one of the most practical routine tests for convergence of a positive series makes use of the ratio test. if this test fails, we can use rabbe's test. when rabbe's test fails the next sharper criteria which may sometimes be used is the bertrand's test. if this test fails, we can use a generalization of bertrand's test and such tests can be continued innitely. for simplicity...

Foundation of buildings in soft soil such as quaternary clay is often associated with difficult compaction, settlement, non-uniform and/or excessive deformation, and unsatisfactory shear resistance. The present study aims to assess the possibility using recycled fines from construction demolition waste, mechanically treated gypsum waste concrete powder (WCP), instead ordinary binders or industr...

The aim of this work was to investigate a wide range grain sizes sand in the pre-yield regime during compression through combined study ultrasound (US) wave speed and acoustic emission (AE). specific performed using modified oedometer uniaxial experimental set-ups. studied samples were natural dune (poorly graded on poorly (SP) index) as well its three extracted fractions follows: 2.36–0.6 mm, ...

The Callovo-Oxfordian (COx) claystone has been considered as a possible host rock for deep geological repository of high-level radioactive waste in France. When constructing the repository, it is unavoidable to generate fractured zone vicinity excavated walls. In assessment performance, important investigate role fractures on swelling capacity COx and further characterize evolution. this study,...

Abstract Particle breakage and the corresponding change of morphology are two key factors governing mechanical behavior calcareous sands in offshore geotechnical engineering constructions. To reveal characteristics these factors, oedometer tests on have been performed this study. The materials were sampled from South China Sea with a homogenous composition but different particle size ranges rel...

Pengujian dan diagnosis non-destruktif sangat populer, karena efektif untuk investigasi atau inspeksi bawah permukaan dapat melakukan pemantauan, prediksi, pengelolaan dengan lebih tepat seperti halnya pemantauan kualitas kondisi jalan jembatan, hingga prediksi kestabilan, potensi longsor pada lereng. Pada penelitian ini banyak menggunakan metode Ground Penetrating Radar (GPR) kehandalannya dal...

More innovative test methods may measure language learners’ test performance more accurately, contributing to much fairer decisions. This study examined Iranian language learners’ performance on cloze-elide test as an innovative, integrative test method. It specifically focused on investigating whether personality types correlated with their performance and whether personality types could predi...
