Anthropogenic impacts on the Glowworm Cave, Waitomo, New Zealand: a microclimate management approach

Waitomo Glowworm Cave is a highly visited cave where the highlight is viewing the bioluminescence display of a large colony of glowworms. The visitation levels result in the build-up of anthropogenic CO2, to the extent that it could cause corrosion of speleothems. The cave experiences chimney-effect ventilation with air flowing either upward or downward through the main cave chambers depending on air density differences between the cave and the outside environment. Lack of airflow leads to CO2 build-up; however, unrestricted airflow can draw in cool, dry air which is harmful to the glowworms. Consequently, airflow is managed by controlling the opening and closing of a door that seals the upper-most entrance, preventing ventilation under drying conditions and promoting ventilation when it is necessary to clear CO2 and when inflowing air has high relative humidity. A network of microclimate sensors in the cave allows prediction and management of the ventilation pattern. Management leads to asymmetric airflow through the year, which has a flow-on effect on cave temperature. Microclimate monitoring supports the current management practices that use door control to enhance cave ventilation when people are in the cave. Suppressing airflow, especially in winter, reduces the introduction of dry air.

Access Control and Security System Via Bluetooth Application on Android Smartphone

Smartphone technology can be applied not only to establish communication needs but also to support other purposes. One of them is related to personal safety and security functions. It is undeniable that criminal acts can occur anytime and anywhere. Even in a private or residential area, theft could happen. Smartphone and sensor technology can be used as a solution to encounter this problem. In this case, it can be utilized to improve the security control system of the gate or garage door at home. This research presents a prototype of a gate and garage door control and security system that operates through an application on an android smartphone. The application of HC-05 Bluetooth is used to send signals from the smartphone to the Arduino Uno microcontroller, while the micro servo acts as a locking mechanism on the gate itself. The buzzer function is presented to notify homeowners when the gate or garage door is open for more than 15 seconds. This prototype can control gates and garage doors with an average connection time of only about 5 seconds. Thus, this prototype is feasible to use as an alternative to control and improve housing security systems.

A bidirectional and low-frequency energy harvester for collecting human crowd energy in shopping malls

Human crowd kinetic energy is a promising electricity source in shopping malls. Harvesting human crowd energy can supply considerable power for lighting and door control. In this study, a bidirectional low-frequency energy harvester was proposed, analysed, fabricated, and tested. The harvester was mainly composed of a hinge, four one-way bearings, one sun gear, one internal gear, one planetary gearbox and one direct current motor. The hinge was used to connect the door. The combination of these one-way bearings, hollow shaft, solid shaft and gears transformed the bidirectional movement into unidirectional movement. The utilization of the planetary gearbox boosted the velocity of the door movement to overcome the low-frequency problems. The motor generated a varied direct current voltage. A theoretical analysis was performed to ascertain the factors that would determine the energy harvester’s performance. A full-size prototype was fabricated, a simulated shopping door environment was created, and experiments were investigated. The simulation results correlated well with the experimental results. At an ultralow door movement (45°/s), the harvester can output an open-circuit voltage of 7.4 V (steady voltage) and a power of 3046 mW. The harvester had a high efficiency up to 56.79%. The harvested voltage can power electronic locks, LED billboards and wireless doorbells, all of which are necessary apparatuses in shopping malls. The proposed harvester can potentially be used in shopping malls to harvest plentiful human crowd kinetic energy.

Vehicle Door Opening Control Model Based on a Fuzzy Inference System to Prevent Motorcycle–Vehicle Door Crashes

The goal of this research is to develop a fuzzy logic-based vehicle door control system to avoid motorcycle–vehicle door crash accidents. Accidents of this nature usually occur when the driver has parked the car, opens the door getting out of the car and collides with a motorcycle approaching from the rear, causing injury to the motorcyclist. In order to prevent such accidents, the fuzzy logic control system inputs the speed (MS) and safety distance (SD) of the motorcycle approaching from the rear, and then the fuzzy inference unit (FIU) calculates the clear output (Crisp) defuzzification Vehicle Door Opening Model (VDOM) value for the central locking system of the car, which can be used to trigger three modes, namely Danger Mode, Caution Mode and Warning Mode. In this study, the VDOM system is designed to trigger reasonable, reliable and consistent door control under different speeds of motorcycles coming from the rear and will be effectively applied to the door control of semi-automatic cars in the future.

Checking SysML Models Against Safety and Security Properties

Systems engineering, or engineering in general, has long been relying on document-centric approaches. Switching to model-based systems engineering, or MBSE for short, has extensively been discussed over the past three decades. Since about two decades, MBSE has been commonly associated with the modeling language SysML (Systems Modeling Language), which offers a standardized notation, not a methodology of using it. SysML needs therefore to be associated with a methodology supported by tools. In this paper, a methodology supported by the free and open-source software TTool is associated with SysML. This paper focuses discussion on methodological issues, leading the authors to share their experience in real-time systems modeling. Modeling with SysML is more than just drawing the different diagrams. Associated tools offer possibilities to analyze SysML models for specific properties. In this paper, verification addresses both safety and security properties. The TTool model checker inputs the SysML model enriched with safety properties to be verified and outputs an yes/no answer for each property. Security verification checks SysML models against confidentiality, integrity, and authenticity properties. As an illustration of the proposed approach, an aircraft cockpit door control system is modeled in SysML and verified against safety and security properties.

Optimized control design of sliding plug door for high-speed EMU

With the continuous improvement of people’s requirements for the convenience of going out, high-speed EMUs came into being. As one of the important components of the high-speed EMU, the sliding plug door is located at the junction between the carriage and the carriage, and is one of the important passages for passengers. When the EMU is running at high speed, once the control system fails, it will cause damage to the personal safety and interests of passengers. Therefore, as the speed of the EMU increases, the stability of the electric end door control system of the EMU also needs to be enhanced. First, analyse the motor drive process of the sliding plug door control system, design the sliding plug door control system at the hardware level, and build an experimental platform for analysis and testing. Because the operating environment of high-speed EMUs is very complicated, in order to make the sliding plug door control system work stably for a long time, it is necessary to analyse the overall process of the sliding plug door opening and closing movement in stages, and adopt fuzzy-PID combined control. The algorithm further optimizes the movement process. The control method of the brushless DC motor is digital control, and the rotation speed of the motor is controlled by controlling the duty ratio applied to the motor side. Finally, through experimental testing, it is verified how the fuzzy-PID combined control algorithm can improve the stability of the door opening and closing movement.
