Abstract: Facial recognition technology now days is used to identify or verify individuals based on their facial features. It works by analysing key facial landmarks and comparing them with a stored ...

I will start thinking about point control and power supply for the new track layout. First, I will use Electrofrog points for the main line and equivalent tracks. The most important reason is that ...

Since the dawn of computers, we’ve tried different ways to store data. These days, you grab data over the network, but you probably remember using optical disks, floppies, or, more recently, flash ...

Abstract: This research study presents the design and execution of a dual battery system, regenerative energy generation, and self-charging electronic bicycle (e-bike). A 12-volt generating motor is ...

The following project is an update of Gary D. Patterson’s “Simplified CTC signals” in the July 1988 issue of MR. Bringing the project up to date was a large endeavour. The block control project now ...

A well and water tank level controller is intended to work in harsh conditions, particularly in environments not always suitable for sensitive electronics. The wired-logic controller proposed here is ...
