Using a mathematical procedure, we determine appropriate sampling rates for logging heart rate, at a variety of exercise intensities. The mathematical procedure involves correlating exercise and heart rate data to determine a dynamical mathematical model, from which the frequency response of the relationship between exercise intensity and heart rate can be determined. The sampling rate is then ...
A unified view of the area of sparse signal processing is presented in tutorial form by bringing together various fields in which the property of sparsity has been successfully exploited. For each of these fields, various algorithms and techniques, which have been developed to leverage sparsity, are described succinctly. The common potential benefits of significant reduction in sampling rate an...
The rapid-growth of smartphones with embedded navigation systems such as GPS modules provides new ways of monitoring traffic. These devices can register and send a great amount of traffic related data, which can be used for traffic state estimation. In such a case, the amount of data collected depends on two variables: the penetration rate of devices in traffic flow (P) and their data sampling ...
The multi-rate phenomenon of video unusual event is one of the factors to reduce the detection accuracy of video unusual event. Based on the infinite state Hidden Markov Model (iHMM), a multi-granularity detection algorithm for video unusual event is proposed. This algorithm first effectively extracts the feature sequence from the original data through subspace projection technique. Then the fe...
A number of modern measurement instruments employed in different application fields consist of an analogue front-end, a data acquisition section, and a processing section. A key role is played by the data acquisition section, which is mandated to the digitization of the input signal, according to a specific sample rate (Corcoran, 1999). The choice of the sample rate is connected to the optimal ...
Background: This study aimed to assess the relationship between meal frequency with mental distress and violent behavior among a nationally representative sample of Iranian children and adolescents. Materials and Methods: The participants of this national study were 14,880 Iranian students with 6 to 18 years of age. They were selected from urban and rural regions of Iran by multi-stage cluster ...
The structure of the Open Sound Control (OSC) content format is introduced with historical context. The needs for temporal synchronization and dynamic range of audio control data are described in terms of accuracy, precision, bit-depth, bit-rate, and sampling frequency. Specific details are given for the case of instrumental gesture control, spatial audio control and synthesis algorithm control...
For the extremely high sampling rate and high resolution required for multi-Gigabit orthogonal frequency division multiplexing (OFDM) communication systems, timeinterleaved analog-to-digital converters (ADCs) are being considered. However, in practice, mismatches such as offset mismatch, gain mismatch and timing mismatch occur between the parallel sub-ADCs. This paper theoretically analyzes the...
