Improved characterization of HRV signals based on instantaneous frequency features estimated from quadratic time-frequency distributions with data-adapted kernels
(
Elsevier Ltd
, 2014 , Article)
The analysis of heart rate variability (HRV) provides a non-invasive tool for assessing the autonomic regulation of cardiovascular system. Quadratic time-frequency distributions (TFDs) have been used to account for the ...
A review of time-frequency matched filter design with application to seizure detection in multichannel newborn EEG
(
Elsevier Inc.
, 2014 , Article)
This paper presents a novel design of a time-frequency (t-f) matched filter as a solution to the problem of detecting a non-stationary signal in the presence of additive noise, for application to the detection of newborn ...
Multicomponent noisy signal adaptive instantaneous frequency estimation using components time support information
(
Institution of Engineering and Technology
, 2014 , Article)
This study proposes an adaptive method for components instantaneous frequency (IF) estimation of noisy non-stationary multicomponent signals, combined with the components time-support estimation method based on the shorttime ...
Bayesian inference for Pr ( Y<X ) in the exponential distribution based on records
(
Elsevier
, 2014 , Article)
We consider Bayesian estimation of the stress–strength reliability based on record values. The estimators are derived under the squared error loss function in the one parameter as well as two-parameter exponential ...
Computation of Yvon-Villarceau circles on Dupin cyclides and construction of circular edge right triangles on tori and Dupin cyclides
(
Elsevier Ltd
, 2014 , Article)
Ring Dupin cyclides are non-spherical algebraic surfaces of degree four that can be defined as the image by inversion of a ring torus. They are interesting in geometric modeling because: (1) they have several families of ...
إيران واتفاق جنيف: تجديد للشرعية أم استجابة لتحدّ مرحلي؟
(
المركز العربي للأبحاث ودراسة السياسات
, 2014 , Article)
تستند هذه الدراسة إلى فرضية مفادها أنّ النظام السياسي الإيراني ممثلاً بمؤسسة الحكم، قد قرّر المضيَّ في توقيع اتفاق جنيف بوصفه جزءًا من سلوك النظام المتواتر من أجل تجديد شرعيته داخليًّا. وترى الدراسة أنّ توقيع الاتفاق جاء ...
ایران و نظرية : جدولة الخصوم
(2014 , Article)
لم تثر دولة في علاقاتها وتحالفاتها في الشرق الأوسط المعاصر مثل جمهورية ايران الاسلامية. فالنظام السياسي الذي بدا بخطاب ثوري غير متسامح مع كل قوى الاستكبار والمتحالفين معها معلنا ان شرعيته في الداخل والخارج مستمدة من مساندة ...

, 2014 , Article)
This article focuses on analysing political culture for understanding the dynamics of ideological rivalry in the Middle East. It reviews the concept of political culture and locates, therein, constant references to the ...
Islam, the West and ‘Man’ in the State of Nature
(
German Orient-Institute
, 2014 , Article)
What is the natural condition of human beings in the state of nature? What are the circumstances that exist in the state of nature and what may one, convincingly, claim in regards to human nature? Or, better still, how do ...
Ni-P-TiO2 Composite coatings on copper produced by sol-enhanced electroplating
(
Electrochemical Science Group
, 2014 , Article)
Ni-P-TiO2 composite coatings were prepared on copper substrate by TiO2 sol-enhanced electroplating. A systematic study of Ni-P-X coatings with different sol concentrations (TiO2 concentration X from 0 to 50 mL/L) has been ...
