As the author could not find a reassuring mathematical and statistical method in the literature for studying the effect of information communication technology on enterprises, the author suggested a new research and analysis method that he also used to study the Hungarian economic sectors. The question of what factors have an effect on their net income is vital for enterprises. At first, the author studied some potential indicators related to economic sectors, then those indicators were compared to the net income of the surveyed enterprises. The resulting data showed that the growing penetration of electronic marketplaces contributed to the change of the net income of enterprises to the greatest extent. Furthermore, among all the potential indicators, it was the only indicator directly influencing the net income of enterprises. With the help of the compound indicator and the financial data of the studied economic sectors, the author made an attempt to find a connection between the development level of ICT and profitability. Profitability and productivity are influenced by a lot of other factors as well. As the effect of the other factors could not be measured, the results – shown in a coordinate system – are not full but informative. The highest increment of specific Gross Value Added was produced by the fields of ‘Manufacturing’, ‘Electricity, gas and water supply’, ‘Transport, storage and communication’ and ‘Financial intermediation’. With the exception of ‘Electricity, gas and water supply’, the other economic sectors belong to the group of underdeveloped branches (below 50 percent). On the other hand, ‘Construction’, ‘Health and social work’ and‘Hotels and restaurants’ can be seen as laggards, so they got into the lower left part of the coordinate system.‘Agriculture, hunting and forestry’ can also be classified as a laggard economic sector, but as the effect of the compound indicator on the increment of Gross Value Added was less significant, it can be found on the uper left part of the coordinate system. Drawing a trend line on the points, it can be made clear that it shows a positive gradient, that is, the higher the usage of ICT devices, the higher improvement can be detected in the specific Gross Value Added.

Geometric design often requires the capability to manipulate flexible objects, including bending, twisting, compressing or stretching parts of the model or its entire geometry. The proposed approach comprises also shape deformations with multiple (real, auxiliary, and virtual) control points and constrained, directional, and anisotropic deformations. It allows a user to edit a given shape interactively and spontaneously.Our approach successfully suggests a sense of rigidity of the lattice, which is difficult in interactive shape editing approaches.Mathematically, the problem being addressed in this research work involves a Free-Form Deformation (FFD) of the features of the affine three dimensional geometry of the image. The algorithms primarily develop are projective geometry techniques, which form the basis for accurate deformation. Furthermore, these algorithms generally assume standardized images, i.e. no prior knowledge of either the shape, or its pose(position and coordinates) with respect to the transformed coordinates. This project aims to develop a general framework for perform mesh deformation and editing in real-time. The prerequisites include C/C++, OpenGL and basic knowledge in differential geometry

Cloud Computing is a most recent and hottest buzzword nowadays, emerges as a key service of the Utility or On-demand computing [1] which builds on decade of research in the ground of computer networking, World Wide Web and software services. It put forwards a service oriented architecture, reduced information technology overhead for the end-user, enormous and huge flexibility and reduced total cost of ownership. Recent attacks on the clouds especially DDoS poses as a potential intimidation and danger to this key technology of the expectations and future. In this paper we are going to present a new Cloud Environment and Architecture and an Entropy based ADS approach to mitigate the DDoS attack which further improves network performance in terms of computation time, QoS and HA under Cloud computing environment SaaS, PaaS, IaaS and IT Foundation are four basic types of Cloud Computing [30, 31, 32].

Advantages of Microstrip patch antennas make them solid candidate for the field of communication in Microwave application. This paper consists of Microstrip patch antennas with complete mathematical calculations, Simulation results and the relevant antenna applications on the operating frequencies. These designed antennas have frequency ranges in Microwave S band, C band and X band. S band cover the frequencies of 2 GHz, 3 GHz and 3.5 GHz. C band cover the frequencies of 8GHz and 9 GHz. These antenna simulations performed by using Ansoft HFSS TM V10.0. Simulation results are presented in terms of Resonant Frequency Return Loss, VSVR, Radiation Pattern and the antenna Gain.Micr ostrip patch antennas have wide range of applications, however here in this paper following applications are presented. WLL, WiMAX, Satellite Communication and Marine Radar Communication (SART).
