The Parvaresh–Vardy code is a type of error-correcting code that was introduced by the researchers Mohammad Parvaresh and Alexander Vardy in their work on coding theory. This code is specifically designed to correct errors in a way that is particularly efficient for communication over noisy channels. The Parvaresh–Vardy code is notable for its ability to correct a large number of errors while maintaining relatively low complexity in terms of the encoding and decoding processes.

D* (pronounced "D-star") is a dynamic pathfinding algorithm used in robotics and artificial intelligence for real-time path planning in environments where obstacles may change over time. It is particularly useful in situations where a robot needs to navigate through a space that may have shifting or unknown obstacles. D* was originally developed for applications in mobile robotics, allowing a robot to efficiently update its path as the environment changes.

Slepian–Wolf coding is a concept from information theory that refers to a method for compressing correlated data sources. It addresses the problem of lossless data compression for distinct but correlated sources when encoding them separately. Named after David Slepian and Jack Wolf, who introduced the concept in their 1973 paper, Slepian-Wolf coding demonstrates that two or more sources of data can be compressed independently while still achieving optimal overall compression when the dependencies between the sources are known.

Triple Modular Redundancy (TMR) is a fault-tolerant technique used in digital systems, particularly in safety-critical applications like aerospace, automotive, and industrial control systems. The fundamental idea behind TMR is to enhance the reliability of a computing system by using three identical modules (or systems) that perform the same computations simultaneously. Here's how TMR typically works: 1. **Triple Configuration**: The system is configured with three identical units (modules).

Zigzag code, also known as zigzag encoding, is a technique used primarily in data compression and error correction, particularly in contexts like run-length encoding or within certain video and image compression standards such as JPEG encoding. The main concept of zigzag coding is to traverse a two-dimensional array (like an 8x8 block of pixels in an image) in a zigzag manner, rather than in a row-major or column-major order.

Funnelsort is a comparison-based sorting algorithm that uses a data structure called a "funnel" to sort a list of elements. It is notable for its efficiency in certain scenarios, particularly when dealing with large datasets. ### Key Features of Funnelsort: 1. **Funnel Data Structure**: The algorithm utilizes a funnel, which can conceptually be thought of as a series of channels that direct incoming elements based on comparisons. The funnel structure allows the algorithm to efficiently merge elements as they are processed.

Cyclotomic Fast Fourier Transform (CFFT) is a specialized algorithm for efficiently computing the Fourier transform of sequences, particularly those with lengths that are power of a prime, like \( p^n \) where \( p \) is a prime number. CFFT leverages the properties of cyclotomic fields and roots of unity to achieve fast computation similar to traditional Fast Fourier Transform (FFT) algorithms but with optimizations that apply to the specific structure of cyclotomic polynomials.

The Prime-factor Fast Fourier Transform (PFFFT) is an efficient algorithm used for computing the Discrete Fourier Transform (DFT) of a sequence. It is particularly useful when the length of the input sequence can be factored into two or more relatively prime integers. The PFFFT algorithm takes advantage of the mathematical properties of the DFT to reduce the computational complexity compared to a naive computation of the DFT.

The Split-Radix FFT (Fast Fourier Transform) algorithm is a mathematical technique used to compute the discrete Fourier transform (DFT) and its inverse efficiently. It is an optimization of the FFT algorithm that reduces the number of arithmetic operations required, making it faster than the traditional Cooley-Tukey FFT algorithm in certain scenarios.

The term "twiddle factor" typically appears in the context of the Fast Fourier Transform (FFT) algorithm, which is used for efficiently computing the discrete Fourier transform (DFT) and its inverse. In FFT implementations, especially the Cooley-Tukey algorithm, twiddle factors are complex exponential terms that are used to facilitate the mixing of the input data at different stages of the algorithm.

BpsA, also known as biofilm polysaccharide A, is a polysaccharide that is produced by certain bacteria, particularly Pseudomonas aeruginosa. It is part of the extracellular matrix that contributes to the biofilm formation by these bacteria. Biofilms are complex communities of microorganisms that adhere to surfaces and are surrounded by a self-produced protective matrix, which can include polysaccharides, proteins, and other materials.

Proportional-fair scheduling is an algorithm used primarily in wireless communication networks to allocate resources among multiple users in a way that balances fairness and efficiency. The concept was introduced to solve the challenges associated with allocating limited bandwidth among users competing for access to a network resource. ### Key Characteristics: 1. **Fairness**: The goal of proportional-fair scheduling is to ensure that users are served in a manner that is fair relative to each other.

Canvas fingerprinting is a technique used for tracking and identifying users online based on the unique characteristics of their web browsers and devices. It is part of a broader category known as "browser fingerprinting," which aims to collect various data points to create a unique identifier for a user without the use of cookies. Here's how canvas fingerprinting typically works: 1. **Canvas Element**: This method utilizes the HTML5 `` element, which allows for the rendering of graphics and text in web browsers.

In computing, "fingerprint" typically refers to a unique identifier that is used to recognize or authenticate a device, user, or data. The concept of fingerprinting can take several forms, depending on the context: 1. **User Fingerprinting**: This involves creating a unique identifier for individual users based on various attributes or behaviors.

The Rabin fingerprint is a technique used for quickly computing a compact representation (or "fingerprint") of a string or a sequence of data, which can then be used for various purposes such as efficient comparison, searching, and data integrity verification. It is particularly useful in applications like plagiarism detection, data deduplication, and network protocols.

The Algorithmic Justice League (AJL) is an organization focused on combating bias in artificial intelligence (AI) and advocating for fair and accountable technology. Founded by Joy Buolamwini, a researcher and activist, AJL aims to raise awareness of the ways in which algorithms can perpetuate social inequalities and discriminate against marginalized groups. The organization conducts research, develops tools, and engages in advocacy to promote transparency and accountability in AI systems.

Artificial Intelligence (AI) in government refers to the application of AI technologies and techniques to enhance public services, improve governance, and support decision-making processes within government entities. The integration of AI can lead to more efficient operations, better data analysis, improved service delivery, and a more informed and responsive government.

The electronic process of law in Brazil, known as "Processo Eletrônico," refers to the digitalization of legal procedures and documentation in the Brazilian judicial system. This initiative aims to streamline judicial processes, enhance efficiency, reduce paperwork, and improve access to justice. Here are some key aspects of the electronic process of law in Brazil: 1. **Digital Procedures**: Legal documents are submitted electronically, allowing for online filing of lawsuits, motions, and other judicial documents.

The "Gangs Matrix" typically refers to a controversial policing tool used primarily in the United States, particularly in Chicago, to identify and monitor individuals who are believed to be involved in gang activity. The matrix categorizes individuals based on various criteria, including their alleged gang affiliations, criminal history, and interactions with law enforcement. The purpose of the Gangs Matrix is to facilitate targeted policing efforts and resource allocation by identifying potential gang members and their activities.
