Abstract:
We proposed new variance estimators for the poststratified estimator of the population total in two-stage sampling. The linearization or Taylor series variance estimator and the jackknife linearization variance estimator are popular for the poststratified estimator. The jackknife linearization variance estimator utilizes the ratio, ^Rc, which balances the weights for the poststrata while the linearization or Taylor series estimator does not. The jackknife linearization variance estimator is equivalent to Rao's (1985) adjusted variance estimator. Our proposed estimator makes use of the ratio, ^

Abstract:
Traditional single stage design optimality procedures can be used to efficiently generate data for an assumed model y = f(x<sup>(m)</sup>,b) + &#949;. The model assumptions include the form of f, the set of regressors, x<sup>(m)</sup> , and the distribution of &#949;. The nature of the response, y, often provides information about the model form (f) and the error distribution. It is more difficult to know, apriori, the specific set of regressors which will best explain the relationship between the response and a set of design (control) variables x.

Abstract:
Under heterogeneous variance, conventional optimal response surface experimental designs for estimating location models are no longer optimal. To address this deficiency. D and Q criteria appropriate under heterogeneous variance are developed. These criteria are then applied to demonstrate the improved efficiency of a proposed two-stage experimental design procedure. In the proposed procedure the first stage estimates the heterogeneous variance structure and the second stage augments the first stage to produce a total design that is Q or D-optimal for the estimated variance structure.

The overall aim of this research is to investigate the underpinning science behind constructing a practical travelling-wave thermoacoustic refrigerator.

The practical requirements were set as 400 to 500 W of cooling power at 25 K temperature difference between the inside of the enclosure and the ambient. The initial research addressed issues

In retrospect we can see that from the last century, wireless electronic technology has been in a rapid state of development. With the popularity of wireless communication, the power amplifier demand is rising. In general, magnitude, maximum noise figure, minimum noise figure, efficiency, and output power are important indicators of the amplifier. The IC industry is exploring how to reduce the additional cost and improve the high-frequency performance. Therefore, designing a strong adaptability and high cost performance of the PA has become a priority. As these technologies advance, the power

Negative effects on water quality are created by eutrophication of the world’s water resources. Mitigation measures have been implemented, but poor improvements in water quality have been observed. Two-stage ditches have the possibility to increase nutrient and sediment retention to reduce eutrophication in receiving water bodies. A two-stage ditch has floodplain terraces on each side of the ordinary main channel. The terraces are available for flooding during high water flows and enables decreases in flow velocities.

In dose-finding studies, c-optimal designs provide the most efficient design to study an interesting target dose. However, there is no guarantee that a c-optimal design that works best for estimating one specific target dose still performs well for estimating other target doses. Considering the demand in estimating multiple target dose levels, the robustness of the optimal design becomes important. In this study, the 4-parameter logistic model is adopted to describe dose-response curves. Under nonlinear models, optimal design truly depends on the pre-specified nominal parameter values. If the

碩士<br>國立交通大學<br>電機學院電信學程<br>106<br>This thesis is divided into three major parts. The first part introduces the current development of wireless communication and describes the motivation of the research. It also aims at the IEEE 802.11b/g WLAN receiver system, and details the specifications of the current IEEE 802.11b/g WLAN system. The second part of the thesis discusses the basic theory required for designing RF power amplifiers and related circuit design techniques, and verifies the correlation with theory by designing a 2.4 GHz ISM (Industrial, Scientific and Medical band) Class A RF power

Abstract:
博士<br>國立臺灣科技大學<br>化學工程系<br>95<br>The design and control of various reactive distillation systems were systematically studied for two categories of heterogeneous catalytic esterification over acidic ion-exchange resins. A series of one-stage esterification of acetic acid with five different alcohols, from methanol to amyl alcohol, was selected as model systems for the first category, while two-stage esterification of adipic acid with methanol was chosen as an illustrative example for the second category. In the process simulations, the kinetic models were taken from literature and the thermodyn

Abstract:
The United States Navy is committed to developing technology for an All-Electric Ship (AES) that promises to improve the affordability and capability of its next-generation warships. With the addition of power-intensive 21st century electrical systems, future thermal loads are projected to exceed current heat removal capacity. Furthermore, rising fuel costs necessitate a careful approach to total-ship energy management. Accordingly, the aim of this research is to develop computer tools for early-stage design of shipboard energy distribution systems. A system-level model is developed that enabl

碩士<br>國立臺灣大學<br>流行病學研究所<br>93<br>Multiple testing problem occurs when the simultaneous inference of multiple statistical tests is of interest. Two major concerns when design with multiple testing are type I error and power. In other words, a large power under limited false positive rate is the focus. However, as the number of tests increases, the overall false positive rate increases. Traditional Bonferroni’s method is conservative and controls overall false positve rate well. Consequently, its overall power is usually small. In association studies using SNP’s as genetic markers, it is common

Abstract:
碩士<br>國立清華大學<br>動力機械工程學系<br>92<br>This paper proposes a design methodology for a two-stage linear micro-feeding system that includes a coarse-feeding subsystem, a fine-feeding subsystem and positioning subsystem. The coarse stage is driven by an array of thermal actuators through a compliant amplification mechanism. This gives it the ability to generate a rapid and long range of motion. When the coarse-feeding subsystem is moved to the desired position, the system is clamped by the positioning subsystem that features two compliant bistable mechanisms. The coarse-feeding subsystem has a range o

碩士<br>國立東華大學<br>電機工程學系<br>96<br>This thesis focuses on the topics concerning about modeling and tracking control of a two-dimensional piezopositioning stage. In the system modeling, the frequency response Bode diagram of piezopositioning stage is captured by a dynamic signal analyzer (DSA). From the Bode diagram, a second-order and a third-order transfer function are established by the Curve Fitting toolbox of MATLAB computer software. On the basis of these transfer functions, the control approach for trajectory tracking of the piezopositioning stage is proposed. Instead of using the trial-and

碩士<br>國立中正大學<br>機械工程所<br>97<br>The main purpose of this thesis is to design a two-axis micro-position stage for the vacuum Lamination equipment in the ODF (One Drop Filling) manufacturing process. For the stage, the robust controller is designed such-that the behavior of micro-nano positioning can be achieved. The concepts of the technology obtained from this positioning stage will be transferred into large processing equipment such that the objective of the precision positioning can be obtained. Because of mechanism design, manufacturing error and assembling error, the stage can result in

Besides sufficiently realizing the characteristics of the system, the design of a controller is also a key point. That will improve the quality of the controller and meet with user''s requirements. Many approaches have been presented to design controllers in literatures. But most of them are often complicated. In this paper, an effective and simple algorithm, called the two-stage genetic algorithm (TSGA), is presented. It is based on the genetic algorithm and fuzzy set theory. This proposed
