An experimental program under cyclic load is performed on two half-scale interior moment end-plate connections to concrete filled tubular (CFT) columns. Flat and curved stiffened extended end-plates were welded to the steel beams in the shop, and bolted on the site to the square and circular CFT column tubes respectively, using steel rods passing through the column. The experimental results demonstrated that both circular and rectangular end-plate connections showed similar performance in a ductile manner and the stiffener elements were effective to form the plastic hinges away from the welding zone, also the proposed curved end-plate connection with rods passing through the column in “X” shape was effective. The test specimens showed a plastic rotations capacity of 0.054 radian.

Neural algorithms require massive computation and very high communication bandwidth and are naturally expressed at a level of granularity finer than parallel systems can exploit efficiently. Mapping Neural Networks onto parallel computers has traditionally implied a form of clustering neurons and weights to increase the granularity. SIMD simulations may exceed a million connections per second using thousands of processors, but are often tailored to particular networks and learning algorithms. MIMD simulations required an even larger granularity to run efficiently and often trade flexibility for speed. An alternative technique based on pipelining fewer but larger messages through parallel. “broadcast/accumulate trees” is explored. “Lazy” allocation of messages reduces communication and memory requirements, curbing excess parallelism at run time. The mapping is flexible to changes in network architecture and learning algorithm and is suited for a variety of computer configurations. The method pushes the limits of parallelizing backpropagation and feed-forward type algorithms. Results exceed a million connections per second already on 30 processors and are up to ten times superior to previous results on similar hardware. The implementation techniques can also be applied in conjunction with others, including systolic and VLSI.

Recent studies show that a through beam connections composed of concrete filled square steel tubular column and steel beam have been identified as an ideal rigid connection. In this paper a 3-D nonlinear finite element models were conducted for CFSST column and steel beam connection under monotonic load using ABAQUS software. Each model includes a CFSST column and single steel beam passing through the column. The main scopes are to identify the modes of beam failure and joint shear failure. In addition the effect of an extra shear plate welded to beam web inside the column was investigated. This result can be used for designing of through beam connection.

Enhancing message propagation is critical for solving the problem of node classification in sparse graph with few labels. The recently popularized Graph Convolutional Network (GCN) lacks the ability to propagate messages effectively to distant nodes because of over-smoothing. Besides, the GCN with numerous trainable parameters suffers from overfitting when the labeled nodes are scarce. This article addresses the problem via building GCN on Enhanced Message-Passing Graph (EMPG). The key idea is that node classification can benefit from various variants of the input graph that can propagate messages more efficiently, based on the assumption that the structure of each variant is reasonable when more unlabeled nodes are labeled properly. Specifically, the proposed method first maps the nodes to a latent space through graph embedding that captures the structural information of the input graph. Considering the node attributes together, the proposed method constructs the EMPG by adding connections between the nodes in close proximity in the latent space. With the help of the added connections, the EMPG allows a node to propagate its message to the right nodes at long distances, so that the GCN built on the EMPG need not stack multiple layers. As a result, over-smoothing is avoided. However, dense connections may cause message propagation saturation and lead to overfitting. Seeing the EMPG as an accumulation of some potential variants of the original graph, the proposed method utilizes dropout to extract a group of variants from the EMPG and then builds multichannel GCNs on them. The multichannel features learned from different dropout EMPGs are aggregated to compute the final prediction jointly. The proposed method is flexible, as a brod range of GCNs can be incorporated easily. Additionally, it is efficient and robust. Experimental results demonstrate that the proposed method yields improvements in node classification.

Texto completoResumen
This article explores how mundane objects are passed on through kinship networks and how these practices become part of the ‘doing’ of family and kinship. Using Mason’s concept of affinities, I illuminate four strands of material affinities, each of which illustrates how passed on objects can reproduce, imagine and memorialise kin connections both biological and social, and in and through time. Crucially, I argue that it is everyday objects in use which reveal how materiality and kinship are woven together. By starting from the object rather than the subject material affinities are brought to life, illustrating how materials are inscribed with kinship both physically and imaginatively, but in turn inscribe kinship practices, operating as central characters in family narratives. The article stems from research exploring everyday contemporary thrift and involved one-to-one interviews and a Mass Observation Directive on the subject of ‘Being thrifty’.

Texto completoResumen
The validation and accuracy of internet protocol version 6 (IPv6) performance using jumbo frames is still not perfect, due to peer-to-peer connections testing within the same operating system and between operating systems. Therefore, inaccurate data test results. To mitigated, testing with a wider platform is recommended, a medium-scale network connection is proposed such as metropolitan area networks. In this works, a connection between computer devices connected by three proxy routers are made, with different IPv6 segments on each port. Then each computer device sends traffic data to each other using a traffic-generator application. The first test through three routers without tunnel connection is carried out as the first scenario to compare performance with tunnel-based testing. Three parameters have been used in this test, such as maximum transfer unit (MTU) 1500 bytes, MTU 400 bytes and MTU 9000 bytes. The results of the tests conducted show that the use of jumbo frames using a proxy is less effective, even though it produces a larger throughput when using the MTU 4000, but there is fragmentation in the packet passing through the proxy because the packet passing through the proxy is split into 1500 byte sizes.

Texto completoResumen
This paper presents a new-type of fabricated beam-column connections with end plates. The joint details are as follows: the concrete beams are connected to column by end plates and six high strength long bolts passing through the core area. In addition, in order to increase the stiffness and shear strength, stirrups are replaced by the steel plate hoop in the core zone. To examine the fail behavior of the fabricated beam-column connection specimens, a quasi-static test is conducted for nine full-scale models to obtain the hysteresis curves, skeleton curves, ductility, energy dissipation capacity, and other seismic indicators. The experimental results show that all specimens failed in bending in a malleable way with a beam plastic hinge and the hysteresis curves are excellently plump for the end plate connections. From the seismic indexes, the fabricated connection specimens exhibit better seismic performance, which can provide reference for the application of prefabricated frame structure in the earthquake area.

Abstract Determining the connectivity of team members in sport provides important information on team functioning. In soccer, teams that are highly connected via passing have been shown to be more successful compared to teams less connected via passing. In addition to passing connectivity, players are connected with each other via intra-team communication (ITC) through verbal instruction, and nonverbal cues. Despite ITC being a known component of effective teamwork to enhance strategy, efficiency, motivation and concentration, ITC of individual playing positions has not previously been measured during soccer games, nor has it been associated with passing connections in a performance context. In this study, the received ITC that was perceived to be beneficial to performance during 22 competitive professional soccer matches was measured, in conjunction with the passing connections between team members. In total, 526 ITC ratings were collected and analysed, and a total of 7,693 passes were analysed. From the ITC and passing measures, a player connectivity index (PCI) representing the coupling of ITC and passing, was developed to determine the overall connectivity of the individual playing positions. Social network analysis (SNA) centrality metrics were used to determine the connectivity of the playing positions. There were significant (p < .05) main effects between playing positions for beneficial ITC, passing, and the PCI for centrality metrics, indicating that different playing positions interact with other team members differently. Pairwise comparisons indicated significant differences between individual playing positions for ITC, passing and the PCI. The two central defenders and the two central defensive midfielders had the highest mean values for ITC, passing, and the PCI compared to the other playing positions. The current findings suggest that central defenders and central defensive midfielders are positioned tactically to be highly involved in the build-up of passing moves, and to deliver beneficial task related information to team members. These findings have implications for performance analysis, coaches, and for talent identification.

Texto completoResumen
In steel moment-resisting frames, tubular columns have many structural and architectural advantages over open-section columns. Circular Hollow Sections (CHS) are in fact particularly recommended for structural elements subjected to compression and bending forces in all directions, thanks to their higher radius of gyration and the axial-symmetric distribution of their mechanical properties. Therefore, the use of CHS profiles for the realization of columns can lead to a reduction of the total costs and furthermore to simplifications in the realization process of steel-concrete composite structures. However, the difficulties in realizing tubular column joints adopting open I-section beams, the most commonly used all around the world, severely reduce the use of CHS columns.
Nowadays, I-beam-to-CHS-column steel and composite joints are commonly realized in two main ways: i) the connection is made by directly welding the beams or the beam stub to the wall of the steel tube; ii) supplemental plates are used to connect the beams to the circular column. The direct connection is the most convenient solution in terms of rapidity and easiness of fabrication but the performance of the joint is strongly limited by significant local distortions of the tube wall near the girder flanges. Therefore, the joint performance results very far from the ideal mechanical behavior of a rigid full-strength beam-to-column connection.
The local buckle of the tube wall, which can lead to brittle failures, often suggests the use of supplemental plates for the realization of the tubular column joints. Additional elements can indeed assure a more effective transfer of the stresses from the beam flanges to the column wall or from the flanges of one beam directly to the beam placed on the opposite side. In general, two types of additional elements are currently used for I-beam-to-CHS-column moment joints: interior diaphragm joints, which imply the discontinuity of the column, and exterior diaphragm joints, which guaranty the total continuity of the column. Although internal diaphragms are very effective in distributing the internal forces and improving the collaboration between the steel elements and the concrete core in the case of composite columns, their use implies a discontinuity in the column and requires extensive welding to reconnect the column pieces. On the contrary, exterior diaphragms guarantee the steel tube continuity through the connection; nevertheless, several welding should be performed also in this case. Moreover, in the case of filled column, the composite behavior is not improved by the presence of steel elements, and the presence of big external stiffeners spoils down the aesthetic of the whole building.
To overcome the main issues inherent the direct connections and the use of diaphragms, innovative solutions with continuous passing-through elements inside the column were studied, highlighting several advantages from a mechanical point of view. Indeed, the continuous elements can pass by slots of limited size made on the column wall, without requiring the complete discontinuity of the column itself and the joint requires less cutting and welding operations, resulting in lower overall cost and better mechanical behavior. The use of passing-through elements can lead to obtain the same mechanical benefits highlighted by internal diaphragms joints, without requiring the complete discontinuity of the column wall in the joint. However, despite all these advantages, many problems arise from the fabrication and constructional points of view, limiting the effective performance of the joints. Indeed, the difficulties in implementing high precision cutting processes spoiled the development of this construction technique, favoring more practice solutions.
One of these difficulties lies in the production tolerances that affect the effective geometry of the beams. These tolerances shall be considered in the definition of the dimensions of the slots in which the beams need to pass through: dimensions of the slot very close to the nominal ones of the beam can lead to difficulties in the assembly process, whereas big gaps can result in ineffective welding. One of the solutions to overcome the difficulties in the fabrication and constructional processes of this joint typology lies in the application of the modern Laser Cutting Technology (LCT) to steel and composite structures. Laser cutting machines, commonly used in the industrial field, allow performing high precision and completely automated cutting processes on steel tubes and open sections profiles with the typical structural dimensions. To limit the influence of the beam dimensions tolerances, the laser cutting machines have the intrinsic advantage of directly providing measuring instruments that can be used to measure the elements to be passed. Therefore, the whole fabrication process can start with the simultaneous cutting and measuring process of the I-beams and plates. Subsequently, slots can be realized on the tube-wall considering the previously taken and recorded measurements and applying a defined strict tolerance margin. In this way the correct passage of the beam portions or plates through the column is guaranteed without requiring excessive gaps, and the welding processes is performed in the best conditions. Furthermore, thanks to the possibility of cutting with different inclinations with the tube-face, the penetration welding may be realized without performing any additional preparation processes on the worked-pieces. The LCT is also a very competitive solution in terms of time of fabrication and cost, thanks to the high automatization of the process reached by the modern technologies.
However, even though the LCT provides the perspective of realizing the I-beam-to-CHS-column connection type that exhibited the best mechanical behavior in the past researches, several issues still need to be faced in order to define an appropriate fabrication process and to better characterize the behavior of the I-beam-to-CHS-column connection. For these purposes, in the presently exposed research, preliminary practical, numerical and theoretical studies are conducted to confirm the mechanical and technological advantages previously reported, and to understand the global and local behavior of the passing-through tubular column connections in case of both vertical and horizontal loadings acting on the structure.
Considering the analyzed aspects inherent the practical realization and the mechanical behavior of the I-beam-to-CHS-column with passing elements, new joint solutions are proposed for both steel and composite structures. Afterwards, the proposed joint typologies are experimentally tested in order to have information on their mechanical behavior. On the basis of the behavior exhibited in the tests, mechanical models for steel and composite joints are developed with the aim of drafting practical methods for the definition of design forces acting on the singular components, and global elastic stiffness and strength of the joints.

Benjamin Mays was a groundbreaking religious intellectual whose theological perspective was shaped by world travel. His work and travel in the 1930s show how the international roots of the civil rights movement were fed by various intellectual streams including theological liberalism, a radical tradition of black God-talk, and the “Howard School,” the extraordinary collection of intellectuals at Howard University during this period. His exposure to India and his later work with the international ecumenical movement revealed to Mays connections between American racism and the experiences of imperialism and colonialism. A Christian theologian, he outlined a justice-oriented black social Christianity, interested in and responsive to social realities. He also demonstrated that comparative religious studies would be an essential tool for American Christians who wanted to use liberative lessons from other cultures and religious traditions in the U.S. context.

AbstractThis paper presents research on the impact of a plan to change the salt-fresh water separation system at the Krammer locks in the Netherlands. This lock complex forms the connection for inland navigation between the Eastern Scheldt estuary and the hinterland. The new salt-fresh system will include bubble screens at both lockheads and an additional flushing discharge through the lock chambers and a neighbouring flushing sluice. The interaction between water management, salt management, ecology requirements and navigational requirements has been accounted for with the aid of WANDA-Locks and Delft 3D simulations. The effect of expected sea level rise on the performance of the new proposed new system is also modelled. The modelling efforts show that the new system should be able to keep the salt concentration of the fresh water lake Volkerak-Zoom within the required limits for the duration of the system’s technical lifespan. The modelling approach is able to tune the operation of the lock to the hydraulic conditions of each lockage and within the seasonal restrictions on the water management of the region, giving for each situation the required air discharge for the bubble screens and the flushing discharge. This operation has also been designed to remain safe for the vessels passing through the lock complex.

Storytelling, it can be argued, is an essential element of the archaeologist’s craft. It is because of the necessity for storytelling that archaeology has one foot in the arts and the other in the sciences. Storytelling is more than interpretation borne of observation and the gathering and testing of evidence. It inevitably brings us as individuals into the reconstructions of the past that we assemble during the course of our work. Yet while it is inevitable that we ‘bring to the ‘‘facts’’ our feelings’, supposition, hypothesis, and theory are not enough. Theoretical constructs are necessary, yet archaeologists are engaged in a constant search to find replacements for those that have failed. Archaeologists, professional and amateur alike, have long agreed in principle that acceptable practice demands good data, well collected, and accurately recorded in order to lend credibility to interpretation. An empirical approach to archaeological research relies on the recording of observable manifestations of culture, reasoning backwards from phenomenon to mechanism. This method of exploring human behaviour directly through observed evidence is not always in vogue but is more satisfying to some archaeologists than juggling conceptual abstractions. Archaeologists are individuals, possessed of distinctive personalities, talents and inclinations. We work differently, see differently, feel differently, but for all that we have a bond of commonality—we all understand imperfectly. Honest dispute engenders scrutiny, inspires exploration and promotes progress in a Weld of investigation in which understanding is imperfect and veriWcation elusive. Debate and challenge are key tools in the advancement of archaeological enquiry and the profession demands that, in the interests of progress, we cast ourselves constantly in the role of devil’s advocate. Honesty dictates, however, that we also acknowledge the sources of our inspiration, the ‘giants’ on whose shoulders we have stood in our search for the new horizons, the building blocks we have used as the basis of our research. Underpinning fruitful research is data, the record of the evidence, in whatever form it takes—the archives of unpublished fieldwork, the mountain of ‘grey literature’ that grows with each passing year, the finds and manuscripts under the bed, the published reports.

This chapter focuses on the revolutionary connections between Chile and Algeria during the years 1961-1978. It starts at the beginning of the 1960s when the first extensive references to the Algerian War appear in the Chilean Left-Wing Press and in the reports of the Chilean Ministry of Foreign Affairs and ends with Boumediene’s passing in 1978, which closes the socialist parenthesis in Algeria. It describes the conditions of possibility that underlie the revolutionary connections between Chile and Algeria and thus, the revolutionary cosmopolitanism through the examination of 1° the agents, 2° the places and spaces where those links are created and maintained and 3° the ideas. These three elements are constitutive of a new revolutionary universalism, which allows a political meaning to be given to the diplomatic relations between Chile and Algeria from 1970 onwards.

Through an examination of the experiences of Castillar Lupe dy Cazaril, protagonist of Lois McMaster Bujold’s The Curse of Chalion, this chapter argues that the novel mirrors academic and advocacy agendas on the topics of passing, sexuality, and care, while ultimately relating to emerging perspectives from queer disability studies critiques of normalcy. The chapter engages with The Curse of Chalion as a text that illustrates and contributes to theoretical and activist work on disability in relation to vulnerability and cure, through the multiple meanings of Cazaril’s ‘holy pain’. The chapter shows how, in its overarching concern with embodiment through Cazaril’s physical suffering, fatigue, chronic illness, and rehabilitation, Bujold’s speculative narrative aligns with recent disability studies and disability justice frameworks that hold space for multiple, nuanced perspectives on these issues, inviting examination of the connections between the bodily and social dimensions of disability.

This chapter examines the underappreciated impact of Garveyism in shaping Liberian politics and life during the 1970s. This work was spearheaded by Rev. Clarence W. Harding Jr., a dynamic Chicago-born African American leader, who relocated to Monrovia in 1966 and headed the local division of the Universal Negro Improvement Association (UNIA) until his passing in 1978. Through the local division, and through the Marcus Garvey Memorial Institute, a UNIA-affiliated elementary and secondary school, Harding successfully disseminated the principles of Garveyism widely among working-class and indigenous Liberians living in Monrovia and collaborated with the emergent Movement for Justice in Africa. In tracing Harding’s work in Liberia, the chapter also highlights connections between Liberia and the U.S. Midwest—or what the author has fashioned as the “diasporic Midwest.”

This chapter examines the presence of Muslim envoys in France as an intentional political act from France's periphery that thrust concerns about France's global position—the very substance of royal authority—to the fore. Those concerns were reflected and refracted in the exploding pamphlet literature, images, and newspapers of the period leading up to the Estates General and in the “crisis of representation” that emerged after the Bastille fell in July 1789. The chapter shows how the “Muslim question” appeared in many different forms in the pamphlet war of 1788–1789. In fact, as a result of the changing geopolitical circumstances, Muslims were indeed passing through Paris, and some had real connections to the revolutionary ferment. These figures of real—and already politicized—Muslims were appropriated, caricatured, and ventriloquized in the pamphlet literature and on the stage.

A life cannot be dissociated from its forms (its ways, regimes, spaces, and rhythms) for these forms are also ideas of what life should be. This question is keenly felt today, especially in our ways of experiencing politics: we need ‘other sorts of life’, ‘other ways of living’, other rhythms and connections. Yet these phrases are often emptied of their meaning: they are the stock-in-trade of advertising, which allows us to dream of passing from one lifestyle to another without regard for the ethical complexity of what Pavese called ‘the business of living’. Roland Barthes helps us here. Right from his sanatorium years, and all that it cost him to become aware, so young, of the life made for us by daily routines, food, the weather, our ways of relating to others, and through to La Préparation du roman (which reflected on how everyday life must be organised to lead to a literary work), Barthes was always conscious of the seriousness of what the forms of living entail, in all their precision and detail. This chapter tracks the constancy of this conviction in Barthes’s trajectory, from the early sanatorium correspondence to Comment vivre ensemble and Journal de deuil.

Texto completoResumen
The anatomy of the orbital vascular bed is complex, with tremendous individual variation. The main arterial supply to the orbit is from the ophthalmic artery, a branch of the internal carotid artery. The external carotid artery normally contributes only to a small extent. However, there are a number of orbital branches of the ophthalmic artery that anastomose with adjacent branches from the external carotid artery, creating important anastomotic communications between the internal and external carotid arterial systems. The venous drainage of the orbit occurs mainly via two ophthalmic veins (superior and inferior) that extend to the cavernous sinus, but there are also connections with the pterygoid plexus of veins, as well as some more anteriorly through the angular vein and the infraorbital vein to the facial vein. A working knowledge of the orbital vasculature and lymphatic systems is important during orbital, extraocular, or ocular surgery. Knowing the anatomy of the blood supply helps one avoid injury to the arteries and veins during operative procedures within the orbit or the eyelid. Inadvertent injury to the vasculature not only distorts the anatomy and disrupts a landmark but also prolongs the surgery and might compromise blood flow to an important orbital or ocular structure. Upon entering the cranium, the internal carotid artery passes through the petrous portion of the temporal bone in the carotid canal and enters the cavernous sinus and middle cranial fossa through the superior part of the forame lacerum . It proceeds forward in the cavernous sinus with the abducens nerve along its side. There it is surrounded by sympathetic nerve fibers (the carotid plexus ) derived from the superior cervical ganglion. It then makes an upward S-shaped turn to form the carotid siphon , passing just medial to the oculomotor, trochlear, and ophthalmic nerves (V1). After turning superiorly in the anterior cavernous sinus, the carotid artery perforates the dura at the medial aspect of the anterior clinoid process and turns posteriorly, inferior to the optic nerve.

Video games do not live in a bubble of just the game, they also exist within the larger society, and because of that existence within society, there is a connection with different governments. The largest connection that video games have with government is through copyright protection, as is afforded to other pieces of media and art. Along with this comes talk of censorship and labeling. Video games are also moving into new realms of connection with governments with the rise of eSports. South Korea is one of the most influential when it comes to connection between governments and video games, passing many different laws and having different policies that are connected to video games. This chapter explores video games and government.

Replaceable fuses as coupling elements, with detailed composite connections, can state the steel and concrete hybrid structures to be one of the best alternatives for a more feasible and easy repairable earthquake-proof structure. Therefore, an efficient composite connection for a newly suggested Hybrid Coupled Wall (HCW) system, consisting of a reinforced concrete shear wall coupled with steel side columns via dissipative steel shear links, is studied in this paper. The steel shear links are connected to a steel profile, embedded or passing through the RC wall. This embedded part should be so designed that the damage always occurs on the steel shear links (fuses) prior to minimal damage in the RC wall and embedded connection. The emphasis is on characterizing a suitable “steel link + embedded composite connection within the RC wall” configuration and calculate an appropriate embedment length while concentrating the seismic damage to the replaceable steel links. To this purpose, two joint configurations are designed through a capacity based approach, namely “partly embedded” and “passing through” steel beam connection and are examined through detailed FE analyses. A parametric study was also carried out to provide sufficient evidence towards the design considerations proposed in this study, in terms of strength, stiffness and bearing strength within the embedded connection.

Transportation vehicles traveling on busy roads and highways waste an appreciable amount of their kinetic energy. The lost energy dissipation is due to many factors such as: the friction due to braking, the friction of the tires on the road, the friction of the vehicle body against the surrounding air, and the friction due to the engine’s moving parts. In an effort to save some of this lost energy, it is possible to harvest it through pneumatic and mechanical devices built into the road, especially on highly traffic highways. With over 1 billion cars in the world, there is a huge potential for tapping into the lost energy, and harvesting it for another use. This technical paper focuses on designing a pneumatic and mechanical system that collects the lost kinetic energy of multiple passing cars. A new energy harvesting system utilizing pneumatic and mechanical components has been developed. In this system, a vehicle’s tires pass over a pneumatic manifold system equipped with exciter keys. These keys are depressed and activate a pneumatic system to compress air. Each exciter key is coupled to a connecting rod and piston assembly. The compressed air generated by many exciter keys is then collected in an air tank and channeled to a pneumatic motor. The pneumatic motor transmits then a rotational motion to an electricity generator that produces electric energy. The electric energy can be stored into a series of batteries. The modular pneumatic manifold systems would be located where car drivers encounter deceleration ramps, when approaching a stop sign, or entering a toll booth plaza, etc. The pneumatic system was designed using a computer drawing CAD software. The vehicle’s kinetic energy losses are thoroughly analyzed and their distribution is comprehensively determined using the first principle of thermodynamics, and the thermodynamics theory for compressed air. Energy losses to the system keys and springs, and different friction losses are also determined. A pneumatic model of the manifold, and piping connections to the air tank has been programmed using a pneumatic software for modeling and simulation. An economic viability study of such systems has also been performed. Parameters such as the number of passing cars and the number of strokes on the exciter keys necessary to fill an air tank are determined. A physical prototype of the modular manifold has been built, and experimental measurements are expected to be performed in an upcoming second phase of the project. It is envisioned that such harvesting energy systems can be used to produce energy locally in remote road areas to power stop lights, or street lights. This type of system can also be adapted to be used with other transportation systems such as trains and buses to produce electricity for their respective stations when traffic is heavy.

Texto completoResumen
The performance of a centrifugal compressor is usually defined by its head versus flow map, limited by the surge and stall regions. This map is critical to assess the operating range of a compressor for both steady state and transient system scenarios. However, the compressor map does not provide a complete picture on how the compressor will respond to rapid transient inputs and how its surge behavior is affected by these events. Specifically, the response of the compressor to rapid transient events, such as single or multiple (periodic) pressure pulses, is also a function of the compressor’s upstream and downstream piping system’s acoustic response and impedance characteristics. This unique response phenomenon was first described in the 1970s and came to be known as the “Compressor Dynamic Response (CDR) Theory”. CDR Theory explains how pulsations are amplified or reduced by a compression system’s acoustic response characteristic superimposed on the compressor head-flow map. Although the CDR Theory explained the impact of the nearby piping system on the compressor surge and pulsation amplification, it provided only limited usefulness as a quantitative analysis tool, mainly due to the lack of computational numerical tools available at the time. To fully analyze pulsating flows in complex centrifugal compressor suction and discharge header piping systems, the principles of the CDR Theory should be implemented in a dynamic flow model to quantify the magnitude of the amplifications of pressure pulses near the surge region. When designing centrifugal compressor stations within a transmission piping system, it is critically important to have a full understanding of the impact of the station’s piping system on compressor dynamic behavior. For example, if a compressor system’s piping impedance amplifies the suction side pulsations, the compressor’s operating range will be severely limited and will produce unacceptable discharge piping vibrations. Whereas it is usually desirable to limit the downstream volume between the compressor discharge and the check valve to reduce the potential for transient surge events, a small discharge volume results in high piping impedance. This will amplify pressure pulsations passing through the compressor. The small downstream volume provides limited ability for any transient peak (such as a pressure pulse) passing through the compressor to be absorbed quickly, and an amplified discharge pressure spike will be the result. Also, if any periodic pressure excitation from upstream vortex shedding or any other continuously varying flow disturbance couples with a pipe resonance length, the result can be high fluctuations of the compressor operating point on its speed line, effectively resulting in a reduced operating range and higher than expected surge margin (surge line moves to the right). Both acoustic resonance and system impedance are functions of pipe friction, pipe and header interface connections, valve/elbow locations, pipe diameter, and valve coefficients, i.e., the entire piping system connected to the compressor. Thus, a careful acoustic and impedance design review of a compressor station design should be performed to avoid impacting the operating range of the machine. This paper describes the methodology of such a design review using modern pulsation analysis software. Examples and parametric studies are presented that demonstrate the impact of system impedance and piping acoustics on the dynamic operating response of the compressor in a typical compressor station. Some recommendations to reduce the risk of pulsation amplification and unsteady operation are also provided.

The purpose of this paper is to present the process of designing and developing a dynamic interface for an archaeological management system, with advanced possibilities of viewing, adding and modifying standardized sheets, created at a certain place, based on the coordinates extracted from the map. The main goal of the paper is to present the conception and implementing of the archeological management platform, along with the functionalities behind the composing elements and the classes which help in the process of data manipulation and database connections. This developing process also involved the integration of three modules. The developing process of these modules was based on the Three Layer Architecture and every one of the modules was designed separately. The database is the foundation of this project, because without it the main functionalities of this website wouldn't work. It was developed using the SQL scripting language with the help of the Microsoft SQL Server 2012 development kit. The initial design of its components was based on a standardized model of an analytical sheet of inventory, provided by the Architecture, Restoration and Archaeology Association. This analytical sheet is a standardized version which contains certain characteristic information associated with the archaeological site. The second module which help to the creation of this project is represented by the map, developed with the help of the Google Maps API. The technology provided by Google is highly complex, it offers us a lot of customizable functionalities, extensive documentation and the process of adding new functionalities is possible with the help of JavaScript in a relative simple way. The integration of the map within the interface it's possible with the help of a simple link-based reference, in order to get the needed data from the Google servers. Within this link, we have to summon a key, dynamically created in connection with our specified account. This is called an API key and its usage is that of counting the information traffic. If a certain traffic limit is reached or surpassed it is supposed that the application is not used in personal means and thus certain payroll may apply. In order to use the existing functions or overwrite them, we have to include another link referral to a JavaScript file, where some of the functionalities were already added by a teammate. Completion of this project involved passing through all the stages related to the development of a suitable software product, from its use planning, maintenance and creation of appropriate documentation, involving theoretical knowledge, technology and development. The original contribution of the papers consists in its interdisciplinary nature, given the scope of platform developed, able to provide deepen related information, closely related to the archeology, history and cultural heritage study. The application is in its prototype version and has great potential as a major exploit in the future.

Texto completoResumen
Abstract In the failure analysis of semiconductors, layout analysis to pick up suspect nets is getting to be a time consuming work due to finer wiring pitch and multi-layer structure. This article proposes a failure analysis navigation system (FA-Navigation System), which can make it easier to extract the nets passing through the signals detected by the hardware analysis tool, such as emission microscopes or OBIRCH analysis tools. It introduces the functions of the system and shows some case studies in actual failure analyses. The IDDQ fault diagnosis is especially useful for case studies. The result of the software diagnosis can be loaded in the analysis window of the FA-navigation system, and the system correlates the result to the nets extracted by the hardware analysis and displays coincident nets in a sorted manner to make the failure analysis easier.

<p>The Boomerang and Jungle pedestrian bridges form part of a new pedestrian and cycle path, passing from the centre of Oslo through an urban forest and over the Outer Ring Road. The main goal for the design team was to integrate the bridges’ architecture within the natural environment and to cause the minimum impact during the construction period. The 85m long Boomerang bridge, named after its shape in plan, crosses the ring road with a 22.5m span, whose traffic was maintained throughout the construction period. In total the bridge comprises of four spans, with a continuous steel box girder of asymmetric cross-section. The bridge and the railings are fabricated from Cor-ten weathering steel to avoid the need for painting and to minimise future maintenance. The Jungle Pedestrian bridge is a simple suspension bridge spanning 36m over a small river. The main structural elements are parabolic, locked coil cables, four at deck level and two at handrail level. The deck is formed from slip-resistant perforated steel panels, supported off a transversely stiff steel framing system. The design intent was to maximize the use of prefabricated lightweight elements to facilitate the bridge erection and minimize the impact on the natural environment. Due to the lightness of the bridge a detailed analysis of the accelerations due to pedestrian-induced vibrations was performed to assess the comfort level for bridge users. The project won in 2017 the Norwegian Steel Construction Award and was nominated for World Architecture News’ Best Bridge Award 2017.</p>

Experiments are presented to quantify the convective heat transfer and the hydrodynamic loss that is obtained by forcing water through blocks of porous carbon foam (PCF) heated from one side. The experiments were conducted in a small-scale water tunnel instrumented to measure the pressure drop and the temperature rise of the water passing through the blocks and the base temperature and heat flux into the foam block. In comparison to similar porosity aluminum foam, the present results indicate that the pressure drop across the porous carbon foam is higher due to the large hydrodynamic loss associated with the cell windows connecting the pores, but the heat transfer performance suggests that there may be a significant advantage to using PCF over aluminum foam for extended surface convection elements in recuperators and electronic cooling devices.

En ASME Turbo Expo 2018: Turbomachinery Technical Conference and Exposition. American Society of Mechanical Engineers, 2018. http://dx.doi.org/10.1115/gt2018-76145.
Texto completoResumen
The spike-type rotating stall (RS) inception inside the vaned-diffuser, which seriously restricts the performance range and brings the problems of blade fatigue, still seems to be a ‘mystery’ since its randomness. The paper intends to explain the mechanisms of this stall inception. To quantitatively assess the critical unsteady behavior to the initiation of RS inception, the transient measurement characterizes the process falling into the RS through the parameter of ‘blade passing irregularity’. The underlying vortex disturbance, related to the growing of the flow complexity and the final spike-type precursor, is further revealed by the full-annulus simulation. The results show the propagation principle of the vortexes from the design to the stall inception point, reflected by the distribution of ‘blade passing irregularity’. The performance change of different sub-components due to the vortex behavior is presented. At the RS limit, the sudden ramp-up of the ‘blade passing irregularity’ near the leading edge (LE), accompanied with the drop of the static pressure rise in the sub-component between the semi-vaneless and throat, corresponds to the spike-type inception in the form of a clockwise vortex connecting the suction side of the diffuser vane and the pressure side of the adjacent vane. Besides, when approaching the spike-type inception point, the couple effect of the growing potential of the diffuser vane and the enhanced vortex disturbance at the impeller outlet degrades the diffuser inlet flow.

En 12th international conference on ‘Advances in Steel-Concrete Composite Structures’ - ASCCS 2018. Valencia: Universitat Politècnica València, 2018. http://dx.doi.org/10.4995/asccs2018.2018.6963.
Texto completoResumen
Composite slim floor beams comprise a steel section embedded in a concrete slab, offering the advantages of a steel-concrete composite structure combined with a reduced floor depth. Several mechanisms contribute to the shear connection in this type of beam, such as headed studs, friction and clamping effects and the using of reinforcement bars passing through holes in the steel beam web. However, to date, nobody has systematically identified these mechanisms and Eurocode 4 does not provide specific design guidance for slim floor beams. Hence, a series of shear beam tests and flexural beam tests were carried out in order to assess the degree of shear connection and connector capacity in these beams. The test set-up is described including different arrangements of shear connectors for each specimen. The paper presents the findings from the flexural beam tests. The results are compared with those from the previous shear beam tests. Numerical models will be developed in future to extend the data and include a wider range of parameters. The data will also be used to improve understanding of this type of beam and will lead to the provision of specific design guidelines for slim floor beams.

Texto completoResumen
Many small cities and towns in rural states such as Indiana are crossed by arterial highways. The local traffic on these roads, particularly vulnerable road users, face the excessive risk of injury and death. This danger is amplified with local land development, driveways, and on-street parking in town centers. This report presents an Indiana study of the speeding problem on arterial roads passing through small communities. Past research on various countermeasures suitable for the studied conditions were identified and the connection between speed reduction and safety improvements was investigated in a sample of Indiana small towns. Promising speed-reduction measures include speed feedback signs and converging chevrons with speed limit legends marked on the pavement. Point-to-point enforcement is a modern and highly effective alternative that may be applicable on highways passing small towns if the through traffic prevails with limited interruptions. This report provides a method of evaluating the benefits of speed reduction in the studied conditions where the risk of severe injury and fatality is excessive to road users while the frequency of crashes is low. The method includes the proactive estimation of the economic benefit. The results indicate that both the local and through traffic on highways passing a small town benefit considerably from speed reduction even after accounting for the loss of time. An Excel spreadsheet developed in the study facilitates the calculations.
