In this short paper I sketch out a problem, which is rarely recognized by designers of programing languages. Null values are a source of many problems and run-time errors as well as some incoherences in language and data model design. I propose a nice and simple solution altering the semantics of variables declarations and give some additional information to the compiler and verifier.

This paper studies the linear fragment of the programing language for quantum computation with classical control described in [4]. We sketch the language, and discuss equivalence of terms. We also describe a fully abstract denotational semantics based on completely positive maps.

This paper presents an enumerative approach for a sports league scheduling problem. This simple method can solve some instances involving a number T of teams up to 70 while the best known constraint programing algorithm is limited to T ≤ 40. The proposed approach relies on interesting properties which are used to constraint the search process.

Neural networks; Neurons; Gene Expression Programing; Chromosomes; Age estimation Abstract This work is about estimating human age automatically through analysis of facial images. It has got a lot of real-world applications. Due to prompt advances in the fields of machine vision, facial image processing, and computer graphics, automatic age estimation via faces in computer is one of the dominan...

Equity measures can be used as working tools to explore management alternatives for :I \ \ater qualit! system. Several example measures of equity are discussed which proved useful in suggesting nra m;inagsment programs, in identifying critical waste dischargers. in suggesting Lones for grouping dischargers. and for understanding given management programs. The example equity measures were evelua...

We derive monogamy relations (tradeoffs) between strengths of violations of Bell's inequalities from the nonsignaling condition. Our result applies to general Bell inequalities with an arbitrary large number of partners, outcomes, and measurement settings. The method is simple, efficient, and does not require linear programing. The results are used to derive optimal fidelity for asymmetric clon...

In nature, annual plants respond to abiotic stresses by activating a specific genetic program leading to early flowering and accelerated senescence. Although, in nature, this phenomenon supports survival under unfavorable environmental conditions, it may have negative agro-economic impacts on crop productivity. Overcoming this genetic programing by cytokinins (CK) has recently been shown in tra...
