Design of a compliant load cell with adjustable stiffness

Charles Baur, Lennart Rubbert, Michal Stanislaw Smreczak

Manipulation at the sub-micron scale often requires force-sensing capabilities of milli-to nanonewton forces. This article presents a novel design of a compliant load cell with mechanically adjustable stiffness. The system enables adapting force sensitivit ...

A Comparison between Two Automatic Assessment Approaches for Programming: An Empirical Study on MOOCs

Pierre Dillenbourg, Patrick Jermann

Computer-graders have been in regular use in the context of MOOCs (Massive Open Online Courses). The automatic grading of programs presents an opportunity to assess and provide tailored feedback to large classes, while featuring at the same time a number o ...

Energetic Macroscopic Representation (EMR) and control scheme for the asymmetric 4-stage MSBA

Alfred Rufer, Gina Kristin Steinke

The Multistage Stacked Boost Architecture (MSBA) is a non-isolated step-up converter topology intended for renewable energy generation systems or distribution networks. In previous papers the functionality and intended applications for this topology have b ...

Search Techniques for Code Generation

Tihomir Gvero

This dissertation explores techniques that synthesize and generate program fragments and test inputs. The main goal of these techniques is to improve and support automation in program synthesis and test input generation. This is important because performin ...

Optimized distributed implementation of multiparty interactions with Restriction

Joseph Sifakis

Using high level coordination primitives allows enhanced expressiveness of component-based frameworks to cope with the inherent complexity of present-day systems designs. Nonetheless, their distributed implementation raises multiple issues, regarding both ...

Improving Scalability of Symbolic Execution for Software with Complex Environment Interfaces

Stefan Bucur

Manual software testing is laborious and prone to human error. Yet, among practitioners, it is the most popular method for quality assurance. Automating the test case generation promises better effectiveness, especially for exposing corner-case bugs. Symbo ...

Application of the Cradle to Cradle paradigm to a housing unit in Switzerland: Findings from a prototype design

Marilyne Andersen, Shady Galal Mohamed Attia, Jean François Bernard Beney

The Cradle to Cradle (C2C) paradigm is emerging as an important regenerative design approach. C2C is aiming to create a positive footprint of the built environment, beyond carbon neutrality. However, there are very few studies that address the application ...

Designing Augmented Reality for the Classroom

Sébastien Cuendet, Pierre Dillenbourg, Quentin Bonnard

Augmented reality (AR) has recently received a lot of attention in education. Multiple AR systems for learning have been developed and tested through empirical studies often conducted in lab settings. While lab studies can be insightful, they leave out the ...

Finding Almost-Invariants in Distributed Systems

Dejan Kostic, Maysam Yabandeh, Marco Canini

It is notoriously hard to develop dependable distributed systems. This is partly due to the difficulties in foreseeing various corner cases and failure scenarios while implementing a system that will be deployed over an asynchronous network. In contrast, r ...

Reflexes: programming abstractions for highly responsive computing in Java

Jesper Honig Spring

Achieving sub-millisecond response times in a managed language environment such as Java introduces significant implementation challenges. The Achilles' heel of Java is its reliance on automatic memory management for reclaiming dead objects. Typically, the ...

Design of multimodal dialogue-based systems

Miroslav Melichar

Multimodal dialogue systems integrate advanced (often spoken) language technologies within human-computer interaction methods. Such complex systems cannot be designed without extensive human expertise and systematic design guidelines taking into account th ...

Distributed Consensus, Revisited

Rachele Fuzzati, Massimo Merro

We provide a novel model to formalize a well-known algorithm, by Chandra and Toueg, that solves Consensus among asynchronous distributed processes in the presence of a particular class of failure detectors (Diamond S or, equivalently, Omega), under the hyp ...

Concrete syntax definition for modeling languages

Frédéric Fondement

Model Driven Engineering (MDE) promotes the use of models as primary artefacts of a software development process, as an attempt to handle complexity through abstraction, e.g. to cope with the evolution of execution platforms. MDE follows a stepwise approac ...
