Tweet sentiment analysis with pronoun choice reveals online community dynamics in response to crisis events
(
Springer Verlag
, 2017 , Conference Paper)
We describe the emergence of an online community from naturally occurring social media data. Our method uses patterns of word choice in an online social platform to characterize how a community forms in response to adverse ...
Possible effects of emoticon and emoji on sentiment analysis web services of work organisations
(
Inderscience Enterprises Ltd.
, 2019 , Conference Paper)
Work organisations are increasingly interested in using sentiment analysis algorithms to get rapid feedback from microblogging platforms such as Twitter. However, real-life posts can differ from the training data. The ...
Impact of time synchronization error on the mode-shape calculation in wireless sensor networks for structural health monitoring
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
For structural health monitoring (SHM), mode shape calculation is an important task that needs to be performed accurately and reliably. The use of wireless sensor networks (WSNs) for SHM is a very effective and a promising ...
Optimized collaborative spectrum sensing in energy harvesting cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
We study the probability of error optimization problem in collaborative spectrum sensing (CSS) with limited time and energy resources in energy harvesting cognitive radio (CR) networks. The frame structures for sensing and ...
VacoNet: Variable and connected architecture for data center networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Todays data centers may contain tens of thousands of computers with progressively more specialized and expensive equipments. Thus, the research community has proposed various interconnect topologies e.g FatTree, Dcell and ...
On the performance of spectrum sensing based on GLR for full-duplex cognitive radio networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In cognitive radio networks, secondary users (SUs) utilize the unused spectrum slots in the assigned band for the primary users (PUs). Conventional cognitive radio networks operate in half-duplex (HD) mode. Recently, ...
Optimal collaborative energy harvesting spectrum sensing with limited time resource
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
We study a collaborative spectrum sensing (CSS) problem with limited time and energy resources in cognitive radio (CR) network. Time duration of sensing and data transmission, if the spectrum is identified as vacant, are ...
Energy efficient power allocation for carrier aggregation enabled communications systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
The Energy Efficiency (EE) of Carrier Aggregation (CA) enabled communications systems is studied. In more detail, the problem of the optimal power allocation for CA enabled systems exploiting multiple Parallel Frequency ...
Performance analysis of full-duplex multiuser decode-And-forward relay networks with interference management
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
In this paper, a cooperative communications scheme with interference management is proposed for Full-Duplex (FD) multi-user, decode-And-forward (DF) relay networks. The scheme is based on a relay selection method that ...
User-centric network selection in multi-RAT systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Rising numbers of mobile devices and wireless access technologies motivate network operators to leverage spectrum across multiple radio access networks, in order to significantly enhance quality of service as well as network ...
