A planetary trains for multi-speed is mainly used for automation in industries of automobile. A planetary
gear train is represented by a graph. It is identified by (i) number of vertices and their connectivity (ii) number of edges and their types and values (iii) fundamental circuits, their size and adjancy. Connectivity of individual link is a property characteristic of kinematic chain. It is possible to identify a planetary gear,therefore of using sets of labele (decimal numbers representing connectivity ) of individual link. The
connectivity of vertices , edges values and circuit values, related to design invariants which in turn indicates the possible behavior of the gear train ( for example capacity of power transmission, speed ratio and power carculation). For a specified degree – of – freedom a number of planetary gear kinematic chain (PGKCs) are selected and hence planetary gear trains (PGTs) can be formed with a given number of links
and joints so that designer must be able to select to select the best train from the view point of say velocity ratio and capacity of power transmission, space requirements etc. Synthesis of planetary gear kinematic chain and planetary gear trains has been studied(1-9). Almost all reported work deals with only
identification of distinct chains. Besides providing an atlus of chains, this in itself does not provide any help to designer in the selection of best possible gear train. In the present paper a simple method based of circuit property ( based on link-link shortest path distance and degree of links) is presented to determine the topology values of power transmission efficiency and topology power transmission capacity of five-links PGKCs and their distinct inversions

This paper represents a joint effort of various scholars, independent scientists and a student operating through the Interstellar Travel MeetUp group, based in Washington, D.C. in the United States of America. The project was presented during the 68th International Astronautical Federation Congress, which took place in Guadalajara, Mexico in 2016. Our paper provides a systematic evaluation of power systems in terms of their power generation capacity, size, risks and availability led to the finding that no current one single power system can be relied upon for interstellar travel. Our contribution offers considerations on topics such as space resupply stations, wireless power transmission to spaceships (while at high velocity, using tracking/tethering with lasers), as well as harvesting drones. Futuristic propulsion technologies like the ionic levitation, laser, warp and solar concentrator are considered as alternatives for current propulsion systems. In addition to placing an emphasis on fundamental physics and propulsion research, the authors propose two novel initiatives that will advance interstellar technology while producing already-valuable technologies for terrestrial and orbital use: 1) An educational development initiative – The ‘Nicola Energy City Kit’is based on existing wireless power transmission technology and existing CanSat technology – to advance wireless power and data transmission for terrestrial and interstellar use. These technologies can affordably be tested on Earth first, and then in space. We propose a broad-based open education program that also motivates students to engage in STEM-related jobs. 2) A mobile save testing bed (‘sandbox’) for radical energy concepts – The UMPH lab is an unmanned outpost that accumulates large quantities of matter in save distance from Earth and conducts autonomous experiments, while harvesting energy or matter for the science and in-orbit resupplies.

This is my seminar in utilization of gaseous nuclear core technology for terrestrial applications, Gaseous core nuclear reactors are preferred due to the fact that they have lower nuclear wastes and they have higher thermodynamic efficiency. Gaseous core nuclear reactors can also be used for spaceflight propulsion purposes. Contact me at drguven@live.com for further information or for joint research opportunities.

The report presents a concept model for establishment of a scientific-information complex with thematically distributed satellite and subsatellite data base for the aerospace test sites on the territory of the republic of Bulgaria. The subject matter of the scientific-information complex will be: establishment, development, training, collection of thematically oriented data and transfer of techniques, instrumentation and technologies for remote sensing and monitoring of the environment, unfavourable and hazardous natural and anthropogenic processes and phenomena. The scientific-information complex will be used as a system, providing easy access to the data, their quick visualization, processing and analysis. It will support the scientific-research activity of the scientists from the BAS institutes working in the field of earth sciences and the Centre for Aerospace Monitoring at the Ministry of Emergency Situations. The complex will be also used to improve the training provided to Master and Post-Graduate Students in the field of Remote Sensing of the Earth.
