Abstract:

Random fiber lasers, a new type of fiber laser that uses disordered medium to provide distributed feedback, have drawn considerable interest in the photonics community over the past ten years. Stimulated Brillouin scattering (SBS), with a typical narrow spectral width of ~100 MHz, provides an important gain mechanism for random fiber lasers. Brillouin random fiber laser (BRFL) has shown excellent advantages in generating highly coherent photons and in ultrasound sensing. However, the accompanied large intensity noise in BRFLs hinders its further performance improvement and practical applicatio

Abstract:

Mechanical pulps are used in paper products such as magazine or news grade printing papers or paperboard. Mechanical pulping gives a high yield; nearly everything in the tree except the bark is used in the paper. This means that mechanical pulping consumes much less wood than chemical pulping, especially to produce a unit area of printing surface. A drawback of mechanical pulp production is the high amounts of electrical energy needed to separate and refine the fibers to a given fiber quality. Mechanical pulps are often produced from slow growing spruce trees of forests in the northern hemisph

Abstract:

Liquefaction of soil is one of the major contributing factors for damages of infrastructures and utility services during earthquake. Liquefaction occurs when short strong shaking creates undrained loading condition in saturated soil deposit thereby increases pore water pressure, which eventually equals the effective confining pressure resulting in significant reduction in shear strength and bearing capacity of soil deposit. Several studies have been conducted to investigate the effect of polypropylene fiber on sand deposit as a measure to prevent liquefaction but most of them are based on stat

Abstract:

Frequency and intensity noise are characterized for Erbium-Doped Fiber and Brillouin random lasers based on Rayleigh distributed feedback mechanism. We propose a theoretical model for the frequency noise of an Er-doped fiber random lasers using the property of random phase modulations from multiple scattering points in ultra-long fibers. We find that the Rayleigh feedback suppresses the noise at higher frequencies by introducing a Lorentzian envelope over the thermal frequency noise of a long fiber cavity. The theoretical model and measured frequency noise agree quantitatively with two fitting

The development of sensing devices is one of the instrumentation fields that has grown rapidly in the last decade. Corresponding to the swift advance in the development of microelectronic sensors, optical fibre sensors are widely investigated because of their advantageous properties over the electronics sensors such as their wavelength multiplexing capability and high sensitivity to temperature, pressure, strain, vibration and acoustic emission. Moreover, optical fibre sensors are more attractive than the electronics sensors as they can perform distributed sensing, in terms of covering a reaso

In the past, both systematically and randomly reinforced soils have been used widely in civil and geotechnical structures. Randomly reinforced-soils using fibres exhibit advantages over systematically reinforced-soils because systematic reinforcements may result in weak planes within the soil mass. Randomly distributed reinforcements are also easier to apply and maintain for some applications. Previous researchers have studied the strength, compa

Conventionally, LPFGs are fabricated by use of photosensitive fibers and ultra violet lasers. Recently, non-ultraviolet (UV) based fabrication methods, such as arc discharge or CO2 laser, have attracted more and more attentions due to its much lower cost. By heating the fibe

Abstract:

碩士<br>中臺科技大學<br>醫學工程暨材料研究所<br>103<br>Calcium phosphate bone cement (CPC) is one material for artificial bone scaffolds, and has desirable biocompatibility. However, CPC is brittle and does not have a porous structure, which is disadvantageous for cell growth. This study aims to create CPC with a porous structure for cell growth via the addition of porogen that have different particle sizes and blending ratios. Moreover, fibers that are used in the biomedical field are also incorporated in order to improve the toughness and brittle fracture of CPC. The porous fiber-embedded bone scaffolds are t

Abstract:

碩士<br>雲林科技大學<br>機械工程系碩士班<br>98<br>While a variety of data and reports are available from the researches on Poly Lactic Acid (PLA), the application of PLA material is still not well developed due to some poor performance in heat resistance, impact resistance and flame retardancy. In this study, bamboo fibers are used to be reinforced material with PLA and supposed to provide a typical fiber-reinforcement that may lead to improvement in the mechanical properties of the composites. Hopefully, improvement is expected in heat resistance, impact resistance, and flame retardancy. To achieve our goal

The experimental methods are adopted to study the performance and characteristics of the cell under certain operational conditions. In order to obtain the permeability of carbon fiber bipolar plates the pressure drops and flow rates are measured on the two sides of the carbon fiber bunch. A test device has been developed to separate the gas of the two sides so that the gas can only flow through the gaps between carbon fibers. Additionally, the gas pressures
