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 …
On Applications of Wireless Sensor Networks
2009
Wireless Sensor Networks (WSN) are ad-hoc networks in which small independent sensor nodes have limited energy, computational resources and wireless communication capabilities. Recently, both academia and industry have shown great interest in the area of Wireless Sensor Networks. This paper focuses on the practical applications in commerce and feasible future employment of WSNs. Continued advances of wireless communication technologies have led to the following fields of applications: habitat and environmental monitoring, security of buildings and property, oil and gas installations, mines and tunnels, emergency medical care, military applications. In the near future WSNs will certainly ent…
A knowledge-based exploratory framework to study quality of Italian mobile telecommunication services
2017
A novel two-step knowledge-based exploratory framework is proposed in this paper for studying quality of Italian Mobile Telecommunication Services (MTSs). Particularly, the Delphi technique is initially considered to finalize an overall quality structure of MTSs features, indicators and drivers, herein described on the basis of a comprehensive review of the fundamental references for the field, and also to select the key elements with reference to the Italian context. At the second step, selected key elements are prioritized via the Analytic Hierarchical Process (AHP) method according to viewpoints of the fundamental stakeholders for the sector. Furthermore, possible uncertainty and ambigui…
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…
Integrating business start-up indicators in the flexicurity concept to cover the alternative forms of employment
2016
The flexicurity concept created in the Netherlands and Denmark in the early 1990s has become the main stepping-stone in improving the performance of labour markets across the European Union Member States. The European Commission has therefore taken a leading role on broader flexicurity concept development and creation of the data analysis methodology. However, the analysis proposed by the European Commission Joint Research Centre on flexicurity indicators in 2010 only partly includes business start-ups as a flexible form of employment. This research starts the discussion on whether additional indicators should be integrated in the flexicurity analysis, because of the rising need for employm…
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…
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
