Reconstruction of an Inductive Velocity Field Vector from Doppler Motions and a Pair of Solar Vector Magnetograms
We outline a general methodology to infer the inductive velocity field vector in solar active regions. For the first time, both the field-aligned and the crossfield velocity components are reconstructed. The cross-field velocity solution accounts for the changes of the vertical magnetic field seen between a pair of successive active-region vector magnetograms via the ideal induction equation. T...
متن کاملEchocardiographic Assessment of Left Ventricle Torsion by Tissue Doppler and Velocity Vector Imaging
Introduction Left ventricular (LV) twist is believed to store potential energy and plays an important role in generating diastolic suction. Recent advances in echocardiography techniques have allowed quantification of LV twist. The aim of the present study was to compare LV twist and torsion in healthy human subjects determined by velocity vector imaging (VVI) and tissue Doppler imaging (TDI) a...
متن کاملthe aesthetic dimension of howard barkers art: a frankfurtian approach to scenes from an execution and no end of blame
رابطه ی میانِ هنر و شرایطِ اجتماعیِ زایش آن همواره در طولِ تاریخ دغدغه ی ذهنی و دل مشغولیِ اساسیِ منتقدان و نیز هنرمندان بوده است. از آنجا که هنر در قفس آهنیِ زندگیِ اجتماعی محبوس است، گسترش وابستگیِ آن با نهاد ها و اصولِ اجتماعی پیرامون، صرفِ نظر از هم سو بودن و یا غیرِ هم سو بودنِ آن نهاد ها، امری اجتناب ناپذیر به نظر می رسد. با این وجود پدیدار گشتنِ چنین مباحثِ حائز اهمییتی در میان منتقدین، با ظهورِ مکتب ما...
Reconstruction of Vector Fields using Doppler Tomography
In ordinary tomography the objective is to reconstruct a scalar function f from all its line integrals. The question dealt with in this paper is if it is possible to do the same for a vector valued function, when we know the line integrals of f dl, where l is the directional vectors of the lines. The answer is that it is only possible to regain r f. Some simulations and experiments done in asso...
متن کاملConstruction of a Synthetic Vector for Preparation of a 100 Base Pair DNA Ladder
DNA size markers are widely used to estimate the size of DNA samples on agarose or polyacrylamide gelelectrophoresis (PAGE). DNA markers can be prepared by mixing PCR products with definite sizes.Alternatively, they are prepared by restriction enzyme digestion of the genomic DNA of bacteriophages ornatural and synthetic DNA plasmids. The present study describes engineering of ...
