Abstract Numerical simulations were carried out to study the influence of ozone on Ignition Delay Time (IDT) iso-octane/air mixtures under typical operating conditions HCCI engines. 0-D and 2-D CFD compute IDT characterize compression, combustion, expansion in an engine, respectively. A kinetic model was developed by merging a mechanism for iso-octane, sub-mechanism nitrogen oxides, ozone. The ...

this study was conducted in order to evaluate the effects of long term ageing on toughness andresilient modulus of asphalt concrete mixtures containing electric arc and basic oxygen furnacesteel slags. after initial evaluation of the properties of steel slags using x-ray diffraction andscanning electric microscope, eleven sets of laboratory mixtures were prepared. each set wastreated replacing ...

Surface acoustic wave (SAW) excitation of an acoustic field in a trapezoidal glass microfluidic channel for particle manipulation in continuous flow has been demonstrated. A unidirectional interdigital transducer (IDT) on a Y-cut Z-propagation lithium niobate (LiNbO3) substrate was used to excite a surface acoustic wave at approximately 35 MHz. An SU8 layer was used for adhesive bonding of the ...

We demonstrate that the propagation path of a surface acoustic wave (SAW), excited with an interdigitated transducer (IDT), can be visualized using a thin liquid film dispensed onto a lithium niobate (LiNbO3) substrate. The practical advantages of this visualization method are its rapid and simple implementation, with many potential applications including in characterising acoustic pumping with...

The adoption and use of information technology (IT) innovations within an organization are critical to deriving the benefits of IT, yet many innovations are underused or never used. Theoretical perspectives that have been used to analyze individual behavior regarding IT usage include innovation diffusion theory (IDT) and the theory of planned behavior (TPB). IDT states that adoption of an innov...

Software measures are recommended for the effective management of software development projects. Innovation diffusion theory (IDT) provides perspective for understanding managers’ and software developers’ perceptions of the relative advantage, complexity, and compatibility of software measures. This paper describes the results of a survey in which software developers and managers identified a s...

Intuitionistic epistemic logic is an active research field. However, so far no consensus has been reached what the correct form of intuitionistic epistemic logic is and more technical and conceptual work is needed to obtain a better understanding. This article tries to make a small technical contribution to this enterprise. Roughly speaking, a proposition is distributed knowledge among a group ...

The Global Partnership for Effective Diabetes Management has previously recommended the implementation of an interdisciplinary team (IDT) approach to type 2 diabetes (T2DM) management as one of 10 practical steps for health care professionals to help more people achieve their glycaemic goal. This article discusses some of the key contributors to success and also the challenges faced when applyi...

Cloud computing is a new technology that has been applied to education and has e nabled the development of cloud computing classrooms; however, student behavioral intentions toward cloud computing remain unclear. Most researchers have evaluated, integrated, or compared few (1 to 3) theories to examine user behavioral intentions and few have addressed additional theories or models. In this study...
