FIPS Code
The Federal Information Processing Standards (FIPS) of the United States are a set of publicly announced standards that the National Institute of Standards and Technology (NIST) has developed for use in computer systems of non-military United States government agencies and contractors. FIPS standards establish requirements for ensuring computer security and interoperability, and are intended for cases in which suitable industry standards do not already exist. Many FIPS specifications are modified versions of standards the technical communities use, such as the American National Standards Institute (ANSI), the Institute of Electrical and Electronics Engineers (IEEE), and the International Organization for Standardization (ISO). Specific areas of FIPS standardization The U.S. government has developed various FIPS specifications to standardize a number of topics including: * Codes, e.g., FIPS county codes or codes to indicate weather conditions or emergency indications. In 1994, Nat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

County (United States)
In the United States, a county or county equivalent is an Administrative division, administrative subdivision of a U.S. state, state or territories of the United States, territory, typically with defined geographic Border, boundaries and some level of governmental authority. The term "county" is used in 48 states, while Louisiana and Alaska have functionally equivalent subdivisions called List of parishes in Louisiana, parishes and List of boroughs and census areas in Alaska, boroughs, respectively. Counties and other local governments in the United States, local governments exist as a matter of U.S. state law, so the specific governmental powers of counties may vary widely between the states, with many providing some level of services to civil townships, Local government in the United States, municipalities, and Unincorporated area#United States, unincorporated areas. Certain municipalities are List of U.S. municipalities in multiple counties, in multiple counties. Some municip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

FIPS 140
The 140 series of Federal Information Processing Standards ( FIPS) are U.S. government computer security standards that specify requirements for cryptographic modules. , FIPS 140-2 and FIPS 140-3 are both accepted as current and active. FIPS 140-3 was approved on March 22, 2019 as the successor to FIPS 140-2 and became effective on September 22, 2019. FIPS 140-3 testing began on September 22, 2020, and a small number of validation certificates have been issued. FIPS 140-2 testing is still available until September 21, 2021 (later changed for applications already in progress to April 1, 2022), creating an overlapping transition period of one year. FIPS 140-2 test reports that remain in the CMVP queue will still be granted validations after that date, but all FIPS 140-2 validations will be moved to the Historical List on September 21, 2026 regardless of their actual final validation date. Purpose of FIPS 140 The National Institute of Standards and Technology (NIST) issues the 14 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Linear Predictive Coding
Linear predictive coding (LPC) is a method used mostly in audio signal processing and speech processing for representing the spectral envelope of a digital signal of speech in compressed form, using the information of a linear predictive model. LPC is the most widely used method in speech coding and speech synthesis. It is a powerful speech analysis technique, and a useful method for encoding good quality speech at a low bit rate. Overview LPC starts with the assumption that a speech signal is produced by a buzzer at the end of a tube (for voiced sounds), with occasional added hissing and popping sounds (for voiceless sounds such as sibilants and plosives). Although apparently crude, this Source–filter model is actually a close approximation of the reality of speech production. The glottis (the space between the vocal folds) produces the buzz, which is characterized by its intensity (loudness) and frequency (pitch). The vocal tract (the throat and mouth) forms the tube, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

FIPS 137
FIPS 137, originally issued as FED-STD-1015, is a secure telephony speech encoding standard for Linear Predictive Coding vocoder developed by the United States Department of Defense and finished on November 28, 1984. It was based on the earlier STANAG 4198 promulgated by NATO on February 13, 1984. FED-STD-1015 was re-designated as ''Federal Information Processing Standard'' ( FIPS) Publication 137, (FIPS PUB 137) on October 20, 1988. It is also known as "LPC-10". The codec uses a bit rate of 2.4 kbit/s, requiring 20 MIPS of processing power, 2 kilobytes of RAM and features a frame size of 22.5 ms. Additionally, the codec requires a large lookahead of 90 ms. In 1998, an improved version of the standard was introduced. With a longer super frame structure and better VQ quantizer, the bit rate In telecommunications and computing, bit rate (bitrate or as a variable ''R'') is the number of bits that are conveyed or processed per unit of time. The bit rate is expressed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Federal Information Security Management Act Of 2002
The Federal Information Security Management Act of 2002 (FISMA, , ''et seq.'') is a United States federal law enacted in 2002 as Title III of the E-Government Act of 2002 (, ). The act recognized the importance of information security to the economic and national security interests of the United States. The act requires each federal agency to develop, document, and implement an agency-wide program to provide information security for the information and information systems that support the operations and assets of the agency, including those provided or managed by another agency, contractor, or other source. FISMA has brought attention within the federal government to cybersecurity and explicitly emphasized a "risk-based policy for cost-effective security." FISMA requires agency program officials, chief information officers, and inspectors general (IGs) to conduct annual reviews of the agency's information security program and report the results to Office of Management and Budge ...

Native Hawaiians
Native Hawaiians (also known as Indigenous Hawaiians, Kānaka Maoli, Aboriginal Hawaiians, or simply Hawaiians; , , , and ) are the Indigenous Polynesian people of the Hawaiian Islands. Hawaiʻi was settled at least 800 years ago by Polynesians who sailed from the Society Islands. The settlers gradually became detached from their homeland and developed a distinct Hawaiian culture and identity in their new home. They created new religious and cultural structures, in response to their new circumstances and to pass knowledge from one generation to the next. Hence, the Hawaiian religion focuses on ways to live and relate to the land and instills a sense of community. The Hawaiian Kingdom was formed in 1795, when Kamehameha the Great, of the then-independent island of Hawaiʻi, conquered the independent islands of Oʻahu, Maui, Molokaʻi, and Lānaʻi to form the kingdom. In 1810, Kauaʻi and Niʻihau joined the Kingdom, the last inhabited islands to do so. The Kingdom recei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alaska Natives
Alaska Natives (also known as Native Alaskans, Alaskan Indians, or Indigenous Alaskans) are the Indigenous peoples of Alaska that encompass a diverse arena of cultural and linguistic groups, including the Iñupiat, Yupik, Aleut, Eyak, Tlingit, Haida, Tsimshian, and various Northern Athabaskan, as well as Russian Creoles. These groups are often categorized by their distinct language families. Many Alaska Natives are enrolled in federally recognized Alaska Native tribal entities, which are members of 13 Alaska Native Regional Corporations responsible for managing land and financial claims. The migration of Alaska Natives' ancestors into the Alaskan region occurred thousands of years ago, likely in more than one wave. Some present-day groups descend from a later migration event that also led to settlement across northern North America, with these populations generally not migrating further south. Genetic evidence indicates that these groups are not closely related to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indigenous Peoples Of The Americas
In the Americas, Indigenous peoples comprise the two continents' pre-Columbian inhabitants, as well as the ethnic groups that identify with them in the 15th century, as well as the ethnic groups that identify with the pre-Columbian population of the Americas as such. These populations exhibit significant diversity; some Indigenous peoples were historically hunter-gatherers, while others practiced agriculture and aquaculture. Various Indigenous societies developed complex social structures, including pre-contact monumental architecture, organized city, cities, city-states, chiefdoms, state (polity), states, monarchy, kingdoms, republics, confederation, confederacies, and empires. These societies possessed varying levels of knowledge in fields such as Pre-Columbian engineering in the Americas, engineering, Pre-Columbian architecture, architecture, mathematics, astronomy, History of writing, writing, physics, medicine, Pre-Columbian agriculture, agriculture, irrigation, geology, minin ...

Geographic Names Information System
The Geographic Names Information System (GNIS) is a database of name and location information about more than two million physical and cultural features, encompassing the United States and its territories; the Compact of Free Association, associated states of the Marshall Islands, Federated States of Micronesia, and Palau; and Antarctica. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names. Data were collected in two phases. Although a third phase was considered, which would have handled name changes where local usages differed from maps, it was never begun. The database is part of a system that includes topographic map names and bibliographic references. The names of books and historic maps that confirm the feature or place name are cited. Variant names, alternatives to official federal names for a feature, are also recor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
