A Fatigue Measuring Protocol for Wireless Body Area Sensor Networks
(
Springer New York LLC
, 2015 , Article)
As players and soldiers preform strenuous exercises and do difficult and tiring duties, they are usually the common victims of muscular fatigue. Keeping this in mind, we propose FAtigue MEasurement (FAME) protocol for ...
Politeness on Facebook: The case of Greek birthday wishes
(
John Benjamins Publishing
, 2015 , Article)
Facebook forms one of the most widely used online social networks, through which people manage their communication with diverse contacts or 'friends', ranging from members of the family and schoolmates to work colleagues ...
An interdisciplinary specialist team leads to improved diagnostics and treatment for paediatric patients with vascular anomalies
(
John Wiley & Sons Ltd.
, 2015 , Article)
Aim Patients with vascular anomalies are often misdiagnosed, leading to delayed or improper treatment. The aim of this study was to evaluate the impact of an interdisciplinary team on the diagnosis and treatment of ...
Ionic Liquids in Bulk and at an Interface
(
John Wiley & Sons, Inc
, 2015 , Book chapter)
In the present chapter, we describe different types of investigation carried out by research groups based at CQE/IST/UTL and ITQB/UNL and their ramifications in terms of surface science. Most of the work is focused on the ...
Modelling the degradation of vibration characteristics of reinforced concrete beams due to flexural damage
(
John Wiley & Sons, Ltd.
, 2015 , Article)
This paper presents an improved crack model incorporating non-linearity of flexural damage in concrete to reproduce changes in vibration properties of cracked reinforced concrete beams. A reinforced concrete beam model ...
To Relay or Not To Relay in Cognitive Radio Sensor Networks
(
IEEE
, 2014 , Article)
A recent investigation on MAC layer in cognitive radio networks proposed the primary packet relaying by the secondary node maintaining an extra queue used for this particular addable functionality. Nevertheless, relaying ...
Exact SINR analysis of OFDM systems under joint Tx/RX I/Q imbalance
(
IEEE
, 2013 , Conference Paper)
The direct-conversion architecture used for Orthogonal Frequency Division Multiplexing (OFDM) systems suffers from intercarrier interference (ICI) between image subcarriers in each OFDM symbol due to I/Q imbalance between ...
Maximizing Energy Efficiency in Multiple Access Channels by Exploiting Packet Dropping and Transmitter Buffering
(
IEEE
, 2015 , Article)
Quality of service (QoS) for a network is characterized in terms of various parameters specifying packet delay and loss tolerance requirements for the application. The unpredictable nature of the wireless channel demands ...
Implementation and Analysis of Reward Functions under Different Traffic Models for Distributed DSA Systems
(
IEEE
, 2015 , Article)
In this paper, we implement and analyze a resource allocation protocol for distributed dynamic spectrum allocation (DSA) systems. The DSA protocol is a learning-based protocol that allows secondary users (SU) to exploit ...
Beamforming OFDM Performance under Joint Phase Noise and I/Q Imbalance
(
IEEE
, 2015 , Article)
Phase noise (PHN) and in-phase/quadrature (I/Q) imbalance are two major RF impairments in direct-conversion wireless transceivers. Beamforming and orthogonal frequency division multiplexing (OFDM) schemes have been adopted ...
