Towards Controlling the Acceptance Factors for a Collaborative Platform in Engineering Design

International audienceThis paper might serve as a guide to take step towards a better acceptance of computer-based Knowledge management (KM) tools in institutional setting. At first time, it investigates a set of factors with different origins which are proved to have an effect on usage decision. Secondly, we set a list of candidate factor which are supposed to influence future users of a collaborative KM platform (Dimocode). At the end, we develop a methodology to take into account the selected factors and master their positive or negative impacts. The contents of this paper would be an appropriate framework in the way of Knowledge management systems (KMS) deployment

From manifolds to thoughts

Advances in Machine Learning (ML) models have surpassed our ability to understand the inner “thinking process” that led to their results, leaving us with the same interrogations we ask to understand their biological counterpart, the brain. Here, the geometry of collective neural representations seems to be a crucial characteristic of information processing in both artificial and natural neural networks (NN). However, the dynamical aspect of these neural maps and the cognitive processes that operate on them are still largely unexplored

Back-End Dielectrics Reliability under Unipolar and Bipolar AC-Stress

International audienceThe present paper compares the effects of AC and DC electrical stress on low-kappa SiOCH and high-kappa ZrO2 and Ta2O5 back-end dielectrics. A wide panel of stress conditions has been assessed, mixing DC, unipolar/bipolar and relaxation times. The DC-stress being the reference stress condition, no enhancement of the time-to-breakdown (T-BD) has been found with pure bipolar stress. On the contrary unipolar stress showed a strong improvement of this characteristic. We propose that the lifetime enhancement is due to a charge detrapping mechanism within the dielectric that affects the defect density. Under unipolar-and relax-bipolar-stress the time-to-breakdown has been corrected by the duty cycle in order to consider the effective duration of the stress. In this study no impact of copper has been found on the breakdown behaviour

The Need for Improved Integration between PLM and KM: A PLM Services Provider Point of View

Part 1: Knowledge ManagementInternational audienceWith widespread use of digital tools in industry, an increasing amount of data and knowledge can be edited, shared and made accessible throughout the product lifecycle. As such, new technologies, that provide a formal framework for managing and organizing the intellectual assets of a business, can significantly influence the application of knowledge and the extent to which this knowledge will serve as a source of sustainable differentiation. Similarly, much suggests that the management of knowledge can positively influence and support the links between individual activities in the value stream, hence enabling the product-centered approach, which is fundamental to product lifecycle management (PLM). This paper draws on our experiences as a PLM and Knowledge Management (KM) supplier and highlights industry examples in aeronautics. It explores the potential application of a combined approach that utilizes digital support to encourage the effective use of KM throughout the product lifecycle

An agar dilution method for the determination of the minimum inhibitory concentration of essential oils

Abstract Methods for the measurement of the minimum inhibitory concentration (MIC) of antibacterial agents have been developed for water-soluble substances and require adaptation for use with water-insoluble essential oils. This paper reports a standardized agar dilution MIC method, using 0.5% v/v Tween 20 as a dispersant, which provides a reliable and reproducible technique. The method was tested using two Melaleuca alternifolia oil samples with two different levels of terpinen-4-ol (37% and 45% v/v). The MIC values of the tea tree oil samples against a wide selection of bacteria, moulds and yeast are reported

The Methodological Challenges Related to Assess the Outcomes of Knowledge Management Initiatives: The Case of Communities of Practice

Part 8: Knowledge Management and Information SharingInternational audienceIn any organizational project where the use of limited resources represents a challenge, it’s necessary to assess the outcomes generated. The methodological approach on how to assess outcomes reveals many questions, namely: What is the best way to do so? What dimensions to assess? From what criteria? How to estimate them? In the case of communities of practice (CoP), these questions become accurate. Indeed, in the case of Communities of Practice, the participants represent the cornerstone of the project because there are the ones who generate knowledge. So to assess outcomes generated by CoP within an organization, it’s necessary to identify an adapted methodological frame which will allow to take into account the critical aspects of the CoP and the user perspective. Our proposal aims to present a hybrid path (qualitative-quantitative) in order to minimize the limits and uplift advantages related to both approaches. The addition of these two approaches must generate a more stronger one and a better reliability of concept. For that purpose, the structure of the article concerns the following aspects: the context of knowledge management initiatives and particularly communities of practice; notions of assessment and outcomes; the current methodologies used to assess the outcomes of the CoP as well as their limits; the criteria to be respected for the choice as a strong methodology; the choice of a new approach (qualitative-quantitative) and its future application in the CoP
