How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
After my professional retirement, I switched from working in the subject “radar data processing” to “cosmology”. I consider that the energy density of the gravitational field is negative. However, the existence of an absolute negative energy density violates physical laws. Consequently, the negative energy density of the gravitational field must be compensated by a cosmic positive energy density. The cosmologic implications of this compensation is the kernel of my contribution.
Sabine Hossenfelder opened the discussion by pointing to too large structures in the cosmos, which cannot be the product of a single event. If the paradigm in cosmology is no longer the big bang, what else could it be? First issue is the topology of the universe. Big bang proposes a topology with the centre of gravity of the original matter involve...
In this paper, a method for precise tracking of aircrafts based on Time of Arrival (TOA) determination of transponder signals is presented. Target location via multilateration based on Time Difference of Arrival (TDOA) measurements is a well known powerful method. In recent time, methods of target location using direct TOA measurement processing wi...
The air traffic in Europe is subject of detailed research for reorganization. For a relevant research accurate simulation of different traffic categories is required. The conventional simulation techniques comprise mature models of aircraft behavior but do not include interactions between traffic objects. With trajectories corresponding to a highly...
An operational Air Surveillance System shall generate a stable and reliable air picture. In dense target situations the quality of available sensor data is reduced. System models which take into account correlated flight paths of aircraft formations help to compensate the lack of information in dense situations. The aim is to improve the tracking c...
In a belt pinch device, a hot, high-beta plasma is produced by the method of fast shock compression. For this heating method, the radial equilibrium depends upon the time evolution of the fast rising magnetic fields outside the plasma. A simple mathematical model for plasma compression and relaxation toward radial equilibrium in the case beta = 1,...
Check an alternative to the Doppler-Effect explaining the red shift of radiation emitted by galaxies The following short text is the complete contents of the project: Let us assume a universe that has a finite size of about 14 billion light years. Concerning its geometrical properties this universe is completely isotropic and homogenous, which means that the geometrical structure is the same at any place and in any direction. Because of its finite size, any traveller will finally arrive at his starting point on his perfectly straight path after a way of about 14 billion light years. The finite size automatically implies that this universe is not Euclidian which means that it has a curvilinear structure. The isotropic nature of the geometry inevitably leads to an intrinsic spherical structure with a radius R of 7 billion light years. According to the space concept of general relativity the curvilinear structure causes a dilatation of the length measure. What remains is the question, how that dilatation is related to a distance D covered in that space. Pragmatically the dilatation corresponds to the relation between the distance and the spherical radius. This means at a point in space with a distance D from the starting point there is a geometrical dilatation with a factor of (1+D/R). The resulting dilatation effect along any given path is given by the integration over the dilatation relation, which leads to an additional factor of (1+D/(2R)). For a light beam starting at any point, this means that after a distance D it is in a space region with the virtual radius R+D. And compared with the starting region the beam has experienced an effective space dilatation with the factor (1+D/R)(1+D/(2R)). For the light beam this means that it now has an increased wavelength. As a consequence, an observer at a distance D from the light source will register the light beam with a wavelength approximately increased by the factor (1+D/R) for D<<R. Is it coincidental that this simple model fits to the linear behaviour of the observed red shift in our Universe? Is it also coincidental that the nonlinear term of the quadratic expression approximately also corresponds to the increased red shift observed at extremely distant space objects in our Universe?
The Aim of the project is to provide a generator for military and civil air situation scenarios. The purpose of the scenarios shall be operator training, system validation, traffic optimisation, determination of security or overload problems. Existing multipurpose scenario generators use flight plans as edition base. In this project, flight paths derived from real traffic are used. The flight paths are generated by a smoothing tool, which processes radar data. The outputs of the smoothing tool are flight paths headed by track-number, call sign, aircraft address, and a list of mode switches. The flight path is described in terms of way points (time, latitude, longitude, height). A database intrinsic function virtually generates an analytic path, with arcs and straight sections. The analytic path matches to the first, the third and any impair way point. The direction in the matching points matches to the direction to the next pair way point. The database is filled with hundreds of thousands real paths and allows to combine selected, modified and newly generated trajectories. Variable selection criteria including geography, time, manoeuvre type, aircraft performance and so on, allow assembling scenarios for multiple purpose. A scenario player allows viewing of the scenario, calculates radar detections, and provides air situation information in an arbitrary resolution.
The aim is a Simulation System, which provides a database with way Points derived from Radar data. The way Points contain (Latitude, Longitude, Height) and time. An intrinsic function of the database generates an analytic path from the way Points, which exactly matches the first, the third and any further impair way Point. With this database the user is able to create Scenarios based upon real flightts combined with artifical paths or modified real flights.
