Home Appliances (HA) factories commonly use fire combustible materials in manufacturing process, such as paper and plastic. When the fire occurs, the flammable materials rapidly and excessively heat and smoke. Lack of fire management plan can result in property damage and casualties. Thus, it is essential to evaluate risk from fire in order to plan for fire evacuation properly. In this study, we aim to simulate fire in HA factory comprised of industrial area, storage space, and offices., The Fire Dynamics Simulator (FDS) software called PyroSim is used to analyze the simulated fire; in which the spread of smoke, the temperature profile, the potential visibility, and CO2 are analyzed. The initial results show that the fire-smoke will spread very rapidly and can completely block the visibility of the escape routes from the fire room after about 4 minutes from when the fire occurs. This study is expected to not only give an understanding of fire characteristics, but also to make a proper decision regarding fire protection designs and to assess evacuation plans.

Nowadays, Internet of Things or IoT is gaining popularity. However, the process to set up the IoT platform is complex and time consuming for some IoT developers. Thus, this paper presents the design and development of an MQTT-based IoT cloud platform with flow design by Node-RED to help developers save time to set up the IoT platform by themselves. The user interface of this platform is in the form of a web application developed with the MERN stack. The platform provides three main services: (1) MQTT broker for data transmission (2) Node-RED for designing the flow of data processing and displaying data in graphical form via Dashboard and (3) InfluxDB and MongoDB databases for storing data. These services operate as containers running on the Docker. The web application connects to the Docker via Docker API using the Dockerode library to start, stop and get the status of the containers. Using the test by making an IoT system for monitoring and displaying temperature values, we found that our platform can support and help users in developing the IoT system very well. The developers who want to develop IoT systems do not need to set up an IoT platform by themselves.

In this paper, the 64.57 mm x 112.53 mm x 1.6 mm hexa-band monopole reconfigurable antenna is designed and simulated. The proposed antenna can be operated within the range of 660 MHz–3.56 GHz. It can be switched the resonance frequencies between the tri-band at 915 MHz ISM standard, 2.3 GHz WiMAX and 3.6 GHz 5G standard and the another dual band in candidate 5G standard, which are 700 MHz and 3.45 GHz for an OFF and ON state single PIN switch diode, respectively. In addition, the 1.3 GHz resonance frequency is also achieved for the ON state PIN switch diode. The impressive return loss and gain as well as the radiation patterns are observed from the simulation results.

The Bangkok Bank at King Mongkut's University of Technology North Bangkok (KMUTNB) has always been crowded, so the waiting time for each customer to be served has become a major concern. In this study, the current queueing system with a single queue and three service channels is considered by collecting the data in three periods, 8:30 a.m.–10:30 a.m., 11:30 a.m.-1:30 p.m. and3:30 p.m.–5:30 p.m. from 2nd September to 27th November 2015. Moreover, the new queueing systems are considered by increasing or decreasing the service channels and changing the queueing structure from single queue to multiple queue. The average waiting time, the average total time, the average queue length and the average work in process are considered as the key performance measures in order to show the efficiency of the service. The simulation results, by using the Arena program, show that the appropriated service for the first time period, 8:30 a.m.–10:30 a.m., is the queueing system with the single queue and three service channels. In addition, the appropriated service for the second time period, 11: 30 a.m.–1:30 p.m., is the queueing system with the single queue and four service channels. Finally, the appropriated service for the third period, 3:30 p.m.–5:30 p.m., is the queueing system with a single queue and two service channels.

In order to study the control theory, students need to learn about basic theories that are sometimes difficult to understand. Only in-class lecturing is not enough, and hand-on practices are very important, in which theory and practice can be integrated to create knowledge and skills simultaneously. Although there are many learning tools available for practicing with sample exercises, they are not enough for students to understand properly especially in the subject that are abstraction and requires imagination. This paper presents a didactic tool for a study of leveling control system which maintains the surface level using multiple sensors including IMUs and ultrasonic sensors, and multiple models including digital filters, coordination, digital automatic control, and kinematic model. The data obtained from the IMU are used to calculate the tilt angle using the complementary filter method, and from the ultrasonic sensors are used to find the distance between the platform and ground using low-pass filter. The difference tilt from both roll and pitch angles and the distance are used to control the tilt angle and the correct distance using the PID controller. This system can be used to study IMU sensor functions, digital signal processing and digital controller as well, and will enable students to understand and use the sensor system to easily create automatic control systems in the future.

This paper focuses on the application of administrative control which utilizes the job rotation to prevent workers from occupational hazards at the workplace. In the unsafe workplace, workers in the job rotation program will be assigned to workstations with low or high occupational hazards so that 8-hour exposure to each hazard of all workers will not exceed the permissible exposure limits. When dealing with a high hazard level, the number of workers required for job rotation is possibly more than the number of workstations because some workers in some periods will be assigned to perform tasks in the safe areas. Therefore, this paper proposes the optimization approach to solve the mixed-integer programming models that try to minimize the number of workers used in job rotation under noise hazard and air contamination. The numerical experiments are provided to demonstrate the solution procedures. Finally, the effectiveness of the branch and cut search in an optimization software namely CPLEX is also discussed. Within the computational limit, CPLEX can determine the optimal solutions for small size problems and the feasible solutions for large size problems.

The use of worn cutting tools has a detrimental effect on the finished quality of a workpiece, tool precision, and internal machine stress. Worn tools also decrease productivity through unplanned stops, tool changes and increase the production of scrap material. This study investigates an inexpensive and non-intrusive method of inferring tool wear by measuring the audible sounds emitted during a milling process. Operation sound of S50C steel, which was square shoulder milling with HSS endmill using a computer numerical control (CNC) milling machine, was recorded by a microphone directly connect to data acquisition hardware. The audio signature was examined using a spectrogram, and the extracted sound features of the milling tool in the frequency and time domain were used to correlate with tool wear. The results indicated that the mean sound pressure magnitude was related to tool wear, but although the magnitude of mean cutting sound significantly increased in accordance with tool wear progression.
