Security researchers and practitioners lack techniques to quantitatively evaluate the strength of security systems against a determined attacker. Currently, evaluation is either qualitative, such as through security certification standards, or ad-hoc, such as through penetration testing and auditing. In this paper, we propose a framework that if applied to security systems, would produce quanti...

The aim of the present mini meta-analysis was to compute the overall effect of mental fatigue induced by two cognitive tasks (namely, AX-continuous performance test or AX-CPT and incongruent Stroop test) on mood state, particularly on vigor, assessed using the Brunel Mood Scale (BRUMS), in both physically active and trained subjects. Search strategy was taken from a systematic review recently c...

In this study, three-dimensional simulations of cone penetration tests (CPT) in cemented sandstone have been investigated using the Discrete Element Method (DEM). We generated realistic grain size distribution numerical Ustyurt-Buzachi Sedimentary Basin samples. Numbers CPT at different bond strength values were performed with penetrometer vertically moved down a constant rate. The results real...

Random field modelling of soil variability allows significant statistical results to be inferred from field data; moreover, it provides a consistent framework for incorporating such variability in reliability-based design. Cone penetration testing (CPT) is increasingly appreciated because of its near-continuity and repeatability. Stressnormalised CPT parameters are included in widely used engin...

Cone penetration test is one of the most common in-situ tests for pile analysis given that by its analogy as a model pile, the measured cone resistance and sleeve friction can be employed for estimation of pile unit toe and shaft resistances, respectively. In this paper, group method of data handling (GMDH)-type neural networks optimized using Genetic algorithms (GAs) are used for modelling the...

Abstract Studies in recent decades demonstrate the significant effect of stress configuration (e.g., vertical and lateral confinement) on shear strength or, this study, cone penetration test (CPT) results. Addition a surcharge over ground changes condition, consequently, CPT tip resistance. In results different CPTs conducted before after backfilling with various thicknesses land development pr...

Pondasi tiang pancang merupakan struktur bagian bawah yang menumpu pada tanah keras atau tumpuan padat dan bekerja sebagai penopang berada diatasnya, jika bawahnya kokoh maka atas akan tetap berdiri kokoh, sebaliknya tidak kuat menahan atasnya runtuh, Penelitian ini dilakukan untuk mengetahui daya dukung pondasi tunggal kelompok dengan menggunakan metode Mayerhoff 1956 Luciano Decourt 1996 berd...

BACKGROUND Coronary endothelial function testing using acetylcholine is not routinely available, while non-pharmacological cold pressor testing (CPT) is considered an endothelial stressor. Noninvasive cardiac magnetic resonance imaging (CMRI) myocardial perfusion reserve index (MPRI) can detect coronary microvascular dysfunction (CMD). We evaluated if CPT stress CMRI MPRI could detect invasive ...
