Introduction
An elevator is a device designed as a convenience appliance that has evolved to become an unavoidable feature of modern day urban life. The Oxford Dictionary defines an elevator as, “A machine that carries people or goods up and down to different levels in a building or mine”. While a standalone elevator is a simple electro-mechanical device, an elevator system may consist of multiple standalone elevator units whose operations are controlled and coordinated by a master controller. S ....etc

SPACE ELEVATOR A NANO DREAM


THE Concept

A 35000-mile long cable
will hang in space, stationary and tight !
CentripetAl force
The space elevator is a cable that can be ascended from Earth to space, with one end fixed on earth.


Build in a similar way to how difficult bridges were built in the past. In building a bridge, the first thing that was done was a small string was thrown or shot across a canyon. Then a larger string is attached to this first small string and pulled across.

Elevator Controller Implementation
Presented By
Abhishek Gupta Varun Aggarwala
Under the guidance of Dr. J.K Deka

Problem statement:

To design an Elevator controller for any number of floors.
Algorithm:

There are different algorithms that could be used for designing the elevator controller. The important one's are:

1. elevator algorithm::
Serve the entire request in one direction and then reverse the direction.
2. shortest seek first
Serve the request closest to the present floor
3. first come fi ....etc

Introduction
Hydraulic elevator
Cable system elevator
The most popular elevator design is the roped elevator. In roped elevators, the car is raised and lowered by traction steel ropes rather than pushed from below.
­ ­ The ropes are attached to the elevator car, and looped around a sheave . A sheave is just a pulley with a grooves around the circumference. The sheave grips th­e hoist ropes, so when you rotate the sheave, the ropes move too.
The sheave is connected to an electric motor . When the motor turns on ....etc

Hydraulic elevator systems lift weights using a hydraulic ram, a fluid-driven piston mounted inside a cylinder. The cylinder is connected to a fluid-pumping system (typically, hydraulic systems like use oil, but other incompressible fluids would also work). The hydraulic system has three parts:
A tank (the fluid reservoir)
A pump, powered by an electric motor
A valve between the cylinder and the reservoir
The pump forces fluid from the tank into a pipe leading to the cylinder. When the valve is opened, the pressurized fluid will take ....etc

The Elevator Lab


This lab will lead you through slightly more advanced topics of the Bluespec System Verilog language and the usage of the Bluespec compiler, Bluesim simulator and the Bluespec development workstation. In each part you will find a description of the actual code you will have to generate and how to use and invoke each of the previously mentioned tools.
Note 1: The directory $BLUESPECDIR/../doc/BSV contains very useful documentation that ....etc

Experts agree that the biggest drain of energy takes place when a vehicle blasts off, pushing through Earth?s gravitational pull requires great amounts of fuel, but once they get out of our atmosphere, the rest is easy.

If you could cut out that ?blast off? portion, space travel would be easier and much more fuel-efficient.

In a Space Elevator scenario, a Maglev vehicle would zoom up the side of an exceedingly tall structure and end up at a transfer point where they?d then board a craft to the Moon, Mars, or any other distant destination ....etc
