Phase-decoupled method for three-phase power-flow analysis of unbalanced distribution systems

, 2015
This paper presents a three-phase power-flow solution method for unbalanced distribution networks, in which each phase is modelled in a decoupled way and therefore can be solved independently.

Phase singularities in isotropic random waves [PDF]

, 2000
The singularities of complex scalar waves are their zeros; these are dislocation lines in space, or points in the plane. For waves in space, and waves in the plane (propagating in two dimensions, or sections of waves propagating in three), we calculate ...

The least variable phase type distribution is erlang

Communications in Statistics. Stochastic Models, 1987
Let \((X_ t,t\geq 0)\) be a continuous-time Markov process with state space \(\{\) 0,1,...,n\(\}\) where 0 is an absorbing state, and let \(T_{n0}\) denote the time to reach 0 if \(X_ 0=n\). It is shown that \(var(T_{n0})/(E T_{n0})\) \(2\geq 1/n\) with equality if and only if \((X_ t,t\geq 0)\) is a pure death process with constant death rate.

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Análisis de trayectorias estudiantiles mediante distribuciones de fase discretas acíclicas

Revista Latinoamericana de Estudios Educativos
En este trabajo se analizan las trayectorias estudiantiles mediante mezclas de distribuciones de fase discretas acíclicas. El modelo propuesto combina una distribución de Coxian discreta para estimar las probabilidades de deserción en los semestres ...

Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma

Molecular Oncology, EarlyView.
The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...

Measurement and Visualization of R410A Distribution in the Vertical Header of the Microchannel Heat Exchanger

, 2012
This paper presents the refrigerant adiabatic upward flow in the vertical header of microchannel heat exchanger and its effect on distribution. R410A is circulated into the header through the microchannel tubes (5 or 10 tubes) in the bottom pass and ...
