Expressions for the expected value of first mode damping ratio are derived by using 122 seismic responses from concrete buildings and 81 steel. The results include dissipation at soil-structure interface appropriate situations in which this source is not included model. Comparisons between models different complexity indicate appropriateness a single regressor, building height used. It shown that Fisher information about increases with number response cycles; result used to define weights...

Abstract BACKGROUND N 6 ‐Methyladenosine (m A) is a common messenger RNA (mRNA) modification that affects various physiological processes in stress responses. However, the role of m A modifications plants responses to herbivore remains unclear. RESULTS Here, we found an infestation brown planthopper ( Nilaparvata lugens ) female adults enhanced resistance rice N. . The methylome analysis ‐infested and uninfested samples was performed explore interaction between methylation mainly occurred...

The calibration accuracy of the binocular vision system is critical to its measurement accuracy. existing methods are typically utilized improve by nonlinear optimization previously obtained parameters in two-dimensional (2D) or three-dimensional (3D) space. Circular dot array targets widely used due their excellent noise immunity. However, projection ellipse center not circular marker center. eccentricity error will be substantial, especially with a large dip angle and close projection,...

In the context of ERP implementation, leadership is consistently found to be most important factor leading implementation success. However, studies focus on leader's strength and authority while ignoring role personal charisma plays in process. addition, there a lack study underlying process how acts during lifecycle implementation. this paper we first introduce charismatic from five dimensions, divide into three phases: adoption, secondary adoption assimilation. We then propose conceptual...

Multidirectional stereo vision sensors (MVSs) have been paid increasing attention in the fields of environment perception and 3-D reconstruction attributed to their advantage wide field view (FOV). Vision sensor setup requires parameters be calibrated accurately, which remains a challenging problem because discontinuity camera field. This article proposes flexible calibration method using an unconstrained target for quad-directional (QSVS) composed single dual mirror pyramid. We build...

In this paper, we present a real-time GPS software receiver design and implementation with 12 channels using correlator. A special equal-length CA code correlation method is introduced to increase the performance of signal processing efficiency. The result tested by real data MHz sampling under Pentium/AMD CPU, more simulation test done in DSP development platform. By comparison other correlator, new scheme only use 1/2 memory can procedure 20% speed improvement, 1/3 power lost.

Text matching is a core issue for question answering (QA), information retrieval (IR) and many other fields. We propose to reformulate the original text, i.e., generating new text that semantically equivalent improve degree. Intuitively, generated improves mutual between two sequences. employ generative adversarial network as reformulation model where there discriminator guide process. In this work, we focus on answers. The task rank answers based QA first without changing asker's intent,...

The binocular vision sensor composed of dual cameras is difficult to meet the requirements synchronous image acquisition in dynamic high-speed measurement, and mirrored (MBVS) single camera catadioptric components have become popular among machine applications. Existing sensors mostly comprise planar mirrors, which has disadvantage a small field-of-view (FOV). To extend measurement range MBVS, we proposed novel MBVS based on spherical mirrors. consists double mathematical formula FOV...

Reliability analysis based on failure mechanism takes advantage of unnecessary requirement for the field data, compared with traditional method probability statistics. Current reliability systems dependence mainly focus their views either level or process level, but barely from aspect mechanism. Our previous work used Mechanism Failure Tree (MFT) to show correlation mechanisms directly, it is unavailable express dynamic flow states. This paper proposed a modeling Petri net electronic...

Atomic magnetometers use the coherent precession of polarized atomic spins to detect and measure magnetic fields. When an off-resonant, linearly probe beam propagates through vapor cell, will cause a rotation its polarization plane. Measuring angle rotation, field can be calculated. In this paper, we introduce basic principles describe method angle. Then dual-phase lock-in amplifier (LIA) is proposed weak signal magnetometer. And design simulation for LIA based on Matlab/Simulink. Our...

In the vibration environment, electronic products may have fatigue failure, which affects its reliability level seriously. Therefore, it is important to estimate life of products. The common used model Steinberg necessary be studied. This paper analyzes derivation model. Assumptions and simplifications influence parameters on are Finally, applicability design guidelines summarized. It provides a basis for improvement design.

In this paper, a test system hardware platform based on PXI bus is proposed to the airborne power and typical distribution structure of large-scale Unmanned aerial vehicles (UAV). By researching structure, analyzing failure mode designing fault tree, diagnosis expert designed in UAVs, where forward reasoning knowledge base extension rule built solve non-exact inference complex via introducing certainty factor. The experiments illustrate that can effectively improve intelligent level has good...

Four new species of Empoasca (Empoasca Walsh) are described from China: E. (E.) dahaopingensis Qin & Liu, gutianensis Zhang lijiangensis and apibicruris Liu spp. nov. In addition, dymarka Dworakowska, 1984, is recorded China for the first time. apibicruris, placed in albipennis group with Dworakowsa, 1977. Habitus photos illustrations male genitalia provided.

Roller system equipment is always wear-out and deviates from its original position, which leads to the change of spatial relationship. Ulteriorly, it may also prompt a series problems such as wrinkle, off-tracking, edge overflow or bad profile. According current situation above, we have designed implemented roller's calibration based on total station. Firstly, measuring scheme scatter coordinates devised; then by using data processing algorithm, some significative parameters single roller...

Seven new species of Empoasca (Empoasca) Walsh, 1862 are described and illustrated. Five the belong to warchalowskii group: longa Zhang & Liu, megalophylla Qin paragucia Fletcher undulata vickiae spp. nov. The other two cannot be placed into a (Empoas- ca) dendritica Liu polyprocessa An additional 15 subgenus (Livasca) Dworakowska Viraktamath, 1978 recorded for first time from China.

This article aims to explore the effect of charismatic leadership on creativity.By using survey data from 314 employees a large tobacco company in China, we found that was positively related follower creativity, psychological ownership mediated and coworker helping support moderated relationship between creativity.Theoretical practical implications are discussed.
