Determination of Diffusion Coefficients of Lithium in Solid Electrolyte LiPON

A structural model of LiPON solid electrolyte, containing elements that simulate drift conductivity, diffusion conductivity, and leakage current was proposed. The dependence of the impedance of the structural model on frequency was calculated, and the parameters of the model at which the theoretical curve best approximates the experimental Nyquist diagrams were determined. Based on these data, the ion diffusion coefficient and conductivity of LiPON were calculated, which are D1 = 1.5 × 10−11 cm2/s and σ = 1.9 × 10−6 S/cm, respectively.

On external influences on the radioactive decay rate fluctuations

The evolution of views on the possibility of external influence on the process of radioactive decay is briefly presented. Such an effect can lead to the appearance of periods in the time series of the radioactive decay rate fluctuations, which have been the subject of intensive study in the last decade. Two mechanisms for identifying periods are considered: the study of deviations from the theoretical curve of the radioactive decay law and the study of the properties of fluctuations. It is shown that the latter method leads to a universal spectrum of periods observed not only in the time series of the radioactive decay rate fluctuations, but also in the time series of fluctuations of processes of various nature. The main object of our study are periods in the radioactive decay rate fluctuations. The presence of such periods suggests the possibility of external influence on the process of radioactive decay. Therefore, we briefly consider the evolution of views on the possibility of such an effect. To do this, we distinguish several stages. The division into stages is only partially historical, but, mainly, each stage characterizes a certain ideas that is implemented in it.

Sand curve facelift: Empirical to polynomial model and the effect on the tomogram

An empirical thickness versus time relationship sand curve has been established in the Rub’ al-Khali desert and verified by a theoretical curve from the direct measurements of sand. The empirical sand curve has variable success in other areas of Saudi Arabia. We established a theoretical sand curve model to determine the single-way time in dry sand. Tomographic modeling of a higher resolution 3D seismic survey contributes more data to refine the relationship. Polynomial curves were used in the calculation of near-surface static corrections to improve the solution for low-relief structures.

Experimental Investigation of the Interface between Synthetic and Glass Fibers and Lime-Based Mortars

In this article, the cohesion between fiber reinforcement and lime-based mortar is experimentally investigated using so-called pullout test. The experiment is based on the progressive pulling out of the fiber from the matrix. Comparing the experimental load-displacement diagram with the theoretical curve from the analytical model, the micromechanical parameters describing the fiber-matrix interface are evaluated. In the study, several types of synthetic and glass fibers are considered as well as two types of lime-based mortars. The first one is pure lime, while the second one has lime-metakaolin matrix.

Design Calculation for Wedge Cam of Small Roller Centering Three-Jaw Jig

As wedge cam contour’s conventional equation of small roller centering three-jaw jig calculated by classic method is complex and difficult to be used for processing directly, a numerical calculation method for the wedge cam contour is proposed. Firstly, structure and working principle of centering small roller jig is introduced. Secondly, a new numerical calculation method sampling for wedge cam contour using equal step is presented, which can be obtained sampling points expression by numerical calculation model. Then,these samples points assignment will be fitting and interpolation in accordance with quadratic polynomial curve. The equation of quadratic polynomial interpolation on these sampling points these sampling will be obtained, which can be directly applied to NC programming. At last, through comparing fitted quadratic polynomial curve calculated by the numerical method with the theoretical curve calculated by classic method, it is found that the comparison tolerance is much smaller than conventional processing tolerance which is produced by using the theoretical curve for processing. The comparison tolerance is analyzed, refining the sampling step length and using piecewise fitting and interpolation loop calculation method is proposed,which can further improve numerical calculation accuracy to satisfy the requirement of higher and higher positioning. Therefore, it can be concluded that the numerical calculation method can effectively solve the difficult processing problem of wedge cam contour, which will produce better economic benefits.

Rotating Angle Error Influence to Grinding Aspheric Optical Component

An analyzing rotating error method has presented based on grinding aspheric optical component. A coordinate transform has been done between the new and original coordinates system in view of the rotating error in installing parts, further, the rotating angle error model has deduced between actual curve and theoretical curve. The surface error formulas can be used for variety of rotary conic aspheric curve, depending on the requirements of the parts surface accuracy, quantitative adjustment target can be given in installation and adjustment process before grinding. Based on the rotating error formulas, the calculating example shows that installation angle bas various different influence to surface shape error, the error decreases with the θ decreasing, the surface error is reduced a magnitude accordingly when the angle is reduced to a magnitude. The parts surface error is up from-0.0030mm to-0.0448mm when the rotating angle increasing from 0.1° to 1°. When θ is constant, the surface shape error increases with steepness increasing, installing rotating angle requirement is more stringent for all the large steepness parts.

Study on Integral Minimum Method Aspheric Surface Measuring

Based on the traditional aspheric surface shape measuring difficulties, a kind of new integral minimum method is presented, whose guiding idea of this method is to make right position for the parts theoretical curve and the measuring curve to sure the error sum to be minimum. The definition of integral minimum method is elaborated, for example parabolic, its surface shape error is discussed, and the right position expression is derived for the parts theoretical curve and the measuring curve. The calculating example shows that the integral minimum method is effective to analyze the real parts contour error due to the right position, so it should be a followed law objectively during the parts surface shape measuring.

Determination of the kinematic viscosity by the liquid rise in a capillary tube

We discuss first the valid time interval of a formula found in the literature which gives the theoretical distance run by a liquid which rises along a capillary tube as a function of time. A non-linear least square fitting of experimental data to this theoretical curve allows the measurement of the kinematic viscosity of the liquid. The goodness of the fitting for three different sets of experimental data given in the literature is above 99%.

Induced energy polarization of the vacuum and the rotational curve for the Galaxy

The theory of an induced energy polarized vacuum, as previously presented by the author (Penner. Can. J. Phys. 90, 315 (2012)), is used to generate a theoretical rotational curve for the Galaxy. The theoretical curve generated is found to be in good agreement with Sofue's (Publ. Astron. Soc. Jpn. 64, (In press) (2012)) compilation of observations. For the baryonic mass distribution and baryonic Tully–Fisher relationship that is used, the theoretical orbital velocity at the Sun's location is found to be (235 ± 15) km s−1. The galactic rotational velocity is then found to slowly fall from this value as it asymptotically approaches the value of (192 ± 15) km s−1.
