SAP UI5 lietotņu pirmkoda automatizētas pārstrādes rīka izstrāde
2018
Kvalifikācijas darbā tika izstrādāts rīks SAP UI5 lietotņu pirmkoda automatizētai pārveidei, kas veic SAP UI5 JavaScript koda analīzi un aizvieto novecojušās un mazāk efektīvās sinhronās moduļu ielādes metodes ar aktuālajām un tīmekļa kontekstā efektīvākām asinhronajām moduļu ielādes metodēm, kā arī veic koda izmaiņas, kuru nepieciešamība izriet no iepriekšminētās metožu aizvietošanas. Izstrādātā rīka mērķis ir padarīt automātisku, ātru un pabeigtu, bez cilvēciskām kļūdām, šādas pārstrādes procesu tām lietotnēm un projektiem, kuru izstrāde ir aizsākusies pietiekami sen, lai kodu būtu nepieciešams šādi aktualizēt. Rīks tika izstrādāts izmantojot SAP UI5 ietvaru lietotāja saskarnes pusē, Node…
Evolution in African Marantaceae - Evidence from Phylogenetic, Ecological and Morphological Studies
2011
Abstract The Marantaceae (∼530 spp.) are one of the most species rich families within the order Zingiberales which incites the search for evolutionary factors favoring speciation. A positive influence on their divergence is ascribed to their unique explosive pollination mechanism which has been proposed to be a key innovation. To test this hypothesis phylogenies of the two major African clades (Sarcophrynium and the Marantochloa clade) were established based on data from nuclear (ITS, 5S) and chloroplast (trnL/trnL-F) DNA for an almost complete taxon sample. The phylogeny was used to parsimoniously reconstruct morphological and ecological traits and geographic distribution patterns. The res…
L'albero della vita
2020
Le poesie sono come le foglie dell'albero della vita. Liberano da molti dèmoni esorcizzandoli in una canzone. Poems are like the leaves of the tree of life. They free you from many daemons exorcising them in a song.
Responses of Prunus ferganensis, Prunus persica and two interspecific hybrids to moderate drought stress
2003
Prunus ferganensis (Kost. & Riab) Kov. & Kost, a close relative of the cultivated peach (Prunus persica (L.) Batsch.), is native to arid regions of central Asia and may possess traits valuable for improving drought tolerance of commercial peach varieties. One distinguishing feature of P. ferganensis is its prominent, elongated, unbranched leaf venation pattern, which behaves as a simple recessive trait in segregating populations of P. ferganensis x P. persica hybrids. To understand whether this trait could be used as a marker in breeding for drought tolerance, we investigated the association between leaf morphological and physiological parameters related to drought response in P. ferganensi…
A taxonomic revision of westernEupholidopterabush crickets (Orthoptera: Tettigoniidae): testing the discrimination power of DNA barcode
2013
The genus Eupholidoptera includes 46 Mediterranean species distributed from Turkey to Greece, Italy and southern France. In the eastern part of its range, Eupholidoptera has been considered to consist of several distinct species, while in the Balkans and Italian peninsula only E. chabrieri has been recognized. However, the status of some Italian populations, confined to particular geographic areas, remains uncertain. To investigate the delimitation of the Italian taxa of Eupholidoptera, we performed both morphological and molecular analyses. Morphological analysis was carried out by considering diagnostic characters usually used to distinguish different taxa, such as the shape of titillator…
Automatic detection and agronomic characterization of olive groves using high-resolution imagery and LIDAR data
2014
The Common Agricultural Policy of the European Union grants subsidies for olive production. Areas of intensified olive farming will be of major importance for the increasing demand for oil production of the next decades, and countries with a high ratio of intensively and super-intensively managed olive groves will be more competitive than others, since they are able to reduce production costs. It can be estimated that about 25-40% of the Sicilian oliviculture must be defined as “marginal”. Modern olive cultivation systems, which permit the mechanization of pruning and harvest operations, are limited. Agronomists, landscape planners, policy decision-makers and other professionals have a grow…
OPTIMIZING STOCHASTIC SUSCEPTIBILITY MODELLING FOR DEBRIS FLOW LANDSLIDES: MODEL EXPORTATION, STATISTICAL TECHNIQUES COMPARISON AND USE OF REMOTE SEN…
Il presente lavoro di ricerca è stato sviluppato al fine di approfondire approcci metodologici nell'ambito della sucscettibilità da frana. In particolare, il tema centrale della ricerca è rappresentato dal tema specifico dell'esportazione spaziale di modelli di suscettibilità nell'area mediterranea. All'interno del topic specifico dell'esportazione di modelli predittivi spaziali sono state approfondite tematiche relative all'utilizzo di differenti algoritmi o di differenti sorgenti, derivate da DEM o da coperture satellitari. The present work has been developed in order to enhance current methodological approaches within the big picture of the landslide susceptibility. In particular, the ce…
A Scheme for Continuous Input to the Tsetlin Machine with Applications to Forecasting Disease Outbreaks
2019
In this paper, we apply a new promising tool for pattern classification, namely, the Tsetlin Machine (TM), to the field of disease forecasting. The TM is interpretable because it is based on manipulating expressions in propositional logic, leveraging a large team of Tsetlin Automata (TA). Apart from being interpretable, this approach is attractive due to its low computational cost and its capacity to handle noise. To attack the problem of forecasting, we introduce a preprocessing method that extends the TM so that it can handle continuous input. Briefly stated, we convert continuous input into a binary representation based on thresholding. The resulting extended TM is evaluated and analyzed…
Monte Carlo simulation in phylogenies: an application to test the constancy of evolutionary rates.
1994
Monte Carlo simulation has commonly been used in phylogenetic studies to test different tree-reconstruction methods, and consequently, its application for testing evolutionary models can be considered as a natural extension of this usage. Repetitive simulation of a given evolutionary process, under the restrictions imposed by the model to be tested, along a determinate tree topology allow the estimate of probability distributions for the desired parameters. Next, the phylogenetic tree can be reconstructed again without the constraints of the model, and the parameter of interest, derived from this tree, can be compared to the corresponding probability distribution derived from the restricted…
RETROVESICAL MASS IN MEN
1999
We review the differential diagnosis and treatment of retrovesical masses in men.During the last 8 years 21 male patients 3 to 79 years old (mean age 47.1) presented with symptoms or signs of a retrovesical mass. Clinical features and diagnostic findings were reviewed, and related to surgical and histopathological findings.The retrovesical masses included prostatic utricle cyst in 3 cases, prostatic abscess in 1, seminal vesicle hydrops in 6, seminal vesicle cyst in 2, seminal vesicle empyema in 3, large ectopic ureterocele in 1, myxoid liposarcoma in 1, malignant fibrous histiocytoma in 1, fibrous fossa obturatoria cyst in 1, hemangiopericytoma in 1 and leiomyosarcoma in 1. In 17 patients …
