Field-scale bio-cementation tests to improve sands

Strength-Flow Parameters of Loose Silty Sands From Piezocone Tests

Piezocone penetration tests with dissipation phases are particularly useful for geotechnical site characterization. They also provide three independent readings with depth from a single sounding as well as time-rate information. In past investigations, only silty sands with specific silt content have been tested and complete sets of tests have not been conducted to evaluate the influence of dif...

Effect of Cementation on the Shear Strength of Tehran Gravelly Sand Using Triaxial Tests

Bio Inspired Technique to Improve the Performance of VANETs

The Vehicular Ad-Hoc Network, or VANET, is an expertise that usages moving cars as nodes in a network to generate a moveable network. VANET turns each contributing car into a wireless router or node, permitting cars roughly 100 to 300 meters of each other to associate and, consecutively, form a network with an extensive range. Since vehicular ad hoc networks require the transmission of the safe...

Non-parametric tests of returns to scale

This paper discusses various statistics for testing hypotheses regarding returns to scale in the context of non-parametric models of technical efficiency. In addition, the paper presents bootstrap estimation procedures which yield appropriate critical values for the test statistics. Evidence on the true sizes and power of the various proposed tests is obtained from Monte-Carlo experiments. This...
