Optimization of multi-group energy structures for diffusion analyses of sodium-cooled fast reactors assisted by simulated annealing - Part I: Methodology demonstration

Konstantin Mikityuk, Vincenzo Anthony Di Nora

This study presents an approach to the selection of optimal energy group structures for multi-group nodal diffusion analyses of Sodium-cooled Fast Reactor cores. The goal is to speed up calculations, particularly in transient calculations, while maintainin ...

A Computational Method for Identifying the Optimum Buffer Size in the Era of Zero Defect Manufacturing

Dimitrios Kyritsis, Ali Boujemaoui, Foivos Psarommatis Giannakopoulos

Decreasing defects, waste time, meeting customer demand and being adaptable are the goals of a Zero Defect Manufacturing (ZDM) strategy. Scheduling is an important tool to perform that. It should take in account buffer size allocation. In this study, a met ...

Heterogeneous Target Assignment to Robotic Fiber Positioner Systems

Denis Gillet, Jean-Paul Richard Kneib, Matin Macktoobian

The target assignment methods applied to robotic fiber positioners are only applicable to homogeneous sets of targets to be observed. However, different batches of robotic fiber positioners available at the focal plane of a telescope can be simultaneously ...

Accuracy Assessment of Nonlinear Seismic Displacement Demand Predicted by Simplified Methods for the Plateau Range of Design Response Spectra

Pierino Lestuzzi, Lorenzo Diana

The non-linear seismic displacement demand prediction for low-period structures, i.e. with an initial fundamental period situated in the plateau of design response spectra is studied. In Eurocode 8, the computation of seismic displacement demands is essent ...

Optimized Packet Scheduling in Multiview Video Navigation Systems

Pascal Frossard, Thomas Maugey, Laura Toni

In multiview video systems, multiple cameras generally acquire the same scene from different perspectives, such that users have the possibility to select their preferred viewpoint. This results in large amounts of highly redundant data, which needs to be p ...

Evolution of division of labor in artificial societies

Pawel Lichocki

Natural and artificial societies often divide the workload between specialized members. For example, an ant worker may preferentially perform one of many tasks such as brood rearing, foraging and nest maintenance. A robot from a rescue team may specialize ...

Very High Speed Slotless Permanent Magnet Motors: Analytical Modeling, Optimization, Design and Torque Measurement Methods

Yves Perriard, Pierre-Daniel Pfister

This paper presents a very-high-speed (VHS) slotless permanent-magnet motor design procedure using an analytical model. The model is used to design the optimal prototype (target: 200 kr/min, 2 kW). The multiphysics analytical model allows a quick optimizat ...

Design of tensegrity structures using parametric analysis and stochastic search

Ian Smith, Landolf-Giosef-Anastasios Rhode-Barbarigos, Himanshu Jain

Tensegrity structures are lightweight structures composed of cables in tension and struts in compression. Since tensegrity systems exhibit geometrically nonlinear behavior, finding optimal structural designs is difficult. This paper focuses on the use of s ...
