ct such as color or width inconsistencies, slubs, broken ends, etc. The tests on the quality of yarns are usually performed at the output of spinning-mills. Quality test runs for looms and knitting machines require interruption of the weaving process. This interruption is not practically feasible for the machines that are intended for large production runs of fabric rolls. The quality test is c...

A precise, accurate and well documented method for the sizing and counting of microbubbles is essential for all aspects of quantitative microbubble-enhanced ultrasound imaging. The efficacy of (a) electro-impedance volumetric zone sensing (ES) also called a Coulter counter/multisizer; (b) optical microscopy (OM); and (c) laser diffraction (LD), for the sizing and counting of microbubbles was as...

The GIGAswitch system is a high-performance packet-switching platform built on a 36-port 100 Mb/s crossbar switching fabric. The crossbar is data link independent and is capable of making 6.25 million connections per second. Digital's first GIGAswitch system product uses 2-port FDDI line cards to construct a 22-port IEEE 802.1d FDDI bridge. The FDDI bridge implements distributed forwarding in h...

This paper presents FabricKeyboard: a novel deformable keyboard interface based on a multi-modal fabric sensate surface. Multi-layer fabric sensors that detect touch, proximity, electric field, pressure, and stretch are machine-sewn in a keyboard pattern on a stretchable substrate. The result is a fabric-based musical controller that combines both the discrete controls of a keyboard and various...

There are instruments available to measure the drape coefficient of fabric. The most widely accepted method (IS 8357:1977) is hang a circular fabric sample and measure the drape coefficient. This measurement technique gives quite a bit of fair idea about drape coefficient of a fabric in static condition. But when it’s static condition is disturbed as the case in practical application of fabric ...

Osteoporosis leads to hip fractures in aging populations and is diagnosed by modern medical imaging techniques such as quantitative computed tomography (QCT). Hip fracture sites involve trabecular bone, whose strength is determined by volume fraction and orientation, known as fabric. However, bone fabric cannot be reliably assessed in clinical QCT images of proximal femur. Accordingly, we propo...

Many fabric defects are very small and undistinguishable, which makes them very difficult to detect by only monitoring the intensity change. Faultless fabric is a repetitive and regular global texture and Fourier transform can be applied to monitor the spatial frequency spectrum of a fabric. When a defect occurs in fabric, its regular structure is changed so that the corresponding intensity at ...

From the angel of environment protection, through analysing the properties of three majority types of sizing agent, such as starch(modified starch), PVA(polyvinyl alcohol) and acrylic size, we attempted to compare the sizing performance indices of several different environment protection sizing agents. We also briefly introduced several printing pastes with research values currently which could...

In this paper we consider transistor sizing to reduce crosstalk. First, crosstalk noise dependency on wire width, wire spacing, driver and receiver sizes are discussed, and validated by experiments. Then transistor sizing for timing and noise is discussed and solved using optimization techniques. Experimental results suggest that crosstalk violations can be removed by transistor sizing with ver...
