In present world almost all industrial systems are based on wireless communication, as it has many advantages. The development of a fully Automated Energy Meter which is having capabilities like remote monitoring and controlling of energy meter will lead to transparency in the energy meter reading and billing system. This system avoids the human intervention in power management. If the customer does not pay the bill in time, the user is informed through SMS system using GSM. If still customer does not pay the bill then as per designed late consideration, one alert message will be sent then automatically the power connection is disconnected from the remote server. The purpose of this project is the remote monitoring and control of the domestic energy meter; its aims includes: to design a circuit which continuously monitors the meter reading and sends message to electricity company, programming of the GSM MODEM with AT (Attention)command sequence, interfacing the programmable chip with the personal computer, interfacing the programmable chip with the energy meter, interfacing of GSM MODEM with the programmable chip, sending messages from the remote phone to control device.

A method for determination of selected organophosphorus pesticides (OPs) along with their degradation products in post mortem tissues is reported in the paper. Malathion, Dimethoate and Phorate are frequently found organophosphates in homicidal or suicidal poisoning cases. The separation of these pesticides along-with their oxon degradation products Malaoxon, Omethoate and Phorate-sulfone respectively is achieved by a programmed temperature capillary column gas chromatography coupled with a nitrogenphosphorus detector (NPD). Prior to analysis, pesticide residues were extracted by QuEChERS extraction method. Matrix matched calibration curves were linear with coefficients of correlation better than 0.995 for concentration range from 0.5 to 20 μg/gm while the limits of detection ranged from 0.05 to 0.85 μg/gm for all compounds. The method is simple, rapid and was used to detect the oxon degradation products of the original OP which otherwise were not detectable by other conventional methods used for routine analysis of post-mortem tissues in poisoning cases.

The article discusses a comparative study of pounding forces obtained from several models of impact simulation. Topics covered include pounding models' uncertainty in collision properties that alter a structure's final response, damage resulting from pounding between adjacent structures in densely populated cities, and the mathematical formulation of gap element spring properties. The linear single degree of freedom (SDOF) system in each adjacent structure in a system is also mentioned.

The optimum parameters of multiple tuned mass dampers (MTMD) for suppressing the dynamic response of a base-excited damped main system are investigated by a numerical searching technique. The criterion selected for the optimality is the minimization of the steady state displacement of the main system under harmonic base acceleration. The parameters of the MTMD that are optimized include: the damping ratio, the tuning frequency ratio and the frequency bandwidth. The optimum parameters of the MTMD system and corresponding displacement are obtained for different damping ratios of the main system and different mass ratios of the MTMD system. The explicit formulas for the optimum parameters of the MTMD (i.e. damping ratio, bandwidth and tuning frequency) are then derived using a curve-fitting scheme that can readily be used in engineering applications. The error in the proposed explicit expressions is investigated and found to be negligible. The effectiveness of the optimally designed MTMD system is also compared with that of the optimum single tuned mass damper. It is observed that the optimally designed MTMD system is more effective for vibration control than the single tuned mass damper. Further, the damping in the main system significantly influences the optimum parameters and the effectiveness of the MTMD system. [ABSTRACT FROM AUTHOR]
