Owing to the increasing applications of electronic systems in radiation environments such as medical radiation therapy, non-destructive testing, milling, nuclear power plant control etc., and their failures can have significant impact to the surrounding and human, their reliabilities under radiation are of crucial importance. While radiation effects on individual electronic components are well studied, the reliability of entire electronic systems in radiation environments is less understood due to the difficulty of identifying dominant failure mechanisms or failed components in a complex electronic system. This is because radiation damages on electronic components generally do not have obvious sign for identification, and desoldering every component for detailed analysis is impractical. In this work, we developed a method combining reliability statistics with the physics of failure to classify and identify failure mechanisms. Detailed failure analysis confirmed the accuracy of the method. This study focuses on a gps tracking system for vehicles carrying radiation sources. Identifying failure modules within the system allows the determination of reliability functions of gps with respect to each failure module, facilitating the selection of appropriate gps systems and predicting optimal replacement times to ensure continuous vehicle monitoring. This method also allows electronic system designers to select reliable modules to assure high system reliability.

Energy harvesting systems have been piloted in this experimental paper. The proposed system uses ten-watt solar panel for static base photovoltaic (PV) and a two-orientation sun follower system. Application of gps (global positioning system) in sun following arrangement ensures the best potential output power from solar radiation. By tracing the sun's trajectory across the sky over the course of the day, the gps-based two-orientation sun following system has been able to record maximum sunlight intensity from 6:00 to 18:30 solar time. The two-axis sun follower system with gps has a higher engrossed power than the light-dependent resister (LDR). Two-axis gps, LDR tracker and the static base panel produce the average energy of 146.7 Wh, 82.45 Wh and 42.79 Wh on a sunny, hazy and rainy day, respectively. The solar panel used here is flexible, which uses 15. of step tracking to reduce system power consumption. The experimented result of 2021 states that the average amount of energy produced by the two-axis-gps sun following system was 4.021754Wh/day, which is 45.85% and 14.93% more than the average amount of energy produced by the static base and LDR base PV system, respectively. This novelty emphasizes system with minimum power consumption to generate maximum power. Here, the gps will provide the extreme accurate trajectory of sun path. The flexible panel with lightweight reduces power consumption of tracker. And finally the 15. or discontinuous tracking reduces the power consumption as used in continuous tracking.

The implementation of a Location Service for Emergency Medical Services system (LS4EMSs) is the goal of this study. by integration of pgRouting algorithm, Web Map Application, and Geo-IoT devices. The study is divided into 2 parts: (1) design of a security emergency incident location alarm system that can be used to track security emergencies in real time using Geo-IoT and (2) development of Emergency Routing Service (ERS) system based on web map application. NodeMCU ESP8266 and U-blox Neo-6 m gps module were used for implementing Geo-IoT which can connect to Wi-Fi and give information including the location of the push button triggered by an individual in an emergency. ERS can determine the best route to take from the hospital or closest ambulance to the location where the Geo-IoT device is located. Free and Open-Source Software for Geospatial (FOSS4G) stack was used in the system's development, since it is easily adaptable to cover different purposes, including fire, flood, or other transport movements. The Integration of Geo-IoT and Web Routing Service for LS4EMSs improves utility as it is a near real-time ERS system.

There is no denying that public transportation is and will continue to be a part of a commuter's daily life as it serves as a quick and easy way to reach their destinations. However, it holds its own disadvantages, such as unpredictable arrival times, poor comfort and safety, and disorganized queues. Research shows that in Metro Manila, Jeepneys are the second most used public transportation, making up 19.1% of all journeys. Additionally, 7,000 out of 150,000 jeepneys are electric or contemporary models. To eliminate challenges faced by the current transportation system, this research paper was proposed to develop a real-time gps tracking and ETA system, and an Android App to access data for E-Jeeps in Quezon City, Metro Manila. Tests were conducted and results show that the gps tracking system generated a percentage error of 0.0017%, making the system accurate and reliable. Whereas the ETA system resulted in an average delay of 1 minute and 35 seconds for all trials. © 2024 IEEE.

For both long-distance and suburban traffic, railroads offer the least expensive and most practical form of passenger transportation. In addition, India's railway system handles most of the country's carriers. The main issue about railway track crossings and undetected cracks in Indian railway tracks is still accidents. Approximately 60% accidents happen at railway crossings and also due to rail track fracture, which costs both valuable lives and money. Therefore, it is necessary to consider new technology that is reliable, effective, and steady for detection on railway tracks. This project's primary goal is to develop a successful functioning prototype that can detect the railway track cracks utilizing LIDAR sensors, employing a dynamic approach that integrates gps tracking and WIFI modules to transmit alert messages along with the geographical coordinates of the location. An Arduino Uno is employed to manage and synchronize the functionalities of these devices. LIDAR, a remote sensing technique, measures distance by analyzing the time-of-flight (TOF) of unmodulated narrow light pulse echoes reflected from the target. © 2023 IEEE.

Efficient and timely accident detection systems are imperative due to the rising global incidence of road accidents. Conventional approaches rely on eyewitness reports or calls to emergency services, leading to delayed responses and inaccurate information. The critical period immediately following a traumatic injury, often referred to as the 'golden hour,' underscores the importance of swift medical attention, with the highest likelihood of saving a patient's life within the first 60 minutes. Beyond this timeframe, mortality rates significantly rise. Presently, the delays in notifying local hospitals contribute to increased mortality rates. Hence, the primary objective of the project is to mitigate these adverse outcomes and eliminate delays in conveying information to nearby hospitals. Upon project implementation, the accident site will be promptly communicated to the hospitals. Currently, individuals at the scene of an accident are not required to notify hospitals, leading to potential delays. The proposed model integrates an Arduino UNO microcontroller, gps, GSM module, and a buzzer. The gps determines the accident's coordinates, while the GSM module sends SMS notifications, including accident type and location via Google Maps. A MEMS accelerometer sensor detects the accident occurrence. This system ensures that not only hospitals but also the victim's family is promptly informed, potentially saving crucial minutes that can make a difference in saving a life. © 2023 IEEE.

The number of vehicular accidents has increased significantly in comparison to previous time periods. An estimated seventeen crashes occur every hour. Bicycle accidents account for a sizable proportion of all accident incidences. This is due to the fact that two-wheeled vehicles lack a number of safety measures seen on automobiles and tractors. This paper outlines the methods for disaster mitigation through the creation of an effective system that quickly identifies and alerts the appropriate authorities and individuals. The accelerometer assesses potential accidents by measuring head tilt. Vibration sensors are capable of detecting collisions and sending out timely warnings about potential hazards. When the engine is turned off, the MQ3 monitor sends a text message to the rider's mobile device. The failure to wear a helmet significantly increases the risk of brain injury during an accident. Within the constraints of this unique situation, the use of a helmet may help to reduce the severity of head injuries. The quick installation of a level monitor has the potential to drastically prevent gas theft. The gasoline theft detection sensor is located at the fuel tank's aperture. The speed-regulating system functions as an independent turbine. The emission of an aural signal, also referred to as an "overspeed beep," serves to notify the operator when they have exceeded a predetermined velocity threshold. The spinning of the turbine motor indicates the speed of the bicycle. Incidents have occurred as a result of the presence of an unusually large number of people. The installation of a load cell sensor may be considered to reduce the risk of vehicle overload. Data on distances, velocities, fuel consumption, and miles were collected and saved using the Internet of Things (IoT). © 2023 IEEE.
