A minimally tuned composite Higgs model from an extra dimension

Duccio Pappadopulo, Riccardo Torre, Andrea Thamm

We construct and study the 5D realization of a composite Higgs model with minimal tuning. The Higgs is a (pseudo-)Goldstone boson from the spontaneous breaking of a global SO(5) symmetry to an SO(4) subgroup. The peculiarity of our construction lies in the ...

Robust Data-Driven Dynamic Programming

Daniel Kuhn, Grani Adiwena Hanasusanto

In stochastic optimal control the distribution of the exogenous noise is typically unknown and must be inferred from limited data before dynamic programming (DP)-based solution schemes can be applied. If the conditional expectations in the DP recursions ar ...

Enhanced safety with post-installed shear reinforcement

Aurelio Muttoni, Miguel Fernández Ruiz

The safety of existing concrete slabs against shear may be insufficient for several reasons such as design and construction errors, structural modifications or increased loads. Moreover, the knowledge about shear design has significantly increased over the ...

Transition Slabs of Integral Abutment Bridges

Aurelio Muttoni, Olivier Burdet, Damien Dreier

Over the past decades, an increasing number of bridges with integral abutment have been built in Switzerland. This type of bridge offers various advantages over standard bridges with abutments, equipped with expansion joints and bearings that require regul ...

Quasi-static cyclic tests of two prefabricated, reinforced masonry walls

Katrin Beyer, Michael Markus Rupf, Alessandro Dazio

In the second half of the 20th century, the majority of residential buildings in Switzerland have been built with unreinforced brick masonry walls and reinforced concrete floors. Following a re-evaluation of the seismic hazard in Switzerland, a country of ...

Bayesian variable order Markov models

Christos Dimitrakakis

We present a simple, effective generalisation of variable order Markov models to full online Bayesian estimation. The mechanism used is close to that employed in context tree weighting. The main contribution is the addition of a prior, conditioned on conte ...

Sensorless Position Detection of a Linear Actuator

Nikola Katic

The goal of the project is to explore the possibility of controlling the speed of the actuator’s moving part without using any sensor. The speed has to be set accordingly to the position of the moving part at specific time. This dependency is fixed and is ...

Optimization of cascade stilling basins using GA and PSO approaches

David Andrew Barry, Roham Bakhtyar

In high head dams, the kinetic energy at the spillway toe is very high and the tail-water depth available for energy dissipation is relatively small. Cascade stilling basins are energy dissipation systems for high head dams, the design of which is based on ...

Evaluation of bamboo for building elements satisfying housing criteria

David Javier Guzman Chavez

Bamboo – identified as a Non Timber Forest Product (NTFP) – offering optimal mechanical properties for construction purposes, and at the same time little studied among contemporary building materials, is paradoxically most used in precarious housing. The u ...

Dynamic programming approach to optimal design of cascade stilling basins

Roham Bakhtyar

Energy dissipation systems such as single fall-stilling basin and single chute bucket have been used in the design and construction of large dams. In the case of high head structures, however, due to the high flow velocity, these systems suffer from proble ...
