Practical control methods for vacuum driven soft actuator modules

Jamie Paik, Matthew Aaron Robertson

Vacuum-powered Soft Pneumatic Actuator (VSPA) Modules have been described to afford advantages for rapid development of reconfigurable, multi-DoF soft pneumatic robots powered by vacuum by reducing their logistical complexity, however they also present new ...

Small-animal and endoscopic PET detector modules based on multichannel digital silicon photomultipliers

Edoardo Charbon, Augusto Carimatto, Esteban Venialgo Araujo

In time-of-flight (TOF) positron emission tomography (PET), the coincidence resolving time (CRT) has a strong influence on the overall performance. Multichannel digital silicon photomultipliers (MD-SiPMs) are able to obtain several timestamps for gamma pho ...

MATHICSE Technical Report : Hierarchical B-spline Complexes of Discrete Differential Forms

Rafael Vazquez Hernandez

In this paper, we introduce the hierarchical B-spline complex of discrete differential forms for arbitrary spatial dimension. This complex may be applied to the adaptive isogeometric solution of problems arising in fluid mechanics. We derive a sufficient a ...

Automatic synthesis of rulesets for programmable stochastic self-assembly of rotationally symmetric robotic modules

Alcherio Martinoli, Bahar Haghighat

Programmable stochastic self-assembly of modular robots provides promising means to formation of structures at different scales. One way to address the design of dedicated control rulesets for self-assembling robotic modules is to leverage formalisms based ...

Hail resistance of composite-based glass-free lightweight modules for building integrated photovoltaics applications

Ana Cristina Oliveira Martins

In this work, we manufacture lightweight (5 kg/m2) photovoltaic (PV) mini-modules for building integration replacing conventional glass sheets by a composite sandwich backsheet and a polymeric frontsheet. Our test devices are subjected to hail tests accor ...

The algebra of essential relations on a finite set

Jacques Thévenaz, Serge Bouc

Let X be a finite set and let k be a commutative ring. We consider the k-algebra of the monoid of all relations on X, modulo the ideal generated by the relations factorizing through a set of cardinality strictly smaller than Card(X), called inessential rel ...
