We have computed the light transport in a bre in the geometrical optics approximation. The aim of this study is to compare the performances of single and double clad bres and to outline possible improvements to bre design.

Zirconium-based claddings with an outer chromium coating resistant to corrosion are studied and developed as evolutionary Enhanced Accident Tolerant Fuel (E-ATF) concept for light water reactors. However, in hypothetical LOss-of-Coolant-Accident (LOCA) conditions, following clad ballooning burst, the does not allow protect inner surface of cladding from High Temperature (HT) steam oxidation ass...

Because of the promising corrosion resistance and load-bearing capacity, titanium-clad (TC) bimetallic steel has gained increasing attention in ocean/coastal civil structural engineering. Due to double-layer nature TC steel, characteristics member’s geometry weld details are considerably different from that conventional members. Even though previous studies have conducted systematical clarifica...

: The long-term survival after lung transplantation (LT) is favorable in Japan. However, survivors LT are subject to late complications, including chronic allograft dysfunction (CLAD), malignancy, infection, and kidney disease (CKD) because of the need for lifelong immunosuppression. rates single cadaveric (CLT) living-donor lobar (LDLLT) higher than that bilateral CLT Here, we will describe ma...

In this paper, a new structure is provided for the dispersion compensating photonic crystal fibers in order to broaden the chromatic dispersion and increase the dispersion compensating capability in a wide wavelength range. In the structure, putting a combination of circular holes and a star structure in the inner core clad causes the dispersion coefficient profile to be broadened, and addition...

Titanium-clad (TC) bimetallic steel is an advanced composite consisting of metallurgically bonded titanium alloy and structural steel. This paper compared the high-cycle fatigue properties three types TC steels, including two hot-rolled bonding with different strengths explosion-bonded type. The steels were all manufactured from TA2 as cladding metal Q355B substrate metal, which thicknesses are...

Single optical fibres exhibiting minimum dispersion over the two optical wavelength windows of 1300 and 1550 nm region are essential for the multi-channel operation of dense wavelength multiplexed systems and networks. Design guidelines of dispersion-flattened optical fibres, over a wide band of optical spectrum, which have a triple-clad or segmented-core distribution of stepindex regions are d...

Spirometry is regarded as the primary tool for the evaluation of lung function in lung transplant (LTx) recipients. Spirometry is crucial in detecting the various phenotypes of chronic lung allograft dysfunction (CLAD), including restrictive allograft syndrome (RAS) and bronchiolitis obliterans syndrome (BOS) - note that these phenotypes potentially have different etiologies and therapies. Foll...
