The Scholar's Depot: Where Knowledge Meets Opportunity

What frequency should you save at for a recording? - sample at twice the rate of the highest frequency in the signal, data up to 100 Hz should be sampled at 200 Hz What is Nyquist? - is half the sample rate (the highest frequency you can reproduce) What is quantization - the process of converting a voltage, which is analog, into a number, which is digital (it creates a number that reflects a signal amplitude, one number is a 'snap shot') What is a sampling rate? - is how often you...

The sampling rate of a digital recording will influence: - D A. The overall sound pressure level of the recording B. The distance b/w the speaker's voice and harmonics C. The ambient noise level of the recording D. The amount of memory needed to process and record it A spectrum differs from a spectrogram because: - B A. It is a time domain display B. It does not represent time on its axis The relationship between perturbation and modulation is: - B A. They are mutually exclusive...

Stops - complete closure of the vocal tract momentarily is associated with _______ Fricatives - narrowing of the vocal tract/partial obstruction is associated with _______ Affricates - fairly brief stop and frication interval is associated with _________ Stops, fricatives, affricates, nasals, glides, liquids - the 3 obstruents are: ____, ______, and _____ The 3 sonorants/non-obstruents are: ______, ______, and _______ Silence, voicing energy, constriction, burst - stops are cha...

What is dissemination? - Getting the research information out to those who need to know it Publication - highest level Presenting at National Conference Presenting at Local Conference Journal Club where one person reviews an article What does a 17 on MMSE mean? - Moderate cognitive impairment What is Tegretol in the CYP450 system? - Inducer ->will lower dose of Lamictal and BCP's What do BCP's do to Lamictal? - Inducer - will lower dose of Lamictal What is a Type I res...

The hand method provides a fair estimate of: - Hose friction loss Usually has a locking ball valve - Pump discharge Must be located at the lowest part of the pump and lines - Pump drain Line must have a check valve - Pump intake Releases air into the atmosphere when a dry supply line is being charged - Bleeder valve Major advantage of a positive displacement pump over a centrifugal pump is that is can: - Pump air, making it self priming One advantage that electronic gover...

What sizes are the side and rear dump valves normally? - 10 to 12 inches in diameter and are commonly butterfly valves When tankers are equipped with large diameter gated intakes, what is required? - Slow operating valves with air bleeders and intake relief valves What is the heart of the mobile water supply apparatus? - The water tank What are the two types of water tanks found on mobile water supply apparatus? - 1. Elliptical 2. Square-cornered What are the majority of water t...

Which appliance helps move water from one dump tank to another - Jet suction What should you open first when filling a hydrant - Tank fill valve Pumper that supplies attack pumper - Source pumper Minimum capacity for supply tank - 1000 gallons New feature for tankers - In open cab/Close Proportioning ratio set by - Pump manufacturer Water shuttle main objective - Keep water moving towards draft Who on the apparatus is responsible to ensure all personnel are seated wit...

Static pressure is available pressure at a discharge point without water flowing. Once water starts flowing from a hydrant, friction loss usually reduces static pressure to? - Residual pressure To calculate the appliance pressure loss? - Add 10 psi for each appliance Identify two correct statements about hydrants - Grid systems with large supply mains and looping secondary mains generally have less friction losses and deterioration If hydrants are color coded, select a light blue hyd...

A major advantage of a positive displacement pump over a centrifugal pump is that it can: - Pump air, making it self-priming. The efficiency of many priming devices is improved through the use of: - An oil-injection system The big advantage of centrifugal pumps over positive displacement pumps is that centrifugal pumps: - Can provide water in variable pressures and volumes. On large diameter lines, gate valves are most often controlled by: - Handwheels To disengage the pump on PT...
