Internet-based recommender systems have traditionally employed collaborative filtering techniques to deliver relevant "digital" results to users. In the mobile Internet however, recommendations typically involve "physical" entities (e.g., restaurants), requiring additional user effort for fulfillment. Thus, in addition to the inherent requirements of high scalability and low latency,...
A theoretical approach to the kinetics of adsorption on the expanding interface of a micellar surfactant solution is proposed. The nonlinear partial differential equations of mass transfer of the micelles and monomers are reduced to ordinary differential equations, which are solved numerically along with the nonlinearized adsorption isotherm as a boundary condition. Being more general, this theoretical...
For surfactant Brij58, which exhibits the dynamic characteristic of slow diffusion-controlled adsorption at the air/water interface, the stress relaxation method was used to measure the Gibbs elastic modulus (ε o ) and the diffusion relaxation time (τ D ). Two other methods, the peak tensiometric method proposed recently by M. Van Uffelen and P. Joos and a strip method, were also...
