A relativistic positioning system exploiting pulsating sources for navigation across the Solar System and beyond [PDF]
, 2011 We introduce an operational approach to the use of pulsating sources, located at spatial infinity, for defining a relativistic positioning and navigation system, based on the use of null four-vectors in a flatMinkowskian spacetime.

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization
Advanced Materials Interfaces, EarlyView.Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

A Note on Realistic Dividends in Actuarial Surplus Models
Risks, 2016 Because of the profitable nature of risk businesses in the long term, de Finetti suggested that surplus models should allow for cash leakages, as otherwise the surplus would unrealistically grow (on average) to infinity.

Investigation of practical applications of H infinity control theory to the design of control systems for large space structures [PDF]
The applicability of H infinity control theory to the problems of large space structures (LSS) control was investigated. A complete evaluation to any technique as a candidate for large space structure control involves analytical evaluation, algorithmic ...

Advanced Materials Technologies, EarlyView.This review outlines how understanding bone's biology, hierarchical architecture, and mechanical anisotropy informs the design of lattice structures that replicate bone morphology and mechanical behavior. Additive manufacturing enables the fabrication of orthopedic implants that incorporate such structures using a range of engineering materials ...

Ductility Tuning via Cluster Network Characteristics of Porous Components
Advanced Materials Technologies, EarlyView.Network optimization via cluster characteristics induced by interaction of stress concentration is proposed, demonstrating increased cluster size and dispersion in non‐uniform porous components. The optimized structures exhibit, for the first time, that enhanced ductility and damage progression is controllable through zigzag cluster network designed by

Fourier Transform of Transfer Matrices of Plane Ising Models
Современные информационные технологии и IT-образование, 2019 This work demonstrates the Fourier transform of the elementary transfer matrix of the generalized two-dimensional Ising model with special boundary conditions with a shift (screw type) with the form of a Hamiltonian covering the classical Ising model ...

Actual Infinity: A Pseudo-problem or a Meta-Foundation of Western European Philosophy and Science?
Ideas and Ideals, 2021 The author of the article reveals the theological context of the origin of the concept of actual infinity and clarifies the problem of actual infinity. The author shows that this problem is not a paradoxical category of thinking, but a problem of the unity of two realities (eternal, unchanging and infinite, and temporary, changeable and finite), which ...

The Aleph Zero or Zero Dichotomy [PDF]
, 2006 The Aleph Zero or Zero Dichotomy is a strong version of Zeno's Dichotomy II which being entirely derived from the topological successiveness of the w-order comes to the same Zeno's ...

The Canonical Form of the Rabi Hamiltonian
, 1996 The Rabi Hamiltonian, describing the coupling of a two-level system to a single quantized boson mode, is studied in the Bargmann-Fock representation. The corresponding system of differential equations is transformed into a canonical form in which all ...
