Digital health interventions in children with asthma
2020
Abstract Although healthcare providers are actively involved in offering education, information and interventions for asthmatic patients, medication and therapeutic adherence remain low in the paediatric population, with estimates suggesting that adherence rates hover below 50%. A range of available digital health interventions has been explored in paediatric asthma with promising but variable results, limiting their widespread adoption in clinical practice. They include emerging technologies that yield the advantage of tracking asthma symptoms and medications, setting drug reminders, improving inhaler technique and delivering asthma education, such as serious games (video games designed fo…
Tree Species Identification Using 3D Spectral Data and 3D Convolutional Neural Network
2018
In this study we apply 3D convolutional neural network (CNN) for tree species identification. Study includes the three most common Finnish tree species. Study uses a relatively large high-resolution spectral data set, which contains also a digital surface model for the trees. Data has been gathered using an unmanned aerial vehicle, a framing hyperspectral imager and a regular RGB camera. Achieved classification results are promising by with overall accuracy of 96.2 % for the classification of the validation data set. nonPeerReviewed
Feasibility of a personal health technology-based psychological intervention for men with stress and mood problems: Randomized controlled pilot trial
2013
BackgroundWork-related stress is a significant problem for both people and organizations. It may lead to mental illnesses such as anxiety and depression, resulting in increased work absences and disabilities. Scalable interventions to prevent and manage harmful stress can be delivered with the help of technology tools to support self-observations and skills training. ObjectiveThe aim of this study was to assess the feasibility of the P4Well intervention in treatment of stress-related psychological problems. P4Well is a novel intervention which combines modern psychotherapy (the cognitive behavioral therapy and the acceptance and commitment therapy) with personal health technologies to deliv…
AN INTEGRATED APPROACH FOR THE HCl AND METALS RECOVERY FROM WASTE PICKLING SOLUTIONS: PILOT PLANT DESIGN AND OPERATIONS
2020
Pickling is one of the key steps in the hot-dip galvanizing process, where HCl solutions are largely used to remove metal oxides from metallic surfaces, thus generating spent waste liquors containing high concentrations of metals and acid. Disposal of the industrial pickling waste dramatically affects the hot-dip galvanizing industry economics and environmental footprint. Thus, reducing strong acid waste disposal is one of the most beneficial steps to enhance the process sustainability. Moreover, the continuous regeneration of pickling solutions enhances pickling rate and process performance, also minimizing industrial wastewater disposal and chemicals consumption promoting the circular use…
DEVELOPMENT AND MODELING OF MEMBRANE PROCESSES FOR THE REGENERATION OF ACID PICKLING SOLUTIONS
2021
The doctoral thesis focuses on a novel integrated process for the recovery and valorisation of acid and metal salts present in the waste solutions of the pickling process. The proposed process is based on the integration of two innovative membrane technologies, the Diffusion Dialysis and the Membrane Distillation, coupled with a reactive precipitation section. This hybrid process allows the recovery and the enhancement of waste solutions, as well as optimal operating conditions for the continuous pickling process, thus improving its efficiency. Hydrochloric acid recovery was assessed through a detailed study on the Diffusion Dialysis process by implementing a wide experimental campaign usin…
Sorption of V and VI group metalloids (As, Sb, Te) on modified peat sorbents
2016
AbstractThe present work investigates arsenic, antimony and tellurium sorption using iron modified peat. The results were obtained using batch tests and the sorption was studied as a function of initial metalloid concentration, pH and sorption time, as well as the presence of competing substances. The obtained results indicate that modification of peat with Fe compounds significantly enhances the sorption capacity of the sorbents used for sorption of arsenic, antimony and tellurium. The optimal pH interval for the sorption of Sb(III) is 6.5–9 and for As(V) and Sb(V) – 3–6, while As(III) and tellurium sorption using Fe-modified peat is favourable in a wider interval of 3–9. The presence of c…
Optimizing Nanopore-based microbiome sequencing for characterizing biotechnologically-relevant ecosystems
2022
La secuenciación de siguiente generación (NGS) ha cambiado completamente la manera en la que estudiamos el mundo microbiano. A lo largo de los últimos años, las plataformas Illumina han sido las más usadas para secuenciar ADN. No obstante, la secuenciación por nanoporos, un nuevo método impulsado por Oxford Nanopore Technologies (ONT), está incrementando gradualmente su popularidad dadas sus múltiples ventajas sobre las plataformas NGS. Estas ventajas incluyen la portabilidad y la capacidad para generar secuencias largas en tiempo real. A pesar de estos avances, la adopción de la secuenciación ONT se ha visto limitada por la elevada tasa de error asociada a esta tecnología en comparación co…
La mise en valeur du patrimoine archéologique et le tourisme durable Valorizzazione dei Beni Archeologici e Turismo Sostenibile
2014
Le thème du tourisme culturel intégré dans les sites archéologiques rentre dans les actions du projet A.P.E.R destinées à la mise en valeur du patrimoine culturel et archéologique et à l’encouragement des économies du territoire. Les biens culturels constituent en effet un « capital de valeur structurée » avec ses propres éléments distinctifs d’authenticité historique. Donner une centralité à ces importantes ressources du territoire, il signifie renforcer les processus de conservation et protection et en même temps augmenter le développement en termes de promotion et utilisation durable. Une telle perspective, qui voit les processus touristiques de type culturel comme possibles volants de d…
How Do Mobile ICTs Enable Organizational Fluidity : Toward a Theoretical Framework
2017
The focus of this theoretical paper is to investigate how mobile information and communication technologies (ICTs) give rise to the notion of organizational fluidity. Drawing upon previous literature, five affordances of mobile ICTs − mobility, connectedness, interoperability, identifiability, and personalization − are discussed. Delving into the concept of organizational fluidity, the paper captures three dimensions of organizational fluidity, namely, team fluidity, task fluidity, and control fluidity. The paper then develops propositions on how different combinations of the mobile ICT affordances influence each of the dimensions of organizational fluidity. The contributions and implicatio…
Mobile marketing and its implementations
2014
Latto, Joel Mobile marketing and its implementations Jyväskylä: University of Jyväskylä, 2014, 33 p. Information Systems Science, Bachelor’s Thesis Supervisor: Salo, Markus Mobile devices have become increasingly important marketing channel in recent years for all kinds of organizations. They allow marketers to bring forward relevant marketing information for the consumers based on location, purchase history, time and technology available. Although not brand new way of marketing, it is considered to be in its bloom right now, and it is expected to continue growing rapidly in near future. Some experts even say, that mobile marketing is just as vital to businesses as Internet marketing, and c…
