Objectives: Mobile network, ad-hoc network or Wireless ad-hoc network is the latest networking trend today. In the past fifteen years the no. of Mobile phone users has grown exponentially. The perks offered by this wireless mode of networking are open to all: anywhere, anytime, un tethered access to a huge no. of global users. Statistical Analysis: This paper consists of systematic review and analysis of various existing techniques which helps us to cope against such disasters with an actual and sorted representation. In the end, we wind up our results with the merits and demerits of existing methods along with the liabilities of future scope in this area. Findings: The review studies have shown various mobile software vulnerabilities with their advantages, disadvantages along with their future scopes. Application: The application of mobile software networks is innumerable, from mobile browsers to e-commerce to mobile money, there uses are extensive and important.Keywords

Objectives: Utilization and minimization of premature washout of active microbes from the bioreactor and providing better microbe-substrate contact through suitable modification in existing bioreactor models for enhancing biogas production. Methods / Statistical Analysis: A large bioreactor (15000ml) used as control was compared for gas production and pH with two sets3 smaller bioreactors each with capacity 1/3rd of the larger one. One set of three bioreactors were arranged in parallel fashion and the other set was connected in series. This experiment was repeated twice keeping all the considerable aspects same. The gas production patterns obtained were quite similar thus their mean is presented in the results. Findings: Gas production both from the set up in series as well as parallel was found to be 11 to 15% higher in comparison to larger bioreactor used as control. Reactors in series were producing highest biogas during first 7 days but 8th day onwards there was rapid decrement in production due to low pH of the leading tank in the series connection. On the other hand parallel set-up was stable throughout and its gas production pattern was although higher but similar to control. The subdivision method used here for the bioreactor design with arrangement of the sub units in series and parallel has enhanced biogas production, which has made good case for bioreactor optimization in terms of minimizing microbial loss and stabilization of influential parameters like pH, organic loading rate, hydraulic retention time etc. through proper combinations of series-parallel arrangements. Application / Improvements: If series parallel combination is properly chosen as per feed substrate, such a design can properly utilize washed out microbes and undigested organic material in the effluent thus increasing biogas yield.References
