A Spatially Consistent MIMO Channel Model With Adjustable K Factor

IEEE Access, 2019
In the area of research on massive multiple-input multiple-output (MIMO), two assumptions on the wireless channel dominate channel modeling. Either, a rich scattering environment is assumed and the channel is modeled as i.i.d. Rayleigh fading, or, a line

Investigation of the Influence of the k-Factor Parameter on the Quality of Printed Parts Using Ingeo Biopolymer 4043D

Engineering Proceedings
This study examines the influence of the dynamic pressure control parameter in the nozzle during melt deposition onto the build platform (k-Factor), also known as Linear Advance or Pressure Advance in different firmware implementations, on the quality of

Comparison of methods for determination of soil erodibility factor K

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2005
The comparison of values of the soil erodibility factor  K (which is used in the universal equation for soil loss calculation), that were determined according to the main soil units and values of the K factor determined on the base of texture analysis ...

Bridging the Loneliness Gap: Depression, Connectivity, and Isolation in Pediatric Oncology Patients and Their Peers

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.

The kaon semileptonic form factor with near physical domain wall quarks

, 2013
We present a new calculation of the K → π semileptonic form factor at zero momentum transfer in domain wall lattice QCD with N f = 2+1 dynamical quark flavours. By using partially twisted boundary conditions we simulate directly at the phenomenologically

New Ratio Estimators in Simple Random Sampling Using (K) Factor [PDF]

المجلة العراقية للعلوم الاحصائية, 2010
In this research we find alternative ratio estimators to the suggested estimators for [Sesodia and Dwivedi] , [Singh and Kakran] and [Upadhyaya and Singh] , in simple random sampling by using (K) factor.

Cubic graphs having only k-cycles in each 2-factor [PDF]

Discussiones Mathematicae Graph Theory
We consider the class of $2$-connected cubic graphs having only $k$-cycles in each $2$-factor, and obtain the following two results: (i) every 2-connected cubic graph having only $8$-cycles in each $2$-factor is isomorphic to a unique Hamiltonian graph ...

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...

TRANSVERSITY AND DRELL−YAN K-FACTORS [PDF]

Spin 2004, 2005
The Drell-Yan $K$-factors for transversely polarised hadrons are examined. Since transverse spin is peculiar in having no DIS reference point, the effects of higher-order corrections on DY asymmetries are examined via a DIS definition for transversity devised using a hypothetical scalar vertex.
