In this research, Surface Acoustic Wave (SAW) sensors are combined with a cascade impactor to perform real time PM10 and PM2.5 mass concentration measurements. The SAW sensors consist of 125 MHz delay lines based on Love waves propagating on an AT-cut quartz substrate. The Love waves are guided on the substrate's surface using a silica layer. SAW sensors themselves are not capable to discrimina...

Introduction: Navigated TKA (Total Knee Arthroplasty) has heightened awareness of mal-alignment in conventional TKA, as well as providing an accurate means of measuring alignment intra-operatively. Debate as to the importance and significance of alignment versus knee balance continues. Aim: To assess cutting error, and examine the hypothesises: • ‘Slotted osteotomies are more accurate than non-...

Surface acoustic wave (SAW)-based acoustofluidics shows broad applications in biomedicine and chemistry. Conventional manufacturing process for SAW devices uses photolithography metal deposition, thus requires accessing cleanroom facilities. This study presents an efficient versatile technique based on a flexible printed circuit board (FPCB) developing acoustofluidic devices. By mechanically cl...

this paper identifies eleven types of asphalt pavement distress types, commonly occuring in tehran metropolitan area. of these, five distresses namely: corrugation; utility cut depression ;pot holes; alligator cracking; and loss of bridge deck surfacing are rather common. however, others namely: shear failure; shrinkage cracks; lane joint cracks; bleeding; and shoulder distress are less prevail...

This paper presents an emulation tool and the way in which it supports the test-driven design of zerodeadlock cut-to-size plants. In contrast to previous plant layouts featuring a linear material flow, panels can now be allocated to the same saw again for their further partitioning. The resulting circles in the material flow of cut-to-size plants impose new challenges as they may cause deadlock...

In the previous lectures, we explored the problem of finding spectral sparsifiers and saw both deterministic and randomized algorithms that given a graph G with n vertices finds a spectral sparsifier with O ( n logn 2 ) edges. In this lecture, we improve upon this result to find linear-sized spectral sparsifiers, or more concretely, spectral sparsifiers with O ( n 2 ) edges. This is an interest...

STUDY DESIGN In vivo experiments using a rat model of painful facet joint distraction. OBJECTIVE To determine whether tension of the facet capsular ligament is requisite for producing pain for joint loading and to define effects on spinal glial activation. SUMMARY OF BACKGROUND DATA Cervical facet joint loading may initiate pain for certain conditions. While facet capsule tension has been p...

We report an in situ method of preparing tips for scanning probe microscopy (SPM). Oriented single-crystal nickel oxide (NiO) rods were diced, using a wafer saw, to prepare artificial breaking points. Two geometries, a single rod and a two-sided cut rod were fabricated. The cleavable tips were mounted to a force sensor based on a quartz tuning fork and cleaved using the coarse approach of the S...
