Experimental Study of the Interfacial Waves in Horizontal Stratified Gas-liquid Two-phase Flows by Using the Developed Image Processing Technique
Hadiyan Yusuf Kuntoro, Akhmad Zidni Hudaya, Okto Dinaryanto +2
Experimental series of stratified gas-liquid two-phase flows had been carried out in a 26 mm i.d. transparent acrylic horizontal pipe. The study was aimed to determine the interfac…
A Study of Three Dimensional Bubble Velocities at Co-current Gas-liquid Vertical Upward Bubbly Flows
Hadiyan Yusuf Kuntoro, Manuel Banowski, Deendarlianto
Recently, experimental series of co-current gas-liquid upward bubbly flows in a 6 m-height and 54.8 mm i.d. vertical titanium pipe had been conducted at the TOPFLOW thermal hydraul…
Inflation due to a non-minimal coupling of singlet scalars in the radiative seesaw model
Romy H. S. Budhi, Shoichi Kashiwase, Daijiro Suematsu
The radiative neutrino mass model with inert doublet dark matter is a promising model for the present experimental issues which cannot be explained within the standard model. We st…
Level product form QSF processes and an analysis of queues with Coxian inter-arrival distribution
Dwi Ertiningsih, Michael N. Katehakis, Laurens C. Smit +1
In this paper we study a class of Quasi-Skipfree (QSF) processes where the transition rate submatrices in the skipfree direction have a column times row structure. Under homogeneit…
Persistent spin helix on a wurtzite ZnO(10-10) surface: First-principles density-functional study
Moh Adhib Ulil Absor, Fumiyuki Ishii, Hiroki Kotaka +1
The persistent spin helix (PSH) that has been widely and exclusively studied in zinc-blende structures is revealed for the first time on the surface of a wurtzite structure. Throug…
Constrained inflaton due to a complex scalar
Romy H. S. Budhi, Shoichi Kashiwase, Daijiro Suematsu
We reexamine inflation due to a constrained inflaton in the model of a complex scalar. Inflaton evolves along a spiral-like valley of special scalar potential in the scalar field s…
