While data coming from the satellites or drones provide a bird-eye view, but data coming from the ground through IoT sensors or mobile phones (crowdsourcing) can provide actual status in real-time. This eventually contributes to the “big data” where pertinent data/information are gathered from a large number of sources, and “data analytics” subsequently helps in converting it into significant information for decision making and tackling issues at scale and speed. Machine Learning and Artificial Intelligence (AI) algorithm have made it easy to handle and process the enormous volume of this wide range of data. A few innovative applications of the geospatial data and technologies in disaster management, agricultural crop monitoring, and environment management will be covered. These include applications of geospatial data and technology in (1) Post-disaster disaster response & reconstruction, (2) Multi-hazard Risk Assessment for risk mitigation, (3) Agro-Ecological Zoning for crop suitability assessment, (4) Weather Index Insurance product development, and (5) Plastic litter monitoring at city scale.

I have learnt how to create new value by using academic knowledge and industry knowledge to create new business in Thailand. I ‘d transformed my company and trained my staff to achieve the new goals to develop something new that can be solve social and industry problem. My invention named Pre-Aseptic-Sterilization System plus (PASS+), thin-film design increases the liquids’ exposure to UV-C, enabling greater efficacy and consistency in pre-treatment. The Laminar flow of the liquid over the lamps inside thin film chamber ensures an inactivation and the multiple- lamp system guarantees added food-safety by extending shelf life of the liquids. Our technology delivers trustful, countable UV-C efficiency. PASS+ for improving quality of raw milk from small and medium size dairy farm in Tropical countries. The mechanism of this invention, the microorganism inactivation system uses short wave light to improve the quality of raw milk for small and medium dairy farms. The 254-nanometer wavelength is used to reduce the number of microorganisms in raw milk without affecting the quality. This is a new alternative in controlling the number of microorganisms in raw milk during the transport from farms to milk collection centers. It is the innovation that provides farmers in small and medium dairy farms with access to novel food technology at affordable cost. As a result, these dairy farmers will be able to generate higher income, have better quality of life and preserve their royal granted career, leading to sustainable development of the country. The efficacy of this innovation had been approved by National Institute of metrology (Thailand) under by Ministry of science and technology. They validated our innovation’s efficacy by using the spectroradiometric method using the CAS 140CT-154 Spectrometer to compare with USFDA part 179.39. The resulted was higher than normal standard and declared the scientific evidence that this innovation can “reduce of pathogenic microorganisms in raw milk to add the value for the farmers”. This solution better than using cooling system because PASS+ can reduce and control while cooling system only can offer for control in controlled temperature. The initiate investment PASS+ cheaper 50% than cooling system and offer higher margin to dairy farmers and break even point will be on 2-3 years.

Bonsangue* Leiden Institute of Advanced Computer Science, Leiden University Niels Bohrweg , 2333 CA Leiden, The Netherlands *Corresponding email: [email protected] Abstract Software systems are increasingly pervasive in today world, influencing all activities and processes in which businesses operate. The development of large software systems is a complicated process involving many design and implementation decisions, which if poorly done increases fault proneness and code complexity and reduces software system maintainability. Code smells are properties of software that may indicate the presence of such flaws in its design or some poor implementation choices. Differently from a bug, code smells do not necessarily affect the technical correctness of a program, but rather they may be interpreted as symptoms of the bad quality of a software system. Due to the subjectivity of their definition, detection of code smells, and the associated code refactoring to eliminate them, are non-trivial tasks. The manual detection process requires tremendous efforts and is infeasible for large-scale software. In this talk, we will present how different digital technologies and AI based techniques can help in automatically detecting of code smells to overcome some of the challenges software developers are facing in the design of correct software. The talk is based on joint work with Chitsutha Soomlek (Khon Kaen University) and Jan N. van Rijn (Leiden University). Keywords: Code smells, Machine learning, Software engineering 5

Furthermore most conventional treatment methods require expensive specialist equipment that are costly to run and very energy demanding. The overall objective of this study was to explore the potential of biological treatment of metal working fluids (MWF) wastewaters which was selected as representative of the challenge sustainable treatment of problematic wastewaters. MWF are extensive employed in industry, are difficult to treat biologically since they are formulated specifically to resist biodegradation and contain high concentration of biocides. Despite the inhospitable nature of MWF they are eventaully colonised by microbial communties. Thus the specific objective of this study was to undertake an extensive investigation of the temporal and spataial diversity of MWF in samples collected temporally and spatially, globally. This revealed that overall the diversity of MWF bacterial communities was very low, but some common species were ubquitously distributed in geographically separated samples. The subsequent objective was to enrich and isolate bacteria from the characterised MWF bacterial community and assemble consortia that were effective at degrading the chemical constituents of the waste. In total 6 consortia were tested in terms chemical oxygen demand load, used as the measure of treatment effectiveness. The third objective was to scale-up from laboratory flask to 5000 litre bioreactors and test the performance of the best bacterial consortia for treating waste MWF when grown as a biofilm grown on holding matrices. This demonstrated that the fixed biofilm could reduce MWF carbon loads of 80,000 mg/L to around 5000 within 48hrs. Subsequent performance at full commercial scale was found to be equally impressive. In more recent studies application of nano-scale iron oxide and MWF pretreatment with an electronic beam stimulated biotreatment ever further.

In supercapacitors, the energy storage performance is largely determined by the structural and electrochemical properties of electrode materials. Consequently, numerous studies have focused on the developing electrode materials for achieving high-performance supercapacitors. In this work, we report the development of electrode materials consisting of biomass-derived porous carbon materials, nanostructured oxides and composites, and glass-based ceramic materials. The nanostructured materials and composites are prepared through various synthetic methods including sol-gel, hydrothermal, electrospinning, and so on. The physical characteristics of the materials are deliberated and discussed in detail using basic and synchrotron- based characterization techniques. The electrochemical performances of the materials are evaluated in aqueous-based electrolytes via electrochemical techniques consisting of cyclic voltammetry (CV), galvanostatic charge/discharge (GCD), and electrochemical impedance spectroscopy (EIS).

It is still significant subject to study and crucial target for many polymer chemists in 21st century. The reason why the synthetic rubbers are distinguished from natural rubber may be explained to be due in part to a lack of information of structure of natural rubber since many approaches have been made to prepare the synthetic rubbers, so far. It is, therefore, quite important to analyze the structure of natural rubber from a different perspective. The study on the structure of natural rubber began with a determination of chemical composition. Faraday1) determined a ratio of carbon to hydrogen of natural rubber, i.e., 7.5, in 1826. From the result, C5H8 was proposed as a chemical composition of natural rubber. In 1860, Williams2) isolated isoprene from natural rubber by destructive distillation of the rubber. In 1884, Tilden3) proposed a correct structural formula of isoprene as CH2=C(CH3)-CH=CH2. Staudinger4) discovered that natural rubber was a macromolecule consisting of isoprene units, in 1920. In 1925, Katz5) reported cis-1,4 configuration of isoprene units for natural rubber, based on analysis of crystalline form through X-ray diffraction technique. In 1994, Tanaka6),7) found the existence of two trans-1,4- isoprene units at -terminal side and linked fatty acids at -terminal side. Based on the history of the structural analysis, it is evident that the study on structure of natural rubber in 19th century and 20th century focused only on a primary structure of the rubber. We discovered that natural rubber is a naturally occurring nanocomposite8), which consists of cis-1,4-polyisoprene as a major component and non-rubber components such as proteins and lipids as a minor component. The cis-1,4-polyisoprene is prepared from isopentenyl diphosphate by biosynthesis of plants, and the proteins and lipids contribute to the biosynthesis as enzyme and biological membrane, respectively. The biosynthesis is homogeneous in the initial stage since monomers and substrates are hydrophilic. However, the reaction undergoes homogeneous to heterogeneous during biosynthesis due to chain extension of natural rubber since cis-1,4-polyisoprene is hydrophobic. Thus, phase separation takes place during biosynthesis of cis-1,4-polyisoprene to form an oil in water emulsion, i.e., latex. The proteins and lipids exist on the surface of the natural rubber particles to stabilize the latex since they are amphipathic. The nanophase separated structure is, thus, inevitably formed in natural rubber when bulk natural rubber is prepared from the latex. It consists of the natural rubber particles with a diameter of about 1 m and matrix of the non-rubber components with a thickness of several ten-nanometer. We, thus, named this nanophase separated structure “nanomatrix structure” in 20118) since the thickness of the matrix was several ten- nanometer. In this presentation, we report the discovery of nanomatrix structure of natural rubber and structural design of its mimetic composites. Discovery of the Nanomatrix Structure Figure 1 shows TEM images for natural rubber and deproteinized natural rubber (DPNR), in which bright domains represent natural rubber and dark domains represent the proteins.

This nano phase separated structure was similar to the nanomatrix structure proposed in our previous study9),10). By contrast, for DPNR, no nanophase separated structure was observed in TEM image11). In other words, the nanophase separated structure of natural rubber disappeared after removal of proteins from the rubber12). Figure 1 shows TEM images for natural rubber and deproteinized natural rubber (DPNR), in which bright domains represent natural rubber and dark domains represent the proteins.

To prove the nanophase separated was about 10 times higher than that of HANR. structure of natural rubber, we centrifuged This demonstrates that natural rubber with a natural rubber latex to prepare DPNR and serum large amount of the proteins (high protein natural rubbers13).

Fewer voids were observed in SEM images of the cross sections, indicating that we could suppress formation of the voids by fixation of the proteins with glutaraldehyde before staining the rubber with OsO4. Furthermore, we investigated the effect of temperature in staining process on the morphology to determine the suitable staining condition. The effect of the temperature of OsO4 on morphology is shown Figure 2 (a) and (b). It was found that staining with OsO4 at 35 °C is more effective than 5 °C. 198

Therefore, the suitable staining condition, where no voids were observed, was found to be at 20 °C for glutaraldehyde and 35 °C for OsO4. Figure 2 shows SEM images of the etched surface of the serum rubber stained with 25 % glutaraldehyde aqueous solution for 12 h followed by 4 % OsO4 aqueous solution for 48 h. Temperature for each process is as follows: (a) glutaraldehyde at 35 °C and OsO4 at 5 °C, (b) glutaraldehyde at 35 °C and OsO4 at 35 °C and (c) glutaraldehyde at 20 °C and OsO4 at 35 °C. After we stained the serum rubber under the suitable condition, we performed three- dimensional observation by repeating etching with FIB and Figure 3 3D SEM image for the serum rubber observing with FE-SEM alternately. Figure 3 shows three-dimensional reconstruction image of the serum rubber. The box size in the image is about X = 6 m, Y = 4 m, Z = 7 m. Since non-rubber components are stained with OsO4, bright domain represents non-rubber components and dark domain represents rubber particles. Because of no voids, we successfully reconstructed three- dimensional image of the nanomatrix structure for the serum rubber. It is found that natural rubber particles of about 200 nm in diameter are dispersed in the matrix of non-rubber components with a thickness of several ten-nanometer. Preparation of Novel Synthetic Rubber Figure 4 TEM image of the The nanomatrix structure is formed by covering nanomatrix structure formed with isoprene rubber and polystyrene. rubber particles with nanoparticles followed by coagulation of the resulting nanoparticles-covered rubber particles. In Figure 5 Stress-Strain curves. this case, the rubber particles are required to chemically like a:PI-graft-PS90, b:PI, c: natural rubber to the nanoparticles to stabilize the nanomatrix structure in equilibrium state. Especially, for synthetic rubbers, the chemical linkages may be formed by graft-copolymerization of a monomer onto the rubber particles in latex stage, since the rubber particles in the latex are dispersed in water. Therefore, in the present study, the graft- copolymerization of styrene onto synthetic cis-1,4- polyisoprene (PI) particles was performed in latex stage14). Figure 4 shows the TEM image (5000x) of PI-graft- PS. The dark domains represent the PI particles and the bright domains represent polystyrene (PS) nanoparticles. The TEM image for PI-graft-PS, the PI particles with an average diameter of 1 m as a dispersoid were well dispersed in the nanomatrix of polystyrene with a thickness of several ten-nanometer. It is, thus, found that the nanomatrix structure is formed by graft-copolymerization of styrene onto the PI particles in latex stage. Figure 5 shows stress-strain curves for PI-graft-PS, PI and natural rubber in the unvulcanized state. The stress- strain curve for PI-graft-PS was almost identical to that of natural rubber, whereas it was distinguished from the stress- 2109

The main objective of this research is to study the feasibility of a small solar power ice production system in areas not accessible by power grids line. To improve the reliability of the aforesaid system, the biomass energy then be proposed as an auxiliary energy source. The criteria for system design is assigned for a 30 kg/day vapor-pressure ice making machine which will be operated for 12 hours a day using electricity from a 5 kW solar panel. The simulation results show that the proposed ice production system needs more external power during the months of September and October, requiring up to 3 . 1 0 6 and 3 . 0 3 5 Kw/day, or 6 4 % and 6 3 % of the full day's load, respectively. In addition, the minimum energy demand in a load day month of 1.768 GWA or equal to 36.8%. The most needed additional energy is 06.00-08.00, which requires a lot of energy to reach 87% of the load.

Due to changing customer needs and increasing the degree of global sustainability, many organizations try to adjust their supplier selection and evaluation criteria in order to choose the most suitable supplier for their business. For this reason, this paper aims to analyze and comparative study on criteria used for supplier selection and evaluation emphasized on sustainability perspective. Moreover, a comparative study on supplier selection and evaluation criteria among selected industries is also presented. The study initially relies on literature reviews ranging from 2015-2020 which mostly focused on the terms of sustainable supplier selection and sustainability manufacturing in order to identify the criteria used for supplier selection and evaluation. Then Pareto principle is used to analyze in order to identify the most popular criteria used for selecting the sustainable supplier. Three industry sections; automotive, electrical appliance & electronic and fashion & textile are selected for a comparative study in order to investigate the similarity or difference among criteria used for sustainable supplier selection and evaluation. The results show that the criteria used for sustainable supplier selection and evaluation can be classified into three main dimensions; economic, environmental and social perspectives. By a comparative study among industries, it found that there have similarities on three main criteria used for sustainable supplier selection and evaluation. The results of this study will be beneficial for any industry to use them as a guideline to adjust its supplier selection and evaluation strategy in order to fit the organization's strategy sustainably.

The signal frequency was 21-30 KHz with a maximum power of 4.97 watt, where 4-tweeter speakers were used to propagate the mechanic wave into the air. The power supply can be either switched by 220 VAC/50 Hz or 12 VDC/18 A. The frequency propagation mode was designed as auto on/off; mode 1: 60s- on/10s-off, mode 2: 120s-on/20s-off, and mode 3: 180s-on/30s-off. In our experiment, effective range (indoor) was 1.2 m at 22-26 KHz.

The electricity from fossil generate Co2 and P.M.2.5 dust to the air, therefore the water treatment made more pollution to the air for the traditional system. This research shows the new concepts of water treatment by net zero CO2 using wind turbines and solar PV to generate the compressed air to water treatment pond. The system compound with 5kw air compress wind turbines with 3kw PV for generates electricity to air compressor. Both wind and PV produce the air to the water treatment pond. The fossil fuels, which is causing global warming and making the air and soil polluted therefore will not occurred in this design. From the analysis of wind speed at the CPF aeration pond, Kaeng Khoi, Saraburi province, from the research team showed the appropriated design that will install a 5 kw and 3kw PV in hybrid system. These can be displayed as shown in the result of the average wind speed, which is processed by the wind speed model analysis program. This system show the average wind speed in the area at the location of the CPF aeration pond. The analysis of the area obtained from the CPF Kaeng Khoi aeration pond survey revealed that the annual average wind speed was about 3.17 m/s at an altitude of 10 m from the ground and at a wind speed of 4.8 m/s at the altitude of 50 meters. However, the investigation result shown the average wind speed about 4.5m/s could be used to simulate the airflow form the wind machine about 600 litters of compressed air per minute, which is processed by the wind speed model analysis program compared to the wind machine specification. Additionally, for the solar radiation power density was simulated using the PVsyst software to analyst the direct normal irradiation to the focused area. The power density results shows 1,284 kwh/m2 to estimate the air flow from the PV system per year. It was found that the power generation capacity of the system was approximately 4,482 electrical units per year. This will result in the use of clean energy for the environment. The hybrid wind solar system if applied to the site will replace electric bill to the investor or customers about 350,000 baht per year.

This unit was operated for safety and operational reasons. However, without proper controls, doing so could result in energy losses and higher production costs as well as environmental impacts. Therefore, a systematic study and guideline for flare gas reduction technology are of paramount importance. This research aims to 1) evaluate the technology to reduce greenhouse gas emissions from gas flaring 2) assess the emission factor of gas flaring in the Thai petrochemical industry 3) assess the other environmental impacts such as acidification, photochemical effect, and health impacts, and 4) propose the recommendations and limitations for reducing GHG emission from gas flaring of Thai petrochemical industry. Life cycle assessment (LCA) was used as a tool to assess the environmental impact of the gas flaring. The goal is to identify the environmental impacts of gas flaring and propose options to reduce its impacts. The scope of this study was gate-to-gate. IMPACT 2002+ was applied for calculating environmental impact assessment. The results showed that the greenhouse gas emission factor of gas flaring from the petrochemical plants in this case study were in the range of 2.26E-05 – 2.12E-01 ton CO2eq /scf and the average value was 3.03E-02 ton CO2eq/scf. In addition, the result of the environmental impact assessment identified that the factory case study can emit the highest impact of respiratory inorganics, terrestrial acid/nutria, and aquatic acidification for 11,0870 kg PM2.5eq, 4,780 kg SO2eq, and 609,721 kg SO2eq per year, respectively.

With the long period of experiences that not only closely accompany by working with the 1st. and 2nd.year students but the development of teaching material should be continuously improved. Normally the 1st. year students take the basic (general) engineering drawing, and the 2nd. year students use computer program to the draw the metal work, machined parts also 3D-drawing included assembly drawings as well as explosion drawings. There are more than 2,000 investors from many countries, which work on engineering drawing in respect to the International Standard Organization-American (ISO-A) and International Standard Organization-Europe (ISO-E). Presently more than 1,763 Japanese companies are registered at the Japanese Chamber of Commerce (JCC, April, 2020) in Bangkok. 39 percent of investment as majority investor in Thailand (not included Thai-Industries and SME) and followed by European Union (EU) 15 %, 8 % from USA (not included Thai-Industries and SME). Therefore both standards ISO-A and ISO-E are widely being used in the most industrial goo sector. In this regard both standards have instantly introduced in teaching course of engineering drawings. The most common error cases in working of assignments on the first 3-5 weeks of former students (from many years ago) must be clearly explained on several cases (examples) to the new students and emphasized them to be aware during doing their assignments, especially to follow rules of in technical drawings of industrial standards, i.e. dimension rules on the work parts. Thus in order to gain best results in which the percentage of good working students would be nearly double increased. Keywords: Engineering drawing, Practical drawing, Technical drawing learning. 320
