understood. In reality‚ of course‚ electricity is very different from any other product – it is generated far from the point of use‚ is fed to the grid together with the output of many other generators and arrives at the point of use via several transformers and many Kilometers of overhead and possibly underground cabling. Where the industry has been privatized‚ these network assets will be owned‚ managed and maintained by a number of different organizations. Assuring

He first illustrated us a robot and asked: “What is your first impre -ssion if you think of a robot?”‚ almost all of us answered the same answer‚ which is a robot from the movie “Transformers” named “Megatron”‚ then he showed us what a robot looks like in real life. He showed is some pictures. Robots in real life are just arms or half body humanoids. He showed us how they work and entertained us

DTMF BASED HOME APPLIANCE CONTROL SUBMITTED BY ABSTRACT Traditionally electrical appliances in a home are controlled via switches that regulate the electricity to these devices. As the world gets more and more technologically advanced‚ we find new technology coming in deeper and deeper into our personal lives even at home. Home automation is becoming more and more popular around the world and is becoming a common practice. The process of home automation works by making everything in the house

ABSTRACT The manual method of synchronization demands a skilled operator and the method is suitable for no load operation or normal frequency condition. under emergency condition such as lowering of frequency or synchronizing of large machines a very fast action is needed‚ which may not be possible for a human operator. Thus there is a need of autosynchroniser in a power station or in an industrial establishment where generator are employed. This paper describes a microprocessor based set

TRANSFER OF PROPERTY IN UNASCERTAINED AND FUTURE GOODS INTRODUCTION: Where there is contract for the sale of unascertained or future goods‚ the property therein does not pass at the time of making of the contract. The property in unascertained goods cannot pass until the goods are ascertained . Similarly‚ if the subject- matter is future goods ‚ the contract operates as an agreement to sell ‚ i.e.‚ the buyer does not become the owner at the time of making of the contract. After the goods have been

My situation may not sound as fun as saving the world alongside Transformers‚ but with braces‚ my teeth are straighter and my personality is stronger. Despite my “metal mouth” status‚ I didn’t allow my braces to hide my face from the world. Braces are not just corrective devices -- they are fashionable accessories. They’re

Small inexpensive wall tranformers with variable output voltage are available from any electronics shop and supermarket. Those transformers are easily available‚ but usually their voltage regulation is very poor‚ which makes then not very usable
