Toward Quaternary QCA : Novel Majority and XOR Fuzzy Gates

2022

As an emerging nanotechnology, quantum-dot cellular automata (QCA) has been considered an alternative to CMOS technology that suffers from problems such as leakage current. Moreover, QCA is suitable for multi-valued logic due to the simplicity of implementing fuzzy logic in a way much easier than CMOS technology. In this paper, a quaternary cell is proposed with two isolated layers because of requiring three particles to design this quaternary cell. Moreover, due to the instability of the basic gates, the three particles cannot be placed in one layer. The first layer of the proposed two-layer cell includes a ternary cell and the second one includes a binary cell. It is assumed that the over…

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.

El pueblo de la Confederación suiza: su significación constitucional y composición

2016

ResumenEl pueblo, que se expresa como cuerpo electoral (o conjunto de ciudadanos que tras la mayoría de edad pueden ejercer los derechos políticos), es elemento constitutivo y constituyente de la Confederación (tanto en su dimensión federal como en la cantonal) y, a la vez, órgano supremo y primera fuente de legitimidad del ordenamiento constitucional suizo. El pueblo participa en las decisiones que comportan incorporaciones al mismo dando lugar en ocasiones a conflictos con las decisiones de las autoridades competentes.AbstractThe people who are defined as the electorate (the citizens who after the age of majority exercise in reality their political rights), are the constitutive and consti…

An Algorithm for Discretization of Real Value Attributes Based on Interval Similarity

2013

Discretization algorithm for real value attributes is of very important uses in many areas such as intelligence and machine learning. The algorithms related to Chi2 algorithm (includes modified Chi2 algorithm and extended Chi2 algorithm) are famous discretization algorithm exploiting the technique of probability and statistics. In this paper the algorithms are analyzed, and their drawback is pointed. Based on the analysis a new modified algorithm based on interval similarity is proposed. The new algorithm defines an interval similarity function which is regarded as a new merging standard in the process of discretization. At the same time, two important parameters (condition parameterαand ti…

Weakly coupled map lattice models for multicellular patterning and collective normalization of abnormal single-cell states

2017

We present a weakly coupled map lattice model for patterning that explores the effects exerted by weakening the local dynamic rules on model biological and artificial networks composed of two-state building blocks (cells). To this end, we use two cellular automata models based on: (i) a smooth majority rule (model I) and (ii) a set of rules similar to those of Conway's Game of Life (model II). The normal and abnormal cell states evolve according with local rules that are modulated by a parameter $\kappa$. This parameter quantifies the effective weakening of the prescribed rules due to the limited coupling of each cell to its neighborhood and can be experimentally controlled by appropriate e…

A language socialisation perspective on Swedish immersion in Finland : Students, teachers, and parents as key actors

2022

Abstract This retrospective review applies a language socialisation perspective in examining the findings of a four-year research project on Swedish immersion in Finland. Findings from nine sub-studies within the project are reported with a point-of-view from three key actors’ (teachers, students, and parents) language socialisation processes. Results show that a special feature of immersion teacher socialisation is its continuous attention toward the additive multilingual nature of immersion education, which requires sustained attention to multilingual language use and development. Students in Swedish immersion are socialised into the use of multiple languages in school and act as socialis…

Same work, lower grade? Student ethnicity and teachers’ subjective assessments

2010

Previous research shows that ethnic minority students perform poorer in school when they are taught by ethnic majority teachers. Why this is the case was unclear. This paper focuses on one important potential explanation: I examine whether ethnic majority teachers grade minority and majority students differently for the same work. Using an experiment, I rule out the existence of such a direct grading bias. I do find indirect evidence for alternative explanations: teachers report lower expectations and unfavorable attitudes that both likely affect their behavior towards minority students, potentially inducing them to perform below their ability level. Effects of having majority teachers on m…

PS-039 DokuPIK – Pharmaceutical interventions: Do ward pharmacists know how to document?

2014

Background The internet-based categorical, hierarchical documentation system for routine pharmaceutical interventions (PIs) DokuPIK is widely used especially among German ward-based pharmacists. Purpose To conduct a survey-based study on its clinical usability. Materials and methods Out of 498 registered DokuPIK users, 37 volunteered to independently evaluate 24 standardised case reports 1 between 01–03 2012. Case evaluation was restricted to the reason for PI and was performed based on 26 given survey items with no limit on the number of items chosen. Ratings were conducted electronically and anonymously. In order to define meaningful reference item selections, majority decisions made by 5…

Detection of Ventricular Fibrillation Using the Image from Time-Frequency Representation and Combined Classifiers without Feature Extraction

2018

Due the fact that the required therapy to treat Ventricular Fibrillation (V F) is aggressive (electric shock), the lack of a proper detection and recovering therapy could cause serious injuries to the patient or trigger a ventricular fibrillation, or even death. This work describes the development of an automatic diagnostic system for the detection of the occurrence of V F in real time by means of the time-frequency representation (T F R) image of the ECG. The main novelties are the use of the T F R image as input for a classification process, as well as the use of combined classifiers. The feature extraction stage is eliminated and, together with the use of specialized binary classifiers, …
