HVDC LIGHT TECHNOLOGY ABSTRACT [pic] Transmitting power at high voltage and in DC form instead of AC is a new technology proven to be economic and simple in operation which is HVDC transmission. The HVDC (High Voltage Direct Current) technology is used to transmit electricity over long distances by overhead transmission lines or submarine cables. It is also used to interconnect separate power systems. A further development in this technology is HVDC

Light From personal experience I would say light within architecture is what makes you feel uplifted as you walk into a room or a space. Light can be controlled and manipulated within certain spaces by adding light or having an absence of light. Light can completely change the dynamics of a room or space and can also have a very strong effect on the mood. Light within architecture can either be natural or synthetic‚ both creating a special experience within a room. In my research I will

My Green Light My green light is an ambiguous entity‚ consisting of multiple forms‚ each day varying from the next. This ever-changing pattern in my life is possibly a result of a void left behind from my childhood‚ as my parents had never encouraged or raised any desire to strive for a goal in me. As such I now have an inability to create a permanent goal for myself. My green light‚ in short‚ lacks conviction - it is deprived of the motivation required to maintain my interest‚ and eventually

Chapter 6 Microbial Growth 1 Growth • increase in cellular constituents that may result in: – increase in cell number • e.g.‚ when microorganisms reproduce by budding or binary fission – increase in cell size • e.g.‚ coenocytic microorganisms have nuclear divisions that are not accompanied by cell divisions • microbiologists usually study population growth rather than growth of individual cells 2 The Growth Curve • observed when microorganisms are cultivated in batch

Polarized light are those that are vibrating in one direction- in a single plane such as up and down. Those that are vibrating in more than one direction -- in more than one plane such as both up/down and left/right -- are called unpolarized light. Generally‚ unpolarized light can be considered to be vibrating in a vertical and a horizontal plane. To polarize light‚ one can transmit the light through a polariod filter which will only allow light of single polarity to pass. The resulting light will be

The Light Bulb: One of the Most Useful Inventions in the World People need light to be able to see. In the morning‚ there is sunlight. But in the night‚ people use electric light made from light bulbs. Without light bulbs‚ people would not be able to see and would have to rely on their other senses to do tasks. Without light bulbs‚ our lives would be very different. The light bulb is a very useful invention that people all over the world use every day. The creation of the light bulb can be traced

Speed of Light Determining the speed of light is something that has been a very long and trying process. No one scientist could determine such a thing. Galileo was the first noted scientist to attempt experimentation on the speed of light. Other famous scientist‚ such as‚ Roemer‚ Foucault‚ Fizeau‚ Michelson‚ and Einstein added their own discoveries to the collage of information gathered through the years. Every scientist performed their experiments differently based on the knowledge and ability
