(2021 , Master Thesis)Photoplethysmography is a simple, widely used, low-cost technique to acquire important diagnostic information for assessing significant physiological parameters of the human body based on the amount of light reflected from ... -
An efficient reduced complexity PAPR reduction approach for 3GPP LTE system
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)In wideband communication systems, Multi-Input Multi-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) has been proposed as an efficient technique to enhance the link reliability and the spectral efficiency. ... -
An EMG signal processing system for control of an ankle-foot orthosis
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)This paper presents an electromyographic (EMG)based digital processing system for estimating foot direction of motion and force exerted from muscles of the human lower leg. This information can be used in the control ... -
An empirical assessment on the transportation sustainability indicators and their impact on economic productivity
( IEOM Society , 2020 , Conference Paper)Sustainable transportation has been traditionally acknowledged as an accelerating factor in achieving economic productivity. This paper attempts to frame a methodology to study the sustainability of the transportation ... -
An empirical correlation-based model to predict solid-fluid phase equilibria and phase separation of the ternary system CH4-CO2-H2S
( Elsevier , 2021 , Article)To cover the expected increased demand for natural gas, energy industry has to exploit sour gas reserves located around the world. However, acid gases have to be removed before the natural gas produced from these fields ... -
An empirical determination of the whole-life cost of FO-based open-loop wastewater reclamation technologies
( Elsevier Ltd , 2019 , Article)Over the past 5–10 years it has become apparent that the significant energy benefit provided by forward osmosis (FO) for desalination arises only when direct recovery of the permeate product from the solution used to ... -
An empirical evidence on audit selection and audit rotation: The case of Qatari listed companies
( Inderscience Publishers , 2017 , Article)The primary objective of this research is to examine the current state of audit selection and rotation practised by Qatari listed firms. A questionnaire survey has been used. A number of findings have emerged from the ... -
An empirical examination of moral hazards and adverse selection on PPP projects: A case study of Ghana
( Emerald Group Publishing Ltd. , 2018 , Article)Purpose: Failures of public?private partnership (PPP) projects are often ascribed to the agency problem, which arise under conditions of inadequate and asymmetric information when a principal (the client) hires an agent ... -
