dynamic contrast ratio

Examples of dynamic contrast ratio in the following topics:

• Resolution of the Human Eye

  • The retina of human eye has a static contrast ratio of around 100:1 (about 6.5 f-stops).
  • Hence, a dynamic contrast ratio of about 1,000,000:1 (about 20 f-stops) is possible.

• Using the Receivables Turnover Ratio

  • The receivables turnover ratio measures how efficiently a firm uses its assets.
  • The receivables turnover ratio, also called the debtor's turnover ratio, is an accounting measure used to measure how effective a company is in extending credit as well as collecting debts.
  • The receivables turnover ratio is an activity ratio, measuring how efficiently a firm uses its assets.
  • A high ratio implies either that a company operates on a cash basis or that its extension of credit and collection of accounts receivable is efficient; in contrast, a low ratio implies the company is not making the timely collection of credit.
  • Sometimes the receivables turnover ratio is expressed as the "days' sales in receivables":

• Acid Test Ratio

  • The acid-test ratio, also known as the quick ratio, measures the ability of a company to use its near cash or quick assets to immediately extinguish or retire its current liabilities.
  • The acid-test ratio, like other financial ratios, is a test of viability for business entities but does not give a complete picture of a company's health.
  • In contrast, if the business has negotiated fast payment terms with customers and long payment terms from suppliers, it may have a very low quick ratio yet good liquidity .
  • A low acid-test ratio may be a sign of poor use of cash by a business.
  • The acid-test ratio is similar to the current ratio except the value of inventory is omitted from the calculation.

• Quick Ratio (Acid-Test Ratio)

  • In finance, the Acid-test (also known as quick ratio or liquid ratio) measures the ability of a company to use its near cash or quick assets to extinguish or retire its current liabilities immediately.
  • A company with a Quick Ratio of less than 1 cannot pay back its current liabilities.
  • Acid test often refers to Cash ratio instead of Quick ratio: Acid Test Ratio = (Current assets - Inventory) / Current liabilities.
  • Note that Inventory is excluded from the sum of assets in the Quick Ratio, but included in the Current Ratio.
  • In contrast, if the business has negotiated fast payment or cash from customers, and long terms from suppliers, it may have a very low Quick Ratio and yet be very healthy.

• Modeling Ecosystem Dynamics

  • Conceptual models describe ecosystem structure, while analytical and simulation models use algorithms to predict ecosystem dynamics.
  • Ecosystems are dynamic entities that are subject to a variety of abiotic and biotic disturbances.
  • Like analytical models, simulation models use complex algorithms to predict ecosystem dynamics.
  • These simulations are considered to be the most accurate and predictive of ecosystem dynamics.
  • Compare and contrast conceptual, analytical, and simulation models of ecosystem dynamics

• Application of Bernoulli's Equation: Pressure and Speed

  • The kinetic energy of the fluid is stored in static pressure, $p_s$, and dynamic pressure, $\frac{1}{2}\rho V^2$, where \rho is the fluid density in (SI unit: kg/m3) and V is the fluid velocity (SI unit: m/s).
  • The SI unit of static pressure and dynamic pressure is the pascal.
  • Static pressure is simply the pressure at a given point in the fluid, dynamic pressure is the kinetic energy per unit volume of a fluid particle.
  • Thus, a fluid will not have dynamic pressure unless it is moving.
  • The Mach number represents the ratio of the speed of an object moving through a medium to the speed of sound in the medium.

• Income Statement Analyses

  • This contrasts with the balance sheet, which represents a single moment in time.
  • Price to Earnings Ratio = Market Value of Stock / Earnings per Share
  • A higher P/E ratio means that investors are paying more for each unit of current net income, so the stock is more "expensive" than one with a lower P/E ratio.
  • The P/E ratio can be regarded as being expressed in years.
  • The ratio does not factor in expansion or debt repayment.

• Variations in Directness

  • Use force and directness to add dynamic contrast and texture to your speech.
  • s "I Have a Dream," or even Abraham Lincoln's "Gettysburg Address"—have all used force and directness to create dynamic, engaging speeches.
  • From a stylistic perspective, force and directness add moments of dynamic contrast to your speech.

• Cell Size

  • Cell size is limited in accordance with the ratio of cell surface area to volume.
  • Therefore, as a cell increases in size, its surface area-to-volume ratio decreases.
  • The higher the surface area to volume ratio they have, the more effective this process can be.
  • For small organisms with their high surface area to volume ratio, friction and fluid dynamics (wind, water flow) are relatively much more important, and gravity much less important, than for large animals.
  • Notice that as a cell increases in size, its surface area-to-volume ratio decreases.

• Dividend Yield Ratio

  • The dividend-price ratio is a company's annual dividend payments divided by market capitalization, or dividend per share divided by the price per share.
  • The dividend yield or the dividend-price ratio of a share is the company's total annual dividend payments divided by its market capitalization, or the dividend per share, divided by the price per share.
  • Its reciprocal is the Price/Dividend ratio.
  • The yield is the ratio of the annual dividend to the current market price, which will vary.
  • In contrast, some investors may find a higher dividend yield unattractive, perhaps because it increases their tax bill.
