MXene-based Lightning Strike Protection Coating In article number 2100803, Vipin Kumar and co-workers investigate MXene as an effective filler to improve the electrical mechanical properties of divinylbenzene (DVB) thermosetting resin. Its performance a lightning strike protection coating for carbon fiber reinforced polymer (CFRP) is evaluated. MXenes-DVB reduces surface damage from 40.61 cm2 (...

Orthogonal Frequency Division Multiplexing system used in number of communication systems. It is a powerful technique that uses an IFFT at the transmitter to modulate a high bit error rate signal onto a number of carriers. But it faced one problem that is inherently inflexible and requires a complex IFFT core. To overcome this problem a new DVB-T system is designed that utilizes the flexible na...

The contribution deals with the utilization of Matlab for simulation and analysis of digital QPSK and M-QAM modulators and demodulators used in DVB (Digital Video Broadcasting) standard. Presented modulators and demodulators are optional modules of simulation system that can evaluate the influence of transmission errors on transmitted digital signal and according visual information. The system ...

The paper discusses methods for robust audio-video broadcast over the digital video broadcasting-handheld (DVB-H) system. DVB-H includes a link-layer forward error correction (FEC) scheme known as multiprotocol encapsulation (MPE) FEC, which provides equal error protection (EEP) to the transmitted media streams. Several approaches for unequal error protection (UEP) have been proposed in the lit...

The paper presents an overview of the main methods used to improve the efficiency of DVB systems, based on multiplexing, through a study on the impact of the multiplexing methods used in DVB, having as a final goal a better usage of the data capacity and the possibility to insert new services into the original DVB Transport Stream. This study revealed that not all DVB providers are using statis...

Contemporary DVB-based digital terrestrial systems (DVB-T, DVB-H) provide an efficient distribution network not only for DTV programs, but also for interactive data services. When combined with an appropriate interaction network (return channel), the DVB platform can act as the downlink in a hybrid asymmetric network, enabling for bidirectional broadband data access, supporting Internet connect...

purpose t1wi (t1 weighted image) was acquired in order to grade bone fusion following the studies by fifa (federation internationale de football associations). research using images other than t1wi has not been reported. the aim of this study is to evaluate the grade of epiphyseal fusion by t2* weighted images (t2*wi) and to investigate new findings on t2*wi as compared with t1wi. methods a tot...
