Since as per Qs J is a positive no. We can try a pretty small no and check all options.
Let say j=2 and it increase to 3
i) decrease from -3 to -8
ii) decrease from -2 to -4
iii) decrease from 1/4 to 1/9

I $$y = 1 - x^2$$ is the equation of a downward parabola, intercepting the x axis at -1 and 1. So, far away from the roots, the values of the function are decreasing as x increases. YES

II $$y=x-x^2$$ is also the equation of a downward parabola, roots 0 and 1. Again, far away from the roots, the values of the function are decreasing as x increases. YES

III Definitely decreases, the larger the denominator, the smaller the value of the fraction. YES

It can be solved using values

(1) $$1- j^2$$ : Obviously if j increases, value of $$J^2$$ will increase. This will in turn decrease the value of $$1- j^2$$

(2) $$J-J^2$$ = $$J*(1-J)$$

when J=135, we get -135*134
when J=136, we get -136*135
Therefore, from the values we can easily see it is decreasing.

(3) $$1/J^2$$ : as the denominator decrease, so the result will decrease.

As in all three cases, values decrease the answer is E

I. $$1-j^2$$ Of course, a larger portion is taken from 1. Definitely the value will decrease.
II. $$j - j^2$$ I thought of smaller positive consecutive numbers such as 2 and 3. -2 vs. -6 shows a decrease.
$$\frac{1}{j^2}$$ The larger the denominater, the smaller the fraction.

I. As j increases, j^2 will increase too. Therefore 1-j^2 will decrease.
II. j-j^2 = j(1-j). As j increases, 1-j will decrease and be negative. Multiplied by the increased j, this gives us a more negative figure. Therefore j-j^2 will decrease too.
III. Simple reciprocal. As j increases from 135 to 136, 1/j^2 is bound to decrease

E it is.

Assume j increases from 2 to 4
I. $$1 - j^2$$
1- $$2^2$$ = 1-4 = -3
1- $$3^2$$ = 1-9 = -8
So this is true

II. $$j - j^2$$
2- $$2^2$$ = 2-4 = -2
3- $$3^2$$ = 3-9 = -6
So this is true

III. $$\frac{1}{j^2}$$
$$\frac{1}{2^2}$$ = 0.25
$$\frac{1}{4^2}$$ = 0.0XX
So this is true

Therefor , E

# How to Create Custom CLI Commands Using the Symfony Console Component

Difficulty:BeginnerLength:MediumLanguages:

In this article, we're going to explore how you could create custom command-line interface (CLI) commands in your PHP applications using the Symfony Console component. After installing the necessary libraries, we'll create a few handful of examples to demonstrate the concepts of the Console component.

In fact, this component is used by several PHP frameworks to develop CLI applications, and a few popular frameworks are already using this component as a starting point.

## What Is the Console Component?

The Symfony Console component allows you to create custom CLI commands in your PHP applications. If you have ever worked with Laravel or Symfony, you might be aware of the CLI tools they provide in order to ease day-to-day operations like:

• generating scaffolding code
• clearing caches
• installing, enabling and disabling add-on services
• running database migrations
• and more

In the case of Laravel, for example, it comes with the artisan tool which provides plenty of utility commands that make our life easier. You may be surprised to know that the artisan tool is built on top of the Symfony Console component itself! In fact, there are many frameworks that leverage the Console component to build their command-line tools.

In this article, we're going to explore the basics of the Console component so that you can create custom CLI commands in your PHP applications. To start with, we'll go ahead and install the Console component using Composer. After installation, we'll build a few examples for demonstration purposes.

## Installation and Configuration

In this section, we're going to install the Console component that is required in order to create CLI commands in your PHP applications. I assume that you've installed Composer in your system—we'll need it to install the Console component which is available from Packagist.

Once you've installed Composer, go ahead and install the Console component using the following command.

That should have created the composer.json file, which should look like this:

Let's modify the composer.json file to look like the following one:

As we've added a new classmap entry, let's go ahead and update the Composer autoloader by running the following command.

Now, you can use the Console namespace to autoload classes under the src directory.

Creating CLI commands using the Console component is a two-step process.

• First, you need to create a console application which loads the necessary dependencies and registers your custom commands.
• Next, you need to create files for all commands that you have registered with the console application.

### Create the Console Application

In this section, we'll go ahead and create our custom console application.

The proposed directory structure of our console application looks like this.

Go ahead and create the main application file bin/console with the following contents. Please note that there's no file extension, and also make sure that it's executable as well since we'll need to run it from the command line.

The first line in the file #!/usr/bin/env php makes sure that it's run under the PHP environment. Go ahead and try to run it and see how it goes.

Not bad! With just a few lines of code, you have a custom console application rolling at your disposal! But it's not doing anything useful at the moment. In the next section, we'll see how you can create custom commands and register it with our custom console application.

### Create the Hello World Command File

Let's go ahead and create our first custom command: HelloworldCommand. Create the src/App/Commands/HelloworldCommand.php file with the following contents.

There are two main methods that you should create while creating your custom command: configure and execute.

As the name suggests, the configure method allows you to configure your command so that you can set up the command name, a short description of the command, help text, and more. You can also configure arguments for your command if you want to pass parameters while running a command.

In the above example, the command name is set to hello-world. Also, we want to pass a username as the first argument, and hence we've configured it using the addArgument method.

On the other hand, the execute method contains the application logic of the command. In our case, we've kept it pretty simple by displaying Hello World as the output of the command.

Before you can go ahead and actually run this command, you need to register it with the console application which we've created in the previous section. Let's quickly revise the bin/console file to look like the following one.

As you can see, we've used the add method of the Application object to add the HelloworldCommand command. Let's quickly list all the available commands.

As expected, the hello-world command appears in the list of available commands! Go ahead and run it!

So that's how you can set up basic commands!

## A Real-World Example—Clear Cache Command

In the previous section, we built the hello-world command to demonstrate the concepts of the Console component. In this section, we'll go ahead and create a real-world example which demonstrates how you could build a command to clear caches in your application.

### Create the Clear Cache Command File

Go ahead and create the src/App/Commands/ClearcacheCommand.php file with the following contents.

The configure method is pretty much the same, except that we've used the addOption method to add an option to our command. Thus, you could pass group values by using the --groups parameter.

On the other hand, the execute method contains the application logic of our command.

If you want to clear the cache of specific groups, you need to pass group names along with the --group parameter. On the other hand, skip the --group parameter if you want to clear all caches. You may have noticed that we've kept the --group parameter optional by providing the InputOption::VALUE_OPTIONAL value in the third argument of the addOption method.

### Registration and Testing With the Console Application

Before we go ahead and actually run it, let's register the command with our console application.

Now, go ahead and run the bin/console clear-cache command to clear all caches!

Next, if you want to clear specific caches, you could try something like this.

Of course, you will need to implement the actual logic to clear caches, but that should serve as a good starting point.

## Conclusion

Today, we went through one of the popular components provided by the Symfony framework: the Console Component. It's really a useful component should you wish to develop your own CLI application which helps you execute your day-to-day utility tasks with ease.

In the first half, we went through the installation and configuration of the component. Then, in the second half, we created a couple of examples of console commands.

Let us know what you think in the comments below.

# Impedance and frequency-domain

1. Jan 24, 2007

### tandoorichicken

1. The problem statement, all variables and given/known data
This is a general question regarding impedance in circuit analysis.
I know that in order to find the total impedance of a circuit, you transform each element characteristic into the frequency domain, i.e.,
$$R\rightarrow Z_R = R$$,
$$C\rightarrow Z_C = \frac{1}{Cs}$$,
$$L\rightarrow Z_L = Ls$$.

And then sum up the quantities properly to get an equivalent impedance.

My question is, what happens if you transform this quantity back using an inverse transform? Do you get a real resistance value?

2. Jan 24, 2007

### chanvincent

This transformation doesn't have an inverse for the imaginary part, since the effect of capacitor and inductance cancel out each other....

The resistance value is the real part of the impedance... ie Re(Z) = R,

3. Jan 24, 2007

### tandoorichicken

what if its a circuit consisting of only a resistor and a capacitor?

4. Jan 24, 2007

### mjsd

well, why would you expect that in general you get just a purely resistive circuit when you started with a circuit with a resistor, a capacitor and an inductor?

The property of the circuit won't change just because you have tranformed into a more convenient domain (the freq domain in this case) for calculation purposes and then changed it back. If you begin with a 1 ohms and a 2 ohms resistor, then you can say ok, the total R is 3 ohms, so I can replace them with just one 3 ohms resistor. But that's all you have really done in finding the equivalent resistance.

same applies in the case with capacitors and inductors included. you started with R , C, L. Since C and L make up the imagary part (in freq domain) they have a chance to cancel (fully or partially). If they cancel each other fully, then you will end up having just an R in your equivalent circuit. Now if they don't cancel fully you will have either one L or one C (of different value) left pending on the phase of the equivalent resistance in freq domain.

5. Jan 24, 2007

### SGT

In the time domain you can only calculate the impedance of the circuit for specific frequencies. At the resonant frequency, you have a pure resistance, below or over the resonant frequency, you have complex impedances, either RC or LC.
If you have a closed circuit, with sources and/or initial conditions, you can solve the resulting differential equation and have a frequency independent solution.

The prefixed "sudo" command will run "ifconfig eth0 down" with what is essentially administrator privileges in Windows. Currently you have to do some long-winded (long-typed?)

This is because tab completion wipes all characters to the "right" (en-US) of the cursor. I'll use robocopy.exe as an example, which has the following usage: ROBOCOPY source destination [file [file]...] [options] As a contrived example, with [] to designate cursor position when tab is pressed.... 1. standard tab completion: Robocopy.exe C:\windows\in[] 2.

• ## Fix tab expansion of environment variables

Currently, tab expansion works fairly well. However, tab expansion fails when any part of a path uses an environment variable. Please fix this so tab completion (matching files / directories) expands environment variables as part of it's tab completion.

Working example:
1. In cmd.exe, type the following
cd C:\windows
2. Now hit 'tab' key twice
3. Update the cmd.exe line to the following:
cd %windir%\
4. Now hit 'tab' key many times

Results (as expected):
At step 2, the tab cycles through all directories that start with 'c:\windows'.
At step 4, the tab cycles through all subdirectories directly under c:\windows. …

In some cases, Windows Command Prompt work with (environment) variables in its own way, which differs from widespread. E.g. code:

set TEMPVAR=1
if "1"=="1" (
set TEMPVAR=2
echo TEMPVAR="%TEMPVAR%"
)

executed from batchfile, print "1", when most of other shells aor programming languages print "2". Of course, there is a workaround for a sample above (to use 'call echo...' or 'enabledelayedexpansion' commands). But this is redundantly and not "common practice".

From the other side, it's difficult to say, what is common between 'setlocal ... endlocal' and 'enabledelayedexpansion' options. Mean "setting local variables" and "enabling delayed expansion" is logically unrelated functionality.…

# Bloch equations in MRI rotating field

I am trying to understand the workings of an MRI scanner and wanted to figure out how to simulate it by solving Bloch equations in the rotating frame of reference.

I have a small query regarding the apparent Larmor frequency in the rotating frame of reference. So, if $\omega_0$ is the Larmore frequency in the laboratory frame of reference and in the rotating frame the coordinate system is rotating about the $z$ axes with a frequency $-\omega_r$. In this case, now the apparent Larmor frequency would be: $w_{eff} = \omega_0 - \omega_r$.

Now, I have an RF pulse which is entered on the Larmor frequency and has some bandwidth which means that it will excite spins with resonant frequencies +-100 Hz around the Larmor frequency and say I have a slice selection gradient which achieves this frequency difference.

Now, it is clear that for the spins which are in the centre, they will have an apparent resonant frequency of 0 Hz and the other spins would have an apparent resonant frequency +- 100 Hz depending on their position along the z-axes. So, now the time dependent effective field experienced by a spin due to the RF pulse, would this be something like:

$$B_x(t) = rf(t) \cos(2 \pi \omega_{eff} t + \phi_{rf}) \\ B_y(t) = rf(t) \sin(2 \pi \omega_{eff} t + \phi_{rf})$$

Here $rf(t)$ is the amplitude of the rf waveform at time $t$. $w_{eff}$ is the apparent resonant frequency in the rotating frame of reference for a given spin and $\phi_{rf}$ is the phase of the applied RF field. I am not sure if this is correct and wanted to verify.

I am not sure if this should belong to the physics forum but I never get any answers there regarding MRI. But please feel free to migrate if this is not appropriate here.

• It looks good. Isn't there a reference that you could also check? I suppose this is part of most/every textbook.

# Why does Friction act Parallel to the Surface (Microscopic Level)?

If we assume an object (blue layer) sliding towards the right across a surface (black layer). According to Newton's 3rd Law, the frictional force would act to the left (resisting the object's relative motion).

To prevent confusion (as this could lead to one). Imagine a simple inclined plane and a box sliding down due to its own Weight, we know that the force acting on the Plane is the force component that is perpendicular to the Weight, and in accordance to Newton's 3rd law, the box would experience the same amount of force but opposite in direction (which in this case is known as the Normal Force.)

Now moving on to my main problem. The white arrows I drew are perpendicular to the surface of the tiny ridges/asperities (black layer), which also indicates these are the components of the 'pushing' force (red arrow) that would actually act on the ridges, and the pink arrows (equal in magnitude but opposite in direction) are the resistive/reaction force that the object (blue layer) would experience.

Looking back at the direction of the arrows, I notice that they are not opposite to the direction of the object's movement. At first I thought this a contradiction to what is usually told that friction acts opposite to the sliding motion, but using the inclined plane analogy, assuming the weight to be the 'pushing force' and the frictional/resistive force I drew & explained as the 'inclined plane's normal force, which aren't also opposite to each other, this makes sense and therefore Newton's law isn't violated.

Now the question is, Why do we assume the frictional force to be acting exactly opposite of the object's relative motion?

*I might be too 'microscopic' but what I think might be the reason for this is probably, when all these different-directional frictional forces for every ridges/asperinties are 'averaged', it's direction would be very close to being opposite of the object's motion. Thus for simplicity sake we all assume it to be just opposite. Can anyone verify whether this is true? And if not, please kindly correct me. Any clarification would be very helpful.

• Why do we assume that the friction force magnitude is proportional to the normal force magnitude? – BioPhysicist May 29 '19 at 11:49
• I didn't say anything about the pink arrows. I'm asking you a question that you should think about. It might help you with this one. – BioPhysicist May 29 '19 at 15:38
• According to F=u.N , they are indeed proportional. Is this enough? Or should I elaborate more (it might be too long) – user226894 May 29 '19 at 16:05
• I'm not asking you because I don't know and need you to tell me. I'm asking for your benefit. Why do we use that formula? Where does it come from? The exploration of this will help you here. – BioPhysicist May 29 '19 at 21:25
• @aditya_stack Assuming a purely horizontal force of $F=\mu N$ for kinetic friction is a very simplified model. If any object were actually moving across a bumpy/jagged surface, you would not expect the vertical force components to always cancel out as the object slides across the surface. The simplified model neglects this. – BioPhysicist Dec 29 '19 at 18:55
