Morphological Distribution of Galaxies in Some Nearby Clusters

open access: yesOpen Astronomy, 2019
We study the morphological distribution of galaxies in some nearby clusters, using the Sloan Digital Sky Survey – Data Release 9 (SDSS-DR9). The segregation between early-type galaxies and late-type ones is investigated in g – r / u – g color space ...

A fuzzy pert approach to evaluate plant construction project scheduling risk under uncertain resources capacity

open access: yesJournal of Industrial Engineering and Management, 2009
A plant construction project always involves lots of activities. Precise information about the activities duration is unfortunately unavailable due to the uncertain resources capacity.

Protection System Design of Induction Motor for Industries

open access: yesModelling and Simulation in Engineering, 2022
The fundamental and durable structures of induction motor, as well as their low manufacturing cost, make them popular components in a wide range of current applications. Providing a safety net for employees is a must-have for businesses.

NRASQ61R Expression in Lymphatic Endothelial Cells Causes Enlarged Vessels, Hemorrhagic Chylous Effusions, and High Mortality in a Mouse Model of Kaposiform Lymphangiomatosis

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Kaposiform lymphangiomatosis (KLA) is an aggressive complex lymphatic anomaly. Patients exhibit malformed lymphatic vessels and often develop hemorrhagic effusions and elevated angiopoietin‐2 (Ang‐2) levels. A somatic NRAS p.Q61R (NRASQ61R) mutation has been associated with KLA.

Weighted Dirac combs with pure point diffraction

open access: yes, 2004
A class of translation bounded complex measures, which have the form of weighted Dirac combs, on locally compact Abelian groups is investigated. Given such a Dirac comb, we are interested in its diffraction spectrum which emerges as the Fourier transform

Computation and visualization of photonic quasicrystal spectra via Blochs theorem

open access: yes, 2008
Previous methods for determining photonic quasicrystal (PQC) spectra have relied on the use of large supercells to compute the eigenfrequencies and/or local density of states (LDOS).

Analytic properties of approximate lattices [PDF]

open access: yes, 2019
We introduce a notion of cocycle-induction for strong uniform approximate lattices in locally compact second countable groups and use it to relate (relative) Kazhdan- and Haagerup-type of approximate lattices to the corresponding properties of the ...

Influence of Metro Shield Left/Right Line Tunnel Parallel Under-passing on the Defor-mation and Stress of Existing Open-cut Highway Tunnel under Deformation Joint Working Condition

open access: yesChengshi guidao jiaotong yanjiu
Objective To ensure the successful implementation of metro shield tunnel parallel under-passing through the existing open-cut highway tunnel project under deformation joint condition, it is necessary to analyze the deformation situation and stress ...

Material management comparison between lot for lot and field actual condition [PDF]

open access: yesE3S Web of Conferences
Project material management aims to regulate effective and efficient use materials because material is a resource the largest percentage of the total project cost.

Jordan algebras over icosahedral cut-and-project quasicrystals

open access: yesJournal of Geometry and Physics
In this paper we present a general setting for aperiodic Jordan algebras arising from icosahedral quasicrystals that are obtainable as model sets of a cut-and-project scheme with a convex acceptance window. In these hypothesis, we show the existence of an aperiodic Jordan algebra structure whose generators are in one-to-one correspondence with elements
