In the present work the drying characteristics and proximate analysis of turkey berry (Solanum torvum) were analyzed under open sun drying and greenhouse drying with two different glazing materials (UV Polyethylene sheet and Drip lock sheet) under passive and active modes. The drying rate under different modes of drying are 18.73g/h in drip lock greenhouse active mode,12.50 g/h in UV polyethylene sheet greenhouse active mode,15.22 g/hin drip lock sheet greenhouse passive mode, 11.84 g/h in UV polyethylene sheet greenhouse passive mode and 10.65 g/h in open sun drying. Twelve mathematical models were chosen to determine the drying characteristics of Turkey berry. From the statistical analysis it is found that Modified Henderson and Pabis model is the best drying model describing thin layer drying characteristics of turkey berry in both open sun drying and green house drying. The goodness of the fit achieved is based on the values of coefficient of determination(R2), sum square error(SSE), root mean square error(RMSE) and reduced chi square (?2).From the proximate analysis of dried turkey berry it is found that more amount of carbohydrate is retained in UV polyethylene greenhouse dryer under passive mode. In drip lock greenhouse dryer under passive mode the retention of vitamins such as protein, vitamin C and ash content showed a positive sign. In drip lock greenhouse dryer under active mode the retention of calcium, iron and dietary fibre is found to be high. Finally it is observed that more amounts of nutrients are retained in greenhouse drying than in open sun drying.

This paper presents an experimental investigation for deflection control of two degree of freedom building-like structure system against scaled Northridge Earthquake by using PI (Proportional-Integral) controlled active mass damping. Proposed structure consist of two floors with a cart mounted on the second floor such as active mass damping (AMD) and which is used to suppress horizontal deflections. Moreover a shake table under the structure is used to create the acceleration effect of scaled earthquake. Kp and Ki gain parameters of PI controller is determined by observing passive mode behaviour of the structure against Northridge and it is used to control cart movement according to pre-determined deflection criterias of the floors. Deflection and acceleration results of the floors are obtained separately for passive and active mode responses of the system in the form of graphics.
