WISENET is a wireless sensor network that monitors the environmental conditions such as light, temperature, and humidity. This network is comprised of nodes called motes that form an ad-hoc network to transmit this data to a computer that function as a server.

The server stores the data in a database where it can later be retrieved and analyzed via a web-based interface. The network works successfully with an implementation of one sensor mote. ....etc

SEMINAR REPORT ON YBERNETICS
ABSTRACT
As first defined by Norbert Wiener Cybernetic is the Control and communication in the animal and the machine. The principles of cybernetics have been applied in many fields. The errands of cybernetics application are including the extending of application domain, subdividing the problem, and building of reliability features, dealing of parallel and concurrent computation, handling of error states, and creating of precision requirements. This paper gives the small overview of cybern ....etc

Introduction

In digital communication , CellonicsTM offers a fundamental change to the way modem solutions have traditionally been designed and built. CellonicsTM technology introduces a simple and swift Carrier - Rate DecodingTM solution to the receiving and decoding of a modulated signal. It encodes and decodes signals at one symbol per cycle-a feature not found elsewhere. Its simplicity will obsolete the super heterodyne receiver design that has been in use since its invention by Major Edward Armstrong in 1918.In fact, according to one e ....etc

Each mobile uses a separate, temporary radio channel to talk to the cell site. The cell site talks to many mobiles at once, using one channel per mobile. Channels use a pair of frequencies for communication. One for transmitting from the cell site, the forward link, and one frequency for the cell site to receive calls from the users, the reverse link.
Communication between mobile units can be either half-duplex or full-duplex. In case of half-duplex, transmit and receive communications between the mobile units are not at the same time, i.e. ta ....etc

PROPULSION SUBSYSTEMS
INTRODUCTION
Spacecraft are provided with sets of propulsive devices so they can maintain three-axis stability, control spin, execute maneuvers, and make minor adjustments in trajectory. The more powerful devices are usually called engines, and they may provide a force of several hundred newtons. These may be used to provide the large torques necessary to maintain stability during a solid rocket motor burn, or they may be the only rockets used for orbit insertion.
Smaller devices, generating betwee ....etc

CHAPTER 1
ABSTRACT
Micro photonics is the successor of electronics .It has many advantageous features for application in space through the combination of micro, nano integrated optics and fiber optic technologies .Based on current technical feasibility, potential impact on space systems and significant benefits; it is proposed that micro photonic satellite navigation systems can be developed with the target of a space demonstration flight .The proposed methodology is generic to the needs of all space craft; can provid ....etc

Propulsion subsystems in a spacecraft aid in preserving the three-axis stability and the control spin. In addition to it, they also help in carrying out manoeuvres and to bring about slight alterations in trajectory. The superior ones called Ëœenginesâ„¢ can infact, generate an acceleration of large torques in volume to sustain the stability of a solid rocket motor during burning phase. The delta-V for simple tasks like the interplanetary trajectory correction manoeuvres, orbit trim manoeuvres, reaction wheel de-saturation manoeuvres and ....etc

Abstract
In traditional methodologies for mechatronic design, the design processes of the mechanical structure, the electromechanical actuators and the control system, is more or less independent of each other. The mechanical structure is usually designed first, then fitted with off-the-shelf electric motors and drive electronics, and finally, a controller is designed for the already existing physical system. This approach leads to that many of the possible advantages of mechatronic ....etc

Advance Network-Storage System - SAN & NAS

Abstract :

The storage networking is a dedicated, high-speed network established to directly connect storage peripherals. It allows the direct communication between the storage devices and the client machines on the network. It provides a efficient solution for historical view of server attached storage. The emergence of storage networking brings a new trend in todayâ„¢s networking technology. The two-major components of storage networking are SAN and NAS.
SAN is a storage area network. ....etc

Adaptive Partition Schedulers are a relatively new type of partition scheduler, pioneered with the most recent version of the QNX operating system. Adaptive Partitioning (or AP) allows the real-time system designer to request that a percentage of processing resources be reserved for a particular subsystem (group of threads and/or processes). The operating systems priority driven pre-emptive scheduler will behave in the same way that a non-AP system would until the system is overloaded (i.e. system-wide there is more computation to perform, than ....etc
