Biodiversity dynamics and their driving factors during the Cretaceous diversification of Spatangoida (Echinoidea, Echinodermata)
2004
Abstract Variations in recorded diversity over time present a scrambled signal that is modulated by a large number of variables: the potential of particular life forms to generate evolutionary innovations, external constraints induced by the environment in its broad sense, the heterogeneity of the fossil record and the analytical artefacts due to sampling bias. A key question is how to characterise and quantify the separate input of any given factor in the overall diversity signal. This paper explores the structure of diversity data for spatangoid heart urchins and the sensitivity of recorded diversity to different factors of analytical bias (length of geological periods, proportion of pala…
Characterization of Leaf Essential Oil Composition of Homozygous and HeterozygousCitrus clementinaHort. Extan. and its Ancestors
2013
Clementine is a natural tangor, resulting from an interspecific cross between mandarin and sweet orange. Gametic embryogenesis, allowing the single-step development of complete homozygous line from the heterozygous parents, increases the efficiency of perennial crop breeding programs. Tri-haploids have been regenerated through pollen embryogenesis (specifically, by anther culture) of Citrus clementina Hort. ex Tan., cv. Nules. Two of them (HOMO1 and HOMO2) have been acclimatized and grafted in vivo in 2000. Research regarding the chemical characteristics of plant regenerated by pollen embryogenesis or gynogenesis are useful to study the “gametoclonal variation”, as well as for further appli…
Pricing of Forwards and Options in a Multivariate Non-Gaussian Stochastic Volatility Model for Energy Markets
2013
In Benth and Vos (2013) we introduced a multivariate spot price model with stochastic volatility for energy markets which captures characteristic features, such as price spikes, mean reversion, stochastic volatility, and inverse leverage effect as well as dependencies between commodities. In this paper we derive the forward price dynamics based on our multivariate spot price model, providing a very flexible structure for the forward curves, including contango, backwardation, and hump shape. Moreover, a Fourier transform-based method to price options on the forward is described.

Otrajā nodaļā tiek teorētiski aplūkota informācijas sistēmu būtība, to galvenie pamatelementi, klasificēšanas iespējas, izstrādes tehnoloģijas un kvalitatīvi izstrādātu informācijas sistēmu rādīt…
FOR SOMETHING THAT WAS OURS… NOW IT BELONGS TO ALL OF HUMANITY”: WORLD HERITAGE AS THE EXPRESSION OF CONFLICTS
2020
Resumen: En este artículo nos interesa reflexionar sobre la naturaleza conflictiva del patrimonio, que suele ser silenciada por su potente imaginario como capital cultural, económico y social y como signo de distinción. A través de un análisis detallado del proceso mediante el cual el tango y las fallas pasaron a formar parte de la Lista Representativa del Patrimonio de la Humanidad, nos adentramos en las dimensiones hegemónicas y de los procesos patrimoniales, así como en la esencia beligerante de las resistencias locales que se enfrentan a las lógicas del patrimonio neoliberal. Estos casos nos permiten vislumbrar las relaciones conflictivas que a menudo se establecen entre distintas lógic…
Riannodare passato e presente con le foto d’archivio. Ricostruzione della chiesa delle Stimmate di Palermo
2021
La restituzione prospettica è stata pressoché ignorata nelle ricerche incentrate sulla ricostruzione di architetture e contesti urbani da foto d’archivio, a causa dell’ampio margine di approssimazione che caratterizzava il processo di restituzione condotto con gli strumenti tradizionali del disegno. Gli strumenti digitali per la rappresentazione riducono sensibilmente il margine di approssimazione e permettono di ricostruire direttamente nello spazio tridimensionale le opere che compaiono in una singola immagine fotografica. Il caso studio prescelto è la chiesa delle Stimmate di Palermo, demolita alla fine del XIX secolo per la costruzione del teatro Massimo, principale teatro lirico della …
CONSIDERAZIONI TEORICHE E PRATICHE SUL METODO DEL MASSIMO RETTANGOLO CIRCOSCRITTO PER LA VALUTAZIONE DELL’AMPIEZZA DELLA TENSIONE TANGENZIALE NEI CRI…
2012
The multiaxial fatigue criteria based on the approach of the critical plane require the determination of the amplitude of the alternating shear stress τ aacting on different planes passing through the point of the material analyzed. In the case of non-proportional stresses the shear stress vector varies both in modulus and direction and its tip describes a curvedefined loading path. In these cases τ ais identified and evaluated by means of special procedures the most recent, and apparently more effective, of which is that of the Maximum Circumscribed Rectangle (MCR) to the loading path itself. In particular τ ais equal to the length of the diagonal of the MCR. In this paper, the MCR method …
Energy efficiency in wireless networks
2013
Tämä pro gradu -työ on sekundääritutkimuksena tehty kirjallisuuskatsaus energiatehokkuuden tarkastelusta langattomissa verkoissa. Työssä tarkastellaan erilaisia mobiiliverkkojen energiansäästömahdollisuuksia. Pääpaino työssä on suunnattu erityisesti 3G ja LTE -verkkoihin, kuitenkin eksoottisempiakaan verkkoja unohtamatta. Työ alkaa erilaisten mobiiliverkkojen energiansäästösyiden ja tutkimusmotivaattoreiden tunnistamisella ja jatkuu langattomien verkkojen energian kulutuksen jaotuksella, sekä erilaisten energiansäästömahdollisuuksien vertailuilla. Työn empiirisessä osassa nostetaan lisäksi esille lyhyt Octave-simulaatio kollaboroivan mobiilipilven noodien energiansa…
