Quantum-like approach to financial risk: quantum anthropic principle
We continue the analysis of quantum-like description of market phenomena and
economics. We show that it is possible to define a risk inclination operator
acting in some Hilbert space that has a lot of common with quantum description
of the harmonic oscillator. The approach has roots in the recently developed
quantum game theory and quantum computing. A quantum anthropic principle is
formulatedComment: 6 pages, LaTeX, to be published in Acta Physica Polonica
The thermodynamics of portfolios
We propose a new method of valuation of portfolios and their respective
investing strategies. To this end we define a canonical ensemble of portfolios
that allows to use the formalism thermodynamics.Comment: 8 pages, LaTeX, appolb.cls is require
Lunar orbital photogaphic planning charts for candidate Apollo J-missions
A technique is presented for minimizing Mapping Camera film usage by reducing redundant coverage while meeting the desired sidelap of greater than or equal to 55%. The technique uses the normal groundtrack separation determined as a function of the number of revolutions between the respective tracks, of the initial and final nodal azimuths (or orbital inclination), and of the lunar latitude. The technique is also applicable for planning Panoramic Camera photography such that photographic contiguity is attained but redundant coverage is minimized. Graphs are included for planning mapping camera (MC) and panoramic camera (PC) photographic passes for a specific mission (i.e., specific groundtracks) to Descartes (Apollo 16), for specific missions to potential Apollo 17 sites such as Alphonsus, Proclus, Gassendi, Davy, and Tycho, and for a potential Apollo orbit-only mission with a nodal azimuth of 85 deg. Graphs are also included for determining the maximum number of revolutions which can elapse between successive MC and PC passes, for greater than or equal 55% sidelap and rectified contiguity respectively, for nodal azimuths between 5 deg and 85 deg
