The Human–Computer Interface

Student's Evaluation of Web-Based Learning Technologies in a Humancomputer Interaction Course

The human-computer interface (HCI) field is constantly changing and designers are challenged to develop simple interactive systems implemented through sophisticated technology. At Ben-Gurion University, the introductory HCI course was originally taught in a face-to-face mode and covered theoretical knowledge on HCI theories, principles and design, and practical experience in designing and evalu...

Refraction at the Interface of a Lossy Metamaterial

The refraction phenomenon at the interface of an ordinary material and a lossy metamaterial has been investigated. For oblique incidence on the lossy metamaterial, the planes of constant amplitude of the refracted wave are parallel to the interface and the plane of constant phases make a real angle with the interface (real refraction angle). The real refraction angle and hence, the real refract...

The Influence of Bicomponent Mixed Surfactants on Drop/Interface Coalescence

Effects of binary mixtures of ionic/nonionic (sodium dodecyl sulfate/2-heptanol or 1-decanol) and nonionic/nonionic surfactants (2-heptnol/1-decanol) on drop/interface coalescence of water drops in a continuous n-heptane phase were examined. The drop size reduced appreciably and the multi-step coalescence was suppressed finally as the concentration of each of the constituting components</em...

Cement-Implant Interface Fracture Failure by Crack Initiation Due to Interface Cavity Stress Concentration

Nowadays total joint replacements are widely used in the world, so in average 800,000 joint surgeries are done yearly only in Europe and North America. However implant loosening is and remains as the major issue of all implant failures and therefore causes revision surgery procedures. Studies and experiments have identified poor fixation of implants most likely is the main cause of long term im...
