Determination Of The Influence Of Spin-Off Roundess On The Value Of Spinning Yarn During Spinning, S.X Babadjanov, F.F Isxakova
Central Asian Problems of Modern Science and Education
The article presents the results of studies of the influence of the unevenness of roundness of the spinning rings on the tension of the yarn produced. It is also noted that if the shape of the ring is distorted, then the slider's trajectory is not a circle, but some closed curve that follows the shape of the ring, while, in general, at each subsequent time, the slider moves along a curve with a different curvature radius. The design scheme and the method for calculating the tension of the yarn from the profile of the ring are given.

Central Asian Problems of Modern Science and Education
The impressive progress in the fabrication of low-dimensional semiconductor structures during the past two decades has made it possible to reduce the effective device dimension from three-dimensional bulk materials, to quasi-two dimensional quantum well systems, to quasi-one dimensional quantum wires, and even to quasi-zero dimensional quantum dots. In this article we discussed about wave function in these structures.

Central Asian Problems of Modern Science and Education
The problem of the longitudinal vibrations of the elastic strerin of the longitudinal impact of the second free end of the end of the tape is settled on the basis of the second order (classic) differential equation. Depending on the nature of stroke endings and the nature and conditions of the impact, the initial and boundary conditions of the problem were found. To solve the problem, a structured block scheme was created, using a duplicate scheme. Created a structured block-scheme based on "Pascal" and the results were obtained.

Usu-Csu Na Lidar Data, Tao Yuan
Browse all Datasets
The naturally existing mesospheric Na layer, overlapping the upper mesosphere and lower thermosphere, provides an excellent tracer for lidar remote sensing. The Na Doppler lidar technique is designed to measure neutral temperature and wind profiles in the mesopause region (~ 80-110 km) by observing the thermal broadening and Doppler shift of the atomic Na fluorescence spectrum. Relocated from Colorado State University (CSU), the Na lidar at Utah State University (USU) has been operating since the summer of 2010, for roughly 1000 hours per year. Enabled by a pair of Faraday filters, it has a unique daytime observation capability to study …

A Model Archive For Sediment Transport Model Including Short-Lived Radioisotopes: Model Description And Idealized Test Cases, Justin J. Birchler, Courtney K. Harris, Tara A. Kniskern
Data
This dataset includes model input, code, and output used in the publication Birchler et al. (2018, Journal of Marine Science and Engineering), which used a coupled hydrodynamic-sediment transport-biogeochemical model to investigate the roles of resuspension, deposition, on biodiffusion on the behavior of short-lived radioisotopes in an idealized one-dimensional model setting. Model development for this project focused on incorporating radioisotope tracers into the sediment transport module in the Regional Ocean Modeling System (ROMS). As described in Birchler et al. (2018, Journal of Marine Science and Engineering), the model can account for supply and sorption of radioisotope tracers in the …

Mathematical Modelling Of Blood Flow, O. V. P. Joao, N. J. Khujatov
Central Asian Problems of Modern Science and Education
The paper presents the two-phase model to describe blood flow in large and in small blood vessels. Based on this model the study gives an explanation for long known features (effects) of blood flow in the vessels: dependence of the hematocrit (packed cell volume) on the diameter of the vessel, existence of cell-free plasma layer near the vessel wall, obtuse (as compared with the profile of Poiseuille flow) velocity profile of a blood; dependence of the blood viscosity on the diameter of the vessel. The researcher determines dependences of the blood rate and viscosity on the diameter of a blood …

Hygrothermal Performance Of Sealed Attics In Climate Zone 3a, Mikael Salonvaara, Achilles Karagiozis, William Miller
International Building Physics Conference 2018
Sealed attics with fiberglass have been in the US building codes for several codes cycles. Prior to the IRC 2018, air permeable insulation (such as fiberglass) was previously allowed to be deployed without continuous air impermeable insulation only in dry climate zones 2B and 3B in tile roofs systems. New research has revealed that asphalt shingles can also be allowed as implemented in the new IRC 2018 with a new addition to the section for sealed attics using air permeable insulations. The new building code also permits the use of air permeable insulation without air impermeable insulation in climate zones …

International Building Physics Conference 2018
In this paper the subjective evaluation of the indoor environment of a secondary school in Treviso (Italy) is presented. Field campaigns have been carried out during the winter season in order to assess people overall satisfaction about the environment, their behavior towards discomfort and their interactions with the building and the systems. A specific questionnaire has been elaborated, paying particular attention to the occupants target and to the questions needed to grasp not only the comfort feedbacks, but also the dynamics and the individual students’ attitudes that can influence the building energy performance. A first general evaluation has been elaborated …
