What is the effect of shunt capacitor?
A shunt capacitor creates a low resistance path in a circuit so that electricity can pass around to another point. Shunt capacitors create shorts when they receive abnormally high amounts of voltage to correct series circuits.

A dome valve might be described this way. Take a solid ring to use as a seat. Now cover the ring with a disk shaped like a contact lens or like a snow saucer. That curved surface will sit inside the ring to seal the valve, and to open it, a lever rotates the disk out of the way of the opening. Use the link to a picture of one. Clyde (in the UK) makes them, as do others, but this picture is animated! You'll get to see the dome valve in action, and that will probably make any further explanation unnecessary.
What is the difference between lines and line segments?
A line goes on forever and never ends, on either side.
A line segmentstops and has two end points.

Are radiators correctly named?
Typically, radiators transfer heat to their environment by both radiation of infrared wavelengths and convection via air (or water, if the radiator is immersed in water).
How much IR radiation versus how much convective transfer depends on the specifics. For a very general answer, radiator is a simple, useful name. It is hard to see what changing it would accomplish.
In electronics, things which dump heat from components to environment are called heat sinks. This is not really an improvement.
A "radiator" in a room could be called "heater".
Any other ideas out there.
How do you define Repetitive Peak off-state Voltage VDRM?
If the MT2 voltage exceeds VDRM such as might occur during severe and abnormal mains transient conditions, MT2-MT1 leakage will reach a point where the triac will spontaneously break over into conduction.
Determining the Coefficient of Uniformity (Cu) and Coefficient of Curvature (Cc) only has meaning when classifying coarse-grained soils, i.e. clean gravels (GW or GP) and clean sands (SW or SP) having more than 50% of material larger than No. 200 sieve with less than 5% fines. Gravels and sands with more than 12% fines (GM, GC, SM, SC) are distinguished using Atterberg limits. There would be no reason to determine these coefficients for fine-grained soils (i.e. clay, silt and peat).

What is the difference between linear scale and representative fraction?
a linear scale is a special kind of ruler that is divided into units of distance
a representative..... what ever the scales called lol is a scale that is a ratio and doesn't use words in the measurment... it's an extended version of a large- scale map

After working in an Indian Tender System for a long time, I found that most of entrepreneurs are not fully aware of this essential system which is capable to raise their business to a peak. I found that most of them are uncomfortable with this system. But now a day's there are lots of Tender Service providers available in the market which helps you to participate in Tender System. We will talk later about such services but right now let's start talk from the base of the Tender System.
Basically Tender is a platform generated to offer a competition between different bidders offering same work, supply or service so that the quality work will be obtained at reasonable cost. However such process must ensure that there are no loopholes in the system so that any individual has a back door entrance or having an underhand connection. Generally tenders are published by Government sector however huge Private sector also publishes tenders for their required work service or supply.
There are different types of tenders, classified by different categories. They can be classified as follows
Tender according to their Sector
- Government Sector Tender
- Private Sector Tender
- PSU(Public Sector Undertaking) Tender
- Open Tendering
- Restricted Tendering
Tenders according to stage
- Single Stage Tendering
- Multi Stage Tendering
- According to the Technical and financial selection:In this type of system there are two proposals placed, one for technical proposal and financial proposal. First the technical proposal is reviewed and evaluated followed by financial Proposal
- According to the Open tendering and then restricted tendering:In this type of system first the tender is being published as open tender and then the few selected individual will be invited to take part further.
- Expressions of interest (EOI) - The participants are shortlisted before detailed declaration of project.
- Request for information (RFI) - It is similar to EOI in which the publisher wants to gather information about some specific parties/companies and then the eligible one will be invited to participate.
- Request for proposal (RFP) - The companies/Parties has to submit only technical proposal as innovative solution is needed.
- Request for quotation (RFQ) -Used when there is a specific requirement of goods or service. The best priced quotation get the tender.
- Request for tender (RFT) - It is just an open tendering and the advertisement has been given in public media like newspaper, Website, etc.
What is the outside of the space shuttle made out of?
Most of the surface of the shuttle is covered with special insulating materials designed to protect the airframe and the people inside from the extreme heat of re-entry. The insulating materials also protect them from the cold temperatures and radiation of space while they are aloft. Different areas have different properties, depending on the amount of heat protection required.
The nose cap and wing leading edges are exposed to the highest heat during reentry - more than 1,260 °C (2,300 °F). Carbon fiber-reinforced carbon (aka carbon-carbon, abbreviated C/C) is used here.Note that while C/C has excellent thermal resistance & thermal shock resistance and a low thermal expansion coefficient, it is not as impact resistant as some of the other materials. It is believed that damage sustained during takeoff to the C/C on the leading edge of one of the wings to the space shuttle Columbia was the cause of the catastrophic failure during reentry that destroyed that shuttle.
Most of the underside of the fuselage is covered with either high-temperature reusable surface insulation (HRSI) tiles (coated LI-900 Silica ceramics) or fibrous refractory composite insulation (FRCI) tiles. These are a little tougher than the C/C and tolerate temperatures up to about 1,260 °C (2,300 °F).
Flexible Insulation Blankets (FIB), a quilted, flexible blanket-like surface insulation is used where reentry temperature is below 649 °C (1,200 °F). Earlier shuttles used Low-temperature Reusable Surface Insulation (LRSI) tiles on the upper fuselage and some may remain, but most or all of these were replaced by FIB as the shuttles were refurbished after each flight.
Starting in 1996 some tiles on the belly of the shuttle and elsewhere were also replaced with Toughened Unipiece Fibrous Insulation (TUFI) tiles.
The top and sides of the shuttle are exposed to much lower temperatures so white Nomex felt blankets are used on the upper payload bay doors, portions of the midfuselage and aft fuselage sides, portions of the upper wing surface and a portion of the OMS/RCS (Orbital Maneuvering System/Reaction Control System) pods. Nomex is a flame resistant meta-aramid, kind of like Kevlar. Kevlar is a para-aramid), but stiffer and with better temperature, chemical, and radiation resistance.
Each type of insulation has specific heat protection, impact resistance, and weight characteristics, which determine the locations where it is used and the amount used.

What is the function of splitter?
Splitters typically have 3 labels: ADSL, Phone and Line. To use a splitter you connect your telephone devices (eg phone, fax or answering machine) to the connection labelled phone, your ADSL modem to the ADSL connection and the line to the wall socket. If you have other telephone wall sockets in the property on the same telephone line you will need to plug in filters between the phone and the wall socket.
In addition to the user installable spliter in the photograph above, you can have a central splitter (see right) installed by a telephone technician. A central splitter is installed on the telephone line before the first phone point in the property. Thus the central splitter protects the all the phone exensions from the ADSL signal. A new phone point is wired into the central ADSL splitter specifically for the ADSL modem. The ADSL modem will not work on any other point in the property.
Central Splitters are sometimes used when user installable splitters and filters do not result in a reliable ADSL connection
What will a UPS be used for in a building?
To provide power to essential equipment
ANSWER: it does not provide any power at all Not until there is a input power interruption then the UPS will take over the function of providing power to the building or even facility.
Uninterpretable Power System It works continuously as a bypass without power delivery to the facility.
How do you do Matrix on pedestal drill machine?
To perform matrix drilling on a pedestal drill machine, first, secure the material firmly on the drill table using clamps. Select the appropriate drill bit for your matrix design and adjust the speed settings based on the material type. Carefully align the drill bit with your marked points on the material, then gradually lower the drill to create the desired matrix pattern. Always wear safety gear, such as goggles and gloves, and ensure the area is clear of obstructions before starting.
