Statistical inferenceStatistical inference is the process of using data analysis to infer properties of an underlying distribution of probability. Inferential statistical analysis infers properties of a population, for example by testing hypotheses and deriving estimates. It is assumed that the observed data set is sampled from a larger population. Inferential statistics can be contrasted with descriptive statistics. Descriptive statistics is solely concerned with properties of the observed data, and it does not rest on the assumption that the data come from a larger population.
Mean-field theoryIn physics and probability theory, Mean-field theory (MFT) or Self-consistent field theory studies the behavior of high-dimensional random (stochastic) models by studying a simpler model that approximates the original by averaging over degrees of freedom (the number of values in the final calculation of a statistic that are free to vary). Such models consider many individual components that interact with each other. The main idea of MFT is to replace all interactions to any one body with an average or effective interaction, sometimes called a molecular field.
Moroccan architectureMoroccan architecture reflects Morocco's diverse geography and long history, marked by successive waves of settlers through both migration and military conquest. This architectural heritage includes ancient Roman sites, historic Islamic architecture, local vernacular architecture, 20th-century French colonial architecture, and modern architecture. Much of Morocco's traditional architecture is marked by the style that developed during the Islamic period, from the 7th century onward.
Doublet (lens)In optics, a doublet is a type of lens made up of two simple lenses paired together. Such an arrangement allows more optical surfaces, thicknesses, and formulations, especially as the space between lenses may be considered an "element". With additional degrees of freedom, optical designers have more latitude to correct more optical aberrations more thoroughly. Doublets can come in many forms, though most commercial doublets are achromats, which are optimized to reduce chromatic aberration while also reducing spherical aberration and other optical aberrations.
Moorish architectureMoorish architecture is a style within Islamic architecture which developed in the western Islamic world, including al-Andalus (on the Iberian peninsula) and what is now Morocco, Algeria, and Tunisia (part of the Maghreb). Scholarly references on Islamic architecture often refer to this architectural tradition by a more geographic designation, such as architecture of the Islamic West or architecture of the Western Islamic lands. The use of the term "Moorish" comes from the historical Western European designation of the Muslim inhabitants of these regions as "Moors".
