In this work we study the effect of the glass substrate on the efficiencies of the different orders that propagate inside a transmission sinusoidal diffraction grating. Holographic optical elements are usually recorded on a photosensitive medium deposited on to a…

A review of all known descriptions of immature stages of the species of the genera Scaeva Fabricius, 1805, Ischiodon Sack, 1913 and Simosyrphus Bigot, 1882 is presented using SEM illustrations. The third instar larval and/or pupal morphology of Scaeva dignota…

The MIT Libraries'€™ proposed to the Mellon Foundation to plan a preservation archive for
dynamic electronic journals (DEJA : a€“ Dynamic E-Journal Archive) that would be reliable, secure,
enduring, and sustainable over the long term. The Foundation'€™s own request for…

The classical problem of the deflection of a cantilever beam of linear elastic material, under the action of an external vertical concentrated load at the free end, is analysed. We present the differential equation governing the behaviour of this physical…

The subject matter of this work is focused in the development of an application for team work over a distributed system belonging to an organization.
This choice is based in the organizations need of their members’ continuing formation/training, and of…

There is a need of counting on precise measurements of subjective losses that can be used for predicting the quality of an image. The objective of the present work is to determine these distortion measurements and test the use of…

The main goal of this thesis was to design new parallel processing strategies specially conceived for distributed environments in order to solve numerical and structural problems from the field of process systems engineering more efficiently. More specifically, the numerical sample…

The MIT Libraries has built a durable digital document repository called DSpace to house the
digital output of our faculty's research. DSpace will be a home for the digital documents our
faculty want to share with their colleagues around the…

Se presenta una guía para resolver y estudiar modelos de expectativas racionales dinámicas lineales (LDRE). Luego de codificar el modelo, se aplica una function simple para log-linealizarlo; simular los efectos de series exógenas de shocks; calcular condiciones de momentos muestrales…
