We propose using power-over-fiber (PoF) in some part of future 5G cellular solutions based on radio access networks considering currently installed front-haul with single mode fiber to optically power communication systems for new (NR) data transmission. Simulations addressing design parameters are presented. Radio-over-fiber (RoF) transmission over (SMF) is experimentally implemented and teste...

Although the segmental properties of Kyungsang Korean have been known to be distinct from those of standard Seoul Korean, the increased influence of Seoul Korean on the regional variety casts doubt on the homogeneity of the dialect. The current study investigated whether the acoustic properties of the vowels and fricatives in Kyungsang Korean are retained by both younger and older generations t...

Positive- and negative-reinforcement-based procedures typically have targeted acceptance for children with severe food refusal; however, these procedures do not always result in successful swallowing. Once acceptance is achieved, some children expel the food repeatedly or pack (hold or pocket) it in their mouths for extended periods of time. This study evaluated the effects of using food redist...

The study of the Greek language is argued here to be of relevance to Slavic studies and Slavic linguistics in several ways. After a brief presentation of some of the more important connections between Greek and the Slavic linguistic world, the focus is turned to one in particular that has not commanded the attention it might, namely the fact that Greek has historically been spoken and continues...

Wave theory originated in quantum physics as an elegant way to describe the properties and movement of light, sound, atoms and, eventually, all forms of energy. The underlying thesis migrated to the world of finance in postulations such as the Elliott Wave Theory, which holds that there are repeated, predictable patterns in market pricing. Most recently, social scientists have been applying wav...

An analysis of dynamic markings in 24 paired preludes in major and minor keys shows that the minor mode is associated with a generally lower dynamic level than the major mode. The results are consistent with observations in speech prosody, where sad or depressed speakers show reduced acoustic energy compared with normal or happy speakers. Submitted 2007 October 15; accepted 2008 January 6.

The goal of this paper is to discuss how adaptive search systems should be evaluated. We argue that a state-of-the art evaluation of adaptive search systems should follow a “layered evaluation” approach. To support and explain this argument we describe how layered approach was applied to evaluation of adaptive search component of Knowledge Sea II system that is powered by a social navigation su...
