Planthology: an Application System for Plant Diseases Management
2017
The goals of modern agriculture are obtaining high yields that meet the increasing nutritional requirements of the World population. This is extremely difficult for three kind of reasons: i) the lands dedicated to agricultural use are strongly reduced in industrialized Countries; ii) farmers prefer an homogeneous product, because it is easier to manage, with consequent reduction of biodiversity, iii) globalization and climate change have led to the introduction of new pathogens and pest in environments other than original ones, resulting in serious production losses. The consequences of these problems, followed by not timely intervention leads to conditions that make not possible to obtain …
Shape optimization in contact problems based on penalization of the state inequality
1986
The paper deals with the approximation of optimal shape of elastic bodies, unilaterally supported by a rigid, frictionless foundation. Original state inequality, describing the behaviour of such a body is replaced by a family of penalized state problems. The relation between optimal shapes for the original state inequality and those for penalized state equations is established. peerReviewed
Informasjonsflyt ved mottak og respons på trygghetsalarmer : en casestudie for å undersøke hvilken betydning tilgang på informasjon og informasjonsfl…
2016
Masteroppgave i helse- og sosialinformatikk- Universitetet i Agder, 2016 The theme of this study is security alarms and information flow. The background for the study is estimates regarding an upcoming growing number of security alarms in municipal healthcare services, recommendations on the transition from analogue to digital security alarms, and reports on the current organization of the safety alarms of varying quality and low efficiency (Frantzen, 2014; Fensli, 2015 Kvernland-Berg, 2014). Purpose The aim of this study was to find what importance access to information and information flow had in the working process with security alarms for a future-oriented health services. Method The su…
"Ikke alle piloter flyr" : implementering av telemedisin i norske kommuner
2019
Masteroppgave helse- og sosialinformatikk HSI500 - Universitetet i Agder 2019 Running pilots is a widespread way of conducting innovations in the Norwegian health service, many of these projects are not implemented permanently or lead to lasting changes in services. Solutions based on Telemedicine are being tested, but the implementation rate does not match the existing ambitions. The aim of this study is to gain increased knowledge of some of the factors that are required for pilot projects in Telemedicine to go from pilots to permanent solutions, especially focused on stakeholders and their role. The thesis question is «What is the significance of different stakeholders in the municipalit…
Nonadherence in outpatient thrombosis prophylaxis with low molecular weight heparins after major orthopaedic surgery
2010
Background: According to some current guidelines, extended thromboprophylaxis after hip and knee arthroplasties is recommended. Outpatient prophylaxis with low molecular weight heparins (LMWH) is an important part of this prophylaxis, although the rates of adherence to these regimens is not known. Questions/purposes: We determined (1) the degree of nonadherence (NA) of patients with LMWH outpatient prophylaxis, and (2) whether specific independent factors explain NA. Methods: NA was determined by syringe count and by indirect and direct questions to patients. We defined six different NA indicators. To identify factors explaining LMWH NA, we used three different logistic regression models. R…
Effect of Sitting Posture on Sit-Skiing Economy in Non-disabled Athletes
2020
This study focused on resolving the differences in economy between two common sit-skiing postures used by disabled athletes, suspected to be the most and least effective. Ten experienced non-disabled male cross-country skiers went through an incremental testing protocol with an ergometer simulating double poling in two sitting postures “kneeing” and “knee-high.” The protocol consisted of 3 × 4 min steady-state stages (13, 22, and 34% of maximal sprint power output). Subjects' respiratory gases and heart rate were measured and blood lactate concentrations were determined. In addition, pulling forces and motion capture recordings were collected. Oxygen consumption was 15.5% (p < 0.01) higher …
Nanowire ordered Arrays for electrochemical sensing of H2O2
2016
In this work, we present the performance of nanostructured array of Cu for electrochemical sensors of hydrogen peroxide. Nanostructured sensors are obtained by template synthesis in commercial polycarbonate membranes. Arrays of Cu nanowires were fabricated through a displacement deposition reaction that permits to obtain nanostructures directly and without the use of an external power supply. To test the performance of nanostructured sensors, electrochemical experiments were carried out in an aqueous solution with different amounts of hydrogen peroxide. In order to obtain sensors with stable performance, we found that it is essential to increase wettability of the nanostructures through add…
An Ensemble Model for Consumer Emotion Prediction Using EEG Signals for Neuromarketing Applications.
2022
Traditional advertising techniques seek to govern the consumer’s opinion toward a product, which may not reflect their actual behavior at the time of purchase. It is probable that advertisers misjudge consumer behavior because predicted opinions do not always correspond to consumers’ actual purchase behaviors. Neuromarketing is the new paradigm of understanding customer buyer behavior and decision making, as well as the prediction of their gestures for product utilization through an unconscious process. Existing methods do not focus on effective preprocessing and classification techniques of electroencephalogram (EEG) signals, so in this study, an effective method for preprocessing and clas…
Panorámica de la desigualdad digital en España: operacionalización y dimensionamiento de las brechas digitales de accesibilidad, habilidades y formas…
2019
En este artículo, se realiza un análisis estadístico de la desigualdad digital en España a partir de una operacionalización de las tres brechas digitales más relevantes: (1) accesibilidad a los dispositivos TIC; (2) competencias y habilidades digitales; y (3) prácticas digitales y formas diferenciales de uso. La metodología es cuantitativa, basada en la última oleada (2018) de la encuesta sobre equipamientos tecnológicos en el hogar del INE (TIC-H), a partir de la cual se ha desarrollado un análisis comparativo por género, edad, nivel de estudios, situación laboral y tipo de hábitat residencial. Los resultados muestran cómo la desigualdad de acceso tiene actualmente más que ver con las moda…
Recovering a variable exponent
2021
We consider an inverse problem of recovering the non-linearity in the one dimensional variable exponent $p(x)$-Laplace equation from the Dirichlet-to-Neumann map. The variable exponent can be recovered up to the natural obstruction of rearrangements. The main technique is using the properties of a moment problem after reducing the inverse problem to determining a function from its $L^p$-norms.
