Commercial lead zirconate titanate (PZT) perovskite powders were used to fabricate ceramic tape and then sintered by microwave and conventional methods. Both dielectric and piezoelectric properties of PZT ceramic tapes were studied in terms of sintering process. X-ray diffraction analysis (XRD) and scanning electron microscopy (SEM) show the PZT perovskite phase with smaller grain size and dens...

Enantiopure dipeptide-derived 1,3,5-triazepan-2,6-diones and form H-bonded 3(1) helical molecular tapes with P chirality in the solid state; in the case of , these columnar tapes self-assemble through aromatic-aromatic interactions to give hollow tubular structures.

We study a generalized version of reversal bounded Turing machines where, apart from several tapes on which the number of head reversals is bounded by r(n), there are several further tapes on which head reversals remain unrestricted, but size is bounded by s(n) (where n denotes the input length). Recently [9,10], such machines were introduced as a formalization of a computation model that restr...

UNLABELLED The three-dimensional configuration of mid-urethral sling tapes is difficult to demonstrate in traditional anatomical dissections or imaging studies. The aim of this study was to test the utility of a novel technique using mesh tapes to assess spatial differences between the in-out and out-in transobturator mid-urethral slings. Two independent surgeons performed their usual transobtu...

In the title compound, C6H12O4.H2O, 1,4/2,5-cyclohexanetetrol and water molecules are seen to possess twofold symmetry. All four hydroxyl groups of the tetrol participate in extensive intermolecular O-H...O hydrogen bonding to form molecular tapes propagating along the a axis. Translationally related tapes along the c axis are held together by four coordinated water molecules.

This paper presents a framework for the conversion of audiotape spoken books to full featured digital talking books. It is developed within the context of the IPSOM project. The introduction of search, cross-referencing and annotation mechanisms, with multimedia and trough multimodal capabilities are considered. Different formats and standards are taken into consideration, as well as different ...

We propose a new method of ensuring the redundant storage of information on tertiary storage, especially tape storage. Conventional methods for redundant data storage on tape include mirroring (storing the data twice) and Redundant Arrays of Inexpensive Tapes (RAIT). Mirroring incurs high storage costs, while RAIT is inflexible because special hardware is used and all tapes in a stripe must be ...

The propagation of electrical trees in bent sections of mica tapes is described. The investigations have been made because tapes in coil insulations of high voltage rotating machines cannot always be wound in a perfectly even manner. The tapes are bent at the coil edges, at places where tapes overlap or due to the tapingand manufacturing process. Possible tape bends were therefore analysed by t...
