The present thesis consists of four parts, all connected to sensor array signal processing in a wide sense. The rst part covers the optimal solution to a commonly occurring matrix optimization problem and the resulting implications for the best linear unbiased estimator (BLUE) and for spatial and temporal lter design. Non-parametric spectral estimation is covered in the second part. Here, we in...

This paper presents a parametric stability study of groin, or cross vaults, structural element widely used in old masonry construction, particularly Gothic architecture. The vaults’ is measured using the geometric safety factor (GSF), computed by evaluating structure’s minimum thickness through thrust network analysis (TNA). obtained formulating and solving specific constrained nonlinear optimi...

In this paper, we provide a detailed comparison between various models that have been provided in literature for predicting faults in the software testing process. They are commonly known as software reliability models. In this paper we discuss an experimental evaluation of software reliability analysis using parametric and nonparametric methods. The experimental data set for different, small a...

Real-time applications are playing an increasingly significant role in our life. The cost and risk involved in their design leads to the need for a correct and robust modelling of the system before its deployment. Many approaches have been proposed to verify the schedulability of real-time task system. A frequent limitation is that they force the task activation to restrictive patterns (e.g. pe...

eight faba bean genotypes and one local (barkat) as control were evaluated for three successive years (2000-2003) in a randomized complete block design (rcbd) with four replications at gorgan agricultural research station. this study was carried out to determine the morphological traits, yield components and yield stability to select the best genotypes. simple and combined analysis of variance ...
