This paper outlines a study into the effects of colocation of haptic and visual sensory modes in VR simulations. The study hypothesis is that co-location of these sensory modes will lead to improved task performance and enhanced sense of presence within a VR environment. Experiments were conducted to evaluate the effect on user performance of co-located haptic feedback. Results show that co-loc...

We investigate the one-parameter Calabi-Yau models and identify families of D5-branes which are associated to lines embedded in these manifolds. The moduli spaces are given by sets of Riemann curves, which form a web whose intersection points are described by permutation branes. We arrive at a geometric interpretation for bulk-boundary correlators as holomorphic differentials on the moduli spac...

This paper summarises the results of several studies of individual differences among users navigating in virtual environments. These differences relate to performance of navigational tasks, and the degree of sense of presence experienced by the users. The individual differences addressed in this paper refer primarily to personality and demographic factors. The possibility of improving the desig...

Data mining techniques are a very important tool for extracting useful knowledge from databases. Recently, some approaches have been developed for mining novel kinds of useful information, such as anomalous rules. These kinds of rules are a good technique for the recognition of normal and anomalous behaviour, that can be of interest in several area domains such as security systems, financial da...

Introduction: The pectoralis minor muscle originates from third to fifth ribs of the chest wall and inserts at the medial side of the coracoid process of Scapula. It contributes to the abduction of the scapulothoracic joint and downward movement of the shoulder. The anomalous insertion of pectoralis minor beyond the coracoid process is known since the 19th century. Aim of the study: To report ...

Background: Previous results showed that quantitative changes in behavioural accuracies by rats that sustained a “mild” closed head injury were moderately correlated with the total areas (numbers) of anomalous neuronal soma within regions below the impact. Method: Water maze behavioural measures within one day or two months after a single impact of mechanical force over the right dorsal skull, ...

SEVERAL authors (Lyle and Foley, 1955; Naylor, Shannon, and Stanworth, 1956; Naylor and Stanworth, 1959; Guzzinati and Salvi, 1957; Pasino, Maraini, and Santori, 1963) have observed the absence of a stereoscopic perception of depth in early convergent strabismus with anomalous retinal correspondence. Even in patients with an extremely small fixed ocular deviation and harmonious anomalous retina...
