Complexes of organometallic compounds. LI. The correlation between 119Sn Mössbauer isomer shifts and partial atomic charges on tin in R3SnL compounds

1985

Abstract The 119Sn Mossbauer isomer shift parameters, δ, of compounds R3SnL (R = AlK, Ph; L = F, Cl, OH, OR′, CN, NCS, NCO, N3) have been correlated to partial atomic charges on tin QSn, calculated according to a valence state electronegativity equalization procedure carried out by the CHELEQ program. A unique δ/QSn correlation has been obtained for all the five-coordinated R3SnL species by using average δ parameters for the AlK3IV derivatives.

Increasing efficiency of photovoltaic systems under non-homogeneous solar irradiation using improved Dynamic Programming methods

2017

Abstract The paper presents a complete technique, based on the combination of algorithms, devoted to minimize losses and increase efficiency of Total Cross Tied (TCT) connected photovoltaic (PV) systems under non-homogeneous solar irradiation, based on irradiance equalization criterion. Irradiance equalization is achieved by changing the connections of the solar panels adaptively by a dynamic switching matrix so that total solar radiation on parallel circuits is the most equalized. In this paper, the authors introduce two algorithms. The first one is SmartChoice (SC) algorithm, which is combined with Dynamic Programming (DP) in order to create a hybrid method and obtain better results as co…

A False-Positive FFR: Drift and Failure to Equalize may cause Troubles!

2016

The results of FFR measurements determine further therapies. Therefore it is important that all steps necessary to obtain correct data are respected. We show the effect of an incorrect equalization.

Mathematical Morphology for Color Images: An Image-Dependent Approach

2012

This paper proposes one possibility to generalize the morphological operations (particularly, dilation, erosion, opening, and closing) to color images. First, properties of a desirable generalization are stated and a brief review is done on former approaches. Then, the method is explained, which is based on a total ordering of the colors in an image induced by its color histogram; this is valid for just one image and may present problems in smoothly coloured images. To solve these drawbacks a refinement consisting of smoothing the histogram and using a joint histogram of several images is presented. Results of applying the so-defined morphological operations on several sets of images are sh…

Fair Planning and Affordability Housing in Urban Policy. The Case of Syracuse (Italy)

2016

Equalization can be implemented in the planning process by means of several tools. The Syracuse’s Master Plan has used “urban negotiation” to obtain land for facilities and public infrastructure in different urban areas basing on the rule of the transfer of a portion of land in return for the building permission for the remaining part of each property to be developed. The Master Plan also aimed at providing social housing because the economic crisis has amplified the gap between housing market prices and household income. This study proposes an equalization and compensation model to support the urban negotiation for providing the indexes of a fair and convenient development of several inter…

MUNICIPAL FINANCE EQUALIZATION PROCESS IN LATVIA

2012

The municipal finance equalization calculations in Latvia presently take into account the demographic indicators, but they do not depict accurately the municipal finance requirements; in order to precisely determine these numbers, other consequential criteria should be accounted for as well, such as infrastructure or other aspects characterising the peculiarities or needs of a certain territory. Inclusion of these new criteria in the process of determining the need for financing could serve as the basis for improvements to the existing system. The purpose of this article is to analyze the municipal finance situation in Latvia, starting with 1998, to show the differences in their income and …

A novel framework for MR image segmentation and quantification by using MedGA

2019

BACKGROUND AND OBJECTIVES: Image segmentation represents one of the most challenging issues in medical image analysis to distinguish among different adjacent tissues in a body part. In this context, appropriate image pre-processing tools can improve the result accuracy achieved by computer-assisted segmentation methods. Taking into consideration images with a bimodal intensity distribution, image binarization can be used to classify the input pictorial data into two classes, given a threshold intensity value. Unfortunately, adaptive thresholding techniques for two-class segmentation work properly only for images characterized by bimodal histograms. We aim at overcoming these limitations and…

A multiscale approach to automatic and unsupervised retinal vessel segmentation using Self-Organizing Maps

2016

In this paper an automatic unsupervised method for retinal vessel segmentation is described. Self-Organizing Map, modified Fuzzy C-Means, STAPLE algorithms and majority voting strategy were adopted to identify a segmentation of the retinal vessels. The performance of the proposed method was evaluated on the DRIVE database.
