    A novel substitute for the meter readers in a resource constrained electricity utility
    (© 2010-2012 IEEE., 2013) Ahmed, Shahnawaz S.; Hussain, Shah Muhammed Abid; Salam, Dr. Md. Sayeed
    A novel scheme has been proposed where the consumers will use their mobile phone cameras to take the photograph of respective meter's display panel along with the kWh (kilo-watt hour) information once a month and send it as an image to the utility servers using the MMS (Multimedia Message Service) from their mobile phones. The server will process the image, retrieve the kWh information, convert it into a text (number) and archive it against the consumer's mobile number or identity code. The way this can be implemented is illustrated.

    Modeling the energy consumption of a lift
    (© 2014 Elsevier B.V., 2014) Ahmed, Shamsuddin Shahnawaz; Iqbal, Asif P M; Sarwar, Rashed; Salam, Dr. Md. Sayeed
    A semi-rigorous and generalized model has been developed to determine the electrical energy (Watt-hour) consumed by the motor of a typical lift in each step of an upward or a downward travel cycle. The model has been validated comparing its output with the actual readings taken from an energy meter (installed at the terminal of the motor) for several cycles of the traffic according to the existing route map for a real-life lift. The developed model can be used as a decision support tool by the energy managers of high rise buildings to revise the route map of a group of lifts time to time depending upon the needs. With the model they can simulate intended variations in the floor and traffic plans and compare their impacts upon the energy consumption. As an example the developed model has been demonstrated for the system of three lifts located in the 20 storied main building of BRAC University.
