Numerous factors, such as the project's location, land size, price, suitable building shape, and anticipated profits, must be considered, and several building regulations further complicate the design process. Using traditional design methods, such as CAD and Spreadsheets, requires additional resources and leads to the possibility of human error. This study presents the use of parametric design in designing condominiums and comparison with traditional methods by considering the proportion of sales area and profit. Parametric design can generate multiple options based on spatial relationships, calculation algorithms, and design parameters. By adjusting the design's initial parameters, discover potential solutions that meet the predefined objectives developed by Dynamo and Revit, characterized by linking variable data to the building's geometry. A condominium with eight stories was used as a case study. The results demonstrate that the preliminary design's precision, convenience, speed, and scope can be used to make project investment decisions. The conceptual model can also be used as an initial Building Information Modeling (BIM) model to communicate with those involved in the next project development phase. In addition, the proposed parametric model can enhance algorithms to help create solutions automatically as the generate design for future research.</p> 2024-01-22T00:00:00+07:00 Copyright (c) 2024 Journal of Advanced Development in Engineering and Science https://ph03.tci-thaijo.org/index.php/pitjournal/article/view/366 Evaluation of the Potential of Biogas Production from Household Food Waste 2023-09-11T19:21:06+07:00 Boonchai Wichitsathian w_watcharapol@hotmail.com Watcharapol Wonglertarak w_watcharapol@hotmail.com Jareeya Yimrattanabavorn w_watcharapol@hotmail.com Wimonmas Boonyungyuen w_watcharapol@hotmail.com <p>Biogas power generation technology is one of the most viable and environmentally friendly renewable energy sources. This renewable biofuel plays a key role in reducing concerns associated with today's rapidly increasing energy demand and food waste. This research aims to study the optimum conditions for biogas production from household food waste. The Biochemical Methane Potential (BMP) test was used to determine the potential for methane production. It is a study of the effect of F/M ratio equal to 0.125, 0.167, 0.208, 0.250 d<sup>-1</sup>. From the study results, it was found that the F/M ratio equal to 0.25 d<sup>-1</sup> had the highest total solids removal efficiency and COD at 74.71% and 84.38% with biogas generation rate and methane generation rate equal to 15.433 and 6.64 liters per day. To consider the amount of biogas per organic degradation rate, it was found that it was 73.25 L/Kg TS<sub>remove</sub></p> 2024-01-22T00:00:00+07:00 Copyright (c) 2024 Journal of Advanced Development in Engineering and Science https://ph03.tci-thaijo.org/index.php/pitjournal/article/view/589 Histogram Segmentation Technique Using Local Maxima for Image Enhancement 2023-07-11T08:46:07+07:00 Chotmanee Sripuangsuwan chaipichit.cum@rmutr.ac.th jiraporn kiatwuthiamorn chaipichit.cum@rmutr.ac.th Chaipichit Cumpim chaipichit.cum@rmutr.ac.th <p>Different digital images have occurred from digital cameras and different ways of taking images. Therefore, methods to improve the quality of these images have been developed. This paper has presented a method to improve a quality image which is four steps. The first step is to apply the CLAHE method to improve image quality. Next step, take the histogram images of the previous step divided into many sections that are determined by the local maxima method. In the third step, each section is adjusted by the histogram equalization. Finally step, the new histogram is converted to a new gray-level color image. The experiment results of research show that the mean absolute luminance error values of images. These values are compared with values the traditional method. It was found that this method gave better results. Although this method takes more time to process than the traditional method.</p> 2024-01-22T00:00:00+07:00 Copyright (c) 2024 Journal of Advanced Development in Engineering and Science https://ph03.tci-thaijo.org/index.php/pitjournal/article/view/595 Development of Process for Generating Thai Audio Image Description 2023-08-14T20:34:36+07:00 Wasin Pirom wasinpirom@pit.ac.th <p>The motivation for this research began with the requirement to develop a tool for visually impaired and blind people to improve their quality of life by allowing them to access visual information and travel safely. The process for generating Thai audio image descriptions was developed. The research has developed an image detection system that classifies objects in detected images and generates Thai language descriptions without translation from English. The DEtection TRansformer (DETR) is accurately and quickly applied to detect the objects in the image; after that, the Thai sentences or phrases are composed using the Thai Text Generator with the Thai model of WangchanBERTa datasets. The important features of the image description in this research are the ability to indicate the number of objects of the same kind and to select appropriate noun classifiers. In this developed image detection system, objects within the detected image are automatically divided into different images with classification, and then the number of images in each category is counted. The suitable noun classifier is chosen using the Masked Token Prediction. This system can reclassify using zero-shot learning when more different images are added. This allows for more flexibility in use and saves a significant amount of time in creating an image database. The Thai image description consists of the details, including the type of object, number, and Thai noun classifier of objects in the images; the generated sentence to describe the image; and the predicted photo shoot location. After that, the Thai sentences or phases of captured image description are transformed to be the voice in the Thai language using the VAJA Text-to-Speech Engine integrated image detection system to enable visually impaired and blind people to recognize the details of the image in front. The results showed a good performance of the developed process for generating Thai audio image descriptions. The input image file can be transformed into the image descriptions and the Thai audio descriptions.</p> 2024-01-22T00:00:00+07:00 Copyright (c) 2024 Journal of Advanced Development in Engineering and Science https://ph03.tci-thaijo.org/index.php/pitjournal/article/view/599 Corrosion Analysis of Superheat Tube in Bagasse-Fuel Biomass Power Plant 2023-08-03T20:23:07+07:00 Napachat Tareelap napachat.tar@kmutt.ac.th Nawarat Worauaychai napachat.tar@kmutt.ac.th Jirasak Tharajak napachat.tar@kmutt.ac.th <p>This work is aimed at corrosion analysis of STBA12 superheat tube from bagasse-fuel biomass power plant. The results indicated that the fouling on tube surface composed of K<sub>2</sub>SO<sub>4</sub>, KCl and low-melting point eutectics compound such as KCl-K<sub>2</sub>SO<sub>4</sub>. In service the tube surface temperature was in a range of 510-780 <sup>o</sup>C at which eutectics compound melted. This high corrosive molten salt was a reactant for deterioration of steel superheat tube. Cross-sectional investigation found the uniform iron oxide layer which was a product from high temperature oxidation reaction. Additionally localized corrosion attacks, sulfur attack (S-attack) and chlorine attack (Cl-attack), were observed. The S-attack was a superficial and sharp attack about 5-10 mm depth along grain boundaries; whereas, the Cl-attack was a deep attack about 20-50 mm depth along grain boundaries. Source of chlorine was from molten salt and products of sulfation reaction such as chlorine gas (Cl<sub>2</sub>) and hydrochloride (HCl)</p> 2024-01-22T00:00:00+07:00 Copyright (c) 2024 Journal of Advanced Development in Engineering and Science https://ph03.tci-thaijo.org/index.php/pitjournal/article/view/619 Assessment of greenhouse gas emissions from waste management in the shopping center: A case study of the Central Plaza Rattanathibet, Thailand 2023-08-03T20:48:57+07:00 Kanokpish Srinok nuta.s@chula.ac.th Nuta Supakata nuta.s@chula.ac.th Seksan Papong nuta.s@chula.ac.th <p>Human activities contribute significantly to anthropogenic greenhouse gas (GHG) emissions, including waste management in shopping centers.This research aimed to investigate the waste composition and evaluate the GHG emissions associated with waste management in the Central Plaza Rattanathibet, Thailand. The study compared the Busines-as Usual waste management practices (Scenario 1: BAU) with a Zero Waste management approach (Scenario 2: ZW). In scenario 1: BAU, waste management solely relied on landfilling, whereas the ZW scenario in corporated four distinct waste management approaches: landfilling, composting, refuse-derived fuel (RDF 5), and recycling. The findings revealed that the shopping center generated1,967.47 tonnes of waste/ year in 2022. The waste composition was analyzed using the quartering method, and the five most prevalent types of waste were identified as food waste (39.28%), other waste (24.63%), plastic waste (15.52%), paper and board (10.48%), and glass (5.45%). Using the 2006 IPCC Guidelines for Greenhouse Gas National Inventories, BAU Scenario relied solely on landfilling for waste management, resulting in GHG emissions of 999.93 tonne CO<sub>2</sub>eq/tonne of waste. In contrast, the ZW scenario in corporated four distinct waste management approaches: landfilling, composting, refuse-derived fuel (RDF 5), and recycling, which resulted in GHG emissions of -599.54 tonne CO<sub>2</sub>eq/tonne of waste. This negative value indicates that the waste management practices in the ZW scenario resulted in a net reduction of GHG emissions compared to the BAU scenario. This reduction was achieved through the implementation of waste management practices such as RDF 5, composting, and recycling, which directly reduced GHG emissions in the ZW scenario.Additional, encouraging customers and staff to sort waste in the shopping center improves waste management. The GHG emissions data from this study are valuable for policymakers in the Nonthaburi municipality to address climate change and implement mitigation measures.</p> 2024-01-22T00:00:00+07:00 Copyright (c) 2024 Journal of Advanced Development in Engineering and Science https://ph03.tci-thaijo.org/index.php/pitjournal/article/view/721 Environment-Friendly Seedling Pot Made From Palm Oil Sludge and Water Hyacinth 2023-08-01T14:03:00+07:00 Surachai Sangngarm wirot.cha@sru.ac.th Wirot Chaowiset wirot.cha@sru.ac.th <p>This research aims to determine the optimal ratio of palm oil sludge to water hyacinth for producing environmentally friendly seedling pots and to investigate the chemical and physical properties and effectiveness of pots made from the mixture on seedling cultivation. This experiment was arranged in completely randomized design (CRD) with six treatments and five replications based on different mixture ratios of palm oil sludge (POS) and water hyacinth (WH) at the ratio of 5 : 0 (T1), 4 : 1 (T2), 3 : 2 (T3), 2 : 3 (T4), 1 : 4 (T5) and 0 : 5 (T6) respectively. T2, T3, and T4 could be completely molding into pots. POS and WH had pH values of 6.81±0.04 and 6.48±0.17, electrical conductivity (EC) values of 3.36±0.22 and 0.06±0.04 dS/m. Percentage of total N, P<sub>2</sub>O<sub>5 </sub>and K<sub>2</sub>O in POS were 1.84, 3.89 and 2.69 respectively, and in WH were 1.88, 0.28 and 4.10 respectively. T3 showed the highest water absorption capacity (56.52±4.15%) and T2 had the highest inflating capacity (28.79±3.65%). At 2 and 3 weeks after seedling of <em>Brassica rapa</em> L. in pots from treatment 2, 3, and 4 was statistical difference in plant height (P&lt;0.05). T3 resulting in the highest plant height of 3.96±0.49 and 5.12±0.46 cm, respectively. The evaluation results found that all treatment did not deterioration in the physical characteristics of the pots during seedling cultivation. Therefore, this research is an alternative way to use waste materials as an alternative to plastic seedling pots, which have a slow decomposition rate, thus providing an environmentally friendly solution.</p> 2024-01-22T00:00:00+07:00 Copyright (c) 2024 Journal of Advanced Development in Engineering and Science https://ph03.tci-thaijo.org/index.php/pitjournal/article/view/731 Corrosion Kinetics Analysis of Low Alloy Steel Submitted to the Artificial Industrial Environment 2023-08-26T09:43:29+07:00 Chaiyawat Peeratatsuwan thee.c@ku.th Udomporn Tungkasiri thee.c@ku.th Kewalee Petcharatip thee.c@ku.th thee Chowwanonthapunya thee.c@ku.th <p>In this paper, the corrosion kinetics analysis of a low alloy steel submitted to an artificial industrial atmosphere is presented. To obtain the corrosion process model, the corrosion mass gain monitoring was first carried out and the kinetics analysis of the corrosion process using the bi-logarithmic equation was then performed. In addition, Scanning Electron Microscopy (SEM) was employed to investigate the rust morphology change during the corrosion process, and the results from this observation were also used to validate the models constructed by the bi-logarithmic equation. The results of corrosion mass gain monitoring showed that the corrosion process consists of two significant processes: accelerating corrosion process and decelerating corrosion process. The rust morphology observation indicated that the rust of steel was thin and not adherent to the substrate in the initial corrosion process, resulting in an accelerating corrosion process. However, when the rust became thicker and denser in the subsequent corrosion process, the corrosion rate decreased. Obviously, the change in the rust morphology greatly affected the corrosion kinetics. Hence, thefindings corresponded to the results obtained from the corrosion kinetics analysis. Therefore, the mathematics method obtained from the bi-logarithmic equation can be used as a useful approach for the corrosion study in the simulated industrial environment.</p> <p> </p> 2024-01-22T00:00:00+07:00 Copyright (c) 2024 Journal of Advanced Development in Engineering and Science https://ph03.tci-thaijo.org/index.php/pitjournal/article/view/534 Design of a welding table prototype based on Ergonomics with Quality Function Deployment 2023-09-11T21:05:15+07:00 Sawitree Phieboolsilapa sawitree.p@pit.ac.th Pattarawit Srimuang sawitree.p@pit.ac.th Jakkrid Yarangsi sawitree.p@pit.ac.th Ariya Pimpru sawitree.p@pit.ac.th <p>This research aimed to design welding tables with Ergonomics principles using Quality Function Deployment (QFD) techniques.
