This paper develops a simple calculus for order of magnitude reasoning. A semantics is given with soundness and completeness results. Order of magnitude probability functions are easily defined and turn out to be equivalent to kappa functions, which are slight generalisations of Spohn’s Natural Conditional Functions. The calculus also gives rise to an order of magnitude decision theory, which c...

We present a method for hierarchically generating sound workflow nets by substitution of nets with multiple inputs and outputs. We show that this method is correct and generalizes the class of nets generated by other hierarchical approaches. The method involves a new notion of soundness which is preserved by the generalized type of substitution that is with the presented type of generalized sub...

In this paper a general procedure is proposed for experimental evaluation of Cartesian Stiffness matrix. The proposed procedure is based on a trilateration technique that is applied for a new tracking system named as Milli-CaTraSys (Milli Cassino Tracking System). A case of study for experimental evaluation of the stiffness matrix is presented in order to show the soundness of the proposed proc...

Analysing DNA that organisms release into the environment (environmental DNA, or eDNA) has enormous potential for assessing rare and cryptic species. At present the method is only reliably used to assess the presence-absence of species in natural environments, as seasonal influences on eDNA in relation to presence, abundance, life stages and seasonal behaviours are poorly understood. A naturall...

This paper presents an overview of the history and the foreseeable developments of animal breeding. After the transition from population genetics to modern quantitative genetics, realized in the late 1950s, major progress has occurred in the field of breeding value evaluation and, more recently, with the advent of genomics and its potential contribution to genetic improvement. Various challenge...

We present an evaluation technique for proving strong normalization (SN). We use the technique to give SN proofs for F 2 , F-bounded quantiication, subtypes, and F !. The evaluation technique derives SN as a corollary of the soundness of the typing rules under an appropriate evaluation semantics. The evaluation semantics yields simpler type sets than those used in the earlier SN proofs. The typ...

Relationships between breeding field-test traits and competition traits were studied to investigate whether the latter could be usefully included in the genetic evaluation of Icelandic horses. The current method of genetic evaluation is based on records from breeding field-tests only. The breeding field-test data included 16401 individual records of Icelandic horses evaluated in 11 countries du...

The region calculus of Tofte and Talpin is a polymorphically typed lambda calculus with annotations that make memory allocation and deallocation explicit. It is intended as an intermediate language for implementing Hindley-Milner typed functional languages such as ML without traditional trace-based garbage collection. Static region and effect inference can be used to annotate a statically typed...
