The provision of adaptive content to mobile wireless devices has increasingly become very pertinent. Mobile smart phones and other wireless device usage is increasing daily with ground breaking technological developments – in design, style, content and micro-chips performance. Transmission of data in such environments requires absolute security to protect the individual and content. Any interfe...

We survey and evaluate popular audio fingerprinting schemes in a common framework with short query probes captured from cell phones. We report and discuss results important for mobile applications: Receiver Operating Characteristic (ROC) performance, size of fingerprints generated compared to size of audio probe, and transmission delay if the fingerprint data were to be transmitted over a wirel...

because of approaches to learning in every place and at any time, ubiquitous learning with knowledge of the context and framework, and due to the development of wireless technologies and sensors, the learning process has changed. mobile learning and ubiquitous learning as models of e-learning that refer to the acquisition of knowledge, attitudes and skills through wireless technologies. the eff...

 In most engineering colleges, giving lectures for 300 or 400 students is a practical necessity. Most lecture theatres are large and when filled up, they're intimidating to the average student and do not invite students to an active participation. They also restrict the teacher's opportunities to interact with the students. In this paper we describe a “proofof-concept” system developed at Oslo...

Quickly changing technologies and intensive uses of radiofrequency electromagnetic field (RF-EMF)‑emitting phones pose a challenge to public health. Mobile phone users and uses and exposures to other wireless transmitting devices (WTDs) have increased in the past few years. We consider that CERENAT, a French national study, provides an important addition to the literature evaluating the use of ...

Authentication and privacy refer to the problems of ensuring that communication takes place only between the right parties without disclosure of information to unauthorized eavesdroppers. Radio communication is highly appealing for the convenience of mobility—the freedom from a fixed location. For this reason, wireless services have been growing rapidly. In 2005, an ITU study found more than 2 ...
