A recent trend in sustainable bioethanol production is the use of agricultural waste or food as an inexpensive and most available feedstock. Bread major that could be successfully used for bioethanol. The aim this study was to optimize ethanol by response surface methodology (RSM) using bread hydrolysate. Waste hydrolysate obtained crude hydrolytic enzymes produce bacterial isolate Hymenobacter...

Statistical population reconstruction models based on maximum likelihood and minimum chi-square objective functions provide a robust versatile approach to estimating the demographic dynamics of harvested populations wildlife. These employ numerical optimization techniques determine which set model parameters best describes observed age-at-harvest, catch-effort, other auxiliary field data. Altho...

The experience of many programmers shows that it is actually impossible to extract all the faults from a sophisticated software. Therefore it is necessary to estimate the time interval during which the remaining faults will not influence the program. The statistical models which are used to get such estimates are semi-heuristic and lack convincing theoretical explanation. In this paper, we cons...
