Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Observer is a PHP/MySQL-based Network Monitoring System (NMS) which collects data from devices using SNMP and presents it via a web interface. It makes heavy use of the RRDtool (written by Tobi Oetiker) package. Observer has a number of simple core design goals driving its development: minimum interaction, maximum automation and maximum accessibility of information.
This book has come up with a solution of the present scenario. Smart solutions for under water pollution monitoring are gaining importance with advancement in communication technology. Underwater pollution mainly arising in oceanic areas. Underwater pollution causes acidification, toxins, etc. The proposed model presents a detailed overview of recent works carried out in the field of under water quality pollution monitoring. Also, a power efficient, simpler solution for under water pollution monitoring based on Internet of Things technology is presented. The model developed is used for testing water samples and the data uploaded over the Internet are analysed. The system also provides an alert to a remote user, when there is a deviation of water pollution parameters from the pre-defined set of standard values. Tools used are Embedded C and PHP design as software tool and Embedded Controller, IoT Modem, color sensor, Turbidity Sensor, Conductivity Sensor, Temperature Sensor, PH Sensor as hardware tool.
Repeat photography is an efficient, effective and useful method to identify trends of changes in the landscapes. It was used to illustrate long-term changes occurring in the landscapes. In the Northeast of Portugal, landscapes changes is currently driven mostly by agriculture abandonment and agriculture and energy policy. However, there is a need to monitoring changes in the region using a multitemporal and multiscale approach. This project aimed to establish an online repository of oblique digital photography from the region to be used to register the condition of the landscape as recorded in historical and contemporary photography over time as well as to support qualitative and quantitative assessment of change in the landscape using repeat photography techniques and methods. It involved the development of a relational database and a series of web-based services using PHP: Hypertext Preprocessor language, and the development of an interface, with Joomla, of pictures uploading and downloading by users. The repository will make possible to upload, store, search by location, theme, or date, display, and download pictures for Northeastern Portugal.
Monitoring appliances and other home and office electronics remotely over the Internet is no longer a futuristic dream. Though not yet pervasive, Internet connected systems for homes and businesses are on the market and evolving quickly. As the networking technologies are developing rapidly, more users want to control their home appliances from outside the home. In this book, proposed system lets you monitor your home from any location using an internet. It provides Two Subsystems:Controlling devices over the internet using IP protocol and devices controlled through a mobile application using GPRS protocol. The system enables the user to check, and if needed, change the current status of the Appliance at the same time or at a specified time in the future via a user interface device.The design of this system is based on an embedded controller which is connected to a PC-based home Web server via RS232 serial port. The software of the system is based on the combination of Java 1.6, J2me and PHP 5.0. The system is scalable and allows additional appliances to be added to it with no major change to its core. Other than Home Automation this technology has a wide range of applications.
This project is based on the development of attendance monitoring system, called mobile student attendance monitor. This project is motivated for the reason that the student s attendance record is the most important element which can reflect their academic achievement in the institutions. Mostly, the attendance register is circulated in the lecture rooms by the lecturers. This procedure is time taking method and unsuitable for huge number of students in a big lecture hall. Aim of the project is to develop an efficient, user friendly and effective mobile attendance system that provides an alternative solution to manual attendance in the educational institutions. This prototype system has been built using different technologies like as PHP, My SQL and VB.NET to deal the students attendances by using RFID reader. As, most of the academic institutions provide their students and staffs, ID cards with RFID tags on them. These cards are also known as smart cards . This project is designed to collect and manage student attendance through this technology which works on the verification of the students ID and recording their time of entrance and exit in the lecture halls.
In this book, a developed and implemented VSAT monitoring system has been illustrated, which consists of a client program that runs on the host PC (Linux Fedora core3), and a server program that runs on the targeted VSAT router, the iDirect 3000 series - with ARM (Advanced RISC Machine) processor. Both programs are Linux applications implemented in C/C++ using GCC (GNU Compiler Collection) and cross compiler. The cross compiler was built in the host to after-testing a compatible combination of glibc (GNU C library), binutils (binary utilities), kernel version and GCC itself. The server program monitors the bandwidth usage, keeps a history of (download and upload) rates and modem activities such as BER (Bit Error Rate), memory, disk usage, and the uptime. It sends the monitored data via TPC/IP network using secure shell protocol (SSH) and secure copy (SCP) to an Apache web server. The web server on the host displays the results as charts and numbers using hypertext preprocessor (PHP) to the network administrator.

Developing a new web application should not mean reinventing the wheel. Thats why a framework is an essential item in your development toolbox. It helps you respect coding standards; write bulletproof, maintainable code; and focus on business rules rather than waste time on repetitive tasks. This book introduces you to symfony, the leading framework for PHP developers, showing you how to wield its many features to develop web applications faster and more efficiently, even if you only know a bit of PHP. In The Definitive Guide to symfony, you will learn about the Model-View-Controller architecture and the crucial role it plays in making frameworks like symfony possible. The book also covers framework installation and configuration, and shows you how to build pages, deal with templates, manage requests and sessions, and communicate with databases and servers. You will see how symfony can make your life easier by effectively managing form data, enhancing the user experience with Ajax, internationalizing applications for a global audience, and using smart URLs. Authors François Zaninotto and Fabien Potencier put a strong emphasis on the tools that symfony provides for professional environments, showing you how to take advantage of unit tests, scaffolding, plug-ins, the command line, and extensible configuration. And since frameworks often raise performance-related debate, this book will give you many tips and techniques for monitoring and improving your applications performance, from caching to expert configuration tweaks. Always keen to offer practical instruction, the authors include lots of code examples, expert tips, best practices, and illustrations throughout this book, with the goal of providing a resource that satisfies the educational needs of symfony's rapidly growing user community.
