Pulse arrival time measurement with coffee provocation

This study investigated the effect of coffee intake in pulse arrival time (PAT) and pulse wave velocity (PWV) measured with electrocardiogram (ECG) from arms and photoplethysmogram (PPG) from fingertip. In addition, correlation of PWV with blood pressure (BP) is analyzed. 30 healthy participants were recruited to two measurement sessions, one ...

Pulse arrival time (PAT) measurement based on arm ECG and finger PPG signals - comparison of PPG feature detection methods for PAT calculation

In this study, pulse arrival time (PAT) was measured using a simple measurement setup consisting of arm electrocardiogram (ECG) and finger photoplethysmogram (PPG). Four methods to calculate PAT from the measured signals were evaluated. PAT was calculated as the time delay between ECG R peak and one of the following ...

Statistical fingerprint-based intrusion detection system (SF-IDS)

  • Marchese M.
  • Mariconti E.
  • Naqash T.
  • Zappatore S.

Intrusion detection systems (IDS) are systems aimed at analyzing and detecting security problems. The IDS may be structured into misuse and anomaly detection. The former are often signature/rule IDS that detect malicious software by inspecting the content of packets or files looking for a ``signature{''} labeling malware. They are often ...

Outdoor-indoor angular power spectrum prediction

  • Chizhik D.
  • Valenzuela R.

Theory of normal mode propagation in a LOS street scenario is extended to include propagation into buildings through coupling to a diffuse indoor field. Previous work reported the approach led to close agreement with signal strength measurements. Here it is found that the method reproduces signal directions for direct and ...

Low-frequency illumination by an E wave of infinitely long, parallel, perfect conductors

  • De Smedt R.

The low-frequency illumination by an E wave of one or more perfectly conducting cylinders of arbitrary shape is studied. The induced current, the radiation pattern and the scattering cross section exhibit a frequency dependent logarithmic and the complete, frequency independent part in their low frequency behavior. They can be derived ...

This paper establishes the global well-posedness of the nonlinear Fokker-Planck equation for a noisy version of the Hegselmann-Krause model. The equation captures the mean-field behavior of a classic multi agent system for opinion dyrignics. We prove the global existence, uniqueness, nonnegativity and regularity of the weak solution. We also exhibit ...
