The rhythmic background of a musical piece is usually composed of featured elements that define the musical genre. For each song, such elements form rhythmic patterns, the most repetitive ones defines the rhythm of a specific musical genre and the less frequent ones correspond to fortuitous patterns that comply a transition, diversification, introduction or conclusion function. In this paper, we introduce...
In this paper a new neural network system for composition of melodies is proposed. The Long Short-Term Memory (LSTM) neural network is adopted as the neural network model. We include an independent melody as an additional input in order to provide an inspiration source to the network. This melody is given by a chaotic composition algorithm and works as an inspiration to the network enhancing the subjective...
In this work, an Elman recurrent neural network is used for automatic musical structure composition based on the style of a music previously learned during the training phase. Furthermore, a small fragment of a chaotic melody is added to the input layer of the neural network as an inspiration source to attain a greater variability of melodies. The neural network is trained by using the BPTT (back...
Radio signals based indoor location systems is a hot topic. Even many papers deals with this subject, and some solutions were tested, currently we have no mature commercial implementations. Based on WLAN, RFID, WSN, ZigBee or proprietary solutions, location systems working principles implies the measurement of radio signals. Due to propagation issues in real working conditions, the practical demonstrated...
We present some performance evaluations of two Power Line Ethernet adapter types and several radiated and conducted emissions measurements. The Power Line Communication provides multiple benefits, but there are some disadvantages of connecting through power line network: high noise and voltage disturbances, signal distortion and variance of impedance with time, interferences. The limits for radiated...
Wireless sensors are widely used in applications where small amount of data need to be transmitted over distances not exceeding several tens of meters, with low energy requirements. From the definition, the RSSI is the relative received signal strength in a wireless environment. There is a direct link between the RF power level received by one node and the RSSI indication. We used for the measurements...
Many efforts where made in the last years in order to develop new techniques for mobile objects identification, location and tracking. Radio Frequency Identification (RFID) systems are a possible solution to this problem. There are many different practical implementations of such systems, based on the use of radio waves from low frequencies to high frequencies. In this paper we present a short review...
