Value at riskValue at risk (VaR) is a measure of the risk of loss of investment/Capital. It estimates how much a set of investments might lose (with a given probability), given normal market conditions, in a set time period such as a day. VaR is typically used by firms and regulators in the financial industry to gauge the amount of assets needed to cover possible losses. For a given portfolio, time horizon, and probability p, the p VaR can be defined informally as the maximum possible loss during that time after excluding all worse outcomes whose combined probability is at most p.
Earthquake warning systemAn earthquake warning system or earthquake early warning system is a system of accelerometers, seismometers, communication, computers, and alarms that is devised for notifying adjoining regions of a substantial earthquake while it is in progress. This is not the same as earthquake prediction, which is currently incapable of producing decisive event warnings. An earthquake is caused by the release of stored elastic strain energy during rapid sliding along a fault.
Entropic value at riskIn financial mathematics and stochastic optimization, the concept of risk measure is used to quantify the risk involved in a random outcome or risk position. Many risk measures have hitherto been proposed, each having certain characteristics. The entropic value at risk (EVaR) is a coherent risk measure introduced by Ahmadi-Javid, which is an upper bound for the value at risk (VaR) and the conditional value at risk (CVaR), obtained from the Chernoff inequality. The EVaR can also be represented by using the concept of relative entropy.
Sustainable cityThe sustainable city, eco-city, or green city is a city designed with consideration for social, economic, environmental impact (commonly referred to as the triple bottom line), and resilient habitat for existing populations, without compromising the ability of future generations to experience the same. The UN Sustainable Development Goal 11 defines sustainable cities as those that are dedicated to achieving green sustainability, social sustainability and economic sustainability.
Haitian CreoleHaitian Creole (ˈheɪʃən_ˈkriːoʊl; kreyòl ayisyen, kɣejɔl ajisjɛ̃; créole haïtien, kʁe.ɔl ai.sjɛ̃), commonly referred to as simply Creole, or Kreyòl in the Creole language, is a French-based creole language spoken by 10–12 million people worldwide, and is one of the two official languages of Haiti (the other being French), where it is the native language of the vast majority of the population. Northern, Central, and Southern dialects are the three main dialects of Haitian Creole.
Haitian RevolutionThe Haitian Revolution (révolution haïtienne or La guerre de l'indépendance ʁevɔlysjɔ̃ a.i.sjɛn; Lagè d Lendependans) was a successful insurrection by self-liberated slaves against French colonial rule in Saint-Domingue, now the sovereign state of Haiti. The revolt began on 22 August 1791, and ended in 1804 with the former colony's independence. It involved black, biracial, French, Spanish, British, and Polish participants—with the ex-slave Toussaint Louverture emerging as Haiti's most prominent general.
Urban geographyUrban geography is the subdiscipline of geography that derives from a study of cities and urban processes. Urban geographers and urbanists examine various aspects of urban life and the built environment. Scholars, activists, and the public have participated in, studied, and critiqued flows of economic and natural resources, human and non-human bodies, patterns of development and infrastructure, political and institutional activities, governance, decay and renewal, and notions of socio-spatial inclusions, exclusions, and everyday life.
Haitian VodouHaitian Vodou is an African diasporic religion that developed in Haiti between the 16th and 19th centuries. It arose through a process of syncretism between several traditional religions of West and Central Africa and Roman Catholicism. There is no central authority in control of the religion and much diversity exists among practitioners, who are known as Vodouists, Vodouisants, or Serviteurs. Vodou revolves around spirits known as lwa.

Sustainable transportSustainable transport refers to ways of transportation that are sustainable in terms of their social and environmental impacts. Components for evaluating sustainability include the particular vehicles used for road, water or air transport; the source of energy; and the infrastructure used to accommodate the transport (roads, railways, airways, waterways, canals and terminals). Transport operations and logistics as well as transit-oriented development are also involved in evaluation.
