An exact dispersion relation is obtained for electromagnetic waves propagating on a thin metallic tape helix of arbitrary width, supported by a radially stratified dielectric layer and enclosed by a metallic shell. By expanding the surface currents on the tape in a series of Chebyshev polynomials, the unquantifiable assumptions made in all previously published analyses of the tape helix regardi...

High-Temperature Superconducting (HTS) materials can introduce substantial improvement in signal-to-noise ratio (SNR) of images for small-size sample or low-field MRI system (<1T) [1]. Expensive HTS thin film is typically used for making receiver surface coils for substantial SNR improvements [2]. A 5-inch HTS tape coil using silver-alloy sheathed Bi-2223 tape was first developed [3], which all...

This article describes two practical applications of weighted multi-tape automata (WMTAs) in Natural Language Processing, that demonstrate the augmented descriptive power of WMTAs compared to weighted 1-tape and 2-tape automata. The two examples concern the preservation of intermediate results in transduction cascades and the search for similar words in two languages. As a basis for these appli...

OBJECTIVE To assess the benefits of giving parents tape recorded child development centre assessment report summaries. DESIGN Prospective randomly allocated study. SETTING Child development centre, Birmingham Children's Hospital. SUBJECTS Parents of 113 consecutive children attending for multidisciplinary developmental assessment. OUTCOME MEASURES Recall of information and use of, and v...

Sections 4 and 5 are " bonus " material, not part of the syllabus. These notes do not include the proof of PSPACE-completeness of the TQBF problem, which is well explained in Sipser's book. The problem called PATH in Siper's book is called STCONN here. L.T. A machine solves a problem using space s(·) if, for every input x, the machine outputs the correct answer and uses only the first s(|x|) ce...

Based on the structural and experimental studies of more than 300 insect species from different lineages, we have developed and characterized a bioinspired polymer material with the ability of multiple glue-free bonding and debonding. The material surface is covered with a pattern of microstructures, which resembles the geometry of tenent hairs previously described from the feet of flies, beetl...

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...

Background. Kinesiotape (K-tape) application can attenuate postural malalignment. However, the effects of K-tape on the changes in the respiratory system in postural problems remain unclear. Objectives. This study investigated the effects of 6-week functional correction with the K-tape on the forward shoulder posture (FSP) and respiratory function. Methods. A randomized clinical trial was per...

Recent attention on global environmental changes has stimulated the development of large scale global information systems. Satellite images play a very important role for understanding these global changes, but their data size are very large. Magnetic tape archivers are often used for them because of their capacity, but their capacity cannot be increased except by adding a new archiver which is...
