Context: A sovereign state is, in international law, a nonphysical juridical entity that is represented by one centralised government that has sovereignty over a geographic area. International law defines sovereign states as having a permanent population, defined territory, one government, and the capacity to enter into relations with other sovereign states. It is also normally understood that a sovereign state is neither dependent on nor subjected to any other power or state., Slavonski Brod is a city in eastern Croatia, with a population of 59,000 in 2011. Located in the region of Slavonia, it is the centre of Brod-Posavina County and a river port on the Sava river., Croatia, officially the Republic of Croatia, is a sovereign state between Central Europe, Southeast Europe, and the Mediterranean. Its capital city is Zagreb, which forms one of the country's primary subdivisions, along with its twenty counties. Croatia covers and has diverse, mostly continental and Mediterranean climates. Croatia's Adriatic Sea coast contains more than a thousand islands. The country's population is 4.28 million, most of whom are Croats, with the most common religious denomination being Roman Catholicism., Bosnia and Herzegovina (or ; B&H; Bosnian, Croatian, Serbian: "Bosna i Hercegovina" / a   ), sometimes called Bosnia-Herzegovina (BiH), and, in short, often known informally as Bosnia, is a country in Southeastern Europe located on the Balkan Peninsula. Sarajevo is the capital and largest city. Bordered by Croatia to the north, west, and south; Serbia to the east; Montenegro to the southeast; and the Adriatic Sea to the south, with a coastline about long surrounding the city of Neum. In the central and eastern interior of the country the geography is mountainous, in the northwest it is moderately hilly, and the northeast is predominantly flatland. The inland is a geographically larger region and has a moderate continental climate, with hot summers and cold and snowy winters. The southern tip of the country has a Mediterranean climate and plain topography., The Adriatic Sea is a body of water separating the Italian Peninsula from the Balkan peninsula and the Apennine Mountains from the Dinaric Alps and adjacent ranges. The Adriatic is the northernmost arm of the Mediterranean Sea, extending from the Strait of Otranto (where it connects to the Ionian Sea) to the northwest and the Po Valley. The countries with coasts on the Adriatic are Albania, Bosnia and Herzegovina, Croatia, Greece, Italy, Montenegro and Slovenia. The Adriatic contains over 1,300 islands, mostly located along its eastern, Croatian, coast. It is divided into three basins, the northern being the shallowest and the southern being the deepest, with a maximum depth of . The Otranto Sill, an underwater ridge, is located at the border between the Adriatic and Ionian Seas. The prevailing currents flow counterclockwise from the Strait of Otranto, along the eastern coast and back to the strait along the western (Italian) coast. Tidal movements in the Adriatic are slight, although larger amplitudes are known to occur occasionally. The Adriatic's salinity is lower than the Mediterranean's because the Adriatic collects a third of the fresh water flowing into the Mediterranean, acting as a dilution basin. The surface water temperatures generally range from in summer to in winter, significantly moderating the Adriatic Basin's climate., A city is a large and permanent human settlement. Although there is no agreement on how a city is distinguished from a town in general English language meanings, many cities have a particular administrative, legal, or historical status based on local law., Slavonia is, with Dalmatia, Croatia proper, and Istria, one of the four historical regions of Croatia. Taking up the east of the country, it roughly corresponds with five Croatian counties: Brod-Posavina, Osijek-Baranja, Požega-Slavonia, Virovitica-Podravina and Vukovar-Srijem, although the territory of the counties includes Baranya, and the definition of the western extent of Slavonia as a region varies. The counties cover or 22.2% of Croatia, inhabited by 806,19218.8% of Croatia's population. The largest city in the region is Osijek, followed by Slavonski Brod and Vinkovci. It is located in the Pannonian Basin, largely bordered by the Danube, Drava and Sava rivers. In the west, the region consists of the Sava and Drava valleys, and the mountains surrounding the Požega Valley, and plains in the east. Slavonia enjoys a moderate continental climate, with relatively low precipitation., Brod - Posavina County ( Croatian : Brodsko - posavska županija ) is the southern Slavonian county in Croatia . Its center is the city of Slavonski Brod and it spreads along the left bank of the Sava river , hence the name Posavina . Other notable towns include Nova Gradiška ., Croats are a nation and South Slavic ethnic group at the crossroads of Central Europe, Southeast Europe, and the Mediterranean Sea. Croats mainly live in Croatia and Bosnia and Herzegovina, but are an officially recognized minority in Austria, Czech Republic, Hungary, Italy, Montenegro, Romania, Serbia, and Slovakia. Responding to political, social and economic pressure, many Croats have migrated throughout Europe (especially Germany, Austria, Switzerland, France and Italy) and the Americas (particularly the United States, Canada, Argentina, and Chile), establishing a diaspora., A mediterranean climate or dry summer climate is the climate typical of the lands in the Mediterranean Basin. The lands around the Mediterranean Sea form the largest area where this climate type is found, but it also is found in most of coastal California, in parts of Western and South Australia, in southwestern South Africa, sections of Central Asia, and in central Chile., Zagreb is the capital and the largest city of Croatia. It is located in the northwest of the country, along the Sava river, at the southern slopes of the Medvednica mountain. Zagreb lies at an elevation of approximately above sea level. In the last official census of 2011 the population of the City of Zagreb was 792,875. The wider Zagreb metropolitan area includes the City of Zagreb and the separate Zagreb County bringing the total metropolitan area population up to 1,237,887. It is the biggest metropolitan area in Croatia, and the only one with a population of over one million., Nova Gradiška is a city located in the Brod-Posavina County of Croatia, population 14,229 (2011). It is located in the historic region of Slavonia, near the border to Bosnia and Herzegovina., The Sava is a river in Central Europe, a right side tributary of the Danube. It flows through Slovenia, Croatia, along the northern border of Bosnia and Herzegovina, through Serbia, discharging into the Danube in Belgrade. Its central part is a natural border of Bosnia-Herzegovina and Croatia. The Sava forms the northern border of the Balkan Peninsula, and southern edge of the Pannonian Plain., Subject: brod-posavina county, Relation: instance_of, Options: (A) agreement (B) bank (C) body of water (D) border (E) bosnia and herzegovina (F) capital (G) catholicism (H) census (I) city (J) climate (K) climate type (L) country (M) county (N) county of croatia (O) definition (P) denomination (Q) diaspora (R) ethnic group (S) four (T) geography (U) government (V) human settlement (W) italy (X) mediterranean sea (Y) metropolitan (Z) name ([) nation (\) nova (]) plain (^) precipitation (_) religious denomination (`) republic (a) river (b) salinity (c) sea (d) serbian (e) side (f) sill (g) sovereign state (h) state (i) strait (j) territory (k) three (l) valley

Context: In signal processing, the impulse response, or impulse response function (IRF), of a dynamic system is its output when presented with a brief input signal, called an impulse. More generally, an impulse response is the reaction of any dynamic system in response to some external change. In both cases, the impulse response describes the reaction of the system as a function of time (or possibly as a function of some other independent variable that parameterizes the dynamic behavior of the system)., In signal processing, a digital filter is a system that performs mathematical operations on a sampled, discrete-time signal to reduce or enhance certain aspects of that signal. This is in contrast to the other major type of electronic filter, the analog filter, which is an electronic circuit operating on continuous-time analog signals., Infinite impulse response (IIR) is a property applying to many linear time-invariant systems. Common examples of linear time-invariant systems are most electronic and digital filters. Systems with this property are known as "IIR systems" or "IIR filters", and are distinguished by having an impulse response which does not become exactly zero past a certain point, but continues indefinitely. This is in contrast to a finite impulse response (FIR) in which the impulse response "h"("t") "does" become exactly zero at times "t" > "T" for some finite "T", thus being of finite duration., In signal processing , a finite impulse response ( FIR ) filter is a filter whose impulse response ( or response to any finite length input ) is of finite duration , because it settles to zero in finite time . This is in contrast to infinite impulse response ( IIR ) filters , which may have internal feedback and may continue to respond indefinitely ( usually decaying ) . The impulse response ( that is , the output in response to a Kronecker delta input ) of an Nth - order discrete - time FIR filter lasts exactly N + 1 samples ( from first nonzero element through last nonzero element ) before it then settles to zero . FIR filters can be discrete - time or continuous - time , and digital or analog ., Information is that which informs. In other words, it is the answer to a question of some kind. It is thus related to data and knowledge, as data represents values attributed to parameters, and knowledge signifies understanding of real things or abstract concepts. As it regards data, the information's existence is not necessarily coupled to an observer (it exists beyond an event horizon, for example), while in the case of knowledge, the information requires a cognitive observer., Signal processing is an enabling technology that encompasses the fundamental theory, applications, algorithms, and implementations of processing or transferring information contained in many different physical, symbolic, or abstract formats broadly designated as "signals". It uses mathematical, statistical, computational, heuristic, and linguistic representations, formalisms, and techniques for representation, modelling, analysis, synthesis, discovery, recovery, sensing, acquisition, extraction, learning, security, or forensics., Subject: finite impulse response, Relation: subclass_of, Options: (A) being (B) case (C) change (D) duration (E) electronic circuit (F) electronic filter (G) event (H) feedback (I) filter (J) heuristic (K) information (L) invariant (M) property (N) question (O) representation (P) security (Q) signal (R) time (S) type

Context: Prairies are ecosystems considered part of the temperate grasslands, savannas, and shrublands biome by ecologists, based on similar temperate climates, moderate rainfall, and a composition of grasses, herbs, and shrubs, rather than trees, as the dominant vegetation type. Temperate grassland regions include the Pampas of Argentina, southern Brazil and Uruguay as well as the steppes of Eurasia.
Lands typically referred to as "prairie" tend to be in North America. The term encompasses the area referred to as the Interior Lowlands of Canada, the United States, and Mexico, which includes all of the Great Plains as well as the wetter, somewhat hillier land to the east. In the U.S., the area is constituted by most or all of the states of North Dakota, South Dakota, Nebraska, Kansas, and Oklahoma, and sizable parts of the states of Montana, Wyoming, Colorado, New Mexico, Texas, Missouri, Iowa, Illinois, Ohio, Indiana, Wisconsin, and western and southern Minnesota. The Central Valley of California is also a prairie. The Canadian Prairies occupy vast areas of Manitoba, Saskatchewan, and Alberta., The Montreal Alouettes are a Canadian football team based in Montreal, Quebec. Founded in 1946, the team has folded and been revived twice. The Alouettes compete in the East Division of the Canadian Football League (CFL) and last won the Grey Cup championship in 2010. Their home field is Percival Molson Memorial Stadium for the regular season and as of 2014 also home of their playoff games., Southern Alberta is a region located in the Canadian province of Alberta. In 2004, the region's population was approximately 272,017. The primary cities are Lethbridge and Medicine Hat. The region is known mostly for agricultural production, but other sectors, such as alternative energy, film production and tourism, are emerging.
Geography.
The region has a total area of approximately 75,500 km² (29,151 sq mi)., Calgary is a city in the Canadian province of Alberta. It is situated at the confluence of the Bow River and the Elbow River in the south of the province, in an area of foothills and prairie, about east of the front ranges of the Canadian Rockies. In the 2011 census, the City of Calgary had a population of 1,096,833 and a metropolitan population of 1,214,839, making it the largest city in Alberta, and the third-largest municipality and fifth-largest census metropolitan area (CMA) in Canada., The Grey Cup is the name of both the championship game of the Canadian Football League (CFL) and the trophy awarded to the victorious team playing Canadian football. It is contested between the winners of the CFL's East and West Divisional playoffs and is one of Canadian television's largest annual sporting events. The Toronto Argonauts have 16 championships, more than any other team. The latest, the 104th Grey Cup, took place in Toronto, Ontario, on November 27, 2016, when the Ottawa Redblacks defeated the Calgary Stampeders 3933 in overtime., Lethbridge is a city in the province of Alberta, Canada, and the largest city in southern Alberta. It is Alberta's fourth-largest city by population after Calgary, Edmonton and Red Deer, and the third-largest by area after Calgary and Edmonton. The nearby Canadian Rockies contribute to the city's warm summers, mild winters, and windy climate. Lethbridge lies southeast of Calgary on the Oldman River., Alberta is a western province of Canada. With an estimated population of 4,196,457 as of July 1, 2015, it is Canada's fourth-most populous province and the most populous of Canada's three prairie provinces. Its area is about . Alberta and its neighbour Saskatchewan were districts of the Northwest Territories until they were established as provinces on September 1, 1905. The premier has been Rachel Notley since May 2015., Tulsa Golden Hurricane athletics programs include the extramural and intramural sports team of the University of Tulsa. These teams are referred to as the Tulsa Golden Hurricane (or variously as Hurricane, TU or Tulsa). Before adopting the name Golden Hurricane in 1922, the University of Tulsa (TU) had many unofficial team nicknames including Kendallites (from TU's predecessor institution Henry Kendall College), Presbyterians (from the university's founding by the Presbyterian Church), Tulsans, Tigers, Orange and Black and Yellow Jackets. The name "Golden Tornadoes" was chosen by TU football coach H.M. Archer (192224) based on new gold and black uniforms (rather than the previous orange and black) and a remark made during practice of the team "roaring through opponents" (during a season when TU went undefeated, including wins over Texas A&M and the University of Arkansas). However, it was quickly discovered that the same name had been chosen in 1917 by Georgia Tech. Archer then substituted the term "hurricane" for "tornado" and a team vote prior to leaving for the game against Texas A&M confirmed the official nickname as "Golden Hurricane"., The University of Arkansas (often shortened to U of A, UARK, or just UA) is a public, co-educational, land-grant, space-grant, research university in Fayetteville, in the U.S. state of Arkansas. It is the flagship campus of the University of Arkansas System which comprises six main campuses within the state  the University of Arkansas at Little Rock, the University of Arkansas at Monticello, the University of Arkansas at Pine Bluff, the University of Arkansas at Fort Smith, and the University of Arkansas for Medical Sciences. More than 26,000 students are enrolled in over 188 undergraduate, graduate, and professional programs. It is classified by the Carnegie Foundation as a research university with highest research activity. Founded as Arkansas Industrial University in 1871, its present name was adopted in 1899 and classes were first held on January 22, 1872. It is noted for its strong architecture, agriculture (particularly animal science and poultry science), business, communication disorders, creative writing, history, law, and Middle Eastern studies programs.<ref name="dailyheadlines.uark.edu/5292.htm"></ref>, Rachel Anne Notley (born April 17, 1964) is a Canadian politician and the 17th and current Premier of Alberta, since 2015. She is a member of the Legislative Assembly of Alberta for Edmonton-Strathcona, and leader of the Alberta New Democratic Party. The daughter of former Alberta NDP leader Grant Notley, Notley's career before politics focused on labour law, with a specialty in workers' compensation advocacy and workplace health and safety issues., FAU Stadium is a college football stadium located at the north end of the main campus of Florida Atlantic University (FAU) in Boca Raton, Florida. Opened in 2011, it is home to the Florida Atlantic Owls football team and is intended to be the first part of FAU's multi-use development project, "Innovation Village"., Canada (French: ) is a country in the northern half of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering , making it the world's second-largest country by total area and the fourth-largest country by land area. Canada's border with the United States is the world's longest land border. The majority of the country has a cold or severely cold winter climate, but southerly areas are warm in summer. Canada is sparsely populated, the majority of its land territory being dominated by forest and tundra and the Rocky Mountains. About four-fifths of the country's population of 36 million people is urbanized and live near the southern border. Its capital is Ottawa, its largest city is Toronto; other major urban areas include Montreal, Vancouver, Calgary, Edmonton, Quebec City, Winnipeg and Hamilton., The University of Tulsa (TU) is a private university located in Tulsa, Oklahoma, United States. The university is historically affiliated with the Presbyterian Church. The university offers programs in law, English, computer science, natural sciences, psychology, and engineering. Its faculty includes the Russian poet Yevgeny Yevtushenko, psychologist Robert Hogan, and political scientist Robert Donaldson. The campus's design is predominantly English Gothic., The Canadian Football League (CFL LCF) is a professional sports league in Canada. The CFL is the highest level of competition in Canadian football, a form of gridiron football closely related to American football. Its nine teams, which are located in nine separate cities, are divided into two divisions: the East Division, with four teams, and the West Division with five teams. As of 2016, the league features a 20-week regular season, which traditionally runs from late June to early November; each team plays 18 games with at least two bye weeks. Following the regular season, six teams compete in the league's three-week divisional playoffs, which culminate in the late-November Grey Cup championship, the country's largest annual sports and television event., Percival Molson Memorial Stadium (also known in French as Stade Percival-Molson; commonly referred to as Molson Stadium in English or Stade Molson in French) is an outdoor football stadium located downtown on the slopes of Mount Royal in Montreal, Quebec, Canada. Named in honour of Percival Molson, it is owned by McGill University and has been the home of the Montreal Alouettes of the Canadian Football League from 1947 to 1967 and again from 1998 to present. The stadium is also home to the McGill Redmen of the Quebec University Football League. The Selwyn House Gryphons high-school football team also play their home games at the stadium. The stadium has a capacity of 23,420 the result of a renovation project begun in 2009 that increased capacity from the previous 20,202., Jeff Perrett ( born March 23 , 1984 in Lethbridge , Alberta ) is a Canadian football offensive tackle for the Montreal Alouettes of the Canadian Football League . He was drafted by the Alouettes in the third round of the 2006 CFL Draft . He played college football for the Tulsa Golden Hurricane . Perrett was the East Division nominee for the CFL 's Most Outstanding Offensive Lineman Award in 2014 , winning the Leo Dandurand Trophy . Perrett is a Latter - day Saint ., History.
Even after the emergence of the professional National Football League (NFL), college football remained extremely popular throughout the U.S. 
Although the college game has a much larger margin for talent than its pro counterpart, the sheer number of fans following major colleges provides a financial equalizer for the game, with Division I programs  the highest level  playing in huge stadiums, six of which have seating capacity exceeding 100,000. In many cases, college stadiums employ bench-style seating, as opposed to individual seats with backs and arm rests. This allows them to seat more fans in a given amount of space than the typical professional stadium, which tends to have more features and comforts for fans. (Only two stadiums owned by U.S. colleges or universities  Papa John's Cardinal Stadium at the University of Louisville and FAU Stadium at Florida Atlantic University  consist entirely of chairback seating.), Papa John's Cardinal Stadium is a football stadium located in Louisville, Kentucky, United States, on the southern end of the campus of the University of Louisville. Debuting in 1998, it serves as the home of the Louisville Cardinals football program. The official seating capacity in the quasi-horseshoe shaped facility was 42,000 through the 2008 season. An expansion project that started after the 2008 season was completed in time for the 2010 season has brought the official capacity to 55,000. An additional expansion project aiming to close the open end of the horseshoe to add 10,000 additional seats was announced on August 28, 2015, with the goal of opening within 2 years., Subject: jeff perrett, Relation: educated_at, Options: (A) calgary (B) florida atlantic university (C) illinois (D) law (E) mcgill university (F) medicine (G) university of arkansas (H) university of arkansas at little rock (I) university of arkansas at monticello (J) university of arkansas at pine bluff (K) university of louisville (L) university of tulsa (M) wisconsin
