The mesoscopic structure of rocks determines their strength and deformation characteristics. grain pore size distribution granite samples buried depth 1600 m to 1900 in a goldmine Shandong Province are measured by polarizing microscope low-field nuclear magnetic resonance. splitting test is carried out the acoustic emission signal obtained real time using an electro-hydraulic servo press PCI-2 ...

Viscoelastic properties are one of the most fundamental chiral liquid crystals. In general, their determination is not a straightforward task. The main problem multitude physical parameters needed to determine value elasticity and viscosity constants. It also necessary consider character respective phase. This particularly important in case phases such as ferroelectric antiferroelectric or blue...

Abstract Nero’s Temple at El-Ashmonein archaeological site, in Minia (middle of Egypt), is considered one the most important all temples Nero. This temple dates back to 1520 BC–1075 BC New Kingdom and was reused era Nero (the Fifth Emperor Rome). The construction materials are severely decayed from surrounding environmental impacts, especially contaminated water sources. main objective this pap...

   The study area is located in the northeast of Iran. Miankuhi Formation is 500m thick and comprises homogeneous shales, brown granular sandstone and siltstone. In this study, 45 samples were taken from Miankuhi shales and sandstones in order to determine their tectonic origin by using a polarizing microscope. Samples were analysed by X-Ray Fluorescence (XRF) method to determine their chemical...

Abstract The segmentation of minerals visible in sandstone thin-sections is a necessary part microscopic estimation mineral composition, the most important petrographic and sedimentological studies. This process often hard task due to difficulty determining exact boundaries between grains, mainly caused by secondary alteration minerals, etching grains pore-space filling cements. Structural feat...

Polar codes are recursive general concatenated codes. This property motivates a recursive formalization of the known decoding algorithms: Successive Cancellation, Successive Cancellation with Lists and Belief Propagation. This description allows an easy development of the first two algorithms for arbitrary polarizing kernels. Hardware architectures for these decoding algorithms are also describ...

In the past, polarizing filters were attached to cars’ halogen headlights reduce glare for other vehicles. However, absorbed a significant amount of light and made it difficult drivers see properly. Coupled with overheating issues numerous technical logistical limitations, polarized automotive lighting systems have not become widespread. this research, we propose using LED system improve driver...
