Accurate Measurement of High-Bandwidth Nanomilling Forces

Accurate bandwidth measurement in xDSL service networks

In xDSL service networks, accurate bandwidth measurement is essential for network management and traffic engineering, such as isolating line faults and verifying guaranteed quality of service specifications, where ISP and xDSL service providers may be involved. Existing Internet bandwidth measurement techniques are not suitable because link asymmetry and ATM traffic shaping in xDSL deployments ...

The Effect of High Heel Shoes on Tibiofemoral and Patellofemoral joint Contact Forces and Muscle Forces

Introduction: High heel shoes affect the knee joint and can cause arthritis in the tibiofemoral (TFJ) and patellofemoral joints (PFJ). There is a dearth of research investigating the contact forces of TFJ and PFJ. Therefore, the purpose of this study was to assess the effect of high heel shoes on muscle forces as well as TFJ, and PFJ contact forces during walking.   Materials & Methods: A tot...

Java-based tools for accurate bandwidth measurement of Digital Subscriber Line networks

This paper presents the design and implementation of Java-based tools for accurate bandwidth measurement for xDSL (Digital Subscriber Line) networks, including the ADSL (Asymmetric DSL) case with different upstream and downstream bandwidths. First, a multi-packet bandwidth measurement technique is presented, based on the integration of packet-pair and filtering techniques. Considering the impor...

Direct measurement of thermophoretic forces.

We study the thermophoretic motion of a micron sized single colloidal particle in front of a flat wall by evanescent light scattering. To quantify thermophoretic effects we analyse the nonequilibrium steady state (NESS) of the particle in a constant temperature gradient perpendicular to the confining walls. We propose to determine thermophoretic forces from a "generalized potential" associated ...
