We consider the dilute regime of active suspensions of liquid crystalline polymers (LCPs), addressing issues motivated by our kinetic model and simulations in Forest et al. (Forest et al. 2013 Soft Matter 9 , 5207–5222 ( doi:10.1039/c3sm27736d )). In particular, we report unsteady two-dimensional heterogeneous flow-orientation attractors for pusher nanorod swimmers at dilute concentrations where passive LCP equilibria are isotropic. These numerical limit cycles are analogous to longwave (homogeneous) tumbling and kayaking limit cycles and two-dimensional heterogeneous unsteady attractors of passive LCPs in weak imposed shear, yet these states arise exclusively at semi-dilute concentrations where stable equilibria are nematic. The results in Forest et al. mentioned above compel two studies in the dilute regime that complement recent work of Saintillan & Shelley (Saintillan & Shelley 2013 C. R. Physique 14 , 497–517 ( doi:10.1016/j.crhy.2013.04.001 )): linearized stability analysis of the isotropic state for nanorod pushers and pullers; and an analytical–numerical study of weakly and strongly sheared active polar nanorod suspensions to capture how particle-scale activation affects shear rheology. We find that weakly sheared dilute puller versus pusher suspensions exhibit steady versus unsteady responses, shear thickening versus thinning and positive versus negative first normal stress differences. These results further establish how sheared dilute nanorod pusher suspensions exhibit many of the characteristic features of sheared semi-dilute passive nanorod suspensions.

Prediction of ship’s total resistance of a pusher-barge system has become enormous complexity involving nonlinear-hydrodynamic flows behaviour along their hull forms. Both of empirical and simplified numerical solutions may still lead into inaccurate results due to presence of nonlinear characteristics of the pressure and viscous resistances. The use of a more sophisticated method would obviously necessitate to solve the above problem. This paper presents a Computational Fluid Dynamics (CFD) approach to predict the total ship’s resistance of a pusher-barge system at various barge’s configurations. To achieve such objective, four different configurations of the barge models incorporated with various Froude numbers have been taken into account in the computational simulation. In general, the results revealed that the increase of Froude number (Fr = 0.182 to 0.312) was proportional to the magnitude of RT, RP and RV. Regardless of the various Froude number, the pusher-barge system with a 13BP configuration provides the highest resistance compared to the 12BP and 11BP. In addition, the arrangement of barges in the longitudinal (12BP) and lateral (21BP) configurations produced a significant effect with increases in RT, RP and RV values of 110%, 167.5% and 77.6%, respectively. The possible reason for this is that the increase of the total wetted surface area for 21BP has produced to a proportionally higher amount of the pressure and viscous resistance. Overall study, the numerical results were presented and analysed based on few aspects involved the total resistance and resistance coefficient in terms of pressure and viscous resistance of the pusher-barge system. This analysis provides very valuable information on choosing the most reliable arrangement of pusher-barge system.

Reheating of steel slabs for further processing such as hot rolling usually takes place in gas-fired pusher furnaces. Temperatures well above 1000°C, combined with an atmosphere containing H2O, CO2, and O2, lead to substantial oxidation of most steel grades. Newly developed advanced steels often contain significant amounts of Si. This element plays a dominant role in the scaling behaviour near the steel-scale-interface, since fayalite (Fe2SiO4) forms a eutectic with wuestite (Fe1–xO) that melts as low as 1177°C.To better understand the high temperature oxidation behaviour, lab-scale trials were performed with different steel grades containing up to 3 wt.% Si. Possible interactions of Si with other alloying elements present in the samples such as Cr, Mn and Al were also of interest. The atmosphere contained 20% H2O, 7% CO2, and 3% O2, resembling reheating conditions in pusher furnaces, and temperatures ranged from 1100 to 1240°C. For metallographic investigation, the oxidised samples were cold mounted under vacuum using taper section angles. After preparation, the sections were examined through light microscopy, SEM/EDS, XRD, and TEM. The local distribution of the alloying elements could be mapped efficiently, and phase identification was successful in most parts. Under the applied experimental conditions, the elements of interest were present in their oxidic form either as pure or as mixed oxides. Higher Si-contents led to an increased build-up of eutectic melting phase at the steel-scale-interface at temperatures above 1177°C, which in turn further accelerated the oxidation.

The aim of the current research program was to investigate the social context of escalation in response to continued pushy behaviour in the workplace. In doing so, this research program contributes to the development of communication skills by investigating the entire context of skills required for effective communication in managing everyday conflict in the workplace. The response class, Responding to continued pushy or dominating behaviour in the workplace, was selected as a vehicle for examining the context of escalation for two reasons. Firstly, this response class, by the very nature of pushy behaviour, embodies a continued interaction. In the past, assertive communication research has focused on one off responses rather than a continued interaction. Secondly, this response class has been identified in previous research as being of interest to assertiveness trainees (Cooley, 1979, Lefevre & West, 1984, Wilson & Gallios, 1993). The theoretical premise of the current research program resides in the application of Social Rules Theory to the difficult face-to-face communication situation, or response class, of responding to continued pushy behaviour in the workplace. In doing so, this approach also takes into account dialectical theory, conflict resolution theory, and the concept of response components that can be selected and/or combined in order to meet the requirements, or rules, of a specific situation. In adopting the Social Rules approach, the current research program addresses the key criticisms of the traditional approach to assertion and assertion training, namely that people behaving assertively are sometimes negatively evaluated for assertive behaviour (Wilson & Gallois, 1993); and that assertion traditionally focused on the expressiveness of a response at the unintended cost of social or contextual appropriateness (Crawford, 1988); that finding a response is assertive does not delineate which aspects of the response are producing which types of effects (Galassi, 1978; Mullinix & Galassi, 1981). Most importantly, the current research contributes to the field by examining the negative response class in terms of a response sequence of escalation, rather than a one-off response. This is new research and contributes to the field theoretically and to the conceptualisation of assertion and communication. In order to meet the goals of the current research program, the response class Responding to continued pushy behaviour in the workplace, was defined precisely in terms of the situational context. This response class implies a workplace relationship of an ongoing nature. Four other variables were involved in defining and investigating the situation. These were status, gender of message sender, gender of message receiver, and response level (initial response, first escalation or second escalation). The current program of research was carried out in a series of three related studies, and these four variables were examined in each of the three studies. The purpose of the first study was to elicit social rules and goals for interpersonally effective and appropriate escalation strategies in response to pushy dominating communication in the workplace. This study was conducted in two parts, a qualitative questionnaire completed by 20 females and 20 males, and two focus groups, one for females and one for males. Content analysis revealed a set of rules for an escalation sequence for each combination of status and gender. These rules were then operationalized, filmed and analysed in the second study. One hundred and twenty-three participants (64 females and 59 males) with work experience watched the operationalized responses and rated them on a series of seven scales. These scales were effectiveness in stopping the pushy behaviour (task effectiveness), effectiveness in maintaining the relationship (maintenance effectives), social appropriateness, interpersonal skill required, risk involved, personal difficulty in making the response, and likelihood of making the response. Analyses included descriptive statistics, which indicated that the operationalized responses were perceived to be effective and socially appropriate. Multivariate Analysis of Variance (MANOVA) were also conducted and revealed a number of significant interactions for each status level (manager, colleague, subordinate). The third and final study in this research program adopted a qualitative approach to examine continued pushy or dominating communication in the workplace. Eighty-two (45 female and 37 male) participants completed a qualitative questionnaire utilizing an open-ended approach. This questionnaire was designed for the purpose of the third study to elicit the typical behaviours, emotions and cognitions participants have in response to continued pushy behaviour in the workplace. Also, a data analysis process was designed specifically for the third study to provide an analytical procedure that was as systematically rigorous and replicable as possible. This process is explained in detail in Study 3. The results of the third study revealed differences between actual behaviour and rule based behaviour in response to continued pushy behaviour, namely that actual responses are more public and direct in nature, and more likely to promote destructive conflict escalation. This finding implies that typical responses are not as effective as rule based responses, highlighting the benefits of applying social rules to manage difficult face to face communication situations. In summary, the current research project utilized a multi-method approach in a series of three studies to reveal the nature of Social Rules based responses and typical responses. The results of this research program have implications for both the theory and practice of effective communication and effective communication training. Evaluation of both social rules based and typical responses have implications for communication trainees who wish to make informed choice based on a consideration of functionally effective behaviour and personal satisfaction. For example, social rules for escalation in response to continued pushy behaviour from a male manager may indicate that it is most effective for a female subordinate to acquiesce. However, the female subordinate may choose to violate social rules and risk being perceived as inappropriate and damaging the relationship, to achieve a super-ordinate goal or for personal satisfaction. Conversely, the social rules and responses developed in the current research program have implications for professional effectiveness in the workplace by providing guidelines for dealing with dominating behaviour.

La presente tesi tratta il comportamento meccanico delle fasce di piano in muratura composite. Con tale termine ci si riferisce alle fasce di piano che hanno al di sotto un elemento portante in conglomerato cementizio armato, come ad esempio cordoli o solai. Assieme ai maschi murari, le fasce di piano costituiscono gli elementi portanti di una parete in muratura. Tuttavia, in caso di analisi sismica di un edificio in muratura, l’effetto fornito da tali elementi è trascurato e si considera solamente il contributo dei maschi murari. Ciò è dovuto anche alla scarsa conoscenza che ancora oggi si possiede sul loro comportamento meccanico. Per questo motivo diversi gruppi di ricerca tutt’ora sono impegnati in tale studio. In particolare, il lavoro di questa tesi, s’inserisce nel più ampio progetto di ricerca condotto dalla professoressa Katrin Beyer, direttrice del Laboratorio di Ingegneria Sismica e Dinamica Strutturale del Politecnico di Losanna (Svizzera).

This thesis investigates the torsional performance of steel structures with and without rigid diaphragm constraints through numerical simulations and evaluates the appropriateness of relevant design provisions in current seismic design codes. In the first part of the work, six theme structures with different (1) in-plane stiffness of diaphragm, and (2) horizontal configurations of vertical braced frames were designed and their performance evaluated through both nonlinear static and dynamic analyses. Comparisons of the analytical results between the structures with and without rigid diaphragm constraints indicate that the in-plane rigidity of the diaphragms affects the efficiency of in-plane force transfer mechanisms, resulting in different global ductility and strength demands. Rigid diaphragm structures exhibit higher global strengths as well as higher torsional rotation capacity because of the infinite in-plane stiffness of the diaphragm. Semi-rigid diaphragm structures have higher ductility demands due to the finite in-plane diaphragm stiffness. The inclusion of bi-axial forces in the analyses reduces the structural strength and increases the ductility demands on the peripheral frames. The axial forces in the collectors and chords that make up the diaphragm depend on (1) the sequence of brace buckling and (2) vertical configuration of the braced frames. The results show higher axial forces in collectors in the roof diaphragms, and higher chord axial forces in the third floor diaphragms. The shear connections in the beams that make up both the collectors and chords are susceptible to failure due to the significant increment of axial forces in those members. The conventional beam analogy used in design can severely underestimate the axial forces in chords and collectors when the structures step into the inelastic stage.

The research presented in this thesis is to evaluate the feasibility of demountable shear connectors as an alternative to welded shear connectors in composite structures through push off tests and composite beam tests. Push off tests were conducted to examine the shear strength, stiffness and ductility of demountable shear connectors in composite structures. The experimental results showed that demountable shear connectors in composite structures have very similar shear capacity to welded shear connectors. The shear capacity was compared against the prediction methods used for the welded shear connections given in Eurocode 4 and AISC 360-10 and the methods used for bolted connections in Eurocode 3 and ACI 318-08. It was found that the AISC 360-10 and ACI 318-08 methods overestimated the shear capacity in some cases. The Eurocode method is conservative and can be utilised to predict the shear capacity of demountable connectors in composite structures. The experimental studies of two identical composite beams using demountable shear connectors and welded shear connectors showed very similar moment capacity. However, the specimen with demountable shear connectors was more ductile compared to the welded specimen. The experimental study suggests that the methods available in Eurocode 4 and BS 5950 for predicting moment capacity and mid span deflection can be adopted for composite beam with demountable shear connectors. In addition, a finite element analysis of push off test and beam test with demountable shear connectors was also conducted for parametric studies and results are used to evaluate the behaviour of composite structures.

The behavior and strength of welded shear studs are subjects of ongoing study. In recent years, research has shown that the American Institute of Steel Construction (AISC) specification equations for shear stud strength are unconservative for studs placed in deck with ribs transverse to the steel beam. Twenty-four solid slab push-out tests, 93 composite slab push-out tests, and bare stud tests were performed to study the effects on stud strength of friction, normal load, position of studs in the ribs of steel deck, concrete strength, and stud properties. Stud diameters ranged from 3/8 in. to 7/8 in., deck heights ranged from 2 in. to 6 in., and both single and pairs of studs were tested. The push-out test results from this study were combined with other studies to propose a new stud strength prediction model. Three new beam tests were performed to study the effect of the stud position in the ribs of the steel deck. The results of these tests, along with 61 other beam tests, were used to verify the new stud strength prediction model. A reliability study was performed to determine resistance factors for stud strength and beam strength.

The main inquiry for this research is to identify the reasons that contribute to customer switching intention decisions. In addressing this enquiry, two theories - the theory of migration and theory of planned behaviour - were identified as the theoretical framework underpinning the study. Two main objectives of the study were (i) to identify the push-pull and mooring factors and (ii) to measure the relationship between the push-pull and mooring factors towards switching intention. The investigation focused on the impact of with push-pull-mooring factors on switching intention. Early research into switching behaviour studies focused largely on variables that contribute to the switching intention decision, mainly due to the critical incidents encountered by customers that push them from their origin or pull them to another destination or mooring factors that might inhibit or mitigate their switching decision. In view of this, a combination of push-pull and mooring variables were used to measure the switching intention behaviour. A multiple method approach was used to study the issues in two different stages. In the first stage qualitative data collection was used to support and confirm the identification of factors from the literature. For the main quantitative methods, using a hypothetical deductive testing approach, this study (N=2018) used survey data collected via a self-administered, voluntary online survey, to develop switching intention behaviour model. The results indicated that situational factors, positive attachments, perceived switching benefits, positive attitudes towards switching and positive beliefs of others towards switching emerged as consistent push factor while availability of alternatives emerged as the pull factors. Interestingly poor pricing, poor service incidents, positive ability to switch and switching barriers were not supported in this study indicating that there is no relationship between poor pricing, poor service incidents, positive ability to switch and switching barriers towards switching intention.

Com um questionário online, foram coletados de 265 respostas, que foram tratadas com procedimentos estatísticos, como análise descritiva, multivariada e de cluster. As descobertas confirmam que os clientes que receberam notificações push têm uma média superior nos gastos mensais nos supermercados, em comparação com os clientes com aplicativos de marca que não receberam nenhuma notificação push. Entretanto, esses resultados foram observados apenas nos compradores envolvidos profundamente em todos os atributos da compra e nos compradores com uma maior preocupação com os produtos. Academicamente, esta dissertação contribui para a discussão sobre notificações push como um canal de marketing direto e sobre os efeitos das características do cliente no efeito do marketing direto. Essa investigação também oferece informações para o profissional de marketing, afirmando que as notificações por push podem ser usadas para impulsionar compras offline dos usuários.
Mobile adoption has seen an exponential increase worldwide in recent years, which has also been reflected in the number of mobile applications, or apps. Many companies have developed their own apps to display their brand entities and have started using them as a direct marketing channel with push notifications, messages displayed on their mobile device screen. This research seeks to understand the extent of the impact on purchasing behavior of push notifications sent by branded applications from Portuguese supermarket chains. It also aims to segment the results to different buyer groups based on psychographic variables. This research was conducted by adopting a quantitative approach and non-probabilistic sampling. With an online questionnaire, 265 responses were collected and treated with statistical procedures such as descriptive, multivariate and cluster analysis. The findings confirm that customers who received push notifications had a higher average monthly spend in supermarkets than customers with branded apps who received no push notifications. However, these results were observed only for buyers deeply involved in all attributes of the purchase and for buyers with a greater concern for the products. Academically, this dissertation contributes to the discussion of push notifications as a direct marketing channel and the effects of customer characteristics on the effect of direct marketing. This research also provides insight to the marketer, stating that push notifications can be used to drive users' offline purchases.

Manipulation of insect behavior can provide the foundation for effective strategies for control of insect crop pests. A detailed understanding of life cycles and the behavioral repertoires of insect pests is essential for development of this approach. A variety of strategies have been developed based on behavioral manipulation and include mass trapping, attract-and-kill, auto-dissemination, mating and host plant location disruption, and push-pull. Insight into application of these strategies for insect pests within Diptera, Lepidoptera, Coleoptera, and Hemiptera/Thysanoptera are provided, but first with an overview of economic damage and traditional control approaches, and overview of relevant behavioral/ecological traits. Then examples are provided of how these different control strategies are applied for each taxonomic group. The future of these approaches in the context of altered crop development for repellency or as anti-feedants, the effects of climate change and the risks of behaviorally-based methods are discussed.

Why does religion sometimes promote democracy and sometimes do just the opposite? Theology alone cannot explain the wide variety of influences religion has on democratic attitudes and behaviours. This book presents a theory of religion, group interest, and democracy. Focusing on communal religion, it demonstrates that the effect of communal prayer on support for democracy depends on the interests of the religious group in question. For members of groups who would benefit from democracy, communal prayer increases support for democratic institutions; for citizens whose groups would lose privileges in the event of democratic reforms, the opposite effect is present. Evidence from Lebanon, Iraq, and elsewhere supports these claims. Communal religion increases the salience of sectarian identity, and therefore pushes respondents' regime attitudes into closer alignment with the interests of their sect.

AbstractWe present a synthetic benchmarking framework that targets the systematic evaluation of RV tools for message-based concurrent systems. Our tool can emulate various load profiles via configuration. It provides a multi-faceted view of measurements that is conducive to a comprehensive assessment of the overhead induced by runtime monitoring. The tool is able to generate significant loads to reveal edge case behaviour that may only emerge when the monitoring system is pushed to its limit. We evaluate our framework in two ways. First, we conduct sanity checks to assess the precision of the measurement mechanisms used, the repeatability of the results obtained, and the veracity of the behaviour emulated by our synthetic benchmark. We then showcase the utility of the features offered by our tool in a two-part RV case study.

AbstractThis chapter explores the evolution of responsible sourcing in mineral supply chains, given the precedence of negative environmental, social, and economic rights that have been part of our global extractive history. It tracks the evolution of concepts of sustainability from a siloed approach to the trade-offs involved in weak and strong sustainability approaches. The chapter introduces the RE-SOURCING Project’s definition of Responsible Sourcing, based on four years of research and consultations. Taking a rights-based approach, it addresses the responsibilities of duty-bearers to the rights-holders. The definition reflects the societal need to change behaviours within mineral supply chains, requiring a halt to negative impacts but also stressing the need to create positive outcomes from operations. The challenges within environmental, social, economic, and governance landscapes are outlined, and the efforts to address these challenges are summarised. The chapter sets out the analytical framework, explored in greater depth in other chapters, addressing how the need to secure a sustainable future translated into a need for changing codes of behaviour in governance, supply chains, financial valuation, and engineering and production methods. A host of guidelines, standards, and legislation have pushed for changes in how the private and public sectors operate, contributing to securing a sustainable future.

This paper presents a real-time closed-loop rotorcraft simulation framework using HeliUM-A, a high-fidelity flight dynamics analysis, and a Simulink® -based flight control system model. Serial optimization and parallel computing techniques are introduced in HeliUM-A to achieve real-time speeds. A customized ordinary differential equation solver with parallel load balancing enables accelerated time marching simulations. Software interfaces are introduced to encapsulate HeliUM-A into a Level-2 S-function Simulink® block. Using standardized Simulink® ports, control inputs, rotor/body states and their time derivatives as well as relevant output quantities are communicated in-memory between Simulink® and HeliUM-A for closed-loop execution. This encapsulation retains the parallel computing improvements in HeliUM-A when executed through MATLAB, Simulink® or through the compiled executable automatically generated by the Simulink Coder. The framework is demonstrated on a coaxial compound scout helicopter with a pusher-propeller. Closed-loop vehicle and rotor responses are compared between two flight dynamics models: a stitched simulation model based on linearized models extracted from HeliUM-A, and the original HeliUM-A model. Time domain and frequency sweep comparisons showed excellent agreement between the stitched and nonlinear HeliUM-A models demonstrating that the new HeliUM-A based closed-loop framework shows expected behaviour. The HeliUM-A bare airframe model can be used to simulate various rotorcraft configurations in edge-of-the-envelope flight conditions, whereas the stitched models are accurate for center-of-the-envelope conditions.

Recent advances in state space modeling of the aerodynamic interactions between rotors in advanced coaxial configurations have allowed for increased understanding of the stability and controllability of such aircraft. However, modern aerodynamic analysis tools such as free wake models have shown that the behavior of the inflow of a coaxial configuration may not exhibit only first order behavior as some models suggest. Furthermore, it is clear that tip-path plane motion of a coaxial rotor can have an impact on the inflow behavior through wake distortion, and so the inflow response is likely higher order in nature. It is unclear what effects such behavior would have on the prediction of handling qualities and the design of control systems. The objective of this paper is to extend a system identification method to the extraction of a second order inflow representation capable of capturing from free-wake models all of the relevant dynamics of the wake, including wake distortion. This method has successfully been used to extract a first order representation of the inflow for both single main rotor helicopters and coaxial rotorcraft. With state-space models of inflow defined for an advanced coaxial configuration, this paper also presents a comparison of the fully-coupled aircraft flight dynamics, and the design of an explicit modeling-following feedback controller, with both the free-wake identified model and a momentum theory based approach.

This study investigates the transient response characteristics of a compound rotorcraft and seeks to establish methods of control that enhance handling qualities via the use of redundant control surfaces. Simulations of a hypothetical compound rotorcraft based on a UH-60A airframe and rotor compounded with a wing and pusher propeller are used. This study presents general background on the simulated compound rotorcraft model, the behavior of redundant controls in minimum power quasi-steady maneuvering flight, and then extends the analysis to focus on the transient response characteristics of the aircraft in various maneuvers. In addition to the four traditional controls, this study will examine the use of three redundant control effectors: propeller pitch, symmetric wing flap deflection, and differential wing flap deflection, which can be optimized for performance and handling qualities. Background material is presented for trim analysis of quasi-steady maneuvers to gain an understanding of the control allocation that minimizes power required in sustained maneuvers. The results of the optimization are incorporated into a g-command dynamic inversion controller to regulate longitudinal and vertical load factor in minimum power flight. Pull-up and turning maneuvers are simulated to analyze handling qualities both with and without redundant controls. Quickness metrics are investigated for pull-up and turning maneuvers to understand how the deployment of redundant controls might be used to enhance transient response and handling qualities.

Pushover analysis is performed to determine the capacity of jacket type offshore structures subjected to lateral loads. Overall behavior of the platform in the nonlinear range of deformation can be observed from pushover analysis results. This analysis can be used for the platform capacity assessment. For performing pushover analysis, nonlinear behavior of structural elements and lateral load pattern should be obtained. Both displacement and load control type of the analysis can be performed. One of the important aspects of pushover analysis is the non-linear behavior of the underlying soil and its interaction with the pile. In this paper pushover analysis of sample jacket type offshore platforms considering pile soil interaction (PSI) is performed. In the pushover analysis performed, fiber elements are used for the modeling of the member and soil nonlinearities. Actual soil layer properties, which have been derived from geotechnical reports, are incorporated in the model using fiber elements of “DRAIN-3DX” software. Each soil layer is presented by an equivalent fiber element, having the same characteristics of the relevant soil. The pile structure from top elevation until its tip together with other jacket components including the legs and braces are also introduced by fiber elements. Push over analysis is performed for the platforms subjected to wave load pattern. In order to compare the Pile-Soil Interaction (PSI) effects, all of the analyses are also performed using fixed and pinned pile ends at mud line elevation and pile stubs. The significance of the Pile-Soil Interaction and soil non-linear behavior is pointed out from this comparison and analysis results.

The non-periodical oscillation was reported in Water Column Oscillator, which simulates a passive safety system of a future nuclear reactor, however, the mechanism of the oscillation is not clarified. The objective of this study is to elucidate the mechanism of non-periodical oscillation in Water Column Oscillator experimentally and analytically. The U-type rectangular duct is filled with the water in a certain degree of height. An end of the duct is sealed and the other is open to the atmosphere. The electromagnetic valve is installed at the top of the sealed side. A cover gas simulating vapor generation by residual heat is injected constantly into the gas phase of the sealed side. The water column oscillation with its natural frequency continues until the free surface in the sealed side, pushed by the gas, reaches at a certain height. When the height of the water level reaches HL, the electromagnetic valve is open and the cover gas flows out from the U-type duct. The gas is ejected rapidly, and thus, the cover gas pressure decreases almost to the atmospheric pressure. The water level in the sealed side of the duct rises with water supply from the open side and reaches a certain height HU. Then the valve is closed again and the increasing gas pressure pushes down the water surface of the sealed side. The water level oscillates repeating the above process. The analytical model which agrees well with the experiment is derived. The bifurcation-like phenomenon is shown in experiment, however, it can be clear that the phenomenon is not bifurcation but noise effects by the numerical simulation with noise effects. The variation of characteristics of oscillation are investigated in detail by using Poincare´ section (Y2(N), U2(N)), which indicate cover gas pressure and water level velocity at the beginning of the Nth valve-open instant. The parameter region where the system shows bifurcation can be discovered by the numerical simulation. The bifurcation is confirmed in the experiment.

The aim of this investigation is to reveal the effect of size and strength of materials, pushing forces and so on. That we study in this report are as follows: (1) The effect of bending radius ratio on ovality of outer diameter and eccentricity of wall thickness, and (2) the effect of ratio of wall thickness to outer diameter on ovality of outer diameter and eccentricity of wall thickness. The conclusions of this study are summarized as follows. (1) The ovality of outer diameter and the eccentricity of wall thickness increase as the bending radius ratio decreases. (2) The ovality of outer diameter decreases and the eccentricity of wall thickness increase as thickness outside diameter ratio increases.

In this work several different obturator designs were explored for use with a four-petal, pushlaunch sabot design for a tungsten heavy alloy projectile. Stepped-top obturators resulted in higher average pitch values than flat-topped obturators. Single piece obturators of acetal or UHMWPE appeared to provide equivalent behavior; acetal appears to be more brittle than UHMWPE, but was easier to machine to tolerance. Two-part obturators functioned reliably and were less prone to result in secondary impact on targets. Aluminum and steel pusher plates offered comparable performance for the projectile and launch velocity considered. A Garolite G-11 composite pusher plate didn’t prove strong enough to function correctly. Shots with drag flares consistently had lower pitch values than shots without drag flares.

Jacket Type Offshore Platforms show nonlinear behaviors under strong ground motions result from nonlinear behaviors of soil, pile and jacket members. Nonlinear behavior study isn’t carried out accurately unless an accurate and suitable analytical method is selected. The main focus of this paper is the soil-pile-structure interaction analysis of the jacket type offshore platforms subjected to strong ground motion. A nonlinear dynamic analysis shows a true response if a logical model and an accurate theory are selected. In addition to nonlinear dynamic analysis, nonlinear static analysis is also carried out in this paper and results of the static nonlinear and dynamic nonlinear analyses have been compared. It was concluded that nonlinear static analysis can be used under some conditions instead of nonlinear dynamic analysis.

Earthquake disasters in the United States account for $6.1 billion of economic losses each year, much of which is directly linked to infrastructure damage. These natural disasters are unpredictable and represent one of the most difficult design problems regarding constructing resilient infrastructure. Structural floor and roof diaphragms act as the horizontal portion of the lateral force resisting system (LFRS), distributing the seismically derived inertial loads out from the heavy concrete slabs to the vertical LFRS. Concrete-filled steel deck diaphragms are ubiquitously used in steel construction worldwide due to the ease of construction and cost-effective use of material. This report first presents a series of concrete-filled steel deck push-out tests that explores the effect of cyclic loading on the strength of steel headed stud anchors. The effect that cyclic loading has on structural performance is explored across different concrete densities, steel headed stud anchor placements and groupings, steel deck orientations, and edge conditions. As compared to prior tests, the push-out tests conducted in this work included four rows of studs along the length rather than the typical two rows, and an ability to impose cyclic loading. This provided novel insight into force flows, failure mechanisms, and load distribution between studs and stud groups. Most of the specimens also used lightweight concrete, as is common in high seismic zones.Secondly, this report describes a full-scale experimental concrete-filled steel deck diaphragm specimen which explored the cyclic behavior and capacity of this structural system. This experiment builds on previously reported experimental studies. This specimen demonstrated force distribution and flows in an indeterminant floor system and captured realistic boundary conditions and construction practices that affect the performance of this system in building structures. The results showed that concrete-filled steel deck diaphragms fail as expected and may have significant overstrength. Furthermore, a finite element framework is presented that can simulate cyclic fracture through the use of a high-fidelity steel material model. This framework was used and validated against nine experimental push-out specimens tested and documented as part of this research. The simulation capacity provides an avenue to further investigate this structural system through simulated parametric study.

The attraction of young individuals from urban areas and university towns to non-metropolitan regions is an important source of economic growth for many regions. The review of young people's mobility behaviour in the early career stage in the Nordic countries highlights that migration decisions are influenced by a set of various push and pull factors, working simultaneously. It is important to understand the background of the mover, where the behavior of the mover is impacted by educational background and industrial specialisation, geographical origin, gender, income-level and civic status. Learning more about current migration drivers and migration aspirations of the early career cohorts in the Nordic countries will help policymakers to shape the future of Nordic labour markets and better prepare the future labour supply and demands in rural areas. This working paper present the main findings from previous studies on migration drivers and will serve as a baseline for the data collection on migration history and migration aspirations of young people in the Nordic countries.

Infrastructure has always been a fundamental driver of long-term economic growth, but in recent decades information and communication technology (ICT) has supported and accelerated the growth of the global economy in ways beyond the imagining of our ancestors. We examine the role of ICT infrastructure in facilitating labor markets' access and remittance flows for workers from the Kyrgyz Republic. Using a combination of traditional high frequency macroeconomic data and real time internet search information from Google Trends, we take a novel approach to explaining the inflow of remittances to a developing country. In the first attempt to model remittance behavior with GTI data in this context, we use a gravity model. We also attempt to account for both origin and destination labor market conditions, using Kyrgyz language search words to identify both push and pull factors affecting migrant decisions.

Food and You 2 is a biannual ‘Official Statistic’ survey commissioned by the Food Standards Agency (FSA). The survey measures self-reported consumers’ knowledge, attitudes and behaviours related to food safety and other food issues amongst adults in England, Wales, and Northern Ireland. Fieldwork for Food and You 2: Wave 3 was conducted between 28th April and 25th June 2021. A total of 6,271 adults from 4,338 households (an overall response rate of 31%) across England, Wales, and Northern Ireland completed the ‘push-to-web’ survey (see Annex A for more information about the methodology). This survey was conducted during the Covid-19 pandemic and so it records the reported attitudes and behaviours under unusual circumstances which have had a significant impact on how and where people buy and eat food, and on levels of household food insecurity. The modules presented in this report include ‘Food we can trust’, ‘Concerns about food’, ’Food security’, ‘Food shopping and labelling, ‘Online platforms’ and ‘Food-related behaviours and eating habits’

This short pedagogical movie illustrates an effect in nuclear physics called backbending which was first observed in the study of the rotational behavior of rapidly rotating rare-earth nuclei in Stockholm, Sweden in 1971. The video contains a mechanical analog utilizing rare-earth magnets and rotating gyroscopes on a turntable along with some historic spectra and papers associated with this landmark discovery together with its explanation in terms of the Coriolis induced uncoupling and rotational alignment of a specific pair of particles occupying high-j intruder orbitals. Thus backbending represents a crossing in energy of the groundstate, or vacuum, rotational band by another band which has two unpaired high-j nucleons (two quasi-particles) with their individual angular momenta aligned with the rotation axis of the rapidly rotating nucleus. Backbending was a major surprise which pushed the field of nuclear structure physics forward but which is now sufficiently well understood that it can be used as a precision spectroscopic tool providing useful insight for example, into nuclear pairing correlations and changes in the latter due to blocking effects and quasi-particle seniority, nuclear deformation, the excited configurations of particular rotational structures and the placement of proton and neutron intruder orbitals at the Fermi surface.
