title: Intermediate bosonic metallic state in the superconductor-insulator transition

description: Whether a metallic ground state exists in a two-dimensional system beyond Anderson localization remains an unresolved question. Here, we study how quantum phase coherence evolves across superconductor-metal-insulator transitions via magneto-conductance quantum oscillations in nanopatterned high-temperature superconducting films. We tune the degree of phase coherence by varying the etching time of our films. Between the superconducting and insulating regimes, we detect a robust intervening anomalous metallic state characterized by saturating resistance and oscillation amplitude at low temperatures. Our measurements suggest that the anomalous metallic state is bosonic and that the saturation of phase coherence plays a prominent role in its formation.

title: Le tragique Dans Mort d’un personnage de Jean Giono

description: Ce présent travail a pour objectif d’analyser le tragique dans Mort d’un personnage de Jean Giono. L’étude se compose de trois parties : le choix des techniques narratives pour le tragique, le thème de la quête existentielle et l’interprétation symbolique du titre de roman lié au théâtre de la mort. Tout d’abord, la focalisation interne et le style indirect libre sont choisis pour que le protagoniste, Angelo III, raconte son souvenir de sa grand-mère, Pauline. La narration rétrospective permet au narrateur-témoin de remonter dans le passé à la fois pour relater les événements et pour en porter ses jugements. Le ton tragique du roman est ainsi orienté et renforcé par le point de vue du narrateur vis-à-vis des mystères indéchiffrables de l’héroïne. Ensuite, le tragique est mis en évidence avec la quête existentielle de Pauline et ses descendants. Poussés par le vide de l’existence, chacun de cette famille apaise ce mal de vivre à sa façon. Pauline et son petit-fils tentent d’évoquer la figure illusoire pour substituer l’être cher. M. Pardi, son fils, s’efforce de faire preuve de son existence avec le dévouement pour les aveugles et l’amour pour sa mère. Malgré toutes ses tentatives, son être semble transparent, ce qui vient en effet de son état d’enfant naturel, rejeté d’un point de vue social. Enfin, le titre Mort d’un personnage incite à étudier l’aspect théâtral dans le roman. Le lecteur semble assister à un spectacle tragique sur scène avec les conflits existentiels, entre la vie et la mort, qui s’emparent de l’héroïne. Son caractère mort-vivant amène ses descendants à vivre le tragique dans le quotidien. Ce n'est que son décès qui les libère et leur permet de reprendre le rythme de la vie.

title: Gold nanoparticle-based colorimetric analysis of protein content in milk

description: An easy-to-practice colorimetric analysis of milk protein content has been developed. The assay relies on stabilization power of protein that can inhibit gold nanoparticles (AuNPs) aggregation induced by hydrochloric acid. In the presence of milk protein, the assay gave explicit red to blue color depending on protein concentration. Since the appeared colors, which emerge from localized surface plasmon resonance phenomenon, can be observed by naked-eye sensing or UV-visible spectroscopy, protein concentration of the sample could be evaluated. With the optimized condition, the assay is so sensitive that it can distinguish nearby protein concentrations in the same order of magnitude by naked eye sensing with adjustable sensitive range in 2.93x10⁻¹ to 2.93x10⁻³ mg/mL. In the assay, extra accuracy can be achieved using UV-visible spectroscopy to measure λ[subscript max] or intensity ratio at maxima and at 520 nm. Interfering substance study showed that starch, lactose, table sugar, melamine, and sodium chloride cannot deceive the assay. The developed assay is very simple, requires only 6 minutes analysis time and does not need extraction process.

title: The association between corporate governance mechanisms and stock investment risk through accruals quality : empirical evidence from Thailand

description: This study investigates the association between corporate governance mechanisms and stock investment risk through accruals quality during the period of 2007 to 2009 of listed non-financial firms in Thailand by using multiple regression analysis. The corporate governance mechanisms consist of corporate governance index, family ownership, institutional ownership, the Herfindahl index, industry-adjusted price-cost margin and media coverage. The stock investment risk defines as idiosyncratic risk and total risk. Besides, this study uses the measure quality of accounting information, i.e. accruals quality as a mediating variable. The results show that firms with higher accruals quality have lower idiosyncratic risk and total risk, and that accruals quality is a mediating variable between corporate governance mechanisms and stock investment risks. Firms with increased corporate governance index and family ownership concentration have higher accruals quality and lower stock investment risk. This study also indicates firm with higher proportion of institutional investors have lower stock investment risk. Besides, the results show that firms enjoying higher market power have higher accruals quality than firms in competitive product market. Firms with higher marker power have lower stock investment risk. Finally, firms with more media coverage have lower accruals quality and higher stock investment risk. Overall, these results show that corporate governance mechanisms directly decrease the stock investment risk and indirectly decrease stock investment risk through the higher quality of accounting information, i.e. accruals quality.

title: Large scale flat panel airlift photobioreactor for high density cultivation of vegetative cell, Haematococcus pluvialis

description: The cultivation of green vegetative cells of Haematococcus pluvialis NIES-144 was carried out in flat panel airlift photobioreactors (FP-ALPBRs) of different sizes, i.e. 17, 50, 90 and 200L, operated in the evaporative room where the temperature was controlled at 27±3℃. Normal cultivation was carried out with a superficial gas velocity (U[subscript sg]) of 0.4 cm s-1 mixed with 1%vol CO₂, and a ratio of downcomer and riser cross sectional area (A[subscript d] / A[subscript r]) of 0.4. The hydrodynamic characteristics for FP-ALPBR system, i.e. liquid velocity and overall volumetric gas-liquid mass transfer, were also investigated. The hydrodynamic study reveals that the system with (A[subscript d] / A[subscript r]) of 0.4 provided the lowest liquid velocity for 17L ALPBR system (U[subscript l] ranged from 1.2-6.3 cms⁻¹), and the greatest amount of overall volumetric mass transfer coefficient (K[subscript L]a ranged from 0.000358 to 0.0066 s⁻¹). This condition provides the lowest shear stress which makes it suitable for the green vegetative stage of H. pluvialis. Several alternative growth options were proposed in order to enhance mass production of green vegetative cell of H. pluvialis and also to cut down the total operating cost for such algal cultivation. The use of natural lighting was inevitable to avoid the high electricity cost, and replacing artificial lighting with natural light was found to decrease the total production cost by as much as 307 US$ per 0.5 kg dry cell in the 50L FP-ALPBR. Nevertheless, the lack of control of diurnal light intensity resulted in a drop in the growth performance with cell density decreasing from 387 x 104 to 140 x 104 cell mL⁻¹, and specific growth rate from 0.63 to 0.53 day⁻¹. Reactor sizes (under natural light operation) appeared to be significant for the profitability of the system, and enlarging the FP-ALPBR from 17 to 200L required significantly lower total costs of production per year (121 US$ per 0.5 kg dry cell for 200L culture when compared to 197 US$ per 0.5 kg dry cell for the 17L system). Unfortunately this had to be compensated by a drop in the growth performance with cell density decreasing from 290 x 104 to 147 x 104 cell mL⁻¹ and specific growth rate from 0.49 to 0.47 day⁻¹. Finally, the reuse of spent medium (under natural light operation) with proper replenishment of nutrients caused an unexpected around 30 % drop in the growth rate and did not seem to provide an attractive response as the total cost per 0.5 kg dry cell was only saved by 8 US$ a year.

title: Comparison of important factors which explain credit default swap premium variations : a forward-looking perspective

description: In modern financial markets, the credit default swap (CDS) market has supplanted the bond market as the industry gauge for a borrower's credit quality. Therefore, it is very important to understand factors which explain CDS premium variations. That is because if we understand important factors which explain CDS premium variations, we can focus on the important factors to develop better CDS pricing models. There have been a lot of approaches to value CDS contracts. Each approach assumes some factor(s) which explain CDS premium variations such as related security prices, time trend and correlation between probability of default and recovery rate, etc. To the best of our knowledge there have been no studies comparing the contribution to explaining CDS premium variations of these factors during the credit crisis in the US in 2008-2009. That is partly because when doing so we need a model which can handle all of the factors at the same time. Most of the CDS valuation models cannot incorporate many different features simultaneously. We improve Das and Hanouna (2009)’s jump-to-default model in which many different features can be handled simultaneously. In the study, we found that the time trend is the most powerful feature to explain the CDS premium variations. We also compare market CDS premiums with the fitted premiums from our model in which we include all of the features in our study to check how well our model performs. It can be observed from the results that our model can be used to forecast the CDS spreads very well in all time to maturity CDS contracts except when the CDS market is very volatile and there is a big jump in CDS premiums.

title: Robust image reconstruction algorithm in the presence of gaussian and impulsive noise for compressed sensing

description: The Compressed Sensing (CS) reconstruction methods robust to Gaussian and/or impulsive noise are proposed in this dissertation. In the first part, the reconstruction in the Gaussian noise environment is proposed. The compressed measurement signal is subsampled for L times to create the ensemble of L compressed measurement signals. Orthogonal Matching Pursuit with Partially Known Support (OMP-PKS) is applied to each signal in the ensemble to reconstruct L noisy outputs. The L noisy outputs are then averaged for Gaussian denoising. The proposed method was evaluated on 40 test images and found to improve both PSNR and visual quality of the reconstructed results. In the second part of this dissertation, the reconstruction in the impulsive noise environment is investigated. In conventional methods, the impulsive noise tolerance is acquired by using the Lorentzian norm of robust statistics. The optimization of the robust statistic function is iterative and usually requires complex parameter adjustments. In this part, the impulsive noise rejection for the compressed measurement signal with the design for image reconstruction is proposed. It is used as the preprocessing for any compressed sensing reconstruction given that the sparsified version of the signal is obtained by utilizing octave-tree discrete wavelet transform with db8 as the mother wavelet. The presence of impulsive noise is detected from the energy distribution of the reconstructed sparse signal. After the noise removal, the noise corrupted coefficients are estimated. Moreover, the proposed method requires neither complex optimization nor complex parameter adjustments.In addition, the two proposed methods can be combined to create the reconstruction robust to both Gaussian and impulsive noise.

title: Development of high performance PMDA-modified polybenzoxazine composites reinforced with carbon fiber

description: This research aims to develop a high performance composite of carbon fiber (CF)-reinforced polybenzoxazine (PBA-a) modiﬁed with pyromellitic dianhydride (PMDA). The effect of the carbon fiber and PMDA contents on flammability, mechanical, and thermal properties of the composites were investigated. The 65wt% CF-reinforced PBA-a:PMDA matrix provided a maximum packing, resulting in a remarkable increase in mechanical and thermal properties. The flammability of the composites made from 65wt% of carbon fiber and PBA-a modified with PMDA at various of PMDA contents was examined by limiting oxygen index (LOI) and UL-94 vertical tests. The results showed that the LOI values increased from 26.0 for 65wt% CF/PBA-a to 49.5 for 65wt% CF/PBA-a:PMDA and an improvement in fire resistance of all 65wt% CF/PBA-a:PMDA composites as thin as 1.0 mm was also achieved the maximum V-0 fire resistant classification. In addition, the incorporation of the PMDA into PBA-a matrix significantly enhanced the glass transition temperature (T[subscript g]) and the storage modulus (E') values of 65wt% CF/PBA-a:PMDA composites rather than those of the 65wt% CF/PBA-a. The T[subscript g] values and storage moduli at 35℃ of the obtained 65wt% CF/PBA-a:PMDA composites were found to have relatively high value up to 237℃ and 46 GPa, respectively, while those values of the 65wt% CF/PBA-a is approximately 183℃ and 41 GPa, respectively. From TGA results, all 65wt% CF/PBA-a:PMDA composites exhibited relatively high degradation temperature up to 498℃ and substantial enhancement in char yield with a value of up to 82%, which are somewhat higher compared to those of the 65wt% CF/PBA-a composite, i.e. 405℃ and 75.7%, respectively. From the improvement of flame retardant, mechanical and thermal properties, it was found that the obtained CF/PBA-a:PMDA composites exhibited high potential applications in advanced composite materials that required mechanical integrity and self-extinguishing property.

title: Coal-water slurry using dispersants synthesized from cashew nut shell liquid

description: The purpose of this study was to synthesize three anionic dispersants for the formulation of highly concentrated coal-water slurry from cashew nut shell liquid. The performance of the three synthesized dispersants, which are diethanolamine anacardate, triethanolamine anacardate and cardanol-formaldehyde sulfonate, were investigated and compared with a commercial dispersant, sodium lignosulfonate. It was found that cardanol-formaldehyde sulfonate as a new dispersant, synthesized from sulfomethylation reaction of cardanol, formaldehyde and sodium sulfite, was more efficient dispersant for coal-water slurry application than diethanolamine anacardate and triethanolamine anacardate. In the presence of 1.0-1.8 wt% of cardanol-formaldehyde sulfonate, coal-water slurry containing 50% weight fraction of coal could be achieved. Cardanol-formaldehyde sulfonate had a surface activity with the surface tension of 51 mN/m. In addition, the zeta potential was substantially increased with concomitant shift of the progressive dispersant concentration. The slurry stability for a period of as long as 1 month gave below 50% of penetration ratio in contrast to below 30% in the case of bare coal-water slurry. As compared with a commercial dispersant, it was found that cardanol-formaldehyde sulfonate gave similar properties to those of sodium lignosulfonate, within acceptable ranges.

title: Operational risk management for motorcycle parts factory

description: The application of operational risk management is conducted in this research to control operational risks for motorcycle parts factory. This research has developed from the risk identification within manufacturing process of 3 groups of product, Sprocket Gear, Collar and Meter Gear from process of Raw Material Preparation, Machining, Gearing, until Grinding. Then, the risk analysis and evaluation has been applied to classify those risks into 4 levels. This research has determined the treatment for managing the high and emergency risks which named as major risk events. The study mainly used the Fault Tree Analysis (FTA) as the technique for analyzing the root cause of risks. Base on the study, it was found that there were 4 groups of failure that impact to product quality. They include 1) Misleading if measurement from human error 2) Diameter and Shape failure from machine error 3) Material changing from material specification 4) Roughness error from inappropriate method. Those failures led to root of causes of those 12 major risk events. Consequently, those 12 major risks had an effect to the number of defects that over company’s targets. The risk treatment plan had been established for mitigation those major risks. Those plans include training, preventive maintenance, skill evaluation, In-process of quality control, working standard, and check sheet. From the monitoring and evaluation after implementation, the result is that the improvement of defects has been reduced from 25,077 pieces to 22,943 pieces, or to 8.51 percent. In aspect of Risk number, the percentage of Risk Number from 4 processes comparing between before and after implementation has been decreased to 54 percent.

title: Analysis of synchronization offsets effect on uplink MIMO-OFDMA systems

description: Synchronization offsets such as time (TO), carrier frequency (CFO), and sampling clock frequency (SCFO) offsets, destroy user’s signal orthogonality in Multiple-Input Multiple-Output Orthogonal Frequency Division Multiple Access (MIMO-OFDMA) fading channel uplink systems, resulting in an interference-limited system. To cope with these impairments, performance evaluations, which can be derived as degradation in metrics of power loss such as Signal-to-Interference (plus Noise) Ratio (SI(N)R) or as an error rate measurement such as Bit Error Rate/Symbol Error Rate (BER/SER), have been proposed. This research investigates the impact of synchronization offsets on the performance of the uplink MIMO-OFDMA systems over multipath fading channel in terms of instantaneous/average SINR at the DFT output of the receiver based on the contents of the DFT window. In addition, the boundaries of the TO are precisely determined. However, the SINR performance evaluation is carried out for arbitrary Subcarrier Allocation Schemes (SASs), and MIMO systems properties as well as various CP conditions, where there is no prior assumption on the interferences’ statistical properties. A general expression for BER/SER is derived based on the analyzed SINR in presence of synchronization offsets. The results obtained in this work, determine the requirements on the accuracy of offsets estimation algorithms when an acceptable amount of performance degradation is given.
