HHCode
A Helical Hyperspatial Code, also known as an HHCode, is a data storage format for very large spatio-temporal datasets. The development of HHCode can be traced to efforts in the 1990's by Edric Keighan, Panagiotis A. Vretanos, Michael Galluchon, and Herman P. Varma while working for the Canadian Hydrographic Service's Atlantic regional offices at the Bedford Institute of Oceanography in Dartmouth, Nova Scotia, Dartmouth, Nova Scotia. CHS was facing a problem with storing very large spatial datasets acquired during hydrographic surveys (thus having a temporal element) and was seeking a method to store the datasets in a relational database structure.US Patent 6161105
Oracle Corporation, December 2000. CHS scientists reportedly conceptualized a spatio-temporal indexing system during a hydrographic survey onboard CCGS Hudson, CCGS ''Hudson'' on Georg ...

CCGS Hudson
CCGS ''Hudson'' was an offshore oceanographic and hydrographic survey vessel operated by the Canadian Coast Guard. The ship entered service in 1963 with the Canadian Oceanographic Service, stationed at the Bedford Institute of Oceanography, called CSS ''Hudson''. The ship made several significant scientific voyages, among them the first circumnavigation of the Americas in 1970. The ship was transferred to the Canadian Coast Guard in 1996 and decommissioned in 2022. A replacement is not scheduled for delivery until 2024–2025. Description The first Canadian ship built specifically for hydrographic and oceanographic survey work, ''Hudson'' was designed by the Montreal firm of Gilmore, German and Milne. ''Hudson'' is long overall and between perpendiculars with a beam of and a draught of The ship has a tonnage of , and a . ''Hudson'' is certified as Arctic class 2. The ship is powered by a diesel electric DC/DC system composed of four Alco 251B diesel engines for propul ...

Kernel (operating System)
A kernel is a computer program at the core of a computer's operating system that always has complete control over everything in the system. The kernel is also responsible for preventing and mitigating conflicts between different processes. It is the portion of the operating system code that is always resident in memory and facilitates interactions between hardware and software components. A full kernel controls all hardware resources (e.g. I/O, memory, cryptography) via device drivers, arbitrates conflicts between processes concerning such resources, and optimizes the use of common resources, such as CPU, cache, file systems, and network sockets. On most systems, the kernel is one of the first programs loaded on startup (after the bootloader). It handles the rest of startup as well as memory, peripherals, and input/output (I/O) requests from software, translating them into data-processing instructions for the central processing unit. The critical code of the kernel is usua ...

Hull, Quebec
Hull is the central business district and oldest neighbourhood of the city of Gatineau, Quebec, Canada. It is located on the west bank of the Gatineau River and the north shore of the Ottawa River, directly opposite Ottawa. As part of Canada's National Capital Region, it contains offices for more than 20,000 civil servants. It was named after Kingston upon Hull in England. History Early history Hull is a former municipality in the Province of Quebec and the location of the oldest non-Indigenous settlement in the National Capital Region. Prior to European settlement, various Anishinaabe peoples including the Algonquins inhabited the area. It was founded on the north shore of the Ottawa River in 1800 by Philemon Wright at the portage around the Chaudière Falls just upstream (or west) from where the Gatineau and Rideau Rivers flow into the Ottawa. Wright brought his family, five other families and twenty-five labourers and a plan to establish an agriculturally based c ...

International Hydrographic Review
The International Hydrographic Organization (IHO) (French: ''Organisation Hydrographique Internationale'') is an intergovernmental organization representing hydrography. the IHO comprised 102 member states. A principal aim of the IHO is to ensure that the world's seas, oceans and navigable waters are properly surveyed and charted. It does this through the setting of international standards and through its capacity building programs and offices. The IHO enjoys observer status at the United Nations, where it is the recognized competent authority on hydrographic surveying and nautical charting. When referring to hydrography and nautical charting in conventions and similar instruments, it is the IHO standards and specifications that are normally used. History During the 19th century, many maritime nations established hydrographic offices to provide means for improving the navigation of naval and merchant vessels by providing nautical publications, nautical charts, and other nav ...

Oracle Database
Oracle Database (commonly referred to as Oracle DBMS, Oracle Autonomous Database, or simply as Oracle) is a proprietary multi-model database management system produced and marketed by Oracle Corporation. It is a database commonly used for running online transaction processing (OLTP), data warehousing (DW) and mixed (OLTP & DW) database workloads. Oracle Database is available by several service providers on-premises, on-cloud, or as a hybrid cloud installation. It may be run on third party servers as well as on Oracle hardware ( Exadata on-premises, on Oracle Cloud or at Cloud at Customer). Oracle Database uses SQL for database updating and retrieval. History Larry Ellison and his two friends and former co-workers, Bob Miner and Ed Oates, started a consultancy called Software Development Laboratories (SDL) in 1977, later Oracle Corporation. SDL developed the original version of the Oracle software. The name ''Oracle'' comes from the code-name of a CIA-funded proj ...

Hypercube
In geometry, a hypercube is an ''n''-dimensional analogue of a square ( ) and a cube ( ); the special case for is known as a ''tesseract''. It is a closed, compact, convex figure whose 1- skeleton consists of groups of opposite parallel line segments aligned in each of the space's dimensions, perpendicular to each other and of the same length. A unit hypercube's longest diagonal in ''n'' dimensions is equal to \sqrt. An ''n''-dimensional hypercube is more commonly referred to as an ''n''-cube or sometimes as an ''n''-dimensional cube. The term measure polytope (originally from Elte, 1912) is also used, notably in the work of H. S. M. Coxeter who also labels the hypercubes the γn polytopes. The hypercube is the special case of a hyperrectangle (also called an ''n-orthotope''). A ''unit hypercube'' is a hypercube whose side has length one unit. Often, the hypercube whose corners (or ''vertices'') are the 2''n'' points in R''n'' with each coordinate equal to 0 or 1 i ...

Riemann
Georg Friedrich Bernhard Riemann (; ; 17September 182620July 1866) was a German mathematician who made profound contributions to analysis, number theory, and differential geometry. In the field of real analysis, he is mostly known for the first rigorous formulation of the integral, the Riemann integral, and his work on Fourier series. His contributions to complex analysis include most notably the introduction of Riemann surfaces, breaking new ground in a natural, geometric treatment of complex analysis. His 1859 paper on the prime-counting function, containing the original statement of the Riemann hypothesis, is regarded as a foundational paper of analytic number theory. Through his pioneering contributions to differential geometry, Riemann laid the foundations of the mathematics of general relativity. He is considered by many to be one of the greatest mathematicians of all time. Early years Riemann was born on 17 September 1826 in Breselenz, a village near Dannenberg in the ...

Georges Bank
Georges Bank (formerly known as St. Georges Bank) is a large elevated area of the sea floor between Cape Cod, Massachusetts (United States), and Cape Sable Island, Nova Scotia (Canada). It separates the Gulf of Maine from the Atlantic Ocean. The origin of its name is obscure. The 1610 Velasco map, prepared for King James I of England, used the name "S. Georges Banck", a common practice when the name of the English patron saint, St. George, was sprinkled around the English-colonized world. By the 1850s, it was known simply as Georges Bank. Physical environment Georges Bank is the most westward of the great Atlantic fishing banks. The now-submerged portions of the North American mainland are comprised in the continental shelf running from the Grand Banks of Newfoundland to Georges. Georges Bank was part of the North American mainland as recently as 12,000 years ago. Roughly oval in shape, Georges Bank measures about in length by in width. Located offshore, Georges Bank i ...
