This article presents a method for decomposing a temporal sequence of photoelectron spectra into a parameter set reflecting the positions, amplitudes, and widths of the peaks. Since the peaks exhibit a slow evolution with time, we propose to take into account this temporal information by jointly decomposing the whole sequence. To this end, we have developed a Bayesian model where a Gaussian Markov...
Leaf chlorophyll content provides valuable information about physiological status of plants. NIR spectroscopy measurement makes it possible to quickly and non-destructively assess the chlorophyll content in leaves. Our objective was to investigate the spectral behavior of the relationship between reflectance and chlorophyll content and to develop a technique for non-destructive chlorophyll estimation...
Grid scheduling is a key problem for grid to improve the resource management and application performance. It has been proven to be a NP-hard problem for the computation of optimal grid schedules, which is responsible to allocate resources to user jobs with the objective such as minimizing the completion time or cost. Therefore, it is more difficult for Grid scheduling system to cope with the dynamically...
The difficulty for accurate determination of the angles of arrival (AOA) of signals arises from the optimization of likelihood functions of high dimension. Usually, a gradient-based technique is employed to find the optimum of the function. However, this method requires heavy computational work and the differentiability of the likelihood function. This paper presents two gradient-free methods: One...
