The satellite mission GRACE (Gravity Recovery and Climate Experiment) provides monthly solutions of the global gravity field of the Earth. Temporal variations in gravity reflect mass redistributions over the Earth. Those mass movements are caused by physical phenomena such as ice sheet dynamics, accumulation of hydrological masses over land, the dynamics in the solid Earth and the dynamics in t...

BACKGROUND The Thrombolysis in Myocardial Infarction (TIMI) risk scores for Unstable Angina/Non-ST-elevation myocardial infarction (UA/NSTEMI) and ST-elevation myocardial infarction (STEMI) and the Global Registry of Acute Coronary Events (GRACE) risk scores for in-hospital and 6-month mortality are established tools for assessing risk in Acute Coronary Syndrome (ACS) patients. The objective of...

The analysis of EEG signals plays a vital role in the detection of Seizure. The EEG signal of a normal person varies when compared to that of a seizure affected person. A new wavelet is created which closely represents a normal EEG wave. The discrete wavelet transform using the new wavelet family is applied to the input EEG signals. Since the new wavelet represents the normal EEG wave pattern t...

Observations from the Gravity Recovery and Climate Experiment (GRACE) GRACE Follow-On (GRACE-FO) missions can be used to estimate gravimetric excitation of polar motion (PM), which reflects contribution mass changes in continental hydrosphere cryosphere PM variation. Many solutions for Earth’s gravity field variations have been developed by institutes around world based on GRACE/GRACE-FO data; ...

In this paper we critically analyze the so far performed and proposed tests for measuring the general relativistic Lense-Thirring effect in the gravitational field of the Earth with some of the existing accurately tracked artificial satellites. The impact of the 2nd generation GRACE-only EIGEN-GRACE02S Earth gravity model and of the 1st CHAMP+GRACE+terrestrial gravity combined EIGEN-CG01C Earth...

عصمت انبیاء - علیهم السّلام- از جمله مسائل مهمّ و مطرح در ادیان الهی است، و در دین اسلام، وام دار قرآن کریم و سخنان پیامبر اسلام (ص) و ائمّه ی اطهار (ع) می باشد. عصمت، یک نیروی درونی یا به عبارت دیگر ملکه ی نفسانی است که انسان را از اشتباه و گناه حفظ می کند، با وجود این که بر آن قدرت دارد. شیخ مفید و علّامه طباطبایی از جمله کسانی هستند، که در مسئله ی عصمت پیامبران صاحب نظرند، و در تألیفات متعدّد خو...

A new functional model is proposed for gravity field modeling on the basis of KBR data from the GRACE satellite mission. This functional model explicitly connects a linear combination of gravitational potential gradients with a linear combination of range-rate measurements at several successive epochs. The system of observation equations is solved in the least-squares sense by means of the pre-...
