On modified α-ϕ-fuzzy contractive mappings and an application to integral equations
2016
Abstract We introduce the notion of a modified α-ϕ-fuzzy contractive mapping and prove some results in fuzzy metric spaces for such kind of mappings. The theorems presented provide a generalization of some interesting results in the literature. Two examples and an application to integral equations are given to illustrate the usability of our theory.
Towards Practical Cybersecurity Mapping of STRIDE and CWE — a Multi-perspective Approach
2021
Software vulnerabilities are identified during their whole life-cycle; some vulnerabilities may be caused by flaws on the design while other appear due to advances on the technologies around the systems. Frameworks such as OWASP are well- known and are used for testing a systems security before or after implementation, and such testing is carried out against the existing system. Threat modeling however focuses on the early stages of the system design when it is feasible and easy to fix security-related flaws and prevent possible damage caused by them. For example, STRIDE is one very popular threat modeling framework. A STRIDE threat modelling specialist deals with abstract categorizations o…
PROPOSAL FOR A LANDSCAPE EVALUATION SYSTEM
2023
Abstract. This paper describes a system, currently being designed, for both perceptual analysis and aesthetic evaluation of a landscape. The choice of this topic is motivated by the fact that systems related to landscape visibility (e.g. Geographical Information Systems (GIS) for visual impact assessment) are not fully satisfactory when it comes to assessing the aesthetic appearance. They mainly analyse geometric aspects, such as the width of visual basins or the interference of visual trajectories, which can be expressed by objective and comparable parameters. Instead, for effective landscape knowledge and protection, it is important to consider other factors that cannot be easily measured…

Landslides and gully slope erosion on the banks of the Gauja River between the towns of Sigulda and Līgatne
2013
This study examines contemporary and past slope erosion processes in the Gauja River valley and adjoining area between the towns of Sigulda and Līgatne. In the field survey landslides and gullies were mapped. Spatial landslide and gully data were correlated with the landslide- and gully-related features (local relief, slope lithology, slope form, slope angle and density of gullies). A novel approach was applied to establish the relationships between slope processes and factors influencing them. This approach uses correlation between raster values of landslide-related factors in specific slope sections and the number of slope processes in these sections to determine the areas prone to slope …
Pamięć a język. Zarys relacji
2018
This article attempts to provide an answer to ąuestions concerning dimensions, aspects and outcomes of the contact between remembrance and language. The author also searches for a platform that could facilitate an effective and productive encounter of two research disciplines: memory studies and linguistics.
Contingent Policies, Complex Contexts and ROAD-MAPPING : Ways and Plays Forward
2023
This chapter first presents an overview of the complex language policy contexts of the internationalising universities. It starts from the multi-layeredness of university language settings and their political contingency and moves on to discuss the ROAD-MAPPING framework and the way it has acknowledged these complexities, both theoretically and empirically. After briefly observing the geographical and disciplinary contexts in the volume, the discussion moves on to the chapters’ contribution to ROAD-MAPPING and the ways in which the chapter authors discuss the benefits and drawbacks of the framework. The coda closes with a suggestion on how the framework could be used differently. For that, …
HIGH QUALITY TEXTURE MAPPING PROCESS AIMED AT THE OPTIMIZATION OF 3D STRUCTURED LIGHT MODELS
2019
Abstract. This article presents the evaluation of a pipeline to develop a high-quality texture mapping implementation which makes it possible to carry out a semantic high-quality 3D textured model. Due to geometric errors such as camera parameters or limited image resolution or varying environmental parameters, the calculation of a surface texture from 2D images could present several color errors. And, sometimes, it needs adjustments to the RGB or lightness information on a defined part of the texture. The texture mapping procedure is composed of mesh parameterization, mesh partitioning, mesh segmentation unwraps, UV map and projection of island, UV layout optimization, mesh packing and mes…
INTEGRATED SURVEYNG WITH MOBILE MAPPING SYSTEM, EGNOS, NTRK AND LASER TECHNOLOGIES IN THE PARK "NINNI CASSARA" IN PALERMO
2018
Abstract. This article summarizes the experience gained between 2012 and 2013 by the department of "Civil Engineering, Environmental, Aerospace and Materials" of University of Palermo on the integrated survey of Ninni Park Cassara Park in Palermo and the subsequent testing of methods, tools and techniques based on current research regarding the acquisition and processing of GNSS (Global Navigation Satellite System) data and laser-scanner. A fruitful time dedicated to the design of the survey has allowed us to become aware of the critical issues that the site presents because of its vast extent and diversity in size and number of the elements of which it is composed. The work has been addres…
VALUTAZIONI METRICHE DI PIATTAFORME APR PER RILIEVI E MODELLAZIONI 3D
2015
L’articolo descrive le esperienze condotte per la valutazione metrica di blocchi aerei acquisiti con differenti sistemi APR utilizzati nell’ambito del rilievo di BB.CC.. Il lavoro è stato svolto su due siti che differiscono per estensione e caratteristiche morfologiche utilizzando due diverse piattaforme APR, un sistema multi-rotore e un sistema ad ala fissa.
