title: Applications of statistical process control to advanced radiotherapy techniques

description: The statistical process control (SPC) is the new novel tool in radiotherapy QA process. This research is one of the first studies that applied SPC concept to advanced radiotherapy techniques. For the first research part, the X control chart was performed to establish the reasonable control limits of % gamma pass of nasopharyngeal case in 278 IMRT QA plans and 159 VMAT QA plans, and to assess the efficiency of QA process by using process capability index. The result showed lower control limit of gamma pass of IMRT and VMAT QA of 85% and 90%, respectively. The VMAT QA process was more capable with higher capability index than IMRT. The second part employed the X and EWMA charts for 2 years of weekly output constancy check. The number of point used to calculate control limits was varied from 1 to 5 months of data for all energies, and the λ and L were two more parameters variation. It was found that 2-3 months of data should be employed to calculate control limit of X chart, and 1 month of data should be used to calculate EWMA control limit. At least 20 in-control data point should be achieved to find the process capability and process acceptability with 95% confidence interval. The last part of research work was the setup of local tolerance limits in different data distribution types. Our local tolerance limit for normal distribution data type of percent point dose difference between measurement and calculation of 631 prostate IMRT QA plans was 3.6%. The appropriate lower tolerance limit for left-skewed distribution data type of percent gamma pass of 157 head and neck VMAT QA plans was 88.22%, which was lower than universal action limit. The upper tolerance limit for right-skewed distribution data type of homogeneity index of 150 VMAT PTV plans for head and neck cases was 0.19. The SPC can assist in the QA work in radiotherapy with more efficient than using traditional QA concept.

title: Transit signal priority control using reinforcement learning based on cell transmission model

description: This dissertation is aimed at developing a new framework to control traffic signal light for the road network with recently introduced bus rapid transit (BRT) system. By applying the automated goal-directed learning and decision making called reinforcement learning (RL), the best possible traffic signal actions can be sought upon changes of network states as modelled by the signalised cell transmission model (CTM). There are three main original contributions in this dissertation. Firstly, the model combining CTM to capture the system dynamics together with the implementation of RL approach called Q learning has been introduced for an isolated intersection. Despite of such isolation constraint, a new external delay function has been proposed at the system boundary condition to capture the effects on the neighbourhood of that isolated intersection system. With the proper setting of red light delay as the RL reward function, reported results show that our proposed framework using RL and CTM in the macroscopic level can efficiently find the proper control solution that is close to the brute-forcely searched best periodic signal solution (BPSS). Secondly, the performance comparison of optimal traffic signal controls based on the derivation of theoretical M/M/1 and D/D/1 models and based on the RL approach has been evaluated. In particular, based on M/M/1 and D/D/1 queuing, the optimal split has been derived to minimise the mean waiting time of an intersection with two conflicting flows. The results confirm the validity in adopting the RL approach to control the traffic signal. Finally, an extension to a network of cascading interactions with BRT system has been proposed with simple uni-directional flows without turning movements. Motivated by the BRT system in Bangkok, the conventional signalised CTM has been generalised to cope with the preplanned space-usage priority of BRT over other non-priority vehicles by modelling explicitly the existence of BRT physical lane separator as well as the location of BRT stations. The delay function of both carried passengers on BRT and on other non-priority vehicles as well as waiting passengers at stations has been introduced. Based on the investigated scenarios, the deployment of BRT system with one lane deducted by the lane separator cannot reduce the total passenger delay in comparison with the comparable road and traffic condition before the BRT installation. However, with BRT, the passenger throughput can be greatly increased by up to 9-15\\% in the jamming conditions when at least 40\\% from the overall passengers choose the BRT for their journey. Moreover, our proposed method outperforms the conventional preemptive and differential priority control methods because of the improved awareness of signal switching cost. Based on all findings, the outstanding merit will entirely contribute towards to support the development of sustainable transportation systems.

title: Insar time series analysis for land subsidence monitoring in Bangkok and its vicinity area

description: Since early 1970s, leveling data has revealed land subsidence occurring in Bangkok and surrounding provinces. Though leveling is reliable and accurate, serious drawbacks of the technique are that 1) it measures only places that accessible by roads and 2) it is time-consuming and labor-intensive. Consequently, the density of measuring points is less than one point/km2 which is far too low to capture short wavelength phenomena like land subsidence. This research applies InSAR, a space-based radar technique which can accurately measure distance or change of distance from radar antenna to objects of interest on the ground, to measure land subsidence. A main objective is to apply a combination of two specific methods of InSAR namely Persistent Scatterer (PS) and Small Baseline (SB) to measure occurring subsidence from radar data. PS and SB were employed to analyze 19 images of Radarsat-1, the footprint of which covers most of Bangkok and certain areas of Nothaburi, Pathumthani and Samutprakarn, for the period October 2005 until March 2010. More than 300,000 points, yielding the density of 120 points/km2 are detected as stable which can be treated like survey benchmarks. Thus, the number of points provided by InSAR and its density has largely overcome the under-sampling and bias problem of leveling data. InSAR reveals that Muang, Samutprakarn and Lam luk ka, Pathumthani have been subsiding rapidly at the rate of 20-30 mm/yr. Central Bangkok on the east of Chao Phraya river appears to be subsiding slowly at rates around 10 mm/yr or slower while in northern and western suburban areas are found to subside at rates between 10-20 mm/yr. InSAR also shows fast subsiding areas in Saphansung and Ladkrabang district, Bangkok which have been missed by leveling due to its under sampling problem. At 71 locations where leveling and InSAR data of the same period are available, statistical test (t-test) of subsidence rates obtained from both methods found that 52 of 65 locations where InSAR results available within radius 100 m around leveling benchmarks are identical. Most of the 10 places where InSAR rates are larger are found to be in suburban areas where building density are low. Larger opening between buildings make it more likely for double-bounce of radar echo from building to ground slab to occur and so faster subsiding ground slab contaminated into that of building. The 3 areas where InSAR rates are slower can be explained by phase unwrapping problem. The research result leads to a conclusion that InSAR can be utilized as a geodetic tool to monitor land subsidence but a certain number of leveling points are still required as check points and for certain places where limitations of InSAR may provide unreliable rates.

title: Effects of polysaccharide gel extracted from durian Durio zibethinus fruit-rinds on immune responses in chickens and quantity cholesterol in chicken nuscle

description: Polysaccharide gel (PG) from the fruit-rind of durian (Durio zibethinus Murr.) was studied. This study was to evaluate:(1) the effects of PG as a feed additive diet on body weight gain, fed conversion ratio (FCR), immune stimulation, total bacteria and Salmonella in feces and cholesterol levels in broilers. Eighty broiler chicks at one day of age were divided into 4 groups. Three experimental groups were fed a commercial diet coated with PG at 1, 2 and 3 g/100 g, respectively, and the control group was fed a commercial diet without PG. The study was performed for 42 days. Chicken weight gain and FCR in the treatment and control groups were not significantly different. The hemagglutination-inhibition (HI) antibody titers against Newcastle disease (ND) virus and ELISA antibody titers against the infectious bursal disease (IBD) virus were significantly different (P&lt;0.05). The chickens fed the commercial feed added with 3 g/100 g PG revealed the highest titers against the ND and IBD antibodies than the other groups. There was no significant difference of heterophil:lymphocyte ratio between the treatment groups fed with PG and the control group fed without PG. Total bacteria counts in chicken feces were reduced and exhibited 81-97 % reduction in the experimental groups after feeding PG additive diet for 6 weeks. The Salmonella detected colonies were not found at week 6. Cholesterol levels in the plasma of chickens in the treatment and control groups were not significantly different. However, the cholesterol contents in the muscles of the broilers fed with 3% PG were significantly lower than the chickens fed without PG (P&lt;0.05). (2) the effects of PG as a vaccine adjuvant. One hundred and sixty eight broilers were divided into 3 experimental groups. Three experimental groups were vaccinated with inactivated NDV vaccine containing PG at 0.5, 1.0 and 1.5 g/100 g vaccine; The study was performed for 55 days. The FCR in the negative control, positive control groups, the group received inactivated vaccine with 0%, 1.0% and 1.5% PG and the group were received commercial inactivated ND vaccine were not significant difference. The HI titers against ND virus showed at week 4 that HI titer in negative control, positive control and treated group injected with inactivated vaccine with 0, 0.5, 1.0 and 1.5% PG as well as commercial inactivated ND vaccine were not significant difference (P&lt;0.05). At week 5, the HI titer values in negative and positive control group and treated group injected with 0.5 and 1% PG were not significant difference but significantly lower than those of group injected with 1.5% PG and commercial vaccine. The study found that the PG in diet benefited health promotion of broilers chickens in reduction fecal bacteria, immunostimulation and cholesterol reduction. PG can be used as a vaccine adjuvant to improve the immune system in chicken.

title: Movpe growth and characterization of dilute III-(III)-V-nitride semiconductor : ingapn on gaas

description: In the dissertation, the characteristics of InGaPN/GaAs related to the using as the absorber layer in solar cell were analyzed. In order to verify the band alignment, the InGaPN/GaAs and GaAs/InGaPN quantum wells (QWs) with high structural quality were grown on (001) GaAs substrates by metalorganic vapor phase epitaxy (MOVPE). The results from 10K photoluminescence (PL) of QWs show the extra peaks in infrared energy range. The extra peak of GaAs/InGaPN QW survives for the temperature up to 240K while The extra peak of the InGaPN/GaAs QW is quenched at the temperature about 120K. This situation suggested that both QWs are the type-II quantum structures. The valence and conduction band offsets are approximated to be 450 and 160 meV, respectively. In order to investigate the energy gap of InGaPN and its variation with temperature, the InGaPN layers with various N concentrations were coherently grown on (001) GaAs substrate. With increasing N, the results of PL and photoreflectance (PR) show that the energy gap is decreased. The temperature dependent PL together with fitting show that the temperature dependence of the bandgap energies of InGaPN layers becomes significantly weak with increasing N content. The fitting parameters show the values shift toward the III-nitride (i.e. GaN and InN) characteristic with increasing N. the Raman scattering results in the range of 400 – 900 cm-1 show the GaN-like characteristic. This suggests that the Ga-N bonds make a larger contribution than In-N bonds in InGaPN samples. The less dependence of bandgap on temperature property might be mostly contributed by Ga-N bonds.

title: Secondary metabolites produced by Streptomyces parvulus Strain J6.2

description: Streptomyces parvulus J6.2 was isolated from soil in a mangrove area and studied its metabolites. The morphology and 16S rDNA sequences were used to identify it as belonging to S. parvulus. Comparison of 16S rDNA sequences showed that S. parvulus J6.2 had a close relationship to the actinomycin-D producing Streptomyces species. Carbon utilization indicated that S. parvulus J6.2 was a novel strain. Actinomycin-D, a major bioactive component, was isolated from ethyl acetate crude extracts by reverse phase HPLC using isocratic of 30% methanol in water as the mobile phase with a 3 ml min-1 flow rate. The molecular structure of actinomycin-D was confirmed by 2D-NMR. Medium optimization gave the highest yield of 378.84 mg/l actinomycin-D when grown in a sodium caseinate broth supplemented with 20 g/l malt extract as the culture medium. Starch and malt extract supplemented culture medium produced high crude metabolite yield therefore increasing actinomycin-D production. High concentration of NaCl in culture medium suppressed production of triglyceride metabolites resulting in more specific production of actinomycin-D.

title: Biological activity investigation of Colocasia gigantea extracted fractions

description: In order to supply new information on the biological activity of Colocasia gigantea (Araceae) extract, This study investigates the optimal solvent system for phenolic compounds extraction, antimicrobial activity and cytotoxicity of C. gigantea’s extract. The methanol-water binary solvents of varying methanol fractions were used for phenolic compounds extraction. The optimal extraction of the solvent can be described by the solvent polarity represented by the solubility parameter. The optimal condition for the solvent to extract total phenolic compounds from C. gigantea was predicted at solubility parameter 33.6 and 42.5 MPa⁰⋅⁵ in the tuber part and leaf respectively. The antimicrobial activity of C. gigantea was determined by disc diffusion method. All extracts from leaf of C. gigantea were found to be more effective than extracts from tuber against Escherichia coli ATCC 25922, Bacillus subtilis ATCC 6633 and Staphylococcus aureus ATCC 25923. In the study of cytotoxicity, we investigated cytotoxicity of C. gigantea extract on cervical cancer (Hela), melanoma (A375) and human white blood cell (WBC) in vitro. The experimental results showed that not at all part of C. gigantea had cytotoxicity on Hela and A375 cells whereas some of C. gigantea extract from leaf (especially used dichloromethane as a solvent) could promote Hela and A375 cells proliferation significantly. Additionally, only the extract (used n-hexane as a solvent) from the tuber had cytotoxicity on Hela and A375 cells and also enhanced WBC cells proliferation.

title: Search space reduction technique for molecular docking calculation

description: To dock organic ligands in to protein binding sides by using devide-and-conqure method. The method can be used in the virtual screening process of designing a specific protein ligand. The molecular surface energy representation of protein and ligand can be used to filter out by sorting algorithm along with indexing method. Object oriented paradigm, a powerful tool for data abstraction and encapsulation, can be used for accessing all index in real time. Sorting algorithm by heap sort can guarantee the fastest and time consistency regardless of the variation of input data. Combining all of these can make sure that all possible data can be search in the complete and optimum way. Computer graphic calculation is a really good in parallel computing. Introducing computer graphic calculation can guarantee parallelizable in the most effective way. This paper will introduce the new method by using energy based virtual screening to do the complete search of autodock grid map energy. The result of program is a position and orientation of ligand in enzyme. However, there are some missing angle and interpolation area between the grid map corners. This problem can be solved by doing recursive search in the near area of the first output data.

title: Ultra-Fine electrospun nanocomposite fibers of polymer-conductive polymer-nanoparticle

description: In this research, ultra-fine fibers of polymer – conductive polymer blend, polymer – nanoparticle and polymer – conductive polymer – nanoparticle nanocomposite are fabricated, characterized, and investigated. Poly(3,4-ethylenedioxythiophene)/ poly(styrenesulfonate) blended with silver nanoparticles and correlated morphology are studied in details including the shapes and sizes of ultra-fine fibers. Electrospinning processes are considered as ultra-fine nanocomposite fibers of polymer-conductive polymer-nanoparticle formation. (This specific technique requires a syringe with a needle, a high voltage unit, and an aluminum foil (screen) as a collector.) The fabrication conditions for the electrospinning processes in the synthesis of ultra-fine nanocomposite fibers in this study are initially summarized whereby voltages between 12.5-22.5 kV are applied on a collecting distance of 15 cm in 5 minutes for random fiber formation and 20, 30, and 45 minutes of both aligned single fiber and aligned fiber mat formation which are generated from PVA blended with various PEDOT/PSS and AgNPs concentrations. The fiber diameters resulting from these permutations by the researcher in this review varied from 0.1 µm to 0.33 µm. This research illustrates the ultra-fine electrospun nanocomposite fibers of polymer-conductive polymer-nanoparticle which conduct higher electrical conductivity when loading higher PEDOT/PSS, and AgNPs concentrations to form ultra-fine fibers. The range of conductivity is varied from 4.23 to 92.18 S/cm, under the aligned single fibers technique, and from 1.94 to 13.57 S/cm, under the aligned fiber mat technique.
