Large Array of Shape Memory Polymer Actuators for Haptics and Microfluidics

My thesis advances the field of shape memory polymer (SMP) actuators by providing a versatile strategy to arbitrarily reconfigure large arrays of densely packed latching soft actuators. It exploits two key intrinsic characteristics of SMPs, which are their ...

A statistical shape model of the human second cervical vertebra

Simon Nessim Henein, Charles Baur, Marine Chantal Elisabeth Geneviève Clogenson, Reto Meuli

Statistical shape and appearance models play an important role in reducing the segmentation processing time of a vertebra and in improving results for 3D model development. Here, we describe the different steps in generating a statistical shape model (SSM) ...

Quality- and cost-driven assembly technique selection and geometrical tolerance allocation for mechanical structure assembly

Loïc Andolfatto

Abstract The assembly process planning has been the subject of extensive scientific work, mainly due to the multiple aspects involved from geometrical matters to operational research concerns. However, very few issues about assembly technique selection are ...

Solving 112-bit prime ECDLP on game consoles using sloppy reduction

Arjen Lenstra, Joppe Willem Bos, Thorsten Kleinjung, Marcelo Kaihara

We describe a cell processor implementation of Pollard’s rho method to solve discrete logarithms in groups of elliptic curves over prime fields. The implementation was used on a cluster of PlayStation 3 game consoles to set a new record. We present in deta ...

On the Cryptanalysis of Public-Key Cryptography

Joppe Willem Bos

Nowadays, the most popular public-key cryptosystems are based on either the integer factorization or the discrete logarithm problem. The feasibility of solving these mathematical problems in practice is studied and techniques are presented to speed-up the ...

Tactile Feedback Improves Performance in a Palpation Task: Results in a VR-Based Testbed

Hannes Bleuler, Roger Gassert, Evren Samur, Laura Santos Carreras, Kaspar Leuenberger

Robotic surgery provides many benefits such as reduced invasiveness and increased dexterity. This comes at the cost of no direct contact between surgeon and patient This physical separation prevents surgeons from performing direct haptic exploration of tis ...

Efficient SIMD arithmetic modulo a Mersenne number

Arjen Lenstra, Joppe Willem Bos, Thorsten Kleinjung

This paper describes carry-less arithmetic operations modulo an integer 2^M − 1 in the thousand-bit range, targeted at single instruction multiple data platforms and applications where overall throughput is the main performance criterion. Using an implemen ...

Design of a Semi-Implantable Hearing Device for Direct Acoustic Cochlear Stimulation

Yves Perriard, Hans Bernhard

A new hearing therapy based on direct acoustic cochlear stimulation was developed for the treatment of severe to profound mixed hearing loss. The device efficacy was validated in an initial clinical trial with four patients. This semi-implantable investiga ...

Design Methodology and Innovative Device Concept for Acoustic Hearing Implants

Hans Bernhard

Nowadays, hearing impaired people can be treated with a multitude of different devices and surgical interventions that are selected in function of the type and degree of hearing loss of the patient. These known therapies cover the major part of possible he ...
