Assessing the microstructure of motion correspondences with non-retinotopic feature attribution

Michael Herzog, Thomas Otto

The motion correspondence problem, one of the classical examples of perceptual organization, addresses the question of how elements are grouped across space and time. Here, we investigate motion correspondences using a new feature attribution technique. We ...

Failure detectors as type boosters

Rachid Guerraoui

The power of an object type T can be measured as the maximum number n of processes that can solve consensus using only objects of T and registers. This number, denoted cons(T), is called the consensus power of T. This paper addresses the question of the we ...

A Conceptual View on Trajectories

Stefano Spaccapietra, Christine Parent, Christelle Vangenot, Maria Luisa Damiani, José Antonio Fernandes de Macedo

Analysis of trajectory data is the key to a growing number of applications aiming at global understanding and management of complex phenomena that involve moving objects (e.g. worldwide courier distribution, city traffic management, bird migration monitori ...

To Share or Not To Share?

Anastasia Ailamaki, Babak Falsafi, Frederick Ryan Johnson, Ippokratis Pandis

Intuitively, aggressive work sharing among concurrent queries in a database system should always improve performance by eliminating redundant computation or data accesses. We show that, contrary to common intuition, this is not always the case in practice, ...

Implementation of a Modeling Tool Using Alloy as Meta-Modeling Language and CrocoPat as Validation Tool

Alain Wegmann, Lam Son Lê, Dirk Thilo Beyer, Lotfi Hussami

The context of our work is a project that focuses on methods and tools for modeling enterprise architectures. An enterprise architecture model represents the structure of an enterprise across multiple levels, from the markets in which it operates down to t ...

Distributed Subtyping

Rachid Guerraoui, João Barreto

One of the most frequent operations in object-oriented programs is the "instanceof" test, also called the "subtyping" test or the "type inclusion" test. This test determines if a given object is an instance of some type. Surprisingly, despite a lot of rese ...

Semantic Overlay Networks

Karl Aberer, Philippe Cudré-Mauroux

In a handful of years only, Peer-to-Peer (P2P) systems have become an integral part of the Internet. After a few key successes related to music-sharing (e.g., Napster or Gnutella), they rapidly developed and are nowadays firmly established in various conte ...

Better Relational Queries using For-comprehensions

Gilles Dubochet

For-comprehensions, an operator to apply expressions on selected elements of sets or lists, can replace most of SQL as a query language. I present my current and future work on integrating for-comprehensions for database access in general-purpose programmi ...
