System’s reusability and cost are very important in software product line design area. Developers’ goal is to increase system reusability and decreasing cost and efforts for building components from scratch for each software configuration. This can be reached by developing software product line (SPL). To handle SPL engineering process, several approaches with several techniques were developed. ...

Fine/ultrafine particles can easily reach the pulmonary acinus, where gas is exchanged, but they need to mix with alveolar residual air to land on the septal surface. Classical fluid mechanics theory excludes flow-induced mixing mechanisms because of the low Reynolds number nature of the acinar flow. For more than a decade, we have been challenging this classical view, proposing the idea that c...

We study various mixing properties for subshifts, which allow words in the language to be concatenated into a new word in the language given certain gaps between them. All are defined in terms of an auxiliary gap function f : N → N, which gives the minimum required gap length as a function of the lengths of the words on either side. In this work we focus mostly on topological transitivity, topo...

In this study, the mixing phenomena and fluid dynamics in a copper converter have been experimentally investigated using a physical model. The physical model is a 1:5 horizontal tank made of Plexiglas. The mixing phenomena have been characterized by experimentally measuring the mixing time using a tracer dispersion technique. Moreover, the effects of the air flow rate and lance submergence on t...

A numerical study of 3D electrokinetic flows through micromixers was performed. The micromixers considered here consisted of heterogeneous rectangular microchannels with prescribed patterns of zeta-potential at their walls. Numerical simulation of electroosmotic flows within heterogeneous channels requires solution of the Navier-Stokes, Ernest-Plank and species concentration equations. It is kn...

Code-mixing and code-switching can effectively deal with the complex communicative demands that arise when participants have varied levels of linguistic ability. This paper aimed to examine functions code-mixing code switching uttered by Cinta Laura Kiehl in Bang Denny Sumargo Interview Show on August 18th 2021 entitled “Terjebak Toxic Relationship'' (In A Relationship). The design this study u...

Like other developing countries, especially Malaysian urban youths, are continuously creating their “own language” to set themselves apart from the older generation. Referred as Generation Z or Gen (post-millennials), these group of youths use slang that takes form code-mixing, abbreviations and ‘nonstandard variety’ languages. First, this study aimed reveal patterns youth language incorporated...

We present in this paper a uni ed processing for Real, Integer and Boolean Constraints based on a general narrowing algorithm which applies to any n-ary relation on <. The basic idea is to de ne, for every such relation , a narrowing function ! based on the approximation of by a Cartesian product of intervals whose bounds are oating point numbers. We then focus on non-convex relations and estab...
