CoAx is a publically traded company that manufactures and sells coaxial and fiber-optical cable. The company has two transactions where they must determine the appropriate way to recognize revenue. In Transaction 1, CoAx entered an agreement to sell 1,000 feet of 18 American wire gage coaxial cable for $3 a foot to CableCo. The agreement requires CoAx to hold the cable in its warehouse until CableCo can transport the cable to its own warehouse. CoAx concluded that risk of ownership have passed…

This lab module covers the subjects of optical spectroscopy of gas discharges and bond stiffness of materials. Optical spectroscopy can be observed using different types of equipment, such as, a spectrometer, a light collecting fiber, and tubes of certain types of gas (He, H2O, H2 and O2). The data collected displays the peak wavelengths for each of the gases, which can be used to determine the energy released when the electrons change energy levels. Overall, it was interesting to see how…

Although the painting is titled, Mountains and Sea, the image is not representational. There is a slight indication of a landscape, but the objects are, for the most part, unrecognizable. The thinned paint creates optical space when the paint seeps into the canvas, and stains the fibers. As Greenberg states, the ‘paint seeps into the canvas … they become a single entity’ (Varieties in Modernism, p. 194). The image abandons tangible space through the unity of paint and canvas. This technique…

great in the whiteness, the grease content and the bacterial content of washed chicken feather fibers. Visual observation, infrared spectroscopy, optical microscopy and scanning electron microscopy were used to characterise the feathers and residues after extraction.The conclusion was that the effect of washed chicken feather fibers by biological method was superior to that of washed chicken feather fibers by chemical method. The whiteness was 70.3%, the grease content was 0.82% and the…

wireless technologies competed with each other, but generally, they are complementary to each other. For the most part, core infrastructure and backhaul transport for wireless networks are based on wire line technologies, whether copper wire or optical fiber. 1.2.1 Bandwidth Management Operators are both considering and implementing several techniques for managing bandwidth which are as follows (a) More Spectrum: Spectrum correlates directly to capacity, and…

be bashed and shaped in many variations). Special Fedoras have a ventilated crown with grommets, meshinlets or with penetrations for a better air circulation. A mesh is a barrier made of connected strands of metal, fiber, or other flexible/ductile materials. Silicon carbide fibers, where the basic polymers are not hydrocarbons but…

Q1.Ethernet has become the standard for LAN communications. Give a brief overview of structure of an Ethernet frame. Ethernet and Wi-Fi are the most commonly used technologies to set up Local Area Networks today. It operates by using Carrier Sense Multiple Access Detection (CSMA/CD) to control media access. (Study CCNA, 2016) The structure of an Ethernet Frame is as follows: The Ethernet Frame Structure (Anon., 2013) Explanation: • Preamble: This field is responsible for harmonizing bits…

Introduction Neural circuits which are involved in fear/threat learning and emotional memory have been studied in various ways including human subjects and laboratory animals. We will first discuss the basic circuits involved in fear conditioning and emotional memory learning. After that, two specific systems – norepinephrine (NE) projections from locus coeruleus (LC) and serotonin (5-HT) projections from dorsal raphe nuclei (DR) – and its effects on threat learning and fear conditioning will…

Sensation and perception work together to help the brain make sense of the world we see. There cells, called sensory receptors, are the ones that send stimulus to the brain through afferent nerves, which are responsible for carrying information to the brain and spinal cord. This process is called the bottom-up processing, and it means that the information is being sent to the brain for interpretation. Then there is top-down processing, which works opposite of bottom-up processing. To make sense…
