A human being’s psychological state depends in part on the colors of the surroundings. One of the familiar effects related to this is alertness stimulated by bluish light of high color temperature and induced weariness by reddish low color temperature light such as evening sunlight. Hence, creating images approximating the visual color experience...

Our objective is to determine whether the Kreutz group of sun-grazing comets represent a material transport process that can be emulated. The Kreutz comets typically move through the solar system at 0.2% of lightspeed, 480-600 km/sec (1.3 million mph). This allows a typical Kreutz comet to cross the distance between Mars and Earth in as little as a...

While observations from Mars orbiters and rovers offer new views into surface details and improve with every new mission, most theories and models devised to explain the creation of mountains, canyons, craters and microscopic features are still those of the 19th century, from the time when Charles Lyell, Percival Lowell and Giovanni Schiaparelli we...

On October 18, 2014, comet Siding Spring (C/2013 A1) passed near Mars at ⅓ the Earth's lunar distance and showed an energizing effect on the upper Martian atmosphere of the whole planetary hemisphere and its magnetic field. While this effect might create concern about human Mars exploration, it provides an opportunity for insight into the true natu...

The solar wind streaming radially outward from the Sun offers a natural contact force for spacecraft propulsion. The Solar Sail is limited in degrees of freedom by the general unidirectional velocity vector of the solar wind. We discuss aspects of a focal natural comet stream opposing the solar wind direction, pellets of charged, incandescent matt...

The security mechanisms employed in today's networked en- vironments are increasingly complex and their configuration manage- ment has an important role for the protection of these environments. Especially in large scale networks, security administrators are faced with the challenge of designing, deploying, maintaining, and monitoring a huge number...
Conference Paper

Os mecanismos de segurança empregados em ambientes de redes atuais são de crescente complexidade e o gerenciamento de suas configurações adquire, portanto, um papel fundamental para proteção desses ambientes. Particularmente em redes de computadores de larga escala, os administradores de segurança vêem-se confrontados com o desafio de projetar, imp...

Since March 2021 the author's automated website https://areo.info/mars20 provides an easy to use interface to browse through all engineering camera color images sent by the Perseverance Rover's Navcam, Hazcam and also from its Watson camera. Ingenuity Helicopter's RTE color images are also published. The image processing corrects geometric distortion and applies a camera profile based on the camera's spectral sensitivity functions.
