Item Open Access Application of finite element analysis in design to reduce production costs(Mahidol University, 2023) Somkitti Naksanpaya; Eakkachai Warinsiriruk; Noppakorn PhurayaThe objective of this research is to apply finite element analysis to analyze the strength of Balancing Support which has been improved to reduce production costs. In designing, the two aspects to consider are strength and cost. The part..., so the big workpiece has a higher cost than the small workpiece. Therefore, strength directly affects cost. In this research, the balancing support, which is the device of the overhead crane, has been redesigned. Each part is designed to reducePublication Metadata only REACT: An agile control plane for industrial wireless sensor-actuator networks(2020-04-01) Dolvara Gunatilaka; Chenyang Lu; Mahidol University; Washington University in St. Louis. This paper presents REACT, a reliable, efficient, and adaptive control plane for industrial WSANs. Specifically optimized for network adaptation, REACT significantly reduces the latency and energy cost of network reconfiguration, thereby improving the agility...© 2020 IEEE. Industrial automation is embracing wireless sensor-actuator networks (WSANs) as the communication technology for industrial Internet of Things. Due to the strict real-time and reliability constraints imposed by industrial applicationsItem Metadata only Towards sustainable sugar industry in Thailand: Cost and benefit analysis(2025-01-01) Junkraweekoon R.; Kwonpongsagoon S.; Kingphadung K.; Junkraweekoon R.; Mahidol Universitycrystal, with 77% coming from sugarcane production and 23% from the sugar production process. The highest cost of sugarcane production was in the weed control process, accounting for 38%, followed by fertilizer application, planting, sugarcane transported...This study analyzes the financial costs and benefits associated with various agricultural practices, industrial processes, products, byproducts and waste management, starting from sugarcane plantations to the end users of products and byproductsItem Open Access Modelling logistics cost in hospital : a case of medical products(Mahidol University, 2021) Khem, Chanrong, 1995-; Duangpun Singkarin; Jirapan Liangrokapart; Tuangyot SupeekitHealthcare providers presently operate in a situation of multifaceted supply chains. Due to lack of attention, real costs has increased and made implementing a costing system difficult. The fundamental issues for healthcare management today should... have been taken into consideration. Based on this matter, the study focuses on logistics activity and cost analysis of such activities from warehouse to ward of the case study hospital. The aim of this study was primarily directed to analyse activityItem Metadata only Wireless control system design for 5-AXIS educational robot arm(Mahidol University. Mahidol University Library and Knowledge Center, 2024) Ananchai Choowongwut; Kiattisak Sritrakulchai; Supphachan Rajsiri; Mongkol Thianwiboonan open-source application to the alternatively less complicated and low-cost controller. This allows the connection between an assigned user and the robot arm for student training and laboratory practices. As a result, a system using Bluetooth...This research work was initiated according to the demand to replace the malfunction controlling system with commercially licensed software of a 5-axis robot arm with an IR50P model. A new controlling system was conceptually designed by integratingItem Metadata only Sustainable development model of value engineering(2006) Supphachai Nathaphan; ศุภชัย นาทะพันธ์; Pattamon Jintanapong; พัทธมน จินตนาพงษ์; Sarayut Nathaphan; สรายุทธ นาทะพันธ์; Mahidol University. International College. Business Administration Division.Energy cost is accounted for the largest portion of production cost in any industry. Energy cost saving can be done via using energy efficiently. Motivation of this study is to develop mechanism in using energy efficiently called “Sustainable... of value engineering are i) Planning ii) Controlling and iii) Improvement process, which lead to sustainable value in engineering application. By gathering facts and information among working members, actual problem and jurisdiction of each partyPublication Metadata only Low-Cost Educational Feedback Control System: Helicopter Tail Rotor for Yaw Control(2020-04-01) Ittichote Chuckpaiwong; Arom Boekfah; Mahidol University© 2020 IEEE. This paper presents a low-cost educational mechatronic system - a simplified helicopter tail rotor for yaw control - used in a 12-hour graduate-level module. Details of hardware configuration, modeling, simulation, and experiment... of helicopter tail rotor are provided. Feedback control using proportional-integral-derivative (PID) controller is implemented in real time through MATLAB support package for Arduino hardware together with Arduino Uno microcontroller. Experimental outputItem Open Access Risk assessment in contract signing for intellectual property trading in the entertainment and media industry(Mahidol University, 2021) Weerawit Loetwatthanasakun; Supara Kapasuwan; Alessandro Stasiempirical findings on how risk is perceived by licensors and licensees based on factors derived from transaction cost economics theory (TCE) and relational contract theory (RCT). The survey results indicated that licensors tend to perceive low risk from... transactions if licensees have high role integrity, mutual practice, and joint problem solving, which are factors in RCT, while licensees perceive low risk from transactions if licensors propose low transaction costs, specific governance structureItem Metadata only Development of the human following robot control system using HD webcam(Mahidol University. Mahidol University Library and Knowledge Center, 2018) Jutarat Jommuangbut; Kiattisak Sritrakulchai; Soranat Rhaipu; Supphachan RajsiriRobot has been recently developed for using in interactive environment to support human, for example, industrial application. Since the robot, used in industrial application, exhibits high cost and import from other country, in this research..., the human following robot for tracking human operator was designed and developed by using HD webcam to detect the colour and separate human target from unknown environment.
