communication vocale. Mais comme le besoin se faisait sentir, ce débit a été insuffisant pour le transfert de fichiers, d’images, de vidéos, accès à Internet et autres. Pour palier à ce problème on a évoqué la technique HSCSD (High Speed Circuit Switched Data) qui permet d’utiliser 2, 3 …6 time-slots du GSM avec un débit de 14,4 Kbits/s par time-slot (avec protection réduite contre les erreurs). Théoriquement on peut atteindre un débit de 64 Kbits/s elle n’a pas connu beaucoup de succès et elle

liquid over it. 2. Electrical hazard Important: only maintenance technicians approved by the manufacturer are authorized to open and/or dismantle the machine. 3. Moving the machine The machine should not be moved when operating mode even switched on. 4. Installation conditions The machine is intended for indoor use only. Site requirements: 1. The machine should be installed near a main electrical outlet which should remain accessible after the installation so that the user can disconnect

200kg. The creator of Big Ben is Benjamin Hall who gave the nickname to its creation: his nickname was Ben, and, as it was a little bit corpulent, we also called Big. That’s why the big clock is called Big Ben. The light above the clock is lit (switched on) when the parliament sits. [pic] [pic]

saves the first and most expensive years of retirement. After a hard strugle with the governemt early retirment before 65 remains with the use of all fiscal posiblities, possible. A majority of the Dutch pension funds have according to our policy, switched from final pay to average pay Systems. These system makes the risks on the liability side of pension funds’ balance sheets better manageable. This relates to the fact that average pay systems are not susceptible to ‘career back service costs’, since

the peto tube and noted so the dynamic pressure can be calculated. we can so observe the rise in temperature on the PC logger software. After the temperature is reached the logger software is stopped and the experimental data saved, the wind tunnel switched off and the rod removed from the test section. This procedure is then repeated another 5 times, each time reducing the percentage of air flow by adjusting the orifice plate appropriately. The percentages of air flow used are 100%, 84%, 69%, 60%,
