Relativistic View

A model, driven by the Einstein's theories of relativity, is suggested. This model tends to correlate the relativistic view on time dilation with the current models and conclusions on time perception. The model uses energy ratios instead of geometrical transformations to approach and express time dilation. Brain mechanisms like the arousal mechanism and the attention mechanism are interpreted and combined. Matrices of order two are generated to contain the time dilation between two observers, from the point of view of a third observer. The matrices are used to transform an observer time to another observer time. Correlations with the official time dilation equations are given in the appendix.

Model-Driven Engineering (MDE) is an approach to software development that uses models as primary artifacts, from which code, documentation and tests are derived. One way of assessing quality assurance in a given domain is to define domain metrics. We show that some of these metrics are supported by models. As text documents, models can be considered from a syntactic point of view i.e., thought of as graphs. We can readily apply graph-based metrics to them, such as the number of nodes, the number of edges or the fan-in/fan-out distributions. However, these metrics cannot leverage the semantic structuring enforced by each specific metamodel to give domain specific information. Contrary to graph-based metrics, more specific metrics do exist for given domains (such as LOC for programs), but they lack genericity. Our contribution is to propose one metric, called s, that is generic over metamodels and allows the easy specification of an open-ended wide range of model metrics.

And Control

When developing a software system, there are a number of principles, paradigms, and tools available to choose from. For a specific platform or programming language, a standard way can usually be found to archive the ultimate system; for example, a combination of an incremental development process, object-oriented analysis and design, and a well supported CASE (Computer-Aided Software Engineering) tool. Regardless of the technology to be adopted, the final outcome of the software development is always a working software system. However, when it comes to software reengineering, there is rather less consensus on either approaches or outcomes. Shall we use black-box or white-box reverse engineering for program understanding? Shall we produce data and control flow graphs, or some kind of formal specifications as the output of analysis? Each of these techniques has its pros and cons of tackling various software reengineering problems, and none of them on its own suffices to a whole reengineering project. A proper integration of various techniques capable of solving a specific issue could be an effective way to unravel a complicated software system. This kind of integration has to be done from an architectural point of view. One of the most exciting outcomes of recent efforts on software architecture is the Object Management Group’s (OMG) Model-Driven Architecture (MDA). MDA provides a unified framework for developing middleware-based modern distributed systems, and also a definite goal for software reengineering. This chapter presents a unified software reengineering methodology based on Model-Driven Architecture, which consists of a framework, a process, and related techniques.

Nature Of Time

I.    Special relativity does not address the fact that time must exist on lifeless worlds. It only addresses time that is observed, which requires that observers be present.II.    The time that exists on lifeless worlds can be termed physical time.III.    The failure to recognize the existence of physical time has resulted in a view of time that is contrived, overly simplistic and contains irrational conclusions which are not experimentally supported.IV.    On worlds where conscious life exists, both physical time and observed time exist. The characteristics of physical time and of observed time are very different.V.    Physical time has the following attributes:a.    Each physical event is associated with physical time.b.    The attributes of absolute time, ‘now’ and time dilation are associated with every physical event.c.    All physical events occur during ‘now’. d.    A physical event results in a change to physical reality.e.    The frame of reference associated with a physical event is universal.f.    In order to be observed, a physical event must have an associated observed event.VI.    Observed time has the following attributes.a.    Every observed event is associated with observed time.b.    An observed event can only occur as the result of a physical event.c.    Multiple observations can be associated with a single physical event.d.    The attribute of ‘now’ and a frame of reference are associated with every observed event.VII.    The duration of physical ‘now’ is a Planck time which is also the unit of measure for absolute time and time dilation.VIII.    Time dilation is computed using the Lorentz transformation.IX.    The statement regarding time dilation “When two observers are in relative uniform motion and uninfluenced by any gravitational mass, the point of view of each will be that the other's (moving) clock is ticking at a slower rate than the local clock” is mathematically, experimentally and logically wrong.X.    During physical ‘now’ a particle may move through space or it may move through time; which it does is a probability based on the speed of the particle expressed as a percentage of the speed of light.

Model Driven Approach

Virtual Organizations are a mechanism where agents can demonstrate their social skills since they can work in a cooperative and collaborative way. Nonetheless, the development of organizations using Multi-Agent Systems (MAS) requires extensive experience in different methodologies and platforms. Model-Driven Development (MDD) is a technique for generating application code that is developed from basic models and meta-models using a variety of automatic transformations. This paper presents an approach to develop and deploy organization-oriented Multi-Agent Systems using a model-driven approach. Based on this idea, we introduce a relatively generic agent-based meta-model for a Virtual Organization, which was created by a comprehensive analysis of the organization-oriented methodologies used in MAS. Following the MDD approach, the concepts and relationships obtained were mapped into two different platforms available for MAS development, allowing the validation of our proposal. In this way, the resultant approach can generate Virtual Organization deployments from unified meta-models, facilitating the development process of agent-based software from the user point of view.

Relativistic View

Abstract Relativity has been based on the implicit assumption that it would exclusively describe interactions. Relativistic view effects are included as well, and they act with no force and no energy exchanges. The Ehrenfest paradox is solved. View effects specific to each point of view are the solution. The calculation of the deflection of light by the sun explains in detail why the deflection angle must be almost double the value obtained with Newton’s laws. The compatibility of General Relativity with the new interpretation is discussed. An object has no speed limit due to gravitation but it is limited in speed with electromagnetism. Inertial behavior is examined. The equivalence principle does not introduce gravitation to General Relativity. Relativity impacts the energy formula of electromagnetism using the Lorentz factor which also introduces view effects that are optical illusions with no impact on energy.

The calculation of the deflection of light by the sun explains in detail why the deflection angle must be almost double the value obtained with Newton’s laws. The compatibility of General Relativity with the new interpretation is discussed. View effects cannot impact total energy. An object has no speed limit due to relativity but can be limited due to other causes. Inertial behavior is examined. Inertial masses are redundant, but this does not introduce gravitation to General Relativity.
