Abstract:

The vertical alignment optimization problem for road design aims to generate a vertical alignment of a new road with a minimum cost, while satisfying safety and design constraints. We present a new model called multi-haul quasi network flow (MH-QNF) for vertical alignment optimization that improves the accuracy and reliability of previous mixed integer linear programming models. We evaluate the performance of the new model compared to two state-of-the-art models in the field: the complete transportation graph (CTG) and quasi network flow (QNF) models. The numerical results show that, within 1

Abstract:

The road design problem is usually split into the horizontal alignment, the vertical alignment, and the earthwork scheduling problems. Optimizing the vertical alignment assumes a predetermined horizontal alignment and changes the height of the road at different points to minimize overall construction costs, while maintaining the design requirements. The problem gets complicated because of the natural blocks like rivers, mountains, etc., in the road construction area. Existing vertical alignment models deal with the blocks before the beginning of road construction, which sometimes results in a

Abstract:

Since the Depression era there has been an evolution in parkway usage. Parkways have outlived their recreational function and now must also serve as routes to recreational facilities. Since the elemental use of parkways has drastically changed, questions of how and why beg to be answered. How has parkway design and construction changed from the Depression era to today in terms of views, alignment, vegetation, natural and cultural features, and parkway details. How is parkway design and construction different from that of typical roadways; and how does this information effect the future design

Optimization of three-dimensional road alignments is recognized as a nonlinear and nonconvex optimization problem. The development of models that fully optimize a three-dimensional road alignment problem is not yet successful, because there are many factors involved and complexities in the geometric specification of the alignment. At present, there are two optimization approaches, the models that simultaneously optimize horizontal and vertical alignments, and those employing two or more stages of optimization processes.

It always previously apply reconnaissance, preliminary survey, final location survey, then according it''s designing velocity and geometry specification to design highway by engineer experience. Therefore it must consume amount of labor to revise, expecting to achieve best designation. Because of mountainous and hilly terrain contenting up and down topography, so it needs complex geometry designation and a mount of data to calculate. It wastes of time, labor and money. Du

碩士<br>國立成功大學<br>土木工程研究所<br>86<br>Vertical alignment design is an important phase in the highway geometric design process. Even with today''s array of sophisticated computer software, determining the vertical alignment of a highway remains an art and relies mostly on the judgement of experienced engineers. The work becomes even more complicated when climbing lanes come into play. Speed of heavy vehicles is a major consideration in highway vertical alignment. Long and/or steep slopes are

At present, there is no accurate method for the cell gap and pretilt angle measurements of reflective vertical-alignment liquid crystal displays. In this thesis, we proposed a new method to determine both the cell gap and pretilt angle of reflective VA-LCDs simultaneously from phase retardation measurement. On the other hand, we investigate the influences of fringing field effects on the reflectance and the contrast ratio with different pixel sizes and pixel gaps vi

They have excellent resolution and quality, much more convenient and cheaper than CRT. The various types of LCDs have been proposed in the past, and each of them has their own advantages and disadvantages, such as Twisted Nematic (TN), In-Plane Switching (IPS), Patterned Vertical Alignment (PVA), and Multi-domain Vertical Alignment (MVA) mode.

The electric and optical properties of nanoparticle-filled VA LC cells doped with different POSS concentrations were investigated using the polarizing optical microscope (POM), capacitance-voltage (C-V) and transmittance-voltage (T-V) measurements, respectively. The aptitude of vertical alignment induced by POSS was found to be significantly influenced by the doped POSS concentrat

The mechanism of producing image sticking is very complicate, and it is not easy to analyze and overcome. However, the image sticking of LCDs can be improved by adjusting the driving to reach a minimized flicker signal, which can reduce the ions accumulation on the surfaces. The flicker measurement system adopted by current LCDs industry have limits for measuring the flicker signals of LCDs operated at the high and low gray levels. Ther

碩士<br>國立彰化師範大學<br>光電科技研究所<br>101<br>ABSTRACT Multi-domain vertical alignment (MVA) liquid crystal displays (LCDs) have wide viewing angle property and thus are commonly used in high-end display panel. However, the visible Push Mura while pressing the panel surface is the main drawback that influences the image quality of the VA LCDs. This thesis investigates the factors that cause the Push Mura of the VA LCDs. On physical condition, the obtained results indicate that the Protrusion thickness of ~ 20000 Å, baking temperature of ~ 200℃ and photo spacer thickness of ~ 31000 Å are effective in imp
