We explain two approaches to the design of system modeling frameworks and perform their comparative analysis. The analysis familiarizes the reader with strengths and weaknesses of the approaches, and thus helps to grasp the preferences for their practical ...
Standardization can be performed only in a field in which the knowledge of the physical phenomena and of the behavior of the given installation is sufficiently known. The role of the universities is to perform research in order to clarify such these points ...
Assessing and comparing the performance of watermarking algorithms is di cult.The visibility of the watermark is an important aspect in this process.In this paper,we propose two metrics for evaluating the visual impact of video watermarks.Based on several ...
This paper presents the theoretical basis and preliminary experimental results of a new HMM model, referred to as HMM2, which can be considered as a mixture of HMMs. In this new model, the emission probabilities of the temporal (primary) HMM are estimated ...
In this paper, several approaches that can be used to improve biometric authentication applications are proposed. The idea is inspired by the ensemble approach, i.e., the use of several classifiers to solve a problem. Compared to using only one classifier, ...
The recognition rate of holographic neural synapses, performing a pattern recognition task, is significantly higher when applied to natural, rather than artificial, images. This shortcoming of artificial images can be largely compensated for, if noise is a ...
We present a framework and algorithms for multiresolution modeling of point-sampled geometry. Most of our techniques extend the key ingredients of recent multiresolution editing concepts, including geometry smoothing, simplification, and offset computation ...
TEM image simulations are used to couple the results from molecular dynamics (MD) simulations to experimental TEM images. In particular we apply this methodology to the study of defects produced during irradiation. MD simulations have shown that irradiatio ...
We describe the design, analysis, and performance of an on-line algorithm to dynamically control the frequency/voltage of a Multiple Clock Domain (MCD) microarchitecture. The MCD microarchitecture allows the frequency/voltage of micrprocessor regions to be ...
The switching kinetics in ferroelectric thin films has been intensively studied during the past decade. It is widely accepted that this kinetics is basically governed by the dynamics of domain coalescence (the Kolmogorov-Avrami-Ishibashi model). This concl ...
