In this paper we consider the main problems of binary tomography, the reconstruction of binary images from few measured projections, on triangular grid. Taking into consideration the triangular grid coordinate system six natural directions can be used for measuring the projection values. For reconstructing the original image we propose a memetic and simulated annealing algorithm. We test and compare...
We present an algorithm for reconstruction of binary images represented on the triangular grid. The algorithm takes into consideration the three natural projections on the triangular grid and uses the maximum flow minimum cost algorithm for the reconstruction of the image. For testing our algorithm we used some artificial binary hexagon shaped images.
In this paper, we consider a binary hexagonal shape image on a triangular grid, with three projections along the three natural directions of the considered coordinate system. We propose an algorithm based on Ryser's theory for reconstructing the original image. In a nutshell, the first step of the reconstruction provides an image that has errorless projection values for two directions applying Ryser's...
Software projects are problematic considering their high overruns in terms of execution time and budget. In large scale projects, the monitoring activity is a very difficult task, due to the very complex relation between resources and constraints, and must be based on a well established methodology. We propose a new approach to the monitoring of large-scale software projects. Our approach is based...
The putamen, a complex structure located at the base of the forebrain [1], is connecting neuromotor fibres affected in neurodegenerative diseases, like Parkinson's Disease (PD). We study PD on a total of 47 subjects, with 22 patients clinically diagnosed with PD and 25 control cases. Using Diffusion Tensor Imaging (DTI), a type of Magnetic Resonance Imaging(MRI), we analyze the fractional anisotropy...
This paper studies the problem of data communication protocols for multiprocessor smart sensors and embedded applications with hard real-time (HRT) or critical requirements. We propose a time-triggered communication interface and set of protocols, called Predictable ARchitecture for Sensor Communication Systems (PARSECS), specifically designed to sustain, at low costs and complexity, the predictable...
