Development of a method for the combined control of the hardness of winding textile package

Analysis of methods for determining the hardness of the winding shows that all existing methods require a lot of labor and time. When measuring the layer-by-layer hardness, the known methods do not allow obtaining continuous values, and in the case of measuring the hardness of packages of complex shape (conical bobbins, cops, spinning cobs, etc.), it requires a calculation using cumbersome formulas. In this case, the main difficulties arise in determining the volume of the layers of the winding, which in the general case have a complex configuration, and due to defects in the winding may have an irregular shape. Obviously, the described technique is rather cumbersome, and a lot of measurements and calculations are required to obtain a graph of the change in the winding hardness along the package radius. The construction of a graph of the change in hardness along the generatrix using a special device is generally problematic, since placement of more than three sources on the device is impossible due to the size of the meters, and the construction of the curve by three points cannot be considered satisfactory. Winding hardness is one of the most important parameters, on which many technological properties of the package depend. Indeed, with an increase in the hardness of the winding, the amount of material in the same volume increases, which makes it possible to replace packages less often, both on the machine that forms them, and at the subsequent transition. As a result, the equipment useful time increases. It was found that the hardness of the winding is closely related to its rigidity, and hence to the stability during transportation. The hardness of the winding affects the permeability of the package when it is treated with solutions. In this case, a huge role is played not only by the average value of the hardness, but also by its distribution over the layers

Mechanical Properties and Apparent Morphology of Sandstone under Chemical Corrosion Conditions

The rise of the underground engineering provides more guarantee and convenience for human life, and the mechanical property of the surrounding rock is gradually lost, which has great harm to the long-term stability of the project. in that context of the environmental background of the project under the base of this article, firstly, a sandstone sample is taken at the site, a test sample of suitable size is made in the chamber, and then the test sample is arranged in a special device to simulate the simulated corrosion in the background of the simulation environment, Finally, the mechanical properties and apparent morphology of rock samples under different corrosion conditions were studied. The results show that the loss of the mechanical properties of the rock under different corrosion conditions is large, and the change of the acid and alkali of the solution is larger and the rock is The more obvious the damage difference of mechanical properties is, the more obvious the difference is that the pH value is from low to high, the peak strength loses 52%, 27.7%, 7%, 23%, 54% respectively. The failure morphology of corroded sandstone shows special conical morphology. Finally, the equivalent strain principle is used to interpret the corrosion of sandstone. The research results can be used for reference and reference for the long-term stability control of underground engineering based on water corrosion environment.

Effects of electrically transferred molecular information on the germination of garden cress

We followed a hypothesis that biologically relevant information from various substances can be non-chemically transferred to organisms through a combination of a high voltage electric field that can stably imprint information into water or a water solution. A special device was constructed, and a thoroughly tested biological sensor system (i.e. cress seedlings exposed to a defined heat stress), was used. The results demonstrate a clear evidence of biological effects of electrically imprinted information of biologically active substances into water solution, however not necessarily with an obvious connection to the effects of the original (donor) substance. The growth reaction of cress seedlings was either stimulatory or inhibitory, depending on the time of the application. Keywords: Molecular information, electromagnetic transfer, heat stress, herbicide, cytokine, cress, germination.

Determination of probabilistic characteristics of random values of estimates of the Lyapunov function when describing a physical process

The applied application of the Lyapunov characteristic function is determined by the properties of its estimates. Probabilistic characteristics of estimates of the Lyapunov characteristic function are described for the first time. The probabilistic characteristics of random values of estimates of the Lyapunov function are empirically estimated using statistical methods. The Matlab package has developed a model of a special device for obtaining estimates of the characteristic function by a direct method. A quasi-deterministic signal is fed to the input of the model, the instantaneous values of which are distributed according to the arcsine law, and an array of values of estimates of the Lyapunov function is obtained at the output, which is used to estimate the probabilistic characteristics of these estimates. Statistical estimation was performed by an indirect method. It is established that the values of the estimates of the Lyapunov characteristic function are distributed according to the normal law. The results of the research will be useful in engineering calculations, for example, when detecting message transmission errors in modems with a modulated characteristic function.

Smartphone-based Handwritten Signature Verification using Acoustic Signals

Handwritten signature verification techniques, which can facilitate user authentication and enable secure information exchange, are still important in property safety. However, on-line automatic handwritten signature verification usually requires dynamic handwritten patterns captured by a special device, such as a sensor-instrumented pen, a tablet or a smartwatch on the dominant hand. This paper presents SonarSign, an on-line handwritten signature verification system based on inaudible acoustic signals. The key insight is to use acoustic signals to capture the dynamic handwritten signature patterns for verification. Particularly, SonarSign exploits the built-in speakers and microphones of smartphones to transmit a specially designed training sequence and record the corresponding echo for channel impulse response (CIR) estimation, respectively. Based on the sensitivity of CIR to the tiny surrounding environment changes including handwritten signature actions, SonarSign designs an attentional multi-modal Siamese network for end-to-end signatures verification. First, multi-modal CIR streams are fused to extract representative signature pattern features from spatio-temporal dimensions. Then an attentional Siamese network is elaborated to verify whether the given two signatures are from the same signatory. Extensive experiments in real-world scenarios show that SonarSign can achieve accurate and robust signatures verification with an AUC (Area Under ROC (Receiver Operating Characteristic) Curve) of 98.02% and an EER (Equal Error Rate) of 5.79% for unseen users.
