Visually Perceived Distance Judgments: Tablet-Based Augmented Reality Versus the Real World
2016
Does visually perceived distance differ when objects are viewed in augmented reality (AR), as opposed to the real world? What are the differences? These questions are theoretically interesting, and the answers are important for the development of many tablet- and phone-based AR applications, including mobile AR navigation systems. This article presents a thorough literature review of distance judgment experimental protocols, and results from several areas of perceptual psychology. In addition to distance judgments of real and virtual objects, this section also discusses previous work in measuring the geometry of virtual picture space and considers how this work might be relevant to tablet A…
Messa a punto di un protocollo sperimentale per la ricerca di Enterovirus in sedimenti marini
2009
In riferimento al Decreto Ministeriale del 24/01/1996, il controllo dei fondali marini utilizzati per il ripascimento dei litorali, costituisce un passo importante per la valutazione della salubrità dell’ambiente marino e dei prodotti ittici da allevamento, con particolare riferimento alla coltivazione di molluschi eduli lamellibranchi. Diversi studi, infatti, hanno dimostrato come i sedimenti, per le loro caratteristiche chimico-fisiche, rappresentano dei “serbatoi” di agenti microbici di varia natura che, da qui possono essere risospesi nelle acque, compromettendo la salubrità dell’ambiente. Poiché i molluschi eduli lamellibranchi sono organismi filtratori e trattengono agenti patogeni ca…
Run duration effects on the hydrodynamic properties of a loam soil estimated by steady-state infiltration methods
2020
Steady-state methods for the analysis of single-ring infiltration data are commonly applied. However, the duration of an infiltrometer experiment is often established quite subjectively based on the assumption that in general infiltration stabilizes rather quickly in the field. For a loam soil, the effect of the duration of a beerkan run on sorptivity, S, and saturated hydraulic conductivity, Ks, was tested by using the BEST (Beerkan Estimation of Soil Transfer parameters)-steady method and SSBI (Steady version of the Simplified method based on a Beerkan Infiltration run) method for data analysis. The standard experiment, based on a total of 15 water volumes each establishing an initial pon…
