From 2009 Formula 1 teams have the option of employing a KERS to boost their car’s performance. As its name implies, a KERS recovers the (normally wasted) kinetic energy generated by the car’s braking process. This energy is stored using a mechanical flywheel or an electrical battery and then made available to the driver, in set amounts per lap, via a ‘boost button’ on the steering wheel. Under the current regulations the power gain equates to around 80 horsepower, available for just under seven seconds per lap. This could be worth several tenths of a second in terms of lap time, but the weight and packaging of the system – and its impact on the car’s weight distribution – also have to be taken into account.
KERS layout and functionality – charging phase
Kinetic Energy Recovery Systems, or KERS, become optional for 2009. Such systems take waste energy from the car’s braking process, store it and then reuse it to temporarily boost engine power. This and the following diagram show the typical placement of the main components at the base of the fuel tank, and illustrate the system’s basic functionality – a charging phase and a boost phase. In the charging phase, kinetic energy from the rear brakes (1) is captured by an electric alternator/motor (2), controlled by a central processing unit (CPU) (3), which then charges the batteries (4).
KERS layout and functionality – boost phase
In the boost phase, the electric alternator/motor gives the stored energy back to the engine in a continuous stream when the driver presses a boost button on the steering wheel. This energy equates to around 80 horsepower and may be used for up to 6.6 seconds per lap. The location of the main KERS components at the base of the fuel tank reduces fuel capacity (typically 90-100kg in 2008 ) by around 15kg, enough to influence race strategy, particularly at circuits where it was previously possible to run just one stop. The system also requires additional radiators to cool the batteries. Mechanical KERS, as opposed to the electrical KERS illustrated here, work on the same principle, but use a flywheel to store and re-use the waste energy.
Q: How do I restart the spool work process without restarting the SAP application?
A: You can use the transaction SM50. Choose the spool work process then select “proces–>cancel without core”.
If you selected “restart after error–> yes”, workprocess will be restarted and you will see the the error colon will get a red status.
Q: Can I switch other work processes to spool work processes without restarting the instance?
A: No. The internal structure of spool work processes is different from, for example, dialog work processes. Therefore, if you want to change the number of spool work processes, you must do this in the context of SAP profile maintenance (transaction RZ10) and then restart the instance.
Do you know Doraemon? yeach, it’s comic character created by Fujiko F. Fujiya (if i’m not mistaken), Japan’s comic writer.
I read this comic since I was 10 years-old.
As you know, Doraemon is a story with no ending, but this small story is about the “last episode” of the famous cartoon.
Someone made this story (finally I know the name, Nobuo Sato) and uploaded it to his homepage, and it is now widely spread all around Japan through the internet.
Here it goes. Happy reading 
===============================
One day,a very normal day, Nobita came back from school and went upstairs of his house. Doraemon was there sleeping, just like the other normal day.
“Hey, Doraemon, please wake up, lets play!” but Doraemon does not wake up.
Nobita thought that Doraemon is tired, so he went out to play with Shizuka-chan and other folks. After few hours, he returned to his home, but Doraemon was still sleeping. Nobita felt something strange, and tried to wake him up. But there was no reply. He became to feel afraid, and tried to wake him up, but whatever he does, Doraemon did not wake up.
Nobita exactly knew that something was different. This never happened before. He began crying, but though he screamed or cried, the famous fat-cat-robot did not make a single move at all. He came up to one idea, and jumped into his desk-the time machine-and went to the future to meet Dorami-chan, Doraemon’s sister. He begged her for help, and forced her to go with him back to 1998.
After a short trip again back to 1998 by the time machine, Dorami-chan looked all over his brother Doraemon to see what was wrong with him.
After few minutes, she said “the battery is out”. Nobita was relieved, and said,”battery? so he is not broken right? please replace or recharge his battery, and put him back like before”.
But Dorami-chan shook her head and said,”Nobita-san, should I really do that?”.
Nobita said “what? what do you mean?” Dorami-chan replied; “His main battery is here, close to his pocket. And it ran out. But originally, he had a back-up battery in his ears, but as you know, his ears were eaten by a rat very many years ago, so he does not have a back-up battery now”.
“so what do you mean?”.
“I mean, if I replace his battery, every memory of you will be eternally lost from his brain program”.
“WHAT?????”
“Shall I do that?”
Nobita closed his eyes. He cried, but after few minutes, he stopped crying,and quietly told Dorami-chan.
“Dorami-chan, thanks for coming here. I will take care of the rest. You have to go back to your future time now”.
Dorami-chan could not decide what to do, but anyway she hugged Nobita quietly, and she went back home. After she went back,Nobita carried Doraemon and placed him into the shelf.
………TIME FLIES……….
Year 2010, Nobita grew up. Since that day, he changed.
He studied hard, did not cry anymore, and he lived without Doraemon. He told Shizuka and other folks that Doraemon had to go back to his future, and could not meet him anymore. Shizuka was impressed to Nobita’s mysterious appearance which became completely different from 10years ago.
They fell in love, and married. Nobita became a scientist. He made a laboratory in his room, and was studying hard with his job all day. He told Shizuka not to come into the room, as it is very dangerous inside.
But one day, he called Shizuka and told her to come in to his room. It was the first time for her to enter her husband’s room. The moment she went in, she lost her words.
…..There was her friend Doraemon, who she used to play in her childhood days.
Doraemon was not moving. It seemed as he was sleeping.
“Look, Shizuka, I will plug in from now”.
Nobita turned on the main switch on Doraemon. Doraemon quietly, very quietly started to open his eyes. It was the moment the inventor of Doraemon became clear. It was Nobita. He studied hard and hard just to meet and talk with his old friend again. Going back and forth of time, Nobita was the one who made Doraemon. He discovered all the programs and architecture of Doraemon-type-robot.
Nobita and Shizuka was crying gently.
Doraemon opened his eyes. He looked around, and finally said,
“Nobita-kun, did you finish your homework?”
There was the same white clouds in the sky like the times they used to spend together.
==============================
Note:
- The above story was made by Nobuo Sato
- The comic is captured in Bahasa version (just because I didn’t find the English version )
- Nobita, the lazy boy who always cries and depends on Doraemon, finally studies hard, becomes a scientist, to repair and save his best-friend.
It’s so awesome, affectionate.
As of SAP Web Application Server 6.10, SMTP (Simple Mail Transfer Protocol) is supported directly by the SAP kernel. This means that it is possible to exchange e-mails between the SAP system and any SMTP-compatible mail server without using additional external components (such as connectors or gateways). You can use any product that meets the SMTP standard as a mail server.
As of SAP Web Application Server 6.20, it is also possible to exchange faxes and text messages (pager/SMS) using SMTP. Faxes and text messages are packed into e-mails for this purpose.
Further explanation can be showed here.
