This paper studies asymmetric power assignments for various network topologies under the k-resilience criterion. We aim to minimize the total energy consumption, which is usually NP-Hard for a desired link topology. We develop a general approximation framework for various topology problems under the k-fault resilience criterion in the plane. We use it to obtain an O(k) approximation ratio for t...

Plane-wave destruction filters originate from a local plane-wave model for characterizing seismic data. These filters can be thought of as a time–distance (T -X) analog of frequency-distance (F-X) prediction-error filters and as an alternative to T -X prediction-error filters. The filters are constructed with the help of an implicit finitedifference scheme for the local plane-wave equation. Sev...

Faults of photovoltaic systems often result in an energy drop and therefore decrease the efficiency of the system. Detecting and analyzing faults is thus an important problem in the analysis of photovoltaic systems data. We consider the problem of estimating the starting time and end time of a fault, i.e. we want to locate the fault in time series data. We assume to know the power output, plane...
