Our objectives were to characterize colonic viscoelastic properties of the human descending colon by assessing pressure-volume (P-V) relationships during barostatic balloon distension. In 16 healthy subjects, a balloon was inflated to 44 mmHg and then deflated to 0 mmHg in 4-mmHg steps at 10, 30, and 60 ml/min, allowing volume fluctuations to stabilize at each pressure increment. Thereafter, th...

High-gain optical parametric amplification is an important nonlinear process used both as a source of coherent infrared light and nonclassical light. In this work, we experimentally demonstrate approach to that enables extremely large gains with low energy requirements. conventional media driven by femtosecond pulses, multiple dispersion orders limit the effective interaction length available f...

In this paper, the temperature dependence on optical absorption cross section of the core shell bimetallic nanoparticles (NPs) is investigated in quasi static approximation. Temperature dependence of the plasmon resonance is important issue because of recent applications of NPs of noble metal for heat treating of cancer and the computer chips. The effect of temperature on surface plasmon resona...

In this study, the dynamics of tether cables (TCs) that connect a surface ship and walking robotic vehicle on seabed are numerically investigated. The main aim study is to develop reliable prediction model for dynamic behavior TCs attached robot. This system consists ship, underwater manned robot (UMSWR), TC, winch. comprised mathematical modeling numerical simulations developed governing equat...

16 In geophysical electromagnetic methods, time-varying magnetic fields are measured at Earth’s surface that are produced by electrical currents inside the Earth in order to constrain subsurface conductivity and geological structure. These methods are widely used for mineral exploration and environmental investigations, and are increasingly being used in hydrocarbon exploration as well. Forward...

We study the theory of best approximation in tensor product and the direct sum of some lattice normed spacesX_{i}. We introduce quasi tensor product space anddiscuss about the relation between tensor product space and thisnew space which we denote it by X boxtimesY. We investigate best approximation in direct sum of lattice normed spaces by elements which are not necessarily downwardor upward a...
