In this paper we propose a new space diversity scheme for broadband PLC systems using orthogonal space-time block coding (OSTBC) transmission combined with single-carrier frequency-domain equalization (SC-FDE). To apply this diversity technique to PLC channels, we first propose a new technique for combining SC-FDE with OSTBCs applicable to all dispersive multipath channels impaired by impulsive...

Cues from social partners trigger the activation of socially responsive neuromodulatory systems, priming brain regions including sensory systems to process these cues appropriately. The fidelity with which neuromodulators reflect the qualities of ongoing social interactions in sensory regions is unclear. We addressed this issue by using voltammetry to monitor serotonergic fluctuations in an aud...

Supported under the NSF Special Projects in Communication and Networking, Ohio State University researchers in both the wireless communications and networking areas are working toward achieving signiicant gains in wireless system performance by leveraging an existing and functioning wireless modem testbed. The narrow-band wireless modem testbed is expected to support both real-time (bus locatio...

We present a theoretical investigation of high-order harmonic generation in a chirped two-colour laser field, which is synthesized by an 800 nm fundamental chirped pulse and a 1200 nm subharmonic chirped pulse. With the introduction of a polarization angle, both the harmonic cutoff is significantly extended and the spectrum intensity is effectively enhanced compared with the orthogonally polari...

Bovine milk is a complex colloidal liquid exhibiting a multi-scaled structure. It is of particular importance, both commercially and scientifically, to investigate both its dynamic and structural properties. In the current study we have employed the broadband dielectric spectroscopy (BDS) technique in the frequency range of 10(-1)-10(6)Hz and the temperature range of 176-230 K in order to exami...

and informatics, various technologies and tools for providing teleconferencing via Internet became available for real-time interaction. In the article by Lee et al.,1 a bidirectional transmission system with digital video transport system (DVTS) and Korea Advanced Research Network (KOREN) was used for two multicenter live endoscopy demonstrations in South Korea. DVTS enables transmission of dig...

This work describes a prototype to convert a conventional pulse oximeter into a wireless device. Samples have been taken from a commercial Nellcor DS-100A probe using an FPGA. This programmable device is integrated with an XBee wireless modem; using ZigBee protocol, data is sent through the wireless network to a central server. The system generates alarms to the medical staff when vital signals...

A variety of studies have focused on the effect of competition in broadband markets on increasing broadband penetration rates. Few studies however have focused on the extent to which competition also results in innovation in the marketplace, as demonstrated by increased broadband speeds, and other improvements that provide value to broadband users. This paper considers the effectiveness of mark...

Communication and co-operation processes in healthcare and welfare require the involvement of all parties involved, including health professionals as well as patients. Generally, professionals can and will easily communicate via trusted health networks. To enforce both communication and co-operation between professionals and patients and to guarantee the required degree of involvement of patien...
