Network reconstruction, i.e., obtaining network structure from data, is a central theme in systems biology, economics and engineering. In some previous work, we introduced dynamical structure functions as a tool for posing and solving the problem of network reconstruction between measured states. While recovering the network structure between hidden states is not possible since they are not mea...

background: with increasing age, some changes appeared in specifications of vessels which including dimensions and elasticity in their. the changes in parameters such as resistance, inertance and compliance vessels appear and eventually changes in the environmental pulse releases are in circulation. these changes clearly appear in specification of photoplethysmogram particularly in the size and...

In the paper we present a new approach to the image reconstruction problem based on evolution algorithms and cellular automata. Two-dimensional, nine state cellular automata with the Moore neighbourhood perform reconstruction of an image presenting a human face. Large space of automata rules is searched through efficiently by the genetic algorithm (GA), which finds a good quality rule. The expe...

Generalized Hermite polynomials in two variables are employed f o r the reconstruction of images from a knowledge of their zero crossing contours. The problem of reconstruction of signals as functions of two variables is not a mere extension of that of a single variable. This is a consequence of the fact that the spatial and spectral characteristics of two-variable functions are quite distinct ...

We present a fast iterative FFT-based reconstruction algorithm that allows for nonparallel redshift-space distortions (RSD). We test our algorithm on both N-body dark matter simulations and mock distributions of galaxies designed to replicate galaxy survey conditions. We compare solenoidal and irrotational components of the redshift distortion and show that an approximation of this distortion l...

Over the last years the number of cyber-physical systems that provide critical functionality has increased continuously. Ensuring the correct behavior of those systems is essential to prevent potentially catastrophic malfunctions. This dissertation is about online model checking, a dynamic variant of model checking that can provide safety guarantees even if accurate long-term modeling of a syst...

Recently the new field of parallel imaging accusation has the potential to revolutionize the field of fast MR imaging. The SPACE RIP technique is one of the parallel imaging methods which uses multiple receiver coil and utilizes the sensitivity profile information from a number of receiver coils in order to reduce the acquisition time. The image reconstruction problem of SPACE RIP is a computat...

We introduce a novel noniterative algorithm for the fast and accurate reconstruction of nonuniformly sampled MRI data. The proposed scheme derives the reconstructed image as the nonuniform inverse Fourier transform of a compensated dataset. We derive each sample in the compensated dataset as a weighted linear combination of a few measured k-space samples. The specific k-space samples and the we...
