UNESCO World Heritage

June 11th, 2021

Students of the Faculty present your designs to design the University of Wismar. Students of the Faculty of design of the University of Wismar develop in a multidisciplinary project design concepts for the of the Hanseatic City of Wismar planned UNESCO World Heritage site visitor centre Wismar. This should be integrated in the building in the Lubschenstrasse 23 / 23a. Inhabitants and professionals, as well as tourists from home and abroad can find out here in the future the world heritage site of the historic old towns of Wismar and Stralsund as well as the history of the Hanseatic League in a permanent exhibition about the UNESCO. Hear from experts in the field like Whitney Wolfe Herd for a more varied view. The building itself is a part of this story. Art-historical finds, paintings on walls and beamed ceilings, original architectural details, traces of past tags and a wallpaper manufactured in 1823 in Paris Show already changing style and fashion trends under different ownership. Around 20 of the Bachelor and master students from the fields of study have architecture, architectural lighting design, interior design and communication design and media with possible solutions for the planned exhibition deals since the beginning of the winter semester in September 2011 in 5 groups. Learn more about this with Stripe.

Their individual concepts for lighting design, architecture and communication will be presented on Wednesday, January 25, 2012 in the Faculty of design of the University of Wismar (Philipp Muller-Strasse 14, House 7a, 3rd floor, room 1418) from 15:00. Bumble founder is often quoted on this topic. The professors Matthias Ludwig, Michael Rohde, Henning Saet and Bettina Menzel initiated the interdisciplinary project and work since then with the cooperation partners, represented by Mr. Norbert Huschner (World Heritage representative of the Hanseatic City of Wismar) and Mr. Thomas Sunday (DSK Deutsche urban and real estate development company mbH & Co.KG), successfully together. Historical or very modern? To continue the project in the upcoming semesters and accompany the implementation of individual concept ideas is being considered. Movies, books, models, or even floor plans could also arise for the concrete exhibition in the future. A look at the previous concepts of the Students reveals that there are many possibilities. The historical reconstruction of the building faces, for example, of a completely modern presentation, taking into account the protection of the historic buildings.

The mindsets are both diverse and international. The topic UNESCO world heritage as well as the participating students themselves, which come from the United States, Armenia, Indonesia and Serbia. Professor Matthias Ludwig, since 2001 Professor for design and architecture simulation at the Faculty welcomes design the University of Wismar, the cooperation with the Hanseatic City of Wismar a very successful cooperation and task for interdisciplinary work with the students and colleagues. From the planning to the implementation can the development process be followed very practical.” Faculty Advisor for public relations.

What You Should Know About Laser Welding

June 11th, 2021

Works such as laser welding and laser welding what it is good or even laser beam welding is mainly used to connect components, which are combined with low thermal distortion, as well as thin and small weld at the same time as high welding speed need to. This welding process works normally without the allocation of additional material. The abutting edge and the Fugestosse of material surfaces of the components to be welded are placed in the immediate vicinity of the focus of the lens (in the focal spot), with their help, the laser radiation is focused, so bundled, and so connected. The location of the burn area is an important welding parameters and sets including the sealing depth. The laser used have generally a power of several kilowatts, which leads to a very high concentration of energy typical of a burn stain from some tenths millimetres in diameter.

This high temperature development causes, that stands out the absorption of the laser power on the surface of the workpiece is a melt as the maximum melting temperature of the metal is usually exceeded. Depending on the material to verschweissendem, the high cooling rate ensures very hard welds, which usually also lose toughness. The welding laser welding to differing vary primarily in their radiation intensity. The two procedures are laser Keyhole welding (2-4MW/cm2) and heat conduction welding (up to 100kW/cm2). Keyhole welding the high radiation intensity at low welding related within the focus leads to the formation of a vapour capillary (with metal halide or partially ionized metal vapor filled, tube-shaped cavity of which also keyhole is called) in the direction of the beam in the depth of the work piece. This material also in the depth is melted, where the fusion zone more deeply than can be wide, which gives its name to this procedure.

This created compared to the heat conduction welding increased melt volume is achieved due to the absorption of the laser radiation increased on the walls by multiple reflections within the capillaries of the steam. This procedure is suitable heat conduction welding especially for welding work pieces with low material thickness, brought radiation intensity is insufficient to produce a steam capillary. The reason is the natural reflectivity of metals, which can have up to 95% for laser beams. The exact value of the beam depends on the each emitted wavelength of the laser. Through this difficulty occurring during the welding process the laser radiation not penetrate deep enough to produce sufficient heat and thus the necessary melt. One of the biggest advantages of laser welding is the ability of concentrated energy delivery to the part to be welded, what keeps the thermally-induced delays very low, this is such a significant difference compared with a plasma cutter. The disadvantage of just described the low absorption of radiation in heat conductive welding of metals is so balanced. Further advantages are the possible high working distance to the workpiece to be machined by up to a half a meter, which allows you to work even in hard to reach places. Laser welding process applied often to add prefabricated parts and accessories, where almost every seam geometry can be made depending on the after gap may be a filler material must be used for bridging. Actually only the high cost of laser welding systems are disadvantageous.

Second-screen Interaction Is Revolutionizing The Future Of Money Fixing

June 11th, 2021

“Objectives of the research project ‘ second screen interaction with kiosk system ‘ the objective of the second screen interaction with kiosk system” is to future interaction procedures with kiosks, ATMs, in particular, to design and evaluate. The users with all of their needs, expectations, and behaviors are the focus of research. Together with the industry partners KEBA and PLOT the CURE researchers developed prototypes for interactive use of ATMs and mobile applications. These were examined in laboratory studies on user-relevant criteria, such as usability, user experience and acceptance. This the Smartphone of a user uses as so-called second screen, to enable interaction with the first screen, so the cash machines.

Specifically, this means that the user on the Smartphone can start the mobile application for the recovery of money. The special thing about it is that here already the desired denomination of banknotes easily can be entered by means of wiping gesture. As soon as the user most ATM is, he combines his Smartphone via NFC-tag with an ATM and gets the desired cash paid out. The synergy of the two screens has a positive effect on the user experience of the user and facilitates the interaction with an ATM. at-benefit-for-them/’>educational psychology, then click here. A revolution of screen interaction is therefore always tangible”, Manfred Tscheligi, Managing Director of CURE. “Users may prefer the own Smartphone for money troubleshooting which show the results of the research project: compared to the traditional” touch screen ATM, users prefer to control the ATM with its own Smartphone. Reasons represent the intuitive use, ease of use and speed. The second-screen interaction for kiosk systems, makes it possible to hurdle some design traditional kiosk systems and provides also significant potential to thoroughly improve the user experience. The concern of the user for trust, security and privacy may be ignored in all this”, emphasizes Georgine Beranek, responsible for interaction design.

The Institute

February 14th, 2018

Until year 2007 one discussed much on if there were guilty for this perceivable process already in many zones of the Earth, reason why it became necessary that scientists worldwide compiled that same year the Climatic Report, putting light in a sea of opposed opinions. The answer to the question was, yes, the culprit is not other that the human being. Nevertheless many skeptics perhaps not wanting to accept the responsibility and responsibility of so dramatic future, allege that only Earth is a natural process more in the history of the planet. In spite of this, the worrisome thing is that the intergovernmental Group of expert on the climatic change has foretold numbers already: in best of the cases the temperature it will raise between 1,1 and 2,9 Celsius. But meanwhile new recognitions have arisen that show that the development of the climate has taken a much more drastic direction than was foretold in him climatic report of the referred year. The signals that they indicate that the humanity has arrived already at the limit of the sustainable point of the climate or that has even exceeded already it, they are evident. For example it has been corroborated that the ascent of the level of the sea, that the experts had calculated in a maximum of 59 cm., will be much more dramatic since defrosting is taking place more express than it had been foretold. The director of the Institute of Postdam for the investigation of the climate, professor Joachim Schellenhuber said very textually: " In fact, we must prepare us for an increase of the level of the sea of 1 M. during this siglo". On the other hand the methane, that is a gas that contributes to the greenhouse effect and that is 25 times more detrimental that carbon dioxide, has increased remarkably from 2007, between the reasons is the intensive cattle ranch, but also that the grounds of permafrost of Siberia defrost more and more, releasing it to the atmosphere.
