In this paper we face the problem of providing a common representation for knowledge learnt from examples and some kind of background knowledge about a given framework. To this end we postulate inheritance hierarchies endowed with some retrieval rules in addition to the inheritance operation. This hierarchies can be algorithmicaly built according to the specifications encoded in our input data....

Inheritance anomaly is a well known problem in concurrent object-oriented programming. Much work has been done in this area recently, but the problem is far from solved. In this paper we propose a simple language construct that solves the inheritance anomaly. Our proposal involves the use of preconditions and post-actions in which synchronization constraints of objects are speciied. Preconditio...

In large process deployments where an enterprise has to model and maintain a large number of processes that are specializations of each other it is advantageous to provide formal support for process specialization called process inheritance. A process inheritance model definition is introduced as well as a process definition language construct for defining process specialization.

The Inheritance Workshop at ECOOP 2002, which took place on Tuesday, 11 June, was the first ECOOP workshop focusing on inheritance after the successful workshops in 1991 [41] and 1992 [48]. The workshop was intended as a forum for designers and implementers of object-oriented languages, and for software developers with an interest in inheritance. It was organized by Andrew P. Black, Erik Ernst,...

Our view of what happens to the Golgi and ER during mitosis in mammalian cells has been shaken once more. Rather than the Golgi contents being recycled through, or mixed with the ER, two recent studies taking complementary approaches, find that the contents of these organelles remain separate throughout mitosis.

This article is an apologia for the design of inheritance in the Grace educational programming language: it explains how the design of Grace’s inheritance draws from inheritance mechanisms in predecessor languages, and defends that design as the best of the available alternatives. For simplicity, Grace objects are generated from object constructors, like those of Emerald, Lua, and Javascript; f...

0001 Biological continuity relies on successful cell division. Research over the years has provided a good understanding of how cells divide to form two daughter cells through mitosis. During mitosis, chromosomes are duplicated and divied up between the cells to provide each daughter cell with a complete copy of the organism’s genome. The cell, however, doesn’t contain only genomic DNA but can ...
