Z-Wave is a wireless communication protocol used for Internet of Things (IoT) devices. It is designed to facilitate communication between smart home devices, such as smart locks, thermostats, and light switches, and enable them to be controlled remotely. Z-Wave operates on a low-energy mesh network and uses a frequency band...
“A friend of mine,” said Professor Rackbrane, “has a rectangular garden, and he wants to make exactly one-half of it into a large bed of roses with a gravel path of uniform width around it. Can you find a general rule that will apply equally to any rectangular garden, regardless...
A tape library is a storage device that contains one or more tape drives, a number of slots to hold tape cartridges, a barcode reader to identify tape cartridges, and an automated method for loading tapes. It is also sometimes referred to as a tape silo, tape robot, or tape...
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, 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...
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...
Introduction Mathematics and art have long shared a symbiotic relationship, intertwining to create awe-inspiring and thought-provoking creations. One such fascinating intersection of these disciplines is Tupper’s formula, an intriguing mathematical expression that generates captivating visual patterns. In this article, we delve into the world of Tupper’s formula, exploring its origins,...
In the early 19th century, the world was abuzz with a new form of transportation that would change the way people moved around forever: the velocipede. Also known as the “bone shaker,” the velocipede was a precursor to the modern bicycle and was invented in France in the 1860s. The...
