Two‐beam photoacoustic phase measurement of the thermal diffusivity of solids
- O. Pessoa, C. Cesar, N. Patel, H. Vargas, C. C. Ghizoni, L. Miranda
- Physics
- 15 February 1986
A simple method is demonstrated for obtaining the thermal diffusivity of solids, by measuring the phase lag between a front and rear illumination, at a single chopping frequency. The method is tested… Expand

Bell’s theorem without inequalities: on the inception and scope of the GHZ theorem
Since its inception, fifty years ago, Bell’s theorem has had a long history not only of experimental tests but also of theoretical developments. Studying pairs of correlated quantum-mechanical… Expand
Modeling the Causal Structure of the History of Science
- O. Pessoa
- Mathematics
- 2010
This paper is an overview of an approach in the philosophy of science of constructing causal models of the history of science. Units of scientific knowledge, called “advances”, are taken to be… Expand
Low‐density polyethylene depth profile analysis by photoacoustic spectroscopy
- M. G. Oliveira, O. Pessoa, H. Vargas, F. Galembeck
- Chemistry
- 20 May 1988
Near-infrared photoacoustic spectra of polyethylene (1 mm slab) were taken in the modulation range 10–240 Hz, which corresponds to thermal diffusion layers in the 56−11 μm range. Thick-layer spectra… Expand
Simplerealizations of generalized measurements in quantum mechanics
- O. Pessoa
- Physics
- 1 October 1994
This paper discusses the approach to the analysis of measurements in quantum mechanics which is based on a set of "detection operators" forming a resolution of identity. The expectation value of each… Expand
Reversibility and the Interpretation of Mixtures in Quantum Mechanics
- O. Pessoa
- Mathematics
- PSA: Proceedings of the Biennial Meeting of the…
- 1 January 1992
This paper examines the problem of the interpretation of mixtures in quantum mechanics, presenting a survey of the philosophical debate between the ignorance interpretation (IgI) and the… Expand
Causal Models in the History of Science
- O. Pessoa
- Sociology
- 1 July 2005
The investigation of a method for postulating counterfactual histories of science has led to the development of a theory of science based on general units of knowledge, which are called "advances".… Expand
