Design engineering of an embedded system is a lot more complex and with greater security risk than a desktop and web application, as it involves several electronic components, micro controllers, external PCB boards and miscellaneous advanced devices, to be attached, used and properly communicated. Today, embedded systems are widely used for miscellaneous purposes in different fields of life, the goal of this research Read More

Alignment between Information Systems/ Technology (IS/IT) and a company's business strategies has been widely discussed in the literature and remains a priority issue for the areas of business and technology. The issue involves questions of Information System Planning, Information Technology Governance, Investment in Technology and the important decisions taken in this context. Several studies and methodologies Read More

Accuracy of any software release to the market depends on how efficiently it has been debugged. Debugging is a systematic procedure, used to identify and figure out the cause of defects or any anomaly that the software has and make the software behave as expected. The issues generated by the customer of any company are logged into a database, wherein issues are picked up selected, solved and reverted bac Read More

Differential Evolution (DE) is a population-based stochastic global optimization technique proposed by Storn and Price in the middle '90s. Its major advantages are the simplicity, robustness and convergence speed. These characteristics have made differential evolution method popular in diverse areas of science and engineering. This paper provides an overview of state-of-the-art research related to the application of DE a Read More

Multimedia communication has gained an increasing interest in the last decade. The design of services and distributed multimedia applications imposes a number of Quality of Service (QoS) requirements. In particular, the processing and delivery of multimedia content are not independent and their interaction has a major impact on the QoS aspects. Recently, tracing watermarking has been introduced as a blind method for Read More

Cognitive Radio (CR) has been recently proposed as a possible solution to the problem of spectrum scarcity in wireless systems. In a cognitive radio network the (unlicensed) secondary users can access the unused frequency bands assigned to (licensed) primary users, on a non-interfering basis. Spectrum sensing is the fundamental functionality of CR systems that allows secondary users to autonomously identify the unused frequ Read More

Conventional fixed allocation production and allocation injection method has the defects of uneven water flooding, injection-production loss of constant, which can affect water flooding development efficiency. Therefore, we put forward a real-time dynamic optimization water injection method for the different development time and different injection wells with different injection allocation systems. This method converts Read More
