Využití techniky C2H při implementaci algoritmů pro FPGA
Tato práce se zabývá technikou C2H a jejím využití pří implementaci algoritmů pro FPGA. V rámci práce je implementováno s využitím C2H několik struktur číslicových filtrů FIR a IIR, u kterých je provedeno porovnání z hlediska využitých zdrojů FPGA, maximální frekvence, latence, složitosti …

Quartic Force Fields for Electronically Excited States of Interstellar Molecules
… in a second paper exploring the ethynyl (C2H) radical’s ground X 2Σ+ state and low-lying A 2Π state as well as its anionic form, the acetylide anion (C2H−). Special basis sets designed to treat diffuse (dipole-bound) states are developed in the final chapter which lays the foundation for …

Binuclear Transition Metal Derivatives of 1,2-Bis(indenyl)ethane
… the binuclear compounds Ru2(CO)4(mu-(eta 5-C9H6)2C2H4 and [(eta5-C9H6)C2H 4(C9H7)Ru(CO)2]2. The corresponding reaction in heptane gave instead the tetranuclear cluster [Ru4H(CO) 9(mu3-eta2-eta2-eta 5-C9H6)](C2H4)(C 9H7). The structure of the rac form of Ru 2(CO)4(mu-(eta5-C9H6) 2C2H4 was …

Aromaticity Across States: A Framework for Reactivity and Structure in Organic Systems
… between delocalized D2h and bond-localized C2h forms. By combining computed and experimental proton chemical shifts with modern density functional methods, we show that TtB-s-indacene adopts a bond-localized C2h structure, consistent with its antiaromatic character, and highlight limitations …

Etude par Spectrométrie de Masse de la formation d'Ions Négatifs par Attachement Electronique Dissociatif et par le processus de Paire d'Ions.
… detected. (iii) polyatomic molecules, i.e. CH4, C2H2, C2H4, C2H3F and C2H3Cl. Beside the monoatomic negative ions (H-, C-), diatomic and polyatomic negative ions are detected. For several of these species the electron affinity (EA) of the radical is not known, e.g. CH, C2 and C2H. From the …

A multi-molecular line study of an entire giant molecular cloud
… significant differences among CS, HCO+, HNC and C2H line emissions, suggesting these four molecules are `well-mixed' on large scale, possibly by turbulence. PCA of the integrated emission maps separates molecules into low (13CO and C18O) and high (the rest) density tracers, identifies …

Hall effect in the superconducting and normal states in detwinned and twinned single crystals of zinc-doped YBa2Cu3O7-d
… the Hall conductivity followed the CdH+C2H law. According to the theory of the Hall effect in the mixed state [1], the first term comes from the vortex motion's contribution, and the other term comes from the quasiparticles in the vortex cores. We found that absolute value of the …

Investigation of Structure and Properties of Low Temperature Deposited Diamond-Like Carbon Films
… however, dissociates to an acetylenic ion, C2H-, in liquid ammonia. The electrochemistry heterogeneity also leads to island and two-dimensional (2D) nucleation growth of DLC films. Different bond formations of metal to carbon and different chemisorptions of acetylene on metal play important …

Electrical and magnetic properties of twin-free single-crystal praseodymium-doped YBa2Cu3O7-d
… be expressed as the sum of two terms, CtiH and C2H. C1 and C2 are independent of field, but depend on temperature and Pr concentration. The temperature dependences ofC1 and C2 weaken with increasing Pr concentration up to the disappearance of the sign reversal, at which point C1 changes sign and …

Experimental and theoretical vibrational spectroscopic studies of diketopiperazines
… energy structures of AMDKP (C2) and DMDKP (C2h) have boat and planar conformations, respectively. Due to intermolecular hydrogen bonding with neighbouring molecules it is suggested that in AMDKP, the N-H bonds of the DKP appear at lower wavenumbers (between 3165 cm-1 and 3182 cm-1) compared …
