Abstract Field observations and theoretical analysis are used to investigate the appearance of different nocturnal boundary layer regimes. Recent theoretical findings predict the appearance of two different regimes: the continuously turbulent (weakly stable) boundary layer and the relatively “quiet” (very stable) boundary layer. A large number of nights (approximately 4500 in total) are analyzed using an ensemble averaging technique. The observations support the existence of these two fundamentally different regimes: weakly stable (turbulent) nights rapidly reach a steady state (within 2–3 h). In contrast, very stable nights reach a steady state much later after a transition period (2–6 h). During this period turbulence is weak and nonstationary. To characterize the regime, a new parameter is introduced: the shear capacity. This parameter compares the actual shear after sunset with the minimum shear needed to sustain continuous turbulence. In turn, the minimum shear is dictated by the heat flux demand at the surface (net radiative cooling), so that the shear capacity combines flow information with knowledge of the boundary condition. It is shown that the shear capacity enables prediction of the flow regimes. The prognostic strength of this nondimensional parameter appears to outperform the traditional ones like the similarity parameter z/L and the gradient Richardson number Ri as a regime indicator.

AbstractWe derive new inequalities between the boundary capacity of an asymptotically flat 3-manifold with nonnegative scalar curvature and boundary quantities that relate to quasi-local mass; one relates to Brown–York mass and the other is new. We argue by recasting the setup to the study of mean-convex fill-ins with nonnegative scalar curvature and, in the process, we consider fill-ins with singular metrics, which may have independent interest. Among other things, our work yields new variational characterizations of Riemannian Schwarzschild manifolds and new comparison results for surfaces in them.

Despite the strategic importance of firms’ corporate political activity (CPA) and the efforts to study its different aspects, little has been researched about how firms can organise and manage their government affairs (GA) units more effectively. This thesis seeks to shed further light into this relevant aspect of CPA. Specifically, the focus of this thesis is on exploring how firms can design their GA units in ways to improve their ability to perform their information processing activities. To this end, this thesis relies on the case study methodology. The empirical focus is the GA unit working in large firms and its information processing activities as a boundary-spanning unit. This unit mediates the flow of information between its external political environment and the firms’ internal business units. Drawing on organisational design theory, this thesis contributes to CPA scholarship by exposing organisational antecedents of CPA. Ultimately, this thesis offers practitioners a set of mutually-reinforcing organizational mechanisms that can be put in place to improve the ability of their GA units to manage political information.

This study proposes a framework for measuring and explaining partnership formation and resilience. The motivation for this study is that we currently do not understand the precise mechanism by which partnerships form or how they stay together in the face of change. The framework draws on a design view of systems to argue that partnerships manage change through boundary spanning practices that operate on multiple levels of social reality. The literature suggests that there are many different types of boundary spanning practices. Some types foster social-technical innovations called "boundary objects" while others facilitate the progressive standardization of those practices through the comparison and selection of boundary objects by social actors who are themselves transformed by their adoption of these objects. The framework proposes a way to measure partnership capacity and social learning that corresponds to the orders of boundary spanning practices. It furthermore proposes three hypotheses, one concerned with partnership formation and two concerned with resilience. The first hypothesis states that partnerships form through a convergence of boundary spanning practices and a community of practice. Convergence depends on a host of factors, including the capacity of innovators and early adopters to leverage their early successes to build additional capital to further promote and eventually institutionalize their boundary spanning practices. The second hypothesis predicts that partnerships that demonstrate a pattern of alignment practices integrating operational and strategic concerns will tend to oscillate within a defined range of partnership functions or "states" (restricted resilience). The third hypothesis predicts that partnerships that inculcate a learning culture of institutional design practices will tend to persist under a theoretically limitless range of environmental demands (general resilience). To assess the framework, four case studies of water resource management partnerships in the Columbia River Basin were carried out. Data collection centered on interviews with boundary spanners, field trips, and secondary data. The results partially confirmed the first hypothesis, while evaluations of the resilience hypotheses were inconclusive. However, boundary spanning practices were catalogued according to the various types of partnership processes to demonstrate how the methodology can be used for cross-case comparisons and theory-building.

We investigate local properties of the Green function of the complement of a compact set E.
First we consider the case E ⊂ [0, 1] in the extended complex plane. We extend a result of V. Andrievskii which claims that if the Green function satisfies the Hölder1/2 condition locally at the origin, then the density of E at 0, in terms of logarithmic capacity, is the same as that of the whole interval [0, 1]. We give an integral estimate on the density in terms of the Green function, which also provides a necessary condition for the optimal smoothness. Then we extend the results to the case E ⊂ [−1, 1]. In this case the maximal smoothness of the Green function is H¨older-1 and a similar integral estimate and necessary condition hold as well.
In the second part of the paper we consider the case when E is a compact set in Rd , d > 2. We give a Wiener type characterization for the Hölder continuity of the Green function, thus extending a result of L. Carleson and V. Totik. The obtained density condition is necessary, and it is sufficient as well, provided E satisfies the cone condition. It is also shown that the Hölder condition for the Green function at a boundary point can be equivalently stated in terms of the equilibrium measure and the solution to the corresponding Dirichlet problem. The results solve a long standing open problem - raised by Maz’ja in the 1960’s - under the simple cone condition.

Purpose: to estimate the parameters of the processes of extraction of heavy metal ions from aqueous solutions. Object of study: processes of purification of natural and waste water from heavy metal ions. Subject of study: extraction of Cu2+, Pb2+, Zn2+, Cd2+, Ni2+ ions from aqueous solutions of different concentrations by adsorption, nanofiltration and ion exchange methods. The processes of removal of heavy metal ions from dilute solutions using magnetite sorbents, OPMN-P membrane and various types of cation exchange filters have been studied. It is shown that the efficiency of the process depends on the presence of hardness ions in water and pH at ion exchange purification, sorption time, initial concentration of metal ions in solution and pH at adsorption, as well as the choice of complexes in nanofiltration. The dependence of the selectivity of the nanofiltration membrane on heavy metals and rigidity ions on the type of complexing agent used was investigated.

The main objective of this thesis work was to gain understanding of the principles of biolubrication, focusing on synergistic effects between biolubricants. To this end surface force and friction measurements were carried out by means of Atomic Force Microscopy, using hydrophilic and hydrophobic model surfaces in salt solutions of high ionic strength (≈ 150 mM) in presence of different biolubricants. There was also a need to gain information on the adsorbed layers formed by the biolubricants. This was achieved by using a range of methods such as Atomic Force Microscopy PeakForce imaging, Quartz Crystal Microbalance with Dissipation, Dynamic Light Scattering and X-Ray Reflectometry. By combining data from these techniques, detailed information about the adsorbed layers could be obtained.The biolubricants that were chosen for investigation were a phospholipid, hyaluronan, lubricin, and cartilage oligomeric matrix protein (COMP) that all exist in the synovial joint area. First the lubrication ability of these components alone was investigated, and then focus was turned to two pairs that are known or assumed to associate in the synovial area. Of the biolubricants that were investigated, it was only the phospholipid 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) that was found to be an efficient lubricant on its own. Deposited DPPC bilayers on silica surfaces were found to be able to provide very low friction coefficients (≈ 0.01) up to high pressures, ≈ 50 MPa. A higher load bearing capacity was found for DPPC in the liquid crystalline state compared to in the gel state.The first synergy pair that was explored was DPPC and hyaluronan, that is known to associate on the cartilage surface, and we also noticed association between hyaluronan and DPPC vesicles as well as with adsorbed DPPC bilayers. By combining these two components a lubrication performance similar to that of DPPC alone could be achieved, even though the friction coefficient in presence of hyaluronan was found to be slightly higher. The synergy here is thus not in form of an increased performance, but rather that the presence of hyaluronan allows a large amount of the phospholipid lubricant to accumulate where it is needed, i.e. on the sliding surfaces.The other synergy pair was lubricin and COMP that recently has been shown to be co-localized on the cartilage surface, and thus suggested to associate with each other. Lubricin, as a single component, provided poor lubrication of PMMA surfaces, which we utilized as model hydrophobic surfaces. However, if COMP first was allowed to coat the surface, and then lubricin was added a low friction coefficient (≈ 0.03) was found. In this case the synergy arises from COMP facilitating strong anchoring of lubricin to the surface in conformations that provide good lubrication performance.Huvudsyftet med det här avhandlingsarbetet var att öka förståelsen för den låga friktion som finns i vissa biologiska system, med fokus på synergistiska effekter mellan de smörjande molekylerna. För detta ändamål studerades ytkrafter och friktion med hjälp av atomkraftsmikroskopi. Mätningarna utfördes med hydrofila och hydrofoba modellytor i lösningar med hög salthalt (≈ 150 mM) i närvaro av smörjande biomolekyler. Det var också nödvändigt att få information om de adsorberade skikten av biomolekyler. Det åstadkoms med hjälp av en rad tekniker så som AFM PeakForce avbildning, kvartskristallmikrovåg, dynamisk ljusspridning och röntgen reflektometri. Genom att kombinera data från dessa tekniker erhölls detaljerad information om de smörjande skikten.De smörjande biomolekyler som valdes ut för studierna var en fosfolipid, hyaluronan, lubricin, and cartilage oligomeric matrix protein (COMP) vilka alla finns i synovialledsområdet. Först undersöktes den smörjande förmågan hos dessa komponenter var för sig, och sedan fokuserade vi på två par av biomolekyler som man vet eller antar bildar associationsstrukturer i synovialleder. Av de enskilda biomolekyler som undersöktes var det endast fosfolipiden 1,2-dipalmitoyl-sn-glycero-3-fosfokoline (DPPC) som visade sig vara en effektivt smörjande molekyl. Deponerade biskikt av DPPC på silikaytor gav upphov till mycket låga friktionskoefficienter (≈ 0.01) upp till höga pålagda tryck, ≈ 50 MPa. DPPC bilager i flytande kristallin fas visade sig ha högre lastbärande förmåga än DPPC bilager i geltillstånd.Det första synergistiska par som undersöktes var DPPC och hyaluronan vilka man vet associerar på broskytan, och vi visade att hyaluronan associerar med såväl DPPC vesiklar som med DPPC bilager. Genom att kombinera dessa två komponenter uppmättes en smörjande förmåga som var jämförbar med den som DPPC ensam uppvisar. Även om friktionskoefficienten var något högre i närvaro av hyaluronan. Synergieffekten här består inte av en bättre smörjande förmåga, utan istället gör närvaron av hyaluronan att de smörjande fosfolipiderna kan ansamlas i stora mängder där de behövs, dvs. på de glidande ytorna.Det andra synergiparet var lubricin och COMP vilka nyligen har visats vara lokaliserade på samma platser på broskytan, vilket tyder på att de associerar med varandra. På egen hand var lubricins smörjande förmåga av PMMA, våra hydrofoba modellytor, dålig. Emellertid, om COMP först adsorberades på PMMA och sedan lubricin tillsattes uppmättes en låg friktionskoefficient (≈ 0.03). I det här fallet består synergin av att COMP möjliggör en stark inbindning till ytan av lubricin i konformationer som ger god smörjande förmåga.

Alors que les relations formelles entre organisations comme les alliances ont été largement étudiées, les relations inter-organisationnelles informelles demandent à être mieux comprises. Comment l'organisation gère-t-elle ses relations inter-organisationnelles informelles ? Quels sont les effets de ces relations sur l'entreprise ? Comment peut-on essayer d'organiser d'une façon consciente des actions d'influence de l'environnement au travers de ces relations ? Pour aborder ces questions, nous avons choisi d'utiliser le cadre de la théorie des capacités dynamiques, qui accorde une place importante aux relations entre l'entreprise et son environnement. Les capacités dynamiques de l'entreprise peuvent être définies comme la capacité à détecter et façonner des opportunités et des menaces, à saisir des opportunités, et à reconfigurer les ressources de la firme. Répondant à l'appel des chercheurs sur les capacités dynamiques, cette thèse analyse les micro-fondations de ces capacités. Notre étude s'appuie sur une analyse des individus "passeurs de frontières" qui participent aux relations inter-organisationnelles informelles au nom de leur entreprise. Nos travaux pointent les contributions des passeurs de frontières aux capacités dynamiques de l'entreprise et conceptualisent la capacité à gérer des relations inter-organisationnelles informelles comme capacité dynamiqueWhereas formal relations such as alliances have been well-studied, informal inter-organizational relations still need to be analyzed. This gap in the literature leads to the following research questions: How do organizations manage their informal inter-organizational relations? What are the effects of such relations? How can firms organize influencing activities based on these relations? The theory of dynamic capabilities addresses relations between the firm and its environment. The dynamic capabilities of the firm can be defined as the capacity of the firm to sense and shape opportunities and threats, to seize opportunities and to reconfigure assets. They permit the organization to adapt to and to shape its environment. This work contributes to answering the call from researchers to analyze the microfoundations of dynamic capabilities. It studies the role played by boundary spanners, individuals playing an interfacing role between the firm and its environment, in the dynamic capabilities of the firm. Further, this research leads to the conceptualization of the capacity to manage informal interorganizational relations as a dynamic capability allowing the firm to develop its absorptive capacity, legitimacy and influence on its environment

Three mathematical models, two of primary alkaline battery cathode discharge, and one of primary alkaline battery discharge, are developed, presented, solved and investigated in this thesis. The primary aim of this work is to improve our understanding of the complex, interrelated and nonlinear processes that occur within primary alkaline batteries during discharge. We use perturbation techniques and Laplace transforms to analyse and simplify an existing model of primary alkaline battery cathode under galvanostatic discharge. The process highlights key phenomena, and removes those phenomena that have very little effect on discharge from the model. We find that electrolyte variation within Electrolytic Manganese Dioxide (EMD) particles is negligible, but proton diffusion within EMD crystals is important. The simplification process results in a significant reduction in the number of model equations, and greatly decreases the computational overhead of the numerical simulation software. In addition, the model results based on this simplified framework compare well with available experimental data. The second model of the primary alkaline battery cathode discharge simulates step potential electrochemical spectroscopy discharges, and is used to improve our understanding of the multi-reaction nature of the reduction of EMD. We find that a single-reaction framework is able to simulate multi-reaction behaviour through the use of a nonlinear ion-ion interaction term. The third model simulates the full primary alkaline battery system, and accounts for the precipitation of zinc oxide within the separator (and other regions), and subsequent internal short circuit through this phase. It was found that an internal short circuit is created at the beginning of discharge, and this self-discharge may be exacerbated by discharging the cell intermittently. We find that using a thicker separator paper is a very effective way of minimising self-discharge behaviour. The equations describing the three models are solved numerically in MATLABR, using three pieces of numerical simulation software. They provide a flexible and powerful set of primary alkaline battery discharge prediction tools, that leverage the simplified model framework, allowing them to be easily run on a desktop PC.

Boundary Spanners of Humanity tackles the growing severity of global problems and our strained ability to collaborate by critically re-examining two pivotal tools: communication and public diplomacy. R. S. Zaharna, a leading scholar of public diplomacy and international strategic communication, exposes the limitations of intercultural communication and state-based public diplomacy and proposes a pan-human vision of communication that can revolutionize how we communicate globally. The book reveals how dominant views of communication and public diplomacy are based on a 19th-century mindset of separateness that clashes with today’s global connectivity and human diversity. In a radical break from outdated models that divide humanity into cultural categories, Zaharna introduces a vision of humanity-centered public diplomacy featuring three complementary logics of communication. Used together, these communication logics are key to leveraging diversity, navigating connectivity, and enhancing our capacity for global collaboration. Zaharna’s innovative approach stems from decades-long, interdisciplinary research spanning ancient cosmologies, diverse intellectual heritages, contemporary social science, and emerging neuro-biological science. Boundary Spanners of Humanity provides a rich array of examples from ancient diplomacies to the Covid-19 pandemic to illustrate a vision of pan-human communication that spans our diversity and harnesses it as an essential strength in collective problem solving and global collaboration.

In this chapter, the generalized or weak interpretation of the Dirichlet and Neumann problems for general elliptic expressions is motivated and then the Lax–Milgram Theorem is used to set the problems in the framework of eigenvalue problems for operators acting in Hilbert space. Results on variational inequalities in Chapter IV are applied to establish Stampacchia’s weak maximum principle, and this leads to the notion of capacity.

The roots of biological autonomy and health are the same. Goals make biology distinct as a science, for without goals, we cannot understand why a biological trait exists. Organisms are autonomous biological entities because they define what is inside and what is outside themselves. This boundary between inner and outer gives the organism a self-referential purpose. Claude Bernard made experimental physiology possible with his concept of the internal environment, but he was unable to explain how the organism established the boundary between itself and its environment. Hence, homeostasis portrays the organism as reactive not active. Autopoiesis is an alternative defining characteristic of living beings. It generates biological autonomy through additional biological constraint on chemical processes, not through a special vital force. Healthy organisms can construct their own environmental niche.

This chapter examines how historical institutionalism has influenced the analysis of welfare state and labor market policies in the rich industrial democracies. Using Lakatos’s concept of the “scientific research program” as a heuristic, the authors explore the development and expansion of historical institutionalism as a predominant approach in welfare state research. Focusing on this tradition’s strong core of actors (academic path- and boundary-setters), rules (methodology and methods), and norms (ontological and epistemological assumptions), they strive to demarcate the terrain of HI within studies of the welfare state, and to reveal the capacity of HI in this field to underpin a robust but flexible and enduring scholarly research program.

This book traces the corrosive effects of the revolving door between public service and private enrichment on the French state and its ability to govern and regulate the private sector. Casting a piercing light on this circulation of influence among corporate lawyers and others in the French power elite, the book analyzes how this dynamic, a feature of all Western democracies, has developed in concert with the rise of neoliberalism over the past three decades. Based on interviews with dozens of public officials in France and a unique biographical database of more than 200 civil-servants-turned-corporate-lawyers, the book explores how the always blurred boundary between public service and private interests has been critically compromised, enabling the transformation of the regulatory state into either an ineffectual bystander or an active collaborator in the privatization of public welfare. The cumulative effect of these developments, the authors reveal, undermines democratic citizenship and the capacity to imagine the public good.

The paucity of improvisation over the last 150 years of western art music is an anomaly. This chapter discusses why and how classical musicians today might incorporate more improvisation into their practice and performance. Examples from professional musicians demonstrate innovative approaches to classical improvisation as well as methods for renewing historical practices in modern contexts. As a developmental tool, improvisation can be used to deepen understanding of traditional repertoire, improve technique and aural skills, expand expressive possibilities, discover a personal voice, and lessen performance anxiety. Methods for increasing improvisation in public performance are also illustrated, including the preparation of improvised cadenzas in canonical repertoire, the exploration of multiple possible score interpretations, the practice of functional improvisation for church services, and the adventure of boundary-challenging creative acts. The chapter concludes by addressing challenges and constraints faced by potential improvisers in today’s classical music culture, especially in relation to education (when important enabling skill sets are left underdeveloped), career pressures (when deviations from convention are risky) and value systems (when improvisation is considered wrong and the creative capacity of performers is deemed inferior). Classical performers are encouraged to take some of their training into their own hands and assert their right for greater artistic autonomy.

In this book, Hubert Hermans, internationally known as the creator of the dialogical self theory, launches a new and original theory in which he links society with the most intimate regions of self and identity. The basic assumption is that the self is organized as an inner society that is simultaneously functioning as part of the society at large as exemplified by developments like self-sabotage, self-radicalization, self-cure, self-government, self-nationalization, and self-internationalization. The book makes even a more radical step. It not only deals with the societal organization of the self but also poses the challenging question whether the self is democratically organized. To what extent do the different self-parts (e.g. roles, emotions, imagined others) receive freedom of expression? To what extent are they treated as equal or equivalent components of the self? The question is posed how the self, in its organizing capacity, responds to the apparent tension between freedom and equality in both the self and society. The theory has far-reaching consequences for such divergent topics as leadership in the self; cultural diversity in the self; the relationship between reason and emotion; self-empathy;, cooperation and competition between self-parts; and the role of social power in prejudice, enemy image construction, and scapegoating. The volume concludes with a trailblazing discussion of cosmopolitan, deliberative, and agonistic models of democracy and their consequences for a democratically organized self in a boundary-crossing society.

Muslim American City studies how Muslim Americans test the boundaries of American pluralism as a model for secular inclusion. This ethnographic work focuses on the perspectives of both Muslims and non-Muslims in Hamtramck, Michigan, a small city situated within the larger metro Detroit region that has one of the highest concentrations of Muslim residents of any US city. Once famous as a center of Polish American life, Hamtramck’s now has a population that is at least 40 percent Muslim. Drawing attention to Muslim American expressions of religious and cultural identity in civic life—particularly in response to discrimination and gender stereotyping—the book questions the popular assumption that the religiosity of Muslim minorities hinders their capacity for full citizenship in secular societies, a viewpoint that has long played into hackneyed arguments about the supposed incompatibility between Islam and democracy. The study approaches the incorporation of Yemeni, Bangladeshi, and African American Muslim groups in Hamtramck as a social, spatial, and material process that also involves well-established Polish Catholic, African American Christian, and other non-Muslim Hamtramck residents. Extending theory on group identity, boundary formation, gender, and space-making, the book examines how Hamtramck residents mutually reconfigure symbolic divides in public debates and everyday exchanges, including and excluding others based on moral identifications or distinctions across race, ethnicity, and religion. The various negotiations of public space examined in this text advance the book’s main argument: that Muslim and non-Muslim co-residents expand the boundaries of belonging together, by engaging in social and material exchanges across lines of difference.

AbstractI show that the First Cause is not a series of changes (= events) describable by physical laws; rather, it is initially changeless and brought about the first event with the physical laws. It is distinct from the physical universe which is constantly changing according to quantum physics, and which does not have ‘the capacity to be the originator of an event in a way that is un-determined by prior event, and the capacity to prevent itself from changing’, which a First Cause must have. Thus, the First Cause cannot be part of the physical universe as postulated by Hawking’s no boundary proposal, which in any case is unproven and scientifically flawed. Rather, the First Cause is uncaused, beginningless, initially changeless, has libertarian freedom, and is enormously powerful, that is, a transcendent immaterial Creator. I reply to Thomistic objections and show that the conclusion of the Kalām Cosmological Argument (KCA) and the doctrine of creatio ex nihilo are consistent with both relational and substantival views of time, and with dynamic and static theories of time, and with both Craig’s Hybrid view (the First Cause is timeless sans creation and in time with creation) and the view of the Oxford School, both of which are defensible.

Abstract In Tanzania studies on conflicts between subsistence farmers and agropastoralists/pastoralists as well communities versus conservationists have been frequently reported. These include studies on water use conflicts in the Pangan River Basin. Agropastoralists have also been evicted as a result of these conflicts. The overriding tendency has thus been centered on discussion about what keeps pastoralists and crop cultivators apart rather than what keeps them together. Although conflicts occur mainly as a result of resource competition, some conflicts constitute only one aspect of a much more complex interaction between the two groups. Little has been documented in examining the relative contribution of climatic and non-climatic factors in aggravating these conflicts and how this triggers various dimensions of conflicts among livelihood groups. This study examined the relative contribution of climatic and non-climatic factors as causes of natural resource conflict, based on a study conducted in Kilosa and Kilombero districts in south-central Tanzania. The study further examined conflict resolution mechanisms in terms of adaptive capacity to address these issues in a changing climate and in particular explored the roles of institutions in conflict resolution, and the associated challenges and opportunities involved. The study was conducted through a household survey, focus group discussions and expert interviews with Kilosa and Kilombero district land planning officers. The aim was to understand the challenges of land use planning and how those transformed into conflicts between users. The results of the interviews in the two districts revealed that there were land conflicts related to boundary disputes between and among villages, investors against villages or communities, and government agencies versus villages or investors. Unlike Kilosa, Kilombero District had more land conflicts involving villages and government institutions. There is a complicated land conflict in 25 villages against the Ramsar site area.

Abstract The restoring forces on membranes are due to the applied tension, while the restoring forces for plates are due to the flexural rigidity of the plate’s material. The transition to two dimensions introduces some features that did not show up in our analysis of one-dimensional vibrating systems. Instead of applying boundary conditions at one or two points, those constraints will have to be applied along a line or a curve. In this way, incorporation of the boundary condition is linked inexorably to the choice of coordinate systems used to describe the resultant normal mode shape functions. For two-dimensional vibrators, two indices are required to specify the frequency of a normal mode, fm,n, with the number of modes in a given frequency interval increasing in proportion to the center frequency of the interval, even though that interval remains a fixed frequency span. It is also possible that modes with different mode numbers might correspond to the same frequency of vibration, a situation that is designated as “modal degeneracy.” A membrane’s response to sound pressures provides the basis for broadband condenser microphone technology that produces signals related to the electrical properties of that capacitor and the charge stored on its plates.

Methods exist in today’s published literature which establish proximity to the ratchet boundary of a given load set by decomposing a cyclic load history into constant and cyclic components. Such methods operate by calculating the utilisation of yield capacity throughout the structure in response to the cyclic load. The remaining yield capacity is then available to support the constant load. In this paper, a hybrid procedure is described which uses established finite element techniques to obtain a stable response to the cyclic load component, followed by a limit load analysis based on the remaining yield capacity, to calculate the maximum primary load. This approach is particularly useful in conjunction with Fourier based cyclic procedures which, although capable of predicting the existence of a stable cyclic response, are not based on classical shakedown theory and are therefore unable to predict proximity to ratchet, unless a search procedure is used. The hybrid approach provides the combined benefit of an efficient cyclic response calculation scheme with a measure of proximity to the ratchet boundary. In this paper, the hybrid method is applied to the Bree case before application to a more complex thermo-mechanical transient, typical of nuclear power plant loading. The generation of interaction diagrams for both cases is considered.

The issue of wellhead fatigue has been given significant attention during recent years. The complexity of the wellhead system in terms of interactions betwe[en conductor (low pressure) and wellhead (high pressure) housings leads to various analysis methods being proposed to evaluate fatigue damage in the system. Most of the critical base material hotspots are located in the wellhead housing region where the loads start to distribute between the high- and low pressure housing and the load paths are highly complex varying for different input parameters. Due to this, detailed fatigue analyses are typically performed on a project to project basis for the same wellhead geometry. This paper proposes an approach that simplifies the analysis of the base material hotspots in the housings and makes it independent of where the specific type of the wellhead system is used. It is suggested to consider the housings of the wellhead system as one component with a single characteristic M-N curve, or a few M-N curves if complexity requires so. The M-N curve is a specialization of the standard S-N curves provided in rules and standards. They are generated by combining the calculated load-to-stress curve at a given hotspot with the applicable S-N curve. The load used as a reference is typically a cross-sectional moment at the top of high pressure housing. For these purposes 3D FE models have been developed for two principal wellhead types, rigid lock and non-rigid lock. The models are used to investigate the effect of different boundary conditions and applied loading on M-N curves for each hotspot analysed. Sensitivity studies have been performed for several parameters that are considered important in wellhead fatigue analysis. Based on the sensitivity studies, the effect of each parameter on typical base material hotspots is presented. This paper provides estimates for the spread in the M-N curves for each individual base material hotspot in the wellhead housings. Results indicate that a single characteristic M-N curve per wellhead system type can be selected to represent the wellhead housings. In addition, based on results from the analyses carried out, recommendations regarding generalized boundary conditions to obtain a characteristic M-N curve for a specific wellhead type have been given.

As significant fluid machinery, canned motor pumps are widely applied in industrial field. The typical characteristic of canned motor pump is that the fluid comes into the narrow gap and affects the performance of canned motor. The coolant flow in the narrow annular gap between rotor and stator cans belongs to Taylor-Couette-Poiseuille flow which has been investigated for a long time while the thermal design is a key function of internal narrow gap annular flow of canned motor. However, the temperature distribution prediction of canned motor deviates from the experiments, especially in the high-capacity canned motor due to the large shear rate of fluid and eddy-current loss of motor’s can. According to the researcher’s work, the significant work lies in the heat transfer coefficient that different researchers give various numerical prediction and experimental measurement. It brings big challenge in thermal design of high-capacity canned motor pump. In this paper, the author focuses on the reason why the heat transfer coefficient is remarkably lower than that other’s forecast. In this paper, the heat transfer behavior of the boundary layer near surfaces in the annular flow is investigated by using the commercial fluid dynamic (CFD) method. Firstly, the Naiver-Stocks (N-S) equations and energy conservation equation are employed for modeling the flow and heat transfer behavior, and the k-ω turbulent model is used for solving the flow control equations. Secondly, the fluid domain is described by a simplified geometrical model: two concentric cylinders with finite gap length. Thirdly, numerical approach is used to analyze the subject with tools of Solidworks, ICEM CFD and Ansys Fluent. Two parameters are analyzed in the research, namely the rotating speed and the wall heat flux, without considering the fluid viscous dissipation and thermal contact resistance. Numerical simulation results indicate that Taylor vortex exists in the flow regime, and the temperature distribution is affected by both the rotating speed and the wall heat flux, named thermal barrier effect under large heat flux condition. The thermal barrier effect lies in that the temperature gradient of interface decreases compared to the peak value of temperature gradient near the surface, so that the heat transfer coefficient is reduced remarkably. This effect leads to the temperature prediction deviates from the experiment measurement.

Carbon nanotubes (CNTs) have been thoroughly documented to demonstrate superior heat transfer properties. It has also been determined that these properties decrease substantially as overall dimensions increase from the nanoscale to the microscale. Using non-equilibrium molecular dynamics simulations and finite element analysis, the influence of both internal and external thermal boundary resistance effects on the thermal conductivity and specific heat capacity of single walled carbon nanotube bundles were investigated. Comparisons were made between accepted property values for single CNTs and for CNT bundles. Also, energy transfer between varying sized bundles of single-walled carbon nanotubes (SWCNTs) and a surrounding pressure-driven Lennard-Jones (LJ) fluid were calculated.

Boundary layer suction is used in turbomachinery to control flow separation to enhance the loading capacity of a compressor. This paper focuses on both numerical calculation and experimental investigation with boundary layer suction holes made in the suction surface of a compressor cascade with a large camber angle. Experimental and numerical investigations are carried out with suction holes in different positions. In the experimental investigation, exit aerodynamic parameters are measured using a five-hole aerodynamic probe, and ink-trace flow visualization is adopted on cascade surface. Experimental and numerical results indicate that both side and middle suctions on the suction surface can efficiently remove low-energy fluid to increase the cascade load capacity while they effectively restrain the corner flow separation. The cascade aerodynamic performance is obviously improved by middle and side suctions, and it is also significantly altered by the position of suction changes. The middle suction holes have their best positions at about 60–66% chord length from the leading edge, and the side suction holes have their best positions a little downstream the corner separation line.

In this paper an analytical method and a PDE-based solution to control temperature distribution in FGM plates is introduced. For the rectangular FGM plate under consideration, it is assumed that the material properties such as thermal conductivity, density, and specific heat capacity, vary in the width direction (y); and the governing heat conduction equation of the plate is a second-order partial differential equation. Since there has been little control synthesis work for PDE-based systems as compared to the abundance of control design techniques available for ordinary differential equations (ODEs), most of the proposed control approaches for continuous domain rely on discretizing the PDE model into a set of ODEs. Using Lyapunov’s theorem, we will show that with applying controlled heat flux through the boundary of the domain, the temperature distribution of the plate will approach to the desired distribution of Td (x, y). Finally, numerical methods are used to analyze transient heat transfer as distributed temperature T (x, y, t) converge to desired one of Td (x, y).

Most of the hydraulic steel structures (HSS) in the U.S. have reached or have past their design life, which leads to unsatisfactory performance. Welded connections with low fatigue resistance, poor weld quality, unanticipated structural behavior, or unexpected loading due to the deterioration of the design boundary conditions are the causes of fatigue cracking. The purpose of this report is to identify and evaluate the traditional and new methods used for fatigue and fracture repairs in navigation steel structures to restore their load carrying capacity and fatigue and fracture resistance. The final objective was to generate a guidance report comprising of recommended and more efficient repair methods for the different fatigue limit states observed in navigation steel structures.
