Computer Graphics (CG) and Virtual Reality (VR) are two of the most interesting research fields in Computer Science. In this paper we present an application of CG and VR in arts, tourist promotion and cultural heritage. We propose a technique able to simulate the Saint Mary of the Mount staircase, a magnificent staircase in Caltagirone, a beautiful baroque town in Sicily (Italy). Our system is ...

Auditory brainstem response (ABR) peak measures were compared for a custom ear canal electrode and traditional mastoid and ear lobe reference electrode sites with the assumption that the ear canal electrode would yield larger Wave I amplitudes. In this study, Waves I, III, and V latencies and amplitudes were measured and compared in twenty participants between the ages of 18 and 50, with partic...

The syntactic wellformedness constraints of XML (opening and closing tags nest properly) imply that XML processors face the challenge to efficiently handle data that takes the shape of ordered, unranked trees. Although RDBMSs have originally been designed to manage table-shaped data, we propose their use as XML and XPath processors. In our setup, the database system employs a relational XML doc...

One of the key research interests in the area of Constraint Satisfaction Problem (CSP) is to identify tractable classes of constraints and develop efficient solutions for them. In this paper, we introduce generalized staircase (GS) constraints which is an important generalization of one such tractable class found in the literature, namely, staircase constraints. GS constraints are of two kinds,...

The behavior of isolation-reared mice has not yet been studied in the staircase test. The present study examined the effects of anxiolytic or anxiogenic agents and isolation rearing on the behavior of ddY (outbred) strain mice in the staircase test. Diazepam and phenobarbital increased the number of steps climbed, but did not affect rearing behavior in group-reared mice. FG-7142, a benzodiazepi...

Many interesting combinatorial objects are enumerated by the k-Catalan numbers, one possible generalization of the Catalan numbers. We will present a new combinatorial object that is enumerated by the k-Catalan numbers, staircase tilings. We give a bijection between staircase tilings and k-good paths, and between k-good paths and k-ary trees. In addition, we enumerate k-ary paths according to D...

Large variability in thresholds to sensory stimuli is observed frequently even in healthy populations. Much of this variability is attributed to genetics and day-to-day fluctuation in sensitivity. However, false positives are also contributing to the variability seen in these tests. In this study, random number generation was used to simulate responses in threshold methods using different "stop...
