Towards humane digitization : a wellbeing-driven process of personas creation
2019
Digital transformation is a process of digitizing the working and living environment in which people are at the center of digitization. In this paper, we present a personas-based guideline for system developers on how the humanization of digital transformation integrates into the design process. The proposed guideline uses the positive personas from the beginning as a basis for the transformation of the working environment into the digital form. We used the literature research as a preliminary study for the process of wellbeing-driven digital transformation design, consisting of questions for structuring the required information in the positive personas as well as a potential method that co…
Aggregation of the web performance of internal university units as a method of quantitative analysis of a university system: the case of Spain
2013
The aggregation of web performance data (page count and visibility) of internal university units could constitute a more precise indicator than the overall web performance of the universities and, therefore, be of use in the design of university web rankings. In order to test this hypothesis, a longitudinal analysis of the internal units of the Spanish university system was conducted over the course of 2010. For the 13,800 URLs identified, page count and visibility were calculated using the Yahoo! API. The internal values obtained were aggregated by university and compared with the values obtained from the analysis of the universities' general URLs. The results indicate that, although the c…
A Unified SVM Framework for Signal Estimation
2013
This paper presents a unified framework to tackle estimation problems in Digital Signal Processing (DSP) using Support Vector Machines (SVMs). The use of SVMs in estimation problems has been traditionally limited to its mere use as a black-box model. Noting such limitations in the literature, we take advantage of several properties of Mercer's kernels and functional analysis to develop a family of SVM methods for estimation in DSP. Three types of signal model equations are analyzed. First, when a specific time-signal structure is assumed to model the underlying system that generated the data, the linear signal model (so called Primal Signal Model formulation) is first stated and analyzed. T…
Towards a Trustful Digital World : Exploring Self-Sovereign Identity Ecosystems
2021
In the current global situation-burdened by, among others, a vast number of people without formal identification, digital leap, the need for health passports and contact tracking applications-providing private and secure digital identity for individuals, organizations and other entities is crucial. The emerging self-sovereign identity (SSI) solutions rely on distributed ledger technologies and verifiable credentials and have the potential to enable trustful digital interactions. In this human-centric paradigm, trust among actors can be established in a decentralized manner while the identity holders are able to own and control their confidential data. In this paper, we build on observations…
STRUMENTI E MATERIALI PER LA FABBRICAZIONE DIGITALE IN ARCHITETTURA/INSTRUMENTS AND MATERIALS FOR DIGITAL MANUFACTURING IN ARCHITECTURE
2017
Il contributo descrive strumenti e materiali oggi disponibili per la fabbricazione digitale in architettura, offrendo un’ampia panoramica sulle tecniche di stampa 3D e su come potrebbe rivoluzionare le costruzioni con importanti ricadute tecniche, economiche e sociali. Dal concetto di mass customization alla creazione dei Fab Lab, dal Contour Crafting alla tecnologia D- Shape e al progetto WASP assistiamo a un ripensamento del processo architettonico, ma anche a una ricerca sui materiali naturali, ecosostenibili e “programmabili”. The article describes tools and materials available today for digital manufacturing in architecture, offering a wide overview of 3D printing techniques and how it…
Automatable sample fabrication process for pump-probe X-ray holographic imaging
2014
Soft X-ray holography is a recently developed imaging technique with sub-50 nm spatial resolution. Key advantages of this technique are magnetic and elemental sensitivity, compatibility with imaging at free electron laser facilities, and immunity to in-situ sample excitations and sample drift, which enables the reliable detection of relative changes between two images with a precision of a few nanometers. In X-ray holography, the main part of the experimental setup is integrated in the sample, which consequently requires a large number of fabrication steps. Here we present a generic design and an automatable fabrication process for samples suitable, and optimized for, efficient high resolut…
Multilevel pattern generation by GaN laser lithography: an application to beam shaper fabrication
2006
The new GaN lasers represent a unique combination of compactness, reliability, energy efficiency, and short wavelength. With respect to the previous state of the art in direct laser write lithography, based on gas lasers, this is resulting in a breakthrough, and is opening the way to real desktop micropatterning. The field of diffractive optics can immediately benefit by the availability of a new breed of pattern generators, based on such sources, mainly for fast turnaround device development. This paper presents the technical advantages involved in the use of 405 nm GaN lasers for one-step multilevel patterning. Beam modulation, exposure control and overall process strategy are discussed. …
Uzņēmuma Digital Journey Facebook komunikācijas prakšu analīze un vērtējumi (2019.gada 1.novembris - 2020.gada 1.marts)
2020
Digitālais mārketings ir aktuāla tendence, ar kuras palīdzību uzņēmumiem ir iespējams sasniegt savu auditoriju, taču komunikāciju ir nepieciešams pielāgot mērķauditorijas nepieciešamībām un interesēm, citādi tā var būt nederīga. Tas nozīmē, ka uzņēmuma vadības viedoklis par komunikācijas stratēģiju var atšķirties no tā, kas patiesībā interesē mērķauditoriju. Bakalaura darba mērķis ir analizēt uzņēmuma Digital Journey Facebook komunikācijas praksi izvēlētajā laika posmā un noteikt uzņēmuma veidoto tēlu, balstoties uz K.Mertena tēla veidošanās teoriju. Pētījumā iegūti secinājumi par Digital Journey Facebook izmantotajām komunikācijas praksēm, veidoto tēlu un apkopoti ieteikumi veiksmīgai komu…
The overstated generational gap in online news use? A consolidated infrastructural perspective
2021
Recent research by Taneja et al. suggested that digital infrastructures diminish the generational gap in news use by counteracting preference structures. We expand on this seminal work by arguing that an infrastructural perspective requires overcoming limitations of highly aggregated web tracking data used in prior research. We analyze the individual browsing histories of two representative samples of German Internet users collected in 2012 ( N = 2970) and 2018 ( N = 2045) and find robust evidence for a smaller generational gap in online news use than commonly assumed. While short news website visits mostly demonstrated infrastructural factors, longer news use episodes were shaped more by …
The invisible setting of digital space: the Facebook case
2018
La neutralidad en la red no existe. El espacio digital puede ser adaptado de forma automática al perfil de cada usuario. Sin que este tenga que identificarse, las empresas de gestión de contenidos en Internet disponen de suficientes datos de cualquier individuo para poder filtrar los resultados de su búsqueda y personalizarlos, sin previo aviso, condicionando así su experiencia en la red. Esta investigación, de carácter exploratorio, aborda en primer lugar la descripción del espacio público digital. En segundo lugar, plantea una tipología de espacios digitales que se definen en función del grado de adaptación de los contenidos al usuario. Finalmente, presenta un análisis de caso de espacio …
