This paper presents the fabrication, assembly, and characterization of piezoresistive nanosprings for creating nanoelectromechanical systems. The fabrication process is based on conventional microfabrication techniques to create a planar pattern in a 27nm thick, n-type InGaAs/GaAs bilayer that self-forms into three-dimensional structures during a wet etch release. As the nanosprings have lower ...

The CALICE Electromagnetic CALorimeter (ECAL) will be a silicon-tungsten sampling calorimeter [1] with 30 layers of silicon wafers, each containing an 18×18 array of diode pads, giving 9720 channels to be read out. The signal from each pad is amplified by a Very Front End (VFE) ASIC [2] which multiplexes the signals from 18 pads onto one output line. The silicon wafers and VFE chips are mounted...

Authenticated dictionaries allow users to send lookup requests to an untrusted server and get authenticated answers. Persistent authenticated dictionaries (PADs) add queries against historical versions. We consider a variety of different trust models for PADs and we present several extensions, including support for aggregation and a rich query language, as well as hiding information about the o...

The utilization of Aegle marmelos shell particles is not optimal yet. Composite brake pads are currently being developed because they eco-friendly and heat resistant compared to non-asbestos pads. This research attempt analyze the volume fraction on measure hardness, toughness, wear epoxy matrix composites as an alternative material for motorcycle design this uses a true experimental with postt...

Methods 12 fresh frozen cadaver foot and ankle specimens were used. The peroneal longus and brevis tendons, as well as the posterior tibial tendon, were identified and tagged. A flexible thin computerized pressure sensor strip (Tekscan), containing 4 sensor pads, was placed longitudinally within the groove between the peroneus brevis tendon and posterior fibula. These 4 sensor pads were separat...

Focused surface-acoustic waves ~SAWs! provide a way to reach intense acoustic fields for electroand optoacoustic applications on semiconductors. We have investigated the focusing of SAWs by interdigital transducers ~IDTs! deposited on ~100!-oriented GaAs substrates. The focusing IDTs have curved fingers designed to account for the acoustic anisotropy of the substrate. Different factors that aff...

This paper introduces a CMOS-microfluidics integration scheme for electrochemical microsystems. A CMOS chip was embedded into a micro-machined silicon carrier. By leveling the CMOS chip and carrier surface to within 100 nm, an expanded obstacle-free surface suitable for photolithography was achieved. Thin film metal planar interconnects were microfabricated to bridge CMOS pads to the perimeter ...

I show that P(2, 3) has an embedding P(2, 3) ∼= Γ ⊂ P(4, 5, 6, 9) whose image Γ is contained in a quasismooth K3 hypersurface X24 ⊂ P(4, 5, 6, 9). The pair Γ ⊂ X24 unprojects to the codimension 4 K3 surface Y ⊂ P(4, 5, 5, 6, 7, 8, 9) with Basket = [ 1 2 (1, 1), 1 5 (1, 4), 1 5 (2, 3), 1 9 (4, 5) ]. Numerator = 1− t − t − 2t − 2t − 2t − t + t + 2t + 3t + 4t + 3t + · · · (Altınok4(111) in the Mag...

The purpose of this study was to determine whether pressing a dipstick into a pad within 2 hours of urine saturation detected pyuria as effectively as immersing a dipstick in a urine specimen. Sensitivity, specificity, and positive and negative predictive values indicated that results of the pad method were as effective as those of direct dipstick into clean-catch urine in detecting pyuria. In ...
