Local Government Engineering Department (LGED) is an organ of Bangladesh government created for provision of transport infrastructures in rural areas and to provide technical support to the rural and the urban local government institutions (LGIs), planning and implementation of infrastructure development projects in the rural and urban areas to improve communication and transport network, job ...
X-ray magnetic circular dichroism ( XMCD) is a difference spectrum of two X-ray absorption spectra (XAS) taken in a magnetic field, one taken with left circularly polarized light, and one with right circularly polarized light. [1] By closely analyzing the difference in the XMCD spectrum, information can be obtained on the magnetic properties of ...
In electronics, an LED circuit or LED driver is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED. The voltage drop across an LED is approximately constant over a wide range of operating ...
Circular reasoning ( Latin: circulus in probando, "circle in proving"; [1] also known as circular logic) is a logical fallacy in which the reasoner begins with what they are trying to end with. [2] Circular reasoning is not a formal logical fallacy, but a pragmatic defect in an argument whereby the premises are just as much in need of proof or ...
Chittagong ( / ˈtʃɪtəɡɒŋ / CHIT-ə-gong ), [7] officially Chattogram [8] ( Bengali: চট্টগ্রাম, romanized : Côṭṭôgrām [ˈtʃɔʈːoɡram], Chittagonian: চাটগাঁও romanized: Sāṭgão ), is the second-largest city in Bangladesh. Home to the Port of Chittagong, it is the busiest port in Bangladesh and ...
Circular dichroism is the difference . [5] The electric field of a light beam causes a linear displacement of charge when interacting with a molecule ( electric dipole ), whereas its magnetic field causes a circulation of charge ( magnetic dipole ). These two motions combined cause an excitation of an electron in a helical motion, which ...
Circular dichroism (CD) is the differential absorption of left- and right-handed circularly polarized light. Circular dichroism is the basis of a form of spectroscopy that can be used to determine the optical isomerism and secondary structure of molecules. In general, this phenomenon will be exhibited in absorption bands of any optically active ...
Directional statistics (also circular statistics or spherical statistics) is the subdiscipline of statistics that deals with directions ( unit vectors in Euclidean space, Rn ), axes ( lines through the origin in Rn) or rotations in Rn. More generally, directional statistics deals with observations on compact Riemannian manifolds including the ...
