abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...
The attenuation values obtained in the lab are usually larger than those measured in the field. To understand this inconsistency, I propose to model attenuation from rock properties and reflection seismic data, and then compare their results. A gas well is used here for providing the rock properties and seismic properties. The preliminary results show that scaling is one of the factors that low...
Background: Human growth is dependent upon social interactions, notably essential during the middle childhood years (ages 5-10). Although some children develop differently than others, all experience the same types of mental processes through which, due to a variety of factors, they may become typically achieving, or stunted in their development. Language is a key component of being human. Comm...
one of the most important goals for increasing recognition and treatment revenue is transmitting vital data to medical care team, more quickly. nowadays, use of new technologies for transmitting data will deploy more and more daily. in this article, for transmitting electrocardiogram, first we code the signal into a suite of codes, then we will use bluetooth technology to transmit data from off...
chapter one is devoted to a moderate discussion on preliminaries, according to our requirements. chapter two which is based on our work in (24) is devoted introducting weighted semigroups (s, w), and studying some famous function spaces on them, especially the relations between go (s, w) and other function speces are invesigated. in fact this chapter is a complement to (32). one of the main fea...
Seismic acquisition and monitoring system can collect, store, analyze and dispose the rock burst seismic waves or the vibration of other objects. This paper utilizes single chip computer technology, virtual instrument technology, sensor technology, database management technology, wavelet analysis technology, combining the real condition of the mine microseismic signal to establish a set of mine...
In some cases, the variations in the subsurface rock property with time can be observed during fluid flow process because of changes in stress, pore pressure, temperature, degree of consolidation, and fluid content. Detecting these changes via their influence on the in situ elastic properties serves as the basis for timelapse monitoring. Acquisition and processing of high-fidelity time-lapse se...
so far a number of works on the heat flux anomalies of the earth surface based on the satellite images and underground water as seismic precursors have been carried out. in this paper the soil temperature data at 1m depth (deep enough to filter temperature variation due to high frequency meteorological forcings) has been considered to see if there are connections between earthquakes in bam and ...
faults/fractures detection is an essential step of the full field study in hydrocarbon reservoir. definition of exact location of these structural events is a critical step to optimize location of the development wells. despite of the fast development of the geo science technology and oil industry in recent years, detection of the small geological events such as faults and fractures in some of ...
New high resolution seismic data (Subbottom Chirp) coupled to high resolution Multibeam bathymetry collected in the frame of the Stromboli geophysical experiment aimed at recording active seismic data and tomography of the Stromboli Island are here presented. The Stromboli geophysical experiment has been already carried out based on onshore and offshore data acquisition in order to investigate ...
