Full textAbstract:
Rose windows are of special significance in gothic cathedrals. These are large circular windows. They are also exquisite works of masonry. In terms of their construction, the sectioning of the circle into smaller, equal segments presented a particular challenge. The division of a circle into equal segments or the ratio between the diameter and the circumference was an old mathematical problem, which had practical consequences for architects and masons. Their answers ranged from simple to more complex solutions. Analysis has shown that the segmentation of rosettes was simpler in the early period. It later evolved into more complex segmentation, which was probably also based on anthropometric measuring systems. Perhaps the most complex segmentation of the rosette can be found in the rose windows of the Basilica of Saint Clare and the Basilica of Saint Francis in Assisi, which are presented separately.

The commissioning of the Big Circle Line in Moscow, some sections of which were laid jointly with Chinese underground builders, provided the first experience of interaction with foreign construction contractors on the Moscow Metro. The paper investigates this experience which is of value for the development of such works in the future. The analysis was carried out on the basis of scientific and technical documentation on certain facilities, the progress and results of construction and installation works, and information on other events. The paper describes the facilities where construction and installation works were carried out by joint efforts and shows the peculiarities of interaction between Russian and foreign (Chinese) metro builders on a number of sections of the Big Circle Line of the Moscow Metro. The achieved results are demonstrated by the example of individual underground stations. The study reveals the peculiarities of material and technical support of works on the sections constructed by Chinese construction contractors. The mutual exchange of experience, technologies, and work management practices along with the application of various tunnel boring machines from both countries (Russia and the PRC) has yielded fruitful results, demonstrated the possibility and efficiency of the direct engagement of foreign tunnel builders at Russian sites in close cooperation with their Russian counterparts, and revealed a scheme for rational division of labour, work management, and logistical support of works.

The goal of sustainable construction is to improve the energy efficiency of a building, which today is a challenge for software developers, builders, owners within the constraints of time, cost, provision and resources. Building functional, sustainable, safe, comfortable and easy-to-use buildings will increase consumer demand. The problem of implementing sustainable construction lies in the division of responsibilities and tasks from the relevant specialists. This article explores the role of Building Information Modeling (BIM) in reducing fragmentation among professionals at every stage of construction. The possibility of using a virtual storage of information using BIM is analyzed, which provides easy access to data and their exchange in real time. Thus, BIM provides a professional platform for working in an integrated environment at any stage of the building construction process. When analyzing Russian and foreign sourcesthe prerequisites are being created for the future research required to generate improvements towards sustainable construction.

Full textAbstract:
The machine tool industry is comprised of high-tech production and processing equipment that combines various software and hardware functions such as machinery, motor, optoelectronics, new materials and automatic control. The demands for machine tools has been continuously developed and expanded, from the early mold and home appliance industries to today’s automotive, aerospace and 3C industries. Furthermore, it has gradually extended to emerging industries such as biomedical, green energy and space, indicating that the machine tool industry plays an important role in overall national industries. Taiwan’s Machine Tool Industry is world-renowned and enjoys a complete vertical division of labor. Based on the production and sales statistics in 2016 and 2017 issued by Taiwan Machine Tool & Accessory Builders’ Association (2018), this study conducts comparison, analysis and exploration on the machine tool export model and major exporting countries, output conclusions and offer relevant recommendations on policy formulation and management that are proposed for the government and industry respectively.

Full textAbstract:
In the summer of 2021, users on the livestreaming platform Twitch were targeted by a wave of "hate raids," a form of attack that overwhelms a streamer's chatroom with hateful messages, often through the use of bots and automation. Using a mixed-methods approach, we combine a quantitative measurement of attacks across the platform with interviews of streamers and third-party bot developers. We present evidence that confirms that some hate raids were highly-targeted, hate-driven attacks, but we also observe another mode of hate raid similar to networked harassment and specific forms of subcultural trolling. We show that the streamers who self-identify as LGBTQ+ and/or Black were disproportionately targeted and that hate raid messages were most commonly rooted in anti-Black racism and antisemitism. We also document how these attacks elicited rapid community responses in both bolstering reactive moderation and developing proactive mitigations for future attacks. We conclude by discussing how platforms can better prepare for attacks and protect at-risk communities while considering the division of labor between community moderators, tool-builders, and platforms.

Full textAbstract:
The article presents the newly discovered archival data relating to the marangoni and lapicide recorded in Trogir’s notarial books between 1420 and 1450 (see the Appendix: Overview of archival records mentioning lapicide and marangoni in Trogir from 1420 to 1450). It also includes few already known data published by Ivan Kukuljević Sakcinski, Cvito Fisković and Danko Zelić, as well as those recorded by Ivan Lucić and Pavao Andreis in their Trogir history books (from the 17th century), and the records from the canonical visitation of Bishop Didak Manola. The sources consist of a handful of documents recording the commissions, and a large number of documents through which marangoni and lapicide arranged their private affairs or acted as witnesses. Out of sixty six recorded, thirty four were marangoni. Among these, twenty five were from Trogir and the same can be assumed for six of them whose origin was not mentioned, one was from Šibenik and two from Zadar. The overall number illustrates the need for such craftsmen in contemporary Trogir: the variety of tasks marangoni could perform was extremely wide and ranged from wood carving to the construction of stone buildings. However, it is likely that individual marangoni tended to specialize only in one of these fields. The documents mention twenty seven lapicide, six of which were from Trogir, four of unknown origin, three were mentioned as living in Trogir without an indication of their origin, five were from Venice, three from Dubrovnik, two from Šibenik, and one from Split, Zadar, Adria, Bosnia and Hvar respectively. Through the analysis of the collected information and how it relates to the records about contemporary building projects such as new structures and the remodellings of old ones, the article aims to outline their different roles in the building works in Trogir from 1420 to 1450. The projects of that time included the construction of Dominican monastery in the suburb and the Franciscan one on the mainland. They both were demolished by the citizens attempting to improve the city defence in the early 15th century. During the attack of the Venetian fleet in 1420 numerous buildings were damaged and in need for reparations that often led to their remodelling as well. That was the case with the Benedictine monastery in the town centre and many private houses and especially included the renovation of the Cathedral and the continuation of the building works on it. Following the introduction of Venetian rule to Trogir in 1420, a number of new structures and repair works had to be done in the newly created circumstances the aim of which was the consolidation of Venetian presence. Among these, the most important projects were the construction of a citadel for Venetian military crew, also known as the Kamerlengo, and the remodelling of the municipal palace. The whole new Observant Dominican monastery and the Church of the Holy Cross were constructed as well. The preserved archival data, however, cannot give us the clear answers of all the builders that were employed on those works.Among the recorded marangoni and lapicide, the most capable builders can be identified in two ways: through the contracts for the building of vaults, that is, the construction of vaulted spaces, and through the use of the title of protomagister regardless of whether, as E. Hilje explained, they refer to a builder who is also a designer/an architect or a builder who is simultaneously a foreman/site manager, or even the leading figure/authority chosen by the local craftsmen among themselves. Those master builders knew about the construction, and this knowledge enabled them to take on demanding tasks and roles. On that level, their primary education did not matter: vaults were constructed by both marangoni and lapicide and both of them had the protomagister titles indicating their tasks and roles. An additional criterion should be taken into account when attempting to identify the most capable master builders, that is, the training contracts which imply that the teacher was not only skilled but busy because otherwise he could not have been in a position to train an apprentice during all work phases or provide him with food and lodgings.Among the marangoni and lapicide from Trogir (meaning being born, living and working in that town) there were those who were capable of producing drawings, organizing and managing a building site, carrying out demanding constructions and carving architectural sculpture, but also those who were responsible for the building works considered minor but necessary. The reason for the influx of a large number of craftsmen from other towns – nineteen of them were lapicide, while two out of three marangoni were definitely responsible for demanding constructions in stone – lies in the scope of the building projects in Trogir between 1420 and 1450. Even the meagre preserved records relating to specific commissions demonstrate that out of twenty three newcomers, as many as fourteen had work contracts before they arrived and the same can be suggested for another two. This means that they did not arrive in search of a job but were hired beforehand. Although the priority was always given to local builders, that is, to those who had already worked at Trogir, given that the construction of the Kamerlengo and the remodelling of the municipal palace demanded a large number of builders, they were procured by Venetian officials, while the Observant Dominican monks used their connections in Šibenik and Dubrovnik. Once in Trogir, some master builders accepted other commissions. On the basis of the information about their skills, this article attributes a number of undocumented local works to those masters. At the same time, we do not have enough information about the work of the carpenters and stonemasons native to Trogir, especially the work of the three recorded protomagistri. We have established that the reason for this, both in Trogir and in other towns, was the well-known and widespread (particularly in Trogir) practice of writing internal acknowledgements of debt and confirmations instead of recording contracts in notarial ledgers. Because of this, we have no information about the organization and division of tasks at building sites. Only one document testifies to the fact that the lapicide and marangoni who took on the contracts for the construction of buildings had to guarantee that the building process would be done properly and with a set time frame. This, however, did not mean that they themselves carried out the works; instead, they delegated, supervised, organized and co-ordinated the tasks. Given that we know of no other similar subcontract (most of them were probably internal as well and not recorded in notarial books), it can only be said that apprentices took part in the building projects which were contracted by the masters who were training them.Therefore, the analysis of the collected information does not provide clear answers to the numerous questions regarding the output and authorship of the master builders, some of which were already posed by Lj. Karaman (1933). Instead, it opens up new problems which we have addressed by arguing for a number of hypotheses on the basis of the available information. We have suggested that several master builders remained in Trogir for a longer period of time than the one recorded in the surviving documents, and one should also bear in mind that the preserved sources probably do not contain records about every single stonemason or carpenter who was active in Trogir at the time. The sources illustrate the main reasons lying behind the arrival of builders, stonemasons and carpenters from other towns but also that their place in the hierarchy of contemporary marangoni and lapicide depended on their skills and knowledge. It can be safely assumed that, depending on their abilities, all the builders, stonemasons and carpenters listed in this article took part in the building campaigns and works (taken in its broadest sense) and by doing so, contributed to the construction of building projects in Trogir between 1420 and 1450.

Full textAbstract:
This paper fo cuses on social conflicts in the field of work during the privatization processes in Socialist Federative Republic of Yugoslavia and its successor states, including Bosnia and Herzegovina. During the, often dubious, privatization processes, large industrial complexes and leading socially owned companies were dismantled, broken into pieces and sold or bankrupted. For majority of workers, considered as builders, ?owners? and drivers of the companies during the socialist era, privatization resulted in job loss, impoverishment, and dispossession of ownership and of the opportunity to work at companies they considered as ?their own?. Based on the multiple case studies, I analyse workers? narratives on privatization processes, including the role of workers and unions in those processes. Triangulating the data collected from the factory newspapers, media, available archives and documents, including interviews with (former) workers of three industrial complexes (Rudi Cajavec, Energoinvest and Aluminij), research results show narratives of privatization as theft, powerlessness of workers within these processes, politics of fear, as well as workers? disunity. Research results also show that the strategies and tactics used by political, ethno-national and economic elites to pacify workers? uprising and union actions, resulted in shattering the workers? organized actions, division of workers and union fragmentation.

Lenin is a unique biopolitical phenomenon. Lenin’s body, on the one hand, turns into a political symbol, and the history of the management of Lenin’s corporeality in the literal and figurative (symbolic) sense has been going on for almost 100 years. On theother hand, Lenin, or rather his cultural simulacra (in literature, painting, cinema, sculpture), turn out to be agents (post-agents) controlling the bodies and time of Soviet/Russian citizens. The purpose of the article: to outline the main directions ofthe analysis of the biopolitical potential of Lenin’s physicality. Results: the main contexts within which it is possible to talk about Lenin’s body as a biopolitical technology are identified. On the one hand, Lenin (or rather his mummy) turns out to be a phenomenon of a single case of biopolitical attention. As Jean Baudrillard wrote, the control of life and death, as well as the division into the living and the dead, the manipulation of death is the basis of any power, and further "here, at this outpostof death, power is formed." On the other hand, the representation of Lenin’s physicality in stories for children can be considered as a biopolitical technology that instills correct bodily techniques in young builders of communism.

Student discipline in the classroom is an effort to build the character of student discipline. However, in general the rules are made not too heeded the students so that gradually affect the efforts to improve the quality of Education. This study aims to find the problem of why students are not enthusiastic about their own discipline and then find a solution partispatif with students. The study was conducted at MTs Khaudul Ulum Penajung. The study used an action approach with steps in the form of SWOT analysis, finding problems related to the implementation of student discipline, discussing together the solution, drawing up a solution action plan, organizing to socialize it, then carrying out joint action,and finally reflection evaluating together also for further improvement. The parties involved are the head of the madrasah, deputy head of Student Affairs, the Student Council builders, and student council managers. The management theory used is the theory of plan-do-check-act (PDCA). The results of this action research are: (a)the finding of priority issues stemming from the lack of discipline of students in the Classroom, (b)planned participatory joint action on the manufacture of student rules, (c)The Division of tasks and socialization, (d)the holding of Joint Action for the manufacture of student rules, and (e) reflection to evaluate the implementation of the action. Recommendations/ suggestions: (a)this action activity is developed continuously, and (b)further actions are more directed to the purpose of improving the quality of madrasah. Keywords: action research, quality improvement, student discipline

Full textAbstract:
The question of the origin of Whitman’s signature long line remains shrouded in mystery. The renewed attention paid to the early notebooks and poetry manuscripts has enabled scholars to see much more clearly the emergence of that line and to have a better idea of its rough chronology. But what of this line’s inspiration? Its animating impulse? Where does it come from? And why? The evidence at hand does not permit conclusive answers to these and related questions. Still, in this chapter, the possibility that the KJB played a role in shaping Whitman’s ideas about his emerging line is probed. In particular, the central argument if the chapter builds on an insight of George Saintsbury who, in a review of the 1871(-72) edition of Leaves, calls attention to the likeness of Whitman’s line to “the verse divisions of the English Bible, especially in the poetical books.” A number of aspects of Whitman’s mature line (e.g., its variability, range of lengths, typical shapes and character, and content) become more clearly comparable to the Bible when thought through in light of Saintsbury’s appreciation of the significance of the actual “verse divisions of the English Bible.” Along the way the chronological development of Whitman’s line is sketched, emphasizing the poet’s break with meter as key to opening the possibility for a longer line. Other possible means by which knowledge about the Bible beyond direct readerly encounters may have been mediated to Whitman (such as the poetry of James Macpherson and Martin Farquhar Tupper) are also considered.

Full textAbstract:
AbstractCross-platform power/performance prediction is becoming increasingly important due to the rapid development and variety of software and hardware architectures in an era of heterogeneous multi-core. However, accurate power/performance prediction is faced with an obstacle caused by the large gap between architectures, which is often overcome by laborious and time-consuming fine-grained program profiling on the target platform. To overcome these problems, this paper introduces $$CP^3$$ C P 3 , a hierarchical Cross-platform Power/Performance Prediction framework, which focuses on utilizing architecture differences to migrate built models to target platforms. The core of $$CP^3$$ C P 3 is the three-step hierarchical transfer learning approach, hierarchical division, partial transfer learning, and model fusion, respectively. $$CP^3$$ C P 3 firstly builds a power/performance model on the source platform, then rebuilds it with the reduced training data on the target platform, and finally obtains a cross-platform model. We validate the effectiveness of $$CP^3$$ C P 3 using a group of benchmarks on X86- and ARM-based platforms that use three different types of commonly used processors. Evaluation results show that when applying $$CP^3$$ C P 3 , only 1% of the baseline training data is required to achieve high cross-platform prediction accuracy, with power prediction error being only 0.65%, and performance prediction error being only 4.64%.

Full textAbstract:
The ongoing digital transformation is facilitating the production, sharing, use and exploitation of an ever increasing amount of data. This phenomenon is stimulating the demand for data-driven decision-making. Regarding tourism, we are moving towards the production of data reflecting a sustainability perspective. The UN World Tourism Organization (UNWTO), in partnership with the UN Statistics Division, launched in 2015 the Measuring the Sustainability of Tourism (MST) initiative aiming at developing an international Statistical Framework (SF-MST) for measuring the role of tourism in sustainable development, including economic, environmental and social dimensions. The ambition is to develop a standardized basis for the collection of relevant information at appropriate spatial scales and the integration of statistics on different domains. For this purpose, the perspective of official statistics, characterized by the highest quality possible inasmuch as they are produced in compliance with the UN Fundamental Principles of Official Statistics and the European Statistics Code of Practice, is followed. SF-MST follows an accounting-based approach and sustainability is envisaged to be evaluated by measuring a broad set of capitals (produced, natural, human and social capital) and the flows of related incomes and benefits. SF-MST builds upon existing internationally agreed statistical standards and guidance in relevant areas: this ensures the adoption of a common statistical language across countries. The linking of the Tourism Satellite Account and the System of Environmental-Economic Accounting, both aligned with the UN System of National Accounts, is a central feature of SF-MST. Despite a standard accounting system is not available for social capital, SF-MST enables the integration of the social dimension of tourism’s sustainability in its own multiple capitals-based approach. SF-MST, involving a wide range of agencies and stakeholders, plays a key role in providing an integrated information basis for derivation of indicators and development of data supporting more effective decision-making towards sustainable outcomes.

This chapter discusses the way housewifisation was replaced by working classization to support women's entry into the workforce. The chapter tackles the conceptual division between production and reproduction often made in economic theories attributing sexual inequity to the gendered division of labor. However, according to Marxist feminists, women's reproductive work undergirds capitalist accumulation. The chapter explains the continued shame attached to working women, despite the changes brought by social revolution and war. It elaborates on the national gatherings: the 1959 National Conference of Women Socialist Builders, the National Mothers Congress, and the 1965 Third Congress of the Korean Democratic Women's Union.

Abstract Questioning the usefulness of the distinction between the ‘ethnic’ nations of Eastern and East-Central Europe and the ‘civic’ nations of Western Europe, Rogers Brubaker has offered a more nuanced distinction ‘between state-framed and counter-state understanding of nationhood and forms of nationalism’. In the first instance, a nation is territorially and institutionally ‘framed’ by the state; in the latter it is perceived by nation-builders to be in opposition to some existing state or states. Brubaker’s classification is based on Ernest Gellner’s division of Europe into three main time zones in terms of nation-building.

This chapter builds on the author’s programmatic approach to research in social epistemology, according to which such research involves the systematic investigation of the epistemic significance of other minds. This research program is developed by appeal to the thesis of the Division of Epistemic Labor. After formulating this thesis as a thesis of epistemic dependence, the chapter illustrates several ways in which individual subjects are epistemically dependent on one or more of the members of their community in the process of knowledge acquisition. Such an account supports various conclusions about the cognitively distributed nature of some knowledge acquisition, and the chapter ends with these.

Full textAbstract:
Abstract Chapter 4 builds on previous chapters in which, in all the cases discussed, a deliberator furnishes for the executor a morally problematic purpose; the deliberator is accordingly accountable for that wrong-making feature of the executor’s conduct. It has been assumed so far that the participants in the division of agential labor a) are fully committed to what they’re doing together, b) are not coerced into participating, c) know what it is that they are doing together and why they are doing it. One might worry that the argument for authority-based accountability holds water only given these idealizing assumptions. In what follows, this worry is addressed. The upshot will be that the authority-based accountability survives cases in which the executor—but not necessarily the deliberator—suffers from alienation, coercion, and ignorance.

Exploring the everyday encounters between Chinese managers and Ethiopian laborers on the construction site in Tigray, this chapter challenges depictions of Chinese engagement with Africa as a model imposed on a practice. Chinese workers’ initial expectations of life and work in Ethiopia stand in contrast to the difficulties they face on the ground. Puzzled by the apparent ingratitude of Ethiopians, their lack of cooperation, and, worse, their repeated attempts to sabotage the building work, Chinese road builders are left disenchanted. Firm hopes of helping Ethiopians develop are offset by the bitter taste they experience in the face of repeated pushbacks, not only on the building site but also in the courtroom. Unraveling the intricacies of Chinese-led development in Ethiopia, this chapter discusses internal divisions in the Chinese community, road builders’ vain efforts to fashion Ethiopian laborers, and Chinese narratives of bitterness that address their own perceived lack of agency.

Full textAbstract:
In this short chapter Glissant returns to the idea of orality, now from the point of view of how it has influenced the structure of contemporary writing. To write is to ‘say the world’; to connect our own place with the Whole-World. He claims that the traditional division into literary genres no longer operates, and narrative is no longer dominant. The poet is more important as a builder of langage, i.e., our subjective relation to the language we speak.

When we initially created and refined the first-year Cornerstone courses at Minerva, we evolved a set of shared processes, conventions, and templates to support the process of developing lesson plans for active learning. After devoting two full years of curriculum design effort exclusively to these four courses, we faced the challenge of scaling our course development process to simultaneously design a much larger number of upper-division courses. In order to consistently and efficiently create extraordinary active learning experiences, we started to develop a software-based lesson plan authoring tool that would encapsulate and codify our previously-validated templates and processes. This tool, Course Builder, grew to also support the management and iterative improvement of our full curriculum. By the end of its first semester in use, the combined functionality of Course Builder and the Active Learning Forum allowed us to move beyond the need for a Learning Management System entirely. In this chapter, we introduce the Course Builder curriculum design system. We take a close look at how this technology allows us to collaboratively design, systematically coordinate, and iteratively improve on courses and lesson plans built specifically for active learning.

Full textAbstract:
With intense competition today among builders of large engines the drive to improve technology and reduce engine cost has accelerated. Leading large engine builders have always developed their own techniques to do this. A huge investment has been made in the last 10 years by the automotive industry to further develop technology and large engine builders are now benefiting from these advances. Use is also being made of the longer experience of the automotive engine builders in developing electronics and in meeting emissions legislation. We look at how these techniques are being adapted for marine, locomotive and power generation engines and at the benefits they are bringing. Examples are described from analytical software development, common rail FIE, in cylinder measurements and reliability engineering to production engineering, engine health monitoring and alternative fuels. Further market demands and more stringent regulations are considered because they will force ever more development in an ever reducing time scale. Shorter engine test times are essential. Other ways are being developed to ensure competitive performance and reliability. Future developments in response to these demands are predicted and the effects these may have on large engine design are assessed.

Full textAbstract:
The year 2015 will be a landmark year in locomotive technology in the United States. Effective January 1st of that year, newly-manufactured U.S. line-haul and switch service (freight-and-passenger) locomotives must be manufactured to meet the fifth level of U.S. Environmental Protection Agency (EPA) emissions regulations since 2000. Achieving those emission levels will require aftertreatment technology in some form. Also effective December 31st of that year, U.S. railroads will be required to have in operation (on much of the rail network)1 a federally-mandated Positive Train Control (PTC) technology for collision avoidance. Class I U.S. freight railroads2 by the end of 2015 will have invested an estimated $5.8 billion in PTC technology, with a major emphasis on interoperability of PTC-equipped locomotives between different railroads. An estimated 17,000 locomotives will be retrofitted or equipped with PTC by the end of 2015 and most if not all newly-manufactured locomotives will be PTC equipped after 2015. For perspective, the U.S. freight railroad investment in PTC is roughly what the Class I railroads have spent the past 4–5 years combined on capital expenditures related to infrastructure expansion. This convergence of two new complex locomotive technologies in 2015 will create a large challenge, especially in locomotive maintainability, for freight railroads. Locomotive builders and aftertreatment suppliers must work together to provide Tier 4 locomotives with minimal impact on railroad operations. U.S. diesel locomotives share a common internal combustion engine technology with most Class 8 over-the-road diesel trucks, but the railroad and locomotive environment is very different from the highway truck environment, and a “cookie cutter” approach to replicating diesel truck aftertreatment on locomotives should be avoided. New EPA Tier 4 diesel locomotives should not be viewed as “Tier 2 or Tier 3 locomotives with truck-type exhaust aftertreatment added”. Baseline reliability of current locomotive designs must also be improved to compensate for the added complexities of both exhaust aftertreatment and PTC. This paper is focused toward educating (1) aftertreatment technology manufacturers and system integrators and (2) locomotive design engineers. The emphasis is on assisting them in understanding the operating and maintenance expectations for Tier 4 aftertreatment-equipped line-haul locomotives, from the perspective of a major freight railroad.

In ASME 2012 Internal Combustion Engine Division Fall Technical Conference. American Society of Mechanical Engineers, 2012. http://dx.doi.org/10.1115/icef2012-92067.
Full textAbstract:
The technology drivers for slow speed large bore engines can be summarized as follows: restrictive emission regulations, improvements in reliability, new ship designs and decreasing life cycle costs (fuel efficiency, first cost, maintenance cost). The industry mindset and development experience is traditionally driven by reliability and fuel consumption. The upcoming emission reduction calls for a focus shift and new development processes for the engine builders. The emission reduction increment is substantial and the time is short. Therefore the industry needs fast technology awareness, acceptance and implementation. The new 2-stroke engine generations are subject to continuous performance improvements driven by new and demanding operating conditions. Higher firing pressures are required and result in higher bearing loads and larger bearing sizes. In particular for the cross-head bearing the bearing width will exceeding 400mm. Thus traditional bearing designs no longer meet the requirements. Bearing manufacturers must consequently go to the limits of feasibility. When looking at the performance criteria of bearings for the application in 2-stroke engines, properties like emergency running capabilities, embedability and to certain extend the fatigue properties are vital to the performance of these engines. To meet these demanding requirements a new and extremely robust cross-head bearing design based on tri-metal configuration Steel – Aluminium-Tin 40 - Synthec® for the MAN Diesel & Turbo SE Tier II engine platforms has been developed and successfully tested. The new design is called “Patch-Work-Bearing” and is currently used for long stroke engines with a minimum bore diameter of 400mm. So far, the prefab material for steel backed aluminium based bearings is produced via well-established roll-bonding processes. If it comes to cross-head bearings for the new engine generations with a characteristic bearing diameter to bearing width ratio of approximately 1:1 ordinary processes cannot be used. The process window is already fully exploited with respect to the rolling-mills capability (width and rolling force). Currently in order to produce the needed prefab material a so called explosion bonding process is used, at which the formation of multi-layer materials is based on kinetic blasting energy [1]. Parts with a size of several square meters can be product. Anyway this technology is exceptionally expensive as high safety measures are mandatory and ordinary production facilities are insufficient. It is a single piece production process with many variable process parameters and therefore a stable and high quality level is difficult to achieve. In particular the bonding strength and bonding quality relies on a constant forming process. This paper will focus on a new method to produce prefab material for the production of extra wide cross head-bearings which is not based on the explosion bonding process. The paper gives an insight in the new design of the cross-head bearing and the advantages resulting from that.

Full textAbstract:
This paper discusses a railway specific cognitive radio that builds upon software defined radio (SDR) platforms to adapt the radio based situational awareness. Cognitive Radio incorporates artificial intelligence based algorithms with reconfigurable software-defined radios that enable automatic adjustments of the radio to improve performance and overcome obstacles the radio may confront in the field (i.e. environmental/man-made interference, occupying the same channel as a user with higher priority, etc.). This paper describes the Railway Cognitive Radio (Rail-CR) architecture and illustrates preliminary results in simulation. The proposed cognitive engine architecture consists of a case-based reasoned (CBR) and a Genetic Algorithm (GA) optimization routine. This paper discusses the overall cognitive architecture, the relationship between the CBR and the GA based on weighted objective functions, and metrics for assessing performance. Methods for case representation, quantifying similarity between cases histories, and techniques for managing case growth rate are presented as well as a proposed test bed SDR platform.

Full textAbstract:
Variable valve timing technologies for internal combustion engines are used to improve power, torque, reduce emissions and increase fuel efficiency. Firstly, the paper presents a new electrohydraulic FVVA system which can control the seating velocity of engine valve flexibly. Secondly, based on the NSGA-II genetic algorithm, outlines multi-objective optimization strategy, the paper designs the parameters of FVVA system to make the system easier to implement. Thirdly, the paper builds the combined FVVA engine simulation model. The combined simulation and experimental are executed to validate the designed FVVA engine. Simulation results show brake power is improved between 1.31% and 4.48% and torque is improved by 1.32% to 4.47%. Brake thermal efficiency and volumetric efficiency also show improvement. Experimental results have good agreement with simulation results. The research results can provide a basis for engine modification design.

Full textAbstract:
Cavitation in pumps is a well-known phenomenon that occurs when local static pressure approaches vapor pressure for the working fluid. The flowing fluid under this condition changes its phase from liquid to gas and form bubbles. These bubbles travel along with flowing fluid and reach a zone with relatively high pressure. As the pressure builds up, the size of the bubble reduces and at some stage bubbles collapse generating very high pressure locally that could damage the metallic blade surfaces. Extensive research activities are going to investigate cavitation phenomenon. At Kirloskar Bothers Ltd, a mixed flow pump was investigated thoroughly for its cavitation performance. The newly introduced Cavitation module in a CFD package, CFX, was used to predict the cavitation phenomenon for this pump. The performance of the pump was predicted first by using single-phase module. The overall performance prediction of the pump matched well with the measured results. The solver was switched over to account for cavitation study using multiphase flow phenomenon. The numerical approach brings out formation of vapor and growth of its volume fraction as the suction pressure is dropped. The paper describes both of these approaches and presents results in the form of impact of cavitation on overall performance of the pump. The vapor bubble formation and its volume fraction growth with reduction in suction pressure are brought out using numerical approach.

"Modeling of Sintered Metal Fiber Diesel Particulate Filter Wall Permeability Based on 3D Digital Structure From CT-Scan." In ASME 2015 Internal Combustion Engine Division Fall Technical Conference. American Society of Mechanical Engineers, 2015. http://dx.doi.org/10.1115/icef2015-1170.
Full textAbstract:
Sintered metal fiber (SMF) diesel particulate filters (DPF) systems efficiently remove particulate matter (PM) emission from diesel engine exhaust with low flow resistance. The permeability of DPF filtration media is the key property determining DPF fuel penalty to the engine. To advance the understanding and optimization of SMF filtration media, a general model to compute SMF media permeability based on 3D digital structure from computed tomography scan (CT-Scan) is developed in this study. An open source computational fluid dynamics (CFD) tool, OpenFOAM, is used to calculate the SMF porous media permeability. The media samples computation domain is approximately 0.9mmx0.9mmx1.8mm (depth) and one hour is needed for each simulation with 8–9 million mesh cells. The study reveals variations of permeability among different SMF media samples. The computed permeability from the 3D simulation has a good agreement with experiment data and achieves a much better accuracy than previous analytical models. In addition, through this study, a significant amount of in-depth information of flow field across the porous media is obtained, which is beneficial to improve the understanding of DPF fibrous media and builds the foundation for more advanced filtration model development.

"An Experimental Investigation of the Exhaust Emissions From Spark-Assisted Homogeneous Charge Compression Ignition in a Single-Cylinder Research Engine." In ASME 2009 Internal Combustion Engine Division Spring Technical Conference. ASMEDC, 2009. http://dx.doi.org/10.1115/ices2009-76083.
Full textAbstract:
The present study investigates the potential impact of spark-assisted (SA) homogeneous charge compression ignition (HCCI) on pollutant exhaust gas emissions from an internal combustion engine. A single-cylinder research engine was used to compare the exhaust emissions of the engine when operated in HCCI, SA-HCCI and conventional spark ignited modes of operation. The study builds on previous results demonstrating the effects of the spark plasma kernel on the ignition process [1, 2]. Specifically, this study investigates the NOx, CO, and HC emissions from an optical engine fueled with indolene in HCCI and SA-HCCI modes at fuel lean conditions. Fuel/air equivalence ratios ranged from φ = 0.3–0.6. Time-averaged emissions were measured using an exhaust gas analyzer. In-cylinder pressure data were also acquired. The results show NOx emissions follow the trends of peak in-cylinder pressure implying that thermal NOx mechanisms dominate both the HCCI and SA-HCCI modes of engine operation. For SA-HCCI, spark timing could be used to change ignition phasing, and consequently change the in-cylinder peak pressure and resulting NOx emissions. Comparing HCCI and SA-HCCI emissions at nominally similar conditions (specifically, comparable indicated mean effective pressures and equivalence ratios) yielded similar NOx emissions. These data show that SA-HCCI may not have a NOx penalty when the spark timing is carefully applied.

Full textAbstract:
Among all critical components in heavy duty diesel engines, cylinder head is generally counted as the most challenging part due to the complex loading conditions. This component experiences both thermal and mechanical stresses. Temperature difference between combustion gases and cooling water induces significant thermal stress in the flameface, while the firing pressure builds up cyclic mechanical stresses superimposed on the former thermal stress. On the other hands, cylinder heads are geometrically complex and generally contain many small fillets and blends. These small geometrical features and complex loading condition cause multiaxial stress state which should be considered during High Cycle Fatigue (HCF) life assessment. In this study, a detailed finite element analysis has been conducted on a heavy duty diesel engine cylinder head, which is followed by HCF life assessment. In order to predict the HCF safety factor, a post-processing routine has been developed using ANSYS Parametric Design Language (APDL) based on a normal stress critical plane approach. This method is shown as a promising approach for multiaxial HCF life assessment of a wide range of engineering metals. Moreover, normal stress critical plane approach is known as a computationally time efficient approach for the huge finite element models. Notch effect has been considered by introducing the relative stress gradient parameter, which is obtained from the best fit of fatigue test data for different notch geometries. Finally, the effect of HCF on Low Cycle Fatigue (LCF) crack growth has been discussed.

This case study engages with the journey of Dhwani Rural Information Systems, a social enterprise that traces its earliest origins back to 2012. Founded by the duo of Sunandan Madan and Swapnil Aggarwal – engineers by training who met while studying for a postgraduate course at the Institute of Rural Management Anand (IRMA) – Dhwani since its inception has been trying to help a range of social sector organizations effectively integrate technology without disrupting the core ways in which these organizations work. Notably, it has been amongst one of the early enterprises in the sector which has taken efforts to understand in-depth the technology-related “pain points” common across organizations, and to bring a degree of standardisation to their solutions. The case builds an appreciation towards the fact that at the core of a successful technology-centric social enterprise, which can offer relevant and affordable digital products and services to the sector, lies building a composite culture that can straddle both the developmental and technological landscapes. Such a culture seeks to combine engineering and consulting skills in equal measure, and seeks to solve problems mindful of the particularities of the developmental sector, while also retaining a service orientation. In particular, the case looks to draw attention to the ideas of hybridity and elasticity that are integral to such a culture and how these have to be sustained against continuous pressures of talent sourcing, compensation, retention, and learning and development. In a short period of time, Dhwani has become a mature set-up with a clear sector-agnostic product and service value proposition to the sector, with a team strength of over 120 people and over 50 projects, and a variety of organizations, including nonprofits, philanthropies, CSR divisions and governments as clients. Therefore, the experiences of the founders and members of the team offer valuable lessons for other like-minded practitioners. At the same time, to researchers in the field of social enterprise the case may provide a more granular view of important aspects of culture-building in emerging social enterprises. The fact that such enterprises have to draw from a talent pool in constant competition with their private sector counterparts imparts added force to the above considerations.
