This is an abstract of a revision of the original paper (ER'93 pre-proceedings2) that presents a DBMS-independent database reverse engineering (DBRE) methodology based on a generic process model and on transformation techniques. DBRE is proposed as a twophase process consisting in recovering the DBMS-dependent data structures (data structure extraction) then in recovering their semantics (data ...

We recently discovered 5 new putative globally optimum configurations for Morse clusters at ρ = 8. This report contains some algorithmic details as well as the structures determined with our method. Methodology After the success obtained in solving minimum energy conformation problems for Lennard-Jones clusters (see [LS02] and [LS03]) we recently adapted our twophase monotonic basin-hopping str...

In this paper, a source-destination pair, which is augmented by a half-duplex relay, is considered. Two practical partial decode and forward encoding schemes are proposed. In these transmission schemes, the relay may decode the source's signal either partially or completely. In each encoding technique, twophase transmission scheme is developed in which the relay can partially listen to the sour...

A constitutive model is derived from theory of elasticity for predicting ultimate drying shrinkage of concrete. The model was extended by incorporating the semiempirical composite model proposed by Hirsch and Dougill for predicting Young's modulus of concrete. Their composite model is the geometric mean of Paul's upper and lower limit boundaries of a twophase composite. According to the shrinka...

Two-phase flows with dynamic interfaces are ubiquitous in daily life as well as in many industrial applications. Gas bubbles and liquid droplets are typical forms of these twophase flows. In chemical engineering, understanding the dynamics of these bubbles and droplets is crucial to the design and operation of the two-phase flow reactors, ranging from microfluidic devices to large systems such ...

This paper is an extension of the single-phase cohesionless dry granular avalanche model over curved and twisted channels proposed by Pudasaini and Hutter (2003). It is a generalisation of the Savage and Hutter (1989, 1991) equations based on simple channel topography to a twophase fluid-solid mixture of debris material. Important terms emerging from the correct treatment of the kinematic and d...

Rabbit liver plasma membranes were isolated and purified by using an aqueous twophase polymer system. Examination of these preparations with respect to electronmicroscopical appearance, distribution of marker enzymes and gross biochemical composition revealed them to be free from contamination by intracellular components. Sera from ten patients with chronic active hepatitis, four with and six w...

Existing data mining techniques mostly focus on finding global patterns and lack the ability to systematically discover regional patterns. Most relationships in spatial datasets are regional; therefore there is a great need to extract regional knowledge from spatial datasets. This paper proposes a novel framework to discover interesting regions characterized by “strong regional correlation rela...

Aqueous two-phase extraction (ATPE), unique liquid-liquid extraction, involves a transfer of solute from one aqueous phase to another. ATPE includes polymer–polymer type and polymer–salt type systems for the recovery of proteins. The protein must be recovered in a highly purified form in order to improve its quality, decrease energy consumption, reduce waste and minimize costs. To acquire the h...

The knapsack problem (KP) and its multidimensional version (MKP) are basic problems in combinatorial optimization. In this paper we consider their multiobjective extension (MOKP and MOMKP), for which the aim is to obtain or to approximate the set of efficient solutions. In a first step, we classify and describe briefly the existing works, that are essentially based on the use of metaheuristics....
