In this modern era, the influence of technology is more crucial and critical. The technology provides luxury to the society and at the same time technology’s negative effect also affects the society adversely. All the aspects of drone technology are challenged: its innovation, validity, ethics, effectiveness, and future expansion. The capacity is to stay for the long haul, and we should deal with the difficulties it conveys and we have to exploit its military and civil applications. This paper reviews a retrospective on the United Arab Emirates aviation policy on drones. It also examines aviation safety; aviation security; identifies emerging issues in drone’s technology; mitigating the negative side of drones and the strategic effects of a lethal drone policy of United Arab Emirates.

Heat Exchangers (HEs) are used widely in industries where transfer of heat between two or more mediums is a necessity. The fouling of a heat exchanger is a natural phenomenon and depends upon various factors like fluid - velocity & composition, working temperatures, material of HE, flow geometry, etc. The various fouling reduction techniques are being used in Industries for increasing the performance of the HE. The present paper utilizes the methodology prescribed in the available literature for prediction of Net Transfer Unit (NTU): clean and fouled values, for predicting corresponding clean and fouled Effectiveness. The predicted fouled and clean values of effectiveness compare to the corresponding measured effectiveness of a heat exchanger. The real time operational parametric trending is taken from the available literature for A unit HE of Urea process plant for Nortore Nigeria Plc. The imbibed parameters were used for predicting "Predicted Clean" and "Predicted Fouled" and calculating "Actual Measured" effectiveness of the HE, for a span of ten weeks before maintenance and, ten weeks after maintenance. Thereafter, using "Predicted Clean", "Predicted Fouled" and "Actual Measured" values of effectiveness, Index of fouling "IF" has been calculated for complete twenty weeks of operation of the unit. The IF values confirmed high fouling for the first ten weeks of operation and therefore heat transfer rate was also lower than the design value. The plant undertook a maintenance post tenth week of operation when the heat transfer rate was minimum i.e. 9778.4 W. The calculated value of fouling index has been found to be the maximum during the tenth week, indicating fouled HE. The trend between the heat transfer rate and IF shows close compliance during both before and after the maintenance period

In this paper, we have contrasted with assessing four diverse parallel calculations, for the all-set’s most limited way issue, by utilizing execution models. An important issue is the huge information correspondence arranges innovation, transportation and hardware issues. We have broken down four distinctive parallel calculations, which are utilized as a part of the huge information correspondence arrange. This paper demonstrates that, three of the four calculations can be finest in various circumstances, contingent upon exchanges between enormous information on big data computation and communication costs.
