( American Scientific Publishers , 2017 , Article)In this paper, we show that the (2+1)-dimensional coupled Burgers system with time variable coefficients which arise in engineering, chemistry, chemical physics, plasma physics, complex physics and phenomena gives multiple ... -
A New Non-Isolated High-Gain Single-Switch DC–DC Converter Topology with a Continuous Input Current
( MDPI , 2022 , Article)An ultra-high step-up, non-isolated DC–DC converter with a continuous input current was developed as a result of this research. This converter’s architecture consists of a voltage multiplier cell (VMC), a positive output ... -
New nonlinear estimators of the gravity equation
( Elsevier , 2020 , Article)The gravity model of international trade is often applied by economists to explain bilateral trade between countries. Nevertheless, some estimation practices have been subject to criticism, namely how zero trade values and ... -
A new normalized Deadbeat control for grid connected distributed generation systems
( IEEE , 2013 , Conference Paper)This paper proposes a newly designed Real Time Digital Feedback Controller for a grid connected PV system. A multilevel Flying Capacitors Inverter (FCI) along with inductor and step-up transformer is used as an interface ... -
A new One Health Framework in Qatar for future emerging and re-emerging zoonotic diseases preparedness and response
( Elsevier , 2023 , Article)One Health is increasingly recognized as an optimal approach to address the global risk of health threats originating at the human, animal, and ecosystem interface, and their impact. Qatar has successfully practiced One ... -
A New One-Step Iterative Process for Common Fixed Points in Banach Spaces
( Hindawi Publishing Corporation , 2008 , Article)We introduce a new one-step iterative process and use it to approximate the common fixed points of two asymptotically nonexpansive mappings through some weak and strong convergence theorems. Our process is computationally ... -
New parametric solutions of some abel equations
( University of Miskolc , 2016 , Article)New parametric solutions of some Abel equations of second kind are found. The scheme for construction of these solutions utilizes a combination of differential invariants of a symmetry of an associated second order ODE and ... -
A new perspective on the linkages between tourism demand and business cycles
( Wiley-Blackwell , 2022 , Article)Business cycles, that is, the irregular fluctuations in economic activity,affect tourism demand—this is a stylized fact in tourism research. And itis well-founded. After all, as incomes rise, so does the consumption ofgoods ... -
New plain-text authentication secure scheme for implantable medical devices with remote control
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)Implantable medical devices are being increasingly used to treat or monitor different medical conditions. For such purposes, wireless is the most desired communication scheme to be implemented in these devices. On the other ... -
A new PLL method for resolvers
( IEEE , 2010 , Conference Paper)This paper describes a novel implementation of the classical PLL closed loop method without using VCO, DAC, counter and look-up tables. The proposed method makes use of the excitation signal of the resolver to estimate the ... -
New Potassium/Argon Ages For The Volcanic Rocks Of Halul Island (Qatar)
( Qatar University , 1988 , Article)The only rocks of igneous origin known to be exposed in Qatar are those of Halul and Shra'Auh Islands. They occur within a salt diapir and the age of these rocks is uncertain. They have generally been assigned to the Hormuz ... -
New Processing Technique To Improve Physical And Mechanical Properties Of Graphene Nanocomposites
( Hamad bin Khalifa University Press (HBKU Press) , 2014 , Conference Paper)Nanocomposites are commonly used in many applications and new processing techniques are required to improve mechanical and physical properties of these materials. Graphene nanoplatelets (GNPs) have high aspect ratio and ... -
New product development and sustainable performance of Chinese SMMEs: The role of dynamic capability and intra-national environmental forces
( Elsevier , 2020 , Article)Despite a growing research interest in innovation strategies i.e. new product development, very few studies explore how the regional environmental mechanism is inherent in the link between new product development and ... -
