter (Video Game)
Fallout Shelter is a free-to-play simulation video game developed by Bethesda Game Studios, with assistance by Behaviour Interactive, and published by Bethesda Softworks. Part of the Fallout series, it was released worldwide for iOS devices in June 2015, for Android devices in August 2015, for Microsoft Windows in July 2016, Xbox One in February 2017, and PlayStation 4 and Nintendo Switch in June 2018. The game is also available on Tesla vehicles. The game tasks the player with building and effectively managing their own Vault, a fallout shelter. Upon release, Fallout Shelter received mostly positive reviews. Critics enjoyed the game's extension of the Fallout universe, the core gameplay, and its visual style. Common criticisms included the game's lack of depth, its use of unnecessary microtransactions, and its lack of an ending. The game grossed US$5.1 million (equivalent to about $5.5M in 2019) in microtransaction sales in the first two weeks after its release. While Fallout Shelter is a single-player experience, a multiplayer board game adaptation of the game was released about five years after its original release.

Konqi
Konqi is the mascot of KDE. He is a cheerful green cartoon dragon. He was first introduced In April 1999, as the new animated assistant of KDE Help Center and later became KDE's mascot in version 3.x. Recognized as part of the KDE community's identity, he appears in KDE software's about dialogue, printed materials, conference presentations, as well as on many of KDE's websites. His former version was designed by Stefan Spatz and the current version was designed by Tyson Tan.

Lazarus (IDE)
Lazarus is a free cross-platform visual integrated development environment (IDE) for rapid application development (RAD) using the Free Pascal compiler. Its goal is to provide an easy-to-use development environment for programmers developing with the Pascal Object language, which is as close as possible to Delphi. Software developers use Lazarus to create native-code console and graphical user interface (GUI) applications for the desktop, and also for mobile devices, web applications, web services, visual components and function libraries for a number of different platforms, including Mac, Linux and Windows. An application created using Lazarus on one platform can generally compile and execute on any platform for which a Free Pascal compiler exists. For desktop applications a single source can target Mac, Linux, and Windows, with little or no modification. An example is the Lazarus IDE itself, created from a single code base and available on all major platforms including the Raspberry Pi.

Drone Network-Based Disaster Recovery
Communication establishment is crucial for rescue operations in disaster affected areas. A standard tool for communication is the use of cell phones. However, they can be useless in situations where the cellular network’s base stations are damaged in a disaster. A contemporary approach to re-establishing a communication network is by hosting base stations in drones.

Application of Triboelectric Nanogenerator in Fluid Dynamics Sensing
The triboelectric nanogenerator (TENG) developed by Z. L. Wang’s team to harvest random mechanical energy is a promising new energy source for distributed sensing systems in the new era of the internet of things (IoT) and artificial intelligence (AI) for a smart world. In industry and academia, fluid dynamics sensing for liquid and air is urgently needed but lacking. In particular, local fluid sensing is difficult and limited to traditional sensors. Fortunately, with advantages for ordinary TENGs and TENGs as fluid dynamics sensors, fluid dynamics sensing can be better realized.
