Abstract:

We present a robust iterative sparseness-constrained interpolation algorithm using 2/3D curvelet frames and Fourier-like transforms that exploits continuity along reflectors in seismic data. By choosing generic transforms, we circumvent the necessity to make parametric assumptions (e.g. through linear/parabolic Radon or demigration) regarding the shape of events in seismic data. Simulation and real data examples for data with moderately sized gaps demonstrate that our algorithm provides interpolated traces that accurately reproduce the wavelet shape as well as the AVO behavior. Our method also

Abstract:

La propagation à longue distance est un problème majeur dans les télécommunications, la navigation et la surveillance. L'objectif de cette thèse est de développer une méthode rapide pour simuler la propagation des ondes dans une atmosphère en 2D et 3D. Dans ce travail, deux contributions principales vers cet objectif sont obtenues. Tout d'abord, des méthodes auto-cohérentes,c'est-à-dire basées sur une théorie discrète de l'électromagnétisme, sont développées en 2D et 3D. Ensuite, une méthode rapide 2D basée sur les ondelettes est proposée. Pour simuler la propagation d'ondes électromagnétiques

The thesis focuses on the issue of signal processing. Using practical examples, it tries to show the use of individual signal processing operations from a practical point of view. For each of the selected signal processing operations, an application is created in MATLAB, including a graphical interface for easier operation. The division of the thesis is such that each chapter is first analyzed from a theoretical point of view, then it is shown using a practical demonstration of what the operation is used in practice. Individual applications are described here, mainly in terms of how they are h

碩士<br>國立高雄第一科技大學<br>電腦與通訊工程所<br>96<br>In recent years, it is important to apply the discrete wavelet transform to multimedia communication. Therefore, it is more serious for the hardware to realize the discrete wavelet transform. In the implementation of hardware, convolution-based operation is used to implement the discrete wavelet transform, but it needs great deal of multiplication and addition operations so that many processing elements are needed. Accordingly, the lifting-based discrete wavelet transform architecture is brought up. There was more efficient in the performance of lifting

This feature contributes to the cost control and enhancing the capability of wave monitoring since the direct impacts from the relevant environmental loads to the instrumentations can be avoided. 　　Reflections of electric-magnetic signals are represented as grey-scale images, in which information of waves can be extracted.

碩士<br>義守大學<br>電子工程學系<br>89<br>In this paper, a pipeline-parallel VLSI architecture based on the AOCA algorithm is developed for the 2D discrete periodized wavelet transform (DPWT). Due to adapting the 2D filter coefficient and using the mirror effect between the OCA operators, the new architecture needs less multipliers and bus width than the traditional architectures. The main advantages of this VLSI architecture is by using parallel data processing, so it has 100% hardware utilization and short latency. Moreover we use special homeomorphic filter, so it simplizes the boundary data processing

Instead, this dissertation presents a non- recursive algorithm for the separable 2-D DPWT, by which each stage’s decomposition can be performed independently and the 2-D DPWT coefficients of all stages can be obtained simultaneously.

ECG requires long time to record and save huge amount of data for exact diagnosis. As a result, compressing these data to efficiently store and restore is necessary. In this paper, we propose an ECG signal compression algorithm based on 2D wavelet transform (2DWT) and principal component analysis (PCA), which belongs to a lossy method.

Localized heating leads to generation of thermal Hotspots that affect performance and reliability of an Integrated Circuit(IC). Functional workloads determine the locations and temperature of hotspots on a die. Programs are classified into phases based on program execution profile. During a phase, spatial power dissipation pattern of an application remains unchanged. In this thesis, we present a systematic approach for developing a synthetic workload from a functional workload to create worst case temperature of a target hotspot in 2D and 3D IC.
