Dolgu uygulaması karayolu ve demiryolu inşaatlarında sıklıkla karşılaşılan bir uygulamadır. Bu çalışmada dolgu stabilizasyonunu sağlamak amacıyla yapılan geleneksel sanat yapılarından olan betonarme istinat duvarı ile geosentetik (geogrid) donatılı yapısı maliyet, yapım süresi, hizmete açılma estetiklik hizmet ömrü kriterleri dikkate alınarak karşılaştırmalı olarak analiz edilmiştir. Mukayesele...

We have investigated the stimulated emission properties of Nd(3+) doped La(2)O(2)S powders at room temperature as a function of pumping energy density, excitation wavelength, and Nd(3+) ion concentration. The absolute stimulated emission energy has been measured. Expressions for the slope efficiencies and lasing thresholds as a function of rare earth concentration and pumping wavelengths, which...

seepage in earth fill dams is one of the important factors that may cause the erosion and slope instability if it is ignored. therefore, it is crucial to calculate the leakage discharge through the body of dam and foundation, to prevent economic and life hazards by considering technical and economical issues. in this research, the seepage analysis of the body and the stability of the upstream a...

We report a large mode-area holmium-doped ZBLAN waveguide laser operating at 2.9 μm, which was pumped by a 1150 nm diode laser. The laser is based on ultrafast laser inscribed depressed cladding waveguides fabricated in uniformly rare-earth-doped bulk glass. It has a threshold of 28 mW and produced up to 27 mW of output power at an internal slope efficiency of approximately 20%.

The use of piles for slide stabilization is considered among the most important innovative reinforcement techniques. Piles have been successfully used in many situations to stabilize slopes or as parts a stability improvement. Our case study Tlemcen section. left side roadway collapsed following downstream side. Inclinometer readings showed signs instability with slip depth about 9m near motorw...

Rain fade slope is one of fade dynamics behaviour used by system engineers to design fade mitigation techniques (FMT) for space-earth microwave links. Recent measurements found that fade slope prediction model proposed by ITU-R is unable to predict fade slope distribution accurately in tropical regions. Rain fade measurement was conducted in Kuala Lumpur (3.3 N, 101.7 E) where located in heavy ...
