Study on Interaction Relationship for Submarine Pipeline with Axial Corrosion Defects

Corrosion is one of the main reasons to cause the operation accident of submarine oil and gas transmission pipelines. As the major corrosion pattern in submarine pipelines, the effects of corrosion clusters consisting of the adjacent corrosion defects on failure pressure are investigated through non-linear large-deformation finite element method. Typically, the failure behavior and limit strength of submarine pipeline with axial groove- groove corrosion defect pair exposed to interhal pressure are analyzed. The effects of corrosion depth and axial spacing between a pair of corrosion defects on failure pressure are concluded. An interaction relationship for corrosion defects in pipelines, as well as prediction formulations for assessing the remaining strength of corroded pipelines are proposed. The expressions based on the proposed interaction relationship give more accurate results than the methods used in the existing design guidelines.

Dynamic Scaling of the Generalized Complementary Relationship Improves Long-term Tendency Estimates in Land Evaporation

Most large-scale evapotranspiration(ET)estimation methods require detailed information of land use,land cover,and/or soil type on top of various atmospheric measurements.The complementary relationship of evaporation(CR)takes advantage of the inherent dynamic feedback mechanisms found in the soil−vegetation−atmosphere interface for its estimation of ET rates without the need of such biogeophysical data.ET estimates over the conterminous United States by a new,globally calibrated,static scaling(GCR-stat)of the generalized complementary relationship(GCR)of evaporation were compared to similar estimates of an existing,calibration-free version(GCR-dyn)of the GCR that employs a temporally varying dynamic scaling.Simplified annual water balances of 327 medium and 18 large watersheds served as ground-truth ET values.With long-term monthly mean forcing,GCR-stat(also utilizing precipitation measurements)outperforms GCR-dyn as the latter cannot fully take advantage of its dynamic scaling with such data of reduced temporal variability.However,in a continuous monthly simulation,GCR-dyn is on a par with GCR-stat,and especially excels in reproducing long-term tendencies in annual catchment ET rates even though it does not require precipitation information.The same GCR-dyn estimates were also compared to similar estimates of eight other popular ET products and they generally outperform all of them.For this reason,a dynamic scaling of the GCR is recommended over a static one for modeling long-term behavior of terrestrial ET.

The Relationship Equation & Relationship Circle. The Importance of Reciprocal Interaction in Functional Relationships, Role of Context & the “Happinewness” Key.

Truly opposite is defined by identity of units with complementary anatomy or structure to form a pair,e.g.male and female.Complementary or corresponding structure or form permits reciprocal function of these units or“opposites”.Focus on“Identity”or“function”determines one’s view as to whether these units are“opposites”or“complementary”.“Identity”is unique&exclusive,whereas,function requires inclusivity,specificity&reciprocal interaction,contributed to by both units to form a dynamic partnership or pair.Contextual interaction matters as it permits an inclusive view.Inclusion&awareness of surroundings that impact on relationships and/or personal interaction is represented here by a surrounding circle or sense of purpose and represents the extension of immediate context involving both units in a paired relationship of structural complementary units within their encompassing surroundings or contextual field.Contextual reference is the ethical key to understanding situations&circumstance so serves as the key to ethics,morality&relationships.The Relationship Equation,E=1=m.c-1,provides a simple model of understanding usually viewed as complex relationships.It offers an approach to solving identity issues by viewing these as complementary and functional rather than as opposites.In place of identity as the focus it introduces context and reciprocal interaction of complementary units of a pair.Identity as part of a whole transfers the focus from self to other or both and to an awareness of higher purpose in the Oneness of function of Creation as(m.c-1)=E=1.Environmental influence is taken into account by viewing the Eco-social environment or Eco-society as important.Impact of environment on one or other unit in a pair or on both&vice versa affects relationships.Resilience&adaptation to environmental change leads to evolution when the pair thrives better in this new Eco-social environment.Being part of a functional whole,as a functional unit or as a functioning pair,adds purpose and reason for the Creation,all of Creation,including self,as one is included in all!Application of the Relationship Equation is relevant to health&wellbeing,parenting,biology,law&health law,political science,society&evolution.It is also valuable when utilized as a resolution tool as it offers functional outcomes and sense of purpose on the basis of objectivity,trust and truth to overcome conflict arising from a highly sensitized identity-oriented focus.Contextual&reciprocal units in functional pairs replace self as the basic functional principle of the whole of existence.Application of this understanding has preventive as well as therapeutic relevance.It may be used as a guide in upbringing,parenting and child care as well as conflict resolution in personal,social&political scenarios locally,nationally,internationally,globally&universally.It is the“happinewness”key.

基于共生理论的“互联网+”企业创新生态系统关系治理模式研究

促进“互联网+”企业创新生态系统可持续发展要求妥善处理好系统中的关系风险。目前“互联网+”企业创新生态系统的相关研究在关系治理、主体互动关系及其可能产生的关系风险和治理机制等方面仍不足。为此,基于共生理论,通过对现有文献的梳理汇总,探讨“互联网+”企业创新生态系统3种关系治理模式的互动方式、关系风险和治理机制,并以小米(小米科技有限责任公司)、抖音、微信小程序等典型案例分析验证。研究发现:偏利共生型关系治理模式下,机构型创新主体为主导者,以效率为导向,实现创新行为的控制,其治理机制为核心企业控治;寄利共享型关系治理模式下,社群型创新主体为主导者,以公平为导向,实现创新关系的扩散,其治理机制为“社群自治+核心企业同治”;互利共赢型关系治理模式下,创新主体间平等合作,以民主为导向,实现创新效能质的提升,其治理机制为社群与核心企业共治。此外,这3种关系治理模式均以技术和创意等资源作为生态系统战略利益的根本来源,并借助其向创新主体表达自己的价值导向。然而,不同的关系特征会引起不同的共生风险,主要包括创新资源投入不平衡、主体利益分配不公平、竞合关系维持不稳定。基于此,要明确“互联网+”企业创新生态系统中主体的角色,核心企业应根据情况选择不同的关系治理范式。

连通性视域下高校师生互动类型、机制与策略

人际互动的基本前提是人与人之间的关系连通。在连通性视域中,高校师生关系可以区分为“无连通、弱连通和强连通”三种状态,并因此发展出“互动缺失、弱互动、强互动”三种互动类型。师生互动强度与教学效果之间存在明显正相关。师生强互动和关系强连通的获得机制主要是个体层面的特征同质性机制和群体层面的结构平衡化机制。实践中,通过调整教学策略、完善制度保障、建构支持合力等举措,可以增进师生之间的同质性因素,强化师生群体的结构平衡,进而建构起师生强互动和关系强连通,有效提升教学效果。

长江中游戴家洲河段滩群联动演变及其对航道工程的响应机制

航道浅滩演变与滩槽形态调整具有强关联性,识别滩槽形态、河床冲淤与航道工程的响应关系,对评估航道工程实施效果具有重要意义。以长江中游戴家洲河段为对象,采用1954—2022年期间实测水沙和地形资料,解析滩群演变联动关系及对航道工程的响应机制。结果表明:①自然水沙阶段(2008年以前),巴河边滩与池湖港边滩关联性强,池湖港边滩淤涨并减弱了燕矶节点挑流作用,加速了戴家洲洲头低滩上延,而巴河边滩淤涨使得戴家洲洲头低滩冲刷,但流域来沙量减少增加了洲头低滩冲刷速率;戴家洲汊道分流关系不稳定且汉口站相同流量条件下的右汊分流比为减少态势,来沙量低的大水年份加速戴家洲右缘蚀退并为乐家湾边滩淤宽提供了空间。②航道工程影响阶段(2008年以来),航道工程实施使得戴家洲洲头低滩上延,其右缘冲刷应引起重视;戴家洲汊道进口段航道工程压缩了河道横向空间并加速了巴河边滩冲失趋势,池湖港边滩侧蚀使得分汊段水流分散程度增加,不利于汊道进口段浅滩水动力的稳定或增强;戴家洲右缘洲体守护后的完整性增强,乐家湾边滩由淤涨转为冲刷过程形成的分离体进入航槽并碍航,6m水深航道工程实施后乐家湾边滩完整性增强,右汊中下段浅区航道条件改善。
