Ada 9X refines the Ada 83 concept of class and introduces class-wide types to support run-time polymorphism. We study how the Ada definition of class compares to other definitions of this term. We examine how run-time polymorphism is introduced in Ada 9X, ...
With Java 5 and C-# 2.0, first-order parametric polymorphism was introduced in mainstream object-oriented programming languages under the name of generics. Although the first- order variant of generics is very useful, it also imposes some restrictions: it ...
Calcium Aluminate Cements (CAC) are renowned in the field of construction for specific applications requiring rapid hardening and chemical resistance. These properties result from rapid exothermic reactions occurring immediately after setting. Due to the m ...
We delegate increasingly sophisticated and complex tasks to computer programs, and we require them to act autonomously on our behalf in distributed environments (eg the web, the grid). Personal Assistants (PA) are computer programs that can be thought as a ...
Pattern matching is a programming language construct considered essential in functional programming. Its purpose is to inspect and decompose data. Instead, object-oriented programming languages do not have a dedicated construct for this purpose. A possible ...
Subtyping tests are essential in typed publish/subscribe infrastructures, especially when the underlying programming language supports subtype conformance, as in Java or C#. These tests are particularly challenging when the publish/subscribe infrastructure ...
One of the fundamental differences between a centralized system and a distributed one is the notion of partial failures. The ability to efficiently and accurately detect failures is a key element underlying reliable distributed computing. In current distri ...
Although useful in the development of distributed systems, current reliable distributed environments, such as group communication toolkits (e.g., ISIS, TOTEM, PHOENIX) or transactional monitors (e.g., ENCINA, TUXEDO), are hardly extensible or customisable ...
This paper presents the algorithms and results of the “idiap” team participation to the ImageCLEFmed annotation task in 2008. On the basis of our successful experience in 2007 we decided to integrate two different local structural and textural descriptors. ...
A traditional multi-layered approach is adopted to human body modeling and deformation. The model is split into three general anatomical structures: the skeleton, musculature and skin. It is shown that each of these layers is modeled and deformed by using ...
