Comparing FLV and MPEG4 (H.264/AVC) multimedia file format with wireless network parameters

AbstractData security is an important problem in computer technology. This paper discusses security system for audio data. This technology is crucial because the multimedia technology has been improved very fast. One of the common audio format forms is wave audio format. The wave format is an uncompressed file format which is for RIFF specification owned by Microsoft. It is used for saving multimedia file. By using DES algorithm, the wave data could be encrypted for hiding information contained in the data. DES algorithm is chosen in this research because DES algorithm is one of the best symmetrical cryptography algorithms and it has been used world wide. This research is expected to give contribution to the audio security concept, especially for audio data security using wave file format.Keywords : audio security, DES algorithm, wave Omar

T System

Analysis of the electrical properties of the t-system requires knowledge of the geometry of the t-system network. It is now possible to determine the network parameters experimentally by use of high voltage electron microscopy. The t-system was marked with exogenous peroxidase. Conventional methods of electron microscopy were used to fix and embed the sartorius muscle from four frogs. Transverse slices 0.5-1.0 μm thick were viewed at an accelerating voltage of 1000 kV using the JEM-1000 high voltage electron microscope at Boulder, Colorado and prints at x5000 were used for analysis.The length of a t-branch (t) from node to node (Fig. 1a) was measured with a magnifier; at least 150 t-branches around 30 myofibrils were measured from each frog. The mean length of t is 0.90 ± 0.11 μm and the number of branches per myofibril is 5.4 ± 0.2 (mean ± SD, n = 4 frogs).
