Reduced Basis Techniques For Nonlinear Conservation Laws

In this paper we present a new reduced basis technique for parametrized nonlinear scalar conservation laws in presence of shocks. The essential ingredients are an efficient algorithm to approximate the shock curve, a procedure to detect the smooth componen ...

Decentralizing the Cloud: How Can Small Data Centers Cooperate?

Karl Aberer, Rameez Rahman, Hao Zhuang

Cloud computing has become pervasive due to attractive features such as on-demand resource provisioning and elasticity. Most cloud providers are centralized entities that employ massive data centers. However, in recent times, due to increasing concerns abo ...

Model-Based Derivation, Analysis and Control of Unstable Microaerobic Steady-States-Considering Rhodospirillum rubrum as an Example

Timm Faulwasser

Microaerobic (oxygen-limited) conditions are critical for inducing many important microbial processes in industrial or environmental applications. At very low oxygen concentrations, however, the process performance often suffers from technical limitations. ...

Asymmetric Synthesis of Isoindolones by Chiral Cyclopentadienyl-Rhodium(III)-Catalyzed C-H Functionalizations

Nicolai Cramer, Baihua Ye

Directed Cp*Rh-III-catalyzed carbon-hydrogen (C-H) bond functionalizations have evolved as a powerful strategy for the construction of heterocycles. Despite their high value, the development of related asymmetric reactions is largely lagging behind due to ...

High-Order Vector Control of Grid-Connected Voltage Source Converters with LCL-Filters

Alfred Rufer, Michail Vasiladiotis, Behrooz Bahrani

This paper proposes a vector control strategy for LCL-filter-based grid-connected voltage source converters (VSCs). The proposed control strategy is inherently capable of attenuating the resonance phenomenon of such systems. This is an advantage over the e ...

Flexible triangular formation keeping of marine robotic vehicles using range measurements.

Colin Neil Jones, Jorge Miguel Dias Almeida Rodrigues Soares, Francisco Fernandes Castro Rego

This paper addresses the problem of keeping an autonomous marine vehicle in a moving triangular formation by regulating its position with respect to two leader vehicles. The follower vehicle has no prior knowledge of the path described by the leaders but h ...

Multitask Diffusion Adaptation Over Networks

Ali H. Sayed, Jie Chen

Adaptive networks are suitable for decentralized inference tasks. Recent works have intensively studied distributed optimization problems in the case where the nodes have to estimate a single optimum parameter vector collaboratively. However, there are man ...

What Future for the Urban Underground? Subsurface and Surface Potential in San Antonio, Texas

Michael Robert Doyle

The Deep City project at the École polytechnique fédérale de Lausanne has, for the past several years, been developing a method to identify and qualify the urban areas where underground development is high, particularly for human activities. The fourth dis ...

Energy-Efficient Opportunistic Collaborative Sensing

Karl Aberer, Julien Eberle, Zhixian Yan

This paper studies mobile sensing in a complete distributed and opportunistic scheme. We present a novel sensing strategy for sensing nodes without movement constraints. This strategy offers information sharing and sensor scheduling that maximizes the bene ...

A strategy for adjusting combination weights over adaptive networks

Ali H. Sayed

This work proposes a strategy to adjust the combination weights of an adaptive network in order to attain both faster convergence during the transient phase and lower mean-square-error during the steady-state phase. Optimal combination weights are designed ...
