hi dear ones,

Challenges for Embedded Systems                                        

             The New World of pervasive computing, with millions of computers virtually everywhere, brings new opportunities but also new problems. On a system level, the most important challenges are how to develop and manage the software system, while guaranteeing sufficient quality at acceptable cost.  but which deserves an increased attention to match the problems encountered by industry.

                    The main problem (and strength) with software (compared to hardware) is its flexibility and that it is not governed by any natural laws, except timing. Traditionally, methods that for certain classes of systems can provide timing and Reliability guarantees have been developed. These methods need to be extended and made more generally applicable. Additionally, industry needs research into software and system architectures that can provide appropriate structure, flexibility and infrastructure, while making it possible to guarantee quality at reasonable cost. In several cases this will mean absolute timing and reliability guarantees at virtually no cost.

Specific topics that should be addressed include:

•Correct behavior during the lifecycle. The competitive pressure, together with growing functionality

and complexity of embedded systems, means that such systems cannot be built from scratch each time. Instead, they have to be composed from existing building blocks, often emanating from different vendors. Not only that, as all software systems, they will be updated during their entire lifecycle. These are not PCs where an error causes irritation and often can be corrected with a restart, but systems where an error may have serious and sometimes catastrophic consequences. Research is needed on the dynamic architecture of such complex heterogeneous embedded software systems, as well as on the process on how to build and maintain them.

 

•The updating process. A growing problem, as the number of embedded computers per person increases, is the maintenance of software systems. There will even be many computers in our appliances that we will not be aware of (and do not want to be aware of), but which require updates and downloads of new software. In many cases the software must be updated “on the fly” while the system is running. This is done already today, but much remains to make these updates safe and cheap enough in many applications. The sheer volume, updating thousands or millions of computers, adds to the updating problem. The only feasible way to handle the volume is to do remote updates over interconnected networks, possible the Internet, from specialized management servers.

 

•Safety, security and integrity. Correct behavior is the first condition to achieve safety, security and

integrity. But special mechanisms are also needed. The need for safety in a car or a medical device is evident. In most of the embedded systems a huge amount of information will be handled, information to which there is a great number of “interested parties”. The fight for better security, not the least to guard our integrity, will have to be fought constantly. There are, of course, also important challenges on the microelectronics side, including how to minimise power consumption, weight and cost, together with robust integration of different technologies and with mechanical devices. All the above and several additional technical issues are important to address.  Research/graduate education efforts into embedded systems will not only provide competence in this area, but also provide an increased focus on embedded systems in the entire educational system.

Hi dear ones,

How to Behave at the Dining Table                           

  1. Posture: Sit up straight at the table, never lean backward, nor forward and also never let the elbows touch the table. This makes a good impression. When you are not eating, keep your hands on your lap or rest on the table.
  2. “Please” and “Thank you” are basic manners at the table: Say “Please” when asking people to pass you something and “Thank you” when you receive something.
  3. The best way to use a napkin: The napkin should be placed on the lap to catch crumbs or drips while eating food and should be kept back on the table neatly, after the meal is finished.
  4. Food is passed at a family meal by the head of the family or the host/hostess: It is often passed in a counterclockwise movement around the table.
  5. Wait for others to start eating. In many homes they say a prayer first.
  6. It is best to order foods that can be eaten with a knife and a fork. Finger foods can be messy and are best left for informal dining.
  7. The only way to eat is slowly and quietly. Chew small bites of food and swallow with the mouth closed.
  8. Smoking should not be done while dining out.
  9. One should avoid touching nose, teeth and combing hair while dinning.

10.  The table and tablecloth should be kept clean. Do not put bones or any other morsels on the table.

11.  Avoid spitting anything out. If there is something in the mouth, which can’t be swallowed, quietly put it in a paper napkin and then continue. (e.g. bones, seeds, etc.)

12.  End the meal properly. When a person has finished eating, the fork and the knife are placed diagonally crossed across the plate, this is the best way to inform the server that you have finished eating.

13.  When you have finished eating, express appreciation for the meal. You can perhaps say “What a delicious meal! Thank you so much.” And then wait for all to be finished before leaving the table.

To handle some of the unfortunate and embarrassing moments while eating food, following are some tips:

  1. If some beverage or food is spilled on some guest while eating: The best way is to handle the situation with a calm and quiet frame of mind. Apologize first and then using the cloth napkin and water wipe it gently or else gently guide the guest to the wash room.
  2. When a bug appears: If a bug or anything of that sort appears in your salad etc. quietly send it back but do not point it out because it might ruin the entire dinner for the rest of the people.
  3. To remove a distasteful food item from the mouth: The food should be removed in the napkin discreetly and the food morsel should be kept out of view from others.
  4. If a piece of silverware falls onto the floor: It should be picked up if one can reach it and the server should be told to replenish it with a clean one.
  5. Some food items can be eaten with fingers: Some food tastes better when eaten with fingers. So you can eat with your fingers provided you use just the first two segments of the thumb, the index and middle fingers to pop the food into the mouth. Avoid licking fingers after finishing the food. Food should be always eaten with right hand.

we are ready to eat now.
