Quantitative determination of uncertainties in seismic refraction prospecting
We present a model of the propagation of refracted seismic waves in planar (horizontal or dipping) layered structures in which we quantify the errors from various sources. The model, called the (mixed) variance component model, separates the errors originating on the surface from those due to inhomogeneities of subsurface layers. The model starts with the assumption of homogeneous (constant-vel...
متن کاملThe Amplitudes of Waves to Be Expected in Seismic Prospecting
A method of calculating the amplitudes of bodily waves in earthquakes is applied to a study of the amplitudes of longitudinal waves produced by an artificial explosion. Formulae are given for calculating the energy of the reflected longitudinal wave arriving at the surface. The percentage of energy reflected at a discontinuity increases rapidly after the angle of incidence exceeds the critical ...

امروزه تصحیح همکلاسی در کلاسهای نگارش یکی از اجزاء لاینفک کلاسهای دانش آموز محور است. تاثیرات مفید تصحیح همکلاسی بر زبان آموزان، معلمان را متقاعد کرده است که علیرغم صرف زمان، انرژی و توان بسیار، از این شیوه ی آموزشی در کلاسهای آموزش نگارش بهره بگیرند. تحقیق حاضر بر آن است تا با مقایسه دو گروه از یادگیرندگان زبان انگلیسی، تاثیر تصحیح همکلاسی را بر توانایی نوشتاری آنها نشان دهد. 122 خانم زبان آمو...
15 صفحه اولProspecting for geothermal energy through satellite based thermal data: Review and the way forward
Geothermal investors need to be confident with the methods and results of exploration programs. Also cutting the upfront cost of geothermal exploration will further encourage investors to consider investment in this emerging clean energy field. Hence, it is of paramount importance to improve prospecting techniques in order to explore where economic concentrations of geothermal energy are to be ...
متن کاملProspecting for (Campaign) Gold
Campaigns and political parties are faced with the immensely important practical challenge of financing their efforts. Raising money is instrumental to all other aims. In recent years, this task has been complicated by the need to enlist ever greater numbers of contributors to raise ever larger sums of money. At the same time, fundraising burdens are eased a bit because contributors flock toget...
