Purpose: In this research, we want to know whether elements such as interior design, coloration of input spaces, circulation, study hall and the reference section are satisfactory in the view of public library users of Yazd city (Iran) or not and to survey levels of satisfaction. Methodology: This is a survey research project that uses a researcher-made questionnaire. The research population i...
This paper presents a fully integrated linear Hall sensor by means of 0.8 μm high voltage complementary metal-oxide semiconductor (CMOS) technology. This monolithic Hall sensor chip features a highly sensitive horizontal switched Hall plate and an efficient signal conditioner using dynamic offset cancellation technique. An improved cross-like Hall plate achieves high magnetic sensitivity and lo...
The spin-orbit interaction in a solid couples the spin of an electron to its momentum. This coupling gives rise to mutual conversion between spin and charge currents: the direct and inverse spin Hall effects. The spin Hall effects have been observed in metals and semiconductors. However, the spin/charge conversion has not been realized in one of the most fundamental semiconductors, silicon, whe...
We study point-contact tunneling in the integer quantum Hall state of bosons. This symmetry-protected topological state has electrical Hall conductivity equal to 2e2/h and vanishing thermal Hall conductivity. In contrast to the integer quantum Hall state of fermions, a point contact can have a dramatic effect on the low-energy physics. In the absence of disorder, a point contact generically lea...
background:: this study developed a smart co 2 detector, which attach to the general ventilation system to reduce the gas level. methods: indoor air quality measurement was performed in five selected rooms between january 2015 to february 2015 using tsi q-trak tm indoor air monitor 7575. the perceived indoor air quality conditions was gathered using questionnaires adopted from the industrial co...
the problems of shortages and quality deterioration of water, have led to an increased interest in the reuse of treated grey water in many parts of the world. this study examined the suitability of locally available materials (beach sand, oyster shells, and charcoal) to treat grey water samples collected weekly from three halls of residence (unity hall, africa hall, and independence hall) on kw...
A numerical study is made of current distribution in small Hall bars with disorder. It is observed , in particular, that in the Hall-plateau regime the Hall current tends to concentrate near the sample edges while it diminishes on average in the sample interior as a consequence of localization. Also reported is another numerical experiment on a related, but rather independent topic, the breakdo...
We report the observation of a highly unusual Hall current in the helical magnet MnSi in an applied pressure P=6-12 kbars. The Hall conductivity displays a distinctive stepwise field profile quite unlike any other Hall response observed in solids. We identify the origin of this Hall current with the effective real-space magnetic field due to chiral spin textures, which may be a precursor of the...
The current work focuses on presenting specific Hall cells with high performance, and their corresponding parameters. The design, integration, measurements and model development for their performance assessment are necessary stages considered in the generation of the Hall cells. Experimental results regarding the Hall cells absolute sensitivity, offset and offset temperature drift are provided ...
