Analyzing warp drive spacetimes with Warp Factory [PDF]

open access: yesClassical and Quantum Gravity
Abstract The field of warp research has been dominated by analytical methods to investigate potential solutions. However, these approaches often favor simple metric forms that facilitate analysis but ultimately limit the range of exploration of novel solutions.

Curvature Invariants for the Alcubierre and Natário Warp Drives

open access: yesUniverse, 2021
A process for using curvature invariants is applied to evaluate the metrics for the Alcubierre and the Natário warp drives at a constant velocity. Curvature invariants are independent of coordinate bases, so plotting these invariants will be free of ...

Enhancing the Ballistic Performances of 3D Warp Interlock Fabric Through Internal Structure as New Material for Seamless Female Soft Body Armor Development

open access: yesApplied Sciences (Switzerland), 2020
This paper investigates the effects of warp yarns ratios on the ballistic performances of three-dimensional (3D) warp interlock p-aramid fabrics. Four 3D warp interlock variants with different binding and stuffer warp yarns ratios were designed and ...

Development of an individual warp beam tension control system for warp assembling machines in direct warp preparation [PDF]

open access: yesJournal of Engineered Fibers and Fabrics
Warp preparation is a process prior to weaving that brings all the ends side by side and then winding them on a warp beam with the same tension and length at a predetermined width, density and length.

Black holes, warp drives, and energy conditions

open access: yesPhysics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics
Following the work of H. Ellis, we study warp drives in the gravitational field of a Schwarzschild black hole. We find that as long as the warp drive crosses the black hole horizon at a subluminal speed, the horizon would be effectively absent inside the

Warped flatland [PDF]

open access: yesJournal of High Energy Physics, 2020
Abstract We study warped flat geometries in three-dimensional topologically massive gravity. They are quotients of global warped flat spacetime, whose isometries are given by the 2-dimensional centrally extended Poincaré algebra. The latter can be obtained as a certain scaling limit of Warped AdS3 space with a positive cosmological

AÇIĞA ÇIKARILAN TERCİHLER: TEORİ VE UYGULAMA

open access: yesMehmet Akif Ersoy Üniversitesi İktisadi ve İdari Bilimler Fakültesi Dergisi, 2021
Türkiye’deki hanehalkları için açığa çıkarılan tercih teorisinin geçerliliğinin test edilmesinin, tüketici tercihlerindeki rasyonelliğin belirlenmesinin ve rasyonalitenin ihlal edilmesi durumunda ortaya çıkan refah kayıplarının ölçülmesinin amaçlandığı ...
