On some properties of g-frames and g-coherent states
2010
After a short review of some basic facts on g-frames, we analyze in details the so-called (alternate) dual g-frames. We end the paper by introducing what we call {\em g-coherent states} and studying their properties.
The qualifying study of metaphor as a vehicle of frame in the news texts about 11-m terrorist attacks (El País, The Guardian and Izvestia)
2018
espanolEl presente articulo aborda el estudio de la metafora como una estrategia de la interpretacion de los atentados terroristas perpetrados en Madrid el 11 de marzo de 2004 en tres diarios editados en distintas lenguas y en diferentes paises. El texto ofrece la mirada pluridisciplinar a la metafora, apoyandose en la interpretacion de dicha figura como una de las formas linguisticas de la interpretacion de la realidad en un texto periodistico y la llamada teoria de encuadre (framing). EnglishThis article includes the study of metaphor as a strategy for interpreting the terrorist attacks perpetrated in Madrid on March 11, 2004 in three newspapers published in different languages in differe…
Sistemas de visión frameless, procesado hardware AER y procesado de la información mediante eventos
2018
La democratización de las cámaras de visión en nuestra vida cotidiana ha tomado fuerza pues cada vez son más pequeñas, con procesamiento más potente y menor consumo de energía, facilitando su implementación en diferentes dispositivos de tamaños que hasta hace pocos años se creía imposible y que ahora encontramos en casi cualquier lugar. Existen aplicaciones de visión artificial en las que el desempeño apenas se ha visto mejorado en las últimas décadas, aquellas en las que prima la velocidad de procesamiento más allá de la resolución y calidad de la imagen. Estas aplicaciones las abarca principalmente el sector de la industria de la manufactura y procesos, con aplicaciones de lectura de códi…
A Framework to Support Business-IT Alignment in Enterprise Architecture Decision Making
2008
First published in the proceedings of the EBRF 2007 conference ”Research Forum to Understand Business in Knowledge Society”, September 25-27, Jyväskylä, Finland Business-IT alignment is one of the key concerns of general management and chief information officers. It is commonly recognized as an important instrument for realizing organizational effectiveness. Achieving business-IT alignment requires often change in the way managers regard IT and it demands co-operation between general and IT management. The challenge of aligning business- and IT-related concerns and requirements in architecture decision making situations is the focus of this study. As one possible solution, we present a fram…

Incorporation of zeolitic imidazolate framework (ZIF-8)-derived nanoporous carbons in methacrylate polymeric monoliths for capillary electrochromatog…
2017
A series of metal organic frameworks-derived nanoporous carbons originating from zeolitic imidazolate framework-8 (ZIF-8) crystals as precursors have been prepared via varying the preparation conditions. The ZIF-8-derived carbons were subsequently admixed in the methacrylate monomers containing polymerization mixtures and polymerized to obtain monolithic columns for capillary electrochromatography (CEC). The effect of particle size and content of the ZIF-8-derived carbon materials in the polymerization mixture on the performance of the hybrid monolithic columns was investigated in detail. The resulting composites were characterized using scanning electron microscopy. Using short time UV-ini…
Nanoparticle-Directed Metal–Organic Framework/Porous Organic Polymer Monolithic Supports for Flow-Based Applications
2017
A two-step nanoparticle-directed route for the preparation of macroporous polymer monoliths for which the pore surface is covered with a metal–organic framework (MOF) coating has been developed to facilitate the use of MOFs in flow-based applications. The flow-through monolithic matrix was prepared in a column format from a polymerization mixture containing ZnO-nanoparticles. These nanoparticles embedded in the precursor monolith were converted to MOF coatings via the dissolution–precipitation equilibrium after filling the pores of the monolith with a solution of the organic linker. Pore surface coverage with the microporous zeolitic imidazolate framework ZIF-8 resulted in an increase in su…
Joint Methodology for the Identification and Assessment of Groundwater Dependent Terrestrial Ecosystems in Estonia and Latvia
2020
Dynamic interactions between ground- and surface water are widely known, but the role of groundwater in terrestrial and aquatic ecosystems is often poorly understood and documented due to the spatiotemporal complexity. Many countries have not yet completed the assessment of groundwater dependent ecosystems (GDEs). GDEs are valuable ecosystems that depend on groundwater input and can not be considered and assessed separately. Changes in the quantity and chemical composition of groundwater recharge may result in significant and permanent damage on GDE flora and fauna. Aquifers are dynamic systems which are not subject to administrative boundaries and borders, therefore should be managed in cl…
Spatial and temporal variability of diatom and macroinvertebrate communities: How representative are ecological classifications within a river system?
2012
Evaluation of river condition is complicated by dynamic relationships between river assemblages and their environment. We assessed variation of ecological status classifications of stream diatom and macroinvertebrate communities within a boreal river system. We specifically examined whether results of ecological classifications are concordant across taxonomic groups and among main channel and headwater side tributaries of this river system. We further assessed whether ecological classifications are stable from year to year and whether classifications show predictable relationships to major stressor gradients. The estimated ecological condition varied considerably among and between reaches o…
