Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Project Report from the year 2011 in the subject Computer Science - Applied, Coventry University (M.S. Ramaiah School of Advanced Studies), course: M. Sc. [Engg] in Real Time Embedded Systems, language: English, abstract: Multimedia applications have an increasing importance in many areas. There is a growing need to store and transmit high quality video for applications where common coding schemes do not yield enough quality. An example of this is Telemedicine system is best example of Applied Medical Informatics. Several physiologic data, Digital images and video can be transmitted more rapidly and easily than conventional images and videos. In telemedicine expert physicians in tertiary care centres can view a digital image, videos and advice local physicians on the best plan of care without having to move the patient many miles away.Telemedicine will be implemented using the TCP client-server model. The clientserver model was originally developed to allow more users to share access to database applications. The data must be secure, when the data is transmitted from server to client, security must ensure that data will not be damaged by attackers and protects against danger, loss, and criminals. Even if someone tries to hack the data content of file should not be revealed to the attacker. So it is necessary to encrypt the data before transmitting the fileusing encryption methods. The encryption method used in server and client model is XOR or AES (advanced encryption standard) or Rijndael algorithm which is used to encrypt and decrypt the x-ray images of patients, drug prescriptions.The Rijndael algorithm allows encrypt video at high quality while achieving great encryption. This property makes the Rijndael algorithm a good option for building a video encryption able to obtain better performance than other more general purpose algorithms such as XOR or AES algorithm. One of the main problems when working with the video sequence is the huge datasets that have to be dealt with. Therefore, memory accesses slowdown the encryption execution. Performance is one of the main concerns of modern systems; thereforeProfiling and tracing tools is used to determine which parts of a program to optimize for speed or memory usage. A general rule of thumb is that 90% of a program's time is spent in just 10% of the code. Profiling enables you to determine which 10% of the code. Theparallelization of code using multithreading concept is required to reduce execution time on the processer and speed up the application. The method of measuring performance is to arrive at the speed of execution, later, measure the execution on a single core and multi-core processor.

Taschenbuch. Zustand: Neu. Neuware -Remote Access of process control devices deals with devices with very limited computing resources with high cost sensitivity such as light switches, dish washers, washing machines, thermostats, dimmers and motion sensors, to name a few. Control devices are practically everywhere around us. Remote Access of Process Control devices is an embedded system project using which we can control the operation of any process device from a computer which can be situated anywhere, provided the client and the server, which is connected to the process device are in a network. The project aims to automate the control of these process control devices, for a process control device to be controlled by the computer, which is called the client, the process control device should be connected to the web-server board, which is called the ¿server¿, and the client and the server should be connected in a network, such as a LAN, WAN or the Internet. The client is provided with a user interface, wherein he/she is given the facility to turn on or off a device. So, one can control any home appliances or industrial machines from any part of the world.Books on Demand GmbH, Überseering 33, 22297 Hamburg 88 pp. Englisch.
