Three-dimensional fluvial-deltaic sequence stratigraphy Pliocene-Recent Muda Formation, Belida Field, West Natuna Basin, IndonesiaDarmadi, Yan 25 April 2007 (has links)
The Pliocene-Recent Muda formation is essentially undeformed in the West
Natuna Basin, and excellent resolution of this interval on three-dimensional seismic data
in Belida Field allows detailed interpretation of component fluvial-deltaic systems.
Detailed interpretation of seismic time slice and seismic sections along with seismic
facies analysis, horizon mapping, and extraction of seismic attributes provide the basis to
construct a sequence stratigraphic framework and determine patterns for sediment
dispersal and accumulation.
The Muda interval contains five third-order sequences, with depositional
environments confined to the shelf and consisting mainly of fluvial elements. Sequence
boundaries (SB) apparently result from major sea level falls, since there was no tectonic
uplift and the field underwent only regional slow subsidence during sedimentation of the
study interval.
Sea level fluctuation also caused changes in fluvial patterns. Analysis of
changing channel patterns indicates that major systems tracts relate to specific channel
patterns. The Lowstand Systems Tract (LST) is generally dominated by larger channel dimensions and low sinuosity channel patterns. The Transgressive Systems Tract (TST)
typically contains relatively smaller channels with high sinuosity. Channels in the
Highstand Systems Tract (HST) generally show moderate sinuosity channels and are
intermediate in size, larger than TST channels but smaller than LST channels. Crossplots
of stratigraphic position and channel morphology indicate that within the transition from
LST-TST, channel dimensions (width and thickness) generally decrease and channel
sinuosity generally increases.
High sinuosity, meandering and anastomosing channels are generally found near
the maximum flooding surface. Low sinuosity channels occur within the HST-SB-LST
succession, with the exception of higher sinuosity meandering channels evolving inside
valleys. Larger, lower sinuosity channels result from high gradient and high discharge
associated with stream piracy. Smaller, high-sinuosity channels result from low gradient
and small discharge.
Extraction of seismic attributes such as RMS Amplitude and Average Reflection
Strength show these depositional features in greater detail. In the Belida Field area,
lowstand channels were found to comprise the greatest volume of sandstone bodies.
Seismic delineation of the distribution and morphology of these channel systems provides
critical input for reservoir modeling and volumetric analysis.

Stability Analysis of Three-Wheel StrollerLee, Chia-yun 31 July 2008 (has links)
¡@¡@This study provides static and dynamic analysis of three-wheel stroller which is marketed. The model of stroller is built by computer- aided design software SolidWorks for perform static analysis on finite element analysis software ANSYS and mechanism¡¦s dynamic analysis on directed computer-aided mechanism analysis software COSMOSMotion.
¡@¡@It is important of stroller safety because it carry tender babies. The stroller should be examined carefully with three-wheel stroller always used on outdoor. CNS 6263 provides the standard for the safety test on the structure of the stroller, which includes a static analysis. In order to offer absolute safety for stroller, CNS uses a high standard to test the sample. For the market permission, the stroller needs to pass the CNS test, company always let stroller too strong to pass the test, and that will let the volume and weight too large to burden with cost. In this thesis, the researcher discussed the different on stroller between the traditional design and the CNS standard design. He also made an assumption the check if the stroller is overdesign.
¡@¡@A three-wheel stroller is a jogging stroller, and it is usually used on high velocity. Manufacturer should consider its steady, especially when the mass center of three-wheel stroller is usually too high. Dynamic analysis in this study will discuss the effect on the stroller when the forces of user are applied on the stroller. By the rollover formula of the three-wheel car, this study modified the program for three-wheel stroller in order to consider the influence of the force on the stroller. Comparing the results between the simulation of software and the calculation of the rollover function of three-wheel stroller, this study provides models for designers to prevent the rollover from the stroller.

Numerical study for a micro-PEMFCLin, Kuan-Wen 21 August 2008 (has links)
A three dimensional numerical model for a micro proton exchange membrane fuel cell was developed to simulate the concentration distribution of the fuel gas, and analyze the flow field and current field in the fuel cell. Finite control volume scheme with SIMPLEC algorithm was employed in the numerical method.
Various operating conditions on the performance of the fuel cell were studied. It was shown that the concentration of oxygen at the cathode can strongly influence the cell performance. Increase the operating temperature and the pressure of the inlet gas can improve the performance of the fuel cell.

The Impact of ¡§Mini-Three-Links¡¨ Policy on Kinmen Economic Development: An Empirical StudyWang, Hsiang-wei 10 September 2008 (has links)
Since the trial implementation of the ¡§Mini-Three-Links¡¨ policy in Kinmen on January 1, 2001, the government has in the past seven years adjusted relevant policies after step-by-step reviews based on the principle of promoting related matters in a sequential and orderly manner. The scale of the ¡§Mini-Three-Links¡¨ has expanded day by day, which has not only provided convenience to the lives of the people in Kinmen, but also provided convenient channels to the Taiwanese people traveling to and from the Mainland China. As of July 2008, the total number of people traveling across the Strait via the ¡§Mini-Three-Links¡¨ route has reached 1.586 million (both gross exit and gross entry) and the number of sailings via this route has reached 23,353.
