Variable speed drive (VSD) technology applied to HVAC systems for energy saving: an experimental investigation

Energy Procedia, 2018
Variable speed drive (VSD) technology can be introduced in heating, ventilation and air conditioning (HVAC) systems, normally sized for peak load conditions, to match actual load requirements. The paper presents a detailed assessment of the impact of the

Reed solomon inner-convolutional outer concatenated code with error-erasure decoding for narrowband and broadband power line communications [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2017
A novel concatenated coding system for both narrowband and broadband power line communications (NB-PLC and BB-PLC) is proposed. The order of the inner and the outer codes switches from the G3-PLC standard and the interleaver is eliminated.

Characterization of circulating microRNA expression in patients with a ventricular septal defect. [PDF]

PLoS ONE, 2014
Ventricular septal defect (VSD), one of the most common types of congenital heart disease (CHD), results from a combination of environmental and genetic factors. Recent studies demonstrated that microRNAs (miRNAs) are involved in development of CHD. This

Experimental demonstration of building and operating QoS-aware survivable vSD-EONs with transparent resiliency.

Optics Express, 2017
Software-defined elastic optical networks (SD-EONs) provide operators more flexibility to customize their optical infrastructures dynamically. By leveraging infrastructure-as-a-service (IaaS), virtual SD-EONs (vSD-EONs) can be realized to further enhance
