Developed Smart Vehicle Tracking System using GPS and GSM Modem

 Fast technological development has streamlined daily living. On the other hand, as a result of a shortage of emergency services, the growth of technology has also increased the incidence of traffic accidents, which cause enormous loss of life and property. Systems for monitoring vehicles and detecting accidents are highly dependable and secure, and they are especially useful for remotely monitoring vehicle activity. In this paper, based on the Global Positioning System (GPS) and the Global System for Mobile (GSM) Communication has been implementing, an effective system for monitoring vehicle movement and identifying any accidents that occur has been established GSM. The suggested method successfully made use of widely available hardware elements that integrate a smartphone and a vehicle unit that is mounted within the car. The proposed system would use General Packet Radio Service (GPRS) to automatically communicate and store vehicle data to the Internet of Things (IoT) every 10 seconds. In addition, the system will create an SMS Short Message Service (SMS) and send it to the user's smartphone in response to an SMS request received with the vehicle's current position information. At the user side, it has been an android smartphone for software application connected to the Thinger.io platform that has been used to view up-to-date car information. Only the authorized user who has access to the Thinger.io platform and the login and password may access this application due to its security. The suggested system's accuracy has been evaluated. The findings show that the suggested method can follow the vehicle high accurately.

Druken alcohol intelligent detection system IoT based Arduino controller

An intelligent alcohol detection system has been created to recognize the location of drunken drivers to prevent such road incidents. The project is being enhanced to use the internet of things (IoT) to make it easier for users to track their location and receive messages through their smartphones. The alcohol breath analyzer sensor detects the amount of alcohol in the driver's breath and the liquid crystal display (LCD) will display "Alcohol Detected" and the blood alcohol concentration (BAC) value if the level exceeds the threshold. İn addition, the global system for mobile (GSM) will send short message service (SMS) or make phone calls and telegram will sends BAC value, while the GPS will broadcast the discovered alcohol's location. This project implicitly provides more benefits for current efforts in the development of accident prevention systems in the hopes of putting them into practice in the real world to improve road safety.

E-Application for Women Defense

In this current era, women are prone to multiple safety issues. In every three women, one is a victim of such violent acts. There are multiple programmes to make them aware and strong enough to face the situation, but not every woman is doing it. Crimes will also increase as the response to the act weakens. So, considering these circumstances, we used modern technology to support women with these problems. Violence can negatively affect women’s physical, mental, sexual, and reproductive health and may increase the risk of acquiring HIV in some settings. We proposed a concept with GSM (Global System for Mobile) and GPS (Global Positioning System) built in. When the incident occurs, the alert signal is triggered with the press of a button, and the location is sent to the police officers. It also has a camera that can livestream the face of the person who committed the crime, as well as a handy defence tool to protect herself from the criminal. We can make women a little stronger through this project, although they are already strong enough.

Intelligent Deep Learning Enabled Wild Forest Fire Detection System

The latest advancements in computer vision and deep learning (DL) techniques pave the way to design novel tools for the detection and monitoring of forest fires. In this view, this paper presents an intelligent wild forest fire detection and alarming system using deep learning (IWFFDA-DL) model. The proposed IWFFDA-DL technique aims to identify forest fires at earlier stages through integrated sensors. The proposed IWFFDA-DL system includes an Integrated sensor system (ISS) combining an array of sensors that acts as the major input source that helps to forecast the fire. Then, the attention based convolution neural network with bidirectional long short term memory (ACNN-BLSTM) model is applied to examine and identify the existence of danger. For hyperparameter tuning of the ACNN-BLSTM model, the bacterial foraging optimization (BFO) algorithm is employed and thereby enhances the detection performance. Finally, when the fire is detected, the Global System for Mobiles (GSM) modem transmits messages to the authorities to take required actions. An extensive set of simulations were performed and the results are investigated interms of several aspects. The obtained results highlight the betterment of the IWFFDA-DL technique interms of various measures.

Identification of Cellular Signal Measurements Using Machine Learning

Spectrum awareness has a plethora of civilian and defense applications, such as spectrum resource management, adaptive transmissions, interference detection, and identification of threat signals. This article proposes an identification neural network (INN)-based model that identifies cellular signals from three different radio access technologies, namely global system for mobile (GSM) communications, universal mobile telecommunications service, and long-term evolution. The proposed INN identifies whether or not the measured power spectral density belongs to a certain cellular signal type. Two data collection approaches (DCAs) are considered: in-band and multiple-band. The over-the-air measurements for the two DCAs show that with low computational complexity, the proposed INN model provides an identification accuracy between 93% and 100%, with a false alarm (FA) rate between 0% and 10%.

Design and performance analyses of graphene-nano plasmonic devices for wireless gas sensor applications

Graphene gained more attention in industrial applications owing to its unique characteristics. A simple and inexpensive photodeposition technique was used to fabricate the nanoparticles. Herein, ZnO, Au/ZnO, and the neat rGOx@Au/ZnO heterostructure plasmonic nanocomposites were applied to detect the sensitivity of CO2, LPG, and O2 gases using a sensing device with a rapid response at ambient temperature. The gas detection mechanism explains the synergistic influence between the localized plasmonic phenomena of AuNPs and the π-π interaction among rGOx/ZnO. Compared to pure ZnO and AuNPs/ZnO nanocomposite, the sensing response of rGOx@Au/ZnO (x = 10 wt %) exposed to CO2 gas is optimized, achieving a response of 625.63% over a 16-s reaction time at room temperature. The heterostructure's morphological, crystal structure, and electronic properties were determined using different techniques. The devices were exposed to various gases such as CO2, O2, and liquified petroleum gas (LPG) to test the selectivity of the composite sensor, and the sensor response for these gases was measured and significant. A wireless gas detector can be built using an Arduino module. The circuit is created by connecting a gas sensor to an Arduino rGOx@Au/ZnO (x = 10 wt %) weight board, which determines the gas content in the air and whether it exceeds the allowable value. At the level programmed in the Arduino kit, Global System Mobile (GSM) sends an SMS to the cell phone number that was also investigated.

A Wireless Autonomous Real-Time Underwater Acoustic Positioning System.

Recent acoustic telemetry positioning systems are able to reconstruct the positions and trajectories of organisms at a scale of a few centimeters to a few meters. However, they present several logistical constraints including receiver maintenance, calibration procedures and limited access to real-time data. We present here a novel, easy-to-deploy, energy self-sufficient underwater positioning system based on the time difference of arrival (TDOA) algorithm and the Global System for Mobile (GSM) communication technology, capable of locating tagged marine organisms in real time. We provide an illustration of the application of this system with empirical examples using continuous and coded tags in fish and benthic invertebrates. In situ experimental tests of the operational system demonstrated similar performances to currently available acoustic positioning systems, with a global positioning error of 7.13 ± 5.80 m (mean ± SD) and one-third of the pings can be localized within 278 m of the farthest buoy. Despite some required improvements, this prototype is designed to be autonomous and can be deployed from the surface in various environments (rivers, lakes, and oceans). It was proven to be useful to monitor a wide variety of species (benthic and pelagic) in real time. Its real-time property can be used to rapidly detect system failure, optimize deployment design, or for ecological or conservation applications.

The Effect of Tropospheric Scintillation on Microwave Frequencies for GSM System in The Iraqi Atmosphere

Several papers have been published recently on the effects of scintillation on microwave propagation in standard atmospheres. Most of them have analyzed theoretically the influence of various parameters on the propagation, but barely a few researchers were able to extract the results from the model relying on microwave links in a nonstandard atmosphere. A method is proposed to predict the tropospheric scintillation on the space path of Earth for both standard and nonstandard atmospheres using the frequency range (20-38) GHz which is used in the Global System for Mobile (GSM). This method can be applied to the different atmospheric conditions in different regions. This work studied the effects of various parameters, such as antenna diameter, meteorological elements t (average temperature), H (relative humidity), and water vapor pressure and frequency, on the scintillation magnitude of GSM bands in Basrah and Baghdad.

A practical radio frequency fingerprinting scheme for mobile phones identification

Radio frequency fingerprint (RFF) has attracted a remarkable surge of attention to wireless transmitter identification due to the inimitable hardware imperfection. However, most RFF-based schemes devised in controlled environments are unable to reach the claimed performance in real-world scenarios. This paper proposes a practical RFF identification method for mobile phones in Global System for Mobile (GSM) system. Specifically, the instantaneous amplitude of near-transient part in normal burst (NB) is regarded as RFF that extracted from up-link communications. In addition, an anomaly filtering and stacking (AFS) method is introduced to obtain stable RFF in Time Division Multiple Access (TDMA) system. Lastly, the impacts of frequency point and sending power variations on RFF are fully dissected in comparison experiments. Experiments on 10 mobile phones show that the proposed RFF scheme yields 99.17% True Acceptance Rate (TAR) in real wireless environments. Experiments also show that the varying transmission power decreases the accuracy of RFF identification.

Methodological Skills Required By Instructors in Radio Television and Global System Mobile Servicing in Vocational Centers in Gombe State, Nigeria

The study's primary goal was to evaluate the methodological skills required by instructors in Radio Television and Global System Mobile Servicing in Vocational Centers in Gombe State, Nigeria. The study used a descriptive survey research approach and was carried out in Gombe State, Nigeria. 55 respondents made up the study's population, including 42 teachers and 13 principals. There was no sampling because the population was of a manageable size, hence whole-population-sampling technique was employed for the study. The structured questionnaire "Questionnaire on the Appraisal of Skills Required by Instructors (QASRI)" designed by the researchers served as the instrument for data collection. The instrument was validated by three professionals, and Cronbach Alpha yielded a reliability value of 0.72. The mean statistics were utilized to answer the research questions, and the null hypotheses were tested using the t-test at a significance threshold of 0.05. According to the statistics, 51.2% of the respondents in Nigeria meet the minimal teaching standards, while 41.8% do not. Additionally, the study found that although teachers in the Radio Television and Global System Mobile Service trade in Vocational Centers in Gombe State, Nigeria, has some abilities in the profession, much more is still needed. It was suggested that the Gombe State Ministry of Education make sure that instructors appointed to vocational centers are well qualified and hold at least the Nigerian minimum for instructors. Additionally, the government should provide on-the-job training for instructors at vocational centers so they may develop more technical skills for efficient teaching and learning.

Remote-control of multi appliances based latching circuit and DTMF

There are multiple technologies used to remotely control electric appliances like Wi-Fi, Bluetooth, global system for mobile (GSM), and dual-tone multi-frequency (DTMF), but these technologies contain limitations, whether by coverage distance or by the number of devices that are controlled remotely. In this paper, these restrictions were overcome with the use of DTMF and digital latching devices, which doubles the number of remote-controlled electrical appliances compared to other research using the same intended technology DTMF. Using the proposed mechanism in this paper enables the users to effectively control several electric remote devices equal to the standard number of mobile keypad buttons, so in this way, can control 12 devices. This is via the mobile phone by sending commands in the form of analog tones through calling to auto-answer remote control panel phone (RCPP). An interesting feature of this research, each keypad key of the owner mobile (OM) using to control one remote electric device to switch it ON or OFF, so that the first pressing will cause to switch it ON and the second pressing caused to switching it OFF. This method is used instead of using two keypad keys, one for ON and the other for OFF. The proposed idea working is the same as manually switching but here remotely and electronically. This feature is achieved by using a D-latch digital circuit. The work is implemented and tested by using Proteus simulation program.
