  • This freeware program visualizes pathways (KEGG, BioCarta, GenMAPP, ...). The user has the possibility to display any kind of quantitative data from gene and protein experiments directly within the pathways (colours represent the value). The linking between the pathway items and the experiment data is done over the gene or protein names and their accession numbers. Furthermore the user has a quick overview on the gene/protein with the collected links in the web-interface (direct links). This program includes only a small part of the functions from the software GENOM 2005.
  • AllTrans can be used for world wide professional coordinate transformations between international and national coordinate systems with or without geodetic datum change. Transformations between State-Plane-Coordinates (NAD83, NAD27, Transverse Mercator, Lambert, Soldner-Cassini, Mercator, EOV, Krovak, LV95, Pulkovo-Gauss-Krueger, Gauss-Boaga,...), UTM-Coordinates, Geographical- and 3d-Cartesian-Coordinates. Manual input and File-Import/Export (ASCII). If the geodetic datum of Start- and Targetsystem is not identical there is a datum shift possible (3-Parameter-Molodenski or 7-Parameter-Bursa-Wolf). AllTrans is available in English/German and there is also an Online-Help available. For all countries there are predefined datum shifts to WGS84. For higher accuracies it is possible to calculate individual parameters using identical points. These parameters then can be stored to the database in AllTrans. The calculation can be done with a Standard-L2-Adjustment or otherwise using an adjustment with reweight ...

  • Analog is a simulation software for analogical, digital or mixed, linear and non-linear electronic circuits. It includes a schema capture, a simulator, a module for editing results (time domain, Fourier domain) and a module for optimising circuits. The simulator uses the symbolic computation techniques for solving the system of equations of the circuit. By principle this resolution is performed accurately, without any iteration and without any numerical round off generating errors. Its main functions are the following: Hierarchical and graphical schema capture. Analogical, linear and non-linear components. Native models of non-linear capacitors and inductors, temperature dependent resistors, magnetic core inductors and transformers with hysteresis, delay lines and filters of Butterworth, Bessel, Chebycheff and Legendre, current or voltage sources of different types, voltage or current multipliers, diodes, bipolar, JFET, MOST and MESFET transistors. Native models of gates, flip-flops, different types of digita ...

  • Software AnyGraph created to simplify the development of system models used in the calculation of reliability of complex technical systems and their analysis. The basic concept is to provide software AnyGraph model as a set of interacting components (technical elements) and logical connections between them. Logical connections define specific conditions for implementing the nodes (elements of the technical system) of its functions. Built using the graphical editor AnyGraph model has a high degree of visibility, as a rule, the structure of the created model follows the principle technological scheme developed at different stages of the study of technical documentation projects.
  • Of similar accuracy to that used to compile published Nautical Almanacs but with a catalogue extending beyond Barnard's Star; it can be used as a sight calculator or definative astronomical reference. Multiple sights can be plotted/ combined while allowing for changes in course and/ or speed. Once an altitude and bearing has been entered, a list of potential bodies will be offered so that ambiguous sights will be immediately apparent. The other data available is comprehensive e.g. a Star Chart, twilight information, Moon phases and Eclipses. It will even print conventional Nautical Almanac pages for the full range of dates; 9999BC to 9999AD. The AltAz screen can be used to plan sights or to list bodies around a point on the celestial sphere either by altitude/ azimuth or by Declination and Hour Angle. The outlines of the constellations is the best available including ones like Sextans which rarely look like a sextant. Bayer/ Flamsteed designations are provided for over 3,400 stars together ...
