Estimated Sign
The estimated sign or estimated symbol, , (officially, the ℮-mark or the final EC verification mark in EU law,) can be found on most prepackaged products in the European Union (EU). Its use indicates that the prepackage fulfils EU Directive 76/211/EEC, which specifies the maximum permitted tolerances in package content. The shape and dimensions of the e-mark are defined in EU Directive 2009/34/EC. The e-mark is also used on prepackages in the United Kingdom, Australia and South Africa. It must be placed in the same field of vision as the nominal weight or volume quantity, for example, "1mg℮" or "1L℮". Functions The estimated sign indicates that: * the average quantity of product in a batch of prepackages shall not be less than the nominal quantity stated on the label; * the proportion of individual prepackages having a negative error greater than the tolerable negative error shall be sufficiently small for batches of prepackages to satisfy the requirements of the offi ...

Estimated Sign Detail
Estimation (or estimating) is the process of finding an estimate or approximation, which is a value that is usable for some purpose even if input data may be incomplete, uncertain, or unstable. The value is nonetheless usable because it is derived from the best information available.C. Lon Enloe, Elizabeth Garnett, Jonathan Miles, ''Physical Science: What the Technology Professional Needs to Know'' (2000), p. 47. Typically, estimation involves "using the value of a statistic derived from a sample to estimate the value of a corresponding population parameter".Raymond A. Kent, "Estimation", ''Data Construction and Data Analysis for Survey Research'' (2001), p. 157. The sample provides information that can be projected, through various formal or informal processes, to determine a range most likely to describe the missing information. An estimate that turns out to be incorrect will be an overestimate if the estimate exceeds the actual result and an underestimate if the estimate fa ...

USAID
The United States Agency for International Development (USAID) is an agency of the United States government that has been responsible for administering civilian United States foreign aid, foreign aid and development assistance. Established in 1961 and reorganized in 1998, USAID has implemented programs in global health, disaster relief, socioeconomic development, education, environmental protection, and democratic governance. With average annual disbursements of about $23 billion since 2001, USAID has been one of the world's List of development aid country donors, largest aid agencies and accounts for most U.S. foreign assistance — the highest in the world in absolute dollar terms — with missions in over 100 countries, primarily in Africa, Asia, Latin America, the Middle East, and Eastern Europe. The Trump administration is attempting to fully close the agency, pending several court cases. In early March, Secretary of State Marco Rubio announced that 83% of USAID programs wou ...

Unicode Consortium
The Unicode Consortium (legally Unicode, Inc.) is a 501(c)(3) non-profit organization incorporated and based in Mountain View, California, U.S. Its primary purpose is to maintain and publish the Unicode Standard which was developed with the intention of replacing existing character encoding schemes that are limited in size and scope, and are incompatible with multilingual environments. Unicode's success at unifying character sets has led to its widespread adoption in the internationalization and localization of software. The standard has been implemented in many technologies, including XML, the Java programming language, Swift, and modern operating systems. Members are usually but not limited to computer software and hardware companies with an interest in text-processing standards, including Adobe, Apple, the Bangladesh Computer Council, Emojipedia, Facebook, Google, IBM, Microsoft, the Omani Ministry of Endowments and Religious Affairs, Monotype Imaging, Netflix, Sales ...

European Union
The European Union (EU) is a supranational union, supranational political union, political and economic union of Member state of the European Union, member states that are Geography of the European Union, located primarily in Europe. The union has a total area of and an estimated population of over 449million as of 2024. The EU is often described as a ''sui generis'' political entity combining characteristics of both a federation and a confederation. Containing 5.5% of the world population in 2023, EU member states generated a nominal gross domestic product (GDP) of around €17.935 trillion in 2024, accounting for approximately one sixth of global economic output. Its cornerstone, the European Union Customs Union, Customs Union, paved the way to establishing European Single Market, an internal single market based on standardised European Union law, legal framework and legislation that applies in all member states in those matters, and only those matters, where the states ...

EU Directive
A directive is a legal act of the European Union that requires Member state of the European Union, member states to achieve particular goals without dictating how the member states achieve those goals. A directive's goals have to be made the goals of one or more new or changed national laws by the member states before this legislation applies to individuals residing in the member states. Directives normally leave member states with a certain amount of leeway as to the exact rules to be adopted. Directives can be adopted by means of a variety of European Union legislative procedure, legislative procedures depending on their subject matter. The text of a draft directive (if subject to the co-decision process, as contentious matters usually are) is prepared by the European Commission, Commission after consultation with its own and national experts. The draft is presented to the European Parliament, Parliament and the Council of the European Union, Council—composed of relevant min ...

Engineering Tolerance
Engineering tolerance is the permissible limit or limits of variation in: # a physical dimension; # a measured value or physical property of a material, manufactured object, system, or service; # other measured values (such as temperature, humidity, etc.); # in engineering and safety, a physical distance or space (tolerance), as in a truck (lorry), train or boat under a bridge as well as a train in a tunnel (see structure gauge and loading gauge); # in mechanical engineering, the space between a bolt and a nut or a hole, etc. Dimensions, properties, or conditions may have some variation without significantly affecting functioning of systems, machines, structures, etc. A variation beyond the tolerance (for example, a temperature that is too hot or too cold) is said to be noncompliant, rejected, or exceeding the tolerance. Considerations when setting tolerances A primary concern is to determine how wide the tolerances may be without affecting other factors or the outcome of a ...

Average
In colloquial, ordinary language, an average is a single number or value that best represents a set of data. The type of average taken as most typically representative of a list of numbers is the arithmetic mean the sum of the numbers divided by how many numbers are in the list. For example, the mean or average of the numbers 2, 3, 4, 7, and 9 (summing to 25) is 5. Depending on the context, the most representative statistics, statistic to be taken as the average might be another measure of central tendency, such as the mid-range, median, Mode (statistics), mode or geometric mean. For example, the average income, personal income is often given as the median the number below which are 50% of personal incomes and above which are 50% of personal incomes because the mean would be higher by including personal incomes from a few billionaires. General properties If all numbers in a list are the same number, then their average is also equal to this number. This property is shared by each o ...

Real Versus Nominal Value
The distinction between real value and nominal value occurs in many fields. From a philosophical viewpoint, nominal value represents an accepted condition, which is a goal or an approximation, as opposed to the real value, which is always present. Measurement In manufacturing, a ''nominal size'' or ''trade size'' is a size "in name only" used for identification. The nominal size may not match any dimension of the product, but within the domain of that product the nominal size may correspond to a large number of highly standardized dimensions and tolerances. Nominal sizes may be well-standardized across an industry, or may be proprietary to one manufacturer. Applying the nominal size across domains requires understanding of the size systems in both areas; for example, someone wishing to select a drill bit to clear a "-inch screw" may consult tables to show the proper drill bit size. Someone wishing to calculate the load capacity of a steel beam would have to consult tables to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unicode
Unicode or ''The Unicode Standard'' or TUS is a character encoding standard maintained by the Unicode Consortium designed to support the use of text in all of the world's writing systems that can be digitized. Version 16.0 defines 154,998 Character (computing), characters and 168 script (Unicode), scripts used in various ordinary, literary, academic, and technical contexts. Unicode has largely supplanted the previous environment of a myriad of incompatible character sets used within different locales and on different computer architectures. The entire repertoire of these sets, plus many additional characters, were merged into the single Unicode set. Unicode is used to encode the vast majority of text on the Internet, including most web pages, and relevant Unicode support has become a common consideration in contemporary software development. Unicode is ultimately capable of encoding more than 1.1 million characters. The Unicode character repertoire is synchronized with Univers ...

Approximation Error
The approximation error in a given data value represents the significant discrepancy that arises when an exact, true value is compared against some approximation derived for it. This inherent error in approximation can be quantified and expressed in two principal ways: as an absolute error, which denotes the direct numerical magnitude of this discrepancy irrespective of the true value's scale, or as a relative error, which provides a scaled measure of the error by considering the absolute error in proportion to the exact data value, thus offering a context-dependent assessment of the error's significance. An approximation error can manifest due to a multitude of diverse reasons. Prominent among these are limitations related to computing machine precision, where digital systems cannot represent all real numbers with perfect accuracy, leading to unavoidable truncation or rounding. Another common source is inherent measurement error, stemming from the practical limitations of inst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CE Marking
The presence of the logo on Product (business), commercial products indicates that the Manufacturing, manufacturer or importer affirms the goods' conformity with European Environment, health and safety, health, safety, and environmental protection Technical standard, standards. It is not a quality indicator or a certification mark. The CE marking is required for goods sold in the European Economic Area (EEA); goods sold elsewhere may also carry the mark. The mark indicates that the product may be traded freely in any part of the European Economic Area, regardless of its country of origin. It consists of the CE logo and, if applicable, the four digit identification number of the notified body involved in the conformity assessment procedure. Meaning The mark on a product indicates that the manufacturer or importer of that product affirms its compliance with the relevant European Union law, EU legislation and the product may be sold anywhere in the European Economic Area (EEA) ...
