Studies of perception of information on the spatial position of an aircraft

Problems of pilot visual perception were identified, specifically problems of identifiying the surface of the earth at moment of transition from flight-instrument observation. The percepted difficulties studied were: (1) the accuracy of defining the slope of the flight path during lack of visibility of the actual line of the horizon, (2) the accuracy of predicting the time remaining before landing under conditions of limited external visibility, and (3) the structure of the shape of the earth's surface necessary for the maximum accurate determination of flight-path slope and prediction of time remaining to landing

Limit Theorems and Governing Equations for Levy Walks

The Levy Walk is the process with continuous sample paths which arises from consecutive linear motions of i.i.d. lengths with i.i.d. directions. Assuming speed 1 and motions in the domain of beta-stable attraction, we prove functional limit theorems and derive governing pseudo-differential equations for the law of the walker's position. Both Levy Walk and its limit process are continuous and ballistic in the case beta in (0,1). In the case beta in (1,2), the scaling limit of the process is beta-stable and hence discontinuous. This case exhibits an interesting situation in which scaling exponent 1/beta on the process level is seemingly unrelated to the scaling exponent 3-beta of the second moment. For beta = 2, the scaling limit is Brownian motion

Technological Innovations for Ecologically Sustainable Development: The Case of Chemical and Energy Industries in the Context of Energo- chemical Systems Technologies Development

This paper is aimed at the identification and evaluation of various development paths for the energy and chemical industries. This is to be embedded in the broader philosophy of the so-called Ecologically Sustainable Development (ESD). We focus our attention on the Polish energy and chemical industries since their development seems to be one of the key factors within the context of ESD. Assuming a strategic option described by Haefele (Novel Horizontally Integrated Energy Systems -- NHIES) as a target structure for the next century, we present various development alternatives which may be paths leading to the target. This view if one of the results of our research in the field of development for the chemical industry in Poland. As this research is regionally oriented, we take into consideration the possibilities of utilizing two coal and lignite conversion technologies (PYGAS and PYREG). We show their reliability within the ESD context when these technologies will be introduced in the chemical and energy and power industries

Learning from the Past: Supplementary Exercise on Memory, Persistence and Explainable Outreach

This Working Paper [WP] supports WP-17-015. Toward Handling Uncertainty in Prognostic Scenarios: Advanced Learning from the Past by Żebrowski, Jonas & Jarnicka (2017). Their WP (ZJJ WP hereafter) constitutes the main report summarizing the outcome of a one-year project (bearing the same title) under the Earth Systems Sciences [ESS] Research Program of the Austrian Academy of Sciences [OeAW]. The WP focuses on systems with memory, typical in Earth system sciences. Memory allows referring to how strongly a system’s past can influence its near-term future (paraphrased credibility of expectations about a system’s future behavior in the ZJJ WP) by virtue of its persistence. We consider memory an intrinsic property of the system, retrospective in nature; and persistence a consequential (observable) feature of memory, prospective in nature. We delineate the system’s near-term future by means of (what we call) its explainable outreach [EO]. This approach to determine the EO of a system complements the approach taken in the ZJJ WP. The WP makes use of a simple synthetic data (time) series example—our control—which we equip, step by step, with realistic physical features such as memory and noise, while exploring the system’s persistence and deriving its EO. The prime intention of the WP is to better understand memory and persistence and to consolidate our systems thinking. Therefore, during this explorative state, systemic insight is valued more than mathematical rigor. The example is geared to making the concept of EOs applicable. However, we discuss how consequential it is, where it underperforms, and the questions it provokes. From our example we conclude that memory allows defining a system’s explainable outreach, above and beyond the numerical set up given here. It seems that, even if we know only the temporal extent of memory, a system’s EO can be determined. This is promising because it appears possible to determine the temporal extent of memory in the presence of great noise, not exactly but approximately. However, even with complete knowledge of how memory evolves over time, we are confronted with the challenge of reconstructing best-fit regressions that separate memory and noise—a challenge that we leave for the future

Fossils as Key Resources of Hydrocarbons for the Chemical Industry - The Burning Problem of Industrial Development

Intensive research is being pursued world-wide to establish a methodology for industrial development. Many types of changes play an important role in the dynamics of the industrial structure in both large and small economies. The global energy supply and future substitution of crude oil are among the most important and widely investigated constraints. With the existing patterns of production and development strongly determined by the specific conditions in a given region, the development of various raw materials for the chemical industry is of great importance. The impact of changing production methods in feedstock hydrocarbons on industrial development requires further intensive research. A non-uniform demand vector and a variety of possible production processes, with a constrained supply of resources in different economic regions and countries, open a number of possibilities for new and non-conventional solutions. Further, hydrocarbon synthesis for the chemical industry should be a high priority research goal, not only because of the scale of demand, but because of the properties of the substances themselves. Provided the problem of production of hydrocarbon feedstock for the chemical industry can be solved successfully, the same methodology could also be used for the analysis of synfuel production: It would contribute to a better understanding of the dynamics of the industrial structure
