The application of response surface methodology (RSM) and central composite rotatable design (CCRD) is beneficial in optimization of variables. The use of these methods, for the influence of some operating variables on the performance of a stripper for groundnut pod is discussed in this paper. Three stripper operating variables, drum speed, loop tip height and loop spacing were changed during the stripping tests based on CCRD. The ranges of variables used in the stripper design were drum speed (666 to 999 m min-1), loop tip height (52 to 68 mm), and the loop spacing (88 to 108 mm). A total of 20 pod stripping tests were conducted using stripper on groundnut crop. In order to optimize the mass of pod stripped, mathematical models were developed using computer simulation by least squares method and a Design-Expert, software. Models were developed for stripping capacity (SC) and the stripping efficiency (SE) and pressed as a function of the three operating variables. The results of the study indicate that the SC was significantly affected by all the three parameters (p<0.0001) at the linear and quadratic levels but no significant effect was observed at the interactions level; while SE was significantly influenced by the loop tip height and drum speed (p<0.0001) at the linear level.

Software Cost Estimation with resonating dependability, gainfulness and advancement exertion is a testing and cumbersome undertaking. This has actuated the product group to give much required push and dig into broad research in programming exertion estimation for developing complex strategies. Estimation by similarity is one of the convenient methods in programming exertion estimation field. Notwithstanding, the strategy used for the estimation of programming exertion by similarity is not ready to handle the straight out information in an express and exact way. Another approach has been produced in this paper to gauge programming exertion for ventures spoke to by absolute or numerical information utilizing thinking by similarity and fluffy methodology. The current chronicled datasets; broke down with fluffy rationale, produce exact brings about correlation to the dataset investigated with the prior systems. © 2014 SERSC.
