Rolling display using Matrix LEDs

Abstract:
This project can be used for Advertising or for providing information at various places like shops, government offices, hospitals, railway stations. The Rolling display is prepared using 5 X 7 Matrix LEDs which means LEDs are arranged in a pattern consisting of 5 columns and 7 rows. A matrix of 5 X 7 LEDs contribute to a single character. Here we have used 6 characters which means 6 matrices. The actual physical diamension of single matrix is 10 cm by 8 cm, so diamension of complete displa ....etc

Abstract Deriving the proper density to achieve the region coverage for random sensors deployment is a fundamentally important problem in the area of wireless sensor networks. Most existing works on sensor coverage mainly concentrate on the two-dimensional (2D) plane coverage which assume that all the sensors are deployed on an ideal plane. In contrast, sensors are also deployed on the three-dimensional (3D) rolling surfaces in many real applications. Toward this end, we study the coverage problem of wireless sensor networks for the rolling te ....etc

Introduction to CWR

The CWR is a rotary forming process, consists
of the forming of forging by means of wedge-shaped tools that are fixed on the mill rolls with the same rotary direction.
In CWR process, there are five stages in the work piece deformation process corresponding to five zones of the wedged tool geometry, i.e., knifing, guiding, stretching, shaping, and sizing.

Knifing zone, is ....etc

A rolling machine is a machine that is designed to roll either tobacco, cannabis, or other products such as synthetic cannabis into individual cigarettes or joints. To roll a cigarette with cannabis, one must break up the smoking material, which can be done using a grinder, as well as remove any stems so they won't puncture the paper. Rolling a cigarette with tobacco does not require prep work because the leaf is already shredded.
Once the material is ready, one opens up the rolling machine by sliding one of the rollers up and over; this expose ....etc
