Abstract: Methods, computing systems, and technology for optimizing a landing page of a website are presented. The system can receive, from a user device, a first web address associated with a first webpage of the website. The system can process, using the machine-learned assessment model, the first webpage to generate a first landing page score. The system can determine, based on the first landing page score and using a machine-learned optimization model, an actionable suggestion associated with the landing page. The system can cause, on a display of the user device, a presentation of the actionable suggestion.

Abstract: A cellular material barrier system for reducing sound transmission. The cellular material system includes a planar cellular metamaterial arrangement which includes at least one unit cell, the unit cell includes a sound normalizing arrangement, and a planar metamaterial arrangement coupled to the sound normalizing arrangement on a first side, the planar metamaterial arrangement includes a plate, and a frame affixed to the plate, the sound normalizing arrangement configured to normalize incident sound received at non-normal angle to thereby convey sound at normal angles to the planar metamaterial arrangement, the unit cell further comprising a back layer that is coupled to the sound normalizing arrangement on a second side, opposite the first side, the back layer is made from a porous material, including at least one of a fibrous layer, polymeric foams, ceramic foams, and metallic foams.
