Date The final copy of this thesis has been examined by the signatories, and we find that both the content and the form meet acceptable presentation standards of scholarly work in the above mentioned discipline. Photopolymer Waveguide to Fiber Coupling via 3D Direct-Write Lithography Thesis directed by Professor Robert R. McLeod This thesis proposes and demonstrates a novel method of pigtailing...
We demonstrate experimentally that the effects of nonreciprocal elements or media that would otherwise spoil phase conjugation can be neutralized by using a tandem combination of a modal- and polarization-scrambling fiber and a phase-conjugate mirror. A theoretical model to explain the experimental results is presented.
The collagen-I gel is extensively used as a scaffold material in tissue engineering due to its ability to mimic the extracellular matrix (ECM). In this study, the mechanics of collagen-I gel is investigated using a numerical model of three-dimensional collagen network. The resulted mechanical behavior was validated against the published experimental data. Results illustrated that fiber alignmen...
Objective: This study carried out to monitor the status of nutritional management and measuring difference between present and desired feeding system in dairy cattle of rural conditions of Chaharmahal and Bakhtiari. Methods: 334 rural flocks consisting of 1442 dairy cows were selected from seven towns of this province. The experiment was lasted for in a year and using completely randomized desi...
We fabricate a free-standing few-layer molybdenum disulfide (MoS2)-polymer composite by liquid phase exfoliation of chemically pristine MoS2 crystals and use this to demonstrate a wideband tunable, ultrafast mode-locked fiber laser. Stable, picosecond pulses, tunable from 1535 nm to 1565 nm, are generated, corresponding to photon energies below the MoS2 material bandgap. These results contribut...
Figure 1: Laser wavelength dynamics The effect of self-induced laser line sweeping (or self-sweeping) was discovered in ruby laser in 1962 [1]. It was considered as an undesirable effect due to a small sweeping range. In fiber lasers the effect with broad sweeping range (more than 10 nm) was observed almost 50 years later [2]. The self-sweeping effect is caused by the formation of dynamical pha...
BACKGROUND Mineral elements present in lignocellulosic biomass feedstocks may accumulate in biorefinery process streams and cause technological problems, or alternatively can be reaped for value addition. A better understanding of the distribution of minerals in biomass in response to pretreatment factors is therefore important in relation to development of new biorefinery processes. The object...
This paper presents a highly sensitive optical biosensor and novel sample collection strategy to allow for rapid onsite screening of tuberculosis patients. The technique presented herein was field tested and envisaged to be potentially useful in third world countries with high incidences of tuberculosis or at disparate locations void of proper tuberculosis diagnostic laboratories. The rapid scr...
The use of natural fibers as reinforcement for composite materials is on the rise due to need reduce environmental damage and manufacture sustainable products. One used this purpose fique fiber. This article describes a student chair with fiber-reinforced material. To choose amount be in elaboration chair, mechanical characterization several composites different percentages fiber was carried ou...
