TL;DR: The CNNs were applied to a Music Information Retrieval (MIR), in particular to musical genre recognition, and results achieved were close to the state-of-the-art.
Abstract: Applications of Convolutional Neural Networks ( CNNs ) to various problems have been the subject of a number of recent studiesranging from image classification and object detection to scene parsing, segmentation 3D volumetric images and action recognition in videos. In this study, the CNNs were applied to a Music Information Retrieval (MIR), in particular to musical genre recognition. The model was trained on ILSVRC-2012 (more than 1 million natural images) to perform image classification and was reused to perform genre classification using spectrograms images. Harmonic and percussion separation was applied, because it is characteristic formusical genre. At final stage, the evaluation of various strategies of merging Support Vector Machines (SVMs) was performed on well known in MIR community - GTZAN dataset. Even though, the model was trained on natural images, the results achieved in this studywere close to the state-of-the-art.

TL;DR: The main focus is the reconstruction of the signal using a general purpose receiver, not dedicated to digital television signal reception, and the performance of the proposed method is verified on simulated and real-life signals.
Abstract: In the paper the problem of decoding of digital television signal and its reconstruction for the purpose of using it in passive radar is presented. The main focus is the reconstruction of the signal using a general purpose receiver, not dedicated to digital television signal reception. The performance of the proposed method is verified on simulated and real-life signals. Keywords—Passive radar, passive coherent location, DVB-T.

TL;DR: The experimental results of the test showed that the dilation process to some extent can increase the payload of 18.65% and the average bpp is 1.42 while maintaining the imperceptibilty quality of stego image.
Abstract: This research proposes a method to enhance the payload message by embedding messages on the dilated edge areas by the Least Significant Bit (LSB) method. To add security aspects to messages, messages are not embedded directly on the LSB but encrypted with XOR operations with Most Significant Bit (MSB). The experimental results of the test in this study showed that the dilation process to some extent can increase the payload of 18.65% and the average bpp is 1.42 while maintaining the imperceptibilty quality of stego image with an average PSNR value of about 47 dB, SSIM is 0.9977 and MSE is 1.13.

TL;DR: A review of today’s understanding of the ultimately broadband photonic Internet is presented and it is expected that photonics (with biochemistry, electronics and mechatronics) may build psychological and physiological interface for humans to the future global network.
Abstract: A review of our today’s understanding of the ultimately broadband photonic Internet is presented. A simple calculation is presented showing the estimate of the throughput of the core photonic network branches. Optoelectronic components, circuits, systems and signals, together with analogous electronic entities and common software layers, are building blocks of the contemporary Internet. Participation of photonics in development of the physical layer in the future Internet will probably increase. The photonics leads now to a better usage of the available bandwidth (increase of the spectral efficiency measured in Bit/s/Hz), increase in the transmission rate (from Gbps, via Tbps up to probably Pbps), increase in the transmission distance without signal regeneration (in distortion compensated active optical cables), increase in energy/power efficiency measured in W/Gbps, etc. Photonics may lead, in the future, to fully transparent optical networks and, thus, to essential increase in bandwidth and network reliability. It is expected that photonics (with biochemistry, electronics and mechatronics) may build psychological and physiological interface for humans to the future global network. The following optical signal multiplexing methods were considered, which are possible without O/E/O conversion: TDM-OTDM, FDM-CO-OFDM, OCDM-OCDMA, WDM-DWDM. The Polish perspective closes the review. Keywords—Optical networks, Internet, global network, photonic Internet, future Internet, optoelectronic networks.
