Watermarking based on difference expansion and genetic algorithms
(2015)
Security problems that recently appeared in transmission and storing of digital content can be solved by using watermarking. Reversible watermarking is the election in medical and defense imagery because these security ...
Behavior of collapsible loess saturated with NAPL in confined compresion tests
(2015)
Loess from the central area of Argentina are unstable soils with mechanical properties highly dependent on moisture content. These soils have a macro skeleton that collapses when either loads increase and/or water enter ...
Determination of the stress state in the Andean Cordillera Frontal near the border between Argentina and Chile
(2015)
The initial state of stress is an important parameter in underground
excavations. From its knowledge, it is possible to calculate the stresses induced
around the excavation and the necessary support for stabilization. ...
Melatonin excretion in photoperiodic mammalian and bird species: chinchilla and Japanese quail
(2015)
Photoperiod is a powerful synchronizer of seasonal changes in physiology and
behavior. Melatonin (Mel) is considered a zeitgeber for seasonal photoperiodic
changes and plays a role in energy expenditure and body mass regulation.
Modeling of the small strain shear modulus on a fiber reinforced sand
(2015)
The mechanical behavior of fiber reinforced soils has been extensively
studied in the last decades. Previous studies have shown that inclusion of fibers
increases the shear strength of the reinforced soil. However in ...
