Widely known as carputer, this system is designed for:
* calculating speed, fuel consumption, economy driving, e.t.c.
* displaying information about temperatures and controll Air Conditioning system in your car.*
* controlling other devices, like electrically opened windows.*
The system is based on ATMega MCU programmed in C language.
This version of the book is a DRAFT! The chapters are mostly complete, but not carefully edited. Some of the debugging sections are not done, and not all chapters have exercises.

The goal of our final project was to design an efficient elevator simulator that can accept input from a user and mechanically operate (on a small scale) a system of 4 floors and 3 elevators using pulleys and stepper motors. Users enter input using physical pushbuttons or the computer. This input is then processed by the MCU and orders are given to the elevators. We attempted to devise an algorithm that can optimally handle any number of floors. This project seemed like a fun challenge and something that had practical applications. Both of us have been frustrated at times by the inefficiency of some of the elevators here at Cornell, and we wanted to see if we could do a better job.
This book is for all those people.
• For the person who thinks programming is too hard
• For the person who gets bogged down when writing or changing
larger scripts (our analyst)
• For the person who knows the wrong languages well (our programmer):
languages like Java, C#, C++, and C are perfectly fine
languages—in their niche.
The Rails Cookbook is is packed with the solutions you need to be a proficient developer with Rails, the leading framework for building the new generation of Web 2.0 applications. Recipes range from the basics, like installing Rails and setting up your development environment, to the latest techniques, such as developing RESTful web services.
Topics include:
. Modeling data with the ActiveRecord library
. Setting up views with ActionView and RHTML templates
. Building your application s logic into ActionController
. Testing and debugging your Rails application
. Building responsive web applications using JavaScript and Ajax
. Ensuring that your application is security and performs well

Channel transmission simulator
Channel transmission simulator
％
％ inputs:
％ sig2 - noise variance
％ Mt - number of Tx antennas
％ Mr - number of Rx antennas
％ x - vector of complex input symbols (for MIMO, this is a matrix, where each column
％ is the value of the antenna outputs at a single time instance)
％ H - frequency selective channel - represented in block-Toeplitz form for MIMO transmission
％ N - number of symbols transmitted in OFDM frame
％
％ outputs:
％ y - vector of channel outputs (matrix for MIMO again, just like x matrix)
％ create noise vector sequence (each row is a different antenna, each column is a
％ different time index) note: noise is spatially and temporally white
A very smaller script interpretor that java based system. Can work on j2se / j2me / win C++ platform ,the major goal is used to build more flexible j2me game. Script language s phrase like as BASIC .
Object-oriented languages
define objects (types of things) that know how to perform methods (specific actions).
Functional languages treat programming problems like mathematical relationships.
Ruby is flexible, meaning that you can program in any of these styles however, it is
primarily object oriented, with some strong functional influence. This book focuses
slightly more on the functional aspects of Ruby than some other books.
