Reduced differential transform method to solve 5 two and three dimensional second order hyperbolic 6 telegraphic equations Q1 7 Abstract In this article, an analytical solution procedure is described for solving two and three dimensional second order hyperbolic telegraph equation Q3 using a reliable semi-analytic method so called the reduced differential transform method (RDTM) subject to the appropriate initial condition. Using this method, it is possible to find an exact solution or a closed approximate solution of a differential equation. Various numerical examples are carried out to check the accuracy, efficiency, and convergence of the described method. The method is a powerful mathematical tool for solving a wide range of problems arising in engineering and sciences.
One-dimensional second-order hyperbolic telegraph equation was formulated using Ohm’s law and solved by a recent and reliable semianalytic method, namely, the reduced differential transform method (RDTM). Using this method, it is possible to find the exact solution or a closed approximate solution of a differential equation. Three numerical examples have been carried out in order to check the effectiveness, the accuracy, and convergence of the method. The RDTM is a powerful mathematical technique for solving wide range of problems arising in science and engineering fields.
In order to discuss the multimedia communications across 4G networks, it is obvious to unfold the key technologies and innovations in 4G. The 4G system will include all the standards that the earlier generations have been using. The figure 1 shows the evolution in the technologies from 1G, 2G, and 3G to 4G in wireless systems. 4G also contain the wireless local area network system to broadband wireless
AbstractThe user demand for high speed multi-media application has been increasing many folds in the recent years. New smart phones are launching in the market. The wireless communication is looking forward for a new generation technology that will match the application demand and resources. This is where the fourth generation (4G) wireless communication is required. 4G wireless communication is expected to provide better speed, high capacity, low cost IP based services. The main objective of the 4G wireless communication is to supersede the current core technology with a single unified technology. More and more advanced interactive multimedia applications are emerging as 4G networks resulting in a rapid development of video coding and communication techniques. This paper deals with the current scenario and the future prospects of the 4G system in addition with the challenges it is going to witness.
This paper concerns with the modelling of a micro strip antenna with strip line feeding technique formulated using Ohm's law. A partial differential equation is obtained from the model which is solved using ''Reduced Differential Transformation Method (RDTM)". A couple of numerical examples are considered to check the accuracy, efficiency and convergence of the method. The present method is a very powerful mathematical tool for solving wide range of problems arising in circuit theory, RF field, and science and communication system fields.
