f the technological supervision department. Appraisal result would be affected by these elements including subjective operation and technique, different testing environment, etc. which possibly result in additional error.Pay much attenti fuel dispenser on to the following items: Maximum measuring valve and accuracy of standard measurer The cubage and volume of metal standard measurement used for fuel dispenser appraisal has regulated in procedure and regulation. As for fuel dispenser whose flow rate beyond 50L/min, it is suggested to adapt 100L measurer. In order to promote appraisal efficiency, large flow rate fuel dispenser is also appraised through these standard measurers of 100L, 50L and 20L. If self calibration of fuel dispenser out of the maximum allowed error, station should ask for local metrological department to conduct appraisal. Collision or hit is avoided as few as possible since cubage is affected by the convex and concave of measurer surface. Vernier of measurer is fixed on measuring neck. Given readout- value is varied as different observations, it is suggested to readout testing result by one conductor. Measurer should sent to technolog fuel dispenser ical department and be appraised periodically. Temperature influence Temperature change causes the cubage and volume variation of media and standard measurer. Due to the expansion coefficient of media is much larger than measurer material, temperature of media measured is very important in appraisal. 1�errand would lead to 0.1% relative cubage error. Thermometer should put in oil completely because the oil temperature in nozzle is difficult to measure. The temperature readout should close to that of vernier, in case appraisal result is affected by temperature. Flux influence The indicating value of same flow meter is varied under different flow ra fuel dispenser te according to the error characteristic of cubage flow meter. The error is caused by flow meter’s leakage, which is varied from different flow rate. Thereby, openness of nozzle should keep stable in appraisal progress

are large numbers and are the intermediate values sent across the　　 communication link encrypted under a default DES key. Knowledge of a q R　　 S and even the default DES key is not suffi fuel dispenser cient to discover r s or KD.　　 Note that the KD value is different for every COPT in the site because it is based on　　 random numbers r and s and is different every time the calculations are　　 performed even if by the same COPT. The latter facilitates replacement of a suspected　　 compromised key.　　 To break this method requires an iterative approach and boils down to which value of　　 r in the calculation mod q(a to the r) produces R . In addition to discovering　　 r a successful penetration would also have to discover s .　　 The KD is then manipulated by the Function f() to produce a DES key which we term　　 the Key Exchange Key (KEK). The KEK is used to encrypt and decrypt derivation　　 keys which are shipped from the controller to the fuel dispenser COPT to be used for DUKPT　　 operation.　　 Below are the exchange sequences needed to initialize the COPT and to send　　 encrypted data to the controller.　　Key Exchange Sequence　　 COPT CD　　1.

g, with too many of their students from deprived backgrounds. For example, at Wilson Senior High, a school perched on a hill above blue-collar East Los Angeles, the academic year started with well over 3,000 students. There are now arou fuel dispenser nd 2,800 (the number fluctuates as families move in and out of the district) of which some 93% are Latino, 5% Asian and just over 1% black. Only one in 200 is a non-Hispanic white. Factor in poverty (three-quarters of the students qualify for free meals) and family backgrounds in which English is often an unknown language, and academic excellence becomes an improbable target. Add, too, the need for those Wilson students who come from central Los Angeles to get up in time for a school bus at 6.30am. Or the need to cope with pupil pregnancies (expectant mothers study in a separate annexe). Or endemic problems with drugs and gangs. No wonder, whatever the efforts of the 130-odd teaching staff, that only 29% of the students last year met the federal criterion for language and arts proficiency, and that in maths the proportion was just under 20%. It is perilously easy for any student, clever or dim, to fa fuel dispenser ll by the wayside. And the same holds true in many more of the district s 858 schools, from the 431 elementary schools to the 53 senior highs. The challenge, familiar to big-city leaders across the country, is to do something about it. Mr Villaraigosa s solution, announced last week, is to seek approval from California s lawmakers for a council of mayors from all 28 cities that fall within the LAUSD. As early as January the council would have the power over a six-year trial period to “wake up and shake up the bureaucracy at the LAUSD� in particular by encouraging charter schools, which are free of the district s direct control. In other words, t fuel dispenser he elected school board will have its wings severely clipped and Mr Villaraigosa—because power on the mayors council will be proportional to each city s population, and LA students make up 80% of the LAUSD—will
