Internal kink instabilities exhibiting fishbone like behaviour have been observed in a variety of experiments where a high energy electron population, generated by strong auxiliary heating and/or current drive systems, was present. The results of global, self-consistent, non-linear hybrid MHD-Gyrokinetic simulations will be presented. Linear dynamics analysis will enlighten the effect of consid...

[1] This paper presents a satellite-based retrieval method for inferring the vertical variation of cloud droplet effective radius (DER) by utilizing multispectral near-infrared (NIR) measurements at 1.25, 1.65, 2.15, and 3.75 mm, available from the Moderate Resolution Imaging Spectrometer (MODIS) satellite observations. The method is based on the principle that these multispectral NIR measureme...

Background and purpose:Intradialytic hypotension (IDH) is the most frequent complicationin patients receiving haemodialysis (HD) that poses most problems for patient and treatment team. The use of sodiumprofile and ultra filtration (UF) profile is one of the preventive methods that have been recently introduced. However, increased intradialytic weight gain (IDWG) has been described as the sid...

در این پایان نامه روشی برای تطبیق مدل زبانی ارائه شده است. این روش، برمبنای ترکیب الگوریتم کاهش بعد locally linear embedding و مدل زبانی n-gram عمل میکند. الگوریتم locally linear embedding در کاهش ابعاد ساختار داده اصلی را حفظ مینماید. لذا انتظار داریم ساختار کلی ماتریس سند-کلمه در این کاهش بعد دچار خدشه زیاد نگردد. الگوریتم ارائه شده، با استفاده از زبان c++ و بهره گیری از توابع موجود در ابزاره...

In the present study, an analytical investigation on the entropy generation examination for viscoelastic fluid flow involving inclined magnetic field and non-linear thermal radiation aspects with the heat source and sink over a stretching sheet has been done. The boundary layer governing partial differential equations were converted in terms of appropriate similarity transformations to non-line...

In many manufacturing processes, the quality of a product is characterized by a non-linear relationship between a dependent variable and one or more independent variables. Using nonlinear regression for monitoring nonlinear profiles have been proposed in the literature of profile monitoring which is faced with two problems 1) the distribution of regression coefficients in small samples is unkno...

Some quality characteristics are well defined when treated as response variables and are related to some independent variables. This relationship is called a profile. Parametric models, such as linear models, may be used to model profiles. However, in practical applications due to the complexity of many processes it is not usually possible to model a process using parametric models.In these cas...
