Hello, my name is Marat and you're on Amyntas channel. Very little is left before the new 2017, and as you may have guessed, this is the last issue of this year.
In my life, a lot has happened in the 2012th. There were sad moments and happy, but on the whole this year has brought me a lot of good
You know sometimes you're so happy that the year is over, when you are pursuing a series of misfortunes disappointments, betrayals.
You blame with the 2011, 2012, 2016, and believe firmly in the fact that it is next year will bring you happiness.
Support and continuous personal growth, that is what we should strive.
Be smarter, wiser and kinder. Do what you're doing, inspires it all around, do not be afraid to once again smile and sad man assumed a cheerful face at the small child
It is not a shame! I am ashamed to behave like a shit to thump at the door and endlessly complain about their lives, while not trying to change anything.
Get yourself together and live. Live itself, inspiring environment, even if you're doing something that others do not support, but you keep going after one soldier in the field, because the revolution begins with one person
Every year, to develop all over, lifts up above the bar as soon as the previous touched, become a better version of yourself. And the most important in the world of life hacking
And so in 2017 on its way. We are preparing a major social project called Being Human, which will publish in January 2017 July. Subscribe to this channel that would recognize all of the first to bring friends together and let us do good to all.
Do something for which to be ashamed, neither the parents nor the children before. Happy New Year my friends! Find your happiness and live this year so that he used to complain.

7 - MAC Scheduler & Physical Channels - Fundamentals of 4G ( LTE ) - Duration: 9:24.
Hello Friends, Welcome back to the world of 4G.
Today we will discuss the function MAC Scheduler Module and Physical Channel.
Previously We have shown, The different functions of MAC layer, With the analogy of transportation
mechanism used in logistic companies.
In addition to that, MAC layer also contains MAC control, which performs 2 important operation.
1. As we know, during transmission and reception of data, a lot of power is consumed by the handset
So, in order to save power, the user equipment does not stay awake all the time.
In Idle mode, It wakes up at fixed intervals, to receive data through paging alert messages.
This is called Discontinuous reception or DRX operation.
now, this paging alert messages are neither processed by MAC layer, nor by Hybrid ARQ layer
since, Paging signals are retransmitted on fixed intervals, based on Discontinuous reception
or DRX inactivity timer.
So it does not depend on HARQ Ack/NACK response.
2. MAC control is also responsible for the alignment of the uplink timing and power headroom reporting.
The most important function of eNB, is to allocate resources dynamically.
This function is handled by MAC scheduler module of MAC Layer.
Previously we have discussed that MAC layer has to handle,
1. HARQ retransmission control,
2. Logical channel multiplexing and priority handling.
These functions are actually handled by MAC scheduler module.
In addition to that it has to- Dynamically Decide Modulation scheme-
The MAC scheduler gets information of the Instantaneous Radio channel quality from Users through
Channel state information message in which it sends the CQI.
Based on channel quality it decides which modulation scheme is to be used.
Now, The data in DLSCH or user plane channel contains user traffic which needs to be carried out
to Users irrespective of channel quality outside.
If the coverage is poor the network will use QPSK.
Else it will use higher Modulation schemes such as, 16QAM, 64QAM etc.
But the signalling channels need guaranteed delivery that is why they use QPSK as it is
considered the most ROBUST modulation scheme.
MAC scheduler module also has to decide, Which are the terminals to transmit.
The set of resource block upon which the downlink shared data for the mentioned terminal would delivered.
The selection of transport Block size.
These 3 functions are implemented in Physical layer.
So, as you can see, MAC scheduler module takes most of the decision.
Rest just follow accordingly.
That is why it is also called as the "Brain of LTE".
That Brings us to our last and most complex part, that is Physical Channels.
The transport channels such as Paging Channel and Downlink Shared Channel, are mapped into
Physical Downlink Shared Channel.
It is used for carrying user traffic and as well Paging information.
The Broadcast Channel and MultiCast channel are mapped one to one Physical Broadcast Channel
and Physical Multicast Channel.
Similarly in UPLINK, The transport channel such as Uplink shared
channel is mapped on to Physical Uplink Shared Channel, and Physical Random Access Channel
is used for random access functions.
Now, consider you are an user, you received some physical data from eNB, through physical channels
But you don't know in which Resource element, the Downlink shared data is hidden or, which
demodulation scheme to be use.
That is why L1 and L2 control signals are used.
They carry Downlink Control information, which contain relevant information on how to process
the physical data.
It is just like the record submitted by team Z, based on which the items are extracted
at receiving end.
The various Control signals used here are, Physical Downlink Control Channel: This channel
carries, the control information about the data being transmitted on the current subframe
and the information about the system information block, which User need to use for the transmission of uplink data
That means it is mandatory for the User to decode it successfully if it wants to send
some data or receive something.
It also provides Uplink Power control information and Hybrid ARQ info.
Physical Control Format Indicator Channel:- As the name implies, these channel informs
the user about the format of the signal being received.
It indicates the number of OFDM symbols used for the PDCCH, whether 1, 2, or 3.
The information within this channel is essential to decode PDCCH, because the user does not
have prior information about number of resource to be used in OFDM Grid.
Physical HARQ Indicator Channel:- It carries the HARQ ACK/NACK signal, indicating whether
a transport block has been correctly received.
The Control signal used in UPLINK is Physical uplink control channel, which is the counterpart
of PDCCH in downlink.
If we notice here, There are no Transport channels corresponding to Control Channels/Signals.
So far, we have seen the function of Logical, Transport and Physical channels.
But these MAC PDUs or the Transport Blocks, which are being delivered from MAC Layer to
the Physical Layer undergo a lot of Digital Signal Processing before being sent to the
air interface as RF signals.
Let us understand them with the help of Block Diagram.
CRC attach - A cyclic redundancy check (CRC)added to every transport block for error checking.
If after Adding CRC to the transport block exceeds the maximum block size, then it is
segmented to smaller code blocks, and individual CRC is added to each code blocks by a
Turbo coder, which is called as code block segmentation.
Channel coding - It's a turbo coding step, whose job is basically converting one bit
input to 3 bit output as it goes through the turbo coding processor (It means the coding rate is 1/3).
Rate matching - In simple words, the output of the Turbocoder goes through detailed process
of "interleaving", "BitCollection", "Bit Selection and pruning" and ultimately generates an encoded
bit stream
these coded streams then go through scrambling process, after that they are mapped to correct
modulation scheme which is decided by MAC scheduler, as discussed earlier.
After a precoding process, finally the bits are mapped to Resource elements and then goes
for OFDMA process.
In Uplink the same physical layer model is used only the last OFDMA block is replaced
by SC-FDMA.
Once the signal processing is complete, the resources are finally ready to be transmitted
in AIR interface.
That brings us to the End of Channels used here.
To summaries it all- Logical channels tell WHAT is the type and purpose of the Data.
Such as paging, broadcasting etc
Transport Channels decide HOW the data is going to be transmitted.
It allocates the transport block size and dynamically decides the modulation scheme
that is to be used.
Physical Channels know WHERE exactly the Resource elements are located.
It handles the Signal Processing and thus it knows HOW EXACTLY the data is going to be transmitted.
So In a nutshell we can say, We cannot transmit the data without knowing
WHERE to transmit and HOW it should be transmitted, also we cannot decide HOW a data should be
transmitted without knowing WHAT is the data.
So in hierarchy of 4G protocol stack. first LOGICAL, then TRANSPORT, Then PHYSICAL.
So Friends, Thanks for making it to the end.
In our next video we will be discussing MIMO(Multiple Input Multiple output) and Carrier Aggregation
where we will also discuss how Throughput is calculated.
You can post your doubts in the comments section.
Don't forget to share it with your friends.
:) HAPPY LEARNING :)

【DIY】Installing a Pegboard ☆ 有孔ボードを取り付けてみた！ - Duration: 5:39.
There's one thing I haven't done yet for over a year.
I'm gonna get it done today and already bought some materials.
Let's do some DIY.
I guess it won't take long time.
or perhaps I shouldn't call this DIY.
what's this?
There's a hole.
the size is 600mm by 900mm.
the distance between these holes is 25mm.
I think it's 5mm thick.
considering the price, this board is kind of cheap than I expected it to be.
It seems they didn't do anything after cutting the edges. maybe I should file the edges.
and these corners. they might cut this by hand.
Each corners look different.
This is the metal fittings that came with.
but the package says this is designed for gypsum board walls.
Can I use screws to fit this?
These are the pegs I bought. I'll open it later.
This is the best screw I could find in my house.
apparently this is not the best choice, but use this and see what happens.
Can I fix this?
doesn't matter.
What I want to hang up with these pegs is...
I don't use this often though.
yeah, these tools.
I usually put them into this basket.
It's always kind of the pain in the neck to take tools out.
I thought it's gonna be great to hang up just like this.
that's the reason I bought these. let's do it.
I changed the position a little bit. and this is how it looks now.
I might change the position as I use this.
It's really great to have screwdrivers near my desk because I use them quite often.
Next DIY would be the whole working table here.
But I don't know if I have enough time to do it though. so please wait without any expectations. see you!

English Rhymes For Children | Autumn Songs For Kids | Nursery Songs | Rhymes For Kids - Duration: 3:14.
Red and yellow
Orange and brown -
Autumn leaves
Falling down
Here a splash
There a crush
I jump about
In autumn colours..
A windy rush,
Leaves all lash
In wavy spells
They all crash
Here I run
Here I fly
Like a little bird
In the autumn sky..
Like a little bird
In the autumn sky
One by one
Colours rustle
From sky to earth
Twirling leaves
Here I jump
Beneath the trees
I dance in glee
With the autumn leaves!
Dance in glee with the autumn leaves..
Here I fly like a bird
In the autumn sky..

Ya Me Enteré - Reik (Francesca Aservi Cover) / English Subtitles - Duration: 3:32.
Hi! my name is Francesca,
today i´m going to sing "Ya me enteré" by Reik
it´s a song i like very much
and that i have always wanted to cover,
but i haven´t been able to do it
so today i´m going to do it! today i had time
so i will record it
i have made some changes in the lyrics,
because originally this is a song sung by a boy to a girl
and i´ve made a short adaptation
actually i have only changed some words
i hope you like it!
(Lyrics) I found out
That there's someone new caressing your skin
Some idiot that you want to convince
That you and I… We're over.
I found out
That I'm the villain and the whole world believes you
That you're better off now that you don't see me
Happier with another by your side
Who do you think you're going to fool?
You know well, that you are my other half…
Forget about that new love
And tell him that I'm better
That you're not faithful with heart
That you're mine and only mine, love.
forget about that new love
Who imagines that I no longer exist
Make it clear that even if he tries, no
You're not going to love him, no
The truth is, you miss me too much
I know it
I found out
You'll come back...
I'm sure you'll come back
You're with her purely for comfort
But yet bored in her arms…
Who do you think you are going to fool?
You know well, that you are my other half
Forget about that new love
And tell her that I am better.
That you are not faithful with heart
That you're mine and only mine, love
Say goodbye to that new love
Who imagines that I no longer exist
Make it clear that even if she tries, no
You're not going to love her… no
The truth is, you miss me too much
I know it…
I found out
I found out
