A Novel Modified Switched Inductor Boost Converter with Reduced Switch Voltage Stress
( Institute of Electrical and Electronics Engineers Inc. , 2021 , Article)Recently, switched inductor (SI) and switched capacitor techniques in dc-dc converter are recommended to achieve high voltage by using the principle of parallel charging and series discharging of reactive elements. It is ... -
Non-Isolated DC-DC Power Converter with High Gain and Inverting Capability
( Institute of Electrical and Electronics Engineers Inc. , 2021 , Article)As the voltage gain of converter increases with the same ratio, the current gain also increases, this increase in current gains will affect the size of the input and the output capacitor. To reduce the ripple in the input ... -
A social-ecological perspective for emerging cities: The case of Corniche promenade, “urban majlis” of Doha
( EnPress Publisher, LLC , 2022 , Article)In the past decade, the capital city of Doha of the State of Qatar has experienced rapid urban expansion and other changes due to globalization, which has caused (i) the loss of a compact urban pattern, (ii) landscape ... -
Melt Processing and Properties of Polyamide 6/Graphene Nanoplatelet Composites
( ICCCM , 2015 , Conference Paper)In this paper, the processing and characterization of Polyamide 6 (PA6) / graphite nanoplatelets (GNPs) composites is reported. PA6/GNPs composites were prepared by melt-mixing using an industrial, co-rotating, intermeshing, ... -
Melt processing and characterisation of polyamide 6/graphene nanoplatelet composites
( Royal Society of Chemistry , 2015 , Article)Graphene, due to its outstanding properties, has become the topic of much research activity in recent years. Much of that work has been on a laboratory scale however, if we are to introduce graphene into real product ... -
Processing and characterization of polyethylene-based composites
( Taylor & Francis , 2015 , Article)Thermoplastic matrix polymer composites have gained commercial success in the semistructural and structural applications. Polyethylene (PE) is one of the most versatile and widely used thermoplastics in the world because ... -
Towards a knowledge-hub destination: analysis and recommendation for implementing TOD for Qatar national library metro station
( Springer , 2023 , Article)During the past two decades, Qatar, a developing country, has invested heavily in infrastructure development to address several challenges caused by the rapid urbanization. Qatar has made a significant step toward its urban ... -
Improved flexible, controlled dielectric constant material from recycled LDPE polymer composites
( Springer Nature , 2016 , Article)In this study, recycled low density polyethylene (RLDPE) is developed with the addition of aluminum oxide (Al2O3) to have new polymer composites. The following wt% were used of the filler (1, 4 and 6 wt%). Tensile properties, ... -
Biotechnological production process and life cycle assessment of graphene
( Hindawi , 2017 , Article)The aim of this study is to compare the graphene produced using a biotechnological method (Escherichia coli) with the graphene produced by Hummers' method (a chemical method) and to study the effect on the energy consumption ... -
Rethinking urbanism in Doha : The Qatar National Museum transit-oriented development
( Henry Stewart Publications LLP , 2021 , Article)The urban environment of Doha has witnessed a remarkable transformation during the past few decades, which has been triggered by economic growth due to oil and gas revenues. Doha has attracted foreign investment to participate ... -
Strategies for the urban regeneration of the Museum of Islamic Art Park in Doha, Qatar
( Henry Stewart Publications LLP , 2023 , Article)Doha has witnessed rapid urban growth, an increasing population rate and a greater reliance on cars as the primary mode of transport. This has caused social and environmental problems related to a sprawling urban pattern, ... -
An urban regeneration-placemaking strategy for the Qatar National Museum and Souq Waqif’s transit-oriented development in Doha, State of Qatar
( Henry Stewart Publications LLP , 2023 , Article)In the past 20 years, the State of Qatar has undergone rapid urban growth. Doha, the capital city, has capitalised on large-scale urban and infrastructural projects to strengthen and diversify its economy. The transport ... -
Transit‐Oriented Development and Livability: The Case of the Najma and Al Mansoura Neighborhoods in Doha, Qatar
( Cogitatio Press , 2022 , Article)Since the 1970s, Qatar’s rapid urban growth has resulted in a segregated and poorly connected urban form, particularly in the country’s capital, Doha. Although the recent opening of the Doha Metro has begun to mitigate ... -
Sustainable Status Assessment of the Transit-Oriented Development in Doha’s Education City
( MDPI , 2023 , Article)Doha, the capital of the State of Qatar, has seen rapid growth in recent years, resulting in challenges that can be addressed through sustainable urban design strategies. Such approaches, including Transit-Oriented ... -
Melt processing and properties of linear low density polyethylene-graphene nanoplatelet composites
( Elsevier , 2016 , Article)Composites of Linear Low Density Polyethylene (LLDPE) and Graphene Nanoplatelets (GNPs) were processed using a twin screw extruder under different extrusion conditions. The effects of screw speed, feeder speed and GNP ... -
Improved Nonparametric Control Chart Based on Ranked Set Sampling with Application of Chemical Data Modelling
( Hindawi Limited , 2022 , Article)e statistical performance of parametric control charts is questionable when the underlying process does not follow any speci ed probability distribution. Nonparametric control charts are the best substitute for this ... -
A new hwma dispersion control chart with an application to wind farm data
( MDPI AG , 2020 , Article)Recently, a homogeneously weighted moving average (HWMA) chart has been suggested for the efficient detection of small shifts in the process mean. In this study, we have proposed a new one-sided HWMA chart to effectively ... -
