Optimality vs Completeness: Striking a Balance in Algorithm Design

In computer science, algorithms are essential tools for solving problems efficiently. When designing algorithms, two key concepts to consider are optimality and complexity. Both concepts are related to the efficiency of an algorithm, but they approach efficiency from different perspectives. Optimality refers to the best possible solution to a problem,...

Matrix Factorization

Matrix factorization is an essential technique in linear algebra, which involves decomposing a given matrix into the product of two or more matrices. This technique has numerous applications across various fields, including data analysis, signal processing, machine learning, and computer graphics. Matrix factorization can be understood as a process of...

Building A Power Supply for My DIY CNC Machine

CNC, or Computer Numerical Control, is a revolutionary technology that has transformed the manufacturing industry. CNC machines are used in a wide range of applications, from precision machining to woodworking and metalworking, and have completely changed the way that many products are manufactured. CNC machines are essentially automated tools that...

Vim vs NeoVim

Vim and NeoVim are both powerful and popular text editors that are widely used in the software development community. Both editors are based on the original Vi editor, which was developed in the 1970s and is still widely used today. Vim is a free and open-source text editor that is...

What is Linear Algebra?

Linear algebra is a branch of mathematics that deals with linear equations, linear transformations, and vector spaces. It plays an important role in various fields, including physics, engineering, computer science, and economics. At its core, linear algebra studies the properties of linear equations and linear systems of equations, which are...

The Mercury Delay Line Memory

The mercury delay line was a method for representing binary zeros and ones as pulses of acoustic energy that relied on sound waves flowing through a tube of mercury. At the very least, in principle, the pulses could travel through the delay line unbrokenly if they were to capture the...

Magnetic-core Memory

Magnetic-core memory, also known as core memory or ferrite core memory, was one of the first types of random access memory (RAM) used in computers. It was developed in the late 1940s and remained in use until the 1970s. Core memory was important because it allowed computers to store data...

Miniature Untethered EEG Recorder Improves
Advanced Neuroscience Methodologies

The NAT-1 (Neural Activity Tracker) is a highly miniaturised wireless electronic recording system created in an industry-academic collaboration by the Universities of York, Aberdeen, and Cybula Ltd., with specific applications in rodent-based neuroscience. In preclinical research, rodent electroencephalography (EEG) is often used in acting animals. The difficulty in distinguishing EEG...
