A task scheduling algorithm for HPC applications using colored stochastic Petri Net models
2017
The increase in demand for High Performance Computing (HPC) scientific applications motivates the efforts to reduce costs of running these applications. The problem to solve is that of dynamical multi-criterial optimal scheduling of an application on a HPC platform with a high number of heterogeneous nodes. The solution proposed by the authors is a HPC hardware-software architecture that includes the infrastructure for two level (node and inter-node level) adaptive load balancing. The article presents the development of an Coloured Petri Net(CPN) for such an architecture. The model was used for the development of a dynamic distributed algorithm for the scheduling problem. The CPN allowed a …
Human capital evaluation in knowledge-based organizations based on big data analytics
2020
Abstract Starting from a Human Capital Analysis Model, this work introduces an original methodology for evaluating the performance of employees. The proposed architecture, particularly well suited to the special needs of knowledge-based organizations, is articulated into a framework able to manage cases where data is missing and an adaptive scoring algorithm takes into account seniority, performance, and performance evolution trends, allowing employee evaluation over longer periods. We developed a flexible software tool that gathers data from organizations in an automatic way – through adapted connectors – and generates abundant results on the measurement and distribution of employees’ perf…
The Co-creation Canvas
2021
Abstract Digital transformation has become an increasingly important topic among enterprises and in research. The adoption of enterprise systems is such an investment, and it usually requires significant change management activities to realize the potential benefits. One important issue is how firms should go about to make investments in appropriate digital technology – and the appropriate changes to organizational processes and business models. This is particularly challenging for small and medium-sized enterprises (SMEs). They generally have very limited resources, and they usually depend on external input and cooperation with other companies. Therefore, a successful strategy for many SME…
Smart ICT Support for Business Networks
2005
Modern companies lean increasingly towards innovating and renewing their business operations in a more value-adding and customer-centric direction. As a prerequisite to this, a number of companies are willing to combine their knowledge and resources, for instance by forming strategic alliances supported by a mixture of open ICT infrastructure and proprietary and interoperable ICT applications. This study examines a network of three focal companies that are seeking cost-efficient expansion of their services. As the potential market for these complex customer services is worldwide, the objective is expected to be met only with the help of ICT. Furthermore, the view among the companies is rela…
Co-creation in networks of SMEs: a conceptual model of the co-creation process
2021
Abstract The ability to adopt new digital technology is a very challenging endeavour, especially for small and medium-sized enterprises (SMEs), who because of resource poverty are dependent on external input and cooperation with other companies. Recent research has indicated that co-creation among SMEs is a promising way to overcome such limitations. However, there has been very limited research on the co-creation process, and we have little understanding about how SMEs would go about to establish and run a co-creation network. We propose a conceptual model based on our review of the literature and our empirical findings from investigating co-creation in four networks. The results expand ou…
Language in globalised interactive business: adaptation vs. standardisation
2017
We investigate language-related choices made in online firms characterised as 'interactive' and having multiple and varying audiences, in both consumer and business marketing environments. Online language choices and their relatedness with firm strategic and tactical behaviour have little received scrutiny. Using survey data, we investigate the role language plays in online firms. We scrutinise whether or not firms significantly adapt to their targeted markets through language and how such adaptive or standardising behaviour relates with firm internationalisation level, and furthermore, if this behaviour relates with how firms interact with their environment. When studying how firms interac…
Agility and system documentation in large-scale enterprise system projects: a knowledge management perspective
2021
Abstract The growth of the agile approach usage comes with a deemphasis on formal documentation (explicit knowledge) and an increased reliance on personal interactions (tacit knowledge) for knowledge transfer. However, the sharing of tacit knowledge poses challenges. The agile approach is prone to knowledge hoarding, as well as knowledge loss from employee turnover and reassignment during periods of significant organizational changes. This study proposes a model that frames documentation and personal interactions as co-agents of system knowledge transfer. We report the preliminary confirmation of crucial antecedents along the dimensions of codification and personalization strategies to supp…
FCA-based knowledge representation and local generalized linear models to address relevance and diversity in diverse social images
2019
Abstract In social image retrieval, the main goal is to offer a relevant but also diverse result set of images to the user. To address relevance and diversity at the same time, we propose a multi-modal procedure. This approach deals with the diversification problem using a two-step procedure based on the application of Formal Concept Analysis (FCA) to organize the text content of the images, followed by a Hierarchical Agglomerative Clustering (HAC) step to find the topics addressed by the images. FCA detects the latent concepts covered by the images in the result set, organizing them according to these concepts. In the second step, clustering is carried out to group together the ones with a…
The Duality of Entropy/Extropy, and Completion of the Kullback Information Complex
2018
The refinement axiom for entropy has been provocative in providing foundations of information theory, recognised as thoughtworthy in the writings of both Shannon and Jaynes. A resolution to their concerns has been provided recently by the discovery that the entropy measure of a probability distribution has a dual measure, a complementary companion designated as &ldquo
Holocene interaction of maritime and continental climate in Central Europe: New speleothem evidence from Central Germany
2019
Central European climate is strongly influenced by North Atlantic (Westerlies) and Siberian High circulation patterns, which govern precipitation and temperature dynamics and induce heterogeneous climatic conditions, with distinct boundaries between climate zones. These climate boundaries are not stationary and shift geographically, depending on long-term atmospheric conditions. So far, little is known about past shifts of these climate boundaries and the local to regional environmental response prior to the instrumental era.\ud \ud High resolution multi-proxy data (stable oxygen and carbon isotope ratios, S/Ca and Sr/Ca) from two Holocene stalagmites from Bleßberg Cave (Thuringia) are used…
