A Fuzzy Approach to the Role of Symmetry in Shape Formation: The Illusion of the Scalene Triangle
2009
The main purposes of this work are to demonstrate the role of directional symmetry as a second order principle that polarizes the perception of the shape and to show how this preference can be easily encoded in an algorithm using a fuzzy operator for symmetry detection. The role of grouping in influencing shape perception and the role of directional symmetry was demonstrated through small triangles that create a large triangle. The specific questions answered in the psychophysical experiments were the following: Can the grouping by similarity influence both the pointing and the shape of the small and the large isosceles triangles? Conversely, can the shape of the large triangle influence th…
Biological Nutrient Removal Model No. 2 (BNRM2): a general model for wastewater treatment plants
2013
This paper presents the plant-wide model Biological Nutrient Removal Model No. 2 (BNRM2). Since nitrite was not considered in the BNRM1, and this previous model also failed to accurately simulate the anaerobic digestion because precipitation processes were not considered, an extension of BNRM1 has been developed. This extension comprises all the components and processes required to simulate nitrogen removal via nitrite and the formation of the solids most likely to precipitate in anaerobic digesters. The solids considered in BNRM2 are: struvite, amorphous calcium phosphate, hidroxyapatite, newberite, vivianite, strengite, variscite, and calcium carbonate. With regard to nitrogen removal via…
Design and Validation of a FPGA-Based HIL Simulator for Minimum Losses Control of a PMSM
2021
This work examines the FPGA programmable logic platforms applied to minimum losses control of a Permanent Magnet Synchronous Motor (PMSM), which represents a flexible solution for the implementation of an advanced digital control algorithm, given their intrinsic parallel structure and the capability to be directly reprogrammable in the field. In particular, design and validation of a FPGA-based Hardware-In-the-Loop (HIL) simulator is proposed, by investigating about data format, quantization and discretization effects and other issues arising during the experimental validation of a controller prototype, in order to reduce the embedded software development cycle and test control systems. The…
The clinical relevance of low-density-lipoproteins size modulation by statins.
2006
The predominance of small, dense low density lipoproteins (LDL) has been accepted as an emerging cardiovascular risk factor by the National Cholesterol Education Program Adult Treatment Panel III; in fact, LDL size seems to be an important predictor of cardiovascular events and progression of coronary heart disease. Several studies have also shown that the therapeutical modulation of LDL size is of great benefit in reducing the risk of cardiovascular events. Hypolipidemic treatment is able to alter LDL subclass distribution and statins are currently the most widely used lipid-lowering agents. Statins are potent inhibitors of hydroxy-methyl-glutaryl-coenzyme A reductase, the rate-limiting en…
Viejos paisajes, nuevas tecnologías: una reconstrucción del paisaje Holoceno con gvSIG y sextante
2010
Con el objetivo de reconstruir el paisaje geomorfológico de finales del cuaternario y comienzos del Holoceno, se ha utilizado gvSIG y sextante para intentar establecer el paisaje a partir de los datos de campoarquelógicos y geomorfológicos recogidos durante una veintena de años en la cuenca media y alta del río Serpis. La evolución cuaternaria es la historia de un vaciado (erosión + denudación) de los valles del curso alto y medio del Serpis, con algunas interrupciones (fases de sedimentación). Testigos de dicha evolución son las terrazas fluviales adscritas por nosotros a diversos periodos del Cuaternario. La combinación de métodos tradicionales y el trabajo con el uso de herramientas SIG …
Una metodologia per la suddivisione di un'area geografica regionale in Sistemi Turistici Locali.
2005
In questo lavoro si propone un metodo per a®rontare e risolvere il problema del dimensionamento e della localizzazione ottimali dei Sistemi Turistici Locali. A tal ¯ne, l'applicazione del modello proposto sull'area territoriale in esame viene iservata ad una fase in cui sono stati giµa presi in considerazione opzioni e vincoli trategici; viene presentato, invero, un criterio per la de¯nizione della gerarchia delle unitµa territoriali, che consente, d'altra parte, una sensibile riduzione delle alterna- ive ammissibili nella de¯nizione dei sistemi turistici, che avviene proponendo uno peci¯co algoritmo. l problema di ottimizzazione µe risolto successivamente mediante un procedimento di ricerc…

Daudzkanālu skaņas kodeka funkciju testu automatizācija
2017
Dokuments sniedz ieskatu skaņas pults un kodeka testu automatizācijā. Dokumentā aprakstītā programmatūra ir šo iekārtu funkciju testu automatizācijas skripti. Šo skriptu mērķis ir atvieglot testēšanas procesu. Testu automatizācija nodrošina ātrāku, vienkāršāku un efektīvāku testēšanas procesu. To galvenā priekšrocība ir iespēja tos atkārtoti izmantot, piemēram, kādas funkcijas izmaiņu gadījumā – tie nodrošina to, ka kādu funkciju izmaiņu gadījumā var ātri un ērti pārbaudīt vai konkrētās izmaiņas nav izmainījušas kādas citas funkcijas darbību un ļauj ātrāk atrast, identificēt un salabot jebkādas šāda veida problēmas. Gala rezultāts uzlabo iekārtu testu nodrošinājumu un uzlabo izstrādes proce…
Telpiskās modelēšanas programmas SketchUp izmantošana sākumskolā starppriekšmetu saiknes īstenošanai

Side effect management during immune checkpoint blockade using CTLA-4 and PD-1 antibodies for metastatic melanoma – an update
2020
CTLA-4 and PD-1 play a key role in tumor-induced downregulation of lymphocytic immune responses. Immune checkpoint inhibitors have been shown to alter the immune response to various cancer types. Anti-CTLA-4 and anti-PD-1 antibodies affect the interaction between tumor, antigen-presenting cells and T lymphocytes. Clinical studies of the anti-CTLA-4 antibody ipilimumab and the anti-PD-1 antibodies nivolumab and pembrolizumab have provided evidence of their positive effects on overall survival in melanoma patients. Combined treatment using ipilimumab and nivolumab has been shown to achieve five-year survival rates of 52 %. Such enhancement of the immune response is inevitably associated with …
