این پژوهش با الهام گرفتن از نتایج یک طرح مطالعاتی کاربردی، رویکرد سلسلهمراتبی جهت پیگیری فرایند توسعه تأمینکنندگان و حمایت تصمیمات موجود در هر مراحل آن ارائه میکند. ابتدا، زمینههای تأمین نیازمند سپس واجد شرایط هریک زمینهها به کمک تصمیمگیری چندشاخصه بهترین-بدترین مشخص میگردند. معیارهای شناسایی نیز مرور مطالعات پیشین بهرهگیری نظرات خبرگان حوزهی خرید استخراجشدهاند. درنهایت، مدل ریاضی ...
UNLABELLED BACKGROUND The corrosion inhibition performance of pyrazolylindolenine compounds, namely 4-(3,3-dimethyl-3H-indol-2-yl)-pyrazole-1-carbothioamide (InPzTAm), 4-(3,3-dimethyl-3H-indol-2-yl)-1H-pyrazole-1-carbothiohydrazide (InPzTH) and 3,3-dimethyl-2-(1-phenyl-1H-pyrazol-4-yl)-3H-indole (InPzPh),) on copper in 1M HCl solution is investigated by electrochemical impedance spectroscopy...
We describe the participation of the Saarland University LSV group in the DARPA/NIST TREC 2007 Q&A track with the Alyssa system, using an approach that combines cascaded language-model based information retrieval (LMIR) with data-driven learning methods for answer extraction and ranking. To test the robustness of this approach that was previously proven on news data also across document collect...
A detection system based on a multiplex reverse transcription (RT) polymerase chain reaction (PCR) was developed to simultaneously identify multiple viruses in the lily plant. The most common viruses infecting lily plants are the cucumber mosaic virus (CMV), lily mottle virus (LMoV), lily symptomless virus (LSV). Leaf samples were collected at lily-cultivation facilities located in the Kangwon ...
In this study, simple, fast and reliable cyclic voltammetry (CV), linear sweep voltammetry (LSV), square wave voltammetry (SWV) and differential pulse voltammetry (DPV) methods were developed and validated for determination of bosentan in pharmaceutical preparations. The proposed methods were based on electrochemical oxidation of bosentan at platinum electrode in acetonitrile solution containin...
The first structures were proto-voids formed in the primordial plasma when viscous and weak turbulence forces balanced gravitational forces at the scale of causal connection LH ≡ ct ≈ LSV ≡ (γν/ρG) 1/2 ≈ LST ≡ ε /(ρG) at time t ≈ 30 000 years (10 s) the age of the universe, with c the speed of light, γ ≈ 1/t the rate of strain, ν the kinematic viscosity, and LSV and LST Gibson’s 1996 viscous an...
The first structures were proto-voids formed in the primordial plasma. Viscous and weak turbulence forces balanced gravitational forces when the scale of causal connection LH ≡ ct ≈ LSV ≡ (γν/ρG) 1/2 ≈ LST ≡ ε /(ρG) at time t ≈ 30,000 years (10 s), with c the speed of light, γ ≈ 1/t the rate of strain, and ν the kinematic viscosity, where LSV and LST are viscous and turbulent Schwarz scales of ...
Aim: The study aimed to evaluate the normal liver stiffness value (LSV) with shear wave elastography (SWE) in children and adults, reveal relationship between LSV age, gender, body mass index (BMI), size. Material Methods: A total of 173 healthy volunteers, 92 female 81 male, aged 4 50 years were included this study. measurements performed supine position during breathing from right intercostal...
در این پژوهش با استفاده از دادههای آماری ماهانۀ 24 شرکت سرمایهگذاری و با بهکارگیری مدل لاکونیشوک (1992) طی دورۀ زمانی 1394- 1388، تأثیر رفتار تودهواری بر عملکرد این شرکتها بر اساس نظریههای مدرن و فرامدرن پرتفوی بررسی شده است. برای این منظور، ابتدا متغیرهای پژوهش از لحاظ مانایی بررسی شدند، سپس از روش حداقل مربعات تعمیمیافتۀ برآوردی (EGLS) و گشتاور تعمیمیافته (GMM) برای تجزیه و تحلیل دا...
