Abstract:
Satellites are some of the most difficult links to exploit in a Quality of Service (QoS) sensitive network, largely due to their high latency, variable-bandwidth and low-bandwidth nature. Central management of shared links has been shown to provide efficiency gains and enhanced QoS by effectively allocating resources according to reservations and dynamic resource availability. In a modern network, segregated by secure gateways and tunnels such as provided by IPsec, central management appears impossible to implement due to the barriers created between a global Dynamic Bandwidth Resource Allocat

Abstract:
Vernier Tuned Distributed Bragg Reflector (VT-DBR) lasers have had great success in the field of Swept-Source Optical Coherence Tomography (SS-OCT) due to their continuous and nearly 40 nm wavelength tuning range in a single longitudinal mode. Fast sweeps allow for real time imaging with micrometer resolution at a distance of a few centimeters. While this laser has proven quite useful as a medical imaging tool via OCT, it has yet to similarly prove itself for general light detection and ranging (LIDAR) applications due to range limitations that arise from a finite laser coherence length.

Abstract:
In eukaryotes the coding regions of most genes are interrupted by introns that must be removed by splicing to form a coding mRNA. However, while the splicing mechanism has received a lot of attention, much less is known about the metabolism of introns. This is partly due to the difficulties in studying introns as both aberrantly spliced transcripts and spliced introns are rapidly degraded. In this study, I have analysed intron metabolism in two respects: first I have investigated how introns are degraded following the completion of splicing. Second, I investigate the fate of transcripts, in wh

Abstract:
SG-DBR lasers look to solve many problems associated with present OCT sources by being cost effective, smaller in size, more robust, and by operating at faster repetition rates. Swept Source Optical Coherence Tomography (SS-OCT) requires a tunable laser source that exhibits linear frequency sweeps, large frequency spans, and high repetition rates. This work accomplishes this by using four synchronized waveforms sent to the input of a Sampled Grating-Distributed Bragg Reflector (SG-DBR) laser.

Constructed entirely on a semiconductor substrate, SG-DBR lasers require four synchronized waveforms to modulate the output wavelength and intensity.

From the interferometer, the difference frequency is detected and amplified. The optical difference frequency takes on the form of a microwave signal that can be seen on an electrical spectrum analyzer. The hardware structure of

Abstract:
碩士<br>國立交通大學<br>電子物理系<br>91<br>In this thesis, we propose a method to achieve a narrow band-pass optical filter using cascaded Distributed-Bragg-Reflectors (DBRs) and optical cavity, which construct a Fabry-Perot-like interferometry. Firstly, we analyze the traditional thin-film coating multi-layer optical filter by the use of transfer matrix method. The results can give us a guide how to design an optical narrow band-pass filter with nearly rectangular transmission spectrum. Secondly, by using the coupled-wave analyses of a volume hologram, we derive the scattering matrix method to analyses t

For AlxGa1-xAs layers embedded in multi-layer structure, a stable oxidation process is achieved by precisely control the flow rate of carrier gas, oxidation temperature and oxidation period, the thickness of AlxGa1-xAs layers, etc. The oxidation rate of the DBR implanted with oxygen ions will be enhanced at the temperature range of 350~450℃. We thought the enhanced oxidation rate is dominantly resulte

Especially in the metal processing industry, companies often face the uncertain processing capacity in the production process, operations scheduling becomes even more complicated and the ERP and the SCM systems usually cannot effectively keep the overall performance stable. Most studies on operations scheduling base their scheduling on fixed-premise machine outputs, which cannot meet the characteristics of such dynamic production systems. This study uses the The

The design of the chip becomes more and more complicated. In order to solve increased complexity, the concept of the silicon intellectual property (SIP) modules be extensively used. Hence, the SIP modules might be designed by a lot of different companies or offered with different departments. So, the companies which develop SIP modules can make good at their development and verification of products up to th

A good manufacturing system is enable to reduce production cycle time and raises the reliability of due day. In order to reach the objectives, manufacturing system must overcome the effects of various variable events, random fluctuation on production line, and minimum of the production cost as well.

Abstract:
Wavelength tunable devices are required in many fields like spectroscopy of gases, biomedical absorption experiments, wavelength division multiplexing in optical data networks, among others. Usually the devices are limited by the technology implemented to change the transmitted frequencies and are specific to their usage scenario. Thus extending the regime in which a single device can function, will reduce the need for many different devices with a narrow application window. For example, having a tunable laser for telecommunication networks around 1550 nm, that can support both L- and C-bands

He also focused on Due Date Performance(DDP) for products in many factories . In 2008, in his Standing On The Shoulders Of Giants, he raised an important hypothesis.

In order to improve the junction temperature and reduce the shading effect of electrodes, the flip-chip technology for LED package was also proposed and developed. The light will emit from substrate side surface for flip-chip packaged LEDs. The output intensity can be further enhanced if a reflector is deposited on the top surface of LEDs.

They claimed that the market demand was the constraint of production system. They considered that there was no need to do the capacity constrained resource (CCR) scheduling if we could obey the CCR’s Planned Load (PL), which included well-organized confirm orders, release orders and priority management. That would make production management become easier. After developing and practicing for six or seven years, Schragenheim brought up the implementation
