Children's Activities

Parents' concerns in terms of monitoring the presence and monitoring of children's activities become one of the problems that are often faced. Training children to prepare themselves to face this sometimes dangerous world, first develop a sense of security in themselves. The objectives of this research are to generate a system or application to track the whereabouts of children through smartphones that can be used by both parents of the child and to design devices that can be used practically and children can be traced to the presence of wireless media by their parents. Improved supervision of children is needed without reducing the freedom of children to learn and explore their environment. One alternative that allows tracking the presence, location, and accuracy is quite good is to use a Geo Positioning System (GPS). This GPS is packaged in a flexible form so that it can help make it easier for parents to supervise their children in the range of areas that are still accessible to them and find the child's position when separated from their parents. The system can send the location information of children who are lost or lost on smartphone applications used by parents.

This paper presents the use of intelligent agent technology, cellular-assisted Global Positioning System (GPS) and data mining for positioning purpose. Due to overlapping coverage areas of cell towers, conventional cell-based positioning techniques have been reported to be inaccurate. Current cell-assisted GPS positioning setup with high accuracy is costly as it requires huge investments on hardware deployments. A new solution of using intelligent agent technology was proposed by the authors for an economical and satisfactory cell-assisted GPS positioning system. Location information in the form of cell identity (ID) and GPS coordinates pairs can be acquired via devices such as smart phones and GPS trackers. The cell ID-GPS coordinates pairs are then grouped by each individual cell ID. An intelligent agent equipped with data mining capabilities is then deployed to computer the optimal GPS coordinates of the cell ID to provide more precise location information. The proposed solution was evaluated via a prototype system. The system was built to collect raw data of cell-ID and GPS coordinate pairs from trackers and mobile phone applications. Using the reference GPS coordinate that was calculated by taking the mean of longitude and mean of latitude for all the GPS coordinates clustered in the same group, the geographical distance between each GPS coordinate and the reference GPS coordinate in the same group was computed to evaluate the performance of the proposed solution.. Experimental results showed that the proposed solution based on intelligent agent equipped with data mining capability helped in improving the prediction of location with sub-kilometer accuracy, in contract to the conventional cell-assisted GPS positioning system which have low accuracy with distance rate various in kilometers.

Time Information

Global Positioning System（GPS）is able to identify real-time information of moving objects quickly and efficiently, such as longitude, latitude, altitude, time and so on. So it has to give the positioning and navigation of objects. This research uses GPS9540 receiver module to receive satellite signals. The time information and location information of this kind of GPS receiver module is GPRMC statement of NMEA-0183 standard format. We use AT89C51 Single Chip Microcomputer (SCM) of ATMEL Corporation as the core controller, and use the serial port of SCM to receive the time information and location information of GPS receiver module. We adjust the time difference information of the GPS receiver module, and finally display acquired location and time information through the liquid crystal display module (LCD). Actual operating results show that the system can decode GPS location information and time information correctly, and positioning information and time information is displayed on the LCD correctly. The system has good reliability and practicality, and it can be used for object location and navigation. This research first introduces the applications and theory of GPS as well as the extraction methods of GPS module output data. Then we introduce the system hardware block diagram and schematic, as well as system software flow chart and software programming, thus we achieve the key technology research of the GPS positioning system.

The main objective of our project is to provide security for human beings especially woman and children with a help of an advanced electronics. As most of the women are subjected to unethical physical harassment when they are alone in public areas, in case they will be provided with an equipment fitted inside the shoes which is not visible to others, the equipment consists of GPS (Global Positioning System) and GSM module by which the geographical location can be tracked and can be sent. In the case of any emergency conditions, the button is pressed and the microcontroller sends latitude and longitude information to authorized persons through GSM. Then the location information is tracked and the information can be sent to police and family members so that they can be rescued in proper time. At the same time, they will be provided a high voltage generating device embedded within the system can be used to generate electric shock to temporarily paralyse the criminals in critical situations. The device is portable and hence can be taken anywhere we travel. It is economical and simple to use. So, it can be effective in saving many people (not merely women) from criminal attacks, sexual harassments and can be used as legal evidence of crime.

The Relationship

BACKGROUND Global seasonal influenza-associated respiratory excess mortality rates have been estimated at 4-8.8 per 100,000 individuals, and this is one of the major issues in public health. Designing efficient containment strategies for highly contagious diseases like influenza has been a subject of very considerable interest recently. Infectious disease epidemic tracking and forecasting have recently been attempted using data based on mobile phone global positioning system (GPS) location information. Tracking and forecasting local influenza spread may contribute to the control of influenza epidemics in an early stage. OBJECTIVE The objectives of this research were to analyze population flow using GPS location data based on the methods proposed by Iwata and Shimizu (2019), and to evaluate influenza infection pathways by determining the relationship between population flow and the number of drugs sold at pharmacies. METHODS Methods proposed by Iwata and Shimizu were applied for all 25 cells to estimate population flow. They proposed a neural collective graphical model (NCGM), which uses a neural network to incorporate the spatiotemporal dependency issue and reduce the estimated parameter. RESULTS The prescription peaks in cells 12 and 14, which had high population flows with cell 13, showed a high correlation with a delay of one to two days. The incubation period is one to four days (average two days) in seasonal influenza. One feature around cell 6 is the low number of prescriptions for anti-influenza drugs. The influenza infection may not have spread to cell 6 due to the low population flow from cells 12 and 13 with high prescriptions. Another feature is the observation of transmission of infection by a small number of influenza patients. In cells 5 and 6 where high population flows were suspected, there was a high cross-correlation value of prescription numbers with a seven-day time-lag. The time-lag is longer than the time-lag observed around cell 13 above. It was observed that not much population flows from cell 19 to the outside area on weekdays. This observation may have been due to geographical features and undeveloped transportation networks. The number of prescriptions for anti-influenza drugs in cell 19 remained low during the observation period. CONCLUSIONS This study conducted population flow estimation analyses during commuting times, based on region-specific GPS location data in four Prefectures in the Kansai region of Japan using methods proposed by Iwata and Shimizu. Furthermore, detailed comparative analyses of the relationship between estimated results of population flow and anti-influenza drug prescription data from pharmacies were conducted. It was found that influenza did not spread to areas with undeveloped traffic networks, and the peak number of drug prescriptions arrived with a time lag of several days in areas with a high amount of area-to-area movement due to commuting.

Marine mines are one of the supporters in securing the marine region of NKRI. In relation to marine mines, the Navy has mapped mines to the territorial waters. The importance of mine site mapping information aims to prevent landmines from being a feeding weapon for the NAVY's Alutsista. In realizing a mine-site mapping and location system that can provide geo-location information for mines using Arduino devices. Build your exercise Smart mine positioning using Global Positioning System (GPS) Neo-M6. A study in providing latitude and longitude location information is packaged using a GPS module that is connected to the Arduino processing device to obtain the location coordinates of the latitude and longitude mines. Test results of GPS-based location tracking devices are obtained by the results of location data in latitude and longitude formats. Smart Mine location identification, can be applied using GPS based on the results of the design and creation of the system that has been done. Location displacement speed calculations can be obtained by calculating the starting location with the updated location in a time span and converting to a unit of distance. Based on the results of the speed test can be obtained even if the device's location position is unchanged, this is due to the GPS data always changing due to the level of position accuracy obtained from satellites. The use of the Neo-M6 GPS can be applied to the latitude and longitude location identification systems acquired a relatively small error value with an average satellite number obtained by as much as 8 satellites. The use of the Neo-M6 GPS, to get GPS data from satellites is a long time, the problem of GPS gets satellite data due to the less supportive weather conditions.
