A thin-film optical filter used as a one-dimensional spatial filter is presented, and its design is briefly examined. The filter consists of a stack of quarter-wave dielectric layers upon a right-angle prism that selectively cancel a reflected or transmitted plane-wave front for various angles of incidence. Transmittance and reflectance are low-pass functions or high-pass functions of the angle...

In the title compound, C12H9NO3, the benzoate and furan rings are almost coplanar, making a dihedral angle of 11.68 (9)°. The twist angle between the -COO group and the benzene ring is only 2.79 (16)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming chains along [100]. The mol-ecules stack in a herringbone fashion and inversion-related chains are linked by offset π-π inte...

The complete mol-ecule of the title compound, C(18)H(22)N(4)O(6), is generated by the application of a twofold axis of symmetry. Twists are evident in the mol-ecule, i.e. between each -C=N-N group and the adjacent oxazole ring [dihedral angle = 46.08 (12) °] and between the latter and attached ester group [excluding the terminal methyl group; dihedral angle = 24.4 (7) °]. In the crystal, C-H⋯O ...

In the title mol-ecule, C(14)H(9)N(3)O(3), the dihedral angle between the quinoxaline and benzene rings is 77.13 (9)°. The mol-ecule is twisted about the ether-benzene O-C bond, with a C-O-C-C torsion angle of -102.8 (2)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming layers in the ab plane, with one nitro O atom accepting two such inter-actions. The layers stack along ...

The title compound, C29H24N2OS, contains a pheno-thia-zine moiety linked to a planar carbazole unit (r.m.s. deviation = 0.029 Å) by a C-C single bond. The pheno-thia-zine moiety possesses a typical non-planar butterfly structure with a fold angle of 27.36 (9)° between the two benzene rings. The dihedral angle between the mean planes of the carbazole and pheno-thia-zine units is 27.28 (5)°. In t...

In this paper Two Hybrid digital circuit design techniques are produced as Hybrid MultiThreshold CMOS complete stack technique and Hybrid Multi-Threshold CMOS partial stack technique for reducing the leakage power dissipation in mode transistion.Tri-modal switch are performance depends on these two techniques reduce the leakage power dissipation. These technique are implemented in the CADENCE v...

Although sequence-to-sequence (seq2seq) network has achieved significant success in many NLP tasks such as machine translation and text summarization, simply applying this approach to transition-based dependency parsing cannot yield a comparable performance gain as in other stateof-the-art methods, such as stack-LSTM and head selection. In this paper, we propose a stack-based multi-layer attent...

In this paper we propose a generalization of the Stack-based decoding paradigm for Statistical Machine Translation. The well known single and multi-stack decoding algorithms defined in the literature have been integrated within a new formalism which also defines a new family of stackbased decoders. These decoders allows a tradeoff to be made between the advantages of using only one or multiple ...
