Abstract: We consider three level difference replacements of parabolic equations focusing on the heat equation in two space dimensions. Through a judicious splitting of the approximation, the scheme qualifies as an alternating direction implicit (ADI) method. Using the well known fact of the parabolic-elliptic correspondence, we shall derive a two stage iterative procedure employing a fractiona...

With the rise in multimedia content over years, more variety is observed recording environments of audio. An audio processing system might benefit when it has a module to identify acoustic domain at its front-end. In this paper, we demonstrate idea identification (ADI) for speaker diarization. For this, first present detailed study various domains third DIHARD challenge highlighting factors tha...

Angular differential imaging (ADI) and spectral (SDI) are commonly used for direct detection characterisation of young, Jovian exoplanets in datasets obtained with the SPHERE/IFS instrument. We compare performance ADI, SDI, three combinations ADI SDI to find which technique achieves highest signal-to-noise ratio (S/N), we analyse their as functions integration time, field rotation, wavelength r...

Recent studies demonstrate increasing rates of severe maternal morbidity (SMM) as well disproportionate frequencies amongst racial minorities, with black women consistently having the highest proportion SMM. Area deprivation index (ADI), a nationally used composite measure neighborhood socioeconomic disadvantage, is associated multimorbidity including adverse pregnancy outcomes. We sought to ex...

Soundscape analysis, using acoustic indices, provides researchers with valuable ecological information to assess biodiversity, species behavior, and noise pollution. In this study,  to analyze biophonies and anthrophony in six urban parks in  Isfahan city in spring, six acoustic indices, including Acoustic complexity index (ACI), Acoustic Diversity Index (ADI), Acoustic Evenness Index (AEI), an...

The current study was undertaken to investigate the dynamic characteristics of tomato crop, such as its plant height and leaf area index (LAI), based on effective cumulative temperature. This assessed under aerated drip irrigation (ADI) conditions application a specific nitrogen (N) dose, their relationship with yield crop formulated. conducted in greenhouse located Zhengzhou, Henan province, C...

در این مقاله تأثیر پارامترهای ورودی (سرعت برشی و سرعت پیشروی) بر پارامترهای خروجی (انرژی ویژه تراش و زبری سطح) در فرآیند ماشین­کاری چدن adi و فولاد آلیاژی پایه کرم  42crmo4مورد مطالعه قرار گرفته و قابلیت ماشین کاری آن ها با یک دیگر مقایسه شده است. بر اساس نتایج بدست آمده مشخص گردید که انرژی ویژه تراش در ماشین کاری چدن adi بیش تر از فولاد 42crmo4 می باشد و با افزایش سرعت برشی در هر دو نمونه، انر...
