Feature selection is problematic when the number of potential features is very large. Absent distribution knowledge, to select a best feature set of a certain size requires that all feature sets of that size be examined. This paper considers the question in the context of variable selection for prediction based on the coe!cient of determination (CoD). The CoD varies between 0 and 1, and measure...

To meet the increasing demand for value-added fresh cod loins in the EU retail market, it is important to develop new technologies and preservation methods to effectively extend the shelf-life and improve the eating quality of fresh cod loins. The aim of this study was to investigate the effects of combined application of MAP and superchilled storage on the shelf-life extension of fresh cod loi...

Pilot plant study showed that there is a relationship between the HRT in aeration tank and the % removal of soluble COD in the final settler if DO is not a limiting function. It was found that the % removal of soluble COD in final settler increased from 13 at HRT in aeration tank of 12 hours to 45 at HRT of 4 hours. Mathematical model was also presented in order to predict the soluble COD utili...

Brewing is the process is for production of beer [1,2]. It is said that for every 1 liter of beer production approximate 10 liters of water is used [3]. The water in any brewery is typically used for brewing, rising and cooling process [3]. The various steps that are involved in brewing process are malt production and handling, worth preparation, fermentation, filtration, CIP and finally packag...

The reaction of gem-dithiol compounds R 2C(SH) 2 (R = Bn (benzyl), (i) Pr; R 2 = -(CH 2) 4-) with dinuclear rhodium or iridium complexes containing basic ligands such as [M(mu-OH)(cod)] 2 and [M(mu-OMe)(cod)] 2, or the mononuclear [M(acac)(cod)] (M = Rh, Ir, cod = 1,5-cyclooctadiene) in the presence of a external base, afforded the dinuclear complexes [M 2(mu-S 2CR 2)(cod) 2] ( 1- 4). The monod...

BACKGROUND Cod liver oil is an important source of vitamin D, but also contains other fat-soluble components such as vitamin A. Before 1999, the cod liver oil formula in Norway contained a high concentration of vitamin A (1000 µg per 5 ml). High vitamin A status is associated with increased risks of several chronic diseases. OBJECTIVE To investigate the association between cod liver oil intak...

Grey model (GM) and artificial neural network (ANN) was employed to predict suspended solids (SS) and chemical oxygen demand (COD) n the effluent from sequence batch reactors of a hospital wastewater treatment plant (HWWTP). The results indicated that the minimum mean bsolute percentage errors (MAPEs) of 23.14% and 51.73% for SS and COD could be achieved using genetic algorithm ANN (GAANN). The...
