COMMUNICATION Automatic meter reading is the technology of automatically collecting consumption‚ diagnostic‚ and status data from water meter or energy metering devices (gas‚ electric) and transferring that data to a central database for billing‚ troubleshooting‚ and analyzing. This technology mainly saves utility providers the expense of periodic trips to each physical location to read a meter. Another advantage is that billing can be based on near real-time consumption rather than on estimates

THE INTRODUCTION TO SOAP MANUFACTURE BY W. H. SIMMONS‚ B.Sc. (Lond.)‚ F.C.S. AND H. A. APPLETON It has been said that the use of soap is a gauge of the civilisation of a nation‚ but though this may perhaps be in a great measure correct at the present day‚ the use of soap has not always been co-existent with civilisation‚ for according to Pliny (Nat. Hist.‚ xxviii.‚ 12‚ 51) soap was first introduced into Rome from Germany‚ having been discovered by the Gauls‚ who used the product obtained by

PREPAID ENERGY METER The present system of energy billing is error prone and also time and labor consuming. Errors get introduced at every stage of energy billing like errors with electro-mechanical meters‚ human errors while noting down the meter reading‚ and errors while processing the paid bills and the due bills. There are many cases where the bill is paid and then is shown as a due amount in the next bill. There is no proper way to know the consumer’s maximum demand‚ usage details‚ losses

"My opinion is‚ that power should always be distrusted‚ in whatever hands it is placed. (Sir William Jones‚ 1835) The theme of power is addressed in different ways in each of the two plays. The title of Shakespeare’s play‚ ’Measure for measure’ is an indication for the audience of the possible themes and makes an allusion to the old testament teaching ’an eye for an eye’ (Leviticus‚ 24:20) and also conjures the mental image of a pair of scales‚ with each ’measure’ or action done weighed up and

Evaluation Evaluation Experiment one: This experiment was quite accurate‚ as when it is compared to the manufactures line which is on the same graph‚ we can see that this line is at most only 0.4? different form the manufactures line. This is a percentage difference of approximately 8%‚ using the formula: Difference ? original X 100 This shows that the results were good‚ as 8% is a very small margin of error. The error bars on the graph show that the most inaccurate result was the 60cm result
