Selection indices to identify drought-tolerant grain sorghum cultivars. [PDF]

open access: yes, 2017
Twenty-five cultivars of grain sorghum [Sorghum bicolor (L.) Moench] were examined under both drought stress and normal conditions in 4 experiments. In each condition, genotypes were evaluated in a factorial experiment using a randomized complete block ...

Holonomic quantum computation in decoherence-free subspaces [PDF]

open access: yes, 2005
We show how to realize, by means of non-abelian quantum holonomies, a set of universal quantum gates acting on decoherence-free subspaces and subsystems.

Experimental state control by fast non-Abelian holonomic gates with a superconducting qutrit [PDF]

open access: yes, 2018
Quantum state manipulation with gates based on geometric phases acquired during cyclic operations promises inherent fault-tolerance and resilience to local fluctuations in the control parameters.

Propagation of Geometric Tolerance Zones in 3D [PDF]

open access: yes, 2007
This paper considers error propagation in three dimensional geometric constructions using a geometric approach. First, we present definitions and constructions of tolerance zones for various fundamental elements in Euclidean space. Then, we study in detail the propagation of errors during several geometric computations, including the the distance ...

A Geometric Comparison of Aerofoil Shape Parameterisation Methods [PDF]

open access: yes, 2016
A comprehensive review of aerofoil shape parameterisation methods that can be used for aerodynamic shape optimisation is presented. Seven parameterisation methods are considered for a range of design variables: class function/shape function ...

Automated Generation of Geometric Theorems from Images of Diagrams [PDF]

open access: yes, 2014
We propose an approach to generate geometric theorems from electronic images of diagrams automatically. The approach makes use of techniques of Hough transform to recognize geometric objects and their labels and of numeric verification to mine basic ...

Heat tolerance indices as tools for characterizing resilient wheat (Triticum aestivum) RILs population under thermal stress

open access: yesThe Indian Journal of Agricultural Sciences, 2023
The escalating impact of heat stress on agriculture due to climate change has necessitated the development of heat- tolerant crop varieties. To address this, a study was carried out at research farm of CCS Haryana Agricultural University, Hisar, Haryana

A Geometric Routing Protocol in Disruption Tolerant Network [PDF]

open access: yes2009 29th IEEE International Conference on Distributed Computing Systems Workshops, 2009
We describe a novel Geometric Localized Routing (GLR) protocol in Disruption (Delay) Tolerant Network (DTN). Although DTNs do not guarantee the connectivity of the network all the time, geometric location information still could be used to make routing decisions in a store and forward way.
