Engineering

1. heat. If it's hot enough, blackbody radiation (e.g. incandescent light bulb)

2. Electromagnetic radiation (radio waves, magnetic or electric coupling to adjacent conductors) if the current is changing.

Before I list the advantages and disadvantages, it is important to note that Hydrogen is simply a medium with which to store energy, it is NOT an energy source, such as wood, gasoline, or atomic energy. The reason for this, is that Hydrogen does not exist in nature in large quantities, except in molecular compounds of one form or another... thus, to get Hydrogen, you must first extract the Hydrogen atoms from another molecular compound, such as water (Which contains Hydrogen and Oxygen) or even from Gasoline (which contains Hydrogen, Carbon, and Oxygen). In fact, a gallon of gasoline even contains more Hydrogen than a gallon of Liquid Hydrogen.

Thus, it requires us to spend energy to create hydrogen to use in a fuel cell or combustion engine, unlike naturally occurring fuel sources like Wood, which grow/form on their own and only require us to release the energy through burning it (or splitting the atom like in Nuclear Fission). Gasoline is considered a fuel source because even though it needs to be refined, the energy it provides is greater than the energy it takes to refine it. The same is not true for Hydrogen.

Some of the advantages of Hydrogen:

-It no longer requires us to be reliant on Gasoline as an energy source.

-It burns MUCH cleaner than other fuels, since it's only by-product is water.

-In Fuel Cell use, it requires no combustion, which means fewer moving parts that can break in the engine.

-It is in a small list of fuels which are: widely available, stable enough to be transported safely, and has a sufficient energy density so the fuel tank does not need to be larger than the rest of the vehicle.

-Hydrogen can be created wherever it is needed, so you will no longer need to "Ship" it from the refinery to the gas station. Gas stations could simply have their own generators on-site, allowing them to ship stable liquids like water to extract the Hydrogen from.

Some of the dis-advantages of Hydrogen:

-It takes more power to create it than it generates, so the power needs to come from somewhere else, which can be hydroelectric, coal, solar, geothermal, etc.

-Its energy density is significantly lower than gasoline, so you need a larger fuel tank to generate the same amount of power.

-Much like gasoline, it is flammable, but can be explosive if mixed with enough oxygen, so the fuel tank must be protected extremely well.

-The fuel infrastructure in most countries is not set up for Hydrogen, so gasoline stations would need to be converted in large numbers, quickly.

There are a number of factors that would affect the answer to this question including torque, shaft speeds, load etc. This is why there are many methods of delivering force to remote locations (worm, belt, chain). I believe some of the advantages when working with belts are - reduced friction losses as the belt has more contact area - decreased energy loss through vibration (in effect a belt has vibration dampening) - belt breakage usually seperates the drive system causing little damge or danger unlike chain If someone can answer the physics side of this I would be most appreciative as most of these answers come from car knowlege (see variable belt drive vs. timing chain).

There are a number of different types of lathe. We usually separate them out by whether they are for wood or metal (and other stuff like plastic). The things is, they all do essentially the same thing: they turn a workpiece between two centers and allow the user to apply a tool to remove material from the rotating mass of "stuff" being worked, or, as is said by those involved, turned. The earliest lathes did thi - turned the work so a tool could be used on that material. And we do it pretty much the same way today. The metal lathe most often has a chuck on the headstock (the driven end) in which work can be clamped, and this affords an "open end" on the material so it doesn't have to be supported at the "tail end" of the lathe to work the material. (You aren't turning between centers.) A number of metal lathes are computer controlled (the so-called computer numeric controlled or CNC machines), and they can do a lot of things very quickly and with a high degree of accuracy. And all if it is repeatable. Need some pistons made for your engine? We can do that. Many wood lathes have a faceplate attachment that a wood turner can affix a chunk of wood to so he can turn, say, a bowl. That way the wood can be supported on just the one end and the bowl can be hollowed out. There are lots of wood turners out there, and they make some fabulous stuff. We often say, "I'm turning (something) on a lathe." It could be a wooden bowl to mix pie dough in or a rolling pin for rolling out that pie dough. Certainly it could be any one of a zillion machined parts for aircraft or automotive applications, or just about anything else. There are a lot of things we use every day that have been turned on a lathe, though many of them may not be where we can see them, like a number of engine parts in a car. The largest part of the lathe (almost always) is the bed of the machine. It is the "frame" onto which the headstock and the tailstock are fastened. The headstock has in it the rotating (driven) spindle on which a chuck or faceplate can be fastened. On the bed, the top of it is generally machined to create the ways on which the tool rest or (in the case of a metal lathe) the carriage(with its cross slide and tool post) can sit and move precisely along the length of the bed. There are some other parts and a host of attachments to the lathe. Pictures may very well help you see things. Links are provided to the Wikipedia articles on the lathes, and a link is provided to some "lathe" video clips put up on YouTube. There are a lot(!) of short posts there on lathe work. Check a few out.

i would suppose that it's because the incline is greatest then..but i suppose rocket means "something unmanned lol". the idea i have in my head says something along the lines of, the object has a path of of travel and when its moving it has a projected path of travel. so if the propellant was to be cut off when the rocket is traveling 100mph, it's not just going to stop..it has energy yet to be released. also i believe that things weigh more the faster they are going, according to Einsteins theory of relativity. but when things aren't moving they don't have a projected path of travel that is anywhere else other than where it is, then. so probably because motion must be established, and once it is, the forward motion of the object aids the propellant, if you will..or is less resistance for the propellant.

Peak to Peak is the most positive peak to the negative peak value. Or find any peak value and multiply by 2.

Either drag (air resistance) slows the aircraft down, or lift (Bernoulli's principle) raises it up. When more air goes under the wing than over it, the aircraft "wants" to move up because objects favor movement into low pressure zones.

File based approach can be attributed to two factors:

1. the definition of the data is embedded in the application programs, rather than being stored separately and independently.

2. there is no control over the access and manipulation of data beyond that imposed by the application programs.

To become more effective, a new approach was required. What emerged were the database and the DBMS (Database management system).

delta modulation refers to the procedure of encoding and thereby transmitting only the difference between consecutive samples instead of sending each of the samples themselves. This method is useful only when the vaiation in the amplitude of the signal is small, otherwise, it leads to a phenomenon called "slope overload".

Pulse code modulation is the procedure where each of the levels of an analog signal is assigned a value closest ro a quantizer level used to quantize the signal...


Another method of PCM that can be confused with Delta Modulation is the D(ifferential)PCM. Here, the difference between the signals is encoded based on its magnitude..

Aqueducts supplied ancient Roman cities with water from their sources on the mountians. It took a good deal of engineering to build these aqueducts that were many miles long. They were built all over ancient Rome's empire.

A railroad engineer can operate a train for 12 hours, there is no federal restriction on how long they may work, but an engineer, conductor, or brakeman must have 10 hours rest before the start of each shift.

A strong enough magnet brought close enough to the screen or to certain other parts of a television or computer monitor that uses a cathode ray tube will distort the displayed image.

This happens because a cathode ray tube image is created by shooting electrons at a phosphor-coated layer that glows where the electron stream strikes it. The stream of electrons is focused and targeted by magnetic fields within the TV tube. A strong enough magnetic field from another source will send the beam of electrons off target, distorting the image.

This does NOT happen with modern flat screen TVs and computer monitors because they do not use cathode ray tube technology to create the image.

The picture as seen on TV screen is due to moving charged particles (electrons).

The rainbow turns your eye into a rainbow that poops unicorns LOL jk, here the real answer:

it is flipped 180 degrees, bounced off the inside, and received in the cones. the brain then processes and flips the image.

In JFK's inaugural address, he says "United there is little we cannot do in a host of cooperative ventures. Divided there is little we can do." This is an example of inversion, specifically the part where he says "United there is little we cannot do," versus "Divided there is little we can do." (The actual definition of inversion is: Inverted order of words in a sentence (variation of the subject-ver-object order). Source: The Language of Composition. Editors: Shea, Scanlon, Aufses

1. They are black box - that is the knowledge of its internal working is never known

2. To fully implement a standard neural network architecture would require lots of computational resources - for example you might need like 100,000 Processors connected in parallel to fully implement a neural network that would "somewhat" mimic the neural network of a cat's brain - or I may say its a greater computational burden

3. Remember the No Free Lunch Theorem - a method good for solving 1 problem might not be as good for solving some other problem - Neural Networks though they behave and mimic the human brain they are still limited to specific problems when applied

4. Since applying neural network for human-related problems requires Time to be taken into consideration but its been noted that doing so is hard in neural networks

5. The Vapnik-Chervonenkis dimension or VC Dimension of a neural network which is a combinatorial parameter that measures the expressive power of a neural network is still not well understood

6. They are just approximations of a desired solution and errors in them is inevitable

7. Lastly I will add that they require a large amount training set to be trained properly and to give output(s) that would be close enough to the desired output but knowing what amount of training set is enough for a desired output would be totally dependent on the trainer itself - but yes its important that a very large training set is provided so that the neural network would have sufficient understanding of the underlying structure.

Information systems affect organization by creating a better working environment. They provide support for business operations, help with product development, build relationships with customers and suppliers, and help with the business model itself.

When you cannot afford to get the picture yourself i.e you cant get the same picture yourself.

first the engineers can either "MODEL" it or.. there is othe possible ways that they can do it.

It makes the ships center of gravity sink lower in the water. This makes the ship more stable by making it less top heavy and by displacing more water. It gives it a larger base. Hooweestik.
