Abstract:

This thesis suggests an improved parameter database implementation for one of Ericsson products. The parameter database is used during the initialization of the system as well as during the later operation. The database size is constantly growing because the parameter database is intended to be used with different hardware configurations. When a new technology platform is released, multiple revisions with additional features and functionalities are later created, resulting in introduction of new parameters or changes to their values. Ericsson provides support for old and new products. The enti

Abstract:

Mixed integer programming (MIP) problems are highly parameterized, and finding parameter settings that achieve high performance for specific types of MIP instances is challenging. This paper presents a method to find the information about how CPLEX solver parameter settings perform for the different classes of mixed integer linear programs by using designed experiments and statistical models. Fitting a model through design of experiments helps in finding the optimal region across all combinations of parameter settings. The study involves recognizing the best parameter settings that results in

Abstract:

Atrial fibrillation (AF) is a complex, multifaceted arrhythmia. Pathogenesis of AF is associated with multiple aetiologies and the mechanisms by which it is sustained and perpetuated are similarly diverse. In particular, regional heterogeneity in the electrophysiological properties of normal and pathological tissue plays a critical role in the occurrence of AF. Understanding AF in the context of electrophysiological heterogeneity requires cell-specific ionic models of electrical activity which can then be incorporated into models on larger temporal and spatial scales.

Abstract:

Thermophysical characterization of anisotropic composite materials is extremely important in the control of today fabrication processes and in the prediction of structure failure due to thermal stresses. Accuracy in the estimation of the thermal properties can be improved if the experiments are designed carefully. However, on one hand, the typically used parametric study for the design optimization is tedious and time intensive. On the other hand, commonly used gradient-based estimation methods show instabilities resulting in nonconvergence when used with models that contain correlated or near

For parameter inversion problems governed by systems of partial differential equations, such as those arising in Diffuse Optical Tomography (DOT), even the cost of repeated objective function evaluation can be overwhelming. Despite the linear (in the state variable) nature of the DOT problem, the nonlinear parameter inversion process is dominated by the computational burden of solving a large linear system for each source and frequency. To compute the Jacobian for use in Newton-type methods, an adjoint solve is required for each detector and frequency. When a three-dimensional tomography probl

However, our measurement of the rotation and translation between IMU and camera is noisy.

Abstract:

The calibration of model parameters is an important step in model development. Commonly, system output is measured, and model parameters are iteratively varied until the model output is a good match to the measured system output. Optimization algorithms are often used to identify the model parameter values. The presence of noise is difficult to avoid when physical processes are used to calibrate models due to measurement error, model structure error, and errors arising from numerical techniques and approximate solutions. Our study focuses on the effects of noise in parameter identification

One of the challenges of data mining is finding hyper-parameters for a learning algorithm that will produce the best model for a given dataset.

The advantage of using meta-heuristics over conventional optimization methods is meta-heuristics are able to find good (near optimal) solutions within a reasonable computation time.

The kernel parameter settings for SVM in training process can impact on the classification accuracy. A proper feature subset can also improve the classification efficiency and accuracy. This study hybridized the SVM with ant colony optimization (ACO) to simultaneously optimize the kernel parameters and feature subset without degrading the classification accuracy. Using the feature importance and pheromones information to determine the transition probability. Using the class

Abstract:

碩士<br>逢甲大學<br>材料與製造工程所<br>94<br>The goal of this article is to study the stress concentration effect during the inner lead bonding process for tape automated bonding technology. The finite element method is employed to conduct the parametric study for forming the lead. The optimal parameter of time versus compression loading through the comparison between one-stage compression and two-stage compression process is proposed. Furthermore, the stress distribution on the bump and lead under different compressing time is considered at the same time for the singe lead simulating model. Based on the s

碩士<br>國立中興大學<br>機械工程學系所<br>96<br>This thesis studies the stresses in step chain subjected to differenert loadings. When the link is assembled,the interference fit occures between the link plate and the pin or bush.This interference fit produce stresses in the link before subjecting to external loading.Upon moving to the tight side,the link takes the maximum loading which includes the external loading and the loading due to interference fit.When the link enters the slake side,the external loading approaches zero.Therefore in a complete cycle,the loading applied to a link varies between two valu

Abstract:

博士<br>國立交通大學<br>工業工程與管理系<br>90<br>Parameter design is advocated to design a product by selecting the optimum conditions of control factors (factors which we can control) so that the product is least sensitive to uncontrollable factors (noise factors) such as wear, aging, and ambient conditions. The manufacturing interests which are created concern technological advances and the marketability of products and services. Thus, parameter design questions interact constantly with the realm of continuous improvement. Conventionally, Taguchi methods have been widely used in industry; however, this met

碩士<br>國立屏東科技大學<br>車輛工程系所<br>97<br>The works of this thesis are divided into two parts. Firstly, a dynamic simulation model for hybrid electric scooters (HES) is developed. Attention is paid to the prediction of key parameters of the scooter such as the engine speed, CVT gear ratio, and fuel consumption on the ECE40 drive cycle in order to evaluate the performance of the HES. The scooter studied in this research consists of an electronically controlled fuel injection internal combustion engine (ICE), a generator, clutch, final drive gears, a power assistant motor, and a mechanical-type continu
