A Core Calculus for Scala Type Checking

Martin Odersky, Vincent Cremet

We present a minimal core calculus that captures interesting constructs of the Scala programming language: nested classes, abstract types, mixin composition, and path dependent types. We show that the problems of type assignment and subtyping in this calcu ...

An Extensible Query Execution Engine for Supporting New Query Execution Models

Query processing in traditional Database Management Systems (DBMS) has been extensively studied in the literature and adopted in industry. Such success is, in part, due to the performance of their Query Execution En-gines (QEE) for supporting the execution ...

An Overview of the Scala Programming Language

Martin Odersky, Michel Schinz, Vincent Cremet, Burak Emir, Stéphane Micheloud, Nikolay Mihaylov, Matthias Zenger, Philippe Altherr

Scala fuses object-oriented and functional programming in a statically typed programming language. It is aimed at the construction of components and component systems. This paper gives an overview of the Scala language for readers who are familar with prog ...

Schema matching for structured document transformations

Aïda Boukottaya

This dissertation studies structured document content reuse problem. In structured document content reuse, a document (or a part of document) structured under one schema must be restructured and translated into an instance of a different schema. Thus, a no ...

Independently Extensible Solutions to the Expression Problem

Martin Odersky, Matthias Zenger

The expression problem is fundamental for the development of extensible software. Many (partial) solutions to this important problem have been proposed in the past. None of these approaches solves the problem of using different, independent extensions jo ...

Iplt-image processing library and toolkit for the electron microscopy community

Henning Paul-Julius Stahlberg, Andreas Engel

We present the foundation for establishing a modular, collaborative, integrated, open-source architecture for image processing of electron microscopy images, named iplt. It is designed around object oriented paradigms and implemented using the programming ...

PiLib: A Hosted Language for Pi-Calculus Style Concurrency

Martin Odersky, Vincent Cremet

PiLib is a library written in Scala that implements the concurrency constructs of the Pi-calculus. Some features of the programming language Scala, examined in the paper, make it possible to use almost the same syntax as in the Pi-calculus. The advantages ...

Monadic Queries over Tree-Structured Data

Christoph Koch

Monadic query languages over trees currently receive considerable interest in the database community, as the problem of selecting nodes from a tree is the most basic and widespread database query problem in the context of XML. Partly a survey of recent wor ...

Implementing Extensible Compilers

Martin Odersky, Matthias Zenger

New extensions to programming languages are constantly being proposed. But implementing these extensions usually turns out to be a very difficult and expensive task, since conventional compilers often lack extensibility and reusability. In this paper we pr ...

Replication of non-deterministic objects

This thesis discusses replication of non-deterministic objects in distributed systems to achieve fault tolerance against crash failures. The objects replicated are the virtual nodes of a distributed application. Replication is viewed as an issue that is to ...
