title: Towards safe handling of sensor data in cooperative systems

description: Cooperative Systems promise increased performance by enriching environmental perception through shared data. Conversely, the entailed openness of the individual system architectures threatens their safety. To allow a run-time safety analysis of cooperative functionalities, the integrated components need to share additional meta-data about their sensor failure characteristics. Accordingly, safety analysis methods need to be able to integrate those on run-time. In this thesis, the estimation of Region of Safety (RoS) is proposed as an intermediate layer to dynamically translate between run-time safety approaches and sensor failure models. A review of the state of the art in run-time safety assessment methods reveals their incompatibility with complex sensor failure models. Motivated by concepts in stability theory, the approach of Region of Attraction is identified as a possible intermediate layer. It uses Lyapunov functions to guarantee the safety of systems at run-time. To function as an intermediate layer, the concept is adapted to allow modeling different sources of uncertainty. Furthermore, a new algorithm is proposed to facilitate calculating a set of safe states based on stabilizing states. This concept is termed Region of Safety. Evaluating the approach in the scenario of Cooperative Adaptive Cruise Control shows that safe states are successfully separated from unsafe states, even when considering learning-based controllers. Moreover, the exemplary combination of the approach with the safety assessment based on Level of Service and contract-based safety assessment underlines its applicability to cooperative systems and to act as an intermediate layer. Furthermore, the Lyapunov function, the control strategy, and different sensor uncertainty characteristics are investigated using the inverted pendulum scenario. This experiment demonstrates how those aspects influence the resulting Region of Safety and identifies opportunities for improvement in the concept.

title: Localization of generator inspection vehicle by using visual odometry

description: This research presents a method to determine orientation and translation of Generator Inspection Vehicle (GIV). The GIV is developed to be an inspecting assistant for generator inspection staff to examine the internal condition of a power generator. It is inserted into a space between rotor and stator of a power generator, and used for examining the condition inside the power generator. The main purpose of the GIV is to reduce cost and time spent for rotor removal and insertion. The GIV 1st version was attached with encoders to the vehicle wheels for measuring distance, and its accuracy was 72%. The accuracy is not as good as it should be due to slip between the GIV’s wheels and the surface inside the generator. The slip caused the encoders to miscount rotation of GIV’s wheels. Therefore, a computer vision technique, namely Visual Odometry, is applied to reduce the issue. Visual Odometry (VO) is a process to determine position and orientation of a robot in motion. The mentioned method is applied for localizing of the GIV’s position inside a power generator. This study investigates two VO methods. The first method determines the orientation and translation using optical flow extracted from Features from Accelerated Segment Test (FAST). The second method uses an adaptation of Parallel Tracking and Mapping (PTAM) method to extract the feature points. The GIV’s extracted translation of both methods are plotted to see the trend of motion. The results are evaluated by comparing with ground-truth acquired from a motion tracker system.

title: Formation control of cooperative transport robots using virtual structures

description: This research work reports the formation control method of omnidirectional robots in cooperative transportation. The proposed method was designed based on the concept of virtual spring-damper and virtual leader (VL) – follower methods. The resultant forces from the virtual spring-damper allow a group of robots to maintain the formation while following the VL. The force equations of linear spring-damper and torsional spring are analyzed and applied on the Robot Operating System (ROS) platform to control omnidirectional robots. Besides, the algorithm required predefined data relating formation shape and size. The proposed method has been evaluated both numerically and experimentally. Firstly, the simulation results of Mecanum wheel robots revealed that four follower robots were able to aggregate in a diamond formation and follow the VL in different trajectories while carrying an object. Secondly, the experimental results of two Mecanum wheel robots showed that the robots managed to aggregate in a linear formation. Both robots could follow the VL and deliver an object with the pre-defined trajectory successfully. Clearly, the results confirm the feasibility of the proposed algorithm for cooperative transportation.

title: Improvement on design of cold-formed steel box beams made of built-up C-sections

description: Nowadays, cold-formed steel (CFS) structures are getting popular. CFS beams have recently been used for constructing various types of buildings, ranging from residential housing, commercial warehousing, and industrial buildings. In particular, C-sections and Z-sections are the most popular ones used for such buildings. CFS beam can be used as floor joists and bearers, wall studs, roof panels, and rafters. However, a single section beam has limited capacity, so it might be insufficient for constructing larger buildings that require high structural bending capacity. One common technique to improve the capacity is to assemble two face-to-face single C-sections.The combination to create built-up beams from a single C-section is getting popular in the cold-formed steel (CFS) construction due to its advantage in strength. The investigation of both the experimentally and the numerically mechanical behaviour of the CFS built-up C-section box beam is the main objective of this research. The built-up box beams were assembled of two face-to-face C-section at both the top and bottom of the flanges using batten plates and self-drilling screws. Four connection spacings are considered for each of the nine C-sections, and thus 36 built-up box beams are tested under four-point bending. From experimental results, the connection spacing influenced on the mechanical behaviour of the built-up box beam considerably. The finite element analysis using ABAQUS is conducted and compared with the experimental results. Finite element models demonstrated their ability to accurately predict the behaviour of the CFS built-up C-section box beam with different connection spacings. The flexural strengths of the box beams are also assessed their conformity through the comparison with the predicted strengths relied on the direct strength method (DSM). The analysis indicated that the current DSM equations are entirely usable for evaluating the strength of the box beam in this study.

title: Synchronization control for microgrid seamless reconnection

description: In the three-phase distribution network, the microgrid is widely used for increasing reliability and stability of the power grid. The microgrid is a small power grid that can connect to the utility grid via circuit breaker or switch at the point of common coupling (PCC). On standalone mode, the microgrid will supply power to the local loads by itself, and change to provide or consume power from the utility grid on grid-connected mode. However, during transfer from standalone to grid-connected mode, if the microgrid is reconnected without synchronization, the out-of-phase reclosing might occur. It is a major cause that can affect the power system due to large inrush current or overvoltage during transition mode. Thus, in order to dispose of this problem, the frequency, phase, and amplitude voltage between two grids need to synchronize before reconnection.In this paper, a synchronization control has been proposed for microgrid seamless reconnection. The additional Distributed Generator (DG) is installed at PCC and assigned to be Dispatch Unit (DU). DU is controlled by Droop Control for generating the electric power to adjust the frequency, phase, and amplitude voltage of the microgrid at PCC during the synchronization process in order to reconnect to the utility grid. The proposed method is performed by eliminating the difference of frequency, phase, and amplitude voltage during transition modes. The simulation has been performed in Matlab/Simulink.

title: Treatment of highly colored wastewater from commercial biogas reactor discharge

description: Wastewater effluent from commercial biogas generation is highly colored and poses a serious problem. There is a new standard for control of color from industrial effluent. The new legislation specifies the color value of the discharge from the factory not to exceed 300 ADMI (American Dye Manufacturers Institute method) (Industry, 2017). An effective treatment that can support color removal from wastewater is needed. This work employs a Fenton oxidation process to treat color wastewater from commercial biogas that uses vinasse as its ingredients. The effects of FeSO4 concentrations, H2O2 concentrations and pH on the color removal of biogas wastewater were investigated and optimized using a Box-Behnken design (BBD) under a Response Surface Methodology (RSM). Application of a strongly basic anion exchange resins is conducted to increase the color removal efficiency of the Fenton treated effluent. The optimized condition for color removal using Fenton process is pH 5.5, H2O2 9.8 M, FeSO4 22.3 mM and a reaction time of 24 h. This can achieve a color removal efficiency of up to 98.3±0.1% from the average initial color wastewater of 203,600±3,920 ADMI to 3,540±95 ADMI. This condition achieves a COD removal efficiency of 71.8±0.1% from the average initial COD of 68,000±148 mg/L to the final value of 17,500±68 mg/L.Finally, the accomplishment of color removal to be within the new standard for the color of industrial effluent was achieved using 8% (w/v) anion exchange on the wastewater after the Fenton process. The color removal efficiency of this anion exchange process at 1 hour is 92.4±0.3% with a final COD removal efficiency of 31.3±0.3%. The combined color and COD removal efficiencies of the two process then become 99.9% and 82.3% respectively. The final color value of the treated effluent is 272±11 ADMI whereas the final COD value of the treated effluent is 12,000±44 mg/L.Preliminary microbial fuel cell (MFC) was also applied to reduce COD. The average COD removal efficiency for 270 days is 15.4±2.2% from the average initial COD concentration of 5,640±308 mg/L. It indicates that MFC is not appropriate to treat this type of wastewater neither COD nor color was sufficiently removed. Fenton process followed by anion exchange is recommended as a means for color removal from biogas wastewater treatment. Further treatment is needed to treat COD to meet the industrial effluent standard. This study can lead to new guidance to effectively remove color industrial wastewater for environmental conservation.

title: Biorefinery: separation of value-added components from palm kernel cake

description: The study investigates the fractionation of palm kernel cake (PKC) by sequential extraction, which includes extraction of oil, protein, hemicellulose and lignin.In the oil extraction process, 3 solvents (hexane, acetone and isopropanol) were evaluated. Biomass was extracted for 6 h in a Soxhlet extractor. The efficiency of oil removal by acetone, isopropanol and hexane was 89.93, 89.98 and 90.03 (%w/w), respectively. Moreover, the result from GC-MS found that the majority of fatty acids in the isolated oil was dodecanoic acid (C12:0, Lauric acid) followed by tetradecanoic acid (C14:0, Myristic acid) and oleic Acid (C18:1).Protein extraction from the defatted PKC was studied under 4 variables using different chemical reagents (NaOH, Ca(OH)2, NaCl, Na2SO4 and HCl), concentrations in the range of 0.01-0.3 M, time of 0.5-4 h and temperature of 25-120°C. The maximum extractable protein (%g/g protein) of each solution was obtained with 0.25M NaOH, 0.1M Ca(OH)2, 0.01M NaCl, 0.01M (Na)2SO4 and at 0.1M HCl, which had extractable protein yield as 35.06%, 15.99%, 12.40%, 13.22% and 4.34% (%g/g protein), respectively. The optimal time for protein extraction was 2 h. Finally, the defatted PKC was treated with 0.25M NaOH at different temperature, 25, 35, 50, 80, 100 and 120°C for 2 h. The extractable protein yield achieved as 26.6, 30.9, 53.7, 62.2, 51.5, and 51.9 (%g/g protein), respectively. Therefore, the best condition for extracting protein from defatted PKC was with 0.25M NaOH at 80°C for 2 h, which yielded protein having the sufficient of essential amino acids for adult’s need.Liquid hot water treatment process (LHW), the biomass was studied in water at high pressure nitrogen of 20 bars and temperature of 170, 180, 190, 200, 210 and 220°C. The data showed that extracting at 190°C had the highest efficiency to remove hemicellulose in biomass to 34.19% (g/g hemicellulose), and had the highest yield of hemicellulose in water up to 31.23% (g/g hemicellulose).Soda process was used for removing lignin, which was studied under 2 conditions. There were extractions at 80°C for 6 h and at 120°C for 2 h. The better condition was 120°C because 1.19% of the lignin (%g/g lignin) remained in solid pulp, with was lower than the first condition. With this condition, the yield of cellulose, hemicellulose and lignin that was recovered in liquid phase were 17.17% (g/g cellulose), 2.72% (g/g hemicellulose) and 4.49% (g/g lignin), respectively. In addition, the precipitated lignin from this process had the highest purity when prepared with lignin from other process.

title: Biocomposite scaffolds based on polylactide and chitin/chitosan from fungi extract for tissue engineering applications

description: Biocomposite scaffolds based on polylactide (PLA) and chitin (CT)/chitosan (CS) having different morphologies, e.g., nanofibers and foam beads were prepared by using electrospinning and supercritical CO2 (scCO2) drying techniques, respectively. The study is divided to two parts. In the first part, nanofibers of PLA/CT were prepared by using an electrospinning technique. CT was extracted from different types of fungi, e.g., Xylaria sp. (Xylaria sp. PDW1807002 and Xylaria sp. TGC1807007), and Lentinus squarrosulus (L. squarrosulus RSPG231) by using an acid/base extraction method. The CT obtained from Xylaria sp. PDW1807002, having highest yield, crystallinity, was selected for further producing nanofiber composite. The as-prepared CT and CT treated with alkyl ketene dimer (AKD) or CT/AKD were mixed with PLA solution at various contents, e.g., 1, 2, 5 and 7 wt.% to produce electrospun fiber composites. The properties of electrospinning fiber composites, e.g., chemical compositions and mechanical properties were investigated. The composite fibers with 1 and 2 wt.% of CT/AKD and CT contents showed suitable mechanical strength. In addition, the results from biological tests showed that the composite of PLA/CT has higher cell attachment ability than PLA/CT/AKD and neat PLA electrospun fibers. In the second part, foam scaffolds of PLA/CS were produced by preparing hydrogel before drying with a scCO2 method. PLA/CS hydrogels prepared from various CS: PLA ratios, e.g., 1:0, 7:1, and 3:1 was formed based on a solvent exchange process. After that, the PLA/CS hydrogels were dried with scCO2 at 40°C and 20 MPa to produce bead foams. The variation in the PLA concentrations leaded to differences in pore sizes and porous structures of the bead foams. A 3:1 (CS: PLA) bead foam has highest porosity and specific surface area, but lowest pore size. In contrast, neat CS bead foam has the highest pore size, but lowest porosity and specific surface area.

title: Automatic license plate recognition

description: License plate recognition is an algorithm for extracting components on licenseplate and transforming to an encode text from images. The components on license platecomposes of letters, number, and province name. Though Thai license plate recognitionhas been researched for more than ten years, it still has low accuracy rate in provincepart, From our observation we believed that the main reasons are low quality and resolution of province part , which is about 15-18 pixels of the height.The objective of this research is a framework to extract, and recognize componentson a license plate’s image. A deep learning base object localization called YOLO (Redmon& Farhadi, 2018) is applied to extract components on license plate which are class,number, and province in the recognition part, three machine learning models are constructed to recognize each component. This research focus on low quality and lowresolution images which were taken from the real environment by using fixed orientationof CCTV camera. The proposed framework achieves accuracy rate at 86.45% torecognize whole images.

title: Horseshoe crab genomes reveal the evolution of genes and microRNAs after three rounds of whole genome duplication

description: Whole genome duplication (WGD) has occurred in relatively few sexually reproducing invertebrates. Consequently, the WGD that occurred in the common ancestor of horseshoe crabs ~135 million years ago provides a rare opportunity to decipher the evolutionary consequences of a duplicated invertebrate genome. Here, we present a high-quality genome assembly for the mangrove horseshoe crab <i>Carcinoscorpius rotundicauda </i>(1.7Gb, N50 = 90.2Mb, with 89.8% sequences anchored to 16 pseudomolecules, 2n = 32), and a resequenced genome of the tri-spine horseshoe crab <i>Tachypleus tridentatus </i>(1.7Gb, N50 = 109.7Mb). Analyses of gene families, microRNAs, and synteny show that horseshoe crabs have undergone three rounds (3R) of WGD. Comparison of <i>C. rotundicauda </i>and <i>T. tridentatus </i>genomes from populations from several geographic locations further elucidates the diverse fates of both coding and noncoding genes. Together, the present study represents a cornerstone for improving our understanding of invertebrate WGD events on the evolutionary fates of genes and microRNAs, at both the individual and population level. We also provide improved genomic resources for horseshoe crabs, of applied value for breeding programs and conservation of this fascinating and unusual invertebrate lineage.
