Abstract

Around 22-33% of medical waste is contributed to the disposal of surgical tools. With over 310 million surgeries carried out annually, the burden of surgical tool waste becomes critical in terms of cost and effort in approaching zero net waste. Among the most common surgical waste is surgical scissors, often disposed of due to corroded surface, fracture, or loss of functionality. Since surgical scissors play such a major role in dissecting various organs, the reduced quality results in bleeding, uneven cutting, and contusion and enhances the risk of site infection. One way to reduce the amount of surgical waste is by enhancing durability achieved by applying surface modifications, such as coating. This paper reviews three surface modification approaches for surgical scissors coating, namely (1) anodized coating, (2) thin metallic glasses, and (3) chemical vapor deposition. Some experimental data from the reported studies were summarized to assess the potential methods to enhance surgical scissors' durability and reduce medical waste. Keywords: surgical scissors; durability; medical waste; CVD, thin metallic glasses. Anodized aluminum.

Abstract

There is a few simulation environment to implement the Preisach model of magnetic hysteresis. In this simulation, the changes of magnetic field strength and magnetic flux density will be observed. Magnetic hysteresis are commonly used in ferromagnetic and ferrimagnetic material analysis. The relationship between magnetic field strength and magnetic flux density is then represented in a B-H curve. The idea is that the B-H curve will be analyzed using Preisach model. Then, the data that is obtained could be analyzed further. Keywords: Preisach Model

Abstract

This thesis aims to develop the system setup for the Pre-Charging Insulation Test conducted in a DC EVCS utilizing Raspberry Pi 4, DPM750/20C, and SIM100MOD, with CAN Bus communication protocol as its communication means. The problems addressed in this thesis are the rarity of the implementation of standard SNI IEC 61851- 23:2014, the studies in Pre-Charging Insulation Monitoring using integrated modules because of the low number of electric vehicles and their infrastructure, especially for DC Chargers, and the incompatibility between devices when integrating the necessary components to perform the pre-charge insulation test according to the standards. The pre-charge insulation setup is developed by integrating the Raspberry Pi 4 with 2- CH CAN HAT Module as the charge controller, DPM750/20C as the EV power module, and SIM100MOD as the ground fault detector. The setup will then perform the pre-charge insulation test procedure according to the SNI IEC 61851-23:2014. The setup development for the pre-charge insulation test has succeeded. The data obtained from the performed pre-charge insulation tests shows that the components could communicate despite the differing baud rate requirements and that the pre-charge insulation test procedure can detect the insulation faults and act accordingly in the event of ground faults. Keywords: Charging Station, Pre-Charge Insulation Test, SIM100MOD Ground Fault Detector, CAN Bus Communication, DPM750/20C Power Module, Raspberry Pi 4

Abstract

The purpose of this thesis is to design integration, development and functional verification of communication system between DC charging station controller and electric vehicle communication controller by using Power line Communication (PLC) module, Raspberry Pi 4, Pulse Width Modulation (PWM) converter circuit, and CAN Bus communication protocol. The problems that this thesis attempts to solve are transmitting High-Level Communication digital signal data passed through a Low-Level Communication conductor without interfering with one another. Low-Level Communication is in the form of an analog control pilot Pulse Width Modulation (PWM) signal, the signal with a frequency of 1 kHz is used in AC Charging Station. In certain cases, AC Fast Charging and DC Fast Charging require High-Level Communication in the form of digital signal data, this digital signal data is sent using the CAN Bus Protocol with a baud rate of 500 kbps. The communication system between the DC charging station and electric vehicle setup is developed by integrating Raspberry Pi 4 with 2-CH CAN HAT Module as the DC Charging Station Controller and Electric Vehicle Communication Controller, SICON EMI EVPLC Module as Power Line Communication (PLC) Module, and PWM converter circuit as PWM signal converter. According to IEC 61851-1:2017, this setup will carry out the communication system between a DC charging station and an electric vehicle. The setup of communication between the DC charging station and the electric vehicle has been successfully developed, and the Power Line Communication module used in this thesis is successful in transmitting High-Level Communication through a Low-Level communication conductor. The CAN data that has been sent and received by controllers shows the components used in this communication system are successful. Keywords: Electric Vehicle, Charging Station, Power Line Communication, High-Level Communication, CAN Bus Protocol, Pulse Width Modulation, Raspberry Pi 4.

Abstract

Solar panels are commonly used to replace power sources like fossil fuel. The usage of solar panels is because it is eco-friendly to the environment and can keep producing electricity freely as long as there is sun ‘s light. Although there is a downside for solar panels, it is still a safe choice for producing or replacing any kind of power source. This research gives the details related to solar panel power and includes the usage of the solar panel to the household appliance. The main content of this paper is monitoring, analyzing, measuring Solar PV panel DC power output and using Arduino based modules to do the monitoring, analyzing, measuring for this research. After the measuring and analyzing the output, this result can give the researcher to achieved and accurate result of the DC power output of the solar panel and can be used for industrial purposes and household appliances and also monitoring that are created on LCD can be used for maintenance if there is in need for maintenance, so that the power output can be check all the time automatically without physical interference.

Abstract

A good sleep quality and quantity is essential to achieve a healthy body and mind. Hyperbaric oxygen therapy (HBOT) is a treatment involving a specialized chamber where pressure and pure oxygen will be supplied, which can influence inflammation, oxidative stress, cortisol, and melatonin, which may influence sleep quality. Therefore, the purpose of this study is to identify if there is a significant and positive correlation between hyperbaric oxygen therapy and sleep quality. In this study, participants’ sleep quality is assessed by Pittsburgh Sleep Quality Index before and after undergoing HBOT treatment. The participants are also divided into 5 groups based on the number of HBOT treatment that they have undergone. The result of this study is that there is a significant positive correlation between hyperbaric oxygen therapy and sleep quality (p-value<0.001), along with sleep quantity (p-value<0.001). And subjects can acquire the best sleep quality after more than 41 hyperbaric oxygen therapy at 3 ATA (p-value <0.07). Keywords: Hyperbaric Oxygen Therapy; Sleep Quality; Sleep Quantity; PSQI

Abstract

This research paper, entitled "Improving the Testing of Sportirena through Personalized Selenium Automation Tools," highlights the urgent requirement for automated testing within the Sportirena platform. In a similar manner to enhancing fire resistance in composite sandwich panels, which aims to strengthen against potential dangers, our investigation concentrates on enhancing the reliability of Sportirena's application. We have developed customized automation tools, comparable to the addition of fire retardants, utilizing Selenium, with a specific focus on user authentication. The results demonstrate significant improvements in testing efficiency, coverage, and defect detection when compared to manual techniques. The insights obtained from existing literature support our findings and validate the chosen methodology. By drawing parallels between fire resistance in composite panels and automated testing in Sportirena, this study contributes to the overall objective of ensuring safety and resilience in intricate systems. Keywords: testing, efficiency, coverage, and defect detection.
