The three parts of the present appeal successively deal with the following parts of the tragedy: (i) the technological and economical aspects; (ii) the social and philosophical implications; (iii) the moral and spiritual messages. A new way of thinking about identification of correct behavior and management that would allow the living community to evolve towards a optimum future is sketched and the whole of the scientific community is invited to contribute out of conflicts of interest to fill the appeal with the wisdom that Science should be able to bestow to humanity, in conjunction with Arts and Philosophy whose contribution is emphasized.

The author thinks that it is absolutely indispensable to do research on the anticipation of further development in this scope of human activity. This issue constitutes an important problem of our civilisation. The author has published many results of the research within this scope. This research has been carried out for 18 years. On its basis the author has introduced the notion of "The System of Instrumental Civilization" (SIC). This system deals with technical objects production and technology development. Moreover, it deals with the production of services, e.g. banking services. It develops more and more rapidly because of the progress of globalisation. It works on the principle of competition among its particular elements. It is very important that the system remains independent of the considerations on global economy. The development of the system is based on technical problems. Engineers are required to develop new technologies, which are to serve new production. The way the development of technology is realised is also essential. Technical objects are designed. The essence of designing is to make use of experience and practical examinations. A new technical object undergoes some trials. Additionally, its performance in practice is also to be tested.

In Sweden and other European countries death caused by flooding is relatively unusual, but the damages in tangible assets and the cost for the society are considerable. In case of flooding many authorities and organizations become involved and there is a problern to take in the whole situation and have a common picture when many incidents happen at the same time. There is also a lack of efficient tools showing critical buildings and constructions such as roads, railroads, water-purifying plant, etc, in combination with actual and forecasted water levels. In this paper we discuss anticipation of critical factors to be included in a model for visualization of situations caused by flooding.

In this paper, we discuss an analytical optimal solution to the mean-variance formulation of the problem of optimization of multiperiod investment strategy for project portfolio. Specifically, analytical optimal multiperiod investment strategy for project portfolio is derived. An efficient algorithm is proposed in order to maximize the expected value of the terminal wealth under constraint that the variance of the terminal wealth is not greater than a preassigned risk level or to minimize the variance of the terminal wealth under constraint that the expected terminal wealth is not smaller than a preassigned level. A numerical example is given.

Problems in tourism are defined softly and solutions require proper methodology. In this paper, methods of system dynamics and system thinking as well as system dynamics models will be discussed. The importance of modelling, which depends on an organisational problem and participants' experiences, will be shown. A causal loop diagram of a tourism system as a part of national strategy will be developed as well as simplified causal loop diagram from the point of view of national tourism market development. A connection between qualitative and quantitative models will be restored.

The presented variance-free characterization technique is illustrated with testing for normality the empirically observed financial return time series. We further suggest one of the possible extensions of the presented method that can be used for statistical learning with applications in real-time and time-critical systems.

In order to answer to the new market demand industry turn to software vendors looking for specific ERP systems(Davenport 1998) and starting specific projects for supporting Business Process Redesign (BPR). As seen in several industrial contexts few projects ended with success while the majority of them running very quickly out of budget and in serious delay. In this sector authors identified a lack of anticipatory models able to drive the ERP implementation process to the right and they propose in this paper a meta modeling approach able to bridge this gap. Proposed methodology integrates Data Analysis, Regression Meta-Modeling and Artificial Neural Networks processing in order to identiy hidden relationships among KPI and guide the BPR decision makers. The paper outline the proposed methodology as well as a practical application to a real life industrial case.

The paper presents a case study of performance anticipatory analysis, in the context of various functional parameter changes, for the container terminal in Constantza. The results offer valuable information to the management team of the container terminal, in the decision-making process aiming to maximize the terminal efficiency and to offer attractive conditions to their actual or potential clients. The analysis process was conducted using a GPSS simulation model. Anticipated effects of individual and combined functional parameter changes yield by the simulation experiments are extensively discussed.

So, as a hydrologic phenomenon, the sediment transport possesses a kind of uncertainty and ambiguity as well. Recently, use of Artificial Neural Networks (ANNs) and fuzzy sets in simulation and modelling of the systems with uncertainty bas produced suitable results. In this research, for modelling and prediction of sediment transport of river flows, the Adaptive Neuro-Fuzzy Inference System (ANFIS) as a method based on the ANNs and fuzzy sets was used. Using several ANNs and ANFIS models for prediction of sediment load transport showed that using the river discharge in the current period and the river discharge and the sediment load in the previous period as the models nodes, yields the best results.

The technique named nested simulation consists in the simulation of elements that simulate their own environment using their own models. It enables a design process based on on-line predictive simulation to be analysed. Different implementations using SIMULA language have been performed. The features of the tool are presented. The interest for reconfigurable manufacturing systems is discussed.

The presence of integer variables extends fundamentally the areas of MINLP applications. There is a linear goal function subject to linear and nonlinear constraints (quadratic forms). Two dimensional case of integer variables as well as continuous ones is analyzed. Main subject of interest is construction of feasible set of variables. Some numerical results will be given, where water distribution network will be interesting application area.

The big size of the disk space is necessary for these models allocation, therefore the method of the virtual data models is offered. The period of life of the created models is not limited in time, they do not influence the real data, and they do not occupy the place on the storage devices. The examined virtual data models are developed within the frames of the creation of the Decision Support System of Latvian Railway. However the received results have a universal character. Thu, 22 Aug 2024 15:43:41 +0200 http://popups.lib.uliege.be/1373-5411/index.php?id=2476 http://popups.lib.uliege.be/1373-5411/index.php?id=2479 System failures are usually observed during regular maintenance or inspection and this is especially the case for systems in standby or storage, which is common for safety critical systems. A periodic inspection policy is usually adopted. During the inspection, a lot of information is gained about the status of the system. Such information should be used in deciding upon the time for the next inspection. Hence sequential inspection is more appropriate, especially when the aging property of the system is unknown, and has to be estimated with the information from inspection. In this paper, a model is developed and sequential inspection strategies are studied in this situation. The focus is on the case when there are multiple systems inspected at the same, but discrete times. We also do not assume a known distribution of the system lifetime, and the estimation of that is incorporated into the analysis and decision-making. An availability criterion is considered and numerical example is provided to illustrate the procedure.

We demonstrate a mapping between the twistor algebra of the complex 8-space and the spinor calculus of 5D Kaluza-Klein geometry which attempts to unify Gravitational and EM theory. Our quantum formalism demonstrates that solving the Schrödinger equation in a complex 8D geometry yields coherent collective state phenomena with soliton wave solutions. The model shows that standard quantum theory is a linear approximation to a higher Dimensional complex space. Through this formalism we can assess that complex systems can be defined within conventional quantum theory as long as we express that theory in a hyper-geometric space. We utilize our complex dimensional geometry to formulate nonlocal correlated phenomena, including the quantum description of the 1935 EPR paradox formulated with Bell's theorem. Tests by Clauser, Aspect, Gisin have demonstrated that particles emitted with approximde simultaneity at c remain correlated nonlocally over meter and kilometer distances. As Stapp has said, Bell's theorem and its experimental verification is one of the most profound discoveries of the 20th century. We will demonstrate the application of our formalism for complex systems and review the history of our model from 1974.

The oriented material point became a principle object for the study, while in Newton mechanics it was just a point. The space-time in new mechanics is represented by l0 dimensional fibre bundle, where 4 translational coordinates form base and 6 anholonomic angular - a fibre. The principle consequence of the new mechanics is the connection between the general relativity theory and quantum mechanics. In non relativistic approach it is possible to establish the theoretical foundation of "jet like motion without rejection of mass". This conclusion was verified by experimental results with 4-D Gyroscope.

That structure's significance is manifested through the Kähler calculus of differential forms. Based on Clifford algebra, this calculus supersedes Élie Canan's. It revolves around Kähler's equation, a generalization of Dirac's. The juncture of geometry and the calculus is to be understood in the sense that, through the aforementioned implementation, one can create a Kaluza-Klein type structure where the torsion part of the structural equations is given by a fully geometric Kähler equation. Its input is the differential form whose exterior covariant derivative is precisely the torsion in its role as output differential form, thus yielding a closed geometric system of structural equations.

Those equations pertain to "the physical field" (actually its potential), including the quantum sector. This is demiurgic TP. We signify, as Élie Cartan did, that the field equations imply that spacetime is teleparallel, and not just simply compatible with TP. A "mother of the physics" results, for lack of a better name, meaning that physical "systems" i.e. concepts,formulas and physical theories- emerge from it. We take only a few timid steps in the study of the idiosyncratic manifestation of anticipation in such a theory. Our study of emergence will, we hope, help others deal more authoritatively with anticipation for this new frontier of natural science theory.

We outline how the representation is derived, the properties of the representation, and how the form can be used. Think of D as an infinite table of 1's in any representation e.g. binary or hexadecimal. Any specified column Di of the table has the property that when multiplied with a row Di, the result is a representation of -1. Di multiplied with Dj anticommutes as - (Dj*Di) and produces Dk in a way identical to Hamilton's quaternion i, j, and k. With an infinite and uniquely identifiable set of such triad forms D can be considered both a symbol and because of this behaviour, an alphabet.

This explains why Einstein and others failed in obtaining a fields theory that unifies the electromagnetic and gravitational fields applying only one temporal axis. Moreover, each of these two temporal axes can be split into two axes, one representing microscopic time and the other representing macroscopic time. Thus the microscopic and macroscopic phenomena occur in different subspaces of the entire space. This prevents contradiction between relativity and quantum theories, due to microscopic spatial discontinuities. Fri, 30 Aug 2024 09:39:39 +0200 http://popups.lib.uliege.be/1373-5411/index.php?id=2675 http://popups.lib.uliege.be/1373-5411/index.php?id=2677 Ideomotor theory explains developmental and executive aspects of action control departing from the proposition that actually ongoing behaviour is sensorily guided by the anticipated consequences of its own future effects. The present paper discusses a view which is rooted, in opposition to the "computing" approach of the AI tradition, rather in the "tuning" view of J.J. Gibson and his followers, departing from the framework of a transactional interpretation of quantum brain dynamics. Based on the Wheeler-Feynman absorber theory, this approach accounts for advanced/retarded anomalous resonance coupling in brain dynamics in analogy to quantum entanglement effects between distant twin particles (Einstein-Podolsky-Rosen paradoxes, quantum non-locality, teleportation). Beyond the quantum mechanical micro scale, indices for similar absorber site driven resonance coupling effects have probably been found at the cosmological macro level too, namely, by the soviet astronomers Kosyrev and Nasonov. Hypothetically, their observations might be explained by a mechanism of anticipative resonance coupling with the advanced future positions of stellar objects expanding to the same time scale as their gravitational forces are retarded due to the limitations of light speed. As has been shown by Dubois, anticipation is needed in macro- and micro-cosmological feed-back loops in order to avoid entrainment towards a chaotic attractor. This argument seems applicable to an advanced resonance coupling solution for cortical synchronisation and ideomotor action control too. Neuronal loops are fed into a network of socalled synfire chains, the timing of which is critically dependent on anticipatory predictions of the next input in order to adjust their output in a way which stabilises nonlinear brain dynamics. In order to get a synchronous visual flow in both left and right brain hemispheres, as is needed in order to account for the coherence of micro timing in binocular stereo vision, the temporally delayed information of the left and right eyes' visual hemifields, which are initially processed in different hemispheres, should be integated with anticipated versions of their complements in order to close the time gap. From this point of view, popular experimental data, e.g. about iconic memory, backward masking and the Libet experiments under actual discussion, may be reinterpreted in line with the hypothesis of an absorber theory for quantum brain dynamics.

'Alternative (a)' says that 'QM is the complete truth about the physical world (in the sense that it will always give reliable predictions concerning the nature of experiments) at all levels and describes an external reality'.

Nottale and Da Rocha explain the findings in terms of fractal hydrodynamics modellable in terms of Schrödinger equation with an effective Planck constant whose general form is fixed by Equivalence Principle. In this article an interpretation as a genuine quantum effect based on quantization of Planck constant allowing dark matter to be quantum coherent in astrophysical scales is discussed. The model predicts correctly the value of the velocity parameter appearing in the gravitational Planck constant and explains the appearance of its harmonics and sub-harmonics. A quantum model for the formation of planetary system is proposed. Some numerical coincidences support the view that quantum coherent dark matter could be also responsible for the properties of living matter.

Whence, any reversible Boolean function can be computed. Coherence in water leads to fractal properties for imprinted frequencies and to the possibility of anticipatory signal propagation. This is interpreted in terms of the Josephson-Effect coupling between phase coherent domains in the frequency imprinted water.

It is secreted by living cells, and continuously recycled with very different uses. Our body materials undergo phase changes, by which we can adapt to very different contexts. This material derives from our context, and is to be regarded as dynamically interwoven with it. The state changes in its composition relate to transitions between degrees of freedom, which relate to different dimensional states. The relationship between 1D, 2D, 3D and 4D are integral part of our body's functioning as a dimensional operator. This text relates these to our freedom of choice, and discusses how we can see Freedom of Choice to be incorporated into our body. This understanding has deep consequences for health care. 'Modern' medicine still adheres to the tenets of Classical Science. Our body however is not ar inert object and cannot be treated as such. Our ability to use freedom of choice is of direct relevance for (self) healing.

One of the simplifying assumptions of classical science, studying objects, was that the human observer could be obiective. This led to an irresponsible situation: the scientist as outsider of reality ('playing god'). By this assumption scientists are explicitly implicitly unable to cope with the consequences of their own creation. This approach is leading to extensive damage to Earth, and humanity, and it is necessary to focus on the hidden role of the scientist in science. It will be seen that this focus makes it possible to address what seems to be the blind spot of science: the scientist himherself, and the vital difference between the nature of living beings and dead matter. It appears necessary to, literally, bring science to life. Fri, 30 Aug 2024 14:33:41 +0200 http://popups.lib.uliege.be/1373-5411/index.php?id=2727
