A functional programming language can be taught successfully as a first language, but if there is no follow up the students do not appreciate the functional approach. Following discussions concerning this issue at the 1995 FPLE conference [1] we decided to develop such a follow up by writing a book that teaches C to students who can write simple functional programs. This paper summarises the es...

The ground, oneand two-particle states of the (1+1)-dimensional massive sine-Gordon field theory are investigated within the framework of the Gaussian wave-functional approach. We demonstrate that for a certain region of the model-parameter space, the vacuum of the field system is asymmetrical. Furthermore, it is shown that two-particle bound state can exist upon the asymmetric vacuum for a par...

As an alternative to the price-based traditional auction model, the multi-attribute auction model is an integrated model requiring the simultaneous trade of different types of attributes as the sellers and buyers deal. As a result, the design and modeling of the auction mechanism have become very difficult. This paper proposes a multiattribute auction model using the dominance-based rough sets ...

Given that ODMG 3.0 specifications do not address the definition of external schemas, we are developing an external schema definition methodology for ODMG databases. In this paper, an extension of ODMG metadata is proposed to support the definition of external schemas. In particular, metadata for derived classes and derived interfaces are defined, as well as some modifications to define inherit...

An approach to software development problems is presented, and illustrated by an example. The approach is based on the ideas of problem frames and structuring speci cations by views. It is claimed that decompositions obtained by this approach result in a more e ective separation of concerns, and that the resulting components are more likely to be reusable than those obtained by more conventiona...

In this paper we present a functional approach to capture the information conveyed by various time expressions within a discourse. The approach is motivated by annotation scheme that captures general temporal relations between events expressed in a discourse. A parser for Czech as well as an inference engine that makes it possible to compare functional compositions is implemented.

In this paper, an entropy based associative memory model will be proposed and applied to memory retrievals with an orthogonal learning model to compare with the conventional model based on the quadratic Lyapunov functional to be minimized during the retrieval process. In the present approach, the updating dynamics will be constructed on the basis of the entropy minimization strategy which may b...

The fast development and increasing use of 3D video technology increases the need for standardization and certification processes when it comes to quality of video experience. Due to the specific conditions necessary for high-quality 3D video reproduction, an important role in evaluating the quality of 3D video plays the human experience factor. In order to find the best mechanisms for 3D video...

Certain classes of problems amenable to description using Problem Frames, in particular ones intended to be implemented using a distributed architecture, can benefit by the addition of a cardinality specification on the domain interfaces. This paper presents an example of such a problem, demonstrates the need for relationship cardinality, and proposes a notation to represent cardinality on doma...
