Video conferencing is executed connected with video conferencing. Many people refer to it as videoconferencing. This kind of techniques is among the brand-new efficient strategies to transmission today specifically all over region and continents. Video conferencing consists of connection involving two or more teams of individuals in a given setting or even between numerous places along with internet sites from different periods. In general, its major role is actually interaction in between men and women regardless of the distance.
Carbon nanotubes(CNTs) aresomeof most valuable materials that have highest thermal conductivity.The thermal conductivity of individual carbon nanotubes is 2000 Wm −1 K −1 compared with the thermal conductivity 419 Wm −1 K −1 of silver.Therefore, carbon nanotubes have opened a new way for heat dissipation for high power electronic components, such as micro-processor, high brightness LED, etc. In this paper, we present the simulation results on heat dissipation for a high power electronic component using carbon nanotube nanofluids.

Величање окупације Србије 1945-2000 и која још увек траје од стране комуњара (прво уз помоћ "демократа" а сада уз помоћ четника гибаничара) само доказује да људи који не могу критички да погледају прошлост а нарочито своју обесмишљава сваки договор са онима који своју комуњарску пљачку називају "поштеним друштвом"

This paper presents the generation of optical carrier suppressed signal for RoF system. RoF refers to an analog transmission over fiber technology where light is modulated by radio frequency (RF) signal and transmitted over an optical fiber link to wireless access. Both optical carrier suppression and signal modulation are made by using a Dual-Drive Mach-Zehnder modulator (DD-MZM). Suppressed carrier modulation is achieved by biasing at the null point of DD-MZM. Optical carrier suppression improves the performance of RoF system such as link gain and noise figure (NF).In this research, a single RF at 2100 MHz having data rate of a 1 Gbps modulates the 1550.12 nm optical carrier in the DD-MZM. In this paper, the carrier suppression and performances of RoF system are investigated by theory and simulation. The various values of optical carrier suppression ratio can be obtained by adjusting the extinction ratio of the DD-MZM.
In this paper a new scheme is proposed for progressive image transmission over coded Orthogonal Frequency Division Multiplexing (OFDM) system with Low Density Parity Check Coding (LDPC). Trigonometric transforms are used in this scheme for improving the performance of the OFDM systems and reducing the PeakTo- Average Power Ratio (PAPR) of OFDM signal. It improves the error resilience ability and transmission efficiency for progressive image transmission over Additive White Gaussian Noise (A WGN) channel. The Set Partitioning In Hierarchical Trees (SPIHT) algorithm is used for source coding of the images to be transmitted. In the proposed scheme the transmit data sequence of the OFDM signal after Inverse Fast Fourier Transform (lFFT) is grouped into in-phase and in-quadrature components, then each component is transformed using either the Discrete Cosine Transform (DCT) or the Discrete Sine Transform (DST). The simulation results show that adding the DST to the system im
