Humans commonly are considered to have five separable named senses, called hearing, sight (vision), smell, taste, and touch, providing information about the external world. These senses, their organs, and respective modalities are listed in Table 18-1. The two most dominant senses are sight and hearing. Equipment designers understand human reliance on these two senses and have used them as the ...

We have recently demonstrated the viability of silicon microarray pins, taking advantage of lithographic and batch processing of silicon micromachining in comparison with conventional and serial processing currently used for commercial pins. The reduced spot size (< 50% in diameter, i.e., > 4X in array density), however, made such undesirable needs as preprinting more pronounced. Preprinting, a...

The method of TiSiCN-coatings deposition by anodic evaporation Ti and decomposition an organosilicon precursor (hexamethyldisilazane) in a low-pressure (∼1 mTorr) nitrogen-argon arc discharge with self-heated hollow cathode is investigated. plasma composition was analyzed optical emission spectroscopy. TiSiCN coatings thickness up to 10 microns hardness 30 GPa were obtained 1.5 hours at tempera...

Augmented Reality (AR) and Mixed (MR) have been two of the most explosive research topics in last few years. Head-Mounted Devices (HMDs) are essential intermediums for using AR MR technology, playing an important role progress these areas. Behavioral with users is one way evaluating technical effectiveness HMDs. In addition, technology dependent upon virtual interactions real environment. Thus,...

The objective of the study was to evaluate the feasibility of a UK-based real-time service to improve the diagnosis and management of lymphoproliferative disorders (LPDs) in Ghana. Adult patients reporting to hospital with a suspected LPD, during a 1 year period, were prospectively enrolled. Bone marrow and/or lymph node biopsies were posted to the Haematology Malignancy Diagnostic Service (HMD...

Recent advances in cooperative chemistry have shown the enormous potential of main group heterobimetallic complexes for functionalisation aromatic molecules. Going beyond metal chemistry, here we provide an overview on synthesis, structure and reactivity bimetallic which combine alkali-metal (AM= Li, Na) with a divalent earth-abundant transition (M= Mn, Fe, Co, Ni), containing utility silyl ami...

Alkaline-earth metalation of dimesitylphosphane oxide Mes2P(O)H (1) in ethereal solvents with dialkylmagnesium and alkylmagnesium bromide as well the homoleptic bis(trimethylsilyl)amides calcium, strontium, barium yields [(L)MgR(μ-OPMes2)]2 (L/R=thf/Et (2-Et), Et2O/Br (2-Br)), [(thf)3Ca(hmds)(OPMes2)] (3-hmds), [(thf)3Mg(OPMes2)2] (2-thf) [(thf)4Ae(OPMes2)2] (Ae=Ca (3-thf), Sr (4-thf), Ba (5-th...

Concerns about potentially harmful effects on the visual system due to the use of head mounted displays (HMDs) in general, and stereoscopic systems in particular, have been raised in the literature. Most of the concerns were based on studies measuring visual function changes following short-term use of HMDs. This study measured functional changes in binocular vision, accommodation, and resoluti...

Three experiments examined the influence of field of view and binocular viewing restrictions on absolute distance perception in the real world. Previous work has found that visually directed walking tasks reveal accurate distance estimations in full-cue, real world environments to distances of about 20 meters. In contrast, the same tasks in virtual environments using headmounted displays (HMDs)...
