The Quantum Oscillatory Modulated Potential - Part II - The Stability of the Hydrogen Atom  [PDF]
Waldemar Wolney Filho
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.38090
Abstract: The purpose of this work is to show the stability of the hydrogen atom with the use the Quantum Oscillatory Modulated Potential and the Heisenberg equations of motion, postulating that the electron in the hydrogen atom is behaving as a quantum harmonic oscillator. With the electron confined between two potential barriers, created by the new potential function, we are considering that at absolute temperature the power absorbed or emitted by the electron per unit of time can be used to determine the zero point energy of the oscillator. Assuming that electron is only exchanging energy with the nucleus of the atom we are making use of the operators of creation and annihilation of a photon to explain how the energy between the proton and the electron can be exchanged to keep the atom a stable system.
The Quantum Oscillatory Modulated Potential Ⅰ- The Hydrogen Atom  [PDF]
Waldemar Wolney Filho
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.37081
Abstract: In this work we are presenting a modified Coulomb potential function to describe the interaction between two micro-scopic electric charges. In particular, concerning the interaction between the proton and the electron in the hydrogen atom. The modified potential function is the product of the classical Coulomb potential and an oscillatory function dependent on a quantized phase factor. The oscillatory function picks up only selected points along the Coulomb potential, creating potential wells and barriers around the nucleus of the atom. The new potential reveals us new features of the hydrogen atom. Searching for a manner to determine the phase factor, we are using the concept of the de Broglie particle wavelike behavior and the quantum analogue of the virial theorem for describing the bound motion of a particle in a central force field. This procedure is a kind of feedback action, where we are making use of well established concepts of the quantum mechanics aiming to determine the phase factor of the new interaction potential.
Optimal Aggregate Production Plans via a Constrained LQG Model  [PDF]
Oscar S. Silva Filho
Engineering (ENG) , 2014, DOI: 10.4236/eng.2014.612075
Abstract: In this paper, a single product, multi-period, aggregate production planning problem is formulated as a linear-quadratic Gaussian (LQG) optimal control model with chance constraints on state and control variables. Such formulation is based on a classical production planning model developed in 1960 by Holt, Modigliani, Muth and Simon, and known, since then, as the HMMS model [1]. The proposed LQG model extends the HMMS model, taking into account both chance-constraints on the decision variables and data generating process, based on ARMA model, to represent the fluctuation of demand. Using the certainty-equivalence principle, the constrained LQG model can be transformed into an equivalent, but deterministic model, which is called here as Mean Value Problem (MVP). This problem preserves the main properties of the original model such as convexity and some statistical moments. Besides, it is easier to be implemented and solved numerically than its stochastic version. In addition, two very simple suboptimal procedures from stochastic control theory are briefly discussed. Finally, an illustrative example is introduced to show how the extended HMMS model can be used to develop plans and to generate production scenarios.
The Quantum Oscillatory Modulated Potential—Electric Field Wave Packets Produced by Electrons  [PDF]
Waldemar Wolney Filho
Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.614216
Abstract: In this work we are formulating a new theory for describing the waving nature of a microscopic electric particle. Based on the predictions of the Quantum Oscillatory Modulated Potential—QOMP, for describing the interaction between two microscopic electric particles, electron-electron, for instance, we are postulating that the waving behavior of these particles may be an attribute of the charges of the particles and not their masses as currently accepted. For a microscopic electric charge, we are presenting new arguments showing that the electric field in the vicinity of a microscopic charge is spatially waving and can be determined as the gradient per unit of charge of this new quantum interaction potential, with use of an appropriated phase factor to account for the behavior of an unbound electron. Differently of what is predicted by the classical Coulomb electric field, when a charged particle is moving under the action of a potential of V volts, the new electric field existing around the charge has the form of a wave packet. For typical values of the potential V, the wavelength of the waving electric field is in very good agreement with those experimentally observed with diffraction of electrons in crystalline solids.

O silêncio na sala: sobre o declínio da comunica o na vivência conjugal
Ciro Filho
Comunica??o, Mídia e Consumo , 2006,
Abstract: A comunica o humana n o ocorre como normalmente se imagina. Seres humanos utilizam-se muito mais de recursos plásticos de express o (o jeito de olhar, a entona o, o corpo) do que das palavras, que, de certa forma, n o dizem muita coisa. Na vida em comum dos casais, por exemplo, criam-se processos patogênicos que inviabilizam a comunica o, pois o principal da disputa n o s o os temas, os assuntos, as opini es, mas algo que está além da comunica o formal e além do discurso, que está no plano da metacomunica o de suas próprias rela es, de seus padr es, em suma, do poder que, mascarado de contenda de pontos de vista, situa-se no cerne da disputa. Palavras-chave: Patologias da comunica o; comunica o n o-verbal; esquizofrenia e comunica o; metacomunica o. Abstract The human communication does not happen in the way everyone figures it out. Human beings utilize frequently more plastic resources of expression (the way one looks, the tone modulation, the body) than words, that do not say much anyway. In ordinary life of couples for instance pathogenic processes are created and make impossible the communication, for the main altercation is not about themes, matters, opinions but about something that is beyond the formal communication and beyond the discourses and is rather at the level of metacommunication of their own relations, their own patters, in short, at the level of the power that disguised as dispute on opinions is placed in the core of the conflict. Keywords: Communication pathologies; non-verbal communication; communication and schizophrenia; metacommunication.
Paraconsistent Annotated Logic in Analysis of Physical Systems: Introducing the Paraquantum Factor of Quantization hψ  [PDF]
Jo?o Inácio Da Silva Filho
Journal of Modern Physics (JMP) , 2011, DOI: 10.4236/jmp.2011.211172
Abstract: We present in this paper an alternative of modeling physical systems through a non-Classical logic namely the Paraconsistent Logic (PL) whose main feature is the revocation of the principle of non-contradiction. The Paraconsistent Annotated Logic with annotation of two values (PAL2v) is a type of PL and has in its theoretical structure the main feature of dealing with contradictions offering flexibility in drawing conclusions. Several works about applications of PAL2v have shown that such logic is able to provide us with an adequate treatment to uncertainties. Based on the foundations of the PAL2v we presented the ParaQuantum logic (PQL) with the goal of performing analysis of signals from information sources which model physical systems. The formalization of the concepts of the logics PQL, that it is represented in a Lattice, requires the considering of Paraquantum logical states ψ which are propagated through variations of the evidence Degrees µ and λ which come out from measurements performed in Observable Variables in the physical world. When we analyze the lattice of the PQL, we obtain equations which quantify values of physical quantities from where we obtain the effects of propagation of the Paraquantum logical states ψ. In this paper, we introduce the Paraquantum Factor of quantization hψ whose value is associated with a special logical state on the lattice which is identified with the Planck constant h. We conclude through these studies that the Paraquantum Logical Model based on the ParaQuantum logics PQL can link the several fields of the physical sciences by means of quantization of values. It is an innovative approach of formulating natural phenomena.
Analysis of the Spectral Line Emissions of the Hydrogen Atom with Paraquantum Logic  [PDF]
Jo?o Inácio Da Silva Filho
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.33033
Abstract: In this work we presented a study of the obtaining of the spectral line emissions of the hydrogen atom using equations that are originated from the foundations of the Paraquantum Logic (PQL). Based on a class of logics called Paraconsistent Logics with annotation of two values (PAL2v), PQL performs a logical treatment on signals obtained by measurements on physical quantities which are considered Observable Variables in the physical world. In the process of application of the PQL the obtained values are transformed in Evidence Degrees and represented on a Lattice of four Vertices where special equations transform these degrees into Paraquantum logical states ψ which propagate. This allows creating Paraquantum logical models of physical systems of the real world. Using the paraquantum equations, we investigated the hydrogen atom spectrum and his main series known. We performed a numerical comparative study that applies the Paraquantum Logical Model to calculate the wavelengths values. The values of wavelengths obtained by the Paraquantum Equations are compared by the results found by the Rydberg formula and are verified that the series of the spectral line emissions of the hydrogen atom can be identified with the representative Lattices of the Paraquantum Logic. Through the application of the Paraquantum equations it was found a numeric value relates the layers of Paraquantum model of the Hydrogen atom. This value represents a constant that relates the Lattices that compose the Paraquantum universe, and it was denominated Paraquantum Structure Constant, whose symbol is αψ. The obtained results of the comparison demonstrate that the Paraquantum Logic comes with good possibilities of being the ideal logic to model our physical reality.
