‎let $mathcal{a}$ be a unital banach algebra‎, ‎$mathcal{m}$ be a left $mathcal{a}$-module‎, ‎and $w$ in $mathcal{z}(mathcal{a})$ be a left separating point of $mathcal{m}$‎. ‎we show that if $mathcal{m}$ is a unital left $mathcal{a}$-module and $delta$ is a linear mapping from $mathcal{a}$ into $mathcal{m}$‎, ‎then the following four conditions are equivalent‎: ‎(i) $delta$ is a jordan left de...

Introduction: In patients with cardiac artery disease, a myocardial perfusion scan, which is a non-invasive method, is utilized. This study is conducted to develop an advantageous software applicable to quantitative myocardial SPECT perfusion. Material and Methods: Each cross-section of the left ventricle was segmented by applying a fuzzy clustering method. After obtaining the myocardial skelet...

1 ABSTRACT Velocity Magnetic Resonance (MR) images are a novel form of medical images. A special gradient-modulation technique is utilised to capture motion velocity of tissue and blood. As well as the tissue density image, there are also other images that depict the velocity components along axes deened relative to the plane of imaging. The images are of the cardiac region and are aligned with...

In this paper, we propose the least-squares method for computing the positive solution of a $mtimes n$ fully fuzzy linear system (FFLS) of equations, where $m > n$, based on Kaffman's arithmetic operations on fuzzy numbers that introduced in [18]. First, we consider all elements of coefficient matrix are non-negative or non-positive. Also, we obtain 1-cut of the fuzzy number vector solution of ...

Abstract In this paper, we introduce the concepts of $$(\in ,\in \vee (\kappa ^*,q_\kappa ))$$ ( ∈ , ∨ κ ∗ q ) -fuzzy left...

Segmentation is generally regarded as partitioning space at the boundary of an object so as to represent the object's shape, pose, size, and topology. Some images, however, contain so much noise that distinct boundaries are not forthcoming even after the object has been identified. We have used statistical methods based on medial features in Real Time 3D echocardiography to locate the left vent...

A fuzzy logic controller for a rotary, turbodynamic left ventricular assist system was developed to optimize the delivery of blood flow without inducing suction in the ventricle. The controller is based on the pulsatility in blood flow through the pump and assumes that the natural heart is still able to produce some pumping action. To avoid the use of flow transducers, which are not reliable fo...

Is government ideology important for fiscal policy? I study this question with data from all German States over the period 1975-2005. To identify the effect of ideology, I rely on a fuzzy regression discontinuity design. I find that left-wing state governments spend more than state governments with right-wing and mixed ideology. Deficits of left-wing governments are larger than those of right-w...

In this paper, we propose a new method to obtain the eigenvalues and fuzzy triangular eigenvectors of matrix $$\left( {\tilde{A}} \right)$$ , where elements are given. For purpose, solve 1-cut eigenvectors. Considering interval system $$\left[ \right]_{\alpha } \left[ {\tilde{X}} = {\tilde{\lambda }} 0 \le \alpha 1$$ as α-cut $$\tilde{A}\tilde{X} \tilde{\lambda }\tilde{X}$$ determine left right...
