Euler equations (fluid dynamics)In fluid dynamics, the Euler equations are a set of quasilinear partial differential equations governing adiabatic and inviscid flow. They are named after Leonhard Euler. In particular, they correspond to the Navier–Stokes equations with zero viscosity and zero thermal conductivity. The Euler equations can be applied to incompressible or compressible flow. The incompressible Euler equations consist of Cauchy equations for conservation of mass and balance of momentum, together with the incompressibility condition that the flow velocity is a solenoidal field.
Slope stability analysisSlope stability analysis is a static or dynamic, analytical or empirical method to evaluate the stability of slopes of soil- and rock-fill dams, embankments, excavated slopes, and natural slopes in soil and rock. It is performed to assess the safe design of a human-made or natural slopes (e.g. embankments, road cuts, open-pit mining, excavations, landfills etc.) and the equilibrium conditions. Slope stability is the resistance of inclined surface to failure by sliding or collapsing.
Internet celebrityAn Internet celebrity (also known as a social media influencer, social media personality, internet personality, or influencer) is a celebrity who has acquired or developed their fame and notability on the Internet. The rise of social media has helped people increase their outreach to a global audience. Today, internet celebrities are found on popular online platforms such as Facebook, YouTube, Instagram, WeChat, TikTok, QQ, Snapchat, Myspace, OnlyFans, Telegram, Twitter, Twitch, and Reddit.
Influencer marketingInfluencer marketing (also known as influence marketing) is a form of social media marketing involving endorsements and product placement from influencers, people and organizations who have a purported expert level of knowledge or social influence in their field. Influencers are someone (or something) with the power to affect the buying habits or quantifiable actions of others by uploading some form of original—often sponsored—content to social media platforms like Instagram, YouTube, Snapchat, TikTok or other online channels.
