Most baryonic matter in the universe exists gaseous form and can be found structures such as galactic halos low-density intergalactic medium. proposed-ray spectroscopy missions Athena, Arcus, Lynx will have capability to identify absorption lines spectra toward bright active nuclei (AGNs), which used a tool probe this missing matter. In study, we examine optical fields surrounding 15 primary ob...

In this work, the design and fabrication process of a stripline 90 degree hybrid coupler using LTCC technology are presented. The main specifications required for the device developed were 1.03 GHz central operation frequency, isolation higher than 23dB and a maximum size of 15 mm x 10 mm. To obtain a starting point of physical parameters for the simplified DC configuration a transmission lines...

We report an extremely rare case of Turner syndrome mosaicism in a 30-year-old woman. At least 100 metaphases were observed and analyzed through GTG banding with over 550 band resolutions observed. G-banded chromosome analysis revealed a mosaic female karyotype involving 3 different cell lines. One cell line (90% of the analyzed metaphases) presented monosomy X, while 6% of the cells showed tri...

Three new Complexes of formula [pd(bpy)(R-NH-CSS)] Cl (where bpy is 2/2′- bipyridine, and R-NH-CSS is butylamine, hexylamine- and octyamine-dithiocabamate anion) have been synthesized by University of Sistan and Blachostan. These complexes have been characterized by spectroscopic methods such as ultraviolet-visible, infrared and 1H-NMR as well as conductivity measurements and chemical analysis....

the principle of dimensionality reduction with pca is the representation of the dataset ‘x’in terms of eigenvectors ei ∈ rn  of its covariance matrix. the eigenvectors oriented in the direction with the maximum variance of x in rn carry the most      relevant information of x. these eigenvectors are called principal components [8]. assume that n images in a set are originally represented in mat...

Congestion and overloading for lines are the main problems in the exploitation of power grids. The consequences of these problems in deregulated systems can be mentioned as sudden jumps in prices in some parts of the power system, lead to an increase in market power and reduction of competition in it. FACTS devices are efficient, powerful and economical tools in controlling power flows through ...
