Gaia Takes A Billion Stars Under The Magnifying Glass

Gaia Takes A Billion Stars Under The Magnifying Glass

A new space telescope to deliver ground-breaking discoveries about the universe the planned Gaia mission will provide revolutionary insight about the development of our Milky Way Galaxy and the star contained the term Gaia stands for global Astrometrics Interferometer for Astrophysics. It is an 11 metre satellite is equipped with a special telescope. In 2011, Gaia should be shot with a Russian rocket into space. To understand the development of our own Milky way, we need to examine the star in her closer. Gaia aims therefore to clarify the following questions: in which areas have emerged the star? How exactly is this creation process? When are very many stars? Gaia is to capture the light of a percent of the 100 billion stars in our Milky Way and evaluate with unprecedented accuracy. Space in their sights the developers also hope to be able to track down still undiscovered, astronomical objects with Gaia. Example way brown dwarfs, objects that are actually too big for a planet, but too small for a star are. They are something in between, one might almost say a cosmological mishap.

Their mass was not sufficient to ignite fusion in their own minds that needed it to transform himself into a star. Further, several 10.000 planet of alien solar systems to be discovered and investigated. A wealth of information there is the so-called supernovae exploding stars. Twenty thousand of these events to find Gaia and analyse. White dwarfs are so far difficult to observe.

These are remnants of stars that already have their lives behind. Also our Sun will end someday, more precisely in about 6 billion years ago, as a white dwarf. His profile: A ball, not much bigger than the Earth, light weak and relatively cool compared to an active star. Before however completely stop these white dwarfs, emit weak light, Gaia will give them a few secrets elicit. The already known objects in our Milky Way Galaxy from the local computer can be admired with an astronomy software. The Gaia mission will take 5 years and your developers will cost around half a billion euros. Who was there first: the Galaxy, or a black hole? Today, the process of galaxies is not fully understood. There is a black hole, in the Centre of almost every large Galaxy in our Galaxy, the milky way. The question, who was now first there is a mystery but: the Galaxy, or the black hole in its Center. To create a black hole, star or matter amounts must be present. There are stars but only in already existing galaxies. On the other hand the energy and matter emissions black cause holes only, that can matter in its surroundings is to heat up and structures are necessary conditions for the formation of a Galaxy. The solution to this paradox is the subject of current research.

Medical GmbH

Combination of speech recognition and semantic analysis of medical texts of Fribourg, July 31, 2013 – the Averbis GmbH and the RHoN-KLINIKUM AG within the framework of the research project “semanticVOICE” jointly develop a software solution that combines speech recognition and content analysis of text and reduces the complex manual coding of medical documentation to a minimum. The Federal Ministry of education and research (BMBF) has recognized the potential of the project and is involved in “semanticVOICE” with federal funds. The evaluation of free lyrically created medical documentation holds a wealth of evaluation options for the entire health care system. The speech technologies now prevail in many areas of medicine. A computer now detects not only the medical nomenclature, but understood their content meaning, also called semantic text recognition. So far medical information systems can offer only separated from each other either language or semantic enrichment. The result is in the settlement medical services of significant administrative burden.

The coding of medical services is connected with considerable administrative effort in essentially been a manual process. Main reason for this is that the medical documentation is largely unstructured and not automatically be evaluated. Technical terms, parts kits, bulleted lists, stylistic vary and the language of doctors is quite different from the common speech. To Dr. Philipp Daumke, co-founder and managing partner of Averbis GmbH: “doctors know the enormous administrative burden in the coding of medical services only too well.” Instead of to take care of patients, doctors spend valuable time with Office work.

We work on an intuitive solution, to minimize this overhead”, so Dr. Daumke continue. So far, there is worldwide no application on the market that combines a voice recognition and semantic analysis of medical texts. semanticVOICE”want to automate this process. The benefits for the health care is obvious: the automated coding of diagnoses, tests and treatments for billing purposes and plausibility check of the accounts of medical services offers substantial savings in many areas. The computer sees the doctor, various improvements of quality and accessibility of services in the health care sector are possible. Last Friday, the start of the project coincided with the kickoff.

Measuring Device PCEAC

Measuring Device PCEAC

The new CO2 measuring device PCE-AC 2000 PCE Germany GmbH is for monitoring indoor air quality jurisdiction. It has temperature and humidity display a CO2 – and evaluates the indoor air quality on the basis of the combined measurement of CO2 content, the temperature and the air humidity. Concentrated work is a prerequisite for quality and good work results. Confounding factors, such as a high carbon dioxide content affect our concentration. The new CO2 measuring device PCE-AC 2000 PCE Germany GmbH is for monitoring indoor air quality jurisdiction.

It has temperature and humidity display a CO2 – and evaluates the indoor air quality on the basis of the combined measurement of CO2 content, the temperature and the air humidity. Carbon dioxide is a chemical compound containing carbon and oxygen, which can cause some side effects with us in increasing concentration, such as fatigue, concentration problems, or headaches. A high concentration of carbon dioxide is produced fast, when there are several people in the closed rooms with lack of ventilation. Especially for meeting, lounges, schools and conference rooms the new CO2 gauge particularly suitable. Well-being is affected by more than 800 already ppm concentrations. The PCE AC 2000 has a calibration function to the adjustment and setting back the good “-value.” At the same time the CO2 level will be shown in detail, thanks to the optical bar graph display and the 3 color stale air traffic.

The large display makes it easier to read the values. Alarm limits can be freely selected and an acoustic and optical alarm turns on when the limits are exceeded immediately and thus warns against an existing threat. The instrument covers a range 3000ppm. The CO2 measuring device PCE-AC 2000 ensures optimum performance, without headaches or inertia-feelings, triggered by a high carbon content. Also the fact that the carbon dioxide displacing oxygen important for us, takes our Well-being. In classrooms or offices, where many people come together, the CO2 content in the air is particularly important. More information under:..

Precision Without Position Sensor

Precision Without Position Sensor

Piezokristalliner phase slider with Picoactuator technology in the laser measurement technology used for adjusting optical path lengths phase shifter. This move optics in terms of wavelength, so in a range below one micrometer. Essential is that the adjustment will be fast and stable. For the new phase shifter S-303.BL replaced physics instruments (PI) classic Piezoelectric ceramic PZT actuators (of lead titanate lead zirconate) by Picoactuatoren of a crystalline, lead-free material. This Picoactuatoren is characterized by a particularly high linearity, so that the precision positioning in the unregulated operation is possible. With a travel of 0.3 micrometers, they reach an accuracy of 6 nanometers, which corresponds to a linearity 2%. Compared to classic Piezoceramics, Picoactuatoren but have a lower displacement.

Ideal applications are therefore, where it is highly dynamic, small travel and high precision requirements are required. The unregulated operation omitted in favor of system bandwidth and costs on the use of a position sensor. This will simplify the mechanical construction and electronic control, time does not apply. This is the S-303.BL a precise and yet dynamic drive for optics in terms of the wavelength of light. Physics instruments (PI) is known for the high quality of its products and occupies a leading position on the world market for precise positioning technique for many years. For 40 years, develops and manufactures PI standard and OEM products with piezo – or motor drives. In addition to three German plants, PI is represented worldwide with eight branches and a total of over 500 employees.
