Throughput maximization via adjusting packet size of a buffered cognitive radio user
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
In this paper, we investigate a cognitive scenario with one secondary user and one primary user. Users are assumed to be buffered terminals. Each user has certain arrival rate with certain packet size. We propose a scheme ...
Solar thermochemical conversion of CO2 into synthetic fuels via ferrite based redox reactions
(
AIChE
, 2014 , Conference Paper)
In this contribution, we report the synthesis NiFe2O4 and CoFe2O4 redox materials via sol-gel method. For the synthesis of these materials via sol-gel approach, the Ni, Co, and Fe precursors were first dissolved in ethanol ...
Transparent conducting electrodes based on thin, ultra-long Copper nanowires and graphene nano-composites
(
SPIE
, 2014 , Conference Paper)
High aspect-ratio ultra-long (> 70 ?m) and thin (< 50 nm) copper nanowires (Cu-NW) were synthesized in large quantities using a solution-based approach. The nanowires, along with reduced graphene-oxide sheets, were coated ...
Conservation And Development Of Cultural Heritage In Doha
(
Hamad bin Khalifa University Press (HBKU Press)
, 2014 , Conference Paper)
Throughout the world, many urban designers and architects have been working toward the protection, preservation and enhancement of urban heritage in order to increase its usefulness as well as preserve the cities' cultural ...
Closed-loop control of anesthesia and mean arterial pressure using reinforcement learning
(
IEEE
, 2014 , Conference Paper)
General anesthesia is required for patients undergoing surgery as well as for some patients in the intensive care units with acute respiratory distress syndrome. How-ever, most anesthetics affect cardiac and respiratory ...
Cooperative access in cognitive radio networks: Stable throughput and delay tradeoffs
(
IEEE
, 2014 , Conference Paper)
In this paper, we study and analyze fundamental throughput-delay tradeoffs in cooperative multiple access for cognitive radio systems. We focus on the class of randomized cooperative policies, whereby the secondary user ...
Discrete time domain analysis and optimal design of stationary frame AC current controllers with active damped LCL Filter for high power applications
(
IEEE Computer Society
, 2014 , Conference Paper)
Due to the large variety of renewable power sources, power electronics play an important role in energy conversion. Different power converter topologies are used to interface distributed power generation systems (DPGS) ...
MIMO vehicle to vehicle channels: An experimental study
(
IEEE
, 2014 , Conference Paper)
In this paper, a platform for measuring the impulse response of wireless multiple-input-multiple-output (MIMO) vehicle-to-vehicle (V2V) channels is presented. The platform is developed using Rice University Wireless ...
Phase noise mitigation in OFDMA uplink
(
IEEE
, 2014 , Conference Paper)
This paper addresses the problem of the phase noise induced spectral spread in an OFDMA uplink scenario. Accompanied with power differences between the users at the receiver in a multiuser case, the phase noise induced ...
Traction system with on-board inductive power transfer
(
Institution of Engineering and Technology
, 2014 , Conference Paper)
In traction applications based on long primary and short secondary type, contactless electrical energy transmission can offer distinct advantages over the conventional energy transmission based on catenary system to provide ...
