I NTRODUCTION It has been known that use of multiple antennas at transmitter and receiver increases speed of data transmission between communication terminals. However‚ MIMO channel capacity is degraded by correlation and keyhole effects. Because of the keyhole effect [1]‚ [2]‚ the rank of MIMO channel matrix is reduced

CHAPTER 1 INTRODUCTION 1.1 History A forklift (also called a lift truck‚ a high/low‚ a stacker-truck‚ trailer loader‚ side loader or a fork hoist) is a powered industrial truck used to lift and transport materials. The modern forklift was developed in the 1920s by various companies including the transmission manufacturing company Clark and the hoist company Yale & Towne Manufacturing. The forklift has since become an indispensable piece of equipment in manufacturing and warehousing operations

deals with data transfer from one computer to another. It uses C programming and the serial ports of the PCs. The ports are programmed in C. We use MAX 232 to convert RS 232 logic to TTL logic and then an optical transmitter circuit to transmit data via fiber optic cable. The optical transmitter circuit has a LED which is matched as far the cable and MAX 232 is concerned. At the receiver we have an optical receiver circuit which receives data using a photo transistor and a MAX 232 again to convert TTL

TFRH robot is based on embedded system. The TFRH has mainly two Atmel AT89S52 microcontrollers which communicate with each other via an RF module 434 Mhz. This will be explained in the forthcoming sections. The TFRH is based on 8-bit microcontroller The IC used was Atmel AT89S52 ICS. The hardware cost is reduced by removing various sub ICs used in the design. The design part had successfully removed the 8255 IC and had used multiplexer cd 4051 to support the 7 different motor for the various function

1] Describe the two branches of the ANS – transmitters‚ transmitter synthesis‚ outflow and major effects of each. The two branches of the Autonomic Nervous System are the sympathetic division and the parasympathetic division. The main process of the sympathetic division is to stimulate the fight-or-flight response in the body‚ which means it is in charge of stimulates actions. In the sympathetic system‚ epinephrine and norepinephrine are the main neurotransmitter. In the sympathetic system

Francisco‚ EECE‚ MSU-IIT Abstract –This project involves discovering how wireless connections occur in the atmosphere using a beam of laser. The project‚ laser communicator‚ uses electromagnetic waves to transfer information without direct connection between the input and output devices. This project will also investigate how the sound waves are transmitted as electrical and light signals through

CHAPTER I INTRODUCTION Most mains-operated equipment in use today is connected to the supply via plugs and sockets. These are generally acceptable in benign environments‚ but can be unsafe or have limited life in the presence of moisture. In explosive atmospheres and in undersea applications‚ special connectors must be used. This paper describes a technique‚ the contactless energy transfer system (CETS)‚ by which electrical energy may be transmitted‚ without electrical connection or physical

Is Individuality Equal? Fahrenheit 451‚ created by Ray Bradbury‚ is a book about a man that lives in an authoritarian society. The main character‚ Guy Montag‚ deals with internal and external conflict. He struggles with himself and his occupation as a firefighter. “Harrison Bergeron” is a short story written by Kurt Vonnegut‚ Jr. and it is also takes place in an authoritarian society. The main character‚ Harrison Bergeron‚ and his society were forced to be

INTRODUCTION Deadweight testers are used as a for accurate measurement to calibrate pressure gauges‚ transmitters‚ transducers‚ recorders and controllers. Deadweight testers are very accurate‚ they produce pressure by applying force using calibrated stainless steel or brass weights over a predetermined area. There are numerous models available to meet specific applications. A typical deadweight tester consists self-contained pump for the generation of pressure‚ they also include a piston‚ cylinder
