Most geophysical inverse problems are nonlinear and rely upon numerical forward solvers involving discretization simplified representations of the underlying physics. As a result, modeling errors inevitable. In practice, such model tend to be either completely ignored, which leads biased over-confident inversion results, or only partly taken into account using restrictive Gaussian assumptions. ...
Geophysical methods off er several key advantages over conven onal subsurface measurement approaches, yet their use for hydrologic interpreta on is o en problema c. We developed the theory and concepts of a novel Bayesian approach for high-resolu on soil moisture es ma on using travelme observa ons from crosshole ground-penetrating radar experiments. The recently developed Mul -Try Diff eren al...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...
Geophysical techniques can help to bridge the inherent gap that exists with regard to spatial resolution and coverage for classical hydrological methods. This has led to the emergence of a new and rapidly growing research domain generally referred to as hydrogeophysics. Given the differing sensitivities of various geophysical techniques to hydrologically relevant parameters, their inherent trad...
abstract according to increase in electricity consumption in one hand and power systemsreliability importance in another , fault location detection techniqueshave beenrecentlytaken to consideration. an algorithm based on collected data from both transmission line endsproposed in this thesis. in order to reducecapacitance effects of transmission line, distributed parametersof transmission line...
Anisotropy and attenuation of crosshole channel waves from the Antrim Shale gas play, Michigan Basin
in this thesis, using concepts of wavelets theory some methods of the solving optimal control problems (ocps). governed by time-delay systems is investigated. this thesis contains two parts. first, the method of obtaining of the ocps in time delay systems by linear legendre multiwavelets is presented. the main advantage of the meth...
