Biomass estimator for NIR image with a few additional spectral band images taken from light UAS
2012
A novel way to produce biomass estimation will offer possibilities for precision farming. Fertilizer prediction maps can be made based on accurate biomass estimation generated by a novel biomass estimator. By using this knowledge, a variable rate amount of fertilizers can be applied during the growing season. The innovation consists of light UAS, a high spatial resolution camera, and VTT's novel spectral camera. A few properly selected spectral wavelengths with NIR images and point clouds extracted by automatic image matching have been used in the estimation. The spectral wavelengths were chosen from green, red, and NIR channels.
High speed microfluidic prototyping by programmable proximity aperture MeV ion beam lithography
2013
Abstract Microfluidics refers to the science and technology for controlling and manipulating fluids that flow along microchannels. For the development of complex prototypes, many microfluidic test structures are required first. Normally, these devices are fabricated via photolithography. This technique requires a photomask for transferring a pattern to photoresists by exposing with UV light. However, this method can be slow when a new structure is required to change. This is because a series of photomasks are needed, which is time consuming and costly. Here, we present a programmable proximity aperture lithography (PPAL) technique for the development of microfluidic prototype in poly(methyl…
UAV-based hyperspectral monitoring of small freshwater area
2014
Recent development in compact, lightweight hyperspectral imagers have enabled UAV-based remote sensing with reasonable costs. We used small hyperspectral imager based on Fabry-Perot interferometer for monitoring small freshwater area in southern Finland. In this study we shortly describe the utilized technology and the field studies performed. We explain processing pipeline for gathered spectral data and introduce target detection-based algorithm for estimating levels of algae, aquatic chlorophyll and turbidity in freshwater. Certain challenges we faced are pointed out.
Methods for estimating forest stem volumes by tree species using digital surface model and CIR images taken from light UAS
2012
In this paper we consider methods for estimating forest tree stem volumes by species using images taken from light unmanned aircraft systems (UAS). Instead of using LiDAR and additional multiband imagery a color infrared camera mounted to a light UAS is used to acquire both imagery and the DSM of target area. The goal of this study is to accurately estimate tree stem volumes in three classes. The status of the ongoing work is described and an initial method for delineating and classifying treetops is presented.
Motivos de uso de las redes sociales virtuales: Análisis de perfiles de mujeres rurales
2015
En el presente trabajo, se muestran los resultados de una investigación cuyo objetivo es conocer los motivos de uso de las redes sociales virtuales de las mujeres rurales y determinar perfiles en función de sus respuestas. Para ello, se realiza un estudio de encuesta, cuyo cuestionario se aplica a 478 mujeres de entornos rurales de Andalucía de 18 a 65 años. Los resultados muestran dos perfiles de mujeres en función de sus motivaciones de uso de las redes, encontrando que las que usan las redes con una mayor variedad de motivos, muestran mayores niveles en intensidad, habilidad y autonomía de uso, mientras que las que la usan exclusivamente por motivos relacionales presentan niveles inferio…
Algunos aspectos de la asimilación de la teoría del contagio animado en la España del siglo XIX
1999
La aceptación de la teoría del contagio animado en España durante el siglo XIX llevó a la superación de la teoría miasmática como explicación del origen de las enfermedades infecciosas y a la integración de las explicaciones parasitológicas de la sarna, la helmintiasis y la tiña, con la vacunación antivariólica y los datos aportados por la nueva microbiología. Ello permitió la resolución de problemas como la infección quirúrgica y la fabricación de sueros y vacunas. El último cuarto de siglo vio la consolidación definitiva de esta teoría, con la aparición de una legislación y unas instituciones específicas dedicadas a la microbiología, así como las primeras exposiciones sistemáticas de la n…
Axiology of the historial city and the cap rate. The case of the old town of Ragusa Superiore
2017
Il contributo affronta il tema del ruolo che il mercato immobiliare assume nei processi di valorizzazione dei tessuti urbani storici nella logica dell’approccio al valor capitale. L’articolazione, eterogeneità e multi-contestualità del patrimonio immobiliare della città storica, la molteplicità delle relazioni tra valori e prezzo, la complessa dialettica fondo/flusso, l’eterogeneità dei profili dei soggetti economici che interagiscono nel mercato, danno vita ad un assortimento di approcci all’investimento immobiliare che in questo contributo, attraverso l’analisi del saggio di capitalizzazione si intendono rappresentare. La convergenza tra valori di contesto e potenzialità inespresse da una…
Les tecnologies de la informació i la comunicació a l'àrea de Llengua en Educació Primària
2015
Estem davant d’un moment històric en què la construcció de la societat i la cultura es fa des d’un paradigma sociocontructivista. Més si cap amb la irrupció de les Tecnologies de la Informació i la Comunicació (TIC) que permeten arribar, de manera immediata, la informació i el coneixement a qualsevol racó del món i persona. Aquesta ferramenta amb un impacte tan gran a nivell global i col·lectiu, és clar que també ho és a nivell individual. Però, qui s’ha parat a atendre aquesta qüestió des de la base del funcionament del món que és l’Educació? Mitjançant el TFG que es presenta a continuació, recorrerem històricament l’evolució de les TIC, així com les influències d’aquestes dintre de l’àmbi…
La marque ou une mention innovante permet-elle de compenser l'impossibilité de toucher le produit par les consommateurs ?
2015
Packaging or methods of distance selling prevent consumers from touching the products and therefore from evaluating them properly. Thus the aim of this research is to observe whether extrinsic information, such as brand or innovative cue, can compensate this lack of sensory information and so improve the hedonic evaluation. An experiment conducted on 110 subjects with two fabrics shows that consumers evaluate them more positively when they observe them with an extrinsic information than when they observe them without this information, and that this improvement is greater than that obtained when we allow them to assess the fabrics by the touch in addition to the mere sight.
Oded Ezer, Il mirabolante costruttore di lettere e alfabeti
2008
Tutte le altezze, profondità e larghezze delle cose tangibili e naturali: paesaggi, tramonti, il profumo del fieno, il ronzio delle api, la bellezza che dipende dalle ciglia, ma è erroneamente attribuita agli occhi; tutte le incommensurabili emozioni e tutti i moti dell'animo umano, che paiono senza limiti; cose e pensieri orrendi, terribili e misteriosi, ma anche belli; tutto questo è compreso, contenuto e ordinato in un piccolo guazzabuglio di lettere. Ventisei simboli! Così scriveva nel 1923 Francis Maynell, il tipografo inglese che aveva conquistato il mondo con ventisei soldati di piombo, i quali altri non erano che i caratteri dell'alfabeto necessari alla produzione della Nonesuch Pre…
