Backsourcing is the process where a client firm brings previously outsourced services from a supplier back in-house. Traditionally, the existing literature on backsourcing has focused on how firms reach the decision to bring back previously outsourced services. In this paper, we move beyond focusing on IT backsourcing decision to explore the process of backsourcing from a knowledge perspective. The predominant view in the relevant literature argues that the re-acquisition of knowledge by a client firm during backsourcing takes place similarly to knowledge acquisition by a supplier in a typical outsourcing process. In this paper, we argue that knowledge re-integration in backsourcing occurs differently from outsourcing projects mainly because of the existence of knowledge asymmetries between the client and the supplier. By examining seven backsourcing events, we reveal that knowledge transfer and re-integration in backsourcing emerges as a coordinative activity, complementing knowledge transfer mechanisms reported in the IS outsourcing literature.

To capture the genomic profiles for histone modification, chromatin immunoprecipitation (ChIP) is combined with next generation sequencing, which is called ChIP-seq. However, enriched regions generated from the ChIP-seq data are only evaluated on the limited knowledge acquired from manually examining the relevant biological literature. This paper proposes a novel framework, which integrates multiple knowledge sources such as biological literature, Gene Ontology, and microarray data. In order to precisely analyze ChIP-seq data for histone modification, knowledge integration is based on a unified probabilistic model. The model is employed to re-rank the enriched regions generated from peak finding algorithms. Through filtering the reranked enriched regions using some predefined threshold, more reliable and precise results could be generated. The combination of the multiple knowledge sources with the peaking finding algorithm produces a new paradigm for ChIP-seq data analysis.

The article analyses the possibilities and advantages of geography integration trying to develop the educational process in a secondary school. Every teaching strategy style must always be carefully selected, paying attention to students‘ age experience and abilities. Re-cently, abilities‘ use in practice is more emphasized than theoretical knowledge. Geography is the most integrated subject at school. The majority of other subjects‘ knowledge is needed in teaching how to do geography projects and research works. Therefore, subject integration is very important. It allows to select the most important various subjects knowledge and get the most optimal result. Key words: teaching/learning strategy, learning style, research and project activity, subject integration, subject and common competence.

Full textAbstract:
Biological pathway data integration has become a topic of interest in the past years. This interest originates essentially from the continuously increasing size of existing prior knowledge as well as from the many challenges scientists face when studying biological pathways. Multipath is a framework that aims at helping re-trace the use of specific pathway knowledge in specific publications, and easing the data integration of multiple pathway types and further influencing knowledge sources. Multipath thus helps scientists to increase the reproducibility of their code and analysis by allowing the integration of numerous data sources and documentation of their integration steps while doing so. In this paper, we present the package Multipath, and we describe how it can be used for data integration and tracking pathway modifications. We present a multilayer model built from the Wnt Pathway as a demonstration.

Purpose – Knowledge workers (KWs) in information technology (IT) sector have become one of the key drivers for strategic competitiveness as they contribute toward an organization’s performance. In this context, the role of knowledge workers, who work on deputation to client side, is even more critical as they contribute directly to the revenue inflows. The purpose of this paper is to explore their role efficacy (RE) and organizational role stress dimensions, which have been affecting their performance and organization effectiveness. The study further explored the relationship between RE and role stress dimensions. Two distinct samples were identified, one where Indian KWs working in Indian company and Indian KWs working in foreign firm, where they have been discharging client facing technical roles. Design/methodology/approach – A primary study has been conducted choosing questionnaire survey and telephonic interviews. A questionnaire was designed in such a manner so that the authors can extract the required information from the respondents about various dimensions of RE. This instrument was used to test the conceptual model of RE. Overall 50+ responses were obtained from IT companies in each of the two selected categories. Findings – The results have shown that role expectation conflict and role isolation are the two major dimensions contributing to role stress for the selected sample, while centrality and integration have contributed to overall role efficacy for both the categories. Human resource interventions were suggested to enhance their RE and reduce their role stress. Originality/value – This study made an attempt to investigate the relationship between RE and role stress dimensions of the KWs which has not been attempted in any previous published literature.

<p><em>One of the prominent factor leading to the continuing decline of the Muslim Ummah is rivalry between scientific mind and traditional mind-set. The modern Muslim intellectuals are fascinated by scientific developments in the West and discouraged by the inability of Ummah. The process of re-emergence as developed community is imbedded in re-Islamization of scientific knowledge. The rise of Muslim Ummah is tied with integration of Shari’ah based knowledge and scientific knowledge. The focus of the Muslim intellectual pursuits must once again gravitate towards these two fountains of true knowledge. To achieve this goal, Said Nursi a versatile personality, a true representative of Islam came with all-inclusive ideas for integration of both the knowledge’s. He advocates the Qur’anic Scientism and discussed faith based research (iman tahqiqi) relying on positive action (jihad Manaavi) in Risal-i Nur. In this paper an Attempt has been made to acme the Qur’anic Scientism in Risal-i- Nur, to prove Qur’anic Scientism highly applicable while as Said Nursi as admirably a true representative of Qur’anic Message in the modern era.</em></p>

A qualitative case study was conducted at six purposively sampled universities; out of a population of approximately23 universities. This sampling strategy was based on selecting some universities that became Universities ofTechnology during the process of merging Higher Education Institutions (HEIs) while other universities kept theiridentity; currently being referred to as Traditional Universities. In-depth interviews and analysis of curriculumdocuments were used as sources of data acquisition to address the aim and questions explored by this study explored;necessitated by the need to implement Minimum Requirements for Teaching Education Qualification (MRTEQ)policy guidelines. The sampled universities’ identities were concealed and pseudonyms were assigned to participantsfor ethical reasons. Qualitative methods were applied for data analysis. Findings revealed that for some institutions’integration of sub-disciples of science curriculum led to contestations and debates resulting from differentphilosophical perceptions held by subject specialists in the curriculum design process. Knowledge integrationcontinues to be a contested field in universities that typifies resistance to change. Some participants demonstrated apositive disposition towards knowledge integration models which they used in curriculum development. This studyconcludes that a collaborative and collegial deliberation among science education lecturers and experts in variousknowledge domains could be a way to find common ground on issues highlighted in this study. Re-thinking andre-conceptualising knowledge organisation for science academic knowledge are appropriate to the needs of schoolcurriculum and benefit science teachers with knowledge and competences for knowledge impartation, skills andvalues in the subject.

Full textAbstract:
System dynamics modelling has been used for around 40 years to address complex, systemic, dynamic problems, those often described as wicked. But, system dynamics modelling is not an exact science and arguments about the most suitable techniques to use in which circumstances, continues. The nature of these wicked problems is investigated through a series of case studies where poor situational awareness among stakeholders was identified. This was found to be an underlying cause for management failure, suggesting need for better ways of recognising and managing wicked problem situations. Human cognition is considered both as a limitation and enabler to decision-making in wicked problem environments. Naturalistic and deliberate decision-making are reviewed. The thesis identifies the need for integration of qualitative and quantitative techniques. Case study results and a review of the literature led to identification of a set of principles of method to be applied in an integrated framework, the aim being to develop an improved way of addressing wicked problems. These principles were applied to a series of cases in an action research setting. However, organisational and political barriers were encountered. This limited the exploitation and investigation of cases to varying degrees. In response to a need identified in the literature review and the case studies, a tool is designed to facilitate analysis of multi-factorial, non-linear causality. This unique tool and its use to assist in problem conceptualisation, and as an aid to testing alternate strategies, are demonstrated. Further investigation is needed in relation to the veracity of combining causal influences using this tool and system dynamics, broadly. System dynamics modelling was found to have utility needed to support analysis of wicked problems. However, failure in a particular modelling project occurred when it was found necessary to rely on human judgement in estimating values to be input into the models. This was found to be problematic and unacceptably risky for sponsors of the modelling effort. Finally, this work has also identified that further study is required into: the use of human judgement in decision-making and the validity of system dynamics models that rely on the quantification of human judgement.

Full textAbstract:
Due to physical, cognitive and emotional impairments, many individuals are unemployed or under-employed following a traumatic brain injury. The research evidence links the rigour of a vocational evaluation to future employment outcomes. Despite this link, no specific guidelines exist for vocational evaluations. Using the research evidence and a diverse panel of clinical and academic experts, the primary objective of this doctoral research was to develop an inter-professional clinical practice guideline for vocational evaluation following traumatic brain injury. The objective of the guideline is to make explicit the processes and factors relevant to vocational evaluation, to assist evaluators (i.e. clients, health and vocational professionals, and employers) in collaboratively determining clients’ work abilities and developing recommendations for work entry, re-entry or vocational planning. The steps outlined in the Canadian Medical Association's Handbook on Clinical Practice Guidelines were utilized to develop the guideline and include the following: 1) identifying the guideline’s objective/questions; 2) performing a systematic literature review; 3) gathering a panel; 4) developing recommendations; 4) guideline writing; 5) pilot testing. The resulting guideline includes 17 key recommendations within the following seven domains: 1) evaluation purpose and rationale; 2) initial intake process; 3) assessment of the personal domain; 4) assessment of the environment; 5) assessment of occupational/job requirements; 6) analysis and synthesis of assessment results; and 7) development of evaluation recommendations. Results from an exploratory study of the guideline’s implementation by occupational therapists in their daily practices revealed that clinicians used the guideline to identify practice gaps, systematize their evaluation processes, enhance inter-professional and inter-stakeholder communication, and re-conceptualize their vocational evaluations across disability groups. Statistically significant improvements were also noted in clients’ participation scores on the Mayo-Portland Adaptability Inventory–4 following guideline use. This guideline may be applicable to individuals with TBI, clinicians, health and vocational professionals, employers, professional organizations, administrators, policy makers and insurers.

As founder and director of the Youth Media Literacy Project and a self-titled Imagitator (one who agitates imagination), I have spent over 10 years teaching media literacy in various high schools, universities, and community centres across North America. This study will focus on my own personal practical knowledge (Connelly & Clandinin, 1982) as a culture jammer, educator and cancer survivor to illustrate my original vision of a ‘holistic media literacy pedagogy’. This research reflects on the emergence and impact of holistic media literacy in my personal and professional life and also draws from relevant interdisciplinary literature to challenge and synthesize current insights and theories of media literacy, holistic education and culture jamming.

Full textAbstract:
This article assesses the impact of innovation on Roman society. It starts from a critical engagement with past debate about technological progress, which over the past decades has been too strongly focused on economic growth, and a re-appreciation of the literary evidence for innovation, which points to a culture in which technological knowledge and invention were thought to matter. Then, it highlights two areas where the uptake of technology had a direct impact on everyday life: material culture, where the emergence of glass-blowing, a proliferation of metal-working, and innovation in pottery-production changed the nature and amount of artefacts by which people surrounded themselves, and construction, where building techniques using opus caementicium, arches and standardized building materials revolutionized urban and rural landscapes. A concluding discussion highlights the role of integration of the Mediterranean under Roman rule in making innovation possible, and the role of consumer demand in bringing it about.

AbstractCreation and re-usability of language resources in accordance with Linked Data principles is a valuable asset in the modern data world. We describe the contributions made to extend the Linguistic Linked Open Data (LLOD) stack with a new resource, Coreon MKS, bringing together concept-oriented, language-agnostic terminology management and graph-based knowledge organisation. We dwell on our approach to mirroring of Coreon’s original data structure to RDF and supplying it with a SPARQL endpoint. We integrate MKS into the existing ELG infrastructure, using it as a platform for making the published MKS discoverable and retrievable via a industry-standard interface. While we apply this approach to LLOD-ify Coreon MKS, it can also provide relevant input for standardisation bodies and interoperability communities, acting as a blueprint for similar integration activities.

AbstractThis chapter surveys three educational policies that contend with cultural difference: cultural sensitivity, multiculturalism, and interculturality. Liberal paradigms such as these operate on the premise of good faith, in which sincere engagement with cultural differences promotes integration into the wider social order and aids in ameliorating racism and ethnic conflict. Critics, however, challenge policies of discursive inclusion for failing to address structural and systemic inequality, which requires more substantive interventions. The origins of educational inequality can be traced to class relations and coloniality, and therefore it is incumbent to question inherited myths and official histories as well as eurocentric concepts, categories, and methods. Decolonizing approaches provide alternative perspectives on culture that, in challenging existing governmental and social arrangements, seek to re-envision educational systems starting at the foundational level of knowledge construction. This contemporary approach is preceded by a long history of Muslim educationists seeking to promote religiosity through a universal outlook based in equality, expressed in “South-South” linkages predating concepts of the third world and global South. Examining education and culture over the longue durée provides a useful context for contemporary debates that problematize eurocentrism and disparities in educational outcomes.

Full textAbstract:
AbstractA wealth of public data repositories is available to drive genomics and clinical research. However, there is no agreement among the various data formats and models; in the common practice, data sources are accessed one by one, learning their specific descriptions with tedious efforts. In this context, the integration of genomic data and of their describing metadata becomes—at the same time—an important, difficult, and well-recognized challenge. In this chapter, after overviewing the most important human genomic data players, we propose a conceptual model of metadata and an extended architecture for integrating datasets, retrieved from a variety of data sources, based upon a structured transformation process; we then describe a user-friendly search system providing access to the resulting consolidated repository, enriched by a multi-ontology knowledge base. Inspired by our work on genomic data integration, during the COVID-19 pandemic outbreak we successfully re-applied the previously proposed model-build-search paradigm, building on the analogies among the human and viral genomics domains. The availability of conceptual models, related databases, and search systems for both humans and viruses will provide important opportunities for research, especially if virus data will be connected to its host, provider of genomic and phenotype information.

This chapter examines from a Knowledge Integration (KI) perspective the innovation potential that resides in KI for the generation of Information System (IS) based on organizational innovation. The chapter does this by examining methodologically the process of Requirements Engineering (RE) as a research topic and uses for this purpose a mixed-method approach including literature review, participant observation, and recourse to secondary research. The chapter first outlines the emergence of KI as research topic in its own right before the emergence of IS as innovation in organizations is described. The chapter then examines the innovation inhibitors to KI as proxy for innovation generation. It argues in the conclusion that taking RE for IS premises and research methods employed in relation to research into KI might be guided by rationalistic efficiency-driven conceptions, while KI as research agenda seems to be premised on a notion of effectiveness.

The chapter investigates two ideal types of knowledge about and for social innovations combating poverty: A model of linear change based on standardized knowledge and a context-sensitive model based on tacit knowledge for transformative alternatives. Case study analysis focussed on the field of homelessness and re-use. Six housing first initiatives in six European cities and two large networks of work integration social enterprises in UK and Flanders were studied to disentangle the dualist model by exploring how and why practitioners use different types of knowledge to pursue their respective mission. While codification and standardisation pushes for standardized knowledge, contextual knowledge is important for successful implementation. In all cases, the respective governance of producing and disseminating knowledge was decisive for effective agency. Knowledge alliances based on multi-level collaborations between stakeholders with different perspectives and forms of expertise were identified as promising forms of producing and disseminating knowledge to upscale and to diffuse socially innovative initiatives and approaches.

This chapter explores the influence of social media on the (re)formation of social memory and the production of alternative historical knowledge in Chinese society. It investigates several contested debates on Weibo over historical events and figures in the Mao era, arguing that social media embraces a wide variety of diverse individuals as subjects who contribute to various mnemonic practices, facilitates the crowdsourcing and aggregation of alternative narratives of the past as counter-hegemonic discourse, and cultivates the production of historical knowledge as an easily retrievable and re-activatable process. The chapter concludes that the integration of fragmented, individual memories into historical knowledge and the facilitation of diversified mnemonic practices on Weibo re-construct the maintenance and production of historical knowledge in the long run in contemporary China.

Object detection in images is a crucial task in computer vision, with important applications ranging from security surveillance to autonomous vehicles. Existing state-of-the-art algorithms, including deep neural networks, only focus on utilizing features within an image itself, largely neglecting the vast amount of background knowledge about the real world. In this paper, we propose a novel framework of knowledge-aware object detection, which enables the integration of external knowledge such as knowledge graphs into any object detection algorithm. The framework employs the notion of semantic consistency to quantify and generalize knowledge, which improves object detection through a re-optimization process to achieve better consistency with background knowledge. Finally, empirical evaluation on two benchmark datasets show that our approach can significantly increase recall by up to 6.3 points without compromising mean average precision, when compared to the state-of-the-art baseline.

Full textAbstract:
Semantic knowledge representation, management, sharing, access, and re-use approaches can support collaborative production planning in a flexible and efficient as well as an effective way. Therefore, semantic-technology based representations of Collaborative Production Process Planning (CAPP) knowledge integrated into a machine readable process formalization is a key enabling factor for sharing such knowledge in cloud-based semantic-enabled knowledge repositories supporting CAPP scenarios as required in the CAPP4SMES project [1]. Beyond that, Small and Medium Enterprises (SMEs) as represented in CAPP4SMES request for a standardized CAPP-oriented product-knowledge- and production-feature representation that can be achieved by applying function-block based knowledge representation models. Semantic Web- and at the same time Cloud-based technologies, tool suites and application solutions which are based on process-oriented semantic knowledge representation methodologies such as Process-oriented Knowledge-based Innovation Management (German: Wissens-basiertes Prozesess-orientiertes Innovationsmanagement, WPIM) [2] can satisfy these needs, supporting the semantic integration, management, access and re-use in a machine readable and integrated representation of distributed CAPP knowledge that is shared within a cloud-based centralized semantic-enabled knowledge repository. Furthermore semantic knowledge representation and querying add value to knowledge-based and computer-aided re-use of such knowledge within CAPP activities and, finally, pave the way towards further automating planning, simulation and optimization support in a semantic web for CAPP.

Full textAbstract:
The proliferation of commercial computerized systems to improve cognitive functions has helped many people, yet several key issues remain open. The current research focuses on the effect of feedback given to trainees in a computerized training system for visual attention. The visual attention skill was trained specifically to control temporal integration: a process in which a series of stimuli with a short break between them is combined together into one stimulus. Two training groups were compared: one with complete feedback during the training (Feedback group) and one without (No Feedback group), with 15 trainees in each group. The results demonstrated that the Feedback group’s performance was significantly poorer compared to the No Feedback group as assessed by the number of errors in new sets (measured during training). The deterioration observed in performance during training is not a common phenomenon. We explain these results by the theory of overconfidence. Based on the research results, we assert that giving feedback during cognitive computerized training can lead to undesirable consequences also in training, and should be re-considered.

Full textAbstract:
Today, in the era of modern Intelligent Production Environments (IPE) and Industry 4.0, the manufacturing of a product takes place in various partial steps and these mostly in different locations, potentially distributed all over the world. The producing companies must assert in the global market and always find new ways to cut costs by saving tax, changing to the best providers, and by using the most efficient and fastest production processes. Furthermore, they must be inevitably based on a cloud-based repository and distributed architectures to make data and information accessible everywhere as well as development processes and knowledge available for a worldwide cooperation. A so called Collaborative Adaptive (Production) Process Planning (CAPP) can be supported by semantic approaches for knowledge representation and management as well as knowledge sharing, access, and re-use in a flexible and efficient way. In this way, to support CAPP scenarios, semantic representations of such knowledge integrated into a machine-readable process formalization is a key enabling factor for sharing in cloud-based knowledge repositories. This is especially required for, e.g., Small and Medium Enterprises (SMEs). When SMEs work together on a production planning for a joint product, they exchange component production and manufacturing change information between different planning subsystems. These exchanges are mostly based on the already well-established Standard for the Exchange of Product model data (STEP), not least to obtain a computer-interpretable representation. Moreover, so-called Function Block (FB) Domain Models could support these planning process. FBs serve as a high-level planning-process knowledge-resource template and to the representation of knowledge. Furthermore, methodologies are required, which based on process-oriented semantic knowledge-representation, such as Process-oriented Knowledge-based Innovation Management (German: Wissens-basiertes Prozess-orientiertes Innovations Management, WPIM). WPIM is already a web- and cloud-based tool suites and can represent such planning processes and their knowledge resources and can therefore be used to support the integration and the management of distributed CAPP knowledge in Manufacturing Change Management (MCM), as well as its access and re-use. That is also valid for Assembly-, Logistics- and Layout Planning (ALLP). On the one hand, a collaborative planning in a machine-readable and integrated representation will be possible as well as an optimization for mass production. On the other hand, within a cloud-based semantic knowledge repository, that knowledge can be shared with all partners and contributors. To combine all these functionalities, in 2016 we have already introduced a method, called Knowledge-based Production Planning (KPP). We outlined the theoretical advantages of integrating CAPP with Collaborative Manufacturing Change Management (CMCM) in the last year at MSEC16. In this Paper, we will demonstrate our first implementations of the KPP application with an integrated visual direct manipulative process editor as well as a first prototype of our mediator architecture with a semantic integration including a query library based on the KPP ontology.

The manufacturing of a product takes place in several partial steps and these mostly in different locations to save tax or to use the best providers. Therefore, in the era of Internet of Things (IoT) and modern Intelligent Production Environments (IPE) are going to be inevitably based on a cloud-based repository and distributed architecture to make data and information accessible everywhere as well as development processes and knowledge available for worldwide cooperation. Semantic approaches for knowledge representation and management as well as knowledge sharing, access, and re-use can support Collaborative Adaptive Production Process Planning (CAPP) in a flexible, efficient, and effective way. Thus, semantic representations of such CAPP knowledge integrated into a machine readable process formalization is a key enabling factor for sharing such knowledge in cloud-based knowledge repositories supporting CAPP scenarios as required for e.g., Small and Medium Enterprises (SMEs). When such contributors work together on a product component production planning, they exchange component production and manufacturing change information between different planning subsystems which require, e.g., a standardized product-feature- and production-machine feature representation. These data exchanges are mostly based on applying the already established Standard for the Exchange of Product model data (STEP) for the computer-interpretable representation and exchange of product manufacturing information. Furthermore, the planning process can be supported by so-called Function Block (FB) based knowledge representation models, serving as a high-level planning-process knowledge-resource template. Web-based and at the same time Cloud-based tool suites, which are based on process-oriented semantic knowledge-representation methodologies, such as Process-oriented Knowledge-based Innovation Management (German: Wissens-basiertes Prozess-orientiertes Innovations Management, WPIM) can satisfy the needs of representing such planning processes and their knowledge resources. In this way, WPIM can be used to support the integration and management of distributed CAPP knowledge, as well as its access and re-use in Manufacturing Change Management (MCM) including Assembly-, Logistics and Layout Planning (ALLP). Therefore, also a collaborative planning and optimization for mass production in a machine readable and integrated representation is possible. On the other hand, that knowledge can be shared within a cloud-based semantic knowledge repository. To integrate all these functionalities, this paper introduces a new method, called Knowledge-based Production Planning (KPP) and outlines the advantages of integrating CAPP with Collaborative Manufacturing Change Management (CMCM). In this way, an enabling basis for achieving ALLP interoperability in Distributed Collaborative Manufacturing and Logistics will be demonstrated.

Full textAbstract:
This paper reports the results of an experimental and analytical study of Reynolds number (Re) effect on Low Pressure Turbine (LPT) performance. LPTs suffer both a loss in efficiency and flow capacity at altitude due to thicker boundary layers and higher viscous losses. Boundary layer separation can occur in highly loaded and/or high lift designs. The magnitude of the effect is stronger for smaller engines being designed for regional jets which may have cruising altitudes above 50K feet. There is a general lack of knowledge about performance degradation in commercial LPTs under these conditions. A test program was undertaken in a low pressure 3 stage axial turbine to quantify the effect of low Re on efficiency and flow lapse rate. Rig inlet pressures were varied from 0.27E+5 N/m2 (4 psia) to 4.40E+5 N/m2 (65 psia) to achieve over a 15 fold variation in Re. The chord based average Re varied from 30000 to 500000. Efficiency and flow function lapse of over 5% was measured. The fall off was non-linear with a rapid loss occurring at Re below 100000. 3D CFD analysis was conducted in parallel to predict overall performance but also understand loss details within the blade rows. Measured inlet profiles of total pressure, temperature and air angle, and exit static pressure were used as boundary conditions. Leakages and purge flows were modeled as source terms. A turbulence transition model and wall integration grids was used. The CFD results corroborate the test findings on the overall efficiency and flow capacity lapse rate. Analysis of blade row performance at high and low Re shows a sharp increase in profile loss at low Re.

Abstract Today’s engineering applications suffer from a severe integration problem. Engineering, i.e. the entire process, consists of a myriad of individual, often complex tasks. Most computer tools support particular tasks in engineering, but the output of one tool is different from the others’. Thus, the user must re-enter the relevant information in the format required by each tool. To achieve a collaborative engineering environment, engineers need some means for relating the information produced by existing software tools. In this paper, a new framework to handle the time-cost trade-off problem in project network is presented. The framework integrates the capabilities of two commercial software, Microsoft Excel™ (spreadsheet), and Microsoft Project™ (project management), with a state-of-the-art knowledge-base called InnerCircle2000™, to solve the mentioned problem interactively.

Recently, computational design aiding tools resources are undertaken in modern companies, enhancing high quality product definition development. However, accurate digital product descriptions are attained through multiple software applications, each one seeking to solve focused needs. Regardless significant advances, there still remains a substantial computational deficiency in how these systems interact with each other between the several PLC stages. Plural issues with different origin and nature contribute to such state, increasing the research community interest to contribute with solution that minimizes the problem. In particular, one main issue refers to product and process knowledge exchange along PLC stages. According to this scenario, and with market pressure to increase profits and reduce redundancies, an efficient coordination and management of all the activities taking place along the Production Process must be performed. Hence, promising technologies of Product Lifecycle Management are considered strategic to manage capture of product knowledge along its life, from initial conception to retirement. This paper proposes the use of an ontology to be used in a knowledge-based system, giving support to a comprehensive product model to improve integration and data exchange capabilities trough entire PLC. The capture, handle and re-use of knowledge from multiple disciplines during PLC (e.g. design, manufacture or maintenance), extending capabilities of existent product and process models is the promising main benefit of ontologies development.

Full textAbstract:
Abstract Reverse Engineering (RE) may help tolerance inspection during production by digitalization of analyzed components and their comparison with design requirements. RE techniques are already applied for geometrical and tolerance shape control. Plastic injection molding is one of the fields where it may be applied, in particular for die set-up of multi-cavities, since no severe accuracy is required for the acquisition system. In this field, RE techniques integrated with Computer-Aided tools for tolerancing and inspection may contribute to the so-called “Smart Manufacturing”. Their integration with PLM and suppliers’ incoming components may set the information necessary to evaluate each component and die. Intensive application of shape digitalization has to front several issues: accuracy of data acquisition hardware and software; automation of experimental and post-processing steps; update of industrial protocol and workers knowledge among others. Concerning post-processing automation, many advantages arise from computer vision, considering that it is based on the same concepts developed in a RE post-processing (detection, segmentation and classification). Recently, deep learning has been applied to classify point clouds, considering object and/or feature recognition. This can be made in two ways: with a 3D voxel grid, increasing regularity, before feeding data to a deep net architecture; or acting directly on point cloud. Literature data demonstrate high accuracy according to net training quality. In this paper, a preliminary study about CNN for 3D points segmentation is provided. Their characteristics have been compared to an automatic approach that has been already implemented by the authors in the past. VoxNet and PointNet architectures have been compared according to the specific task of feature recognition for tolerance inspection and some investigations on test cases are discussed to understand their performance.

Full textAbstract:
Abstract The development of feeding, presentation and fixturing systems are essential in achieving the integration of design and manufacture. A bibliography of over 150 items serves as the basis of this survey of trends in the development of these systems for assembly. Recent technical literature, indicative of academic research and available commercial hardware systems are reviewed. While the emphasis of this paper is on presenting primarily mechanical solutions to the part feeding, presentation and fixturing problem, many papers which focus on AI, vision and knowledge-based systems are also included in the bibliography. In reviewing this literature, it is found that while many solutions have been presented, more work is needed toward fundamental understanding of the mechanics of feeding, presenting and fixturing, so that analysis and modeling can replace some of the re-design steps. This will aid in reducing the lead time by allowing systems to be designed from CAD data, rather than having to wait for prototype parts.

Gur, Amit, Edward Buckler, Joseph Burger, Yaakov Tadmor, and Iftach Klapp. Characterization of genetic variation and yield heterosis in Cucumis melo. United States Department of Agriculture, January 2016. http://dx.doi.org/10.32747/2016.7600047.bard.
Full textAbstract:
Project objectives: 1) Characterization of variation for yield heterosis in melon using Half-Diallele (HDA) design. 2) Development and implementation of image-based yield phenotyping in melon. 3) Characterization of genetic, epigenetic and transcriptional variation across 25 founder lines and selected hybrids. The epigentic part of this objective was modified during the course of the project: instead of characterization of chromatin structure in a single melon line through genome-wide mapping of nucleosomes using MNase-seq approach, we took advantage of rapid advancements in single-molecule sequencing and shifted the focus to Nanoporelong-read sequencing of all 25 founder lines. This analysis provides invaluable information on genome-wide structural variation across our diversity 4) Integrated analyses and development of prediction models Agricultural heterosis relates to hybrids that outperform their inbred parents for yield. First generation (F1) hybrids are produced in many crop species and it is estimated that heterosis increases yield by 15-30% globally. Melon (Cucumismelo) is an economically important species of The Cucurbitaceae family and is among the most important fleshy fruits for fresh consumption Worldwide. The major goal of this project was to explore the patterns and magnitude of yield heterosis in melon and link it to whole genome sequence variation. A core subset of 25 diverse lines was selected from the Newe-Yaar melon diversity panel for whole-genome re-sequencing (WGS) and test-crosses, to produce structured half-diallele design of 300 F1 hybrids (MelHDA25). Yield variation was measured in replicated yield trials at the whole-plant and at the rootstock levels (through a common-scion grafted experiments), across the F1s and parental lines. As part of this project we also developed an algorithmic pipeline for detection and yield estimation of melons from aerial-images, towards future implementation of such high throughput, cost-effective method for remote yield evaluation in open-field melons. We found extensive, highly heritable root-derived yield variation across the diallele population that was characterized by prominent best-parent heterosis (BPH), where hybrids rootstocks outperformed their parents by 38% and 56 % under optimal irrigation and drought- stress, respectively. Through integration of the genotypic data (~4,000,000 SNPs) and yield analyses we show that root-derived hybrids yield is independent of parental genetic distance. However, we mapped novel root-derived yield QTLs through genome-wide association (GWA) analysis and a multi-QTLs model explained more than 45% of the hybrids yield variation, providing a potential route for marker-assisted hybrid rootstock breeding. Four selected hybrid rootstocks are further studied under multiple scion varieties and their validated positive effect on yield performance is now leading to ongoing evaluation of their commercial potential. On the genomic level, this project resulted in 3 layers of data: 1) whole-genome short-read Illumina sequencing (30X) of the 25 founder lines provided us with 25 genome alignments and high-density melon HapMap that is already shown to be an effective resource for QTL annotation and candidate gene analysis in melon. 2) fast advancements in long-read single-molecule sequencing allowed us to shift focus towards this technology and generate ~50X Nanoporesequencing of the 25 founders which in combination with the short-read data now enable de novo assembly of the 25 genomes that will soon lead to construction of the first melon pan-genome. 3) Transcriptomic (3' RNA-Seq) analysis of several selected hybrids and their parents provide preliminary information on differentially expressed genes that can be further used to explain the root-derived yield variation. Taken together, this project expanded our view on yield heterosis in melon with novel specific insights on root-derived yield heterosis. To our knowledge, thus far this is the largest systematic genetic analysis of rootstock effects on yield heterosis in cucurbits or any other crop plant, and our results are now translated into potential breeding applications. The genomic resources that were developed as part of this project are putting melon in the forefront of genomic research and will continue to be useful tool for the cucurbits community in years to come.
