In this paper, we survey the state of the art of the secure key exchange method that is secured by the laws of classical statistical physics, and involves the Kirchhoff's law and the generalized Johnson noise equation, too. We discuss the major characteristics and advantages of these schemes especially in comparison with quantum encryption, and analyze some of the technical challenges of its im...

Teleconsulting and Teleconferencing is nowadays a strict need for patient follow-up or for medical second opinion. The growing of this kind of techniques for teleconsulting needs an effective way to achieve a fast communication on non-dedicated connection lines. Moreover another prerequisite for this kind of activities is the conformance to DICOM that is the de facto standard for medical image ...

The actual idea of a telephony structure shows a Private Automatic Branch Exchange (PABX) directly controlling a whole communication system. Ringing and caller identification signals, voltage setting for the phone sets among other important parameters all are transmitted using twisted pair cables that have to be installed and distributed along the building. The use of existing indoor power line...

We present a general framework for designing optimal transmit spectra for symmetric bit-rate Digital Subscriber Line (DSL) services, in particular HDSL2. Using the channel and interference transfer functions and SNR estimates, we set up and solve an optimization problem to maximize the capacity. Sizable gains in performance margins (or bit rates) result. Furthermore, by design, the spectra are ...

The history of ethno-national conflict on the ethnically divided Mediterranean island of Cyprus has decisively marked the communication process between the major stakeholders in the conflict, but most of all, and in a profound way, between the two Cypriot communities, namely, between Greek Cypriots (G/Cs) and Turkish Cypriots (T/Cs). The so-called Green Line, which ethnically divides the capita...

The administration of vesicant drugs involves nurses and physicians as stakeholders in providing safe patient care. Improving communication often is the first step to increasing the awareness and problem-solving for the patient care team.
