No measure described to date reflects the ability of muscles to stabilise the lumbar spine. A static model was developed in supine crook lying, to measure active rotatory control with trunk loading in the sagittal plane via low, unilateral leg load. The hypothesis was that excessive lumbar movement indicates an inability of the stabilising muscles to automatically co-ordinate appropriate muscle...

Emerging Metro Ethernets create new opportunities to converge data and telephony services. However, to connect legacy telephony equipment, networks have to meet customary QoS requirements even at the presence of bursty data cross traffic. We show with active probing measurements that without appropriate mechanisms the QoS requirements cannot be met. Thus, mechanisms for priorization are needed.

It is widely believed that the popular AS path prepending (ASPP) method is very effective in controlling the inbound traffic for multi-homed AS. The ASPP method artificially increases the length of the AS path advertised in BGP routes with the hope of discouraging the upstream AS from using the prepended routes. But the result of this method is usually unpredictable, i.e. the amount of traffic ...

Abstract— An active approach to sensing can provide the focused measurement capability over a wide field of view which allows correctly formulated Simultaneous Localisation and Map-Building (SLAM) to be implemented with vision, permitting repeatable long-term localisation using only naturally occurring, automatically-detected features. In this paper we present the first example of a general sys...

 Measures active, reactive, and apparent energies  Current, voltage RMS and instantaneous measurement  Frequency measurement  Ripple-free active energy pulsed output  Live and neutral monitoring for tamper detection  Fast and simple one-point digital calibration over the whole current range  Integrated linear voltage regulators for digital and analog supply  Selectable RC or crystal osc...

This paper introduces a new surface measurement method for potential online surface measurement application. It features high stability due to using near common-path configuration combined with active stabilisation. The active stabilisation is supplied by the use of a multiplexed reference interferometer and piezo-electric translator mounted mirror. The active compensation makes the system resi...

Tectonic processes are major factors controlling landform development in tectonically active areas. In order to evaluate quantitative measurement of tectonic activities in the Alamarvdasht basin in the south of Iran, six different morphological indices including stream-gradient index (SL), drainage basin asymmetry (Af), hypsometric integral (Hi), valley floor width-valley height ratio (Vf), dra...

PURPOSE The purpose of this study was to investigate the effect of bilberry on night visual acuity (VA) and night contrast sensitivity (CS). METHODS This study utilized a double-blind, placebo-controlled, crossover design. The subjects were young males with good vision; eight received placebo and seven received active capsules for three weeks. Active capsules contained 160 mg of bilberry extr...
