Diminishing returns The law of diminishing returns (also law of diminishing marginal returns or law of increasing relative cost) states that in all productive processes, adding more of one factor of production, while holding all others constant ("ceteris paribus"), will at some point yield lower per-unit returns.[1] The law of diminishing returns does not imply that adding more of a factor will decrease the total production, a condition known as negative returns, though in fact this is common. For example, the use of fertilizer improves crop production on farms and in gardens; but at some point, adding more and more fertilizer improves the yield less per unit of fertilizer, and excessive quantities can even reduce the yield. A common sort of example is adding more workers to a job, such as assembling a car on a factory floor. At some point, adding more workers causes problems such as workers getting in each other's way or frequently finding themselves waiting for access to a part. History[edit] where

Power law An example power-law graph, being used to demonstrate ranking of popularity. To the right is the long tail, and to the left are the few that dominate (also known as the 80–20 rule). In statistics, a power law is a functional relationship between two quantities, where a relative change in one quantity results in a proportional relative change in the other quantity, independent of the initial size of those quantities: one quantity varies as a power of another. Empirical examples of power laws[edit] Properties of power laws[edit] Scale invariance[edit] One attribute of power laws is their scale invariance. , scaling the argument by a constant factor causes only a proportionate scaling of the function itself. That is, scaling by a constant simply multiplies the original power-law relation by the constant . and , and the straight-line on the log-log plot is often called the signature of a power law. Lack of well-defined average value[edit] A power-law has a well-defined mean over only if for where , and .

Sexagenary cycle Historical method for reckoning time in China The sexagenary cycle, also known as the Stems-and-Branches or ganzhi (Chinese: 干支), is a cycle of sixty terms, each corresponding to one year, thus a total of sixty years for one cycle, historically used for recording time in China and the rest of the East Asian cultural sphere.[1] It appears as a means of recording days in the first Chinese written texts, the Shang oracle bones of the late second millennium BC. Its use to record years began around the middle of the 3rd century BC. The cycle and its variations have been an important part of the traditional calendrical systems in Chinese-influenced Asian states and territories, particularly those of Japan, Korea, and Vietnam, with the old Chinese system still in use in Taiwan, and to a lesser extent, in Mainland China.[3] This traditional method of numbering days and years no longer has any significant role in modern Chinese time-keeping or the official calendar.

Great piano sounds? John, Welcome to the forum. You've received some excellent advice from wrench45us. Having some experience with synthesizers and my search for the "perfect" digital/acoustic piano, I wouldn't expect either Dimension or Rapture to fill this role--that's not where their strengths lie. Dimension is excellent for looping and dance music. With synthesizers, you must pick the right tool for the job. I'm being rather narrow in my application here simply to illustrate a point. The best a. piano sounds come from romplers and modelers. By the way, PianoTek has a nice demo you can download. Might I suggest you extend your search to other forums like PianoWorld, Keyboard Magazine, Harmony Central, and others?

Preferential attachment Definition[edit] A preferential attachment process is a stochastic urn process, meaning a process in which discrete units of wealth, usually called "balls", are added in a random or partly random fashion to a set of objects or containers, usually called "urns". A preferential attachment process is an urn process in which additional balls are added continuously to the system and are distributed among the urns as an increasing function of the number of balls the urns already have. In the most commonly studied examples, the number of urns also increases continuously, although this is not a necessary condition for preferential attachment and examples have been studied with constant or even decreasing numbers of urns. Linear preferential attachment processes in which the number of urns increases are known to produce a distribution of balls over the urns following the so-called Yule distribution. for k ≥ k0 (and zero otherwise), where B(x, y) is the Euler beta function: History[edit]

Chinese Four Pillars of Destiny (Ba Zi) Calculator The year of your birth (with its corresponding animal sign) represents only the most general of characteristics - i.e., those which may be shared with everyone who happens to be born in that year. A much more detailed personal analysis is provided by exploring all Four Pillars, taking into account not only the year, but also the month, day, and hour of birth. Each of the pillars is made up of two characters: (1) a Heavenly Stem, representing the quality of elemental force, and (2) an Earthly Branch, representing the way this is expressed. There are ten Heavenly Stems, each combining one of the five classical Chinese elements with either positive (Yang) or negative (Yin) energy. The Ten Heavenly Stems Analysis of the Four Pillars involves considering each of the Pillars in turn. The Year Pillar The Year Pillar represents the characteristics that you may expect to share with the cohort of people who are born in the same year. The Month Pillar The Day Pillar The Hour Pillar Integrating the Pillars

best piano soft synth Electronic Musician picked Akoustik Piano as the best in their review of soft pianos (a year ago, though) - over Ivory. I'm sure Ivory is great, but Akoustik price dropped to $199 this year (NI seems to be getting more aggressive on pricing), so the difference in price is meaningful. Lots of pros seem to swear by Ivory, though. If you're lucky, you'll have friends who have the various software packages so you can try them out. If you're like most, though, you'll just to have to weigh the reviews and jump for one, for better or for worse. Too many choices for piano, and there are hot new contestants this year.

Jevons paradox The Jevons paradox has been used to argue that energy conservation may be futile, as increased efficiency may increase fuel use. Nevertheless, increased efficiency can improve material living standards. Further, fuel use declines if increased efficiency is coupled with a green tax or other conservation policies that keep the cost of use the same (or higher).[3] As the Jevons paradox applies only to technological improvements that increase fuel efficiency, policies that impose conservation standards and increase costs do not display the paradox. History[edit] The Jevons paradox was first described by the English economist William Stanley Jevons in his 1865 book The Coal Question. At that time many in Britain worried that coal reserves were rapidly dwindling, but some experts opined that improving technology would reduce coal consumption. Cause[edit] Elastic Demand for Work: A doubling of fuel efficiency more than doubles work demanded, increasing the amount of fuel used. See also[edit]

The Correct Way of Calculating the Hour of Birth in Four Pillars of Destiny - Ancient and Chinese Astrology This article is about correctly calculating the hour of birth in Four Pillars of Destiny. Please read it carefully. You may know your time of birth to the minute and the BaZi astrologer can calculate your Hour Pillar incorrectly, which will actually change your chart. This is because there are several ways of calculating the hour of birth in BaZi. Underestimating the importance of the Hour Pillar in BaZi One can often read that the time of birth in the Four Pillars of Destiny system, that is, the Hour Pillar, begins to act and strengthen in the second half of the native’s life and even at the end of their life. Astrology is a science: it does not need dubious explanations I have also read arguments, even from people trained in the East, claiming that just as the hour of birth is recorded, so it is to be used. Calculating the hour of birth correctly in BaZi Which one, then, is the right way of calculating the time of birth in Chinese Astrology? It’s time for a real example. What followed?
