English on EU Countries' Websites
The English language is the most dominant language in the western world and its influence can be noticed in every aspect of human communication. This article presents data about the prevalence of the English language in the different countries and regions of the European Union. By analyzing and processing the findings from over 100000 websites from every country in the EU, a solid foundation is set that is used to explore the dominance of the English language in the European World Wide Web in general. The results of this process demonstrate that the English language is not only available on more than one quarter of all websites of non-English speaking EU countries, but is also available in the vast majority of multilingual and bilingual websites of the EU, while at the same time being the only available language in a number of monolingual websites and shown preference over the national language in a significant number of cases.

Radix-16 Floating Point
IBM hexadecimal floating point is number representation. IBM System/360 computers, and subsequent machines based on that architecture (mainframes), support a hexadecimal floating-point format (HFP). In comparison to IEEE 754 floating-point, the IBM floating-point format has a longer significand, and a shorter exponent. All IBM floating-point formats have 7 bits of exponent with a bias of 64. The normalized range of representable numbers is from 16−65 to 1663 (approx. 5.39761 × 10−79 to 7.237005 × 1075). The number is represented as the following formula: (−1)sign × 0.significand × 16exponent−64.

Noise Removal Filter for LiDAR Point Clouds
Light Detection and Ranging (LiDAR) is a critical sensor for autonomous vehicle systems, providing high-resolution distance measurements in real-time. However, adverse weather conditions such as snow, rain, fog, and sun glare can affect LiDAR performance, requiring data preprocessing.

Data Link in IoT WSNs
The Internet of things (IoT) and wireless sensor networks (WSNs) have been rapidly and tremendously developing recently as computing technologies have brought about a significant revolution. Their applications and implementations can be found all around us, either individually or collaboratively. WSN plays a leading role in developing the general flexibility of industrial resources in terms of increasing productivity in the IoT. The critical principle of the IoT is to make existing businesses sufficiently intelligent to recognize the need for significant fault mitigation and short-cycle adaptation to improve effectiveness and financial profits.

Binary Adder
An adder, or summer, is a digital circuit that performs addition of numbers. In many computers and other kinds of processors adders are used in the arithmetic logic units (ALUs). They are also used in other parts of the processor, where they are used to calculate addresses, table indices, increment and decrement operators and similar operations. Although adders can be constructed for many number representations, such as binary-coded decimal or excess-3, the most common adders operate on binary numbers. In cases where two's complement or ones' complement is being used to represent negative numbers, it is trivial to modify an adder into an adder–subtractor. Other signed number representations require more logic around the basic adder.

Leela Chess Zero
Leela Chess Zero (abbreviated as LCZero, lc0) is a free, open-source, and deep neural network–based chess engine and distributed computing project. Development has been spearheaded by programmer Gary Linscott, who is also a developer for the Stockfish chess engine. Leela Chess Zero was adapted from the Leela Zero Go engine, which in turn was based on Google's AlphaGo Zero project. One of the purposes of Leela Chess Zero was to verify the methods in the AlphaZero paper as applied to the game of chess. Like Leela Zero and AlphaGo Zero, Leela Chess Zero starts with no intrinsic chess-specific knowledge other than the basic rules of the game. Leela Chess Zero then learns how to play chess by reinforcement learning from repeated self-play, using a distributed computing network coordinated at the Leela Chess Zero website. (As of January 2022), Leela Chess Zero has played over 500 million games against itself, playing around 1 million games every day, and is capable of play at a level that is comparable with Stockfish, the leading conventional chess program.

Long and Short Scale
The long and short scales are two of several naming systems for integer powers of ten which use some of the same terms for different magnitudes. For whole numbers smaller than 1,000,000,000 (109), such as one thousand or one million, the two scales are identical. For larger numbers, starting with 109, the two systems differ. For identical names, the long scale proceeds by powers of one million, whereas the short scale proceeds by powers of one thousand. For example, "one billion" means one thousand millions in the short scale, while it means one million millions in the long scale. The long scale system uses additional terms for the intervening values, typically replacing the word ending -ion with -iard.

FileMaker Pro
FileMaker Pro is a cross-platform relational database application from Claris International, a subsidiary of Apple Inc. It integrates a database engine with a graphical user interface (GUI) and security features, allowing users to modify the database by dragging new elements into layouts, screens, or forms. FileMaker evolved from a DOS application, but was then developed primarily for the Apple Macintosh and released in April 1985. It was succeeded by FileMaker Pro in 1990. Since 1992 it has been available for Microsoft Windows and for the classic Mac OS and macOS, and can be used in a cross-platform environment. FileMaker server briefly ran on Linux, but Linux support was abandoned with FileMaker 7, thereafter only running on Windows or macOS servers. A client version was released for iOS devices in July 2010. It is available in desktop, server, iOS and web-delivery configurations. In 2016, FileMaker Cloud was introduced, including a Linux server (CentOS), which was offered exclusively through the Amazon Marketplace. In November 2019, FileMaker Cloud was reintroduced as a software as a service product offered directly from Claris for FileMaker Pro 18.0.3 using FileMaker Server Cloud 2.18 service on Amazon Servers, but managed by Claris instead of through the Amazon Market Place, and making use of the new FileMaker ID authentication.

Statistical Analysis of Intensive Care Unit COVID-19 Data
COVID-19 caused a pandemic, due to its ease of transmission and high number of infections. The evolution of the pandemic and its consequences for the mortality and morbidity of populations, especially the elderly, generated several scientific studies and many research projects. Among them, researchers have the Predictive Models of COVID-19 Outcomes for Higher Risk Patients Towards a Precision Medicine (PREMO) research project. For such a project with many data records, it is necessary to provide a smooth graphical analysis to extract value from it.

Data Transmission
Data transmission (also data communication or digital communications) is the transfer of data (a digital bitstream or a digitized analog signal) over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires, optical fibers, wireless communication channels, storage media and computer buses. The data are represented as an electromagnetic signal, such as an electrical voltage, radiowave, microwave, or infrared signal. Analog or analogue transmission is a transmission method of conveying voice, data, image, signal or video information using a continuous signal which varies in amplitude, phase, or some other property in proportion to that of a variable. The messages are either represented by a sequence of pulses by means of a line code (baseband transmission), or by a limited set of continuously varying waveforms (passband transmission), using a digital modulation method. The passband modulation and corresponding demodulation (also known as detection) is carried out by modem equipment. According to the most common definition of digital signal, both baseband and passband signals representing bit-streams are considered as digital transmission, while an alternative definition only considers the baseband signal as digital, and passband transmission of digital data as a form of digital-to-analog conversion. Data transmitted may be digital messages originating from a data source, for example a computer or a keyboard. It may also be an analog signal such as a phone call or a video signal, digitized into a bit-stream, for example, using pulse-code modulation (PCM) or more advanced source coding (analog-to-digital conversion and data compression) schemes. This source coding and decoding is carried out by codec equipment.
