Resonance Control Cooling System for a Proto-Type Coupled Cavity Linac
Chrisine A. Treml,Stanley K. Brown,John D. Bernardin
Physics , 2001,
Abstract: Los Alamos National Laboratory (LANL) is designing a coupled cavity linac (CCL) for the Spallation Neutron Source (SNS) being built at Oak Ridge National Laboratory (ORNL). As part of the design process, a proto-type, Hot Model, consisting of two segments of the SNS CCL was manufactured and installed at LANL. An RF source was applied to the Hot Model to determine the success of the cavity design, the effectiveness of the control algorithms and cooling systems, and the validity of the Resonance Control Cooling System (RCCS) model used during the Hot Model design. From a system controls perspective, an overview of the hot model, a description of the RCCS, and the pertinent data from the RF tests will be presented.
The Mind-Body Problem Today  [PDF]
Gabriel Vacariu
Open Journal of Philosophy (OJPP) , 2011, DOI: 10.4236/ojpp.2011.11005
Abstract: An old philosophical problem, the mind-body problem, has not been yet solved by philosophers or scientists. Even if in cognitive neuroscience has been a stunning development in the last 20 years, the mind-body problem remained unsolved. Even if the majority of researchers in this domain accept the identity theory from an ontological viewpoint, many of them reject this position from an epistemological viewpoint. In this context, I consider that it is quite possible the framework of this problem to be wrong and this is the main reason the problem could not be solved. I offer an alternative, the epistemologically different worlds perspective, that replace the world or the universe. In this new context, the mind-body problem becomes a pseudo-problem.
Analysis of Dynamics Fields in Noninertial Systems  [PDF]
Gabriel Barceló
World Journal of Mechanics (WJM) , 2012, DOI: 10.4236/wjm.2012.23021
Abstract: In this paper, I present evidence that there exists an unstructured area in the present general assumptions of classical mechanics, especially in case of rigid bodies exposed to simultaneous noncoaxial rotations. To address this, I propose dynamics hypotheses that lead to interesting results and numerous noteworthy scientific and technological applications. I constructed a new mathematical model in rotational field dynamics, and through this model, results based on a rational interpretation of the superposition of motions caused by torques were obtained. For this purpose, I analyze velocity and acceleration fields that are generated in an object with intrinsic angular momentum, and assessed new criteria for coupling velocities. In this context, I will discuss reactions and inertial fields that cannot be explained by classical mechanics. The experiments have been analyzed and explained in a video accompanying this text. I am not aware of any concurrent study on the subject and conclusions evidenced in this paper, preventing us from making additional theoretical com- parisons or indicate to the reader other sources to compare criteria.
Proposal of New Criteria for Celestial Mechanics  [PDF]
Gabriel Barceló
International Journal of Astronomy and Astrophysics (IJAA) , 2013, DOI: 10.4236/ijaa.2013.34044
Abstract:

Based on a new interpretation on the behavior of rigid bodies exposed to simultaneous non-coaxial rotations, we have developed a hypothesis: the Theory of Dynamics Interactions, which can be applied to understand celestial mechanics. We have analyzed the velocity and acceleration fields generated in a rigid body with intrinsic angular momentum, when exposed to successive torques, to assess new criteria for this speeds coupling. In this context, reactions and inertial fields take place, which cannot be justified by means of classical mechanics. We believe that the results obtained after the analysis of dynamics fields systems accelerated by rotation will allow us to conceive a new perspective in celestial dynamics, astrometry, stellar dynamics and galactic astronomy, unknown up to date. After carrying out ample research, we have come to the conclusion that there still exists an unstructured scientific area under the present general assumptions and, more specifically, in the area of dynamic systems submitted to rotational accelerations. The aim of this paper is to present information of the surprising results obtained, and to attract the interest towards the investigation of this new area of knowledge in rotational non-inertial dynamics, and its multiple and remarkable scientific applications.

YintelligenceTM: The Mapping of the Pre-Heaven or FuXi Hexagrams to the Post-Heaven or King Wen Hexagrams  [PDF]
Gabriel Felley
Chinese Studies (ChnStd) , 2013, DOI: 10.4236/chnstd.2013.24032
Abstract: The Yijing易經belongs to the famous group of the five classics. In the Ming and Qing dynasties, the Four Books and Five Classics四書五經 were the subject of mandatory study by those Confucian scholars who wished to become government officials. The Yijing (Faure & Javary, 2002) consists of 64 figures called hexagrams 卦 formed by six Yin (broken) or Yang (unbroken) lines and commentaries on each of these hexagrams and their lines. The whole set of the hexagrams and their interdependencies make a dynamic model for the understanding or the anticipating of the different steps change goes through. The Yijing does not predict the future but gives a snap-shot of the actual situation and the holistic potentialities which may be deployed or not in order to better adapt to the on-going change. The different stages of a change are explained by the Yin-Yang polarity and the never-ending transformation of old-Yin 老陰in young-Yang少陽, old-Yang老陽, young-Yin少陰 and old-Yin again. The 64 hexagrams are built by pairing the 8 basic trigrams obtained by adding to each bigram a supplementary Yin or Yang line. Figure 1 depicts a 4-regions space (East/young Yang, South /old Yang, West/young Yin, North/old Yin) and a cyclic movement. A forthcoming article will explain the relation between this space organization and the whole set of 64 hexagrams as a network. The cyclic change is of major interest. Purpose: The 64 hexagrams of the Yijing are organized in 16 “first degree” nuclear families (Javary, 1997), which may be consolidated in 4 “second degree” nuclear families. There are another 16 families organizing the 64 hexagrams in a different structure. In the literature they are called the pre-heaven先天 hexagrams (Schlumberger, 1987), and in this paper they are referred to as the FuXi伏羲 hexagrams. They form 16 cyclic families, whose structure will be analyzed in this paper. This cyclicity induces a “predecessor-successor” relationship between the hexagrams belonging to the same FuXi family: H1H2H3H4H1. While the 4 members of each nuclear family are centered on a “master” hexagram that corresponds to a common inner lines’ structure, each FuXi family is cyclically structured and we call the hexagrams belonging to the
Theory of Dynamic Interactions: The Flight of the Boomerang  [PDF]
Gabriel Barceló
Journal of Applied Mathematics and Physics (JAMP) , 2014, DOI: 10.4236/jamp.2014.27063
Abstract:

We propose a new interpretation of the dynamic behavior of the boomerang and, in general, of the rigid bodies exposed to simultaneous non-coaxial rotations. We have developed a new rotational non-inertial dynamics hypothesis, which can be applied to understand both the flight of the boomerang as well as celestial mechanics. The boomerang is a particularly significant, intriguing and widely known case of bodies in rotation. We have analyzed the velocity and acceleration fields generated when rigid bodies are exposed to successive torques, in order to assess new criteria for this speed coupling. In this context, reactions and inertial fields that cannot be justified by means of classical mechanics take place. Accordingly, we propose a new Theory of Dynamic Interactions. We believe that the results obtained will enable us to conceive a new perspective in dynamics, unknown to date. After carrying out ample research, we have come to the conclusion that there still exists an unstructured scientific area in non-inertial dynamics systems subject to rotational accelerations. The aim of this paper is to present information of the surprising results obtained and to attract interest in research into dynamic field systems accelerated by rotation, and the multiple and remarkable scientific applications arising thereof. We further propose the boomerang as a clear example of the application of the Theory of Dynamic Interactions.

Common Factors in International Bond Returns and a Joint ATSM to Match Them  [PDF]
Christian Gabriel
Theoretical Economics Letters (TEL) , 2014, DOI: 10.4236/tel.2014.47067
Abstract:

The existence of common factors in international bond markets is an important cause for modelling different term structures of interest rates jointly. This paper investigates the common factors of US and UK treasury yields in the period of 1983 to 2012. A principal component analysis motivates the type of joint ATSM for modelling the yield curves of two distinct economies. In sum, two common factors explain 85% of the yield variation and the model factors have a solid economic intuition.

Theory of Dynamic Interactions: Laws of Motion  [PDF]
Gabriel Barceló
World Journal of Mechanics (WJM) , 2013, DOI: 10.4236/wjm.2013.39036
Abstract:

The aim of this paper is to present the laws of motion that can be derived from the Theory of Dynamic Interactions, and of its multiple and significant scientific applications. Based on a new interpretation on the behaviour of rigid bodies exposed to simultaneous non-coaxial rotations, we have developed a hypothesis regarding the dynamic behaviour of these bodies. From these hypotheses and following the observation of the behaviour of free bodies in space, we have developed axioms and a mathematical-physical model. Consequently, we have deduced a movement equation, coherent with the hypotheses and the observed behaviour. This dynamic model, in the case of rigid solid bodies or systems, allows putting forward a series of laws and corollaries in relation to its dynamic performance. These laws have subsequently been confirmed by experimental tests. The whole of this research constitutes a rational and conceptual structure which we have named Theory of Dynamic Interactions (TID). This logical deductive system allows predicting the behaviour of solid bodies subject to multiple accelerations by rotation. In the conclusions, we underline that coherence has been obtained between the principles and axioms, the developed physical-mathematical model, the obtained movement equation, the deduced laws and the realised experimental tests.  

On Motion, Its Relativity and the Equivalence Principle  [PDF]
Gabriel Barceló
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.517180
Abstract:

The Equivalence Principle put forward by Albert Einstein is currently undergoing comprehensive revision to determine its degree of accuracy. Notwithstanding, this principle refers to a very specific circumstance, as free-fall; thus in our opinion it cannot be generalised to any other movement in space. This paper refers to the dynamic hypotheses of moving rigid bodies and a particular, structured theory that would establish how such bodies behave when subject to different actions that oblige them to make successive, non-coaxial spins. With respect to bodies subject to acceleration by rotation, we understand that there are indications to identify the prior dynamic state of the moving object and that examples of a violation of the aforementioned Equivalence Principle can be deduced thereof. Based on the findings of this paper and the theory put forward herein, we suggest that an observer can identify the prior situation of absolute rest or absolute non-rotation of a body, thus leading to the conclusion that movement does not necessarily have to be a relative concept. The foregoing leads us to propose that the Equivalence Principle is fully valid for the situation put forward by Albert Einstein, but cannot be generalised to any dynamic situation.
