The Impact Of The Development Of ICT In Several Hungarian Economic Sectors
No full textAs 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 in the upper 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

A Scalable Detection Technique for Real-time Transport Protocol (RTP) Flooding Attacks in VoIP Network
No full textAbstractVoice over Internet Protocol (VoIP) has become widely uses RTP as its media protocol that delivers multimedia sessions over IP based network. RTP is the hub of media flooding attacks that causes inconsistency of media transmitted which degrading Quality of Service (QoS) and unnecessary resource consumption in servers. Thus, the motto of the paper is revolved around detection of RTP flooding attacks. In this paper, Packet Inspection using Statistical (PIS) technique is proposed that detects RTP flooding attacks. The experimental results show that the proposed PIS technique has a detection rate of more than 98% with False Positive (FP) of less than 0.1%
Video over Internet: Analysis using SIP, RTP/RTCP Protocols
No full textThe goal of this project is to analyze video calls over the Internet Protocol (Video over IP) using a simulated IMS environment (IMS-in-a-box). The thesis presents an overview of IMS, its purpose and how it has evolved. The thesis also attempts to give the reader a full and comprehensible understanding of what the IMS is all about, its purpose and why it came into existence. The thesis considers a number of different video call case scenarios that are most likely to be encountered when making video calls over the Internet using the Internet protocol. This analysis focuses mainly on the SIP, RTP/RTCP protocols and how these three protocols are related and synchronized in order to actually know what is happening during the course of call set up and media exchange between the various end callers involved. The report looks into aspects of bandwidth consumption by the exchanged media (RTP and RTCP), jitter and its variation over the duration of the calls and the cooperation between the control plane and the user plane in order for a smooth call set up, media exchange and release of network resources. The thesis focuses on the areas of interest mentioned above, as these protocols have been identified as being of high significance in media transfer during video calls over IP.TelecommunicationsElectrical EngineeringElectrical Engineering, Mathematics and Computer Scienc

Tanami MainNS - TMI RTP 1VD grid (AWAGS)
No full textMaintenance and Update Frequency: notPlannedStatement: This Tanami MainNS - TMI RTP 1VD grid (AWAGS) is the first vertical derivative grid of an airborne-derived Total Magnetic Intensity (TMI) Reduced to the Pole (RTP) grid for the NTGS Tanami NS Detailed Airborne Magnetic Radiometric and Digital Elevation Survey, NT, 2018 survey. The survey was acquired under the project No. 1312 for the geological survey of NT. A total of 145230 line-kilometres of data at a line spacing of 200m were acquired to produce the TMI grid. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey. A first vertical derivative was calculated by applying a fast Fourier transform (FFT) process to the TMI RTP grid of the NTGS Tanami NS Detailed Airborne Magnetic Radiometric and Digital Elevation Survey, NT, 2018 survey to produce this grid. This grid was calculated using an algorithm from the INTREPID Geophysics software package. The image shows the magnetic response of subsurface features with contrasting magnetic susceptibilities. The image can also be used to locate structural features such as dykes. Details of the specifications of individual airborne surveys can be found in the Fourteenth Edition of the Index of Airborne Geophysical Surveys (Percival, 2014).

Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. .<br/> This Tanami MainNS - TMI RTP 1VD grid (AWAGS) is the first vertical derivative of the TMI RTP grid of the NTGS Tanami NS Detailed Airborne Magnetic Radiometric and Digital Elevation Survey, NT, 2018 survey.<br/>This grid has a cell size of 0.00036 degrees (approximately 40m) , and given in units of nT per metre (nT/m).
