Xnec2c antenna simulation

He's fried his antenna.

Climb the tv antenna!

This is a planar graph.

Puzzle game involving untangling planar graphs

This is its antenna right there.

That was our HF radio antenna.

Looks like an antenna or... or...

Here's an example of a planar graph.

Here's a planar graph on five nodes.

Who was it helped fix my antenna?

Is there an antenna on the island?

We're tuning her antenna, as it were.

We had a planar graph. amp gt amp gt About the planar graphs. amp gt amp gt Yup.

The man tried to install his own antenna.

People ask me how they make the antenna.

I invented a plasma antenna, to shift gears.

We've got a problem with the antenna ringing.

The TV antenna broke away in last night's storm.

Here's a planar graph a bunch of nodes and edges.

They can be planar formations, they can be three dimensional formations.

You'll get a clear picture with this antenna on the roof.

That's the cable for the antenna so you can watch TV?

I was told that the loss of an antenna wasn't critical...

We can build any planar graph by iteratively adding nodes and edges.

To do that we're going to need another concept about planar graphs.

For any planar graph, n m or is equal to 2. Really?

And that shark leaping there, if you look carefully, has an antenna.

What about coloring a graph with four colors if its a planar graph.

It's a piece of plastic with a Radio Shack antenna attached to it.

It's just a hollow piece of plastic with an antenna that swivels around.

Let's think about the colorability of planar graphs. In particular, here's a decision problem.

There's going to be some graphs that can't be drawn as a planar graph. If we add this edge between this node and this node, the resulting graph is no longer planar.

This down here, if the camera can see that, that is a small antenna.

But like any long length of charged wire, it also inadvertently became an antenna.

As you can see here, they collapse from a three dimensional formation into planar formation.

We're also going to now talk about a notion of regions in a planar graph.

Any lines drawn across co planar surfaces can be erased to form one larger surface.

We're given a graph G and a number K. Is planar graph G K colorable?

like a tuning fork the antenna resonates, and there's more energy coming out of the antenna than there is the backscatter from the ground that we're trying to analyze, taking too much processing.

I says, Why don't we make an antenna that only exists when you want it?

The town mayor made a narrow escape from the waves by clinging onto this antenna.

Another category of graphs that are very important and come up a lot are planar graphs.
