Substituent and Transition Metal Effects on Halogen Bonding: CSD Search and Theoretical Study

Computational and Theoretical Chemistry, 2014
Abstract According to our survey of the Cambridge Structural Database (CSD), a large number of X-ray crystal structures containing C–X⋯NCC/C–X⋯NCM halogen bonds were extracted. In this work, DFT/M06 calculations have been carried out to investigate the influence of substituents and transition metals on halogen bonding.

Interplay Between Halogen Bonds and π–π Stacking Interactions: CSD Search and Theoretical Study

Physical Chemistry Chemical Physics, 2012
According to our survey of the Cambridge Structural Database (CSD), a great number of crystal structures, in which halogen bonds and aromatic stacking interactions are present and play an important role in crystal packing, have been extracted. In this work, ab initio calculations at the MP2 level of theory were performed to investigate the mutual ...

Weak Energetic Effects Between X–π and X–N Halogen Bonds: CSD Search and Theoretical Study

Chemical Physics Letters, 2013
Abstract MP2 and M05-2x calculations have been carried out to investigate the interplay between X–π and X–N halogen bonds. Weak cooperative or diminutive effects are observed in the complexes where the two interactions coexist. For comparison, the mutual influence between H–π interactions and halogen bonds was also examined and the same energetic ...

Verification of search process in CSD coefficient FIR filter design

2016 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS), 2016
In this research, several design methods of FIR (Finite Impulse Response) filters with CSD (Canonic Signed Digit) coefficient are compared to investigate a search process of each method. The design problem is formulated as a 1, 0, −1 combinatorial optimization problem.

Search process in metaheuristics for CSD coefficient FIR filter design

2016 Asia-Pacific Signal and Information Processing Association Annual Summit and Conference (APSIPA), 2016
In this paper, several design methods of CSD (Canonic Signed Digit) coefficient FIR (Finite Impulse Response) filters are compared to investigate a search process of each method. The design problem is formulated as a combinatorial optimization problem.
