Development of a Fuzzy Logic Model for Predicting Faecal Coliforms in a Freshwater Lake[ ]


Faecal contamination plays a major role in the transmission of diarrhoeal diseases. Thus it is highly desirable to model the water quality in terms of faecal contamination. In this study, an inductive model using fuzzy logic is developed to predict the faecal coliform concentration by taking Sasthamkotta lake as the case study which a freshwater wetland and a Ramsar site in the Southern part of India. Five input water quality parameters namely pH, temperature, dissolved oxygen, biochemical oxygen demand and turbidity during the period 2013 and 2017 was used to develop the said model. A statistical regression model was also developed using the same input parameters.

Evaluating the Impact of Sand and HBS&W on Crude Oil Production at Egbema Field of Niger Delta[ ]


Sand and HBS&W (High basic sediments and water) production is a serious problem in many oil and gas assets worldwide. Both can drastically affect production rates; damage downhole, subsea, and surface facilities, increase the risk of catastrophic failures; and cost operators tens of billions of dollars annually. Water handling costs are high and sand management is complicated that cannot be addressed by a one-size-fits-all approach.

AIR QUALITY ASSESSMENT OF SOME SELECTED UNCONTROLLED DUMPSITE IN WARRI METROPOLITAN CITY[ ]


The air quialty of six selected uncontrolled dumpsite monitored revealed the impact of municipal solid waste on the air quality of Warri municipal area. The study covers three months (August – October 2019) at Opete, Okuvo, NPA, Cemetery Road, Refinery Road and Osubi. The Aeroqual 500 series was used to investigate the parameters such as SPM, H2S, NOx, CO, SOx, O3 and CxHy/VOCs. The comparison of the emitted gases results in the following order, SPM > NOx > SOx > H2S > O3 > CxHy/VOCs > CO. Moreover, Opete has the highest average emissions of most gasses such as CO, H2S, NOx, and O3 (31.42%, 43.81%, 18.86% and 17.66%), while SPM and SOx were the major emissions from Okuvo dumpsite.

Physical Design Implementation LDO[ ]


This project aims to implement a LDO on physical design flow from netlist to GDSII that starts from floorplan, placement, CTS, routing and ends with physical verification checks such as DRC, LVS and ERC, antenna design rule. Floorplanning is the basic building step for any hierarchical physical design flow. Floorplanning is taking more amount of time in entire design hierarchical flow. If floorplanning is not good the entire design will take more time and it will increase a greater number of iterations to complete the design. In this paper we have demonstrated different physical design techniques to optimize the area and fit the same design on optimized die size without compromising on the design features.

A Review on Computational Complexity Theory and Classes of Problems[ ]


There are various classes of problems in complexity theory also some mathematical precisely defined problems that cannot be solved by algorithms even for unlimited time. Yuri Matiyasevich and Alan Turing proved that no such algorithms exist to solve the halting problems. Turing machines also called computing machines are not algorithms but they provide mathematical definition of objects so that one can prove their existence or none-existence.

Dynamics of 125 mm High Explosive Projectile for Main Battle Tank[ ]


In the battle field tank ammunition was mostly used to create punching hole in the armour of other tanks in the very early days. With the changing technology, tank has become a mobile gun platform to provide infantry the close fire sp. Now a days the main battle tanks are using high explosive projectiles for all round purpose. Success of those projectiles largely de-pends on the range and accuracy of it. Again, there are some impact factors like drag & lift for which the trajectory of those projectiles will be affected and in turn, it will affect its range & accuracy.

Heat transfer coefficient and skin friction determination of thermal radiation effects on MHD convective flow of alumina nanofluid through a non-Darcian porous plate[ ]


This work, analyzes the effect of thermal radiation on MHD alumina nanofluid through a non-Darcian porous medium. A Homotopy Pertubation Method (HPM) is employed to determine the temperature and velocity profiles of the nanofluid in order to consider the skin friction, heat transfer coefficient and other parameters that influenced the fluid. Using numerical computations, it is observed that increase in the Prandtl number (Pr), heat source term (Q > 0), magnetic Hartmann number (Ha), Porosity term and Grashof number (Gr) showed a decrease in the skin friction at the wall of the plate while increase in Reynolds number (Re), heat sink term (Q < 0) and radiation term (N) result in an increase in the skin friction.

Differentiating objective and subjective semantics using Text mining and Web Scraping: A Comparative Study[ ]


The active and rapid production of a large amount of digital data and the need to rearrange it into a readable and usable format is not feasible manually. However, using Web Scraping and Automation, a considerable amount of data can be collected, and the analysis of that data can draw reasonable outcomes. After extracting the desired text from the data source, the quantity of output almost makes it impossible to be interpreted without computational support. To conclude a useful result from the data, it has to be statistically identified and later classified based on the main sentiments expressed in that text.

Environment Impact Assessment of Thermal Power Plant for Sustainable Development[ ]


Thermal Power plants are the major source of generation of electricity for any developing country. Around 61.8% of electricity generation in our country is met by thermal power plants. Fuel is blown into the combustible chamber of the boiler where it is burnt at high temperature where Heat energy converts water into steam. High energy steam is passed through the turbine and the steam creates force on the turbine causing the shaft to rotate at high speed. A generator is coupled at one end of the turbine shaft which generates power. The thermal power plant has serious impacts on land, soil, air and various social impacts.
