[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 file using 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

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; therefore Profiling 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. The parallelization 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.

Book Description
Presenting encryption algorithms with diverse characteristics, Image Encryption: A Communication Perspective examines image encryption algorithms for the purpose of secure wireless communication. It considers two directions for image encryption: permutation-based approaches and substitution-based approaches. Covering the spectrum of image encryption principles and techniques, the book compares image encryption with permutation- and diffusion-based approaches. It explores number theory-based encryption algorithms such as the Data Encryption Standard, the Advanced Encryption Standard, and the RC6 algorithms. It not only details the strength of various encryption algorithms, but also describes their ability to work within the limitations of wireless communication systems. Since some ciphers were not designed for image encryption, the book explains how to modify these ciphers to work for image encryption. It also provides instruction on how to search for other approaches suitable for this task. To make this work comprehensive, the authors explore communication concepts concentrating on the orthogonal frequency division multiplexing (OFDM) system and present a simplified model for the OFDM communication system with its different implementations. Complete with simulation experiments and MATLAB® codes for most of the simulation experiments, this book will help you gain the understanding required to select the encryption method that best fulfills your application requirements.

Book Description
Why have a book about the relation between requirements and software architecture? Understanding the relation between requirements and architecture is important because the requirements, be they explicit or implicit, represent the function, whereas the architecture determines the form. While changes to a set of requirements may impact on the realization of the architecture, choices made for an architectural solution may impact on requirements, e.g., in terms of revising functional or non-functional requirements that cannot actually be met. Although research in both requirements engineering and software architecture is quite active, it is in their combination that understanding is most needed and actively sought. Presenting the current state of the art is the purpose of this book. The editors have divided the contributions into four parts: Part 1 “Theoretical Underpinnings and Reviews” addresses the issue of requirements change management in architectural design through traceability and reasoning. Part 2 “Tools and Techniques” presents approaches, tools, and techniques for bridging the gap between software requirements and architecture. Part 3 “Industrial Case Studies” then reports industrial experiences, while part 4 on “Emerging Issues” details advanced topics such as synthesizing architecture from requirements or the role of middleware in architecting for non-functional requirements. The final chapter is a conclusions chapter identifying key contributions and outstanding areas for future research and improvement of practice. The book is targeted at academic and industrial researchers in requirements engineering or software architecture. Graduate students specializing in these areas as well as advanced professionals in software development will also benefit from the results and experiences presented in this volume.

Master's Thesis from the year 2013 in the subject Electrotechnology, grade: First Class, , course: Master Of Engineering, language: English, abstract: In today's modern communication industry, antennas are the most important components required to create a communication link. Microstrip antennas are the most suited for aerospace and mobile applications because of their low profile, light weight and low power handling capacity. These antennas can be designed in a variety of shapes in order to obtain enhanced gain and bandwidth for dual band and tri-band operation. This book focus on a detailed study of how to design and simulate a microstrip fed rectangular patch antenna using IE3D software with effect of antenna dimensions length ( L ), width ( W ), relative dielectric constant , substrate thickness (t ) on the radiation parameters of bandwidth and gain. The design parameters of the antenna calculated using the transmission line model. Here antenna operates for tri- band operation, the operating bands are GSM , PCA and UTMS for antenna geometry -I and WLAN and WiMAX for antenna geometry -II. The fractional bandwidths (FB) after simulation obtain under criterion ( S_11
