Failure Analysis and Optimization Design of Wing Skin Unbalanced Lay-Up by Junli Wang, Jinyang Li

“…To clarify the influence of the unbalanced coefficient and the change in lay-up angle on the failure characteristics of the laminate in the static aeroelastic problem of the aircraft, numerical simulations were performed based on the classical laminate theory and the Tsai-Wu failure criterion, as well as the fluid-structure coupling calculation method. The structure’s stress-strain and failure curves are found to decrease as the unbalanced coefficient increases. …”

Automatic control technology of low frequency and low voltage splitting devices using wide area measurement information by Mingliang GAO, Bo ZHUANG, Xuefei NIU, Mouying LI

“…Aiming at the problems of large noise content of wide area measurement information of power grid and difficulty in controlling oscillation damping in interconnected areas of power grid, an automatic control technology of low frequency and low voltage splitting devices using wide area measurement information was proposed.Based on the wide area measurement system (WAMS), the wide area measurement information of the power grid during the operation was obtained.After the noise contained in the wide area measurement information of the power grid was removed by the wavelet decomposition de-noising method, the power grid low-frequency oscillation identification method based on Prony was used to identify the power grid oscillation region and oscillation value.Then, based on the grid oscillation region and oscillation value, the oscillation center voltage and positioning coefficient were calculated and used as input to design the automatic control flow of the low frequency and low voltage splitting device, so as to realize the automatic control of the low frequency and low voltage splitting device.The experimental results show that this method can effectively remove the noise contained in the wide area measurement information of the power grid, the maximum error of the oscillation damping value in the interconnected area of the power grid is only 0.01, and this method can effectively control the low frequency and low voltage splitting device.…”

"An overgrown monster": London in Some Eighteenth-Century Writings by Hélène Dachez

“…Londres, lieu malléable par excellence, où alternent circulation déréglée et menace de stase, devient le lieu de tous les excès, et les auteurs mettent en avant un processus de contamination réciproque entre les êtres répréhensibles qui y pullulent et la capitale parasite, corrompue et corruptrice.Il faut alors souligner et analyser le traitement particulièrement original que propose Samuel Richardson (qui partage avec Samuel Johnson un amour immense pour la capitale), dans Clarissa, où Londres joue un rôle primordial dans le destin des personnages et dans l’économie du roman.…”

A Methodology for Clustering Items with Seasonal and Non-seasonal Demand Patterns for Inventory Management by Burak Kandemir

“…In this paper, we propose two algorithms, one based on statistical analysis and the other an unsupervised machine learning algorithm using K-means clustering, both of which differ-entiate seasonal and non-seasonal products where an item’s variation is evaluated with respect to seasonality of the product group it belongs to. We then calculate the efficiency of two proposed approaches by standard deviation within each cluster and absolute difference of percentage of volume and item numbers. …”

Exploring confinement in Anti-de Sitter space by Riccardo Ciccone, Fabiana De Cesare, Lorenzo Di Pietro, Marco Serone

“…For the Neumann boundary condition, the lightest scalar operator is found to have a positive anomalous dimension, in agreement with the idea that this boundary condition extrapolates smoothly to flat space. The perturbative calculations are made possible by a drastic simplification of the gauge field propagator in Fried-Yennie gauge. …”

Design of concatenated Hash-Polar code based on segmented CRC code by Zhengjie LI, Shunlan LIU, Xu ZHANG

“…As a linear block code, the polarization code has a lower coding complexity and a definite structure, but when it has a short or medium code length, the performance will be reduced.A design method of concatenated HashPolar codes based on segmented cyclic redundancy check (CRC) codes was proposed, which was based on the original Hash-Polar code and used CRC segmented check for double check.The segmented CRC code could assist the path measurement in the decoding process, that was, modify the decoding path, so as to improve the reliability of path selection and the performance.In addition, the segmented check was to add the check code dispersedly to the input information sequence.If the CRC failed during decoding, the decoding path could be terminated in advance to save unnecessary decoding calculations.Finally, at the end of the decoding, Hash check code verified the modified L paths and selected the best decoding path.The simulation results show that the design method proposed has better bit-error-rate performance than CRC-assisted Hash-Polar (Hash-CRC-Polar).In the Gaussian channel, when the code length is 128 bit, the code rate is 1/2, and the bit error rate is 10^-3, the Hash-Polar code based on the segmented CRC code proposed achieves a gain of about 0.25 dB over Hash-CRC-Polar.…”
