Estimating pollution spread in water networks as a Schrödinger bridge problem with partial information

Isabel Haasler

Incidents where water networks are contaminated with microorganisms or pollutants can result in a large number of infected or ill persons, and it is therefore important to quickly detect, localize and estimate the spread and source of the contamination. In ...

Chasing Leaks in a Water Distribution Network by Solving Prize-Collecting Steiner Arborescence Problems

Thomas Liebling

We consider the problem of optimizing a novel acoustic leakage detection system for an urban water distribution network composed of a number of detectors and transponders to be placed in a choice of hydrants such as to provide a desired covering under give ...

On improving the efficiency of modifier adaptation via directional information

Dominique Bonvin

In real-time optimization, the solution quality depends on the model ability to predict the plant KarushKuhn-Tucker (KKT) conditions. In the case of non-parametric plant-model mismatch, one can add input-affine modifiers to the model cost and constraints a ...

A new wake model and comparison of eight algorithms for layout optimization of wind farms in complex terrain

Fernando Porté Agel

Layout optimization of wind farms constitutes an important and challenging task in complex terrain. This is especially due to the complex interactions of the boundary layer flows in complex terrain and wind turbine wakes, which renders wake modelling in co ...

Robust Software Development for University-Built Satellites

Simon Bliudze, Anton Ivanov

Satellites and other complex systems now become more and more software dependent. Even nano satellites have complexity that can be compared to scientific instruments launched to Mars. COTS components and subsystems may now be purchased to support payload d ...

Optimal location of micro-turbines in water supply network

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Irene Almeida Samora

Micro-hydropower is currently expanding as a solution to improve the efficiency of water systems by using energy excesses which are typically lost. In the particular case of water supply systems, often excessive pressure exists in zones of the network conn ...

Combining Statistical Evidence

Stephan Morgenthaler, Robert Staudte

The combination of evidence from independent studies has a curious history. The origins reach back at least to the beginning of the 20th century. Since the mid-1970s, meta-analysis has become popular in several fields, among them medical statistics and the ...

Automated Debugging for Arbitrarily Long Executions

George Candea, Edouard Bugnion, Johannes Kinder, Cristian Zamfir, Baris Can Cengiz Kasikci

One of the most energy-draining and frustrating parts of software development is playing detective with elusive bugs. In this paper we argue that automated post-mortem debugging of failures is feasible for real, in-production systems with no runtime record ...
