The study focused on the fundamental analysis of different company with the same sector or industry. The prime objective of this study are to find out the best future perspective and expected good future growth compare to other with the based on historical performance. Selected two banking company which is listed in Indian stock exchange and over the ten year financial data. Considered four indicator of barometer of the companies are: earning per share, dividend per share, return on equity and return on assets. Used mean difference of each variable for the purpose of testing the significant of the variable of this study. On the basis of the financial data and limited period of the study might be concluding that private bank focused good signal then public bank. But in our study conducted very small sample only two bank, in case of large sample it’s may be opposite result.

The study was carried out to evaluate the seasonal variation of some physicochemical parameters of various Khal in Chitagong during the 2018, the water samples were collected three times winter, summer and rainy season respectively. The result revealed that the value of pH, EC, salinity, total hardness, turbidity, TSS, TDS and alkalinity were higher in winter season compared to other seasons. Almost of all sites the content of EC, salinity, TSS, TDS, Chloride and turbidity crossed the limit of ECR(1997), US EPA (2018) and BIS 10500 (2012) but turbidity is more significant in Bridgeghat Khal (5690 NTU) during dry season which is about 569 times higher than the limit of ECR(1997), US EPA (2018) and BIS 10500 (2012). It is because the dilutions of contaminants were drastically reduced in the dry season due to lack of sufficient stream flow. TDS content exceeded the limit of ECR(1997), US EPA (2018) and BIS 10500 (2012) in Canal No. 15 and 7 (Mohesh Khal and Bridgeghat Khal) during winter season which may be due to mixing of industrial waste and dumping of different domestic from the surrounding city dwellers. In all seasons TSS value exceeded the limit of ECR (1997), US EPA (2018) and BIS 10500 (2012) in most of the places which may be due to continuous discharges of combined industrial, domestic and municipal wastes from nearby industries and localities with no stream flow.

The transmission system has poor reliability and more power fluctuations due to insufficient reactive power support into the network. Distributed Static Compensator (DSTATCOM) is highly efficient component for this issue which improves power quality and dynamic performance of the system. The main power quality issue is voltage sag because of which there are considerably much economic and component losses. This paper presents fuzzy logic-based controller which mitigates voltage sag and total harmonic distortion (THD) into the system. This programmable fuzzy logic controller can be used both into linear and non-linear loads efficiently. The performance of the fuzzy logic controller used with the DSTATCOM is been analyzed at the transmission side by using 3-F. The issues resolved are been studied are done and control strategies are been tested by using MATLAB/Simulink.
