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...

When connected in small amounts, the impact of distributed generation (DG) on distribution system stability will be negligible. However, if its penetration level becomes higher, distributed generation may start to influence the dynamic behavior of the system as a whole. This paper presents a mathematical representation of a solid oxide fuel cell plant that is suitable for use in distribution sy...

It sounds good when knowing the penetration testers open source toolkit in this website. This is one of the books that many people looking for. In the past, many people ask about this book as their favourite book to read and collect. And now, we present hat you need quickly. It seems to be so happy to offer you this famous book. It will not become a unity of the way for you to get amazing benef...

Cone Penetration Test or CPT is one of soil investigation which used to determine the mechanical properties i.e., cone resistance and sleeve friction. Since several decades ago, often as a common thread physical such unit weight soil, behaviour type, etc. Thus, empirical approaches have been developed from various countries. However, these are not same condition in Indonesia. Therefore, it nece...

T paper develops a framework for measuring “tipping”—the increase in a firm’s market share dominance caused by indirect network effects. Our measure compares the expected concentration in a market to the hypothetical expected concentration that would arise in the absence of indirect network effects. In practice, this measure requires a model that can predict the counterfactual market concentrat...

This paper examines strategies of standard software vendors, in view of the existence of network effects on standard software markets. In particular, we analyze if and under which conditions penetration pricing can be considered as a promising strategy. Our work is based on a simulation model, which provides the opportunity to examine the impact of alternative pricing strategies on the distribu...

With the recent advances in biogeotechnics field and specifically microbially induced calcite precipitation (MICP), cone penetration testing (CPT) has become a valuable tool to overcome challenges associated with intact sampling of improved soils, evaluate spatial extent magnitude applied MICP treatment, assess consequential improvement engineering properties. Although CPT tip resistance (qc) c...
