An observer, when shown only the 2D projection of a rotating object not directly visible to her, perceives the projection as being a 3D object with depth attributes. Wallach and O’Connell [1] named this interesting phenomenon as the ‘Kinetic Depth Effect’ and conducted a detailed study of its origin and its characteristics. In [1], they describe a simple experiment wherein a subject is shown th...

This paper introduces a novel approach towards direct interaction with large display systems. Monocular computer vision is utilised to avoid restraints imposed by input devices. Tracking the user’s head and determining the view frustum in real-time is one of the key processes in our proposed human-computer interaction system. We also proposed using a view frustum to model the user’s interaction...

In the human behavior analysis, the Visual Focus Of Attention (VFOA) of a person is a very important cue. Its detection is difficult, though, especially in a unconstrained and crowded environment, typical of video surveillance scenarios. In this paper, we estimate the VFOA by defining the Subjective View Frustum, which approximates the visual field of a person in a 3D representation of the scen...

Chlorine dioxide (ClO2) inactivation experiments were conducted with adenovirus type 40 (AD40) and feline calicivirus (FCV). Experiments were carried out in buffered, disinfectant demand-free water under high- and low-pH and -temperature conditions. Ct values (the concentration of ClO2 multiplied by contact time with the virus) were calculated directly from bench-scale experiments and from appl...

This paper compares the manufacturing and refueling costs of a Fuel-Cell Vehicle (FCV) and a Battery Electric Vehicle (BEV) using an automobile model reflecting the largest segment of light-duty vehicles. We use results from widely-cited government studies to compare the manufacturing and refueling costs of a BEV and a FCV capable of delivering 135 horsepower and driving approximately 300 miles...

The prevalence of feline herpesvirus-1 (FHV-1), feline calicivirus (FCV), and Chlamydophila (C.) felis was studied in cats of an animal shelter in Korea. Total 78 cats without ocular and upper respiratory tract disease were examined. Specimens were obtained from ocular conjunctiva and oropharynx. Using multiplex polymerase chain reaction (PCR) and reverse transcription PCR, three pathogens were...

In this paper, we present and examine range detection approach for view frustum culling that effectively speed-up the interactive virtual heritage project namely Ancient Malacca Virtual Walkthrough. The Ancient Malacca Virtual Walkthrough is a project that focuses on the modeling and visualization of Malacca city in 15th century. Traditional six plane view frustum culling approach use the plane...
