Observation of Pancharatnam-Berry phase for unpolarized and partially polarized light fields

Results in Optics, 2021
Geometric phase, owing to its topological nature and properties of fault tolerance, plays an important role in devising real world applications in both classical and quantum domain.

A Geometric Routing Protocol in Disruption Tolerant Network [PDF]

2009 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.

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

The 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

Influence of NC Program Quality and Geometric Errors of Rotary Axes on S-Shaped Machining Test Accuracy

Journal of Manufacturing and Materials Processing, 2018
An S-shaped machining test is proposed for the ISO 10791-7 standard to verify the performance of five-axis machining centers. However, investigation of the factor that has the most influence on the geometrical accuracy of finished S-shaped workpieces has

A study on tolerance design of machine tool components based on shape generation motions (Theoretical analysis considering rotational table positions)

Nihon Kikai Gakkai ronbunshu, 2017
The kinematic motion deviations of the five-axis machining centers are deeply influenced by the geometric deviations of the components, such as guide-ways and bearings.

Redrawing a graph within a geometric tolerance [PDF]

, 1995
In this paper we investigate some applications of the concept of tolerance to graph drawing. Given a geometric structure, the tolerance is a measure of how much the set of points can be arbitrarily changed while preserving the structure. Then, if we have a layout of a graph and we want to redraw the graph while preserving the mental map (captured by ...

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.
