Lubrication with ambient air is not quite generally applied. The best known application is the “foil bearing” in tape recording systems for audio, video and computer applications; where the gap height that is needed for effective lubrication may quite easily be attained. This air gap reduces tape friction and wear of tape and recording head substantially. On the other hand, though, the air gap ...

In this paper, experimentally derived correlations of heat transfer and pressure drop are used in a Pareto based Multi-Objective Optimization (MOO) approach to find the best possible combinations of heat transfer and pressure drop of TiO2-water nanofluid flow in tubes fitted with multiple twisted tape inserts in different arrangement. In this study there are four independent design variables: t...

The friction coefficient between a guide and a tape sample is determined experimentally as a function of nominal tension, speed and guide radius. A comparative study between metal particulate and metal evaporated tape is performed. The tape/guide contact pressure correlated to the experimental results. Tape temperature measurements are compared with the experimentally obtained friction coeffici...

A theory of one-tape linear-time Turing machines is quite different from its polynomial-time counterpart since one-tape linear-time Turing machines are closely related to finite state automata. This paper discusses structural-complexity issues of one-tape Turing machines of various types (deterministic, nondeterministic, reversible, alternating, probabilistic, counting, and quantum Turing machi...

We examine the power of quantum Turing machines (QTM’s) which compute string-valued functions of their inputs using small workspace. A (probabilistic or quantum) Turing machine has three tapes: A read-only input tape, a read/write work tape, and a “1.5-way" write-only output tape. Consider a partial function f : Σ 1 → Σ 2 , where Σ1 and Σ2 are the input and output tape alphabets, respectively. ...

The paper presents analytical studies of the torque motor tape active element. The tape active element is a novel type of a motor's stator organization, where the conventional winding is replaced by a tape winding. Given the operation principle of proposed active element; its torque characteristics are then computationally found with using the finite element method (FEM). The results show the p...

BACKGROUND The aim of the present study was to assess the efficacy of kinesiotherapy used for treating various disorders in athletes on pain and pedal functions in patients with calcaneal apophysitis. METHODS This prospective randomized controlled study included 22 patients with calcaneal apophysitis aged 8 to 16 years presenting with heel pain among junior athletes of a professional football...

1. Discoloration of polyvinyl chloride (PVC) tape has been used in peatland ecological and hydrological studies as an inexpensive way to monitor changes in water-table depth and reducing conditions. 2. We investigated the relationship between depth of PVC tape discoloration and measured water-table depth at monthly time steps during the growing season within nine kettle peatlands of northern Wi...

INTRODUCTION Lip tape therapy or lip taping is a widely used tissue approximation technique in cleft lip babies. Vari ous tapes have been tested and used worldwide. Allergic reactions and skin irritation are the most common problems encountered. Tension force across the tape cannot be consistently applied. Cost is also an obstacle to adopting lip tape therapy, particularly in developing countri...
