Class-time utilization in business schools in Tunisia
(
Elsevier Ltd
, 2016 , Article)
Tunisian Universities, like many other universities in the developing countries, do not adopt any textbooks and rather rely on classrooms as the main learning resource for the students. This study is concerned with observing ...
Investigation on SVM-Backstepping sensorless control of five-phase open-end winding induction motor based on model reference adaptive system and parameter estimation
(
Elsevier B.V.
, 2019 , Article)
This paper deals with a new control technique applied to five-phase induction motor under open-end stator winding (FPIM-OESW) topology using the backstepping nonlinear control. The main objective is to improve the dynamics ...
Spillovers between food and energy prices and structural breaks
(
Elsevier B.V.
, 2017 , Article)
This paper estimates a bivariate VAR-GARCH(1,1) model to examine linkages between food and energy prices. The adopted framework is suitable to analyse both mean and volatility spillovers, and also allows for possible ...
The cost-effectiveness of a patient centred pressure ulcer prevention care bundle: Findings from the INTACT cluster randomised trial.
(
Elsevier
, 2017 , Article)
Pressure ulcers are serious, avoidable, costly and common adverse outcomes of healthcare. To evaluate the cost-effectiveness of a patient-centred pressure ulcer prevention care bundle compared to standard care. Cost-effectiveness ...
Narcissism, interactivity, community, and online revenge behavior: The moderating role of social presence among Jordanian consumers
(
Elsevier
, 2019 , Article)
This study tests the effect of personal and online characteristics on consumers' desire for revenge and their online revenge intentions. In light of the interactivity and community of social media platforms, it examines ...
On the delay/throughput-security tradeoff in wiretap TDMA networks with buffered nodes
(
IEEE
, 2019 , Article)
In this paper, we investigate the tradeoff between security and throughput and between security and queuing delay in wiretap time-division multiple access (TDMA) networks. We derive a simple relationship, characterized by ...
Decentralized multiuser diversity with opportunistic packet transmission in MIMO wireless sensor networks
(
Elsevier
, 2013 , Article)
In this study, we consider a single-hop wireless sensor network where both the sensor nodes and the controller node have multiple antennas. We focus on single beam opportunistic communication and propose a threshold-based ...
I/Q imbalance in multiple beamforming {OFDM} transceivers: SINR analysis and digital baseband compensation
(
IEEE
, 2013 , Article)
In this paper, we start by investigating the impact of joint transmit-receive I/Q imbalance on the performance of direct-conversion beamforming OFDM transceivers. We derive a new analytical expression for the average ...
A regularization approach to MSE analysis of OFDM under phase noise
(
Elsevier
, 2018 , Article)
Orthogonal frequency division multiplexing (OFDM) is widely used in broadband wireless communications systems because of its high resilience to frequency-selective fading and its low implementation complexity. Phase noise ...
Exploiting Sparsity in Amplify-and-Forward Broadband Multiple Relay Selection
(
IEEE
, 2019 , Article)
Cooperative communication has attracted significant attention in the last decade due to its ability to increase the spatial diversity order with only single-antenna nodes. However, most of the techniques in the literature ...
