Confinement inertiel électrostatiqueLe confinement inertiel électrostatique (en anglais Inertial electrostatic confinement ou IEC), ou plus simplement confinement électrostatique, est un procédé permettant, grâce à un champ électrostatique, de maintenir un plasma dans un volume suffisamment restreint, et à une température suffisamment élevée, de telle sorte que des réactions de fusion nucléaire puissent s'y produire. Le dispositif IEC le plus ancien et le plus connu est le fuseur de Farnsworth-Hirsch.
Image resolutionImage resolution is the level of detail an holds. The term applies to digital images, film images, and other types of images. "Higher resolution" means more image detail. Image resolution can be measured in various ways. Resolution quantifies how close lines can be to each other and still be visibly resolved. Resolution units can be tied to physical sizes (e.g. lines per mm, lines per inch), to the overall size of a picture (lines per picture height, also known simply as lines, TV lines, or TVL), or to angular subtense.
Media studiesMedia studies is a discipline and field of study that deals with the content, history, and effects of various media; in particular, the mass media. Media Studies may draw on traditions from both the social sciences and the humanities, but mostly from its core disciplines of mass communication, communication, communication sciences, and communication studies.
Influence of mass mediaIn media studies, mass communication, media psychology, communication theory, and sociology, media influence and the media effect are topics relating to mass media and media culture's effects on individuals' or audiences' thoughts, attitudes, and behaviors. Through written, televised, or spoken channels, mass media reach large audiences. Mass media's role in shaping modern culture is a central issue for the study of culture. Media influence is the actual force exerted by a media message, resulting in either a change or reinforcement in audience or individual beliefs.
