Abstract:

Building maps within an unknown environment while keeping track of the current position is a major step to accomplish safe and autonomous robot navigation. Within the last 20 years, Simultaneous Localization And Mapping (SLAM) became a topic of great interest in robotics. The basic idea of this technique is to combine proprioceptive robot motion information with external environmental information to minimize global positioning errors. Because the robot is moving in its environment, exteroceptive data comes from different points of view and must be expressed in the same coordinate system to be

Abstract:

The Finite Element Method is a computationally expensive method used to perform engineering analyses. By performing such computations on a parallel machine using a SIMD paradigm, these analyses' run time can be drastically reduced. However, the mapping of the FEM mesh elements to the SIMD machine processing elements is an NP-complete problem. This thesis examines the use of Genetic Algorithms as a search technique to find quality solutions to the mapping problem. A hill climbing algorithm is compared to a traditional genetic algorithm, as well as a "messy" genetic algorithm. The results and co

Remotely sensed imagery is one of the most important data sources for large-scale and multi-temporal agricultural, forestry, soil, environmental, social and economic applications.

The methods can be divided into parametric and non-parametric based on the requirement of data distribution, or into global and local based on the characteristics of modeling global trends and local variability, or into unsupervised and supervised based on whether training d

Abstract:

Grid computing provides a powerful, virtual parallel system known as a computational Grid on which users can run parallel applications to solve problems quickly. However, users must be careful to allocate tasks to nodes properly because improper allocation of only one task could result in lengthy executions of applications, or even worse, applications could crash. This allocation problem is called the mapping problem, and an entity that tackles this problem is called a mapper. In this thesis, we aim to develop an efficient, practical, portable mapper.

Abstract:

It has been noted that for large solar zenith angles (θ₀ > 75°), there is some uncertainty in the retrieval scheme for determining the total column ozone amount using the Total Ozone Mapping Spectrometer (TOMS) instruments. This uncertainty arises because the current look-up table radiances were calculated by a radiative transfer algorithm using an approximate pseudo-spherical atmosphere. The pseudo-spherical code calculates the primary scatter using spherical geometry but higher order scattering is computed for a plane-parallel atmosphere.

Abstract:

In high dimensional data modeling, Multivariate Adaptive Regression Splines (MARS) is a well-known nonparametric regression technique to approximate the nonlinear relationship between a response variable and the predictors with the help of splines. MARS uses piecewise linear basis functions which are separated from each other with breaking points (knots) for function estimation. The model estimating function is generated in two stepwise procedures: forward selection and backward elimination. In the first step, a general model including too many basis functions so the knot points are generated<

Abstract:

碩士<br>世新大學<br>資訊管理學研究所(含碩專班)<br>99<br>A multi-image fusion model, similar to the method suggested by Kao et al (2008) was firstly applied in this research to create high-dynamic-range (HDR) images. It was applied in the fusion process of three differently exposed images, captured by a typical still digital camera; and then in the creation process of HDR images, for further applications in the cross-media color reproduction. The images, created by the derived fusion method, had higher HDR than those of images obtained by conventional imaging process. Moreover, they also preserves much more deta

Abstract:

碩士<br>國立清華大學<br>資訊工程學系<br>89<br>In this thesis, we propose a technology mapping algorithm for CPLD architectures. Our algorithm proceeds in two phases: mapping for single-output PLAs and packing for multiple-output PLAs. In the mapping phase, based on the results in [4], we propose a Look-Up-Table (LUT) based mapping algorithm. We will take advantage of existing LUT mapping algorithms for area and depth minimization. We also study, for a given (i, p, o)-PLA block structure, the problem of selecting the valu

Abstract:

碩士<br>銘傳大學<br>資訊工程學系碩士班<br>99<br>Cloud Computing has been a very popular topic recently. One of the applications in the Cloud Computing is virtualization. Network virtualization has emerged as a powerful way to allow multiple virtual networks, each customized to a particular application, to run on a common substrate network. Our research consists of two parts. The first is a node mapping algorithm and a link mapping algorithm. The second is a path migration algorithm. The first part focuses on how to use the proposed node mapping algorithm and link mapping algorithm to map the virtual networks

碩士<br>國立臺北科技大學<br>電腦與通訊研究所<br>94<br>The communication of variable or data between partitioned hardware and software parts will be produced in hardware-software codesign. The interface synthesis methodology will conquer the variables communication problem. The one of solution for interface synthesis is using memory mapping method. In this thesis, we propose a heuristic algorithm of memory mapping to solve variable mapping issue that includes appropriate memory port and number. Experimental results shown that our proposed algorithm under the condition of varying clock cycles and the number of va

Abstract:

碩士<br>中原大學<br>資訊工程學系<br>88<br>With the fast growth of portable electronic systems such as notebook, PDA, communication goods, low power has become an attractive issue that plays an important role to the future trend of very large scalar integrated circuit. Most of existing technology mapping algorithms, such as HeuDecomp[45], consider only the structure of a given circuit, and do not consider the functionality of the circuit. In contrast to the conventional approaches, we proposed a new algorithm consider both the structure and the functionality to further reduce the power dissipation.
