The project which we are doing is about “COLLEGE PHONE BOOK”. It is about storing the information or details of each individual student studying in their respective departments, which displays the name of the student, phone number(s) of the each individual student. This will be a very useful concept as it will give the college management or the department head to know the complete information of the student studying in that department. This project is based on the database in which we can store and retrieve all the information regarding students and what all we require.
Database is a structured format. So if we store in the database, we can retrieve that particular information by giving a command directly. There is no process for installing database for mobile-phone applications. Whenever the database is needed, then only the database is created through coding. Here we have the feasibility to give input, change the data and to delete it if we are not in need of it anymore, with the following option in the first screen – COLLEGE PHONEBOOK.
PURPOSE OF THIS PROJECT:
This project is mainly used to decrease the time constrain to find all fun and food zones near to the user location.The main advantage of this application is the user can view all the fun and food zones at one place,now we have so many websites and applications which gives information only about food or fun individually.To overcome this disadvantage we developed an application which gives all the details about both fun and food zones based on user specified location so we Entitled this project as ‘FUN AND FOOD’ it is used to provide all fun and food zones near to location specified by the user.The user can view minimum details of nearest fun and food zones and user can also view the details of respective fun and food service provider.
Parent communication register android applicationBhadra Gowdra
In this new era of Science and Technology, computer is one of the most important components in our life. Works can be done in a better way by the help of computer.
The Main aim of our project is to automate the attendance in the form of Android Mobile Application. Our intention is to establish a good communication between Student Mentor and parent.We have seen over the years that the process of manual attendance is being carried out across almost all educational institutions. The process is not only time consuming but also sometimes yield inefficient results in the false marking and calculation of attendance. We need not maintain pen and paper based attendance registers. Following this thought, we have proposed a Parent communication register android application APP by which we notify parents via SMS OR a call Notification system which is implemented on Android mobile application.This Android application will give the students attendance information and SMS notification feature whereby every parent will be periodically notified regarding his/her child attendance. Our system primarily focuses on building an efficient and user friendly Android mobile application. The application will be installed on the Mentor phone which runs android OS. It intends to provide an interface to the professor who will require a user id and password to carry out the task. Apart from that, the application would support strong user authentication and quick transmission of data.
Imagine a vitamin pill-sized camera that could travel through your body taking pictures, helping diagnose a problem which doctor previously would have found only through surgery.

The Global Positioning System (GPS), originally Navstar GPS,[1][2] is a space-based radionavigation system owned by the United States government and operated by the United States Air Force. It is a global navigation satellite system that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites
2. The control segment consists of worldwide monitor and control stations that maintain the satellites in their proper orbits through occasional command maneuvers, and adjust the satellite clocks. It tracks the GPS satellites, uploads updated navigational data, and maintains health and status of the satellite constellation.
7. 902-928 MHz (spread spectrum) The lower-frequency radios (150-174 MHZ) tend to have more power, due to design and legal issues (not Physics), However, the bandwidth, which determines the amount of data you can transmit, is narrower in these lower ranges (also due to design, not physics). In the nominal 450 MHz and 900 MHz ranges, the bandwidth is wider. This has positive effects both on the amount of data transmitted and on the number of repeaters possible within the radio network. Radio Range To guarantee steady, uninterrupted transmission over the radio, one should be aware of some of the factors that affect the radio's effective range. Antenna Height: raising the radio antenna is the easiest and most effective way to increase range. Antenna design: radiating patterns vary, depending on the antenna design. For best performance, be sure you understand how yoour antenna transmits signals. Cable length and type: radio signals suffer loss in cables, so keep the length to a minimum. If you must use long cables, use low-loss cables. Output power: doubling output power does not double your effective range. Be sure one understands the relationship between power and gain before the best system is decided. Obstructions: Buildings, walls and even the machines can block or interrupt radio transmission. The repeaters should be carefully used to help minimize the effect of obstructions. Grounding The radio antenna may be a target for lightning. To avoid damage, you may wish to ground your reference station antenna. GPS Applications One of the most significant and unique features of the Global Positioning Systems is the fact that the positioning signal is available to users in any position worldwide at any time. With a fully operational GPS system, it can be generated to a large community of likely to grow as there are multiple applications, ranging from surveying, mapping, and navigation to GIS data capture. The GPS will soon be a part of the overall utility of technology. There are countless GPs applications, a few important ones are covered in the following passage. Surveying and Mapping The high precision of GPS carrier phase measurements, together with appropriate adjustment algorithms, provide an adequate tool for a variety of tasks for surveying and mapping. Using DGPs methods, accurate and timely mapping of almost anything can be carried out. The GPS is used to map cut blocks, road alignments, and environmental hazards such as landslides, forest fires, and oil spills. Applications, such as cadastral mapping, needing a high degree of accuracy also can be carried out using high grade GPS receivers. Continuous kinematic techniques can be used for topographic surveys and accurate linear mapping. Navigation Navigation using GPS can save countless hours in the field. Any feature, even if it is under water, can be located up to one hundred meters simply by scaling coordinates from a map, entering waypoints, and going directly to the site. Examples include road intersections, corner posts, plot canters, accident sites, geological formations, and so on. GPS navigation in helicopters, in vehicles, or in a ship can provide an easy means of navigation with substantial savings. Remote Sensing and GIS It is also possible to integrate GPS positioning into remote-sensing methods such as photogrammetry and aerial scanning, magnetometry, and video technology. Using DGPS or kinematic techniques, depending upon the accuracy required, real time or post-processing will provide positions for the sensor which can be projected to the ground, instead of having ground control projected to an image. GPS are becoming very effective tools for GIS data capture. The GIS user community benefits from the use of GPS for locational data capture in various GIS applications. The GPS can easily be linked to a laptop computer in the field, and, with appropriate software, users can also have all their data on a common base with every little distortion. Thus GPS can help in several aspects of construction of accurate and timely GIS databases. Geodesy Geodetic mapping and other control surveys can be carried out effectively using high-grade GPs equipment. Especially when helicopters were used or when the line of sight is not possible, GPS can set new standards of accuracy and productivity. Military The GPS was primarily developed for real time military positioning. Military applications include airborne, marine, and land navigation. Future of GPS Technology Barring significant new complications due to S/A (Selective Availability) from DOD, the GPS industry is likely to continue to develop in the civilian community. There are currently more than 50 manufacturers of GPs receivers, with the trend continuing to be towards smaller, less expensive, and more easily operated devices. While highly accurate, portable (hand-held) receivers are already available, current speculation envisions inexpensive and equally accurate 'wristwatch locators' and navigational guidance systems for automobiles. However, there is one future trend that will be very relevant to the GIS user community, namely, community base stations and regional receive networks, as GPS management and technological innovations that will make GPS surveying easier and more accurate.
