PLC BASED DOOR OPEN AND CLOSE SYSTEM



WORKING PRINICIPLE:
The microcontroller based Door locker is an access control system that allows only authorized persons to access a restricted area. The system is fully controlled by the 8 bit microcontroller PLC. The password is stored in the EPROM so that we can change it at any time. The system has a Keypad by which the password can be entered through it. When the entered password equals with the password stored in ....etc

Introduction

Over the last few years, the interest for connecting computers and computer supported devices to wireless networks has steadily increased. Computers are becoming more and more seamlessly integrated with everyday equipment and prices are dropping. At the same time wireless networking technologies, such as Bluetooth and IEEE 802.11b WLAN , are emerging. This gives rise to many new fascinating scenarios in areas such as health care, safety and security, transportation, and processing industry. Small devices such as sensors can be ....etc

ABSTRACT
lwIP is an implementation of the TCP/IP protocol stack.. Interest for connecting small devices to existing network infrastructure such as global internet is steadily increasing. Such devices often has very limited CPU and memory resources and may not able to run an instance of TCP/IP protocol suite.
The focus of the lwIP stack is to reduce memory usage and code size, making lwIP suitable for use in small clients with very limited resources such as embedded systems. In order to reduce processing and memory deman ....etc

RATE & DELAY GUARANTEES PROVIDED BY CLOSE PACKET SWITCHES WITH LOAD BALANCING

Abstract: In this paper, we consider an overarching problem that encompasses both performance metrics. In particular, we study the network capacity problem under a given network lifetime requirement. Specifically, for a wireless sensor network where each node is provisioned with an initial energy, if all nodes are required to live up to a certain lifetime criterion, Since the objective of maximizing the sum of rates of all the nodes in the network can lead to a sev ....etc

Vehicle Ancillary Load Reduction Project Close-Out Report
INTRODUCTION

The amount of fuel used for climate control in vehicles affects our nation’s energy security significantly as it lowers the fuel economy of the 230 million light-duty conventional vehicles in use in the United States today. Researchers at the National Renewable Energy Laboratory (NREL), a U.S. Department of Energy (D ....etc
