Abstract:
Timber connection capacity, in case of beam-column joint connection provides significant impact on the wooden building structures. Strength and stiffness of timber connections using reinforcement technique of wooden building structures have not been studied intensively. This paper studies the use of nails and modified-washer to improve wood connection’s performance. The experimental tests were conducted in the laboratory by comparing the partial connection between test specimen timber without reinforcement (standard type) and the reinforcement (PRP type). The testing was conducted based on partial connection beam-column joint test using Universal Testing Machine’s with a modified holder. Wood studied includes Meranti (Shorea spp.) and Mersawa (Anisoptera spp.). PRP type connection was using nails and modified-washer strengthening, and standard type connection was using a classic washer. Parameters studied were strength and stiffness of the connection, reviewed both: proportional limit load and ultimate limit load conditions. Result obtained from this research indicates that the use of nails and modified-washer make a positive contribution to improving the performance of the beam- column timber joint connections, in terms of strength capacity (both of proportional limit and ultimate limit loads) and stiffness capacity (displacement ductility ratio). Meranti beam-column timber joint is more brittle than Mersawa beam column timber joint, it has an impact on the results. PRP-type of Mersawa timber connection produces a higher ductility than the standard type, while the PRP-type of Meranti timber connection produces a similar ductility to the standard type.

Abstract:
Variability is an important but neglected aspect of connectional neuroanatomy. The quantitative density of the ‘same’ corticocortical or thalamocortical connection may vary by over two orders of magnitude between different injections of the same tracer. At present, however, the frequency distribution of connection densities is unknown. Therefore, it is unclear what kind of sampling strategies or statistical methods are appropriate for quantitative studies of connectivity. Nor is it clear if the measured variability represents differences between subjects, or if it is simply a consequence of intra–individual differences resulting from experimental technique and the exact placement of tracers relative to local spatial and laminar variation in connectivity. W e used quantitative measurements of the density of a large number of corticocortical and thalamocortical connections from our own laboratories and from the literature. V ariability in the density of given corticocortical and thalamocortical connections is high, with the standard deviation of density proportional to the mean. The frequency distribution is close to exponential. Therefore, analysis methods relying on the normal distribution are not appropriate. W e provide an appendix that gives simple statistical guidance for samples drawn from exponentially distributed data. For a given corticocortical or thalamocortical connection density, between–individual standard deviation is 0.85 to 1.25 times the within–individual standard deviation. Therefore, much of the variability reported in conventional neuroanatomical studies (with one tracer deposited per animal) is due to within–individual factors. W e also find that strong, but not weak, corticocortical connections are substantially more variable than thalamocortical connections. We propose that the near exponential distribution of connection densities is a simple consequence of ‘patchy’ connectivity. W e anticipate that connection data will be well described by the negative binomial, a class of distribution that applies to events occurring in clumped or patchy substrates. Local patchiness may be a feature of all corticocortical connections and could explain why strong corticocortical connections are more variable than strong thalamocortical connections. This idea is supported by the columnar patterns of many corticocortical but few thalamocortical connections in the literature.

Abstract:
The behaviour of standard bolted steel connections submitted to monotonic loads, through the use of numerical models, is presented in the current paper. The bolted connections allow speed up constructive processes in an increasingly competitive and globalized world in which the costs are a decisive factor in the development of a project. The use of computational tools in the analysis of bolted connections becomes determinant, mainly for new solutions or solutions less explored in terms of design codes. Throughout the years, bolted connections have been suffering transformations resulting from research activities performed by many authors. Rivets have been replaced by bolts, the main achievement being the pre-stressed bolts. Methodologies based on finite element analyses were proposed for double shear bolted connection. The non-linear behaviour of these connections is investigated and their performances are compared. In the numerical modelling of the bolted connection, linear elastic and elastoplastic analyzes reveal that there are two slip levels associated with local non-linearities caused by the contact pairs, which vary with clamping stresses.

Abstract:
The behavior of a steel frame may be affected significantly by the moment versus rotational deformation (M–ϕ) behavior of its beam-to-column connections. Some of the effects of connection behavior are described and demonstrated. Because connection behavior is nonlinear and relatively difficult to model analytically, generally applicable analytical behavior models are not available. Nor, despite the availability of more than 300 experimentally measured connection M–ϕ data sets, are generally applicable empirically based behavior models available. Consequently, connection behavior continues to be accounted for only crudely in North American design specifications and in frame design. This paper describes a three-step strategy that would eventually permit the M–ϕ behavior of beam-to-column connections to be accounted for explicitly and routinely in steel design specifications and thus in frame design. The first step, to express connection M–ϕ behavior in a compact form suitable for incorporation into frame analysis software, has been demonstrated by curve fitting 274 experimental M–ϕ data sets to a specially developed function that requires only six parameters to describe connection behavior. The second step, to illustrate graphically the ranges of M–ϕ behavior exhibited by the common connection. types, and thereby to help designers to develop a "feel" for connection behavior, has been demonstrated by comparing the M–ϕ plots to the EUROCODE3 connection classification boundaries. The third step, to blend the standard connection geometries that have been developed in several countries into an international menu of standard connection geometries and, eventually, to generate and curve fit reliable experimental M–ϕ data for all of the standard connections, is summarized. Key words: beam-to-column connections, connection behavior, steel frames, structural analysis, steel design.

Abstract:
A novel method to improve the robustness of steel end plate connections is presented in this paper. Existing commonly adopted techniques alter the stiffness of the beam or the end plate to improve the connection’s robustness. In this study, the robustness is enhanced by improving the contribution of the bolts to the rotational capacity of connections; the higher the bolts’ elongation, the higher the rotational capacity that can be achieved. However, the brittleness of the bolt material, combined with its small length, results in negligible elongation. Alternatively, the load path between the end plate and the bolts can be interrupted with a ductile element to achieve the required elongation. This can be achieved by inserting a steel sleeve with a designated length, thickness, and wall curvature between the end plate and the washer. The proposed sleeve should be designed so that its ultimate capacity is less than the force in the bolt at failure; accordingly, the sleeve develops a severe bending deformation before the failure of any connection components. Using a validated finite element model, end plate connections with various parameters are numerically investigated to understand the performance of the sleeve device. The proposed system substantially enhances the rotational capacity of the connections, ranging between 1.37 and 2.46 times that of the standard connection. It is also concluded that the sleeved connections exhibit a consistent elastic response with the standard connections, indicating the proposed system is compatible with codified elastic design approaches without modification. Furthermore, for a specific connection, various ductile responses can be achieved without altering the connection capacity nor configuration.

Abstract:
The importance of beam-to-column connections in determining the load–deformation behaviour of steel building frames has been recognized for more than 70 years. Yet steel design specifications, including Canadian Standard Association standard CAN3-S16.1-M84, still mandate that connections be treated as either "pinned" or "rigid," and prescribe approximate design assumptions accordingly. Structural analysis procedures and tools exist that can account adequately for connection behaviour. What is not complete is the knowledge of the force–deformation behaviour of the various connection types.In this paper, what is known of the force–deformation behaviour of the commonly used connection types is described. The factors influencing that behaviour are outlined. Procedures for modelling connection behaviour and for incorporating it into structural analysis computer programs are described. The effects of connections on the behaviour of the overall structure are described and illustrated with examples. Finally, the areas where additional research is needed are discussed. Key words: connections, steel, structural analysis, columns, semirigid design.

Abstract:
Based on the field data, numerous failures of the downhole equipment of sucker rod pumping units occur, especially of the sucker rod strings. They are subject to corrosion, wear and alternating loads. The stress-strain state of the threaded connection elements is determined by the nature of the distribution of loads along the threads, which is uneven and depends on many factors. Despite this, the development of new designs of sucker rod connections and measures to improve the efficiency of operation and their research is an urgent task. In addition to the threaded connections of the sucker rods, there were a number of threadless designs that were not used in the fields, but they passed certain tests. The article presents these connection designs and discusses their advantages and disadvantages in comparison with standard threaded connections. Simulation modeling of a standard connection of sucker rods made it possible to investigate its stress-strain state and identify hazardous areas (stress concentrators). The stress-strain state of the threaded connection of the sucker rods has been investigated, the design of this connection has been improved and it has been established that, in comparison with the standard threaded connection of the sucker rods, the investigated has certain advantages. It was found that with an increase in the number of protrusions and depressions in a threaded joint, stresses decrease, which are concentrated in dangerous sections and along the contact planes. Convex contact planes also reduce stress, especially at the joint surface. Research has shown that the stresses generated in a threadless sucker rod joint are less than the stresses generated in a standard sucker rod and sleeve joint. Although the difference between these stresses is insignificant, attention should be paid to changing the geometric parameters of the threadless connection of the sucker rods, thereby reducing the maximum stresses.

Abstract:
A practical method for incorporating realistic flexible connections in plane frame analysis, including the effect of connection sizes and shear deflection, is presented. The general algorithm can be easily implemented in a standard plane frame analysis program and, once implemented, it can be an ideal tool for production work in the steel industry. Connection stiffness is programmed directly into the analysis using the moment–rotation equations developed by Frye and Morris or may be entered separately as data. Practical application of this method of analysis is demonstrated by modifying a standard plane frame analysis program to include the effect of flexible connections. Solutions obtained using this modified program, CPlane, were verified against the findings of Moncarz and Gerstle. A simple plane frame structure was analyzed under various lateral load intensities for different connection assumptions. It was found that the inclusion of connection behavior significantly altered the internal force distribution and design of the structure. Key words: connections, matrix frame analysis, moment–rotation relations.

Abstract:
The scope of the paper is to propose a method for determining the size of shear caps in a slab–column-connections-reinforced concrete structure. Usually, shear heads are used to enhance slab–column connection, especially when the transverse reinforcement does not give the required punching shear load capacity. The dimensions of the shear head should provide the punching shear resistance of the connection inside and outside the enhanced region. The process of selecting the size of the shear head is iterative. The parametric analysis of the ACI 318 code and EC2 standard has the objective of indicating which control perimeter (inside or outside the shear head) has a decisive impact on the punching shear capacity of the connection. Based on the analysis, the authors propose methods for selecting the dimensions of the shear head with practical application examples. The paper is intended to provide scientists, civil engineers, and designers with guidelines to design the process of the slab–column connections with the shear caps.

Abstract:
Актуальність теми. Одним з шляхів розвитку електричних мереж на території України є підключення нових побутових та промислових споживачів, а саме реконструкція існуючих ліній для дотримання рівня якості електроенергії. Основними проблемами є: - непрозорість надання послуг з приєднання електричних установок до електричних мереж; (Основною проблемою приєднання є те що, вам ніколи ніхто точно не скаже зразу – скільки коштуватиме приєднання до електричної мережі з певної точки на карті і за який час це буде виконано. Це явище створює можливості для «торгів» з клієнтами для «вичавлювання» з них максимальної економічної вигоди». Саме через це багато іноземних інвесторів переносить своє виробництво до інших країн). - непрозора процедура визначення плати за приєднання до електричних мереж; (Плата за приєднання має бути недискримінаційною та прозорою, а також публікуватися у відкритому доступі. – з такими умовами кожен зможе підрахувати ціну з точністью до 90-95%, але залишається питання прозорості. Зараз замовнику можуть поставити вимоги які рівні, або й перевищують ціну звичайного приєднання) - невідповідність законодавства України законодавству ЄС; (Після підписання Президентом України закону про «Про ринок електричної енергії» стартував дворічний перехід, під час якого всю архітектуру ринку перебудують у відповідність до правил, які працюють в ЄС. В галузі повинна з’явитися конкуренція і зникнути перехресне субсидіювання) Та ще багато інших проблем, які будуть розглянуті в цій роботі, тож я вважаю що тема досить актуальна. За результатами аналізу технічного стану енергетичної галузі України встановлюємо її незадовільний технічний стан та організацію експлуатації, що впливає на подальший розвиток економіки країни та життєвий рівень населення. Відповідно до міжнародних зобов’язань Україна має забезпечити розвиток бізнесу (зокрема підняття свого рейтингу Doing Business), адже на сьогодні рівень України ще не задовольняє інтереси суспільства. Для забезпечення належного рівня України принциповим питанням є спрощення процедури та пошук оптимальності приєднання до електричних мереж. Мета та завдання досліджень. Полягає у огляді та вирішення питань стосовно підвищення ефективності функціонування мереж електропередавальних організацій в частині приєднання споживачів до електричних мереж шляхом організаційно-управлінських, технікоекономічних, нормативно-правових, екологічних та технологічних питань. Об’єкт дослідження – процеси організації приєднання споживачів до електричних мереж електропередавальної організації. Предмет дослідження – методи підвищення ефективності організації приєднання. Методи дослідження. Методологічну основу проведеного наукового дослідження склали такі методи: нечітка логіка (теорія масового обслуговування), кластерний аналіз даних трансформаторних підстанцій, математично-фізичні розрахунки. Наукова та практична цінність роботи полягає у проведенні дослідження організаційно-управлінських, техніко-економічних, нормативно-правових, екологічних та технологічних питань, формуванні пропозиції по підвищенню ефективності діяльності електропередавальної організації щодо приєднання споживачів до електричних мереж, а також у розробці пропозицій запровадження геоінформаційної системи управління розвитком та експлуатацією об’єктів енергетики в Україні.
Actuality of theme. One of the ways to develop electricity networks in Ukraine is to connect new household and industrial consumers, namely the reconstruction of existing lines to meet the level of electricity quality. The main problems are: - non-transparency of electricity connection services installations to electric networks; (The main problem with joining is that, you never have exactly anyone will tell at once - how much will cost connection to an electric network with a certain point on the map and how long it will take. This phenomenon creates opportunities to "bid" with customers to "squeeze" out of them maximum economic benefit ". That is why many foreigners investors transfers their production to other countries). - non-transparent procedure for determining the fee for connection to the electricity grid; (The accession fee should be non - discriminatory and transparent, and also be published in the public domain. - with such conditions everyone will be able to calculate the price with an accuracy of 90-95%, but remains issues of transparency. Now the customer can set requirements which equal to, or exceed the cost of a conventional connection) - inconsistency of Ukrainian legislation with EU legislation; (After the President of Ukraine signed the law on the electricity market, a two-year transition began, during which the entire market architecture will be rebuilt in accordance with the rules in force in the EU. Competition should appear in the industry and cross-subsidization should disappear) Yes, there are many other issues that will be considered in this paper, so I think that the topic is quite relevant. Based on the results of the analysis of the technical condition of the energy industry of Ukraine, we establish its unsatisfactory technical condition and organization exploitation, which affects the further development of the country's economy and living standards of the population. In accordance with Ukraine's international obligations should ensure business development (including raising its Doing rating) Business), because today the level of Ukraine does not satisfy the interests society. To ensure the proper level of Ukraine in principle the question is to simplify the procedure and find the optimal connection to electrical networks. The purpose and objectives of research. It consists in reviewing and resolving issues related to improving the efficiency of networks of electricity transmission organizations in terms of connecting consumers to electricity networks through organizational and managerial, technical and economic, regulatory, environmental and technological issues. The object of research - the processes of organization of connection of consumers to the electrical networks of the power transmission organization. The subject of research - methods to increase the efficiency of the organization of accession. Research methods. The methodological basis of the conducted research was the following methods: fuzzy logic (queuing theory), cluster analysis of transformer substation data, mathematical and physical calculations. The scientific and practical value of the work lies in the study of organizational and managerial, technical and economic, regulatory, environmental and technological issues, the formation of proposals to improve the efficiency of the transmission organization to connect consumers to electricity networks, as well as the development of proposals for geographic information management system development and operation of energy facilities in Ukraine.

Abstract:
A number of companies have developed a variety of network approaches to the transfer of audio and MIDI data. By doing this, they have addressed the configuration complications that were present when using direct patching for analogue audio, digital audio, word clock, and control connections. Along with their approaches, controlling software, usually running on a PC, is used to set up and manage audio routings from the outputs to the inputs of devices. However one of the advantages of direct patching is the conceptual simplicity it provides for a user in connecting plugs of devices, the ability to connect from the host plug of one device to the host plug of another. The connection management or routing applications of the current audio networks do not allow for such a capability, and instead employ what is referred to as a two-step approach to connection management. This two-step approach requires that devices be first configured at the transport layer of the network for input and output routings, after which the transmit and receive plugs of devices are manually configured to transmit or receive data. From a user’s point of view, it is desirable for the connection management or audio routing applications of the current audio networks to be able to establish routings directly between the host plugs of devices, and not the audio channels exposed by a network’s transport, as is currently the case. The main goal of this work has been to retain the conceptual simplicity of point-to-point connection management within digital audio networks, while gaining all the benefits that digital audio networking can offer.

Abstract:
Les dernières décennies ont connu l'apogée des transmissions hertziennes, et celles à venir connaîtront incontestablement le développement et le déploiement intense de systèmes de communications sans-fil. Dès à présent, il est possible de communiquer par onde sur petite et très petite distance (LAN et PAN). Les populations se sont familiariséesavec les interfaces bluetooth (IEEE802.15) présentes dans la majorité des objetscommuniquant (ordinateur portable, téléphone, PDA, etc...). Les foyers s'équipentmaintenant facilement et à bas prix d'interfaceWi-Fi (IEEE802.11), afin de profiter d'uneutilisation nomade de leur accès internet. Ainsi, la forte croissance dumarché des offresinternet combinée avec celle du marché des téléphones mobiles ont habitués un large spectre d'utilisateurs à communiquer sans fil. Ce contexte sociologique et financier encourage donc l'arrivée de solutions nouvelles répondant à des besoins latents. Parmi ceux-là, le marché met en évidence le manque de système de communication sur moyenne distance (MAN). Les réseaux ad-hoc peuvent répondre à ce genre de besoin. Mais àce jour, les performances sont trop faibles pour les besoins des utilisateurs et elles dépendenttrop fortement de la densité desmachines nomades. Aussi, le consortiumIEEEcherche au travers de sa norme IEEE802.16 à fournir un système complet de communicationsans-fil sur moyenne distance (MAN). Appelé aussiWiMAX, ce système se basesur une architecture composée d'une station de base (BS) et de nombreux mobiles utilisateurs(SS). Le standard IEEE802.16 définit les caractéristiques de la couche physiqueet de la couche MAC. Il décrit l'ensemble des interactions et événements pouvant avoirlieu entre la station de base et les stations mobiles. Enfin, le standard fournit différents paramètres et variables servant aux mécanismes de communication. Comme tout nouveau standard émergeant, la norme IEEE802.16 ne profite pas d'un état de l'art aussi développé que celui du IEEE802.11 par exemple. Aussi, de nombreuses études et idées sont à développer.En premier lieu, nous effectuons un large rappel de la norme WiMAX et en particulier le IEEE802.16e. Associé à cela, nous dressons un état de l'art des travaux traitant des aspects et perspectives liés au sujet de notre étude.Par la suite, nous proposons un modèle novateur de performance des communicationsIEEE802.16e. Au travers de ce modèle, nous développons une étude générale et exhaustive des principaux paramètres de communication. L'étude explicite l'impact deces paramètres ainsi que l'influence de leur évolutions possibles. De cela, nous critiquonsla pertinence de chacun d'eux en proposant des alternatives de configurations.5En sus, nous proposons un mécanisme novateur favorisant le respect de qualité de service(QoS) sur couche AC.Nous développons un principe original d'établissement de connexion favorisant l'accès aux communications sensibles aux délais de transmission.Dans une dernière partie, nous déterminons la capacité d'un système IEEE802.16 à gérer les arrivées et départs des utilisateurs. Tout en y associant une étude de performance d'un nouvel algorithme de contrôle d'admission. Cet algorithme d'admission vise à remplir des objectifs multiples : empêcher les famines de ressources sur les trafics les moins prioritaires, favoriser l'admission des utilisateurs en maintenant une gestion optimale de la ressource radio. Notre étude aboutit à une modélisation et une critique des variations de paramètre associés à ce nouvel algorithme. Nous y intégrons par la suite le principe de mobilité où les utilisateurs ont la capacité de se mouvoir au sein d'une cellule. Cette intégration se fait en y associant des mécanismes originaux afin d'assurer la pérennité du service aux utilisateurs mobiles.

Abstract:
This thesis is purposed to understand and mathematically formulate a model for testing the functional value of self-expression in the workplace. Starting from “pure self-expression”, this paper develops “functional self-expression” in given contexts. This development is through the lens of an idealized workplace context whose intrinsic value is profit-maximizing. This perspective is dominating and fills the entire surface to which the self can express too. The logical foundations of this paper begin anecdotal and transcend to holistic visualizations and a concluding model. In the end, we discover that the self-expression within “friendship” poses a threat to the idealized dominating context of the workplace.

Abstract:
One of the primary targets of current and especially future cosmological observations are light thermal relics of the hot big bang. Within the Standard Model of particle physics, an important thermal relic are cosmic neutrinos, while many interesting extensions of the Standard Model predict new light particles which are even more weakly coupled to ordinary matter and therefore hard to detect in terrestrial experiments. On the other hand, these elusive particles may be produced efficiently in the early universe and their gravitational influence could be detectable in cosmological observables. In this thesis, we describe how measurements of the cosmic microwave background (CMB) and the large-scale structure (LSS) of the universe can shed new light on the properties of neutrinos and on the possible existence of other light relics. These cosmological observations are remarkably sensitive to the amount of radiation in the early universe, partly because free-streaming species such as neutrinos imprint a small phase shift in the baryon acoustic oscillations (BAO) which we study in detail in the CMB and LSS power spectra. Building on this analytic understanding, we provide further evidence for the cosmic neutrino background by independently confirming its free-streaming nature in different, currently available datasets. In particular, we propose and establish a new analysis of the BAO spectrum beyond its use as a standard ruler, resulting in the first measurement of this imprint of neutrinos in the clustering of galaxies. Future cosmological surveys, such as the next generation of CMB experiments (CMB-S4), have the potential to measure the energy density of relativistic species at the sub-percent level and will therefore be capable of probing physics beyond the Standard Model. We demonstrate how this improvement in sensitivity can indeed be achieved and present an observational target which would allow the detection of any extra light particle that has ever been in thermal equilibrium. Interestingly, even the absence of a detection would result in new insights by providing constraints on the couplings to the Standard Model. As an example, we show that existing bounds on additional scalar particles, such as axions, may be surpassed by orders of magnitude.

Abstract:
This study examines the messages and accuracy of the messages sent to students from the Arizona Instrument to Measure Standards (AIMS) math test regarding academic preparedness for postsecondary education. Previous studies investigating messages sent to students, derived from information such as educational standards, grades, course taking policies, test material, and college admissions requirements, focused on content alignment of secondary and postsecondary content standards. However, a dearth of research exists on messages from high school performance, as measured by exit exams and college performance measured by grades, major selection, or graduation. This study addresses the need to understand and interpret messages students receive based on academic performance. Specifically, this study aims to answer three questions. First, what is the relationship between AIMS math scores and college math performance defined by the University of Arizona math requirement and college graduation? Second, to what degree do AIMS math scores predict college math performance? Third, what is the average AIMS math score and performance level for students who choose certain majors? To answer the research questions posed in this study, various statistical analyses were employed. To answer the first question, a one-way ANOVA and logistic regression analyses were used. A linear regression analysis served to analyze the second and third questions. Results indicate that the messages sent to students regarding college readiness are, in fact, well aligned and clear and consistent. Also, there is evidence that the messages vary by gender and ethnicity.

Abstract:
AbstractTraditional analytical methods are approximate and need to be validated when it comes to predict the tensional behavior of thread coupling. Numerical finite element simulations help engineers come up with the optimum design, although the latter depends on the constraints and load conditions of the thread couplings which are often variable during the system functioning. The present work illustrates a new method based on Radial Basis Functions Mesh Morphing formulation to optimize the stress concentration in thread couplings which is subject to variable loads and constraints. In particular, thread root and fillet under-head drawings for metric ISO thread, which are the most commonly used thread connection, are optimized with Radial Basis Functions Mesh Morphing. In metric ISO threaded connection, the root shape and the fillet under the head are circular, and from shape optimization for minimum stress concentration it is well known that the circular shape becomes seldom optimal. The study is carried out to enhance the stress concentration factor with a simple geometric parameterization using two design variables. Radial Basis Functions Mesh Morphing formulation, performed with a simple geometric parameterization, has allowed to obtain a stress reduction of up to 12%; some similarities are found in the optimized designs leading to the proposal of a new standard. The reductions in the stress are achieved by rather simple changes made to the cutting tool.

Abstract:
Abstract The ability to reconfigure automation equipment will reduce the manufacturing costs of obsolesence, training and maintenance while allowing for a faster response to changes in the product line. A modular philosophy will give the user these advantages, but only if based on a common connection standard. A mechanical connection was selected for the UT Modular Robotics Testbed and used in the designs of four robot joint modules and nine robot link modules. The standard was also used for assecories, such as the testand, loading fixtures and endeffectors. Three years of experiments with this connection standard are reviewed, and used as the basis for new connection designs. Experiments using multiple modules assembled as dextrous robots, as well as experiments focusing on the connection itself, will be described. Goals for future connection standards include designs with upward compatibility, combinations of both mechanical and electrical fittings, and robot triendly constraints that allow for automated or remote assembly of modular robots.

Full text
Abstract:
Abstract Understanding the structural limits of subsea connectors used in offshore environments is critical to ensure safe operations. The latest industry standards establish the requirement for physical testing to validate analysis methodologies for connector designs. In this paper, an analysis methodology, compliant with the latest API 17G standard, is presented for calculating structural capacities of non-preloaded connectors. The methodology has been developed for complex combined loading scenarios and validated using full-scale physical testing for different connector families. Detailed 3-D, non-linear, finite element models were developed for three different non-preloaded connections, which consisted of threaded and load shoulder connectors. A comprehensive set of combined tension and bending moment structural capacities at normal, extreme and survival conditions were calculated for each connection. The calculated capacities were validated for each connection by performing a test sequence using full-scale structural testing. A final tension or bending to failure test was also completed for each test connection to validate the physical failure mode, exceeding the latest API 17G requirements. For all connections tested, capacities calculated using the methodology were validated from the successful completion of the test sequences. The physical failure modes of the test connections also matched the predicted failure modes from the FEA, and the tensile or bending moment loading at physical collapse exceeded that predicted by the global collapse of the FEA model. Using the validated approach described in this paper significantly reduces the requirement of physical testing for connector families, establishing confidence in the structural limits that are critical for safe operations.

In contrast to the case of parallel connection of multiple oscillators, the results are presented through the matrix formulation of charging on capacitance. Besides, they are validated numerically by standard circuit simulations.

Abstract:
The new analytical calculation method for gasketed circular flange connections NF EN1591-1 [3], has been issued in Europe in 2001. It is an alternative to the existing TAYLOR FORGE gasketed flange connections calculation rules. This standard, based on tightness criteria, gives a more detailed analytical modelling of the behaviour of the connection. However, the “full face” gaskets, located on each side of the bolt circle, are out of the scope of NF EN1591-1 [3], whereas a method partly based on the TAYLOR FORGE rules is proposed in the NF EN 13445-3 [6] and CODAP® [10]. A proposal for the calculation of “full face” gasketed joints, based on [3] is presented here.

Full text
Abstract:
When establishing oil wells, pipe sections are connected by means of threaded couplings. In an effort to minimize the possibility of failure by jumpout, standard buttress connections were introduced. Part of their strength is directly acquired as a result of radial interference during make-up. This paper discusses the results of a numerical study evaluating the effect of make-up on the performance of a standard 4.5 inch API buttress connection when axial tensile force is applied. In order to characterize the structural performance, the load distribution along the coupling length is evaluated, combined with a parameter defining thread separation. The latter is indicative for jumpout and the tendency of creating a leak path throughout the thread helix. From the results it is clear that relative axial displacement within the coupling occurs, even when made up, because of an initial clearance among the load and stab flanks. This clearance may cause a connection to leak through the thread helix when available thread compound cannot heal this leak path. Despite undesirable effects on the sealability and rigidness of this joint, such a clearance is required to decrease frictional forces during make-up while maintaining the desired radial interference.

Abstract:
Identifying and evaluating climate expenditures in the public sector, known as budget tagging, has generated increasing attention from multiple stakeholders, not only to assess the governments climate change policy, but also to monitor fiscal risks associated with increasing and unpredictable climate change impacts. This paper explores the issues raised by climate change budget tagging in the context of a broader discussion on the connections with fiscal and environmental statistical classification systems. It argues that, for climate change budget tagging efforts to be successful, the definitions and classifications of climate change expenditures must be consistent with statistical standards currently in use, such as the Government Finance Statistics Framework and the System of National Accounts.

Inter-American Development Bank, December 2021. http://dx.doi.org/10.18235/0003842.

Full text
Abstract:
The Caribbean islands are among the 25 most-vulnerable nations in terms of disasters per-capita or land area, and climate change is only expected to intensify these vulnerabilities. The loss caused by climate events drags the ability of the Caribbean countries to invest in infrastructure and social programs, contributing to slower productivity growth, poorer health outcomes, and lower standards of living. Within this context, building resiliency should become a priority for the Caribbean countries. The series “Building a more resilient and low-carbon Caribbean”, focuses on improving the resiliency, sustainability and decarbonization of the construction industry in the Caribbean. The results show that increasing building resiliency is economically viable for the high-risk islands of the Caribbean, generating long term savings and increasing the infrastructure preparedness to the impacts of CC. Report 1 - Climate Resiliency and Building Materials in the Caribbean, presents a quantification of the economic losses caused by climate impact events in the Caribbean Region and correlate these figures with the most common construction materials, typically used in each of the countries building typologies. The losses caused by hurricanes concentrate mostly in the residential infrastructure and are mainly caused by weaknesses in roofs and their connection to the walls. The analysis suggests that improving the resiliency of outer walls and roofs in the Caribbean could significantly reduce the regions vulnerability to hurricanes and other climate impacts.

Abstract:
The article is devoted to a comparative analysis of popular online dictionaries and an overview of the main tools of these resources to study a language. The use of dictionaries in learning a foreign language is an important step to understanding the language. The effectiveness of this process increases with the use of online dictionaries, which have a lot of tools for improving the educational process. Based on the Alexa Internet resource it was found the most popular online dictionaries: Cambridge Dictionary, Wordreference, Merriam–Webster, Wiktionary, TheFreeDictionary, Dictionary.com, Glosbe, Collins Dictionary, Longman Dictionary, Oxford Dictionary. As a result of the deep analysis of these online dictionaries, we found out they have the next standard functions like the word explanations, transcription, audio pronounce, semantic connections, and examples of use. In propose dictionaries, we also found out the additional tools of learning foreign languages (mostly English) that can be effective. In general, we described sixteen functions of the online platforms for learning that can be useful in learning a foreign language. We have compiled a comparison table based on the next functions: machine translation, multilingualism, a video of pronunciation, an image of a word, discussion, collaborative edit, the rank of words, hints, learning tools, thesaurus, paid services, sharing content, hyperlinks in a definition, registration, lists of words, mobile version, etc. Based on the additional tools of online dictionaries we created a diagram that shows the functionality of analyzed platforms.

Abstract:
As scientists, we aim to generate new knowledge and insights about the world around us. We often measure the impacts of our research by how many times our colleagues reference our work, an indicator that our research has contributed something new and important to our field of study. But how does our research contribute to solving the complex societal and environmental challenges facing our communities and our planet? The goal of this guidebook is to illuminate the path toward greater societal impact, with a particular focus on this work within the natural and physical sciences. We were inspired to create this guidebook after spending a collective 20+ years working in programs dedicated to moving climate science into action. We have seen firsthand how challenging and rewarding the work is. We’ve also seen that this applied, engaged work often goes unrecognized and unrewarded in academia. Projects and programs struggle with the expectation of connecting science with decision making because the skills necessary for this work aren’t taught as part of standard academic training. While this guidebook cannot close all of the gaps between climate science and decision making, we hope it provides our community of impact-driven climate scientists with new perspectives and tools. The guidebook offers tested and proven approaches for planning projects that optimize engagement with societal partners, for identifying new ways of impacting the world beyond academia, and for developing the skills to assess and communicate these impacts to multiple audiences including the general public, colleagues, and elected leaders.

CAPACITY EVALUATION OF EIGHT BOLT EXTENDED ENDPLATE MOMENT CONNECTIONS SUBJECTED TO COLUMN REMOVAL SCENARIO. The Hong Kong Institute of Steel Construction, September 2021. http://dx.doi.org/10.18057/ijasc.2021.17.3.6.

Full text
Abstract:
The extended stiffened endplate (8ES) connection is broadly used in the seismic load-resisting parts of steel structures. This connection is prequalified based on the AISC 358 standard, especially for seismic regions. To study this connection’s behaviors, in the event of accidental loss of a column, the finite element model results were verified against the available experimental data. A parametric study using the finite element method was then carried out to investigate these numerical models’ maximum capacity and effective parameters' effect on their maximum capacity in a column loss scenario. This parametric analysis demonstrated that these connections fail at the large displacement due to the catenary action mode at the rib stiffener's vicinity. The carrying capacity, PEEQ, Von-Mises stress, middle column force-displacement, critical bolt axial load, and the beam axial load curves were discussed. Finally, using the Least Square Method (LSM), a formula is presented to determine the displacement at the maximum capacity of these connections. This formula can be used in this study's presented method to determine the maximum load capacity of the 8ES connections in a column loss scenario.
