![]() What makes a country rich is not how much money it has, but how much it produces.Ĭalculating gross domestic product (GDP) is the most common measure of national output. Economists predict that the gap won’t hit zero until at least 2018. The negative gap peaked in 2009, the weakest level in nearly three decades. ** Macroeconomics is a branch of economics that looks at large-scale economic factors, such as national production, inflation, unemployment or interest rates – things that affect or exist across the whole economy.Īccording to Viable Opposition’s website, the latest US output gap started in 2008 – it has been the longest and deepest period of negative gap since 1980. In the field of ** macroeconomics, the concept of national output is essential. ![]() In economics, output is the total quantity of goods and services that an individual, company, industry, city, region or country, or even the whole world produces in a given period. Output is the result of production – it usually refers to how much is produced. Production is the making process – it is where the raw materials and components are transformed into a product. For example, to make a ship you need various metals, plastics, wood, cables, glass, electronic components, ship-workers, welders, etc. Input refers to the raw materials, components and people you need in order to produce a finished product. As a verb, it began to take on the meaning of ‘to produce’ in 1858. Until 1830, the term in the English language referred to the iron and coal trades only. “The total value of goods produced by a company, an industry or an economy.” An output contract is an agreement in which all of a producer’s production is sold to the buyer – both the producer and the buyer commit to selling and purchasing (respectively) the entire production.Īccording to the Financial Times’ glossary of terms, output is: In contracting, the term means the desired result from a contractor or project. In web design – HTML – the tag is used to represent the result of a calculation (like one performed by a script) or the result of a user’s action. It may also refer to anywhere on an electronic device where power (or data) leaves a system. Anything we view on our computer monitor is output. In the world of computing, it refers to any data that has been processed by and sent out from a computer or similar electronic device. The term may refer to all the work, energy, goods, or services produced by an individual, company, factory or machine. This was also an interesting and informative read because it helped me determine better sensitivity settings for various stego algorithms to minimize False-Positives while at the same time reducing False-Negatives.Output refers to the total production of goods and services of a whole country over a given period – its gross domestic product. ![]() It seems to show (compared to the study on False Positives) that a False-Negative is more likely than a False-Positive. One great thing about StegDetect is that it supports the ability to train the program on new, unknown algorithms as long as you have a clean set of images and a steg'ed set of images to 'train it' on.įor a savvy user, this sort of feature can help reduce the rate of False-Positives by improving the detection ability.Īnalysis of False-Negatives w/ StegDetect Nothing is perfect, and this is some research that was done on the reliability of StegDetect. StegDetect is a well known tool for detecting a variety of steganographic algorithms. Steganography For The Computer Forensics ExaminerĪ good primer on steganography in relation to 'the real world'Īnalysis of False-Positives w/ StegDetect ![]() Many different methods and programs exist to try and suss out whether an image is steg'ed or not, but here's a couple links to research papers on the reliability of certain tools: there's no guarantee it's THE ONLY needle in there! ![]() And worst of all, even if you find a needle. There are new methods of steganography being developed and theorized all the time, so detecting it is quite literally like looking for a needle in a haystack. ![]()
