FIRE ALARM SYSTEM
.jpg)
An automatic fire alarm system is designed to detect the unwanted presence of fire by monitoring environmental changes associated with combustion. In general, a fire alarm system is classified as either automatically actuated, manually actuated, or both. Automatic fire alarm systems are intended to notify the building occupants to evacuate in the event of a fire or other emergency, report the event to an off-premises location in order to summon emergency services, and to prepare the structure and associated systems to control the spread of fire and smoke.
Handbook of Modern Sensors Physics, Designs, and Applications
A sensor is often defined as a device that receives and responds to a signal or stimulus. This definition is broad. In fact, it is so broad that it covers almost everything from a human eye to a trigger in a pistol. The operator adjusts the level of fluid in the tank by manipulating its valve. Variations in the inlet flow rate, temperature changes (these would alter the fluid’s
viscosity and, consequently, the flow rate through the valve), and similar disturbances must be compensated for by the operator.Without control, the tank is likely to flood, or run dry.

Planning, Design, and Operation of Power Systems and Equipment
The supply of electrical energy at competitive prices, in suffi cient quantity and quality, and under the aspect of safe supply through reliable equipment, system structures and devices is of crucial importance for the economic development of countries and for the well - being of each individual. When planning power systems different boundary conditions must be considered, which are based on regional, structural, technical, environmental and fi nancial facts, having a considerable impact on the technical design in many cases. Each investment decision requires a particularly careful planning and investigation, to which power system engineeringand power system planning contribute substantially.

RELAY TECHNOLOGY
The last thirty years have seen enormous changes in relay technology. The electromechanical relay in all of its different forms has been replaced successively by static, digital and numerical relays, each change bringing with it reductions and size and improvements in functionality. At the same time, reliability levels have been maintained or even improved and availability significantly increased due to techniques not available with older relay types. This represents a tremendous achievement for all those involved in relay design and manufacture. This chapter charts the course of relay technology through the years. As the purpose of the book is to describe modern protection relay practice, it is natural therefore to concentrate on digital and numerical relay technology. The vast number of electromechanical and static relays are still giving dependable service, but descriptions on the technology used must necessarily be somewhat brief.

HVDC WELL PROVEN TECHNOLOGY
A high-voltage, direct current (HVDC) electric power transmission system uses direct current for the bulk transmission of electrical power, in contrast with the more common alternating current systems. For long-distance transmission, HVDC systems may be less expensive and suffer lower electrical losses. Forunderwater power cables, HVDC avoids the heavy currents required by the cable capacitance. For shorter distances, the higher cost of DC conversion equipment compared to an AC system may still be warranted, due to other benefits of direct current links. HVDC allows power transmission between unsynchronized AC distribution systems, and can increase system stability by preventing cascading failures from propagating from one part of a wider power transmission grid to another.

Top 10: Greatest Inventions Of All Time
.jpg)
Inventions are pretty useful things, in fact, inventions are very useful things. People are inventing new things all the time - unfortunately, the vast majority of inventions tend to be utterly useless; but every now and then someone comes up with something that completely changes the world and it is these few ideas that this hub is about. Now, there are, undoubtedly many equally great inventions as those on this list, but unfortunately it's had to be cut down to just 10. Things such as language have been omitted from this list for, while they are, indeed, quite useful, they were more developed out of necessity than invented; the same applies to fire - it has always been present on this earth, all we did was work out how to create it on a whim!
So what are they? Read on....
ENGINEERING CAREER FACTS
Ans:Engineering is an exciting profession, but one of its greatest advantages is that it will leave you time for all the other things in your life that you love!
Q:Do engineers ever work outside?
Ans:Yes! They work in space, underwater and on land. They may be outside to take soil or groundwater samples, supervise construction or testing equipment for firefighters.

DIFFERENCE BETWEEN EARTHING AND GROUNDING
Almost both of these terms are used for same purpose, but still some how they differs.
Here are the some facts.
Here are the some facts.
- In USA term GROUNDING is used but in UK term EARTHING is used.
- GROUNDING is used where electrically excited part of network is taken in account or part of network where the currents are algebraically zero such as VIRTUAL GROUNDING
- Where is the EARTHING is mostly used for the dead part of network i.e any enclouser
- Term EARTHING is mostly used for protection purpose.

LABVIEW VS MATLAB
Actually, either will do, but you need both. While that may seem to be a nearly nonsensical answer, it makes a lot of sense when you think about the characteristics of the two programming paradigms –graphical and textual.
Many younger programmers think of text-based languages as old fashioned. That paradigm has, after all been around since the1940s. Those programmers are quite adept at assembling graphical objects into an interconnected construct that can do pretty much whatever the user wants. Sometimes, they recognize, the objects simply aren’t available to do what needs to be done, at which time they might be forced to do a little text-based programming.

Scientists Fire World’s Most Powerful Laser and Move Closer to Developing Fusion Energy
Scientists in California fired up 192 laser beams simultaneously onto a single, tiny, two-millimeter target, producing and unbelievable 500 trillion watts of energy. To put it into context, that’s about 1,000 times more power than the entire United States uses at any given time. Scientists aren’t just firing off super-powerful lasers for fun, though; the team at the National Ignition Facility ultimately hope that by aiming the 10-story laser at a compressed pellet of hydrogen they’ll be able to kickstart a nuclear fusion reaction and produce an unlimited supply of clean energy.
