Mitigating tip vortex cavitation by a flexible trailing thread
Physics of Fluids, 2019 Tip Vortex Cavitation (TVC) is a major issue in design and operation of axial hydraulic machines. We investigate the capacity of a flexible trailing thread in alleviating TVC by analyzing the flow-induced motion. For this purpose, a nylon thread with three diameters is cut in various lengths and attached to the tip of an elliptical hydrofoil.

A New Threaded Flexible Catheter Guide
Journal of Urology, 1982Abstract A new threaded, flexible and reusable catheter guide has been developed, which is compatible with standard filiforms and Councill catheters. It can be used in various situations that involve difficult and complicated strictures, and insertion via a panendoscope. This catheter guide is inexpensive and simple to use.

On the motion of flexible threads in a stokes shear field
Journal of Non-Newtonian Fluid Mechanics, 1983Authors obtained an exact solution for the motion of a flexible, inextensible thread in an unbounded Stokes shear flow by considering the limit of infinitely small lateral/axial mobility ratios. With the aid of this solution permanence and stability have been examined for threads having uniform axial mobility.

Flexible Scheduling and Thread Allocation for Synchronous Parallel Tasks
PARS: Parallel-Algorithmen, -Rechnerstrukturen und -Systemsoftware, 2012We describe a task model and dynamic scheduling and resource allocation mechanism for synchronous parallel tasks to be executed on SPMD-programmed synchronous shared-memory MIMD parallel architectures with uniform, unit-time memory access and strict memory consistency, also known in the literature as PRAMs (Parallel Random Access Machines).

Wearable Flexible Touch Interface Using Smart Threads
2018 IEEE SENSORS, 2018We present an innovative concept for a touch interface made from strain sensing smart threads. The Flexible Touch Interface (FlexTI) is based on assembling strain sensing threads in a 2D matrix assembled directly on skin or as a wearable device.

Trapping and Dynamics of Semi-flexible Threads
Optica Biophotonics Congress 2025We explore a computational, finite-element approach to the study of flexible threads in optical tweezers, illustrating the method with nanowires in Gaussian and Laguerre-Gaussian traps. We also explore optical binding effects.

Calculation of the problem on a rotating flexible thread
Doklady Physics, 2017A solution to the problem of a flexible thread rotating around a horizontal axis is presented. Dependences calculated in elementary functions with graphic applications are obtained for determining the parameters of the rotating thread, such as the thread-shape outline, the largest deviation from the axis, the values of curvature angles, and the thread ...

Supporting flexible safety and sharing in multi-threaded environments
2000There is increasing interest in extensible systems (such as extensible operating systems, mobile code runtime systems, Internet browsers and servers) that allow external programs to be downloaded and executed directly within the system. While appealing from system design and extensibility points of view, extensible systems are vulnerable to aberrant ...

Stationary Shape of a Moving Heavy Flexible Thread
Moscow University Mechanics Bulletin, 2018A model describing the shape of the stationary segment of a heavy flexible inextensible thread moving in a fixed vertical plane down to a given depth from a fixed position to a fixed position is considered. The parametric equations of the stationary curve are derived. The shape of the stationary segment and its properties are in a qualitative agreement
