How big should the conductors be? The required size (or gauge) of the conductors depends on three factors: (1) the load impedance; (2) the length of cable required; and (3) the amount of power loss that can be tolerated. Each of these involves relationships between voltage (volts), resistance (ohms), current (amperes) and power (watts). These relationships are defined with Ohm’s Law. The job of...

the absorption properties of charge transfer organic semiconductor ttf-tcnq (tetrathiafulvalene-tetracyanoquhodimete ) filmsdeposited on kbr singlecrystal, quartz and glass substrates in far infrared have been investigated. an absorption edge at ?10 ??m was observed. photoconductivity, photoconduction efficiency and gain and photocarrier's lifetime have been measured. the results show an e...

We report fabrication of large area Ag nanowire (NW) film coated using a continuous roll-to-roll (RTR) slot die coater as a viable alternative to conventional ITO electrodes for cost-effective and large-area flexible touch screen panels (TSPs). By controlling the flow rate of shear-thinning Ag NW ink in the slot die, we fabricated Ag NW percolating network films with different sheet resistances...

We describe here the construction and testing of an IRA with dual polarity. Four feed arms are evenly spaced around the reflector, and each channel consists of a pair of arms on opposite sides of the reflector. Each channel uses a standard balun to convert the 50-ohm input impedance to 200 ohms. Since the characteristic impedance of each channel is 400 ohms, there is a 2:1 impedance mismatch at...

Subcutaneous fat layer thickness in the abdomen is a risk indicator of several diseases and disorders like diabetes and heart problems and could be used as a measure of fitness. Skinfold measurement using mechanical calipers is simple but prone to error. Ultrasound scanning techniques are yet to be established as accurate methods for this purpose. magnetic resonance imaging (MRI) and computed t...

This paper is an introduction to intersection type disciplines, with the aim of illustrating their theoretical relevance in the foundations of-calculus. We start by describing the well-known results showing the deep connection between intersection type systems and normalization properties, i.e., their power of naturally characterizing solvable, normalizing, and strongly normalizing pure-terms. ...

Electrophysiological techniques were used to determine the ion selectivity properties and the spatial distribution of the membrane conductance of amphibian Müller cells. Membrane potential changes recorded during ion substitution experiments in frog (Rana pipiens) retinal slices demonstrated that the Müller cell K+:Na+ membrane permeability ratio is approximately 490:1 and that cell Cl- permeab...

Occupancy grid maps (OGMs) are fundamental to most systems for autonomous robotic navigation. However, CPU-based implementations struggle keep up with data rates from modern 3D lidar sensors, and provide little capacity extensions which maintain richer voxel representations. This article presents Homogenous Mapping (OHM), our open source, GPU-based OGM framework. We show how the algorithms can ...
