Comparisons

People often examine things and objects by comparing their similarities or differences in order to judge the specific characteristics, qualities and the degree of their merit. This category includes all the questions and answers to relate things with their similarities and to distinguish with their differences that decide their specific nature in contrast to their counterparts being compared.

What is a comparison between two things that states that the first thing is the second thing?

A metaphor. Examples of metaphors are: "At night the sea is a black abyss that stretches on through eternity."

"But soft, what light through yonder window breaks? It is the East, and Juliet is the Sun."

In contrast, a simile is a comparison that uses "like" or "as." A metaphor states that Thing 1 IS Thing 2. A simile merely states that Thing 1 is similar or the same as Thing 2.

Examples of similes are: "Her contemptuous laughter washed over him like a bucket of freezing water."

"He opened his eyes to see her face looming above him in the darkness, as luminous and radiant as the moon hanging in the night sky outside."

Comparison between elastic and inelastic collision?

Elastic collison => Momentum and kinetic energy of colliding bodies are conserved.

Colliding bodies should be perfectly elastic and they regain their previous configuration after collison is over.

InElastic collison => Momentum is conserved but kinetic energy of colliding bodies are not conserved. Colliding bodies are not perfectly elastic. Their shape and size(configuration) changes after the collison.

Comparison between Honeywell and yokogawa DCS?

I've spent a few years involved in the specification and requisitioning of a large (10 000+ I/O) Honeywell DCS, and before that I spent 2 years doing the same for a large yokogawa DCS.

When it came to both the hardware performance/capability and the quality of engineering, there is no comparison, Yokogawa won by a long way. I can't comment on price.

A few gripes I've had with Honeywell:

1) Inter-plant signals - signals had to be hardwired between controllers if they are to be passed from one community/domain to another to maintain a scan rate of 1 second. Sort of takes word 'distributed' out of DCS.

2) Graphics are very limited in the number of tags/variables and many of them had to be split up - much to the operators dismay.

3) Sheer volume of unnecessary documentation - for example, they submitted a 50 page document for review describing the typical software for a differential pressure indication.

The industry has changed a lot of the past few years especially with increased pressure for good resources so I'm sure all DCS vendors are subjected to the same engineering quality problems. Therefore will not go into the engineering issues we had.

Hope that helps.

=====

I am not fully agree with the above explaination. You may be a Yokogawa supporter, but don't just give false information to other.

1) Inter plant connectivity can be achieved through DSA (Distributed Server Architecture) configuration.

2) Graphics are built for man-machine interface only. Off course, if you want the whole plant to be in one graphic page then that's create performance issue. If you built and arrange your graphic pages properly, there should not be any issue raised.

3) Nobody will agree that 50pages are submitted for a pressure loop description. I have seen SDM (Software Design Manual) from Honeywell used for a particular project. It was nice and explanatory.

The one u said on the new Honeywell DCS ... EPKS ....

I am using Honeywell for a long time.... but as a customer we are looking at the work quality

and products ..... I am not sure about Yokogawa but I believe it does have similar problem like Honeywell...

Products problem:

1. Too many bugs

2. No experties in Malaysia for new products

3. SUpport team lack of compentency

4. Product reliability and availability weak...

and all of this contribute more cost to customer where they had to pay them just to fixing things that they also not really expert...

this the reason why user keep asking and concern on the cost for them to repair.

anyway .. both system has their own weakness... so the only ways is how we ensure they

deliver the good quality one..

Comparison between Maslow and McClelland's Need theories?

Maslow's hierarchy of needs theory

According to this theory, people have layers of needs, and until the lower-layer needs are satisfied, they will not move to satisfy the upper-layer needs. For example, if you are unemployed and broke, and as a result your very survival is in danger, you don't care about buying health insurance or life insurance or dating to look for a life partner.

McClelland's achievement motivation theory

According to this theory, the following three needs motivate people:

• Achievement - This is the need to perform well, achieve success, and get recognized for it. The key idea here is the drive to excel.

• Affiliation - This is the need or desire for good relationships at work. You want to feel connected at work.

• Power - This is the desire to move things, to influence people or events. The key term here is the world dominance or making a difference.

How is a cyclotron constructed and how does it work?

The cyclotron is a charged particle accelerator. It worked well enough to net Ernie Lawrence, its inventor, a Nobel Prize in physics for creating and developing it. (Props to Hungarian Sándor Gaál, but word on the street is that he was a bit later than our boy Ernie.) This thing isn't all the complex, but since we're here on the page, we'll have to jump around a little bit to get it all laid out. Better buckle up. We'll touch on theory here and there and do the mechanics along the way in bits and pieces to arrive at a working end product. Hopefully. Let's build one, plug it in and fire it up to see what happens. Use the links where suggested. (You won't be Rickrolled. Promise.) We'll start with a bit of background. Ready? Step up.

One of the four basic forces in the universe is the electromagnetic force. Not the electric force. Not the magnetic force. The electromagnetic force. Electrostatics and magnetics are inseparably intertwined. Any time a charged particle moves, it creates a little magnetic field around its path of travel. All the time. Every time. That sets the stage for interaction between charged particles and magnetic fields. Any time there is relative motion between a charged particle and a magnetic field, a force will act between them. Movement can result. Relative motion means the charged particle must be moving "across" or "through" magnetic lines of force and not "along" or parallel with them. You already know the basic law of electrostatics: opposite charges attract and like charges repel, yes? Good. Let's jump.

Picture a hockey puck. Now picture it bigger in diameter, but not in thickness. Make it as big as, say, a small dinner plate. Got it? A thin disc is what we've got. Now picture it made of metal. Now picture it hollow so we have only the shell. Just a dinner plate sized disc that's hollow. We good? Now cut it in half across its diameter and you'll have two things shaped like the letter "D" and they'll be hollow. Put them in a fixture to hold them in the position they were just after you cut them. What you've got is your original disc cut in half with the openings facing each other and a little gap between them. That hollow space inside is the "cavity" and it's going to be the "playground" for our particles. And the gap between them is going to let us hook up a power supply to the two halves, to the two D's, and charge them oppositely when we need to. A couple more things and we're tight.

First, punch a hole in the outside of a D to form an exit from the cavity. Then put the whole thing in a close-fitting package so we can pump all the air out from inside and around the D's and their little electrical insulators that support them. Remember the little hole we made in one of the D's? We need to have a hole in our package to let the particles out after they come out the hole in the D. Now focus. The particles are going to be coming out in a tangent from the edge of the disc. Picture this clearly. A particle is going to be moving along the inside edge of the cavity in a virtual circle. It's going to be moving in a circular path, and will slip out the exit and travel in a straight (tangent) line coming out from there, and that's the way we have to arrange our "exit tunnel" from the setup. If someone was swinging a weight on a string about himself, and the string broke, the weight would fly off in a straight line, a tangent, from the point where it was when the string broke. Our hole in the D and the outlet tunnel or tube will facilitate that kind of exit, will make up that path, okay? Check the GSU hyperphysics link at this point to see a drawing of the internal setup and then come back 'cause we're ready to jump. Here we go.

We're gonna build a big, big electromagnet. Picture a big log. Make it about, what the heck, three feet in diameter. It's big. And pretty long. Now picture it made of iron. One big, cylindrical chunk of iron. Then wrap about a zillion turns of heavy gauge wire around the middle. Leave room at the ends of the log so we can bend them. Now stand the log on end and bend both ends over and toward each other to make a big letter "C" out of them. Got it? Our coil is in the middle of the "back" of the C and the ends come over, come around and come in to create a little gap between them. Just big enough to put our little package in. Our package is the set of D's. It just fits inside the gap at the ends of the big C we just made. If we then take the ends of the wire we used to wrap the coil and hook them to a giant DC source, we will get a ton of current through the coil and create a super electromagnet with a crazy dense field across the little gap where our sealed and evacuated package is going to be sitting. The lines of force of the magnetic field are straight across the gap of the C, and they are perpendicular to the plane of our D's in our package. That's an important concept. The plane of the D's is at a right angle to the lines of force of the standing magnetic field were are generating when we turn on the electromagnet. Go to the Wikipedia cyclotron article at this point and scroll down to the picture of the young woman standing outside next to a cyclotron electromagnet and pole piece assembly. You can see this one is actually two "C's" (they're the dark things at the near and far end) that support the white circular structures. The little space between the white thingies is where our package with the D's will go. It's gonna sit right between the pole pieces. We good?

Let's review. We've got a couple of hollow D's sitting on insulators with a tiny gap between them. We've got a wire hooked to each D so we can electrify them. We've got all that inside a case so we can pump down the pressure and create a vacuum. The package is sitting inside a sick magnetic field that we are maintaining by using enough electricity (though we use DC) to power up a small town. Let's hook up our "D wires" to a large, high frequency alternating voltage source so we can fire the thing up and get down.

Though the cyclotron can be used to accelerate electrons or protons, protons were arguably more useful to physics. And they're a lot more fun! Hey, we just built a particle accelerator! You wanna shoot ping pong balls out of it or bowling balls, hmm? Thought so. We need some protons. Has UPS come yet? Forget it. We'll just make some. Where's the hydrogen? Get that gas over here. We pump some hydrogen into a "stripper" that uses high voltage to ionize the gas. With the electron torn away, we have a hydrogen nucleus. A proton. Sometimes with a neutron. Or even two. We get these into the middle of the cavity created by our hollow D's. Now the fun begins!

We apply a high voltage to the D's. One D is positive and the other D is negative. The protons are positive. They are electrostatically attracted to the negative D and repelled by the positive D and they move. Oh, but bad news. There is a wicked magnetic field that they have to swim through. So they are deflected. It's gets tricky here, but you've come this far. It's only one more jump. As the protons are pushed by one D and pulled by the other, they move and cross the gap. And as they cross the gap, we reverse the polarity of the voltage to the D's. The protons are, like, "We just came from over there because we were pushed out by the positive and pulled here by the negative and now you go and reverse the polarity of the voltage on the D's and we have to go back! What's up with that?" So the protons are going to want to respond to the changing voltage and go back and forth across the gap between the D's. But with the giant magnetic field through which those little guys have to move, they travel in an arc. What happens is that as they move back and forth and gain energy and move in an arc, they actually spiral from inside to outside of the D's. Break here to focus on this:

This complex motion, the vectors carved out by the moving charges in response to the electrostatic fields and to the "skew" created when their own motion-generated magnetic field interacts with the standing magnetic field we created with our magnet, is the heart and soul of what makes this machine work, is what this machine is all about.

In finishing, the positive ions (protons, plus, maybe a neutron or even two) gain energy with every moment and end up really hauling butt by the time they reach the outer edge of the playground. They fly out through the outlet (on that tangent we talked about) and down the goodbye tunnel we set up in our package and end up slamming into a target we place at the end of the run. Blamm! Proton-target interaction. Scattering. And if we "rig" our hydrogen to improve heavy hydrogen concentration a la heavy water, we can shoot bigger bullets on a regular basis. The capture of heavy hydrogen will allow us to up the percentage of proton-neutron nuclei and proton-neutron-neutron nuclei we use as the bullets in our particle cannon. It just seems to keep getting better! Imagine the possibilities for scattering.

Skim the articles and tighten your grip on the operation of the machine that changed physics. We've skipped some little things, and (probably more importantly) all the tedious math associated with the operation of the machine. By just sticking to basics and sketching it, we've got a fairly good idea of how the thing works. By the way, the math isn't really tedious. And it isn't that tough. As your math skillz improve, you can come back and tear up the formulae presented in all the articles. It isn't that difficult, really. It's not rocket science. Just nuclear physics. Big difference. Hey look, Mom! I'm doing nuclear physics!

What is the definition of firmament?

The vault of the sky.

To the ancients, the firmament was a solid dome that held up the primeval waters, while the sun and moon were in the sky below the firmament. Stars were thought to be holes in the firmament, allowing the light of the heavens to shine through.

Amongst Talmudic scholars the firmament is generally accepted to mean outer space or the earth's atmosphere. The Talmud actually teaches that there are seven firmaments, the one we see (the sky) being the first. It is also taught that the firmament is made up of fire and water, basically describing the Earth's atmosphere.

The firmament was a layer of water vapor that at one time covered the entire earth. We see the remnants of that layer today in the form of clouds.

Answer The Jewish Encyclopedia describes the Firmament as follows: "The Hebrews regarded the earth as a plain or a hill figured like a hemisphere, swimming on water. Over this is arched the solid vault of heaven. To this vault are fastened the lights, the stars. So slight is this elevation that birds may rise to it and fly along its expanse."

The book of Genesis goes on to mention lights being placed in the firmament (Genesis 1:14-17):

And God said, "Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years: And let them be for lights in the firmament of the heaven to give light upon the earth": and it was so. And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: the stars also.

According to traditional commentary, the word Rakia (firmament), like certain other words, may indicate more than one thing. In Genesis 1:20 concerning the birds, it refers to the vault of the sky, against which we see the birds fly. In 1:14 concerning the sun, moon and stars, it refers to what we call outer space. And in the Talmud, Hagigah ch.2 concerning the upper worlds, it refers to the limit between each two of the upper worlds.
