Forest accessibility, Madonie mountains (northern Sicily, Italy): implementing a GIS decision support system

2021

Valorisation and sustainable exploitation of woody biomass from cultivation interventions might be an important opportunity to track alternative development trails for rural communities in natural protected areas. The governance of Mediterranean protected areas is characterized by overlapping, sometimes conflicting institutions, stakeholders and regulations, causing negative impacts on decision-making processes. We present an open source GIS-based decision support system tool for mapping forest accessibility and optimizing woody biomass extraction. Two models were implemented to support forest managers during the decision-making process in designing and managing wood-energy supply chains. T…

The Coaching Maps as a Tool for Developing Reflectivity in Organisations

2018

Przyszłość wymaga od ludzi innego spojrzenia na funkcjonowanie organizacji, wykonywang=ą w nich przez ludzi pracę oraz posiadane przez menedżerów kompetencje. świecie ponowoczesności i postfordyzmu gospodarka i organizacje funkcjonują w odmienny sposób ni? w XX wieku. Tym samym innego rodzaju oczekiwania adresowane są do pracowników. Refleksyjność stała się nie tylko jednym z kluczowych zasobów ludzi i organizacji, lecz także przedmiotem kształcenia. Autorzy tekstu, w oparciu o model auto- etnografii i action-research, ukazują autorskie narzędzie do pracy rozwojowej, skierowane do menedżerów i pracowników m.in. w kontekście kreowania i wyzwalania w nich refleksyjności.

Convergence Analysis of Distributed Set-Valued Information Systems

2016

This paper focuses on the convergence of information in distributed systems of agents communicating over a network. The information on which the convergence is sought is not rep- resented by real numbers, as often in the literature, rather by sets. The dynamics of the evolution of information across the net- work is accordingly described by set-valued iterative maps. While the study of convergence of set-valued iterative maps is highly complex in general, this paper focuses on Boolean maps, which are comprised of arbitrary combinations of unions, intersections, and complements of sets. For these important class of systems, we provide tools to study both global and local convergence. A distr…

Vineyard design supported by GPS application

2021

The innovative technologies of precision agriculture offer nowadays new applications in line with the needs of the wine sector. In hillside viticulture, within the same plot there are areas with different physical and chemical characteristics (lying, pH, active limestone, nutrients, etc.). This variability consequently influences the vigor of the vine which translates into a different production per single plant in terms of both yield and quality of the grapes. The aim of this study was to realize geo-referenced thematic maps by GPS application on a hilly plot covering about 6 hectares to be planted in a hedgerow trained vineyard for the production of quality grapes. The experimental tests …

(Un)exhausted Cartographies. Re-living the visuality, aesthetics and politics in contemporary mapping theories and practices

This thesis is concerned with examining the life and deadliness of the map trope in contemporary Human Geography and the various ways maps and mapping have been re-theorized over the past twenty five years. Arguing that there is presently a feeling of exhaustion and disinterest amongst many human geographers in the use of maps given a shift to postmodern and poststructural approaches that decentre maps and mistrust their supposed objectivity, their representational qualities, and use by institutions to justify certain political actions, it tries to relive the attention in the ubiquity and flourishing of contemporary mapping practices by promoting a re-worked post-representational perspectiv…

Les représentations spatiales de concepts scientifiques : inventaire et diversité

1994

The consultation of twelve journals (French and English language) that deal with science education, for the years 1991 to 1993, allowed us to summarize the use of spatial representations of scientific concepts in didactics research. Two main results were produced from this study : there has not been much work published with spatial representations, and what has been published is very heterogeneous. Analysis of this diversity does not always allow us to understand the authors’ objectives and obliges researchers in didactics to think about the nature and role of spatial representations in the construction of scientific knowledge.

Using affinity perturbations to detect web traffic anomalies

2013

The initial training phase of machine learning algorithms is usually computationally expensive as it involves the processing of huge matrices. Evolving datasets are challenging from this point of view because changing behavior requires updating the training. We propose a method for updating the training profile efficiently and a sliding window algorithm for online processing of the data in smaller fractions. This assumes the data is modeled by a kernel method that includes spectral decomposition. We demonstrate the algorithm with a web server request log where an actual intrusion attack is known to happen. Updating the kernel dynamically using a sliding window technique, prevents the proble…

Distributed spatial prediction for radio environment maps reconstruction in heterogeneous wireless networks

2017

Las previsiones indican que el tráfico de datos móviles se multiplicará por siete en el periodo de 2016 a 2021, creciendo con una tasa agregada anual del 47%. Para satisfacer esta demanda, tanto la industria como la academia se están centrando en las redes de quinta generación o 5G. Las redes 5G se espera que constituyan un entorno complejo e interconectado, que además proporciones múltiples servicios y aplicaciones a un número masivo de usuarios y máquinas. En este concepto se incluye la necesidad de dar soporte o de crear servicios para el paradigma conocido como el Internet de las Cosas (IoT), donde la visión es la de crear un entorno de todo conectado con todo en todo momento, con aplic…

Online Mathematics With Interactive Concept Maps

2008

There has not been a free and easy-to-use utility to handle both authoring and presentation of large graphs online, especially with mathematical content. On one hand, concept map editors are ideal for authoring graphs, but publishing capabilities may be limited. On the other hand, numerous browsing and layout tools exist for publishing content generated elsewhere. We present a transformation tool Xcm2kg that tries to solve the problem by integrating authoring with IHMC CmapTools to publishing based on TouchGraph. GXL is used as an intermediate format to facilitate interoperability with other graph-based applications. The tool is demonstrated with concept maps drawn on an undergraduate mathe…
