Recursive Procedures in Sire Evaluation

Covariances among sire by breed group of dam interaction effects in multibreed sire evaluation procedures.

In multibreed populations, bulls need to be evaluated for additive and nonadditive genetic effects. When the nonadditive genetic effects associated with a bull are defined as sire x breed-group-of-dam interactions, they can be expressed as linear combinations of interactions between alleles of one or more breeds at one or more loci. If these specific allelic interactions are assumed to be indep...

Environmental correlations in sire evaluation.

Correlations were computed among averages of first lactation deviations from herdmate averages of groups of artificially sired daughters of the same Holstein bulls. The groups were constructed by specifying the time interval between animals in the different groups. Comparison of the actual correlations with the expected correlations suggests that environmental correlations are small or nil amon...

An Analysis of Parameter Evaluation of Recursive Procedures

A class of recursive program schemata PR is defined abstracting ALGOL-like procedures. Four generic types of parameter evaluation are considered; call by value, PRV, call by copy, PRc, call by reference, PRr, and call by name, PRj. Two other types of theoretical interest are also considered: "normal evaluation", Ffin, a non-side effect, evaluation postponement mechansim and call by ouote, PRq, ...

PRP - Parallel Recursive Procedures

It is believed that writing parallel programs is hard. Therefore a paradigm for writing parallel programs that is not much harder than writing a sequential program is in demand. This paper describes a general method for parallelizing programs based on the idea of using recursive procedures as the grain of parallelism (PRP). This paradigm only adds a few new constructs to an ordinary sequential ...
