A problem-oriented approach to represent and manage knowledge in PBL
(
Asia-Pacific Society for Computers in Education
, 2015 , Conference Paper)
In traditional subject-based learning knowledge is well-structured and prepared in advance by the teachers before transferring in the form of a lecture presentation. However, the knowledge learned in problem-based learning ...
Micro-Doppler characteristics of elderly gait patterns with walking AIDS
(
SPIE
, 2015 , Conference Paper)
In this paper, we analyze the micro-Doppler signatures of elderly gait patterns in the presence of walking AIDS using radars. The signatures are based on real data experiments conducted in a laboratory environment using ...
Space vector pulse width modulation techniques for a five-phase impedeance source and quazi impedeance source inverters
(
IEEE
, 2015 , Conference Paper)
Impedance source inverter (ZSI) and its variant quasi impedance source inverter (qZSI) are single stage inverters that transform dc to ac and boost the source voltage at the same time. These topologies have attracted great ...
Effect of bone density on the compressive mechanical properties of bovine trabecular bone
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
The density of bone is subject to change due to natural causes or bone abnormalities and disorders such as osteopenia, osteomalacia and osteoporosis. One of the most concerning attributes of osteoporosis is its non-expressive ...
Energy-efficient cooperative relaying protocol for full-duplex cognitive radio users and delay-aware primary users
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper considers a network in which a primary user (PU) may cooperate with a cognitive radio (CR) user for transmission of its data packets. The PU is assumed to be a buffered terminal operating in a time-slotted ...
Histogram-based thresholding in discrete wavelet transform for partial discharge signal denoising
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
White noise is a major interference source that affects the partial discharge (PD) signal detection and recognition. Wavelet shrinkage denoising methods can efficiently reject the white noise embedded in the PD signal ...
The elasticity of patent activities with respect to R&D-performing sectors: An empirical study on high-income OECD countries
(
Inderscience Publishers
, 2015 , Conference Paper)
This study examines the impact of R&D performing sectors, business, higher education, and government, on patent activities in 14 high income OECD countries using dynamic panel data model. In addition, the paper investigates ...
Electrospun PET-PU scaffolds for vascular tissue engineering
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
The incidence of cardiovascular diseases (CVD) is projected to continuously increase in the coming decades, with a colossal associated cost of treatment. In the US alone, 83.6 million people are estimated to have one or ...
A nine-arm modular multilevel converter (9A-MMC) for six-phase medium voltage motor drives
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
Dual three-phase (asymmetrical six-phase) induction motors have received significant attention in high power medium voltage drive applications. Typically, two three-phase voltage source converters are needed to feed such ...
Interference Aware Inverse EEDBR protocol for Underwater WSNs
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
The unique characteristics of Underwater Wireless Sensor Networks (UWSNs) attracted the research community to explore different aspects of these networks. Routing is one of the most important and challenging function in ...
