The concept of Precision Dairy Farming is, to a crucial degree, based on data collection related to individual animals. In dairy farming, the amount of data per individual animal will increase. Thus, a particular meaning has the use of this data through decision support systems. A particular meaning has the use of this data through decision support system In the present article, the chosen exam...

We introduce a mean-field extension of the LIBOR market model (LMM) which preserves basic features original model. Among others, these are martingale property, directly implementable calibration and an economically reasonable parametrization classical LMM. At same time, (MF-LMM) is designed to reduce probability exploding scenarios, arising in particular market-consistent valuation long-term gu...

A famous travelling salesman problem, appearing simple to state but complex solve, has been widely investigated and various algorithms have proposed. In this article, mixed integer linear programming of python (MIP) is used model problem with varying input data. The result shows that small data the modelling code MIP executing quickly converging optimal value, while large scale require plenty c...

The authors are to be congratulated for an interesting paper which highlights the need for more formal procedures on the assessment of goodness of fit in the area of mixed models. The authors give a comprehensive overview of diagnostic techniques and goodness-of-fit tests for random effects in mixed models and propose a number of new nonparametric tests with omnibus character. Some of them are ...

It is shown that a method of robust estimation in a two way crossed classification mixed model, recently proposed by Bednarski and Zontek (1996), can be extended to a more general case of variance components model with commutative a covariance matrices.

pedigree information of 3972 holstein cows and bulls, from 1961 to 2008, was used to calculate inbreeding coefficients and their effects on production traits and subclinical mastitis of dairy farm cows inazerbaijan province,iran. inbreeding was included in a linear mixed model as a class variable. data were analyzed using the proc mixed of sas by mivque method. results showed that average inbre...

this paper deals with scrutinizing the convergence properties of iterative methods to solve linear system of equations. recently, several types of the preconditioners have been applied for ameliorating the rate of convergence of the accelerated overrelaxation (aor) method. in this paper, we study the applicability of a general class of the preconditioned iterative methods under certain conditio...

copper amine oxidases are important enzymes, which contribute to the regulation of mono- and polyamine levels. each monomer contains one cu(ii) ion and 2,4,5-trihydroxyphenylalanine (tpq) as cofactors. they catalyze the oxidative deamination of primary amines to aldehydes with a ping-pong mechanism consisting of a transamination. the mechanism is followed by the transfer of two electrons to mol...
