A detailed study is carried out to investigate the effects of an acoustic logging tool on the propagation characteristics of Stoneley waves in both elastic and porous formations. In an elastic formation, the presence of the tool in the borehole reduces the Stoneley velocity and enhances the Stoneley wave excitation. When intrinsic attenuation due to formation and bore fluid anelasticity is pres...

Blood pressure measurement methods used nowadays have considerable drawbacks, as non-invasive measurements are non-continuous while invasive measurements are confined to in-hospital use. In this paper, we expose our solution of a continuous, non-invasive blood pressure measurement method, using electrocardiogram (ECG) and photopletysmograph (PPG) as a basis of calculation. We present the two ap...

The development of satellite-derived datasets has greatly facilitated large-scale ecological studies, as in situ observations are spatially sparse and expensive undertakings. We tested the efficacy of using satellite sea surface temperature (SST) collected by NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) and local water temperature collected from NOAA buoys and onshore stations t...

A battery, also known as an accumulator, is electrical cell that can reverse electrochemical process with high efficiency. It essential in the use of systems storage devices. has two critical parameters: current and voltage. These parameters affect battery's behavior, which leads to battery usage. As a result, monitoring instrument required monitor voltage while it use. The researchers designed...

Emergence of uniquely addressable embeddable devices has raised the bar on Telematics capabilities. Though the technology itself is not new, its application has been quite limited until now. Sensor based telematics technologies generate volumes of data that are orders of magnitude larger than what operators have dealt with previously. Real-time big data computation capabilities have opened the ...
