Research on digital platform evolution is largely focused on how platform-owners leverage boundary resources to facilitate and control contributions from external developers to extend the functional diversity and scope of a digital device. However, our knowledge of the digital platforms that carve out their existence exclusively in the service layer of industry architectures, i.e. without propr...

Source camera linking, i.e., establishing whether or not the images of interest are taken by the same camera without the camera and its digital fingerprint in the investigator’s possession, is an important aspect of image forensics. Sensor pattern noises (SPNs), extracted from digital images as device fingerprints, have been proved as an effective way for digital device identification and have ...

We present a continuous-flow droplet-based digital Enzyme-Linked Oligonucleotide Hybridization Assay (droplet digital ELOHA) for sensitive detection and absolute quantification of RNA molecules. Droplet digital ELOHA incorporates direct hybridization and single enzyme reaction via the formation of single probe-RNA-probe (enzyme) complex on magnetic beads. It enables RNA detection without revers...

We describe in this paper an experimental setting for browsing and reading simultaneously multiple digital documents. An hemispherical visualization device is used to immerge the reader into 3D representations of digital collections.

Connecting and information transfer between the increasing number of personal and shared digital devices in our environment – phones, tablets, and large surfaces – is tedious. One has to know which devices can communicate, what information they contain, and how information can be exchanged. Inspired by Proxemic Interactions, we introduce novel interaction techniques that allow people to natural...

Mountainous river beds-generally consist of gravel particles that the precise description of such bed is not only important hydraulically, but also it has great environmental significance. The accurate estimation of bed roughness gives us valuable information to make reliable hydraulic models of flow in river with rigorous bed form. This study discuses about the accuracy of the Kinect device in...

introdouction: the mapping of ghost images of the maxilla and the nasal cavity, which are complex structures, is very important. the position of objects that create a ghost image can differ when using various devices. the purpose of this investigation was to study the mapping of ghost images of the maxilla and the nasal cavity using a cranex d digital panoramic machine. materials and methods: t...

As digital technologies develop and change, so do the ways these tools are integrated into classrooms. In particular, as mobile digital technologies become ubiquitous there is a need to investigate how teachers engage with these tools—both personally and professionally. Research has consistently shown that teachers’ underlying beliefs and attitudes (particularly their self-efficacy beliefs) are...

PURPOSE The aim of this study is to present the development of a new technique to obtain 3D models using photogrammetry by a mobile device and free software, as a method for making digital facial impressions of patients with maxillofacial defects for the final purpose of 3D printing of facial prostheses. METHODS With the use of a mobile device, free software and a photo capture protocol, 2D c...
