Loss has several meanings including: Loss in electronics is the ratio of the system output to system input In electronics, loss is the ratio of system output to system input. Calculation and units used are the same as with Gain, except that the output is less than the input. Loss is often expressed as a negative gain (if expressed in dB) or as a gain of less than one. For example: if input=100 mW and output=5 mW then loss = 5/100 = 0.05 = −1.3 B (bel) or −

A loss function satisfies the definition of a random variable so we can establish a cumulative distribution function and an expected value. However, more commonly, the loss function is expressed as a function of some other random variable. For example, the time that a light bulb operates before failure is a random variable and we can specify the loss, arising from having to cope in the dark and/or replace the bulb, as a function of failure time. For a continuous random variable X with probability density function f and loss function λ, the expected loss (som ...

People with unilateral hearing loss can hear normally in one ear, but have trouble hearing out of the other ear. Causes include physical trauma, or mumps (Epidemic parotitis). Profound unilateral hearing loss is a specific type of hearing impairment when one ear has no functional hearing ability (91dB or greater hearing loss). It is known to cause: Irritability Frequent headaches, stress Social isolation Trouble figuring out where sounds are coming from. Variable light diz ...

Visual loss results in the absence of vision where it existed before, which can happen either acutely (i.e. abruptly) or chronically (i.e. over a long period of time). The effects of visual loss can, before the acquisition of alternative adaptations and skills, be devastating; especially when a person's vision disappears over a short period of time. Visual loss - Acute visual loss. Acute visual loss may be dramatic in presentation, and is almost always alarming to the person experiencing the loss. It ...

In telecommunication, aperture-to-medium coupling loss is the difference between the theoretical gain of a very large antenna, such as the antennas in beyond-the-horizon microwave links, and the gain that can be realized in operation. Note 1: Aperture-to-medium coupling loss is related to the ratio of the scatter angle to the antenna beamwidth. Note 2: The "very large antennas" are referred to in wavelengths; thus, this loss can apply to line-of-sight system ...

In the context of physical health, weight loss is the process of losing body weight, typically by losing fat. To achieve weight loss, more calories must be expended than taken in. This can be achieved by reducing the amount of food consumed, increasing physical activity or a combination of the two. For healthy weight loss, most experts recommend a combination of healthy eating patterns and regular physical exercise. Other methods of losing weight include use of prescribed or herbal drugs or chemicals that decrease appetite and/or incr ...

Acute visual loss may be dramatic in presentation, and is almost always alarming to the person experiencing the loss. It may be caused by media opacities, retinal disease, optic nerve disease, visual pathway disorders, or functional disorders, or it may be in fact an acute discovery of chronic visual loss. Visual loss - Media opacity. Opacities of the clear refractive media of the eye such as the cornea, anterior chamber, lens (anatomy), and vitreous humor may cause acute visual loss as manifested b ...

One of the consequences of Bayesian inference is that in addition to experimental data, the loss function does not in itself wholly determine a decision. What is important is the relationship between the loss function and the prior probability. So it is possible to have two different loss functions which lead to the same decision when the prior probability distributions associated with each compensate for the details of each loss function. Combining the three elements of the prior probability, the data, and the loss function then allo ...

In digital systems, several techniques, used because of other advantages, may reintroduce generation loss and must be used with caution. "Compression" (more accurately "recoding with a technique that uses fewer bits" ) is often used to minimize storage or communications time used. Lossless compression is, by definition, fully reversible. Lossy compression throws away some of the information which cannot be restored. Ideally, when its use is appropriate, it would only be done once, at a carefully planned spot. Repeated applicatio ...

There is an important critique of the view held by economists that this behaviour is irrational. The implicit assumption of conventional economics is that the only relevant metric is the magnitude of the absolute change in expenditure. In the above example, saving 5% is considered equivalent to avoiding paying 5% extra. This is not the only rational interpretation. Another view is that the most important metric is the magnitude of the relative change in wealth of the decision-maker. Again, referring to the above example, a 5% discount is then no ...

Consider the following theorem (the simplest case of Ramsey's theorem and also an example of Dirichlet's pigeonhole principle): Three objects are each painted either red or blue; there must be two objects of the same color. The proof: Assume without loss of generality that the first object is red. If either of the other two objects is red, we are finished; if not, the other two objects m ...

This is also known as the razor and blades business model, referring to the most famous example. Razor handles are sold at a loss, but sales of disposable razor blades are very profitable. American businessman King Gillette famously invented the razor and blades business model, in which safety razors were sold or even given away as loss leaders so that his company could profit by selling disposable razor blades. This practice is commonly used with video game consoles. Here, the console is sold as a loss leader but the console develope ...

One use of a loss leader is to draw customers into a store where they are likely to buy other goods. The vendor expects that the typical customer will purchase other items at the same time as the loss leader and that the profit made on these items will be such that an overall profit is generated for the vendor. An example would be a supermarket selling sugar or milk at less than cost to draw customers to that particular supermarket chain. Wal-Mart uses some toys as a loss leader, leading to the potential demise of toy-only competitors like Toys "Я" Us and FAO Schwarz. (See predatory pricing.) < ...

The retained revenue from box office sales are ~50% and from DVD sales and other revenue perhaps ~50% as well. So if the gross sales aren't double the production and marketing cost it probably made a loss. The "Worldwide DVD Gross" and eventual other revenue figures are more difficult to determine. According to Regal Cinemas in 2004, the average production cost of films it showed averaged about US$63.8 million, and the average marketing cost was about $39.0 million. The averag ...

Financial success is the primary reason that studios make movies. However not all films are guaranteed to be successful. A good indication of the success of a film is to look at the budget of the movie and then see what the gross income of that film was. Studios expect that a film's "domestic" (which the film industry defines as the United States and Canada)-- as well as the overseas-- box office gross will exceed production costs. If it recoups this cost, then it can be considered a success; otherwise, if it fails by a significant ma ...

In the most dramatic cases, a single film's poor performance can push a studio into bankruptcy or equivalent financial ruin, as happened with United Artists (Heaven's Gate), Carolco Pictures (Cutthroat Island), and Squaresoft's Square Pictures (Final Fantasy: The Spirits Within). Some have even changed a company's agenda, such as Walt Disney Pictures's decision to make only 3-D animati ...

Definition and meaning of Loss Ratio :

Loss Ratio: The losses divided by the premiums paid. The numerator (losses) can be losses incurred or losses paid, and the denominator (premium) can be earned premiums or written premiums, depending on what use is going to be made of the loss ratio.
