Silica or glass particles are introduced in a poly(dimethylsiloxane) (PDMS) matrix for various applications. A particular feature of these systems is that PDMS adsorbs on the surface of the dispersed particles, thus rendering them more hydrophobic with time. The mechanism of this process of in situ hydrophobization is still poorly understood. The major aims of the present study are (1) to quant...

Purpose In recent years, deep learning and extended reality (XR) technologies have gained popularity in the built environment, especially construction engineering management. A significant amount of research efforts has been thus dedicated to automation construction-related activities visualization process. The purpose this study is investigate potential opportunities integration XR Design/meth...

While head-mounted display (HMD) technologies have undergone great developments since the first HMD for 3D visualization originated by Ivan Sutherland in the 1960’s, HMD technologies have suffered from tradeoffs in capability and limitation. The main issues of HMDs include the tradeoff between resolution and field of view (FOV), the presence of large distortion for wide field of view designs, t...

INTRODUCTION The latest generation of head-mounted displays (HMDs) provides built-in head tracking, which enables estimating position in a room-size setting. This feature allows users to explore, navigate, and move within real-size virtual environments, such as kitchens, supermarket aisles, or streets. Previously, these actions were commonly facilitated by external peripherals and interaction m...

The arrival of head-mounted displays (HMDs) to the consumer market requires a novel content format that is, first, adapted to the specificities of immersive displays and, second, that takes into account the current reality of multidisplay media consumption. We review the requirements for such content format and report on existing initiatives, some of our own, towards implementing such content f...

Introduction Clustering data based on pairwise distances is a fundamental problem Weighted trees can be used to represent hierarchical clusters Multidi mensional Scaling MDS in some formulations is the problem of clustering data based on preserving their relative rather than absolute distances We call this an ordinal clustering A particular instance of this problem has been con sidered in the a...

Abstract Alkalimetalldihydrogenantimonide [M(L) x SbH 2 ], kurz: Alkalimetallantimonide (M=Li, Na, K, Rb, Cs; 1 : L=pmdta; L=Kronenether), wurden aus Stiban und n ‐Butyllithium, M(hmds) (hmds=Hexamethyldisilazan) bzw. MO t Bu hergestellt. Wir haben einen allgemein anwendbaren Syntheseweg für diese Verbindungen entwickelt die erhaltenen auf ihre Stabilität in Abhängigkeit vom verwendeten Alkalim...
