Synchronization between reference frames in Lorentz transformation Yuri Heymann 3 rue Chandieu, 1202 Geneva, Switzerland (Dated: November 27, 2011) Abstract A solution to the problem of distant clock synchronization moving with respect to each other is being proposed by introducing an initial distance between reference frames in the Lorentz transformation. The problem requires to add a dummy dimension to the reference frames in order to preserve the Lorentz transformation. Based on a invariance between reference frames, a physical interpretation of this new dimension is proposed.

Change of framework between light travel distances and Euclidean distances Yuri Heymann 3 rue Chandieu, 1202 Geneva, Switzerland (Dated: October 18, 2011) Abstract A new theory based on the propagation of light in an expanding space is presented in the herein study. From the change of framework between Light Travel Distances and Euclidean distances, a formula is derived to compute distances function of redshifts. This formula that was obtained from a theory of the propagation of light in an expanding space is the same than Mattig formula (with q = 1/2) that is based on a theory of gravity (the general relativity). I. INTRODUCTION Euclidean distances were introduced in [1], and it was suggested that Euclidean distances need to be used in order to derive the galactic density profiles . The LTD (Light Travel Distance) is the distance traversed by a photon between the time it is emitted and the time it reaches the observer. In astronomical units, the Eu

Prepared for submission to JCAP Redshift adjustment to the distance modulus Yuri Heymann 3 rue Chandieu, 1202 Geneva, Switzerland E-mail: y. heymann@yahoo. com Abstract. The principal objective of this study is to provide a model for the redshift adjustment to distance modulus. The distance modulus is derived from the logarithm of the ratio of observed fluxes of astronomical objects. The observed fluxes need to be corrected for the redshift as the energy flux measured with respect to the emitted energy flux is proportional to the wavelength ratio of the emitted to observed light. By introducing this redshift adjustment to the distance modulus, we find out that the apparent ”acceleration” of the expansion of the Universe that was obtained from observations of supernovae cancells out. Keywords: Acceleration expansion, distance modulus, redshift

The principal objective of this study is to provide a method to build galactic density profiles. The model developed in this study was calibrated using the zCosmos galactic survey. Two antagonistic scenarios were evaluated, respectively: (1) assuming that light travel distances are additive, and (2) using a model for the motion of the photon in an expanding space assuming that the speed of light is frame-independent. The herein study suggests that light travel distances need to be converted into Euclidean distances in order to derive the galactic density profile of the survey, which is the evolution of galactic density over time. In addition, the present study indicates an Omega matter of 0.19.

The principal objective of this study was to investigate viability kinetics in aerobic AS (Activated Sludge). A kinetic model was developed in order to predict viable cells, non-degraded dead cells and inert VSS (Volatile Suspended Solids) in a reactor – usually conventional models only predict active biomass and inert VSS. The following processes were considered in the derivation of the model: the death rate of viable cells, and the hydrolysis rate of dead cells. Equations development led to a decay coefficient (b) – previously considered constant – function of death rate, hydrolysis rate and solid retention time. Cell growth on soluble COD (Chemical Oxygen Demand) resulting from lysis/hydrolysis has been introduced in the model. Simulation methods of viability in AS, and OUR (Oxygen Uptake Rate) tests of AS in batch under starvation were developed in order to validate the model, and to determine its parameters. The results of this study indicate that the proposed model is c
