A dynamic model of the vehicle is established for simulation. Matlab/Simulink software is used to simulate and calculate the root mean square (RMS) accelerations of the driver’s seat and cab pitch angle under different operation conditions. Proportional-integral-derivate controller with its parameters optimized by the genetic algorithm (GA-PID controller) and Fuzzy logic control combined with PID (FLC-PID controller) are used to control the semi-active cab suspension system of the heavy truck. The obtained results show that the ride comfort of the vehicle using FLC-PID is better improved in comparison with using GA-PID under different operating conditions. Especially, when the vehicle moves at a speed of 72 km/h, the RMS accelerations of the driver's seat and cab pitch angle are greatly reduced by 26.45 % and 26.07 % respectively. Therefore, the FLC-PID control should be applied to the suspension system of the vehicles to improve the vehicle's ride comfort.","PeriodicalId":314911,"journal":{"name":"Journal of Mechatronics and Artificial Intelligence in Engineering","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126542028","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Control of any system is significant, especially in chemical process systems. For this, it is necessary to use a control that can meet the system's demands and work harmoniously. In this study, a system that can be adapted to the chemical process industry has been designed and modelled in the COMSOL program. The concentration level and velocity behaviour of the same type of fluid applied from two channels over this model were kept at the desired level with the Proportional Integral Derivative (PID) control algorithm. The flow rate of the fluids can be changed with the controller to achieve the desired concentration. As a result of the simulation with different PID coefficients, the best response was obtained when the high proportional gain coefficient was applied. It has been determined that the best response of the process in both concentration and velocity data is achieved when kp= –1 m4/(mol·s). A high overshoot and steady-state error occurred at low proportional gain values in the system response.","PeriodicalId":314911,"journal":{"name":"Journal of Mechatronics and Artificial Intelligence in Engineering","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126507933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It aims at targets such as reducing the damage to people and the environment by increasing traffic safety with smart transportation systems. In addition, one of the big problems of long-distance drivers is falling asleep while driving. This is an event that puts both the driver’s life, the passengers in the vehicle, and the vehicles on the road in danger, and puts the company in a difficult situation if it works for a company. In this direction, the driver sleep alarm project has been developed. This project is a control system based on monitoring the user, measuring, and analyzing their movements. Literature research, which is the first stage of the project, was conducted and research continued throughout the project process. Within the scope of this project, a headset was designed for the driver’s sleep alarm and a mobile application was created. The first prototype of the project was built. First, in the project, the angle values made by the driver's head were produced with the IMU connected to the microcontroller. 10° to 20° margins identified as sleeping state for roll, pitch, and yaw angles. Later, a wearable headset was designed for the driver. Based on these angles produced in the microcontroller, an algorithm has been created that detects whether the driver is asleep. These generated angle values and status information were transferred from the headset to the mobile application via Bluetooth. This data transferred in the mobile application is reflected on the screen. In addition, an algorithm has been created in the mobile application, which sends a notification to the driver when sleep status is detected and sends an informative SMS to the headquarters if the driver is unresponsive to this notification. For the second prototype, it was aimed to produce a PCB for the headset and thus make a new mechanical design. Data mining applications are planned with the collected data from drivers for future works.","PeriodicalId":314911,"journal":{"name":"Journal of Mechatronics and Artificial Intelligence in Engineering","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128126345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research breaks the traditional method of reducing CWS at the production end and chooses to find breakthroughs from the whole life cycle of products. Finally, innovatively based on product lean design, and from the product design side, explore the optimization opportunity to reduce the CWS value of product production, so as to achieve the purpose of reducing CWS. Firstly, laptop model S is selected as the research object, and its structure disassembly and analysis, assembly action research and station sequencing were carried out to preliminarily determine the product production process. According to the production bottleneck process time, the current CT of the production line was determined to be 13S, and the initial CWS value of the production line was calculated to be 0.2167. Then, based on the principles of lean product design, the CONN of FAN, Battery, Speaker and RCT are optimized to make their assembly easier. The SSD fixation method, I/O BKT and I/O modular design are optimized to eliminate the need for auxiliary BKT assembly. In addition, Center Hook and WLAN were integrated on MB, and their assembly was cancelled, so that the design of the optimized parts was more integrated and modular. Then, the optimized product was rearranged for production. The CWS value of the optimized product was 0.1589, which decreased by 27 % compared with that before optimization.","PeriodicalId":314911,"journal":{"name":"Journal of Mechatronics and Artificial Intelligence in Engineering","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123606417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It ensures a smooth flow of goods, products and services. In the modern global setting, supply chains have become more complex and inclusion of technology is providing great benefits. Robust technology is needed for identification, tracking and monitoring of the various goods and assets during the supply chain. One such emerging technology for this is RFID sensors. RFID is a popular wireless technology capable of collecting, storing and transmitting data and thus identifying, tracking and communicating. The two main components of RFID systems are tags and readers each of which perform a crucial and specific function. Tags are basically the memory, storing data received by the reader. Readers retrieve the data and transmit it to tags using an antenna. RFID technology has greatly replaced its counterpart and competitive technology- barcodes, in supply chains. It provides various benefits as compared to barcodes due to which it has got increased attention in various fields such as supply chains, healthcare, agriculture, food industry, manufacturing, libraries, security etc. Supply chain management deals with the flow of activities or processes included in any business, production activities. During this entire journey from raw material procurement to final dispatch a number of smaller supply chains are included each of which are critical. RFID technology has been largely deployed in supply chain management in order to identify, track and store information. These RFID systems enable real time monitoring of the supply chain and gives an upper-hand as compared to barcodes. RFID systems are not only used for storing and retrieving product data but also to monitor and track the flow of the entire supply chain. In the case of cold chains, RFID systems are used for maintaining the environment needed for ensuring quality of food products. Various such applications of these sensors in supply chains have been identified and deployed, However, still this technology remains to be dormant to some extent in supply chain industry. This review paper is aimed at doing a thorough literature review of RFID technology, its deployment in the supply chain domain, and challenges faced.","PeriodicalId":314911,"journal":{"name":"Journal of Mechatronics and Artificial Intelligence in Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130113229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The surrounding environment of the foundation pit is complex, involving many buildings, the construction is difficult, and there is a great risk of construction safety. The effective control of the structural deformation of the existing subway station is the key to selecting the underground enclosure structure and construction process of the surrounding post-construction projects. Combined with the actual situation of the project, the three-dimensional numerical analysis method is used to analyze the impact of the construction of the foundation pit of the building on its adjacent structures in detail, and the relevant treatment measures are proposed. The research shows that the unloading effect caused by the large-scale excavation causes the soil outside the pit to move towards the inside of the pit. Under the influence of the soil deformation transfer effect, the Beiguan Station of the R1 line subway produces certain rebound, settlement and horizontal displacement, but the values of each deformation index are within the deformation control standard, the numerical analysis considering the influence of small soil strain can better reflect the influence of foundation pit excavation on the displacement, deformation and internal force of the existing structure. It can better match the actual engineering experience.","PeriodicalId":314911,"journal":{"name":"Journal of Mechatronics and Artificial Intelligence in Engineering","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116473255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the expectations of the children from robots to interact like humans are huge. This study presents a general model for understanding the natural language in human-robot interaction by applying Generative Pre-trained Transformer (GPT) language models as a service in the Internet of Things. Thus, the physical presence of the robot can help in fine-tuning the GPT model by prompts derived from the environmental context and subsequent robot actions for embodiment understanding of the GPT outputs. The model uses web or cloud services for Natural Language Processing (NLP) to produce and play human-like text, question answering or text generation. Verbal questions are processed either via a local speech recognition software or via a Speech-to-Text (STT) cloud service. The converted question into machine-readable code is sent to one of the GPT language models with zero- or few-shot learning prompts. GPT-J model has been tested and deployed either in the web or cloud with options for varying the parameters for controlling the haphazardness of the generated text. The robot produces human-like text by using Text-to-Speech (TTS) cloud services that convert the response into audio format rendered on the robot to be played. Useful requirements how the model to be used in order to be feasible were determined based on the evaluation of the outputs given from the different NLP and GPT-J web or cloud-services.
