An efficient instance hiding scheme
( Association for Computing Machinery , 2016 , Conference Paper)Delegating computation, which is applicable to many practical contexts such as cloud computing or pay-TV system, concerns the task where a computationally weak client wants to securely compute a very complex function f on ... -
An efficient inverse short-time Fourier transform algorithm for improved signal reconstruction by time-frequency synthesis: Optimality and computational issues
( Elsevier Inc. , 2017 , Article)This paper presents an improved signal reconstruction method based on a new inverse short-time Fourier transform (ISTFT) estimator. The main challenge addressed in this study is to design a more computationally efficient ... -
An efficient LoRa-based smart agriculture management and monitoring system using wireless sensor networks
( Taylor and Francis Ltd. , 2021 , Article)The objective of this paper is to build up a LoRa-based smart agricultural management and monitoring system using Wireless Sensor Networks (WSNs) in rural areas, in order to replace the current technology of the agricultural ... -
An efficient model checker based on theaxiomatization of Propositional Temporal Logic in rewriting logic
( IEEE , 2003 , Conference Paper)In this paper, we propose an efficient Model Checker for the Propositional Temporal Logic denoted by PTL. This logic is hown to be well suited to verify electronic circuits and reactive systems. A typical verification ... -
An Efficient Phase I Analysis of Linear Profiles with Application in Photo-Voltaic System
( Springer Verlag , 2019 , Article)In many manufacturing industries, quality of an item depends on different characteristics and their relationship may be modeled by profiles. For instance, in photo-voltaic (PV) system, output voltage is dependent on the ... -
An efficient PPG Compression Technique for Wearable Health Devices
(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 efficient secure data compression technique based on chaos and adaptive Huffman coding
( Springer , 2021 , Article)Data stored in physical storage or transferred over a communication channel includes substantial redundancy. Compression techniques cut down the data redundancy to reduce space and communication time. Nevertheless, compression ... -
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 ... -
