An appropriate velocity model from well logs is a key issue in the processing and interpretation of seismic data. In deep borehole located central part Polish Outer Carpathians, sonic measurements were inadequate for purposes due to poor quality data gaps logging. Multiple regression (MR) modified Faust equation proposed log. MR estimated P-wave slowness as dependent variable on basis sets vari...
Service-oriented systems facilitate business workflows to span multiple organizations (e.g., by means of Web services). As a side effect, data may be more easily transferred over organizational boundaries. Thus, privacy issues arise. At the same time, there are personal, business and legal requirements for protecting privacy and IPR and allowing customers to request information about how and by...
This paper is concerned with an improved network model in acoustical application to petroleum logging and seismic exploration. Utilizing acoustic-electric analogue, we report in this paper a newly developed acoustic-logging network model. Important relationships amongst various physical factors are established, i.e. driving-voltage signal, electric-acoustic conversion of source-transducer, acou...
MyHealthAvatar is a European Commission funded project aimed to design a lifetime companion for citizens to collect, track and store lifestyle and health data to promote citizen well-being. MyHealthAvatar collects and aggregates life-logging data from wearable devices and mobile apps by integrating a variety of life-logging resources, such as Fitbit, Moves, Withings, etc. As a lifelong companio...
this study attempted to explore if teaching english collocations through two different modes of awareness-raising and input flooding has any possible differential effect on immediate retention as well as retention in a delayed assessment. it also compared the possible differential effect of teaching english collocations implicitly and explicitly on actively using the items in writing. m...
Horizontal drilling is an important development in the petroleum industry and it relies heavily on guiding the drill bit with the aid of sonic logging, i.e. geosteering. The quality of sonic imaging depends heavily on the effective suppression of borehole waves and enhancement of weak reflection signal. To this end, we propose an approach to image the near-borehole structure using acoustic logg...
