Imperialist competitive algorithm (ICA) is a new socio-politically motivated global search strategy. The ICA is applied to hybrid composite laminates to obtain minimum weight and cost. The approach which is chosen for conducting the multi-objective optimization was the weighted sum method (WSM). The hybrid composite Laminates are made of glass/epoxy and carbon/epoxy to combine the lightness and...
We present the new LICAD algorithm to solve the permutation problem of the ICA in the frequency domain and improve the separation quality. In the proposed algorithm, first, the sources' angles are estimated in each frequency bin using an ICA separating matrix. Then, these estimates are compared to the true values obtained from a pre-processing stage. If the difference among similar angles is le...
Optimization of turning process is a non-linear optimization with constrains and it is difficult for the conventional optimization algorithms to solve this problem. The purpose of present study is to demonstrate the potential of Imperialist Competitive Algorithm (ICA) for optimization of multipass turning process. This algorithm is inspired by competition mechanism among imperialists and coloni...
با توجه به ضرورت تشخیص ارقام مختلف سیب¬زمینی، استفاده از فناوری¬های نوین مطابق با علم روز دنیا ضروری می باشد. از جمله روش های جدید برای تشخیص واریته محصولات کشاورزی استفاده از تکنیک پردازش تصویر در تلفیق با هوش محاسباتی می¬باشد. در این تحقیق به منظور تشخیص ارقام مختلف سیب¬زمینی، سه روش هوش مصنوعی شامل شبکه عصبی مصنوعی (ann)، الگوریتم رقابت استعماری ica))، و سستم استنتاج عصبی- فازی (anfis) و 2 ر...
PURPOSE The SYNTAX Score (SS) has an important role in grading the complexity of coronary artery disease (CAD) in patients undergoing revascularization. Noninvasive determination of SS prior to invasive coronary angiography (ICA) might optimize patient management. We aimed to evaluate the agreement between ICA and multidetector computed tomography (MDCT) while testing the diagnostic effectivene...
Cell culture studies demonstrate an increase in cardiac L-type Ca2+ current (ICa,L) density on sympathetic innervation in vitro and suggest the effect depends on neurally released neuropeptide Y (NPY). To determine if a similar mechanism contributes to the postnatal increase in ICa,L in vivo, we prepared isolated ventricular myocytes from neonatal and adult mice with targeted deletion of the NP...
Independent Component Analysis (ICA) is a technique that attempts to separate data into maximally independent groups. Achieving maximal independence in space or time yields two varieties of ICA meaningful for functional MRI (fMRI) applications: spatial-ICA (SICA) and temporal-ICA (TICA). SICA has so far dominated the application of ICA to fMRI. The objective of these experiments was to study IC...
INTRODUCTION Ionized calcium (iCa) concentration is often used in critical care and measured using blood gas analyzers at the point of care. Controlling and adjusting regional citrate anticoagulation (RCA) for continuous renal replacement therapy (CRRT) involves measuring the iCa concentration in two samples: systemic with physiological iCa concentrations and post filter samples with very low i...
Dimensional reduction methods have significantly improved the simplification of Pulsed Thermography (PT) data while improving accuracy results. Such approaches reduce quantity to analyze and improve contrast main defects in samples contributed their popularity. Many works been proposed literature mainly based on Principal Component (PCT). Recently Independent Analysis (ICA) has a topic attentio...
Recently, we showed that both acute metabolic acidosis and respiratory acidosis stimulate parathyroid hormone (PTH) secretion in the dog. To evaluate the specific effect of acidosis, ionized calcium (iCa) was clamped at a normal value. Because iCa values normally increase during acute acidosis, we now have studied the PTH response to acute metabolic and respiratory acidosis in dogs in which the...
