the report noted that the forces that drive electronic commerce will require a re-examination of the framework for conducting business and a questioning of both the efficacy of government policies pertaining to commerce and of traditional commercial practices and procedures, most of which were formed with a much different image of commerce in mind.
وأشار التقرير أيضا إلى أن القوى التي تقود التجارة الإلكترونية سوف تتطلب إعادة النظر في الإطار الذي يتم فيه القيام بالأعمال التجارية والتساؤل عن فعالية السياسات الحكومية المتصلة بالتجارة وفعالية الممارسات والإجراءات التجارية التقليدية، ومعظمها نشأ وفقاً لصورة مختلفة جداً عن التجارة في الأذهان.

advanced ac motors obviously it should be as efficient as possible, and it would be desirable to be able to run it at varying speeds depending on the required load . with its miserable efficiency and lack of enthusiasm for running at anything but one particular speed , a single-phase induction motor is a poor _ if inexpensive_choice. many modern airconditioners therefore instead use "inverter" technology. what this means is that they rectify the mains to create dc, then use an inverter, or dc to ac converter, to go back to ac again . however, the ac that is produced is no longer at 50hz , but is at a variale frequency. even if we just used a conventional induction motor now we 'd be ahead, because we'll be driving it at the optimum frequency , and hence rotational speed, for the required load. however, we can go one better than this and use a switched reluctance motor (which has a rotor made from soft iron) or a brushless dc motor (which has a permanent -magnet rotor), and achieve even higher efficiencies. it is one of the strange perversities of life that we will now call a dc motor , even though it's quite decidedly running off ac ! advantages: . can be optimised for task .can be much more efficient . can run at variable speed . can last forever disadvatages: .expensive (relative to a induction motor) . requires complex drive electronics .takes longer to explain than simple motors
