The auditory brainstem response (ABR) has become a routine clinical tool for hearing and neurological assessment. In order to pick out the ABR from the background EEG activity that obscures it, stimulus-synchronized averaging of many repeated trials is necessary, typically requiring up to 2000 repetitions. This number of repetitions can be very difficult,(More)
OSI is an open access system interconnection reference model, is a very good agreement defined protocol specifications. OSI model has seven layers; each layer can have several sub-layers. According to the comparison of OSI and TCP/IP, and research based on the OSI model implementation models and protocols of the Internet, and the OSI model of data(More)
3D reconstruction based on multi-view is a hot research topic in computer vision due to more information and wide scope of the view of multiple views. Feature detection and matching, fundamental matrix estimation, camera self-calibration, 3D reconstruction and dense surface reconstruction are key proportions of 3D reconstruction. This paper summarizes the(More)
In the anion of the title molecular salt, C(6)H(9)BNO(2) (+)·C(7)H(4)NO(4) (-), the dihedral angles between the -COO(2-) and -CO(2)H groups and their attached ring are 4.02 (13) and 21.41 (10)°, respectively. The B atom in the cation adopts a syn-syn geometry and the dihedral angle between the -B(OH)(2) group and its attached ring is 11.06 (5)°. In the(More)
In the title mol-ecule, C(12)H(10)N(2)O(2), the benzene and pyridine rings form a dihedral angle of 5.01 (8)°. The amide group is twisted by 33.54 (7)° from the plane of the pyridine ring. In the crystal, mol-ecules are linked into centrosymmetric dimers via pairs of O-H⋯N hydrogen bonds. N-H⋯O hydrogen bonds further link dimers related into chains along(More)
In the title compound, K(3)[Cu(C(10)H(12)N(2)O(10)P)]·2H(2)O, the Cu(II) ion, one potassium cation and a P atom are situated on a twofold rotation axis. The Cu(II) ion is coordinated by two N and four O atoms from one bis-{[bis-(carboxyl-atometh-yl)amino]-meth-yl}phosphinate ligand in a distorted octa-hedral coordination geometry. The two(More)
In the title compound, C 20 H 22 N 2 O 2 , the cyclohexane ring adopts a chair conformation and the two N atoms bonded to salicylidene groups are in cis positions. Both hydroxy groups are involved in intramolecular O—HÁ Á ÁN hydrogen bonding and the two benzene rings form a dihedral angle of 60.5 (1). Related literature For the crystal structure of(More)
The asymmetric unit of the title co-crystal, C(20)H(16)N(2)·C(18)H(20)O(2), contains one mol-ecule of 4,4'-(cyclo-hexane-1,1-di-yl)diphenol (in which the cyclo-hexane ring adopts a chair conformation) and one mol-ecule of 1-benzyl-2-phenyl-1H-benzimidazole, which are paired through an O-H⋯N hydrogen bond. These pairs are further linked by inter-molecular(More)
