this paper assesses the design guidelines of different classification codes for the liquefied natural gas carriers considering the effect of liquid sloshing. with regard the increasing importance of lng carriers in today’s marine transportation, and also considering that the marine accidents involve significant loss, classification societies by regulating national and international standards ai...

For five consecutive eyes from five patients with liquefied aftercataract, Nd:YAG laser treatment significantly reduced high-order aberrations. Two eyes showing a reduction in positive spherical-like aberrations after treatment showed a postoperative myopic shift, while three eyes showing no change in spherical-like aberrations demonstrated hyperopic or only a slight myopic shift.

The central wavelengths of the resonance bands are critical aspect of the performance of long period gratings (LPGs) as sensors, particularly for devices designed to operate near the phase matching turning point (PMTP), where the sensitivity to measurements can vary rapidly. Generally, LPGs are characterized by their period, but the amplitude of the amplitude of the index modulation is also an ...

We present two novel schemes for refractometry based on a long-period fiber grating- (LPG-) based Michelson interferometer. These schemes are designed to overcome the measurement dependence of previously demonstrated LPG-based refractometry on the immersion depth. The first utilizes an unshielded LPG and the second, a shielded one. Both schemes were tested over a certain refractive-index range,...

Liquefied natural gas (LNG) is being developed as a heavy vehicle fuel. The reason for developing LNG is to reduce our dependency on imported oil by eliminating technical and costs barriers associated with its usage. The U.S. Department of Energy (DOE) has a program, currently in its third year, to develop and advance costeffective technologies for operating and refueling natural gas–fueled hea...

The March 2011 nuclear accident at the Fukushima Daiichi nuclear power station affected both shortand long-term energy-security in Japan, resulting in crisis-driven, ad hoc energy policy and, because of the decision to shutter all nuclear reactors, increased the country’s demand for fossil fuels, primarily natural gas. However, the effects of the accident on energy security were not restricted ...
